Tag: Cardiac risk

According to the American College of Cardiology and American Heart Association, a surgical procedure is considered high risk if it carries a greater than 5% estimated risk of a major 30-day cardiac event, such as a heart attack or death. Understanding **what percentage is considered high risk surgery** involves evaluating both the type of procedure and the individual patient's health status.

According to the American Heart Association, intermediate-risk procedures are associated with an estimated cardiac risk of 1–5% of major events. This classification is a critical component of preoperative planning, helping to determine what is an intermediate risk for surgery and the appropriate evaluation steps.
