My mother still cries about it.

Forty years later, she'll be sitting at the table, and her eyes will fill, and she says the same words she's said my whole life: "We had everything. We lost it all. And we couldn't give you children anything."

Mom, I have told you a thousand times — and I will tell you a thousand more. You gave me the greatest gift a parent can ever give a child. You gave me America. Nothing else matters. Nothing else even comes close.

Let me tell you what she means.
In Iran, we did have everything. My father spent thirty years helping build a nation — its cities, its schools, its roads, its hospitals. We belonged to a Jewish community that had lived on Persian soil for 2,700 years. We had a home, a history, a name that meant something.
And then, almost overnight, we had a target on our backs. Bullets cracked over our roof. Cars burned in our street. My father became a hunted man for two unforgivable crimes: he had served his country, and he was a Jew.

So he did the only thing a father can do. He sold everything we owned for whatever he could get, gathered his wife, his mother, and his four little boys, and he ran. Thirty years of a man's life's work — surrendered at the door, in exchange for our lives.

We were the lucky ones. That community was once a hundred thousand souls. Most never got out with what we did. Some never got out at all.

We carried away only what no regime could confiscate — our faith, our language, our poetry, and each other. And after a few years finding our footing, we came here. To America. To the one country on earth that looked at a family fleeing a regime that hated it… and opened its arms anyway.

We arrived with empty hands. And that is the wound my mother has never let go of — that after all they'd had, they gave us nothing.

But Mom, you don't understand what you gave me.

You gave me a country where I could pray out loud without fear. Where I could speak my mind. Where a penniless refugee kid could become a physician, a scientist, an author — where the only ceiling was how hard I was willing to work. You didn't hand me an inheritance. You handed me something no fortune in Iran could ever have bought: the freedom to build a life without looking over my shoulder.

That is a love only an exile understands. Not the calm, comfortable patriotism of someone born into safety — but the fierce, protective, almost desperate love of someone who has watched a homeland turn on its own people and knows, in his bones, how quickly it can all be taken away.

And that is exactly why I will never stay silent.

When you have watched a revolution promise heaven and deliver a prison — when you've seen radical Islamists and the intoxicating lies of socialism hollow out a great nation from the inside until it devours its own children — you do not take a single hour of American freedom for granted. And you carry one holy fear: watching it happen again.

I did not flee that fire to sit quietly while anyone strikes the same match under the country that saved my family. You do not escape the thing that destroyed your first home only to welcome it into your second. I love America too much — and I remember far too much — to let that happen without a fight.

So I spend my life trying to be worthy of the gift. Through medicine. Through science. Through my words. By defending the freedoms that saved us — free speech, free thought, the God-given right to choose — with everything I have. This country once invested in me with no expectation of return, only trust. I have been repaying that trust every day since, and I will until my last breath.

So this is my answer, Mom.

You did not send me into the world with empty hands. You placed in them the freest, most generous, most extraordinary nation in the history of mankind.

You gave me America.

And I will spend the rest of my life proving it was more than enough.
Happy 250th Birthday. 🇺🇸

God bless the United States of America. 🗽

​I have always adored Senator John Fetterman. In a Democratic Party that has descended into full-blown insanity and lunacy, he remains the one honest voice of sanity left standing. The last man who refuses to bow to the mob. While others sold their souls, Fetterman kept his. And that takes real courage.

​2/7
​The Democratic Party I once knew is gone. It has been captured by a radical coalition of Islamists, antisemitic socialists, and pro-Palestine extremists who openly cheer “from the river to the sea” and treat Hamas sympathizers as heroes. Fetterman has called this what it is: the “dirtbag left” having its “dancing days.” He said the party is becoming “an orgy of socialism” — and recent DSA primary victories in New York have proven him 100% right. 3/7
​These aren’t fringe voices anymore. They’re winning. Candidates who cram the most anti-Israel, anti-America rhetoric into their platforms are defeating traditional Democrats. Fetterman warned us: the outlook for Jewish voters in this party is now “bleak.” Because anti-Zionism has become the new litmus test — and too many in the party look the other way or join in. He stands almost alone calling it antisemitism.

​4/7
​They want to take your wealth and destroy what makes America exceptional. Socialists don’t build. They seize. They punish success. They want to abolish borders, ICE, police, and prisons while calling it “justice.” Fetterman has blasted colleagues who refuse to call out this madness. America’s excellence — our innovation, our freedom, our capitalist engine that lifts the world — is under direct assault from within his own party. He refuses to pretend otherwise.

