CONTEXT Depression and low perceived social support (LPSS) after myocardial infarction (MI) are associated with higher morbidity and mortality, but little is known about whether this excess risk can be reduced through treatment. OBJECTIVE To determine whether mortality and recurrent infarction are reduced by treatment of depression and LPSS with cognitive(More)
The interaction of Type A behavior and social support in relation to the degree of coronary artery disease (CAD) severity was investigated. One hundred thirteen patients undergoing diagnostic coronary angiography received the Type A structured interview (SI) and completed a battery of psychometric tests, including the Perceived Social Support Scale (PSSS).(More)
OBJECTIVE Depression has been related to poor medical prognosis in patients with coronary artery disease and to diminished quality of life after coronary artery bypass graft surgery (CABG). However, prior studies have not fully examined the impact of depression on medical outcomes after CABG. The purpose of this study was to determine the independent(More)
BACKGROUND Observational studies have suggested that psychological stress increases the incidence of sudden cardiac death. Whether emotional or physical stressors can trigger spontaneous ventricular arrhythmias in patients at risk has not been systematically evaluated. METHODS AND RESULTS Patients with implantable cardioverter-defibrillators (ICDs) were(More)
BACKGROUND Cognitive, behavioral, and interpersonal vulnerabilities have been studied in patients fulfilling diagnostic criteria for major depression and dysthymia. The extent to which these vulnerabilities are present in cardiac patients with mild to moderate depressive symptoms--a risk factor for mortality--is unknown. Moreover, few studies have examined(More)
Cardiac vagal control (CVC), an index of parasympathetic contribution to cardiac regulation, has been linked to enhanced executive functioning (EF). However, findings to date have been based on small or unique samples. Additionally, previous studies assessed the CVC-EF link only during rest or recovery period from a cognitive challenge, but not during both(More)
BACKGROUND Depressive symptoms are an established predictor of mortality and major adverse cardiac events (defined as nonfatal myocardial infarction or hospitalization for unstable angina or urgent/emergency revascularizations) in patients with acute coronary syndrome (ACS). This study was conducted to determine the acceptability and efficacy of enhanced(More)
OBJECTIVE The Enhancing Recovery in Coronary Heart Disease study was a multicenter clinical trial in which patients with depression and/or low perceived social support after an acute myocardial infarction were randomly assigned to an intervention consisting of cognitive behavior therapy and, in some cases, sertraline, or to usual care. There was no(More)
BACKGROUND Even mild depressive symptoms during hospitalization are an independent risk factor for mortality after acute coronary syndromes (ACS). The mortality risk is highest for patients whose depressive symptoms persist after ACS. Low adherence to medications that reduce the risk of subsequent cardiac events may be one of the mechanisms underlying the(More)
The central nervous system (CNS) effects of mental stress in patients with coronary artery disease (CAD) are unexplored. The present study used positron emission tomography (PET) to measure brain correlates of mental stress induced by an arithmetic serial subtraction task in CAD and healthy subjects. Mental stress resulted in hyperactivation in CAD patients(More)
