Oh! Short stature, mountainous country near the equator - means the least gravity affecting their circulation! Natural heart-healthy situation!
You might be joking, but higher altitude also means less oxygen, which translates to reduced oxidation and less risk of cancer.

I'm on my cellphone so I don't have the paper on hand, but there was a big study where they compared lung cancer rates in different geographic areas and found that the highest cancer incidence was at sea level, whereas the lowest was at higher elevations. They tried controlling for other obvious variables but elevation was unquestionably the best explanation.

Oxidation may explain plaque in arteries.

Short heart-to-brain distance may also predict an ability to handle high G-forces as a fighter pilot. https://fightersweep.com/1411/agsm/
Do astronauts have better hearts? Was this studied in the twins experiement we saw a while ago?
