Characteristics of a contemporary population with angina pectoris. TIDES Investigators.
To characterize a contemporary, nonhospitalized population with angina pectoris, data were obtained from a geographically diverse cohort of 5,125 outpatients with chronic stable angina cared for by 1,266 primary care physicians between September and November of 1990. Diagnosis was based on history supported by evidence for coronary artery disease (coronary angiography, old myocardial infarction, or an abnormal stress test, either alone or in combination). The mean age of the patients was 69 years and 53% were women. Seventy percent had > 1 associated illness and 64% took > 1 cardiovascular drug. Median angina frequency was approximately 2 episodes/week and increased angina frequency (p < 0.0001) was associated with decreased overall feeling of well-being. Although effort angina was present in 90% of patients, 47% also had rest angina and 35% had mental stress-evoked angina. Female gender (relative risk [RR] 1.09; 95% confidence interval [CI] 1.02 to 1.16), concomitant illness (RR 1.17; CI 1.09 to 1.25), and pharmacotherapy (RR 1.14; CI 1.07 to 1.22) were associated with excess risk for rest angina. Younger age (RR 1.30; CI 1.20 to 1.41), female gender (RR 1.16; CI 1.07 to 1.26), concomitant illness (RR 1.13; CI 1.03 to 1.24), and pharmacotherapy (RR 1.28; CI 1.15 to 1.93) were associated with excess risk for mental stress angina. These data suggest that contemporary outpatients with angina are frequently women and elderly patients with high rates of associated illness, rest, and mental stress-related angina.
