Why the study?
Does direct surgical myocardial revascularization improve symptoms, survival, and ventricular function in patients with coronary insufficiency?
Does direct surgical myocardial revascularization improve symptoms, survival, and ventricular function in patients with coronary insufficiency?
Direct surgical myocardial revascularization is effective in relieving angina, prolonging life in patients with severe proximal lesions, and improving ventricular function.
An analysis has been made of the results of 5,600 surgical procedures for coronary insufficiency. Data suggest not only that angina is relieved in a high proportion of patients, but that life is prolonged in patients with widespread or critical proximal lesions and that ventricular function is improved by competent grafts. It follows that angiographic assessment and surgical treatment have high priorities in the management of patients with coronary Insufficiency.
