Retrospective analysis of information on 283 patients with myocardial infarction (186 males and 97 females) showed that 64.7% of persons who had suffered from the disease for the first time and 88.6% of those with recurrent myocardial infarction had a history of anginose pain. Exacerbation of angina pectoris had occurred in 56.0% of patients with no previous myocardial infarction and in 71,4% of those with recurrent infarction. A preinfarction state was encountered in primary and recurrent myocardial infarction with equal frequency (in 73.0 and 74.7% of cases, respectively). Nitroglycerin efficacy diminishes in the month preceding myocardial infarction. During exacerbation of angina pectoris, 39.8% of patients who had no previous myocardial infarction and 73.8% of those with a history of the disease applied for medical advice.
