Objectives: To investigate the effect of enalapril, losartan, and surgical coronary revascularisation on endothelial function, and the role of the angiotensin converting enzyme (ACE) insertion (I)/deletion (D) polymorphism. Design: Randomised, controlled, blinded end point study. Setting: University tertiary referral cardiac centre. Patients and interventions: 49 men awaiting coronary artery by...

C oronary artery bypass grafting (CABG) has long been the definitive, but nevertheless aggressive therapeutic approach for the treatment of patients with multi-vessel coronary artery disease. On the other hand, continuous improvement of devices and percutaneous techniques in interventional cardiology has led from the limited treatment of single, simple lesions to the extensive management of mul...

Atherosclerotic renovascular disease (ARVD) is associated with a high rate of cardiovascular disease and mortality. ARVD is an independent risk factor for adverse outcome in coronary artery disease and there is a correlation between the presence of ARVD and severity of cardiovascular disease. ARVD is the most common cause of secondary hypertension and can be found in up to half of elderly patie...

An unusual origin of the common interosseous artery is reported in the paper. During educational dissection of a 37-year-old male, a rare variation in the origin of common interosseous artery of the right upper limb was observed. The common interosseous artery directly separated from radial artery. The right anterior interosseous artery is continued from common interosseous artery. Anterior and...

OBJECTIVE The aim of this study was to analyse the arterial wall mechanics and the vasoreactive properties of the radial artery in comparison with those of the internal mammary artery and to discuss their implications for coronary bypass grafts. METHODS Measurements of pressure and diameter were obtained from cylindrical segments, whereas measurements of reactivity were obtained from ring seg...

BACKGROUND The radial artery has been increasingly used in CABG. However, angiographic outcome data have been limited. METHODS AND RESULTS We reviewed all coronary angiography procedures from February 1996 to October 2001 and selected patients with a radial artery bypass graft. Angiographic outcomes were divided into groups as (1) occluded, (2) severe disease (> or =70% stenosis, or string si...

Normally the brachial artery divides at the neck of the radius 2 to 3 cms below the crease of the elbow into two terminal branches namely ulnar and radial arteries .Common interrosseous artery arises from ulnar artery. In the present study there was difference in the terminations of brachial arteries in two limbs of the same body. In the left upper limb, the artery terminated into ulnar and rad...

Radial artery variations are of importance for clinicians, whether in angiographic examinations or surgical approaches. The high origin radial artery is the most frequent arterial variation observed in the upper limb, showing an incidence of 14.27% in dissection material and 9.75% in angiographic examination. In the present study an unusual course of the radial artery and its relation with the ...
