Gender differences in psychosocial outcomes of psychotherapy trial in patients with depression and coronary artery disease.

INTRODUCTION: The biological and psychosocial risk profile differs between women and men with coronary artery disease (CAD). Depressive symptoms and Vital Exhaustion (VE) predict an unfavourable course of CAD. The secondary analysis of the SPIRR-CAD trial offered the possibility to examine gender as exposure variable of the clinical and psychological situation at baseline and in a variety of psychosocial measures as outcomes. METHODS: In this trial, 450 men (78.9%) and 120 women (21.1%) with CAD (age ≤ 75 y), with mild to moderate depression (scoring ≥8 on the HADS), were randomized to usual care with or without a stepwise psychotherapy intervention. Beside clinical measures exhaustion and other indicators of depressive symptoms were collected at baseline and 18-month follow up. RESULTS: Men had more signs and symptoms of heart disease at baseline, whereas women had higher psychosocial burden (e.g. negative affect). Women were more likely to live alone, had lower educational levels and employment rates and higher levels of depression and exhaustion. The psychotherapy intervention differed as a function of gender: In women, VE decreased from 29.4 ± 8.1 to 22.1 ± 11.7 in the intervention group (IG) and from 29.2 ± 8.2 to 25.1 ± 11.3 in the control group (CG). In men VE decreased from 23.3 + -10.8 to 21.2 ± 9.7 in the IG and from 23.6 ± 10.7 to 19.3 ± 11.3 in the CG (time x intervention x gender; F = 4.97; p = .026). DISCUSSION: Women had a higher psychosocial burden than men. VE compared to other rating instruments of depressive symptoms suggested a stronger response to the intervention in women. VE may help to understand gender differences in psychotherapeutic treatment studies of CAD. ISRCTN: 76240576; clinicaltrials.gov.      «
