[Effect of angina in the week before myocardial infarction on long-term cardiovascular morbidity and mortality after hospital discharge].
The occurrence of angina in the week preceding myocardial infarction is associated with a reduction in cardiovascular complications in the acute phase. However, little is known about it relationship with prognosis after hospitalization (e.g., cardiovascular death and the development of heart failure or ischemic cardiomyopathy). The study included 290 consecutive patients admitted for a first myocardial infarction: 107 (36.9%) had preceding angina while 183 did not. Those with a history of ischemic cardiomyopathy of more than 1 week or structural cardiopathy were excluded. There was no difference in baseline characteristics between the two groups. Moreover, there was no difference in the rates of cardiovascular complications after hospital discharge: cardiovascular death (7% vs. 12.6%; P=.3), heart failure (7.4% vs. 11.6%; P=.2), and myocardial ischemia, including myocardial infarction and unstable angina, requiring hospitalization (41.2% vs. 31.3%; P=.3). The occurrence of angina in the week before a first myocardial infarction did not influence cardiovascular complications after hospital discharge (odds ratio = 0.75 [0.51-1.11]; P=.15).
