Drug therapy for acute myocardial infarction at Hospital de Clínicas de Porto Alegre
Abstract
OBJECTIVE: To determine the prescription rates of thrombolytics, aspirin, betaadrenergic antagonists and angiotensin-converting-enzyme inhibitors during the acute
phase of the infarction, and to determine the prescription rates of aspirin, betaadrenergic antagonists, and angiotensin-converting-enzyme inhibitors for secondary
prophylaxis.
MATERIALS AND METHODS: The prescription rates were determined by reviewing the medical records of all patients whose diagnosis of acute myocardial infarction
was made at Hospital de Clínicas de Porto Alegre from January 1996 to February 1997.
RESULTS: We identified 100 patients, with a mean age of 63 ± 13 years, 58% men and 89% white. The drug prescription rates in the acute phase were: 41% for
thrombolytics, 97% for aspirin, 81% for beta-adrenergic antagonists and 38% for angiotensin-converting-enzyme inhibitors. The secondary prophylaxis prescription
rates were: 71% for aspirin, 68% for beta-adrenergic antagonists and 45% for angiotensin-converting-enzyme inhibitors.
CONCLUSION: The prescripition rates forthe drugs listed above are still bellow the ideal ranges, although they are comparable to the rates reported in the medical
literature.
