AIMS Vitamin D deficiency is a highly prevalent, global phenomenon. The prevalence in heart failure (HF) patients and its effect on outcome are less clear. We evaluated vitamin D levels and vitamin D supplementation in patients with HF and its effect on mortality. METHODS AND RESULTS 25-Hydroxyvitamin D [25(OH)D] levels were evaluated in HF patients from(More)
We investigated the diameter of epicardial coronary arteries in 12 patients (ten men) with dilated cardiomyopathy, and compared to 21 normal persons (14 men). Dilated cardiomyopathy patients were younger than controls with no difference in height, weight and body surface area. Ejection fraction was lower in dilated cardiomyopathy compared to normals(More)
Scytalidium dimidiatum, a dematiaceous fungus, has been well established as an agent of dermatomycosis. There are few reports of invasive infection caused by S. dimidiatum; most infections occurred in immunocompromised hosts. We present an immunocompetent patient with pleural S. dimidiatum infection and review nine other published cases of invasive S.(More)
BACKGROUND Careful donor and recipient selection are important factors for the success of heart transplantation. Currently, donors with a history of alcohol use are routinely accepted despite the potential deleterious effects of alcohol on the heart. METHODS We examined the frequency of chronic alcohol use (> 2 ounces of pure alcohol daily for > or = 3(More)
BACKGROUND Intravenous gammaglobulin (i.v.IG) contains anti-idiotypic antibodies that are potent inhibitors of HLA-specific alloantibodies in vitro and in vivo. In addition, highly HLA-allosensitized patients awaiting transplantation can have HLA alloantibody levels reduced dramatically by i.v.IG infusions, and subsequent transplantation can be accomplished(More)
BACKGROUND The coronary microvasculature may be abnormal even in the presence of angiographically normal epicardial arteries. Abnormalities of small coronary vessels have been invoked as a cause of angina. METHODS AND RESULTS To quantitatively evaluate the morphology of capillaries in patients with idiopathic dilated cardiomyopathy (DCM) or the syndrome(More)
Orthotopic heart transplantation (OHT) with bicaval and pulmonary venous anastomoses avoids the large atrial anastomoses of the standard biatrial technique. To determine whether the bicaval technique improves atrial performance, we used Doppler echocardiography to study 13 patients with bicaval OHT, 15 with biatrial OHT, and 8 normal subjects. All were in(More)
Renal function and urea are frequently abnormal in patients with heart failure (HF) and are predictive of increased mortality. The relative importance of each parameter is less clear. We prospectively compared the predictive value of renal function and serum urea on clinical outcome in patients with HF. Patients hospitalized with definite clinical diagnosis(More)
Acute myocarditis is one of the most challenging diseases to diagnose and treat in cardiology. The true incidence of the disease is unknown. Viral infection is the most common etiology. Modern techniques have improved the ability to diagnose specific viral pathogens in the myocardium. Currently, parvovirus B19 and adenoviruses are most frequently identified(More)
BACKGROUND Cytomegalovirus is a frequent cause of infection and morbidity after heart transplantation, especially in patients treated with antilymphocytic drugs where the incidence may be as high as 50%. METHODS To determine the efficacy of combined antiviral and intravenous immune globulin therapy for prevention of cytomegalovirus disease in transplant(More)
