    Abstract:
    The aim of this study was to determine the diagnostic and therapeutic strategies after myocardial infarction and to examine variations in medical and surgical practice with respect to the severity of disease, status of the hospital and patients' characteristics. The method used was a prospective study with follow-up at 30 days and 18 months. The subjects came from an exhaustive cohort of all patients admitted to hospital for myocardial infarction during the month of April 1991 in 57 public and private hospitals in the Rhone-Alps region (n = 311). The patients were identified after admission by consulting physicians of the Department of Social Security. The study included all patients with acute myocardial infarction with at least two of the three usual diagnostic criteria (prolonged, constrictive chest pain, enzyme increases and electrocardiographic changes). The study excluded patients who were dead before arrival at hospital. The parameters analysed included the clinical management, use of echocardiography, exercise stress testing, myocardial scintigraphy, coronary angiography, thrombolysis, angioplasty and coronary bypass surgery in the first 30 days after admission. The severity of infarction was assessed by seven clinical, enzymatic and electrocardiographic criteria by physicians from the Department of Social Security (pain, syncope, shock, left ventricular dysfunction, elevation of CPK > 1000 IU, anterior or extensive necrosis, arrhythmias). The mortality rate of this cohort was calculated from hospital statistics and then by enquiring in the town halls of the region. The demographic features of the cohort were marked by a predominance of men (69.5%) and a relatively high mean age (69 years; 23% over 80 years). Complementary investigations were used with the following frequencies: echocardiography, 61.1%; coronary angiography, 26.4%; exercise stress testing 22.8%; myocardial scintigraphy, 5.5%.(ABSTRACT TRUNCATED AT 250 WORDS)