I'm a cardiologist. The same meal eaten at 8 AM and 8 PM does completely different things inside your body.
A Lancet-affiliated study just confirmed it: the time of day you've consumed 50% of your calories robustly predicts your insulin sensitivity, waist circumference, and metabolic health — independent of what or how much you eat.
Same food. Same amount. Different clock. Different outcome.
Most people eat their biggest meal at the exact hour their metabolism is least equipped to handle it. 2/5
Your insulin sensitivity peaks in the morning and declines throughout the day. The same plate of food your body handles cleanly at breakfast produces a dramatically larger insulin spike at dinner.
Glucose tolerance drops. Thermogenesis — calories burned processing food — falls. By evening, your pancreas works harder, blood sugar stays elevated longer, and your body shifts from burning to storing.
A 2025 RCT proved it experimentally: women eating within an early window lost significantly more weight while preserving muscle mass — not because they ate less. Because they ate earlier.
Your metabolism isn't broken. It's on the wrong schedule.

I'm a cardiologist. Let me tell you about the most extraordinary act of patient agency I've ever encountered.
In 2024, a tech founder named Sid Sijbrandij was told by his oncologists that they had nothing left. His osteosarcoma — an aggressive bone cancer in his spine — had returned after surgery, radiation, and chemotherapy so brutal he needed four blood transfusions to survive it. He'd exhausted every standard treatment. He wouldn't qualify for clinical trials. The implicit message: good luck.
Most people accept that verdict. Sijbrandij — co-founder of GitLab, a company worth $6.4 billion built on the principle that information should be open and transparent — decided to treat his cancer the way he'd built his company.
He went founder mode.
He quit his day job. Assembled a dream team. Hired a geneticist named Jacob Stern, formerly of 10x Genomics. And then he did something no cancer patient has ever done at this scale.
He generated 25 terabytes of his own medical data.
Whole genome sequencing. Whole exome sequencing. Bulk RNA-seq. Single-cell RNA-seq across multiple timepoints. Full-body PET/CT scans. Organoid models grown from his own tumor tissue. Immunohistochemistry. Spatial transcriptomics. Every diagnostic modality that exists — run on his specific cancer, at his specific stage, from his specific body.
Then Jacob Stern fed it all to ChatGPT Not as a doctor. As what he called an "Iron Man suit" — an AI research partner that could synthesize 25 terabytes of genomic, imaging, and clinical data faster than any team of bioinformaticians. The AI identified patterns, surfaced relevant literature, generated hypotheses, and helped design therapeutic strategies that Sijbrandij's oncology team hadn't considered.
It identified a target called PANX3 — a protein highly expressed in his tumor but nearly absent in normal tissue. Exactly the kind of molecular fingerprint that makes precision therapy possible.
Then came the treatment cascade that reads like a medical thriller.
Sijbrandij filed five individual patient Investigational New Drug applications with the FDA. All five were approved within 48 hours. He flew to Germany for FAP radioligand therapy — a targeted radiation treatment that seeks out fibroblast markers his single-cell analysis had confirmed were dominant in his tumor. He received a checkpoint inhibitor to unleash his immune system. A personalized neoantigen peptide vaccine designed from his tumor's specific mutations. An oncolytic virus — a modified virus that infects and destroys cancer cells.
All of this — simultaneously — guided by AI-assisted analysis of his own data.

I'm a cardiologist. A study published four days ago in Nature Medicine just proved something I've been trying to tell you on this platform for months: your body is aging faster than your parents' body did at the same age. And that accelerated aging is driving the cancer epidemic in younger adults.
WashU Medicine analyzed blood from over 164,000 people and found that those born in the 1990s show a biological age gap 92% larger than those born in the 1960s.
Same chronological age. Dramatically older biology.
And the people aging fastest had up to 15% higher risk of developing cancer before 55.
Here's the part that should change how you think about your next blood draw. Here's the part that should change how you think about your next blood draw.
The researchers used an algorithm called PhenoAge that calculates your biological age from nine routine blood markers. Not exotic tests. Not expensive panels. Nine numbers you probably already have from your last physical:
Albumin — liver function.
Creatinine — kidney function.
Glucose — blood sugar.
C-reactive protein (hsCRP) — systemic inflammation.
Lymphocyte percentage — immune function.
Mean corpuscular volume — red blood cell size.
Red cell distribution width — red blood cell variation.
Alkaline phosphatase — liver and bone health.
White blood cell count — immune activity.
That's a basic metabolic panel plus a CBC plus hsCRP. Costs almost nothing. Available everywhere. You may already have these results sitting in your patient portal right now.

