High PAI-1 precedes a first heart attack, indicating blood coagulation as a primary risk factor ahajournals.org/doi/10.1161/01…
PAI-1 is not only elevated in the elderly but also significantly induced in a variety of pathologies associated with the process of aging academic.oup.com/cardiovascres/…
A null mutation in the gene that encodes PAI-1 is associated with *7 years* longer lifespan. This is in an Amish community. They also have no diabetes. science.org/doi/10.1126/sc…
PAI-1 is greatly reduced in trained athletes vs sedentary
Overweight/Obesity, Smoking, and Heavy Alcohol Consumption Are Important Determinants of Plasma PAI-1 Levels in Healthy Men sciencedirect.com/science/articl…
Linoleic acid enhances the secretion of plasminogen activator inhibitor type 1
A single dose of aspirin cuts PAI-1 levels in half
Weight loss leads to significant decreases in PAI-1
I'll spare you the rest - yes, there's a lot more - but it's clear that PAI-1 and its role in blood coagulation are clear health risk factors.
Mainstream medicine doesn't look at it though.
The very low PAI-1 activity in Kitavans may explain some of their apparent freedom from cardiovascular disease and probably relates to their extreme leanness.

As 2025 comes to a close, here's what you need to know about setting your 2026 health goals:
92% of adults have poor metabolic health.
And most are focused on the wrong metrics.
Here's the deal:
The most powerful predictor of chronic disease risk isn't your BMI, your weight, or your cholesterol.
It's your waist size. And you can measure it right now at home with nothing but a piece of string.
The Formula: Measure your waist at its widest point (around your belly button, not your pants size, since these are fake). That number should be no more than half your height.
Example: At 70 inches tall, your maximum reasonably healthy waist is 35 inches.
The number 1 cause of chronic disease, including heart disease, many cancers, Alzheimer's, dementia gout and (almost) anything you care to name, is poor metabolic health.
Let me explain:
Poor metabolic health is most commonly visible to the naked eye based on 2 factors:
-Excess body fat (being over fat, no matter the BMI)
-Low muscle mass (being under muscled, again, no matter the BMI)
The official term for poor metabolic health is insulin resistance.
My shortcut is this: the opposite of poor metabolic health = being lean and fit.
