Actually you're right that meats (fatty acids) are a large cause of AS, there are a few clarifications I'd like to make. Apparently plants contain their own sterols which compete with cholesterol for sites on lipoproteins, which means that while plant-based diets could be useful in treating AS. However causing heightened atherosclerosis is only an issue for fatty meats and lean meats such as chicken don't have this much of an impact on cholesterol, and even then it's not because they contain more cholesterol per se[https://pmc.ncbi.nlm.nih.gov/articles/PMC6024674/ ctrl+f "The importance of dietary cholesterol in CVD continues to be discussed as shown in a recent review in which the authors concluded that although eggs constitute a main source of cholesterol, their role in CVD is tenuous" this is about eggs but extends to anything with high cholesterol] but rather precursors to it. Essentially cholesterol is synthesized from fats and you shouldn't eat fats a lot.[https://pubmed.ncbi.nlm.nih.gov/15927927/ ctrl+f "lean red meat is low in saturated fat, and if consumed in a diet low in SFA is associated with reductions in LDL-cholesterol in both healthy and hypercholesterolemia subjects."]