I'm a cardiologist. Let me tell you what I see in my practice that breaks my heart more than any clogged artery.
A patient walks in carrying five diagnoses — obesity, high blood pressure, type 2 diabetes, fatty liver, and gout — on seven medications. Each prescribed by a different specialist. Each treating one symptom. None of them talking to each other.
Nobody told this patient the five diagnoses are one disease.
They are five faces of the same metabolic dysfunction. And the root is almost always the same: chronically elevated insulin driving fat storage, inflammation, and organ damage simultaneously.
Medicine gave this patient a bigger bucket under every leak instead of fixing the roof.
Here's the roof. And how to fix it.
In 2025, the ICD-10 coding system — the official classification used by every hospital and insurance company in America — added a new code: E11.A. Type 2 diabetes in remission. Medicine now officially recognizes that type 2 diabetes is not a permanent, progressive sentence. It can be reversed.
The DiRECT trial in the UK achieved 46% diabetes remission at one year through intensive dietary intervention. A 2025 Indian study of 2,384 patients achieved 31% remission. A 2024 trial in Pacific Islanders achieved 23% remission — with some patients entering remission without significant weight loss, proving the mechanism is metabolic, not just weight-driven.
This is not theoretical. It's published, replicated, and now coded in the medical system. Your doctor can document your reversal.
Here's the protocol I walk patients through — step by step. 𝗦𝘁𝗲𝗽 𝟭: 𝗥𝗲𝗺𝗼𝘃𝗲 𝘁𝗵𝗲 𝗶𝗻𝘀𝘂𝗹𝗶𝗻 𝗱𝗿𝗶𝘃𝗲𝗿𝘀.
For the first 30-60 days, eliminate the foods that spike insulin repeatedly throughout the day: added sugars, sugary drinks, refined carbohydrates (bread, pasta, rice, cereals, pastries), ultra-processed foods, and excess alcohol.
This isn't about calories. It's about insulin. Every spike locks fat inside fat cells, drives fat storage in the liver, raises blood pressure, elevates uric acid, and fuels systemic inflammation. Remove the constant trigger and your body stops being in defense mode.
Cravings peak around days 3-7 and then drop dramatically. Most patients report a clarity of mind by week two that they haven't felt in years.

𝗦𝘁𝗲𝗽 𝟮: 𝗥𝗲𝗯𝘂𝗶𝗹𝗱 𝘄𝗶𝘁𝗵 𝗿𝗲𝗮𝗹 𝗳𝗼𝗼𝗱.
Every meal: generous protein (30-50g), non-starchy vegetables (half the plate), healthy fats for satiety (olive oil, avocado, eggs, nuts, butter). Protein at every meal is non-negotiable — it stabilizes blood sugar, preserves muscle mass, and keeps you full for hours.
No calorie counting needed at the start. When you remove the processed foods that hijack appetite signaling, most people naturally eat less without trying — because their leptin and ghrelin systems start working properly again.

New York has turned into 1979 Iran.

Some of you don't understand this yet.

I'm a cardiologist. After 40, stop guessing about your health. These numbers tell you whether you're building a long, vibrant life — or quietly declining without knowing it.

I run these on myself. I run them on every patient I care about. Most are cheap bloodwork. All are available now. And together, they paint a picture no standard annual physical will ever give you. Print this. Bring it to your next appointment. Your 60-year-old self will thank you.
ꟷꟷꟷ
𝗙𝗮𝘀𝘁𝗶𝗻𝗴 𝗜𝗻𝘀𝘂𝗹𝗶𝗻
Target: below 5 μIU/mL. Ideal: 3-4.
This is the 10-year warning bell your standard panel completely misses. Your glucose and A1c can look "normal" for a decade while your pancreas is working overtime to keep them there. Fasting insulin catches insulin resistance 5-10 years before your A1c moves. By the time A1c rises, the damage is already extensive.

𝗛𝗢𝗠𝗔-𝗜𝗥
Target: below 1.0.
Calculated from fasting insulin and fasting glucose. The single best measure of insulin sensitivity. Above 1.0 and your metabolism is already under strain. Above 2.5 and you're insulin resistant — even if every other number looks fine.

𝗛𝗯𝗔𝟭𝗰
Target: below 5.4%.
Not below 5.7% — that's the threshold where medicine calls you "prediabetic." By then you've been metabolically compromised for years. Optimal is below 5.4%. Blood sugar mastery is longevity mastery.

𝗧𝗿𝗶𝗴𝗹𝘆𝗰𝗲𝗿𝗶𝗱𝗲 : 𝗛𝗗𝗟 𝗥𝗮𝘁𝗶𝗼
Target: below 2. Ideal: below 1.
Your metabolic health crystal ball. This ratio predicts insulin resistance, cardiovascular risk, and metabolic syndrome better than any single lipid number alone. A ratio above 3.5 is a red flag regardless of what your total cholesterol says.

𝗔𝗽𝗼𝗕
Target: below 80 mg/dL for moderate risk. Below 60 for high risk.
I've written about this extensively. ApoB counts every atherogenic particle hitting your artery walls. A 2024 analysis found 54% of patients had dangerous levels that standard LDL testing completely missed. If you only know your LDL, you're driving with one eye closed.

