Psychological stress elicits measurable changes in sympathetic-parasympathetic balance and the tone of the hypothalamic-pituitary-adrenal axis, which might negatively affect the cardiovascular system both acutely-by precipitating myocardial infarction, left-ventricular dysfunction, or dysrhythmia; and chronically-by accelerating the atherosclerotic process.(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 Prediction of prognosis remains a major unmet need in new-onset heart failure (HF). Although several clinical tests are in use, none accurately distinguish between patients with poor versus excellent survival. We hypothesized that a transcriptomic signature, generated from a single endomyocardial biopsy, could serve as a novel prognostic(More)
BACKGROUND 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(More)
BACKGROUND After stroke, 10% of patients have adverse cardiac outcomes. Left insular damage may contribute to this by impairing sympathovagal balance (associated with cardiac structural damage and arrhythmias). METHODS The authors conducted a prospective study of 32 patients with left insular stroke (Group 1) and 84 patients with non-insular stroke/TIA(More)
