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 The incidence of sudden cardiac death increases in populations who experience disasters such as earthquakes. The physiological link between psychological stress and sudden death is unknown; one mechanism may be the direct effects of sympathetic arousal on arrhythmias. To determine whether mental stress alters the induction, rate, or termination(More)
OBJECTIVES Depression has been related to mortality in patients with CAD and to medical morbidity after CABG; however, prior studies have not examined the contribution of presurgical depressive symptoms to mortality after CABG. The purpose of this study was to determine the independent contribution of presurgical symptoms of depression to 2-year cardiac(More)
OBJECTIVES We tested whether improvements in depressive symptoms precede improved adherence to aspirin in patients with acute coronary syndromes (ACS). BACKGROUND Depression is associated with medication nonadherence in patients with ACS, but it is unclear whether changes in depression impact on adherence. METHODS Electronic medication monitoring was(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)
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)
CONTEXT Depression consistently predicts recurrent events and mortality in patients with acute coronary syndrome (ACS), but it has 2 core diagnostic criteria with distinct biological correlates-depressed mood and anhedonia (loss of pleasure or interest). OBJECTIVE To determine if depressed mood and/or anhedonia predict 1-year medical outcomes for patients(More)
