title: [The clinical features of myocardial infarct via "normal" coronary angiography. The experience of the Instituto Nacional de Cardiología].
abstract: The end-point of our study was to find clinical differences between patients with myocardial infarction and evident obstructions in coronary angiography, and patients without coronary obstructions. In a 10 years follow-up period, 48 patients with diagnosis of myocardial infarction and normal coronary arteries by angiography (group A) where admitted al hospital. We compared this group with 80 patients (group B), randomly selected from all patients with myocardial infarction and evident obstructions in coronarography. Patient age at the ischemic event, familiar history of ischemic heart disease or sudden death, obesity, drug habits, contraception drugs use, and history of migraine and Raynaud's phenomenon were pointed out. Thirty patients from group A were admitted with acute myocardial infarction, and we also analysed in these patients prodromal symptoms, precipitating factors, AMI localisation, serum enzymatic levels, rhythm and/or conduction disturbances, clinical condition, treatment and new ischemic events. Group A patients showed lower age-average, smoking habit, prodromal symptoms and serum CPK levels. They have better ventricular performance parameters and a greater incidence of women. The only different risk factor for ischemic heart disease between both groups was smoking.
