Fetal monitoring with computerized ST analysis during labor: a systematic review and meta-analysis.

BACKGROUND: Computerized ST analysis of fetal electrocardiography (ECG) combined with cardiotochography (CTG) has been introduced for intrapartum monitoring and is the prevailing method when ST analysis (STAN®) is used. OBJECTIVE: To assess the evidence that computerized ST analysis during labor reduces the incidence of fetal metabolic acidosis, hypoxic ischemic encephalopathy, cesarean section, instrumental vaginal delivery or the number of instances where fetal scalp blood sampling is used as compared with CTG only. METHODS: Search of PubMed, Cochrane Library, EMBASE, Web of Science, CINAHL and CRD databases. SELECTION CRITERIA: CTG only compared with CTG + computerized ST analysis. DATA COLLECTION AND ANALYSIS: Studies were assessed using pre-designed templates. Meta-analyses of included randomized controlled trials were performed using a random effects model. RESULTS: Risk ratio for cord metabolic acidosis with STAN® was 0.96 [95% confidence interval (CI) 0.49-1.88]. Risk ratio for cesarean sections or instrumental vaginal deliveries for fetal distress was 0.93 (95%CI 0.80-1.08) and for fetal scalp blood sampling 0.55 (95%CI 0.40-0.76). Encephalopathy cases were not assessed due to their low incidence. CONCLUSIONS: There is not enough scientific evidence to conclude that computerized ST analysis reduces the incidence of metabolic acidosis. Cesarean sections and instrumental vaginal deliveries due to fetal distress or other indications are the same, regardless of method, but STAN® reduces the number of instances which require scalp blood sampling.

Stress reduction prolongs life in women with coronary disease: the Stockholm Women's Intervention Trial for Coronary Heart Disease (SWITCHD).

BACKGROUND: Psychosocial stress may increase risk and worsen prognosis of coronary heart disease in women. Interventions that counteract women's psychosocial stress have not previously been presented. This study implemented a stress reduction program for women and investigated its ability to improve survival in women coronary patients. METHODS AND RESULTS: Two hundred thirty-seven consecutive women patients, aged 75 years or younger, hospitalized for acute myocardial infarction, coronary artery bypass grafting, or percutaneous coronary intervention were randomized to a group-based psychosocial intervention program or usual care. Initiated 4 months after hospitalization, intervention groups of 4 to 8 women met for a total of 20 sessions that were spread over a year. We provided education about risk factors, relaxation training techniques, methods for self-monitoring and cognitive restructuring, with an emphasis on coping with stress exposure from family and work, and self-care and compliance with clinical advice. From randomization until end of follow-up (mean duration, 7.1 years), 25 women (20%) in the usual care and 8 women (7%) in the stress reduction died, yielding an almost 3-fold protective effect of the intervention (odds ratio, 0.33; 95% CI, 0.15 to 0.74; P=0.007). Introducing baseline measures of clinical prognostic factors, including use of aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, calcium-channel blockers, and statins into multivariate models confirmed the unadjusted results (P=0.009). CONCLUSIONS: Although mechanisms remain unclear, a group-based psychosocial intervention program for women with coronary heart disease may prolong lives independent of other prognostic factors.

Daily stress and social support among women with CAD: results from a 1-year randomized controlled stress management intervention study.

Financial strain predicts recurrent events among women with coronary artery disease.

BACKGROUND: Although a number of epidemiological studies have found an association between socioeconomic status (SES) indices such as income and education and coronary morbidity and mortality, few have looked at health consequences arising from actually experiencing financial shortcomings. The objective of the present study was to examine whether financial strain predicts recurrent coronary artery disease (CAD) events among women with established CAD. METHODS: Two hundred two women (mean age 62+/-9 years) hospitalized for an acute coronary event were followed over a period of 3.5 years. Demographic, socioeconomic, lifestyle-related, psychosocial and biological characteristics were obtained by means of questionnaires and clinical examination. Data on recurrent cardiac events were collected from the Swedish discharge and death registers. RESULTS: Women experiencing financial strain over the past year had an increased risk for recurrent events, i.e. the combination of all-cause mortality, new acute myocardial infarction and unstable angina pectoris during the follow-up with an unadjusted hazard ratio (HR) of 3.2 (95% CI 1.6-6.6), and a HR of 2.76 (95% CI 1.02-7.50) after controlling for education, household income, age, cohabiting status, inclusion diagnosis and rehabilitation therapy. Adjustment for potential mediators, i.e. psychosocial factors, lipids, diabetes mellitus, smoking, body-mass index, blood pressure, physical activity, alcohol consumption, participation in other cardiac rehabilitation programs did not alter the results significantly. CONCLUSIONS: Financial strain was a predictor for recurrent events among women with CAD, independently of commonly used SES indicators such as education and household income. Future studies will have to explore the mechanism behind this association.

Work and marital status in relation to depressive symptoms and social support among women with coronary artery disease.

