Type A Behavior and Social Support in Coronary Heart Patients

Description: There currently exists a large body of research associating the Type A behavior pattern with an increased risk of coronary heart disease. Further, studies in the area of social support and health suggest that an absence of supportive relationships may result in a decreased resistance to disease in general, both physical and psychological. The present study sought to integrate the Type A research and social support literature through a correlational investigation of the relationship between Type A behavior and perceived quality of social support in 46 male subjects undergoing out-patient treatment for symptomatic coronary disease. It was hypothesized that the Type A pattern would show a significant inverse relationship with perceived quality of social support.

The Role of Anger/Hostility on Physiological and Behavioral Risk Factors for Coronary Heart Disease

Description: The purpose of this study was to examine the role of anger/hostility on physiological and behavioral coronary heart disease risk factors. It was hypothesized that anger/hostility would contribute to the severity of CHD via consummatory behaviors such as smoking, poor diet, and excessive alcohol consumption. Some researchers suggest that negative consummatory behaviors play a direct causal role in CHD. The present study proposed that hostility predisposes an individual to these behaviors, and that these behaviors in turn, contribute to CHD. Further, it was proposed that some of the anger that exists in CHD patients may result from the individual being unable to participate in some of their previous consummatory behaviors after suffering a myocardial infarction. Also, it was hypothesized that the construct of anger/hostility would be differentially related to consummatory behaviors.

Depression and Heart Rate Variability in Patients with Coronary Artery Disease

Description: Depression is an independent risk factor for morbidity and mortality in patients with coronary artery disease (CAD). Altered autonomic nervous system (ANS) activity, a common feature of depression, is also a risk factor for cardiac events in patients with CAD. Heart rate variability (HRV) reflects ANS activity, and reduced HRV predicts morbidity in cardiac populations. The purpose of this study was to determine whether differences in HRV exist between depressed and nondepressed patients with CAD. Twenty-one depressed inpatients, with angiographically documented CAD were retrospectively matched to 21 nondepressed CAD patients by sex, age, and smoking status. Demographic, medical, psychological interview data, and 24-hour ECG recordings were obtained. Depressed subjects had significantly lower HRV, or trends toward lower HRV, than nondepressed subjects, even after controlling for severity of CAD. Subject groups did not differ on left ventricular ejection fraction, history of myocardial infarction, or any other relevant medical variable assessed. These results suggest that depression is associated with decreased HRV in patients with CAD, and may help to explain the increased rates of cardiac events observed in CAD patients with depression.

Anxiety-Management Training for the Reduction of Type A Coronary-Prone Behavior

Description: The present study investigated the effects of anxiety management training on the reduction of Type A coronary-prone behavior in a college student population and utilized behavioral measures as well as self-report indices of change. Evaluations pre- and post-treatment included self-report measures of Type A behavior, empirically validated performance measures of the achievement-striving and time-urgency components of coronary-prone behavior, and a learned helplessness manipulation that has been associated with this behavior pattern. Analysis of covariance indicated that the treatment group changed in the desired direction on all self-report indices, and on most of the performance measures and helplessness scores that were used as dependent variables. Discussion centered on the implications of these data to theoretical and practical conceptualizations of coping behavior and coronary disease and cautions were expressed concerning clinical significance, maintenance, and generalization of results.

Sleep Duration, Sleep Insufficiency, and Carotid Intima-Media Thickness

Description: Cardiovascular disease is the leading cause of death in the United States. Chronic short sleep duration is also a significant public health problem and has been linked to several markers and outcomes of cardiovascular disease. To date, inconsistency of assessments of sleep duration and insufficiency, use of covariates, and cardiovascular disease measurement across studies limits strong conclusions about the relationship between sleep duration, sleep insufficiency, and cardiovascular disease. The current study examined the association between sleep duration, sleep insufficiency, and a marker of preclinical coronary heart disease (i.e., carotid intima-media thickness) in a community sample using a cross-sectional design. Some evidence for a relationship between sleep duration and cIMT was found, with longer sleep duration predicting higher cIMT in some segments. Additionally, the interaction between sleep duration and sleep insufficiency was significant. However, neither of these effects were significant after adjusting for age and in some cases race/ethnicity, suggesting demographics may explain this association. Actigraphy and sleep diary duration assessments demonstrated significantly different correlations with cIMT in some segments, suggesting the nature of the assessment method may impact the strength or direction of the relationship between sleep duration and cIMT. Limitations and future directions are discussed.
