BACKGROUND Reversible left ventricular dysfunction precipitated by emotional stress has been reported, but the mechanism remains unknown. METHODS We evaluated 19 patients who presented with left ventricular dysfunction after sudden emotional stress. All patients underwent coronary angiography and serial echocardiography; five underwent endomyocardial(More)
In patients with chronic heart failure, depression is common and associated with poor quality of life, more frequent hospitalizations, and higher mortality. Spiritual well-being is an important, modifiable coping resource in patients with terminal cancer and is associated with less depression, but little is known about the role of spiritual well-being in(More)
BACKGROUND Little is known about symptoms and their burden in outpatients with chronic heart failure. Diverse symptoms may be associated with poor heart failure-related quality of life, and depression may be related to increased symptoms. METHODS AND RESULTS The number of symptoms and symptom distress (physical symptoms on the Memorial Symptom Assessment(More)
OBJECTIVES The aim of this study was to report a series of patients with stress cardiomyopathy precipitated by the intravenous administration of catecholamines and beta-receptor agonists. BACKGROUND Stress cardiomyopathy is a syndrome of transient cardiac dysfunction precipitated by intense emotional or physical stress. Excessive sympathetic stimulation(More)
OBJECTIVES This study tested the hypothesis that angiotensin-converting enzyme (ACE) inhibitors attenuate beta-adrenergic contractility in patients with idiopathic dilated cardiomyopathy (DCM) through nitric oxide (NO) myocardial signaling. BACKGROUND The ACE inhibitors increase bradykinin, an agonist of NO synthase (NOS). Nitric oxide inhibits(More)
BACKGROUND Lymphocytic myocarditis is a clinically important condition that is difficult to diagnose and distinguish. We hypothesized that the transcriptome obtained from an endomyocardial biopsy would yield clinically relevant and accurate molecular signatures. METHODS AND RESULTS Microarray analysis was performed on samples from patients with(More)
During the past few years, a novel syndrome of heart failure and transient left ventricular systolic dysfunction precipitated by acute emotional or physical stress has been described. While patients with “stress cardiomyopathy” (SCM) typically present with signs and symptoms that resemble an acute coronary syndrome, it has become clear that this syndrome(More)
BACKGROUND Whether myocardial recovery occurs more frequently in peripartum cardiomyopathy (PPCM) than in recent onset cardiomyopathies in men and nonperipartum women has not been prospectively evaluated. This was examined through an analysis of outcomes in the Intervention in Myocarditis and Acute Cardiomyopathy 2 (IMAC2) registry. METHODS AND RESULTS(More)
There is considerable epidemiological evidence supporting the association between chronic emotional stress and coronary heart disease (CHD). Emotional factors that have been linked to athero-sclerosis and adverse cardiac events include primarily negative affective disorders such as depression, anxiety, anger, and hostility. 1,2 It is now well established(More)
