𝗕𝗥𝗘𝗔𝗞𝗜𝗡𝗚: The American Heart Association just dropped their 2026 dietary guidelines—and they're game-changing for cardiovascular health.

Here are the 9 features of a heart-healthy diet you need to know 🧵👇

𝗞𝗘𝗬 𝗜𝗡𝗦𝗜𝗚𝗛𝗧: Heart disease doesn't start in your 50s—it starts in the womb.

The guidelines emphasize eating heart-healthy from pregnancy through old age. Your childhood diet predicts your adult cardiovascular risk.

Start early. Stay consistent.

🚨 𝗕𝗥𝗘𝗔𝗞𝗜𝗡𝗚 from #ACC2026: Two major RCTs just challenged everything we thought about Impella pumps in cardiac care.

The results? Surprising.
The implications? Massive.

A thread on what every cardiologist needs to know 🧵👇 𝗧𝗥𝗜𝗔𝗟 #𝟭: 𝗖𝗛𝗜𝗣-𝗕𝗖𝗜𝗦𝟯
🇬🇧 UK's answer to a $500M question

300 patients with:
• Severe LV dysfunction (EF ≤35%)
• Extensive CAD (BCIS-JS ≥8)
• Complex PCI planned

Randomized: Impella CP vs. Standard Care

What happened? 👇

Pulmonary hypertension (PH) associated with left heart disease (LHD) is the most prevalent form of PH, making up 65% to 80% of all cases.
Despite its high morbidity and mortality, it remains vastly under-investigated, with no specific pharmacologic therapies approved to date.

The root cause?
Elevated left atrial pressure (LAP) from left heart dysfunction is transmitted back to the pulmonary veins.
This triggers endothelial dysfunction, microvascular barotrauma, and maladaptive vascular remodeling, ultimately stiffening the pulmonary arteries.

The 2026 ACC/AHA Dyslipidemia Guidelines are officially here!
Replacing the 2018 guidelines, these new updates bring major shifts in risk assessment, novel lipid markers, and cholesterol targets.
Here are the most salient features you need to know. 🧵👇

Out with the PCE, in with the PREVENT equations! 🧮
The guidelines now recommend the AHA PREVENT-ASCVD equations (instead of the older Pooled Cohort Equations) to calculate 10- and 30-year risk for primary prevention in adults aged 30 to 79.

🆕 HOT OFF THE PRESS in JAMA (Feb 23, 2026)
“Does This Patient Have Volume Overload?”
The 2026 Rational Clinical Examination (40 studies, 11,490 patients).
In an obese patient with mixed wet/dry signs… how do you actually decide?
Thread with the key LRs + real-world case 👇

#MedTwitter #POCUS #JAMA #HeartFailure 2/14
78F | A-fib | BMI 38
Left-leg cellulitis + edema, SpO2 86% RA.
Albumin 1.7 (looks “dry”/third-spacing)
CXR: increased vascular markings + BNP 107 (looks “wet”)
Diuresed 2 days → weight ↓1 kg but Cr 1.6 → 3.2.
Has volume overload been confirmed?

🚨 The 2026 AHA/ACC PE guidelines changed how we think about pulmonary embolism.
Not just new treatments — a new clinical framework.
Say goodbye to “massive vs submassive.”
Meet A–E PE Clinical Categories 🧵👇 2/16
Old PE stratification mixed BP, RV strain, biomarkers, and outcomes into blunt labels.
Result:
• Stable-looking patients who crashed
• Overtreatment of others
The 2026 guideline fixes this by focusing on physiology & trajectory.
