Unstable angina is common in our city (YAZD - IRAN), but as the patients characteristics and long term outcome are not clear, this study was performed. 100 patients with unstable angina were selected from Rahnemoon & Afshar hospitals (in Yazd) and the patients characteristics, their risk factors, in hospital course were recorded. After discharge, these patients were visited several times and any new events were recorded for one year. The mean age of the patients (47% female, 53% male) was 62.84+11.85. The frequency of hypertension, diabetes mellitus, smoking, hyperlipidemia and positive family history, was 48%, 29%, 18%, 410/u and 40% respectively. The ECG changes were ST depression > 1 mm in 48%, ST elevation > 1 mm in 17%, negative T wave in 25% and normal ECG in 10% of patients. Acute myocardial infarction occurred in 6% of patients, especially in the first week of unstable angina. Total death rate after one year was 13% and most of them were sudden deaths. Death was more common, in old age (more than 70ys), male patients (9% VS 4%) and in patients with ST depresstion > 1 mm. Recurrent unstable angina occurred in 20% of patients. Coronary artery bypass was done in 19% of patients. During a 1 year follow up of unstable angina patients in Yazd, new myocardial infarctions were seen in 6% of the patients and the mortality rate was 13%.
