Comparison of the clinical profile and outcome of women and men in cardiac rehabilitation.
Few data are available regarding the outcome of women in cardiac rehabilitation. To determine whether women differ from men in clinical profile and outcome, 225 consecutive patients were prospectively evaluated in an urban, multidisciplinary, exercise-based cardiac rehabilitation program. Among the 51 women (age 56 +/- 10) and 174 men (age 54 +/- 10), most were: white (84%), married (64%), employed (63%), had had myocardial infarction or revascularization, or both (66%), and traveled less than 10 miles to the program (92%). Risk profiles revealed obesity in 48% (mean Metropolitan Relative Weight = 124 +/- 22%), hypertension in 47%, smoking in 23%, diabetes in 16%, and mean cholesterol of 236 +/- 45 mg/dl. Compared with men, more women were nonwhite, unemployed, unmarried, hypertensive or diabetic (p less than 0.0001) and had higher cholesterol (p less than 0.01). Compliance rates were similar for women (51%) and men (63%) (p = not significant). Univariate predictors of program noncompliance differed between women and men. Initial exercise capacity was less for women than for men, but both groups achieved a similar training effect. Women increased their exercise time by 31% and peak METs by 30%, whereas men showed a 21% increase in exercise time and 16% increase in peak METs achieved (p less than 0.001). Thus, in this cardiac rehabilitation program, women have a less favorable risk factor profile and differ from men with regard to baseline demographics and predictors of program completion. Women, however, have similar rates of compliance and achieve the same improvement in functional capacity with training.
