Abnormal exercise hemodynamics in cardiac allograft recipients 1 year after cardiac transplantation. Relation to preload reserve.
The well-established elevation in left ventricular filling pressures during exercise in patients after transplantation may contribute to decreased exercise tolerance. A proposed mechanism for this increase in filling pressures is an abnormal pressure-volume homeostasis of the transplanted heart. Twenty-three patients undergoing routine 1-year evaluations performed supine bicycle exercise during...
متن کاملVascular complications after liver transplantation: a 5-year experience.
During the past 5 years, 104 angiographic studies were performed in 87 patients (45 children and 42 adults) with 92 transplanted livers for evaluation of possible vascular complications. Seventy percent of the studies were abnormal. Hepatic artery thrombosis was the most common complication (seen in 42% of children studied, compared with only 12% of adults) and was a major complication that fre...
متن کاملMetalloproteinases, Mechanical Factors and Vascular Remodeling
Chronic increases in arterial blood flow elicit an adaptive response of the arterial wall, leading to vessel enlargement and reduction in wall shear stress to physiological baseline value. Release of nitric oxide from endothelial cells exposed to excessive shear is a fundamental step in the remodeling process, and potentially triggers a cascade of events, including growth factor induction and m...
متن کاملThe effects of pre- and post-transplant anemia on 1-year survival after cardiac transplantation.
BACKGROUND Anemia is associated with a poor prognosis in heart failure. Recent studies have also suggested that anemia may be a predictor of survival after heart transplantation. METHODS We investigated whether anemia before or after orthotopic cardiac transplantation affected post-transplant survival and analyzed data from a historical cohort of 267 consecutive adult patients who underwent t...
متن کاملMediastinitis after cardiac transplantation.
OBJECTIVE Assessment of incidence and behavior of mediastinitis after cardiac transplantation. METHODS From 1985 to 1999, 214 cardiac transplantations were performed, 12 (5.6%) of the transplanted patients developed confirmed mediastinitis. Patient's ages ranged from 42 to 66 years (mean of 52.3 +/- 10.0 years) and 10 (83.3%) patients were males. Seven (58.3%) patients showed sternal stabilit...
