Cardiac rehabilitation for the treatment of women with chest pain and normal coronary arteries.
OBJECTIVE
To explore cardiac rehabilitation (CR) as a treatment for psychological and physiological morbidity in women with chest pain and normal coronary arteries (cardiac syndrome X).


METHODS
Sixty-four women aged 57.3+/-8.6 years (mean +/- SD) with cardiac syndrome X were randomly assigned to an 8-week phase III CR exercise program or symptom monitoring control. All women completed the Hospital Anxiety and Depression Scale, Health Anxiety Questionnaire, and Short Form-36 before and after intervention and at the 8-week follow-up. CR patients underwent physical assessment before and after CR.


RESULTS
After CR, patients demonstrated improved symptom severity (2.0+/-0.8 vs 1.26+/-1.1, P=0.009), Hospital Anxiety and Depression Scale depression score (8.0+/-3.4 vs 6.4+/-3.1, P=0.04), total Health Anxiety Questionnaire score (12.0+/-5.5 vs 9.5+/-6.0, P=0.008), health worry (4.5+/-3.1 vs 3.52+/-2.4, P=0.025) and interference (2.4+/-1.8 vs 1.6+/-1.8, P=0.004), SF-36 physical functioning (53.1+/-20.4 vs 62.3+/-23.9, P = 0.006), energy (36.3+/-20.7 vs 49.8+/-19.1, P<0.001), pain (49.9+/-20.7 vs 58.1+/-22.9, P=0.028), and general health (48.8+/-17.9 vs 57.6+/-17.0, P=0.01) not found among the control women. Improvements were maintained at follow-up. CR patients showed significant improvements in Shuttle Walk Test performance (326.8+/-111.0 vs 423.6+/-133.2 m, P<0.001), diastolic blood pressure (84.7+/-9.4 vs 79.7+/-7.3 mm Hg, P=0.007), and body mass index (29.1+/-6.0 vs 28.4+/-6.17 kg/m2, P=0.003).


CONCLUSIONS
An 8-week phase III CR program improves exercise tolerance, quality of life, psychological morbidity, symptom severity, and cardiovascular risk factors in women with cardiac syndrome X.
