BACKGROUND Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disorder involving diseased cardiac muscle. Bridging integrator 1 (BIN1) is a membrane-associated protein important to cardiomyocyte homeostasis and is downregulated in cardiomyopathy. We hypothesized that BIN1 could be released into the circulation and that blood-available BIN1 can(More)
OBJECTIVE Leptin is an adipocyte hormone important in appetite, energy homeostasis, neuroendocrine and haematopoietic function. Patients with renal failure often have elevated total and free leptin levels. Biologically active leptin fragments (leptin(22-56) and leptin(57-92)) have been identified, but whether these fragments are affected by renal failure(More)
BACKGROUND The Registry to Evaluate Early and Long-Term Pulmonary Arterial (PAH) Hypertension Disease Management (REVEAL) model was designed to predict 1-year survival in patients with PAH. Multivariate prediction models need to be evaluated in cohorts distinct from the derivation set to determine external validity. In addition, limited data exist on the(More)
Gastrointestinal bleeding (GIB) remains a significant problem after continuous-flow left ventricular assist device (CF-LVAD) implantation. We hypothesized that the subsequent need for blood transfusions in patients with GIB may reduce rates of cardiac transplantation. We performed a retrospective review of 232 patients implanted with the HeartMate II (HM(More)
BACKGROUND The majority of patients with pulmonary hypertension (PH) have non-pulmonary arterial hypertension PH (non-PAH PH) or multifactorial PH. The REVEAL score was designed to predict 1-year survival in patients with pulmonary arterial hypertension (PAH) only. It is unknown whether this model is applicable to a more general population of PH patients.(More)
