Neurocognitive functioning and improvement in quality of life following participation in cardiac rehabilitation.
We investigated the relationship between neurocognitive functioning and quality of life/self-perceived health status (QOL) among cardiac rehabilitation (CR) patients to determine whether level of neurocognitive functioning is related to baseline QOL and improvement following CR. CR patients (n = 35) were given a neurocognitive screening before participation in CR, and also completed a behavioral inventory (SF-36) before and after CR to measure QOL associated with medical illness. At baseline, CR patients obtained relatively low SF-36 scores compared with published norms, and as reported previously, demonstrated inferior neurocognitive performance compared with healthy controls. Furthermore, neurocognitive performance was strongly positively correlated to SF-36 scores. Significant improvements were evident on many of the SF-36 subscales following rehabilitation. These improvements were relatively greater among SF-36 indexes of physical health status compared with SF-36 indexes of mental health status. Baseline neurocognitive performance also correlated strongly to the degree of improvement in SF-36 scores following rehabilitation. These findings indicate a strong relationship between baseline neurocognitive functioning and QOL before CR, and the degree to which QOL improves following this intervention.
