The way I read that article the Americans had the more developed arteriosclerotic plaques and the Asians had fatty streaks. I'll post for those that don't want to read the entire article although I recommend the read.
"KOREAN WAR AUTOPSY CONNECTION
It was during the Korean War that doctors thought they had discovered the “real” cause of heart disease. Autopsies on young soldiers killed in action showed well-developed atheromas (arteriosclerotic plaques) in their coronary and carotid arteries. Additionally, fatty streaks of the intima of their arteries, arterioles, and heart muscle existed. While similar fatty streaks were observed in dead Korean and Chinese soldiers, the well-developed atheromas found in American soldiers were conspicuously absent. Analysis of
the plaques found showed it was a saturated fat (palmitic acid). The atheromas also contained quite a lot of a familiar waxy substance—better known as cholesterol."
