This study demonstrates the importance of analyzing survival by cause of death in order to achieve a better understanding of the prognostic indicators involved. It further emphasizes the need for analysis of risk factors in both univariate and multivariate models, and the danger of making judgements based on premature analysis of data on follow-up after(More)
BACKGROUND Endothelial cells release endothelium-derived relaxing factor (EDRF) in a variety of vascular beds, including the pulmonary circulation. However, the role of EDRF-mediated pulmonary-artery relaxation in chronic hypoxic lung disease is unknown. METHODS We studied endothelium-dependent relaxation mediated by EDRF in vitro in pulmonary arteries(More)
OBJECTIVES Measurement of changes in patients' perceptions of how differing states of health affect their lives and determination of the ability of preoperative variables to predict outcome after coronary artery bypass grafting. DESIGN Prospective study with completion of questionnaires before coronary artery bypass grafting and at three months, one year,(More)
We report three patients with cystic fibrosis and one patient with primary biliary cirrhosis and plexogenic pulmonary hypertension who have undergone heart-lung-liver transplantation as a combined procedure. Liver transplantation was necessary in the three patients with cystic fibrosis because of portal hypertension secondary to either hepatic fibrosis or(More)
Transbronchial biopsies (TBBs) are useful to diagnose acute rejection and infection in patients with lung transplants. The value of routine surveillance biopsies (S-TBBs) is not known, and such biopsies with a clinical indication are not without risk and are expensive. One hundred twenty-six 6-mo survivors of heart-lung transplantation (HLT) were studied to(More)
BACKGROUND A retrospective serologic study was made of 67 heart-lung and 295 heart transplant recipients (with transplantations at Papworth Hospital, Cambridge, England) to determine the incidence and clinical impact of Epstein-Barr virus infection. METHODS Epstein-Barr virus capsid antigen immunofluorescence tests were performed, and the antibody avidity(More)
Neural cell adhesion molecule (N-CAM) has been implicated in cellular interactions involved in cardiac morphogenesis and innervation. Immunohistochemical techniques and Western blot analysis were used to determine the localization and isoforms of N-CAM in the developing and extrinsically denervated human heart. Myocardial and conducting cells in the fetal(More)
We report our experience of herpes simplex virus infection in a series of 51 recipients of heart lung transplantation (HLT). Nine patients, all of whom were seropositive for the virus preoperatively, developed HSV infection. Seven episodes of culture-proved mucocutaneous HSV infection without evidence of pulmonary involvement occurred in four patients. Six(More)
The inotropic effects of impromidine have been studied and compared with those of histamine on human isolated left ventricular preparations stimulated at 1 Hz. Both drugs caused concentration-related increases in force of contraction and were of similar potency, although the maximum response to impromidine was markedly and significantly less than that to(More)
