title: Exercise performance, physical activity, and health-related quality of life in participants with stable angina.
abstract: We compared exercise performance, daily physical activity, and health-related quality of life in 115 participants with stable angina and 441 controls without coronary artery disease or stable angina. Participants with stable angina had shorter 6-min walk distance (P = .003), and lower total leisure-time physical activity (P = .003) than the controls. Group differences in these measures remained (P < .05) after adjusting for age, race, current smoking, diabetes, hypertension, and obesity. Participants with stable angina also had lower health-related quality of life for physical function (P < .001), general health (P = .002), and vitality (P < .001), but group differences did not remain (P > .05) after adjustment for comorbid conditions. Participants with stable angina have impaired exercise performance and reduced daily physical activity. Thus, they are prime candidates for exercise interventions designed to improve daily physical activity and exercise performance.