BACKGROUND: Work and marital status have been shown to be associated with health outcome in women. However, the effect of employment and marriage on psychosocial functioning has been studied predominantly in healthy subjects. We investigated whether work and marital status are associated with depressive symptoms, social support, and daily stress behavior in women with coronary artery disease (CAD). METHODS: Data of 105 women with CAD and of working age were analyzed. General linear models were used to determine the association between work and marital status and depressive symptoms, social support, and daily stress behavior. RESULTS: Women who were working at the time of measurement had lower levels of depressive symptoms (7.0 +/- 1.2 vs. 12.1 +/- 0.9, p < 0.01) and higher levels of social support (21.6 +/- 1.0 vs. 18.9 +/- 0.7, p = 0.03) than the nonworking women, whereas marital status was not related to any of the outcome variables. Results were similar after adjusting for potential confounders, that is, age, education, self-reported health, and risk factors for CAD. There was no significant interaction between marital status and working status on depressive symptoms, social support, or daily stress behavior. CONCLUSIONS: In women with CAD, all <65 years of age, after a cardiac event, patients working had lower levels of depressive symptoms and a better social integration than those not working, regardless of reason for being nonemployed. Daily stress behavior, depression, and social support did not differ between cohabiting and not cohabiting women. Future interventions should take into consideration that women with CAD who are unemployed may have a higher risk for depression and social isolation and, therefore, poor clinical outcomes.

Self-rated health and vital exhaustion, but not depression, is related to inflammation in women with coronary heart disease.

Poor subjective well-being has been associated with increased coronary heart disease (CHD) morbidity and mortality in population-based studies and with adverse outcomes in existing CHD. Little is known about the mechanisms responsible for this association, but immune activity appears to be a potential pathway. Despite the growing evidence linking immune activity to subjective feelings, very few studies have examined patients with CHD, and the results are conflicting. We examined consecutive women patients hospitalized for acute myocardial infarction, and/or underwent percutaneous transluminal coronary angioplasty or coronary artery bypass grafting. We assessed depression, vital exhaustion, and self-rated health by questionnaires. Circulating levels of high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), and interleukin-1 receptor antagonist (IL-1ra) concentrations were determined. After controlling for potential confounding factors there was a significant positive correlation between IL-6 levels and vital exhaustion and poor self-rated health. The association between hsCRP and vital exhaustion and self-rated health was borderline significant. In contrast, the correlations between psychological factors and IL-1ra levels were weak and non-significant, as were the correlations between inflammatory markers and depression. Similar relationships between the inflammatory markers and the measures of psychological well-being were obtained when the latter ones were categorized into tertiles. In conclusion, inflammatory activity, assessed by IL-6 and hsCRP levels, was associated with vital exhaustion and self-rated health in CHD women. These findings may provide further evidence for a possible psychoneuroimmune link between subjective well-being and CHD. Our observations also raise the possibility that a cytokine-induced sickness response in CHD may be better represented by constructs of vital exhaustion and self-rated health than of depression.

Social relations in women with coronary heart disease: the effects of work and marital stress.

BACKGROUND: Studies have previously shown that psychosocial stress, related to both work and family, is associated with the increased risk of coronary heart disease (CHD) morbidity and mortality. The objective of this study was to examine how social relations are affected by marital stress and work stress in a population-based sample of Swedish women with CHD. METHOD: Data was obtained from the Stockholm Female Coronary Risk Study, comprising 292 women aged 65 years or younger, with a mean age of 56 (SD=7) years admitted for an acute event of CHD and examined 3-6 months after hospitalization. Marital and work stress was assessed using the Stockholm Marital Stress Scale and the Swedish version of the Karasek demand-control questionnaire, respectively. Condensed versions of the Interview Schedule for Social Interaction (ISSI) and of Interpersonal Support Evaluation List (ISEL) were used to assess social relations and social support. RESULTS: Marital stress was associated with less social integration (P<0.001), less appraisal support (P<0.001), a lower sense of belonging (P<0.01) and less tangible support (P<0.01) even after controlling for work stress. Adjustment for age, socioeconomic status (education and occupational status) did not alter these results significantly. Work stress did not show statistically significant effects on any of the measured social relations. CONCLUSION: The present study showed that marital stress influenced women's social relations. These results suggest that marital stress needs to be further investigated not only as an independent but also as an interactive risk factor for women with CHD.

Depressive symptoms in relation to marital and work stress in women with and without coronary heart disease. The Stockholm Female Coronary Risk Study.

OBJECTIVE: The aim of this study was to investigate the effect of marital and job stress on depressive symptoms in middle aged women with coronary heart disease (CHD) and healthy women who were cohabiting and currently working. METHOD: Data were obtained from the Stockholm Female Coronary Risk (FemCorRisk) Study, a population-based case-control study, comprising all women aged 65 years or younger who were admitted for an acute event of CHD between 1991 and 1994. For each patient, an age-matched healthy control was recruited. Marital stress was assessed by a structured interview developed in our research laboratory and work stress by the Karasek demand-control questionnaire. Depressive symptoms were measured by a questionnaire derived from Pearlin et al. [J. Health Soc. Behav. 22 (1981) 337], which was validated by the Beck Depression Inventory. RESULTS: Depressive symptoms were twice as common in women with as in women without coronary disease: Marital stress was statistically significantly associated with depressive symptoms, even after controlling for age, educational level, menopausal status, body mass index (BMI), sedentary lifestyle, cigarette smoking and severity of heart failure symptoms. In both groups, depressive symptoms increased with increasing exposure to marital stress in a graded fashion. Work stress was not associated with depressive symptoms after multivariate adjustment. CONCLUSIONS: Marital stress but not work stress is independently related to depressive symptoms in women. Women with coronary disease react similarly to marital stress as healthy women, but depart from a higher level of depression, which may be explained by their poorer health status.
