BACKGROUND: While patients with chronic kidney disease (CKD) have a high prevalence of classical coronary risk factors, there is increasing evidence that atherosclerosis is different in renal compared to nonrenal patients. Therefore, the present study compares changes in different vessels obtained at cardiac surgery between patients with early and advanced CKD and nonrenal control patients. METHODS AND RESULTS: Fifty patients undergoing cardiac bypass surgery were divided into three groups: (i) 24 control patients with creatinine <1...

OBJECTIVES: We tested the hypothesis of whether an inhibition of the nitroglycerin (GTN) bioactivating enzyme mitochondrial aldehyde dehydrogenase (ALDH-2) contributes to GTN tolerance in human blood vessels. BACKGROUND: The hemodynamic effects of GTN are rapidly blunted by the development of tolerance, a phenomenon associated with increased formation of reactive oxygen species (ROS). Recent studies suggest that ROS-induced inhibition of ALDH-2 accounts for tolerance in animal models...

1. The present study investigates the vasoselectivity of lercanidipine (LER), a 1,4-dihydropyridine calcium channel blocker, compared with amlodipine (AML) and nifedipine (NIF) in human cardiovascular tissue. Experiments were performed either in human left ventricular failing myocardium (orthotopic heart transplants) or in isolated right atrial trabeculae and isolated vessel preparations of arteria mammaria obtained from patients undergoing aortocoronary bypass operation. 2. The obtained rank order for the L-type Ca2+ channel affinity in human tissue was LER > NIF >or= AML...

INTRODUCTION: The use of arterial grafts in the myocardial revascularization procedures has grown more popular due to their long-term patency compared with that of the great saphenous vein. The aim of this retrospective study was to assess our experience and first results in the group of patients who had underwent revascularization procedures using their radial artery. MATERIAL AND METHODOLOGY: Between 7/2000-2/2004, 51 patients of acceptable age, aged 69.0 +/- 9...

The coronary subclavian-steal-syndrome is a rare cause for angina pectoris following A. mammaria interna bypass operation. A 72-year-old male patient presented with vertigo and angina pectoris. A three vessel coronary artery disease was known and coronary artery surgery with three aortocoronary bypasses had been performed a year prior to presentation. A difference in peripheral arterial pressure between the right (150/80 mmHg) and the left (125/75 mmHg) arm was noted at physical examination. Color Doppler sonography of the left vertebral arteria exhibited a retrograde flow suggesting a coronary subclavian-steal-syndrome...

BACKGROUND: In experimental animal models, long-term in vivo treatment with nitroglycerin (NTG) induces both endothelial dysfunction and tolerance to nitrates. However, it is still controversial whether nitrate tolerance in humans is associated with both endothelial dysfunction and impaired vascular response to nitrovasodilator-derived NO. METHODS AND RESULTS: Patients undergoing elective bypass surgery were randomized to receive 48 hours of continuous NTG infusion (NTG group) or no nitrate therapy (control group)...

Femoropopliteal bypass with below-the-knee anastomosis and the use of an autogenous saphenous vein yields the best results in longtime patency rate compared to the use of other graft materials. With anastomosis above the knee equally good results are also found with other graft materials. However, the late results show that even the saphenous vein is no perfect vessel substitute. Therefore, the indication for operation should be selected mainly for limb salvage and rest pain in stages III and IV, and the saphenous vein should be preserved for below-the-knee anastomosis...

Three agents with K(+)-channel-opening activity--nicorandil, bimakalim (EMD 52692), and EMD 56431--were tested for vasorelaxation abilities in human coronary artery and human arteria mammaria. The potency orders were bimakalim = EMD 56431 > nicorandil for relaxation in human coronary artery and bimakalim = EMD 56431 > nicorandil in human arteria mammaria. These data demonstrate that K(+)-channel openers are effective vasorelaxant agents in human coronary artery and human arteria mammaria. Bimakalim and EMD 56431 were more potent than nicorandil, a drug that also activates guanylate cyclase...

The frequency and the treatment of the sternal fractures is discussed by the authors. 5 patients with sternal fractures have been treated by the authors, and 3 of them were operated on. In one patient early operation has been performed, and in another the osteosynthesis of the sternum has been carried out 3 years after the lesion. In the 3d patient the bone piece broken down from the sternum damaged the arteria mammaria int. sin., necessitating thus surgical intervention.
