BACKGROUND Clinical depression is associated with an increased risk for mortality in patients with a recent myocardial infarction (MI). Reduced heart rate variability (HRV) has been suggested as a possible explanation for this association. The purpose of this study was to determine if depression is associated with reduced HRV in patients with a recent MI.(More)
OBJECTIVE To assess whether patients receiving aerobic exercise training performed either at home or in a supervised group setting achieve reductions in depression comparable to standard antidepressant medication (sertraline) and greater reductions in depression compared to placebo controls. METHODS Between October 2000 and November 2005, we performed a(More)
OBJECTIVE Although depression and anxiety predict risk of cardiac mortality, the contributions of depression and anxiety to vagal cardiac control have not been systematically evaluated. The goal of this study was to examine the relationship between state anxiety and vagal control of heart rate in older adults with major depressive disorder (MDD). Older(More)
OBJECTIVES The purpose of this study was to assess whether depressive symptomatology was associated with vascular endothelial dysfunction in patients with coronary heart disease (CHD). BACKGROUND In patients with CHD, the presence of depression is associated with a two to four times increased risk of mortality, but the disease pathways involved are(More)
OBJECTIVE Prospective studies have demonstrated that anxiety predicts sudden cardiac death, but the mechanism underlying this increased risk is unclear. This study examined whether anxiety is associated with reductions in vagal control of heart rate in healthy volunteers. METHOD Trait anxiety (T-ANX) was measured, using the Spielberger State-Trait Anxiety(More)
BACKGROUND Although the DASH (Dietary Approaches to Stop Hypertension) diet has been shown to lower blood pressure (BP) in short-term feeding studies, it has not been shown to lower BP among free-living individuals, nor has it been shown to alter cardiovascular biomarkers of risk. OBJECTIVE To compare the DASH diet alone or combined with a weight(More)
BACKGROUND Patients with high blood pressure (BP) often exhibit syndrome X, an aggregation of abnormalities in carbohydrate and lipoprotein metabolism associated with increased risk of coronary heart disease (CHD). The present study evaluated the effects of a 6-month intervention involving either aerobic exercise training alone (EX only) or exercise(More)
BACKGROUND Depression is common in patients with acute myocardial infarction (AMI) and is associated with adverse health outcomes. However, the extent to which clinical depression is related to comorbid medical conditions is unknown. This study examined the degree of association between clinical depression and medical comorbidity in patients hospitalized(More)
OBJECTIVES The aim of this study was to assess the efficacy of exercise and antidepressant medication in reducing depressive symptoms and improving cardiovascular biomarkers in depressed patients with coronary heart disease. BACKGROUND Although there is good evidence that clinical depression is associated with poor prognosis, optimal therapeutic(More)
Depression has been shown to be a risk factor for mortality during the 12 months following an acute myocardial infarction (MI), but few studies have examined whether it is associated with increased risk over longer periods. Most of the existing studies utilized depression questionnaires rather than diagnostic interviews, the gold standard for clinical(More)
