The number of cardiac beta-adrenoceptors and the positive inotropic effect of isoprenaline and milrinone were measured in cardiac membranes and isolated, electrically driven muscle strips from nonfailing donor hearts and from patients with mitral valve disease (NYHA II-III), ischemic heart disease, and dilated cardiomyopathy (NYHA IV). In nonfailing hearts,(More)
BACKGROUND In severe human heart failure, an increase in frequency of stimulation is accompanied by a reduced force of contraction in vivo and in vitro. The present study was aimed to investigate whether inotropic stimulation influences the inverse force-frequency relationship in failing human myocardium. METHODS AND RESULTS The effects of the(More)
OBJECTIVES Health-related quality of life and patient satisfaction have become important end points in cardiac surgery. Post-traumatic stress disorder has been described in patients with life-threatening heart disease. In this study, we investigated the occurrence of post-traumatic stress disorder in a sample of patients after cardiac surgery and compared(More)
To obtain region- and disease-specific transcription profiles of human myocardial tissue, we explored mRNA expression from all four chambers of eight explanted failing [idiopathic dilated cardiomyopathy (DCM), n=5; ischemic cardiomyopathy (ICM), n=3], and five non-failing hearts using high-density oligonucleotide arrays (Affymetrix U95Av2). We performed(More)
BACKGROUND To compare the efficacy and safety of tacrolimus and cyclosporine in heart transplantation, this single-center, prospective, randomized, open-label clinical trial was undertaken. METHODS Seventy-three adult patients were randomly assigned at the time of transplantation to receive either tacrolimus (n=43) or cyclosporine (n=30) as the primary(More)
BACKGROUND A combined treatment of statins and extracorporeal H.E.L.P.-apheresis (Heparin-mediated Extracorporeal LDL/fibrinogen Precipitation) has already been shown to be beneficial for coronary artery disease (CAD). Presumably high levels of LDL cholesterol, Lp(a), and fibrinogen also increase the risk for graft vessel disease (GVD). Therefore, we(More)
Hypercoagulability is a key contributor to acute cardiovascular syndromes and to various microcirculatory disorders. The use of heparin-mediated extracorporeal low-density lipoprotein/fibrinogen precipitation (HELP) apheresis makes a controlled, immediately effective reduction of clotting factors possible, and induces subsequent positive effects on plasma(More)
In this study, photochemotherapy (PCT) was used for adjunct immunosuppression in the first six months after heart transplantation (HTx). Fifteen patients after orthotopic HTx were included in the study; all received standard triple-drug immunosuppression including cyclosporine, azathioprine and glucocorticoids, but no adjunct therapy with mono- or(More)
Acute renal failure is a serious problem following heart transplantation. In first uncontrolled clinical trials, Urodilatin revealed beneficial effects in the prophylaxis and therapy of acute renal failure following heart and liver transplantation. Here, we present the first randomized, placebo-controlled, double-blind study on 24 patients following heart(More)
BACKGROUND The use of homografts in aortic valve replacement is an alternative to other prostheses and has been established in our department for 15 years. METHODS Since 1992, 360 homografts (HG) have been implanted in adult patients (mean age 51.6 years, 72.8% male). Prospective follow-up was done on an annual basis. RESULTS Thirty-day mortality was(More)
