N2 - Angina pectoris (AP) is a treatable symptom that is associated with mortality and decreased quality of life. The prevalence and predictors of AP 1 month after a myocardial infarction (MI), a time when additional treatments might be offered, have not been described. We prospectively enrolled 2,094 patients with MI from 19 centers in the United States and evaluated angina symptoms 1 month after discharge with the Seattle Angina Questionnaire. Multivariable logistic regression analysis was performed to identify patient and treatment characteristics associated with 1-month AP. At 1 month, 571 patients (27.3%) had AP. Women (odds ratio [OR] 1.37, 95% confidence interval [CI] 1.09 to 1.74), younger patients (OR 1.33 per 10-year increment, 95% CI 1.20 to 1.47), those with previous coronary artery bypass (OR 1.47, 95% CI 1.05 to 2.05), smokers (OR 1.35, 95% CI 1.09 to 1.77), and those who developed postinfarct AP during the index hospitalization (OR 1.85, 95% CI 1.20 to 2.65) were more likely to have AP at follow-up. In contrast, patients who were treated with coronary artery bypass surgery during their index admission were less likely to have AP at 1 month (OR 0.5, 95% CI 0.33 to 0.77). The strongest correlate was the frequency of AP before patients' MI. Compared with those without AP before MI, those with AP <1 time per week (OR 1.86, 95% CI 1.45 to 2.41), weekly (OR 4.24, 95% CI 3.09 to 5.82), and daily (OR 6.12, 95% CI 3.62 to 10.3) were more likely to have AP 1 month later. In conclusion, >1 in 4 patients reported AP 1 month after an MI.
