Telephone-based peer support intervention to reduce depressive symptoms in women with coronary heart disease, a randomized controlled trial in Germany.

Depressive symptoms in patients with coronary heart disease (CHD) predict adverse outcomes regarding e.g. cardiovascular complications. We trained women with CHD to support female peers through telephone-based counseling and tested whether depressive symptoms can be reduced, and perceived social support can be improved by the intervention over six months. 108 women with CHD and self-reported depressive or anxiety symptoms were included in a randomized controlled trial. The intervention group was offered immediate telephone-based peer support for six months, while the waiting list control group received the intervention with a 6-months delay. Primary outcomes were depressive symptoms and perceived social support immediately after the intervention period and at 6-months-follow-up. 40% of the women made use of the peer support. During the first six months, both groups showed a reduction in depressive symptoms (IIG: t(169) = -1.79, p = .08; WCG: t(169) = -2.76, p = .007) and a significant improvement in social support (IIG: t(175) = 3.54, p < .001; WCG: t(175) = 3.36, p < .001). We found no significant group × time interactions. There was no influence of telephone-based peer support on depressive symptoms and social support. We discuss potential causes for both lack of specific treatment effects and the general improvement over time in both groups.

Cross-Sectional and Longitudinal Associations of Systolic Blood Pressure With Quality of Life and Depressive Mood in Older Adults With Cardiovascular Risk Factors: Results From the Observational DIAST-CHF Study.

OBJECTIVE: Although diagnosed arterial hypertension and antihypertensive medication usually have an adverse impact on quality of life, recent studies suggest that actual blood pressure may be positively related to better well-being. However, data in older patients with cardiovascular risk factors are lacking, for whom such an association may be of particular relevance. METHODS: In 1300 adults aged 50 to 85 years with cardiovascular risk factors (51.5% men, mean age = 65.7 ± 8.2 years) participating in an observational study, we performed standardized measurements of blood pressure and assessed quality of life and depressive symptoms at baseline and 1-year follow-up using the Short Form-36 (SF-36) and the Hospital Anxiety and Depression Scale (HADS). RESULTS: Bivariate analysis demonstrated that systolic blood pressure was associated with higher SF-36 mental component summary scores (r = 0.100, p < .001) and reduced HADS depression (r = -0.082, p = .003). Multivariate regression models adjusting for age, sex, and disease severity confirmed that higher systolic blood pressure significantly predicted both better mental quality of life (ß = 0.070, p = .012) and less depressive mood (ß = -0.083, p = .003) at baseline, independently of antihypertensive medication and diagnosed hypertension. Moreover, the beneficial effects of baseline systolic blood pressure remained stable for both summary components of the SF-36 as well as HADS depression at 1-year follow-up. All results remained unchanged, when limiting the analyses to the 1072 patients with diagnosed hypertension. CONCLUSIONS: In older adults with cardiovascular risk factors, higher systolic blood pressure readings are independently related to better quality of life and fewer depressive symptoms in both cross-sectional and longitudinal settings, although the magnitude of the effect sizes is typically small.

A Stepwise Psychotherapy Intervention for Reducing Risk in Coronary Artery Disease (SPIRR-CAD): Results of an Observer-Blinded, Multicenter, Randomized Trial in Depressed Patients With Coronary Artery Disease.

BACKGROUND: Depression predicts adverse prognosis in patients with coronary artery disease (CAD), but previous treatment trials yielded mixed results. We tested the hypothesis that stepwise psychotherapy improves depressive symptoms more than simple information. METHODS: In a multicenter trial, we randomized 570 CAD patients scoring higher than 7 on the Hospital Anxiety and Depression Scale-depression subscale to usual care plus either one information session (UC-IS) or stepwise psychotherapy (UC-PT). UC-PT patients received three individual psychotherapy sessions. Those still depressed were offered group psychotherapy (25 sessions). The primary outcome was changed in the Hospital Anxiety and Depression Scale-depression scores from baseline to 18 months. Preplanned subgroup analyses examined whether treatment responses differed by patients' sex and personality factors (Type D). RESULTS: The mean (standard deviation) depression scores declined from 10.4 (2.5) to 8.7 (4.1) at 18 months in UC-PT and from 10.4 (2.5) to 8.9 (3.9) in UC-IS (both p < .001). There was no significant group difference in change of depressive symptoms (group-by-time effect, p = .90). Preplanned subgroup analyses revealed no differences in treatment effects between men versus women (ptreatment-by-sex interaction = .799) but a significant treatment-by-Type D interaction on change in depressive symptoms (p = .026) with a trend for stronger improvement with UC-PT than UC-IS in Type D patients (n = 341, p = .057) and no such difference in improvement in patients without Type D (n = 227, p = .54). CONCLUSIONS: Stepwise psychotherapy failed to improve depressive symptoms in CAD patients more than UC-IS. The intervention might be beneficial for depressed CAD patients with Type D personality. However, this finding requires further study. TRIAL REGISTRATION: www.clinicaltrials.gov NCT00705965; www.isrctn.com ISRCTN76240576.

Socioeconomic factors in coronary artery disease - Results from the SPIRR-CAD study.

Low socio-economic status (SES) has been associated with an increased coronary risk in Western countries. All stress experiences are more pronounced in low SES patients with stress emanating from problems with family, job, or money. The SPIRR-CAD study offered an excellent opportunity to examine these risk factors in German speaking mildly and medium depressed patients. In the SPIRR CAD study, a German multi centre randomized clinical trial of 450 male and 120 female coronary patients, we examined the standard and psychosocial risk factor profiles in relation to SES, as assessed by educational level. All differences in risk factors between low and high SES were in the inverse direction. Of standard risk factors, only smoking was socially graded and more common in low SES. Of psychosocial factors and emotions, exhaustion showed the strongest and most consistent inverse social gradient, but also anger, anxiety and depression were socially graded. The findings suggest that in German patients, as in other national groups, social gradients in CHD risk are considerable. They can be ascribed to both psychosocial and to standard risk factors. In the present two years follow-up, the prospective significance of psychological and social risk factors was analyzed showing that emotional factors played an important role, in that low and high SES patients differed in the expected direction. However, the differences were not statistically significant and therefore firm conclusions from follow up were not possible. TRIAL REGISTRATION: ISRCTN 76240576; NCT00705965.
