What are the long-term effects of coronary artery bypass surgery for stable angina?
Based on the Veterans Administration Coronary Artery Bypass Surgery Cooperative Study Group, the ten-year follow-up of survival and myocardial infarction in the randomized Coronary Artery Surgery Study showed that the prognostic value of angiographic indices of coronary artery disease from the Coronary Artery Surgery Study was improved. Additionally, the prognostic value of a coronary artery jeopardy score was improved, and the influence of aortocoronary bypass surgery on survival was noted. Thus, the long-term effects of coronary artery bypass surgery for stable angina include improved survival and myocardial infarction rates, improved prognostic value of angiographic indices of coronary artery disease, and improved prognostic value of a coronary artery jeopardy score.
