[Prognostic significance of angina pectoris before myocardial infarction]

The AA analysed the incidence of previous angina to myocardial infarction (PA) (42.3%) and post myocardial infarction angina (PMIA) (46.39%) in 97 patients that survived the acute phase of myocardial infarction, all discharged from the CCU of the Funchal's Hospital Center Cardiological Department (Madeira Island), whose 25 of them (26.8%) presented both. They met 14 positive Treadmill tests in the 30 patients that were submitted to sub-maximal protocols. They concluded that the presence of PA and positive treadmill tests can identify a patient group with increased risk of PMIA, suggesting that patients with PA have also an increased isquemic risk.
