Well, if I was going to test this, the first thing that comes to mind is to test primates for ASCVD. If possible, I would study wild vs. captive primates, too. I dug around a little. There have been a few studies on primates. I couldn't find much out about them. However, if wild primates eating their normal diets get it, then I would tend to think it was "normal." If they don't, then I would say it wasn't normal. It does seem we have a limited lifespan. Maybe ASCVD is the preferred method to limit it. For me personally, I would much prefer ASCVD over cancer or Alzheimer's.
I did run across this while searching for studies: atherosclerosis-journal article 0021-9150(74)90008-2. That's pretty interesting. They were able to initiate atherosclerosis in primates by increasing levels of carbon monoxide.
I supplied a paper here below the vid, and we already know, chimps don't suffer ASCVD as humans do with much higher cholesterol, hence one main point from the vid discussing the issue.
