Coronary Interventions and Diagnostics

In the face of an increasing incidence of multivessel disease and worse preoperative left ventricular performance, operative risk has decreased. The decrease in morbidity and mortality is attributed to improved myocardial protection. The 5 and 10 year survival rates for patients with chronic stable angina are 92.3 and 77.3 percent respectively. Reports indicate that ejection fraction is the best indicator of late survival. Controlled studies such as the Seattle Heart Watch and the European Cooperative Study show significantly higher 5 year survival rates with surgical treatment. Results in patients with left main stenosis and poor left ventricular function show improvement in operative risk and medium-term survival. Evidence exists that coronary artery surgery favorably influences the annual rate of fatal myocardial infarction and sudden death. The number of candidates for reoperation has gradually increased with time; the 5 year survival rate for reoperation is 89.2 percent.
