What you’re saying seems untrue to the point of being disingenuous.
Op claimed that a vegan diet (a much stricter diet than “eating vegetables”) can reverse atherosclerosis to the point of not needing surgery (a much stronger claim than “is healthy”), and for that, very much yes, citation needed.
OP didn't claim a vegan diet, "plant-based" (the link even says "more plant-based") in virtually no possible definition translates to vegetarian. A full blown strawman :D
Anyway, a two minute Google search can even find some US-friendly related material (but probably someone could be able to say that Harvard is a vegan-soviet-wokist psyop, one could never know...)
"The best diet for preventing heart disease is one that is full of fruits and vegetables, whole grains, nuts, fish, poultry, and vegetable oils; includes alcohol in moderation, if at all; and goes easy on red and processed meats, refined carbohydrates, foods and beverages with added sugar, sodium, and foods with trans fat."
Four patients were placed on a vegan diet in 1977. Three of them adhered to the diet and experienced a reversal of the disease (an improvement in their symptoms), while one patient saw improvement but later switched back to a regular diet, resulting in a return of his symptoms.

In a study involving 198 patients with cardiovascular disease, 89% adhered to a plant-based diet, eliminating dairy, fish, and meat while adding oil. These adherent patients experienced only one recurrent cardiac event (a stroke), resulting in a low recurrence rate of 0.6%. In contrast, 62% of nonadherent participants experienced adverse events. This suggests that intensive counseling on plant-based nutrition can be successful in reducing cardiac events and warrants further testing in broader populations to address the cardiovascular disease epidemic.
The Nurses' Health Study: This long-term study, conducted by Harvard University, has examined the dietary habits and health outcomes of thousands of nurses over several decades. It has consistently shown the health benefits of vegetable consumption
The Framingham Heart Study: Another long-running study, the Framingham Heart Study, has looked at heart disease risk factors and health outcomes in a large population. It has demonstrated the positive effects of a diet rich in vegetables on heart health
Plant-based Diets Improve Cardiac Function, Cognitive Health
The EPIC (European Prospective Investigation into Cancer and Nutrition) Study: This study involves multiple countries in Europe and has provided significant evidence of the health benefits of plant-based diets, including lower risks of cancer and chronic diseases.
The Dietary Approaches to Stop Hypertension (DASH) Trial: While not exclusively focused on vegetables, the DASH trial emphasizes the importance of a diet rich in fruits and vegetables for managing blood pressure and overall health
