title: [The evaluation of the diagnostic usefulness of the clinical picture, electrocardiography and enzymes in the initial presentation of an acute myocardial infarct].
abstract: Medical data of 181 patients, affected by confirmed acute myocardial infarction, were reviewed to evaluate the initial clinical, electrographic and radiological data, and the first CPK test. Eleven patients went to the emergency department without chest pain (6.1%). The percentage of patients with oppressive chest pain was 73%, being of thoracic localization in 86.4%, 20%. Related to effort; 47.1% referred; and 92.9% of more than 30 mins. duration. 35.3% had normal blood pressure. Only 5 patients (2.8%) had normal EKG, the S-T segment elevation being the most frequent alteration (71.3%). 89.5% of patients had sinusal rhythms; 20.4% were bradycardic. 58.6% had normal levels of CPK at the first test. We concluded that EKG is the most important test in diagnosing acute myocardial infarction; it being very rarely normal. The clinical data are coadjuvant, while isolated initial CPK had not value.