𝗟𝗽(𝗮)
Test once in your lifetime.
100% genetic. 1 in 5 Americans are elevated. Triples heart attack risk independently of everything else on this list. Diet and exercise cannot lower it. The 2026 ACC/AHA guidelines now recommend everyone be tested. Most never have been.

𝗵𝘀-𝗖𝗥𝗣
Target: below 1.0 mg/L.
You can have perfect cholesterol and inflamed arteries silently preparing to rupture. hs-CRP measures the fire behind the plaque. The JUPITER trial proved that finding and treating inflammation saves lives — even when lipids look fine. If this number is elevated, your mouth, your gut, your metabolic health, and your visceral fat are the first places to investigate.

𝗩𝗶𝘁𝗮𝗺𝗶𝗻 𝗗
Target: 50-80 ng/mL.
Not the bare minimum of 30 your doctor accepts. Suboptimal vitamin D is linked to higher inflammation, weaker immunity, increased cardiovascular events, worse mood, and poorer outcomes across nearly every disease I treat. Supplement D3 with K2 — without K2, calcium deposits in your arteries instead of your bones.

𝗧𝗲𝘀𝘁𝗼𝘀𝘁𝗲𝗿𝗼𝗻𝗲 (𝗧𝗼𝘁𝗮𝗹 + 𝗙𝗿𝗲𝗲)
Men: optimal range 600-1000+ ng/dL total.
Declining testosterone is an independent predictor of cardiovascular death in men. It's tied to insulin resistance, arterial stiffness, visceral fat accumulation, and systemic inflammation. DHEA-S drops 10-20% every decade after 30. Tracking these isn't about vanity — it's evaluating your body's systemic resilience.

𝗕𝗹𝗼𝗼𝗱 𝗣𝗿𝗲𝘀𝘀𝘂𝗿𝗲
Target: below 120/80. Aim closer to 110/70.
Every point above optimal is cumulative arterial damage. Buy a home cuff. Measure morning and evening, seated quietly for five minutes, arm at heart level. White-coat readings in the office miss what's really happening. The smartest $40 investment in cardiac self-care.

𝗩𝗢𝟮 𝗠𝗮𝘅
Men over 40: above 40 mL/kg/min. Women over 40: above 35.
Cardiorespiratory fitness is the single strongest predictor of all-cause mortality — stronger than smoking, diabetes, or heart disease as individual risk factors. A landmark study in JAMA found that extreme fitness was associated with the lowest mortality with no upper limit of benefit. You can estimate VO2 max with a timed mile, a rower test, or a wearable. Get faster every year.

𝗡𝘂𝗺𝗯𝗲𝗿 𝗼𝗳 𝗠𝗲𝗱𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀
Target: as few as possible.
Every medication you're on should be earning its place. I just wrote about five commonly prescribed drugs that do more harm than good with long-term use. Bring your full medication list to every appointment. Ask: "Do I still need this?" Deprescribing is one of the most powerful and underused tools in medicine.
ꟷꟷꟷ

Thirteen numbers. Most available through cheap bloodwork and simple tests. Get them once or twice a year. Here's what I want you to understand: these numbers don't just tell you where you are. They tell you where you're heading. A fasting insulin of 8 today becomes diabetes in five years. An ApoB of 120 today becomes a heart attack in ten. An hs-CRP of 3 today means your arteries are inflamed right now — regardless of how healthy you feel. The standard annual physical checks a fraction of these. It was designed to find disease that's already there. This panel finds the disease that's coming — years before it arrives.

What gets measured gets improved. Optimize with the foundation I write about every week on this platform:
Zone 2 cardio plus resistance training 3-4 times per week. High-protein whole-food nutrition. Sleep 7-9 hours — non-negotiable. Morning sunlight. Stress management. And the targeted supplements I've covered in detail — creatine, magnesium, CoQ10, D3+K2, glycine, omega-3, psyllium husk.
The breakthroughs coming in the next decade — gene editing for cholesterol, cellular reprogramming, senolytics that clear senescent "zombie" cells driving inflammation and aging, GLP-1 drugs rewriting metabolic medicine — will be most powerful for people who've already built the metabolic foundation to receive them.

The future of medicine is personalized. But it starts with knowing your numbers today. Print this list. Book the bloodwork. Own the data. Prevention isn't passive. It's the most aggressive thing you can do for the decades ahead. open.substack.com/pub/afshine/p/…

An American @POTUS just told Israel to lower its sword.
@realDonaldTrump on his 80th birthday. With the enemy cornered.
Half the Jewish world feels betrayed today.
I don't.
And if you feel abandoned, confused, even gutted — hear me first: you're not naïve. You're paying attention. I feel it too.
I'm just not going to stop there. Let me tell you what history is going to say about this moment. 2/6
For forty years, American presidents talked tough on Iran and did almost nothing.
Red lines drawn in disappearing ink. The mullahs learned that U.S. threats expire faster than milk.
Trump broke the pattern. He didn't speak — he struck.
He battered the IRGC's command and shattered the myth that Iran was untouchable. That myth was Iran's most powerful weapon. He took it.
For the first time in a generation, the regime is bargaining from fear instead of swagger.
That is not a small thing. That is the deepest wound Iran's empire has suffered in forty years.

