The main pumping chamber of the heart ages differently in men and women, according to a new magnetic resonance imaging (MRI) study published online in the journal Radiology. Researchers said the findings may support different treatment approaches for men and women with heart disease.
The mass of the left ventricle—the chamber of the heart that pumps blood throughout the body—is a predictor of cardiovascular events. The ventricle walls may thicken from having to work harder to pump blood in the presence of high blood pressure or other conditions.
Studies have shown both increases and decreases in left ventricular mass with age. Many of these studies have been cross-sectional, or focused on one point in time, and based on comparisons between the young and old, which doesn't account for different lifestyles and other historical factors. But for the new study, researchers were able to assess long-term changes in the same people by acquiring a baseline cardiac MRI and then comparing it with another taken at a later date.

Other conditions, like exercise. And no, I'm not kidding. This is what an ER physician told me once, and the very fit people actually have a lower chance of surviving a heart attack because more of the heart can die due to lack of blood than couch potatoes. On the other hand, couch potatoes are much more likely to have a heart attack and present no symptoms before a hear attack.
Low blood flow to heart can sometimes be detected via exercise. For example, there was one person that had a heart attack due to blockage during a group bike ride (he's very fit). But if he was a couch potato, maybe that blockage would be become apparent until it was 100% and then bad things happen. (Yes, he's fine now)
Anyway, predictor for cardiovascular events is not only thickness of the heart. It's things like ejection fraction (how efficient the heart is), rest heart rate, family history, BMI, and other things.

>exercise a lot, more likely to die from heart attack
>don't exercise, more likely to have a heart attack
Dammit, I would like to file a complaint with reality, this game is simply unfair. Who the hell playtested this shit anyway?

We are the testers.
Sadly there's no in-game interface to the bug report system, you have to quit the game and then report the bug. Oh and game save's disabled.
