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)
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 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 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)
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)
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)
OBJECTIVE To determine whether the 'dose' of treatment exposure, delivery of specific components of cognitive behavior therapy (CBT), patient adherence and/or use of antidepressants predict favorable depression and social support outcomes after 6 months of cognitive behavioral treatment. METHODS Secondary analyses of the intervention arm of the Enhancing(More)
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)
OBJECTIVE To compare the impact of network support and different types of perceived functional support on all-cause mortality or nonfatal reinfarction for patients with a recent acute myocardial infarction (AMI). DESIGN Participants were recruited from the Enhancing Recovery in Coronary Heart Disease (ENRICHD) trial; 2,481 AMI patients with depression or(More)