An open letter to @TheLancet from an Iranian-Jewish cardiologist.
Today, one of the world's most prestigious medical journals published a campaign to suspend the Israeli Medical Association from the World Medical Association — the body founded after WWII to ensure physicians would never again be weaponized by political ideology.
I'm a cardiologist. I'm an Iranian Jew who grew up under a regime where medicine was subjugated to the state.
What The Lancet just did is a disgrace to my profession.
Here's what they published — and what they deliberately left out. 2/5
What The Lancet didn't mention:
The World Medical Association itself opposes this suspension. The WMA stated explicitly that suspending members because of their governments' actions would undermine its ability to promote medical ethics globally.
The Israeli Medical Association has advocated for humanitarian aid into Gaza, demanded protections for hospitals, and called these accusations "false or contested claims presented as facts." The IMA is a professional medical body — not a branch of the Israeli government.
Hamas systematically used hospitals as military infrastructure — tunnel entrances, command centers, weapons storage. Extensively documented. One of the gravest violations of medical neutrality that exists.
The Lancet's campaign says nothing about it.

1/7
I'm a cardiologist. I'm also an Iranian Jew who grew up under a regime that promised equality for the people.
I stand with @elonmusk.
And @BernieSanders, @AOC, and politicians like NYC Mayor Zohran Mamdani are wrong. Not just politically wrong. Historically, economically, and provably wrong.
Here's why — with the receipts. 2/7
This week @SpaceX created over 4,000 new millionaires in a single day. Engineers. Technicians. Hourly workers. People who built rockets that land themselves — rewarded because the company they helped build became enormously valuable.
Bernie Sanders responded by attacking the man who made it happen.
So let's compare.
Elon's companies injected $338 billion into the U.S. economy over 2021-2025. $110 billion in wages. $46 billion in taxes. $182 billion in supplier spending. Over 200,000 jobs. Launch costs down 90%. Internet to a billion people who had none.
Every dollar reinvested. No dividends. No extraction.

Post 1/5
I'm a cardiologist. Let me tell you about the bravest and most reckless experiment in the history of medicine.
In 1984, a 32-year-old junior doctor in Australia walked into his hospital laboratory on a Tuesday morning, picked up a glass beaker containing one billion live bacteria suspended in beef broth, and drank it.
He told no one. Not his wife. Not his ethics committee. Not his hospital.
He had a theory that the entire global medical establishment had been treating one of the most common diseases on earth incorrectly for nearly a century.
He had run out of other ways to prove it.
His name was Barry Marshall. This is the story almost nobody tells you — and the reason I think about him every day in my own practice. 2/5
In 1979, a quiet pathologist named Robin Warren was looking at stomach biopsy slides at the Royal Perth Hospital when he noticed something impossible. Spiral-shaped bacteria, alive and active, living on the stomach lining.
Every textbook said the same thing: nothing survives in the stomach. Hydrochloric acid strong enough to dissolve metal. Bacteria could not colonize that environment. Every professor said so. Every pathologist who'd ever seen something strange on a slide had assumed contamination.
Warren kept looking. He kept finding them. For three years, almost no one in the hospital would listen.
In 1981, a 30-year-old trainee named Barry Marshall rotated through his department. They biopsied a hundred patients together. Every patient with a duodenal ulcer had the bacteria. Every single one.
Marshall presented the findings at the 1983 Royal Australian College of Physicians meeting. He proposed that these bacteria — later named Helicobacter pylori — caused most peptic ulcers. The disease the world had been calling a stress disorder for decades was an infection. Curable with two weeks of antibiotics.
The room laughed at him.
Senior gastroenterologists had built careers on the stress theory. The pharmaceutical industry had just launched H2 blockers — headed by Tagamet, soon to be the best-selling drug on earth. Acid-suppressing drugs would peak at $6 billion per year. Telling that industry their products treated the symptoms of an infection curable with $30 of antibiotics was professionally suicidal.

I'm a cardiologist. I've held dying hearts in my hands in the cath lab at 3 AM. And I need to tell you something that changes everything about how we prevent heart attacks.

For decades, the entire field was built on one target: lower LDL cholesterol. Statins save lives — that's settled science. But too many of my patients did everything right — took their statins, hit their numbers, lived clean — and still ended up on my table with a ruptured artery.

We were treating the smoke while the fire kept burning.
The fire is inflammation. And the evidence is now overwhelming.

