OBJECTIVES To prove whether intramyocardial transplantation of combined skeletal myoblasts (SM) and mononuclear bone marrow stem cells is superior to the isolated transplantation of these cell types after myocardial infarction in rats. METHODS In 67 male Fischer rats myocardial infarction was induced by direct ligature of the LAD. Seven days(More)
Despite the very important use of arterial bypass conduits, vein grafts remain one cornerstone in coronary surgery. Newer studies show a saphenous vein graft patency of about 60% at 10 years postoperatively. This article reviews the in vivo (animal) models of vein graft disease. According to the different models, the findings on pathology of graft(More)
OBJECTIVE C-type natriuretic peptide (CNP), which is produced by vascular endothelial cells, exhibits anti-proliferative and anti-inflammatory effects. Cytotoxic T-lymphocytes may be involved in vein graft disease. Attenuation of vein graft disease necessitates a remodelling of the arterialized vein towards a more contractile phenotype which is(More)
AIMS Despite the lower patency of venous compared with arterial coronary artery bypass grafts, approximately 50% of grafts used are saphenous vein conduits because of their easier accessibility. In a search for ways to increase venous graft patency, we applied the results of a previous pharmacological study screening for non-toxic compounds that inhibit(More)
BACKGROUND The N-terminal fragment of pro-brain type natriuretic peptide (NT-proBNP) is an established biomarker for cardiac failure. OBJECTIVE To determine the influence of preoperative serum NT-proBNP on postoperative outcome and mid-term survival in patients undergoing coronary artery bypass grafting (CABG). METHODS In 819 patients undergoing(More)
The effects of cold storage using Custodiol® (Histidine-Tryptophan-Ketoglutarate, HTK) or isotonic saline solution on mitochondrial function in hearts (left and rights ventricles) and various blood vessels of pigs were investigated. Hearts, saphenous veins, internal-mammary-arteries and aortas of male landrace pigs were harvested and exposed to cold(More)
PATIENTS AND METHODS 140 patients with aortic dissection type A were admitted for cardiac surgery. Seventy-seven patients experienced their dissection in the winter season (from November to April). We analyzed cases of ascending aortic dissection associated with alpine skiing. RESULTS In 17 patients we found skiing-related aortic dissections. Skiers were(More)
We present our initial experience with intraoperative angiographic evaluation of coronary artery bypass grafts placed on the beating heart. Thirty-three grafts were investigated in 23 patients. Transfemoral angiography was performed using an OEC 9800 mobile C-arm. Spasm of the graft and/or target vessel was present in 11 grafts, two grafts were severely(More)
OBJECTIVE To investigate whether common risk stratification models in cardiac surgery predict perioperative outcome of coronary artery bypass grafting (CABG) in patients with previous percutaneous coronary interventions (PCIs). METHODS We retrospectively analyzed the perioperative mortality and morbidity of 367 patients with prior elective PCI versus 2361(More)
