The long-term followup results of coronary artery angioplasty.
The long-term efficacy of PTCA for the relief of angina pectoris and myocardial ischemia has been firmly established. Coronary angiography reveals sustained anatomic improvement in the majority, especially if PTCA is repeated in those patients who developed restenosis. Successful PTCA is associated with a low incidence of cardiac events such as myocardial infarction, elective cardiac bypass surgery, or death during late followup. The majority of patients are completely free of angina and demonstrate objective improvement with exercise testing. Patients with multivessel disease, if properly selected, may derive nearly as much long-term benefit from PTCA as patients with single-vessel disease.