The CANTOS trial proved it first — lowering inflammation independent of cholesterol reduced cardiac events. But the newer data is what keeps me up at night.

AI-enhanced CT angiography can now detect inflamed arteries by measuring changes in the fat surrounding your coronary vessels — the perivascular fat attenuation index. Higher inflammation in the fat around even one artery independently predicts cardiac death. When multiple arteries show inflammation, the risk multiplies dramatically — even in patients whose cholesterol looks perfect.

This isn't theoretical. This is measurable. Right now. On a scan you can get this month.

Low-dose colchicine — a drug that's been around for centuries for gout — is now FDA-approved specifically for reducing cardiovascular events. It works by quieting the inflammatory cascade that destabilizes the plaque sitting in your arteries. A pill that costs pennies is saving lives the statins couldn't reach.

And the next wave is already in Phase 3 trials. Ziltivekimab — an IL-6 inhibitor — targets the central inflammatory pathway driving atherosclerosis. Phase 2 data showed a 90% reduction in hsCRP. The ZEUS cardiovascular outcomes trial is enrolling now, with results expected late 2026 into 2027. If positive, anti-inflammatory therapy will become standard in managing heart disease alongside lipid-lowering. The era of inflammation-targeted cardiology is arriving.
But it goes deeper than drugs. AI is now predicting heart failure and cardiac events 5+ years before symptoms — integrating CT imaging, electronic health records, and genetic data with accuracy that jumps far beyond traditional risk calculators.

And polygenic risk scores — a simple genetic test that flags inherited cardiovascular risk — are now formally recognized as a risk-enhancing factor in the 2026 ACC/AHA guidelines. A single blood draw can reveal risk that's been silently building since birth. Decades before the first chest pain.

Here's what this means for you right now — today:
Ask your doctor for a high-sensitivity CRP test. It's cheap, routine, and measures the systemic inflammation that standard cholesterol panels completely miss. You can have perfect LDL and inflamed arteries that are quietly preparing to rupture.
If your hsCRP is elevated, discuss low-dose colchicine with your physician. It's FDA-approved for exactly this.
Push for a coronary CT angiography with AI plaque and inflammation analysis if you have risk factors. This isn't the stress test your parents got. This is 3D visualization of your actual arteries — with AI quantifying not just how much plaque you have, but what kind it is and whether the surrounding tissue is inflamed.
Consider polygenic risk score testing — especially with a family history of early heart disease. It's now guideline-supported.

And the foundation that never changes: move daily, eat real food, sleep 7-9 hours, manage stress, and know your numbers — ApoB, Lp(a), hsCRP, fasting insulin.
I left Iran as a child with nothing. I rebuilt everything in a country that gave me the freedom to become a physician. I've spent twenty years watching patients get second chances.

The ones who haunt me aren't the ones who died on my table. They're the ones who survived but never acted on what the science was telling them — years before the event that didn't have to happen.

You can have perfect cholesterol and still have a heart attack. Inflammation plus genetics can drive plaque rupture in arteries that look "fine" on a standard panel.
The myth that normal cholesterol means you're safe has cost more lives than I can count.

We now have the tools to detect the fire — not just the smoke. AI to see it. Genetics to predict it. Drugs to quiet it. And the ancient basics — movement, real food, sleep, purpose — to prevent it from starting.

Prevention is the new cure. And the science to make it real is no longer coming.
It's here. If you want to read more:

I'm a cardiologist. I'm 58 years old. I was born in Iran, exiled as a child, and rebuilt my life from nothing in a country that owed me nothing.
It took me decades to understand what I'm about to tell you.
I learned some of these lessons in medical school. Some in the cath lab at 3 AM. Some from Rumi and Rabbi Nachman. Some from patients who taught me more about living in their final hours than I learned in four years of residency.
I wish someone had given me these words at twenty. No one did. So I'm giving them to you now. 2/5
The less you say, the more your words carry. I've spent thousands of hours in ICU waiting rooms. The person everyone turns to is never the one who talked most. They're the one who waited, listened, and spoke only when it mattered. Silence isn't emptiness. It's precision. The Kotzker Rebbe said: not everything that is thought should be said. Not everything said should be written. Not everything written should be published.
Don't take everything personally. Most people are far too consumed by their own fears and insecurities to think about you as much as you imagine. I spent years believing the world was scrutinizing my every misstep. It wasn't. It was busy with its own. The freedom that comes from truly understanding this is one of the most underrated gifts of getting older.
What you focus on becomes your reality. The Kabbalists mapped this centuries ago — where your attention goes, your life follows. I've watched patients with terrible prognoses outlive patients with better numbers, because one group focused on what they could still build and the other focused on the verdict. Your mind is not a passenger in your life. It's the steering wheel.

