[Preinfarct stenocardia and acute myocardial infarct from the viewpoint of modern coronary surgery].
The results of aorto-coronary shunting in 36 patients with preinfarction angina and of urgent direct myocardial revascularization in 17 patients with acute myocardial infarction are presented. The surgical mortality comprised 28% in the group of patients with preinfarction angina. Twenty-two patients were followed-up for 8 months to 4 years. Good results were obtained in 9 patients, satisfactory--in 7, unsatisfactory--in 4. One patient died of cardiac insufficiency 1 1/2 year after surgery. The diagnosis of preinfarction angina is a direct indication for urgent coronary angiography and aorto-coronary shunting in case suitable coronary arteries are available for anastomosing. The indications for urgent revascularization of the myocardium in cases of infarction included the inefficacy of drug therapy within 2-3 hours of its onset, an unarrested pulmonary oedema and cardiogenic shock in cases of localized proximal occlusion of the coronaries revealed by elective or urgent coronary angiography. Four patients were operated on in the state of cardiogenic shock (one of them after reversing the state of clinical death), and two patients were operated on with pulmonary oedema. All these patients (with the exception of the one with pulmonary oedema) recovered. Four patients died. The follow-up covered a period of 9 months to 3 years. Good results were obtained in 4 patients, satisfactory--in 3, unsatisfactory--in 4. No late mortality cases were observed. The obtained results permit to analyse the preinfarction angina and acute myocardial infarction from the standpoint of modern coronary surgery.
