We recently reported11 on the benefits of formal cardiac rehabilitation in 268 consecutive elderly patients ≥ 65 years of age (mean age, 70 ± 4 years; 76% men). In this cohort, following rehabilitation, small, but statistically significant, improvements were noted in obesity indexes, including total weight (−1%; p < 0.05), body mass index (−1%; p < 0.05), and the percentage of body fat (−6%; p < 0.001). Although total cholesterol and triglyceride levels had nonsignificant minor improvements following rehabilitation, there were significant improvements in high-density lipoprotein (HDL) cholesterol (+3%; p < 0.01), total cholesterol/HDL ratio (−4%; p < 0.01), and fasting glucose level (−4%; p < 0.01). Estimated exercise capacity improved markedly (+34%) following cardiac rehabilitation. There were also demonstrable improvements in validated scores for anxiety, depression, and somatization by 40%, 40%, and 33%, respectively (all p < 0.0001), as well as for overall QOL score (+17%; p < 0.0001) following cardiac rehabilitation. Although elderly patients typically have significantly lower hostility scores and lower prevalence of hostility than the younger patients, hostility scores still improved modestly (−19%; p = 0.06) following cardiac rehabilitation, but elderly patients with high hostility scores at baseline had more marked improvements following rehabilitation (hostility score, −48% [p < 0.001]; QOL, + 23% [ p < 0.001]).
