The study compared percutaneous revascularization and conservative treatment for severe lesions in secondary branches of epicardial arteries to evaluate their effectiveness in preventing cardiovascular events.
After analyzing data from 679 lesions over an average follow-up of 22.2 months, there were no significant differences in outcomes between the two treatment methods, including rates of cardiovascular death and nonfatal myocardial infarction.
Key factors linked to increased event occurrence included diabetes, history of acute myocardial infarction, and longer lesion length.
