The clinical course, early prognosis and coronary anatomy of subendocardial infarction

摘要: The following prospective study was undertaken to observe the clinical course, early prognosis and coronary anatomy of patients with subendocardial infarction. Subendocardial infarction defined as typical chest apin (greater than 15 minutes), serum enzyme elevation persistent 48 hours) new T wave inversion and/or S-T segment depression in absence pathologic Q waves. Fifty consecutive were defined, followed a manner subjected arteriography. A prior history unstable angina found 33 (66 per cent); 22 (44 cent) had significant dysrhythmias during acute hospital phase, seven (14 evidence mild left ventricular failure. Coronary arteriography demonstrated lesions 75 cent narrowing at least one vessel) all 50 patients, 30 (60 having either double- or triple-vessel disease. Follow-up (mean 10.6 months) revealed that (30 stable angina, 23 (46 only 12 (24 remained free angina. Of 28 medically treated group, transmural infarctions developed six (21 died (3 cent). We conclude is symptomatically an entity, associated severe artery disease and, by incidence myocardial Therefore, these require in-hospital monitoring, careful follow-up consideration for
