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.

How many women are adrenaline junkies? It's all fun and games to ride a motorcycle three times the speed limit, and leave the cops eating dust, but that adrenaline ages you, just like most other bad drugs.
Alright - I suppose I should be more serious. The article seems to offer some clues, at least. Men have traditionally done heavier labor than women (except during childbirth, of course) Men have traditionally also exercised more, and played more strenuous sports. All that in ADDITION to acts of derring do that dumps adrenaline into the blood stream.
So, yeah, the heart being a muscle, those who exercise it more often are going to build up the muscle. More mass leaving less volume inside the mass.

I didn't know women had hearts. I know that they regularly rip the hearts out of men and devour them, but I did not know they had hearts themselves.

I'm sorry that you have apparently been burned by someone. Though, that street is hardly a one way street. There are many men and women like that. (I. E. Heartless, Cruel, etc.) I don't call breaking up due to reasonable or even semi-arbitrary reasons as Heartless or Cruel. Though, hopefully you have already figured out it wouldn't work, before you got married.

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.

Dammit, I would like to file a complaint with reality, this game is simply unfair. Who the hell playtested this shit anyway?

For decades social justice authoritarians have been silencing any scientific findings that run counter to their narrative that "men and women are equal".
Even 60 minutes ran a segment on the vast difference between men and women being silenced in journals due to Feminism. [youtube.com]

"Studies have shown" is almost always followed by some questionable or pointless claims. I didn't even read further after the headline about differences. Tell us when you discover some (near) universal pattern rather than more group A is different than group B preliminary data.
