BACKGROUND Exercise capacity is known to be an important prognostic factor in patients with cardiovascular disease, but it is uncertain whether it predicts mortality equally well among healthy persons. There is also uncertainty regarding the predictive power of exercise capacity relative to other clinical and exercise-test variables. METHODS We studied a(More)
BACKGROUND The optimal pharmacologic means to restore and maintain sinus rhythm in patients with atrial fibrillation remains controversial. METHODS In this double-blind, placebo-controlled trial, we randomly assigned 665 patients who were receiving anticoagulants and had persistent atrial fibrillation to receive amiodarone (267 patients), sotalol (261(More)
Myopericarditis has been a rare or unrecognized event after smallpox vaccinations with the New York City Board of Health strain of vaccinia virus (Dryvax; Wyeth Laboratories, Marietta, Pennsylvania). In this article, the authors report an attributable incidence of at least 140 clinical cases of myopericarditis per million primary smallpox vaccinations with(More)
Smallpox is a devastating viral illness that was eradicated after an aggressive, widespread vaccination campaign. Routine U.S. childhood vaccinations ended in 1972, and routine military vaccinations ended in 1990. Recently, the threat of bioterrorist use of smallpox has revived the need for vaccination. Over 450,000 U.S. military personnel received the(More)
Left ventricular-right atrial (LV-RA) communications are rare intracardiac defects, often congenital in nature and clinically apparent during childhood. Acquired LV-RA shunts are encountered occasionally in the adult population as a result of a defect in the upper portion of the membranous ventricular septum. We describe the clinical and echocardiographic(More)
Peripheral edema often poses a dilemma for the clinician because it is a nonspecific finding common to a host of diseases ranging from the benign to the potentially life threatening. A rational and systematic approach to the patient with edema allows for prompt and cost-effective diagnosis and treatment. This article reviews the pathophysiologic basis of(More)
Congestive heart failure is a chronic, debilitating illness, with increasing prevalence in the elderly. It is one of the most common causes for hospital admission, and associated treatment costs are estimated at $20.2 billion. Despite improved survival with medical therapy, beneficial effects on quality of life have not been consistently reported. In(More)
CONTEXT In the United States, the annual incidence of myocarditis is estimated at 1 to 10 per 100,000 population. As many as 1% to 5% of patients with acute viral infections involve the myocardium. Although many viruses have been reported to cause myopericarditis, it has been a rare or unrecognized event after vaccination with the currently used strain of(More)
