BACKGROUND Disturbances in fibrinolytic activity, such as increase in plasminogen activator inhibitor (PAI) activity, have been linked with an increased risk for coronary artery disease (CAD) and myocardial infarction (MI). Since 4G4G homozygotes of an insertion/deletion (4G/5G) gene variation in the promoter of PAI-I have been shown to have increased(More)
BACKGROUND Presence of the D allele or homozygosity for the deletion (D) allele of the ACE insertion/deletion (I/D) polymorphism has been discussed as potent risk factor for coronary artery disease (CAD) and myocardial infarction (MI). METHODS AND RESULTS In 2267 male Caucasians the relation of the ACE I/D gene polymorphism to CAD and MI were(More)
BACKGROUND An insertion/deletion (I/D) polymorphism of the angiotensin I-converting enzyme (ACE) gene has been postulated to be associated with an increased risk of coronary artery disease (CAD) and myocardial infarction (MI). METHODS AND RESULTS In the present study, the effects of I/D gene polymorphism and of ACE activity on CAD and MI were investigated(More)
OBJECTIVE In arteriosclerosis and bypass graft stenosis, intimal proliferation is controlled by local and systemic growth factors, such as platelet derived growth factor (PDGF) or insulin. Intimal hyperplasia can be produced in organ culture models. Our aim was to compare neointima formation in two organ culture models of internal mammary artery (IMA) and(More)
A 38 year old male patient presented with a cardiac tumor. Echocardiography and visualization of the left atrium revealed a large myxoma. Surgical resection of the tumor was performed with the aid of cardiopulmonary bypass. The extensive size of the tumor base and its localisation at the posterior left atrial wall made a conventional approach impossible.(More)
In a prospective randomized study with 80 male patients scheduled for aorto-coronary bypass grafting we investigated the influence of pulsatile and nonpulsatile perfusion mode on cell count (leukocytes, platelets, hematocrit), concentrations of thromboxane (TXB2), 6-keto-prostaglandin F1 alpha (6-keto-PGF1 alpha), plasma hemoglobin, PMN-elastase, complement(More)
BACKGROUND The relations of the angiotensinogen (AGT) T174M and M235T gene polymorphisms to the risk of coronary heart disease (CHD) have been investigated in only a few studies with conflicting results. RESULTS Therefore, we analysed the relationship of the AGT gene polymorphisms to the presence and extent of CHD in 2250 male Caucasians whose coronary(More)
BACKGROUND There are conflicting results on the relationship of N5,N10-methylenetetrahydrofolate reductase C677T gene variation in coronary artery disease and myocardial infarction. METHODS AND RESULTS We analysed this gene variation in 2453 male Caucasians whose coronary anatomy was defined by coronary angiography. In the total sample, the C677T gene(More)
BACKGROUND The platelet membrane glycoprotein IIb/IIIa functions as a receptor for fibrinogen and von Willebrand factor during platelet aggregation. In a small case-control study, evidence has been presented that the PlA2 allele of the platelet glycoprotein GPIIIa PlA/A2 gene polymorphism might be an independent risk factor for acute myocardial infarction(More)