I'm a cardiologist. I see it every day in clinic. Heart failure. Clogged arteries. Early cognitive decline. Fatty liver progressing toward cirrhosis. Patients on five medications who are still losing ground.All driven by the same metabolic storm. A drug just dropped Phase 3 data that has the entire field paying attention. And this isn't just another weight-loss shot.
Retatrutide.
Eli Lilly's triple agonist.
The data is unlike anything we've seen in cardiometabolic medicine. Let me walk you through exactly why — and what it means for the future of heart disease. 2/5
The mechanism is what separates this from everything on the market.
Ozempic activates one receptor — GLP-1. Suppresses appetite. ~15% weight loss. Zepbound activates two — GLP-1 and GIP. Better appetite suppression, better insulin sensitivity. ~22%. Retatrutide activates three — GLP-1, GIP, and glucagon. 28% average body weight loss. Roughly 70+ pounds.
That third receptor changes the game entirely. Glucagon activation doesn't just reduce appetite. It switches your metabolism to actively burn stored fat as fuel. Ketone bodies rose 2-3x in the trial — confirming a cellular fuel-source shift.
Appetite down. Energy expenditure up. Dual attack on the disease from both directions.
Even the lowest dose — 4mg — already outperformed Wegovy's full dose. At the highest dose, some patients actually had to stop the drug because they lost too much weight.
That has never happened before with an obesity medicine at this scale. The challenge shifted from losing weight to maintaining a healthy new normal.

I'm a cardiologist. I'm also an Iranian Jew.
I don't talk about this often on here. But today I want to tell you something about who I am — and why I see the world the way I do.
My family's roots in Persia stretch back roughly 2,700 years. We were among the oldest continuous Jewish communities on earth. Synagogues in Isfahan. Scholars in Shiraz. Merchants and physicians in Tehran. We survived every empire that rose and fell across that ancient land.
And then, in a single generation, most of it vanished.
After 1979, the Jewish community of Iran — once 100,000 strong — collapsed. My family was among those who left. We carried our faith, our language, our poetry, our medical traditions, and the memory of a home that no longer wanted us.
We came to America. 2/5
I love this country with a depth I think only immigrants fully understand.
Not the abstract love of someone born into abundance. The fierce, protective, almost desperate love of someone who has seen what happens when the foundations that guarantee liberty shift beneath your feet.
America gave my family something Persia could not: the freedom to build without fear. The freedom to practice medicine. To pray openly. To raise children in safety. To write, to speak, to dream — without looking over our shoulders.
Every opportunity I've had — UCLA, my cardiology practice, my books, this platform — exists because America kept its promise to a family that arrived with almost nothing.
That kind of debt doesn't expire. And that kind of gratitude doesn't stay quiet when you feel the foundations being tested.

1/5 I'm a cardiologist. After twenty years of treating hearts, I've arrived at a truth that changed how I practice medicine.
The health of your brain is inseparable from the health of your heart. They rise or fall together.
And cognitive decline doesn't begin the day you forget a name or misplace your keys.
It begins years earlier — the moment movement quietly disappears from your daily life.
This isn't a metaphor. It's a biological mechanism. And once you understand it, you'll never think about sitting the same way again. 2/5
Your brain is the most adaptive organ in your body. It constantly scans for demand.
When you sit for hours — at a desk, in a car, on a couch — your nervous system receives a very clear message: demand is low. The body isn't moving. The brain reasons it doesn't need to maintain full processing power.
So it begins to dial things down.
Neuroplasticity decreases. BDNF — the brain's natural growth fertilizer — drops. Neural connections get pruned. The hippocampus, prefrontal cortex, and other regions governing memory, focus, and decision-making slowly shrink.
Here's the insight that changes everything: your brain isn't breaking down from damage.
It's adapting. Rationally. To reduced demand.
The same way a muscle atrophies when it isn't loaded, your brain withdraws investment when it isn't challenged by physical movement. And the adaptation happens terrifyingly fast — a few weeks of prolonged sitting can shift the trajectory.

.@elonmusk just told Forbes: "The future of medicine will be digital. If you know what to program into that synthetic RNA strand, you can basically cure anything."
The internet is divided. Half think it's visionary. Half think it's hype.
I'm a cardiologist. I already prescribe RNA-based medicine to my patients. In my office. Today.
Let me show you exactly where we are — what's already real, what's coming, and what's still theoretical. No hype. No fear. Just the clinical truth. 2/5
What's already here — right now, in my practice:
Inclisiran. Brand name Leqvio. An siRNA injection I administer to patients twice a year. It silences the PCSK9 gene in the liver — the gene responsible for producing a protein that raises LDL cholesterol.
Two shots a year. LDL drops roughly 50%. No daily pills. No monthly injections. The drug enters your liver cells, finds the specific mRNA that codes for PCSK9, and destroys it. Your liver simply stops making the protein that was raising your cholesterol.
FDA-approved. Now cleared as first-line monotherapy as of last year. Sustained LDL reduction documented out to nearly 7 years. Over 60,000 patients across 30+ clinical trials.
That's not digital medicine as a metaphor. That's literally a synthetic RNA strand programmed to silence one gene. Musk's language is engineering shorthand for what I already do in clinic.

