Risk factors and late recurrence of angina following myocardial revascularization.
To assess the influence of risk factors on the recurrence of angina several years after myocardial revascularization, 316 patients were studied. We report that 249 patients obtained relief of angina from coronary bypass surgery and remained free of angina up to 4 years later. The remaining 67 patients experienced initial relief of angina 1 year following bypass surgery and then, subsequently, redeveloped angina 4 years postsurgery. There was no statistical difference in any risk factor between patients who remained free of angina after myocardial revascularization and those who developed angina. Of the total 316 patients, 79% were free of angina 4 years after coronary bypass surgery.
