Relationship between psychosocial status, diabetes mellitus, and left ventricular systolic function in patients with stable multivessel coronary artery disease

The Importance of DS-14 and HADS Questionnaires in Quantifying Psychological Stress in Type 2 Diabetes Mellitus

Background and Objectives: The comorbid association between type 2 diabetes mellitus (T2DM) and a psychological profile characterized by depression and/or anxiety has been reported to increase the risk of coronary heart disease (CAD), the most striking macrovascular complication of diabetes. The purpose of the present study was to quantify anxiety, depression and the presence of type D personality, and to correlate the scores obtained with cardiovascular risk factors and disease severity in diabetic patients. Materials and methods: The retrospective study included 169 clinically stable diabetic patients divided into two groups: group 1 without macrovascular complications (n = 107) and group 2 with CAD, stroke and/or peripheral vascular disease (n = 62). A biochemical analysis and an assessment of psychic stress by applying the Hospital Anxiety and Depression Scale (HADS)and the Type D scale (DS-14) to determine anxiety, depression and D personality scores were done in all patients. Statistical analysis was made using SPSSv17 and Microsoft Excel, non-parametric Kruskal-Wallis and Mann-Whitney tests. Results: Following application of the HAD questionnaire for the entire group (n = 169), anxiety was present in 105 patients (62.2%), and depression in 96 patients (56.8%). Group 2 showed significantly higher anxiety scores compared to group 1 (p = 0.014), while depression scores were not significantly different. Per entire group, analysis of DS-14 scores revealed social inhibition (SI) present in 56 patients (33%) and negative affectivity (NA) in 105 patients (62%). TheDS-14 SI score was significantly higher in group 2 compared to group 1 (p = 0.036). Type D personality, resulting from scores above 10 in both DS-14 parameter categories, was present in 51 patients of the study group (30%). There was a direct and significant correlation (r = 0.133, p = 0.025) between the Hospital Anxiety and Depression Scale-Anxiety (HAD-A) score and the LDL-c values. Conclusions: The results of this study demonstrated that more than a half of patients with diabetes had anxiety and/or depression and one third had Type D personality, sustaining that monitoring of emotional state and depression should be included in the therapeutic plan of these patients. New treatment strategies are needed to improve the well-being of diabetic patients with psychological comorbidities.

Social Support, Unstable Angina, and Stroke as Predictors of Depression in Patients With Coronary Heart Disease

BACKGROUND

Depression is known to adversely affect coronary heart disease patients in western countries; however, no study of social support and depression has been conducted in the Chinese population.

OBJECTIVE

The aim of this study was to investigate the predictors of depression in patients with coronary heart disease.

METHODS

Between January and December 2015, a cross-sectional sample of 105 Taiwanese patients from cardiology units completed a demographic and clinical characteristics questionnaire, Enhancing Recovery in Coronary Heart Disease Social Support Inventory, and Patient Health Questionnaire-9.

RESULTS

Thirty-nine percent of the participants reported low social support, and 61.0% had depression symptoms. Eight factors predicted depression. Social support was significantly and adversely correlated with depression (r = -.481, P < .01). The other 7 factors were positively correlated with depression: age (r = .212, P < .05), reported monthly income of less than US $600 (F = 4.98, P = .001), lack of exercise (F = 3.75, P = .027), history of stroke (t = -2.45, P = .016) and kidney disease (t = -2.41, P = .018), unstable angina (F = 3.56, P = .031), and groin puncture (F = 3.27, P = .042). A hierarchical regression model explained 43.7% of the variance in depression.

CONCLUSION

Social support, unstable angina, and stroke may be important predictors of depression in patients with coronary heart disease. These findings help clinical staff to understand physical and mental health problems in cardiovascular patients. Thus, we suggest that early depression prediction and sufficient social support can help patients to face their disease and thus improve depression and health care quality.

