REFERRAL PATTERNS AND EXERCISE RESPONSE IN THE REHABILITATION OF FEMALE CORONARY PATIENTS AGED GREATER-THAN-OR-EQUAL-TO-62 YEARS

Gender-related differences in cardiac rehabilitation referral patterns and response to an aerobic conditioning program were examined in 226 hospitalized older coronary patients (aged greater-than-or-equal-to 62 years). Overall, the outpatient cardiac rehabilitation participation rate in this population was 21%. Older women were less likely to enter cardiac rehabilitation than were older men (15 vs 25%; p = 0.06), despite similar clinical profiles. This was explained primarily by a greater likelihood of primary physicians to strongly recommend cardiac rehabilitation to men. Before conditioning, women who entered cardiac rehabilitation were less fit than were men; peak oxygen consumption was 18% lower in women (16 +/- 5 vs 20 +/- 5 ml/kg/min; p = 0.02). However, both groups improved aerobic capacity similarly in response to a 12-week aerobic conditioning program, with maximal oxygen consumption increasing by 17% in women and by 19% in men. Thus, older female coronary patients are less likely to be referred for cardiac rehabilitation, despite a similar clinical profile and improvement in functional capacity from the training component.
