The severity of coronary artery stenosis 60% depends on which vessel is stenosed, if the stenosis is 60% of the left main artery, it is a severe stenosis, if the stenosis is 60% of other coronary vessels, it is not particularly serious. For patients with 60% coronary artery stenosis, if the stenosis of the left main artery reaches 60%, interventional treatment or surgical bypass surgery is required. If the other coronary artery stenosis is 60%, interventional or surgical bypass surgery is not required for the time being, but active secondary prevention and treatment measures for coronary artery disease are still needed to keep the condition stable and prevent further aggravation.