Depression in Cardiovascular Patients in Middle Eastern Populations: A Literature Review

Cardiovascular disease (CVD) is increasing in Middle Eastern countries. Depression is associated with increased morbidity and mortality rates among cardiovascular (CV) patients. Early detection of and intervention for depression among CV patients can reduce morbidity and mortality and save health care costs. Public information on mental health care needs of Arab CV patients living in Middle East regions is scattered and limited. This literature review surveyed and summarized research studies to learn what is known about the relationship between depression and CVD in Middle Eastern populations. The information will raise awareness among health care professionals and policy makers regarding the clinical significance of depression in Arab CV patients. It might contribute to development of culturally appropriate and effective mental health care services. Multiple databases were searched and 60 articles were assessed, including studies that investigated depression in Arab CV patient populations, physiological mechanisms of depression-CVD comorbidity, and intervention strategies that affect CV risk in depressed Arab patients. We discuss the extent to which this issue has been explored in Arab populations living in Middle East regions and Arab populations living abroad. We recommend that more comprehensive and in-depth research studies be conducted with Arab cardiac patients to enable implementation of culturally appropriate and effective mental health care interventions.

Impact of left ventricular function on health-related quality of life in coronary artery disease patients

OBJECTIVE

The aim of the study was to investigate the relation between health-related quality of life (HRQoL) and left ventricular systolic and diastolic function parameters in stable coronary artery disease (CAD) patients with mild and moderate heart failure.

MATERIALS AND METHODS

This study included 758 CAD patients. Left ventricular ejection fraction (LVEF) and ratio of peak velocities of early (E) and late (A) diastolic mitral inflow, ratio E/A, deceleration time, isovolumic relaxation time were assessed. Patients completed the SF-36 questionnaire.

RESULTS

There were no strong and significant associations between echocardiographic measures and HRQoL in NYHA I-II class patients. In NYHA III class in univariate linear regression analyses significant associations were found between LVEF and physical functioning (β=0.230, P=0.009) and role limitations due to physical problems (β=0.230, P=0.009) and these associations remain significant after adjustment for age, gender, hypertension, angina pectoris class, nitrate, ACE inhibitors and diuretics use. E/A ratio was significantly associated only with mental health domain (β=0.188, P=0.048), and this association remains significant after all adjustments.

CONCLUSIONS

In stable CAD patients with NYHA I-II functional class HRQoL was not strongly associated with left ventricular function; in NYHA III functional class patients' greater systolic function mainly was associated with better physical health and better diastolic function, with better mental health.

Depression and disease severity in patients with premature acute coronary syndrome

OBJECTIVES

The association between depression and cardiovascular disease severity in younger patients has not been assessed, and sex differences are unknown. We assessed whether major depression and depressive symptoms were associated with worse cardiovascular disease severity in patients with premature acute coronary syndrome, and we assessed sex differences in these relationships.

METHODS

We enrolled 1023 patients (aged ≤ 55 years) hospitalized with acute coronary syndrome from 26 centers in Canada, the United States, and Switzerland, through the GENdEr and Sex determInantS of cardiovascular disease: From bench to beyond-Premature Acute Coronary Syndrome study. Left ventricular ejection fraction, Killip class, cardiac troponin I, and Global Registry of Acute Coronary Events score data were collected through chart review.

RESULTS

The sample comprised 248 patients with major depression and 302 women. In univariate analyses, major depression was associated with a lower likelihood of having an abnormal left ventricular ejection fraction (odds ratio, 0.70; 95% confidence interval, 0.51-0.97; P = .03) and lower troponin I levels (estimate, -4.04; 95% confidence interval, -8.01 to -0.06; P = .05). After adjustment for sociodemographic and clinical characteristics, neither major depression nor depressive symptoms were associated with disease severity indices, and there were no sex differences.

CONCLUSION

The increased risk of adverse events in depressed patients with premature acute coronary syndrome is not explained by disease severity.