I'm a cardiologist. Here's why I recommend men take 5 mg of tadalafil — Cialis — every single day.
Not for ED. Not for performance.
I take it for the same reason every serious longevity physician I respect does: to protect my cardiovascular system, my brain perfusion, and my endothelial health at the most fundamental level.
This drug — famous for all the wrong reasons — has quietly become one of the most powerful tools in preventive cardiology. And the data is now too strong for me to keep quiet about it. 2/5
Here's what tadalafil actually does.
PDE5 is the enzyme that breaks down cGMP — the molecule that tells your smooth muscle to relax and your blood vessels to dilate. By blocking PDE5, tadalafil produces system-wide vasodilation: better blood flow to the heart, brain, lungs, kidneys, muscles — every organ downstream of your vascular tree.
Unlike Viagra, which lasts 4-6 hours, tadalafil's effects last up to 36 hours. A low daily dose keeps plasma levels stable around the clock.
Now here's why this matters for your heart.
Endothelial dysfunction — the failure of that thin layer of cells lining 60,000 miles of your blood vessels — is the earliest, most predictive marker of cardiovascular disease. It precedes plaque, heart attacks, and strokes by years. By the time most patients reach my office, the damage is done.
Tadalafil directly improves endothelial function. It reduces arterial stiffness. It shows anti-fibrotic effects on the heart muscle in preclinical models. It's already FDA-approved for pulmonary arterial hypertension.
Most patients come to me when something has already broken. I'm treating the pipes before they clog.

I'm a cardiologist. I have spent twenty years watching cholesterol destroy arteries, trigger heart attacks, and kill people I care about.
Today, Eli Lilly presented data that may begin to end that era.
VERVE-102. A single infusion. One dose. It uses base editing to permanently turn off the PCSK9 gene in your liver.
Presented today at the European Atherosclerosis Society Congress:
88% reduction in PCSK9.
62% reduction in LDL cholesterol.
Sustained up to 18 months.
No treatment-related serious adverse events.
One infusion. Not daily pills you forget to take. Not monthly injections. One dose — and your cholesterol may stay low for the rest of your life. 2/5
Let me explain why this is so profound.
There are rare people born with naturally occurring loss-of-function variants in the PCSK9 gene. Their bodies produce very little PCSK9 protein. Their LDL cholesterol stays naturally low throughout their entire lives. They almost never develop coronary heart disease.
VERVE-102 is designed to give that same genetic protection to anyone who needs it. One infusion. Permanently edits the gene. Mimics what nature already does in the luckiest among us.
Lilly acquired the technology for roughly $1 billion and is preparing to launch Phase 2 trials by the end of this year.
Heart disease remains the number one killer on earth. Every moment of LDL exposure matters for your lifetime cardiovascular risk. A one-time treatment that durably eliminates excess LDL could prevent millions of heart attacks that haven't happened yet.
This is not incremental. This is a paradigm shift.

I'm a cardiologist. I need to tell you something that will change how you think about heart disease screening.
The standard approach — EKGs, echocardiograms, stress tests, basic labs, a cholesterol panel — misses approximately 75% of people who will go on to have a heart attack, stroke, or cardiac death.
These tests check how your heart functions. They do not check what's quietly building inside your arteries.
And the arteries are where plaque accumulates silently for decades before you feel the first chest pain. By then, the event is already happening.
Most heart attacks aren't caused by severely blocked arteries. They're caused by soft, inflamed, rupture-prone plaque that no stress test on earth will detect.
There is a better way. I use it in my practice. Here are the tests that actually find the disease before it finds you. 2/5
Coronary CT Angiogram with AI plaque composition analysis.
This is the single most important upgrade in cardiac prevention in the last decade.
It visualizes your coronary arteries in 3D, quantifies your total plaque burden, and — critically — uses AI to tell me exactly how much plaque is soft, lipid-rich, and rupture-prone versus stable and calcified.
Why this matters: non-obstructive plaque causes most cardiac events. Your arteries can look "clear enough" on a stress test while harboring the exact kind of soft plaque that ruptures without warning. This test finds it.
Medicare just started reimbursing AI-enhanced plaque analysis. If you're over 40 with any risk factors, ask for this by name: coronary CT angiogram with plaque composition analysis.
If soft plaque is found early, we can stabilize and often reverse it with aggressive statins, PCSK9 inhibitors, GLP-1s, and lifestyle intervention. I've seen it happen in my practice.
