background: serum n-terminal pro-brain natriuretic peptide (nt-probnp), a polypeptide secreted by ventricular myocytes in response to stretch, was suggested as a predictor of adverse prognosis of the acute coronary syndrome (acs). we examined the association between nt-probnp level and angiographic findings in acs patients to determine whether it could be used as a predictor of the severity of ...

A randomized trial of surgical vs nonsurgical management was carried out in men 60 years of age or younger who had recovered from a recurrent myocardial infarction. Of 205 patients considered, 100 had few or no symptoms and had coronary vessels favorable for bypass grafting; these patients fulfilled the trial conditions and were randomized (50 surgical and 50 nonsurgical). In 41 patients (elect...

A 58 year old woman was referred to our centre for aortic valve replacement because of a severe symptomatic aortic stenosis. She had no coronary risk factors. Rest ECG showed complete left bundle branch block. Coronary angiography showed normal coronary anatomy (fig 1). The gradient over the aortic valve could not be measured because of repetitive iatrogenic induction of ventricular tachycardia...

Background Dynamic gadolinium contrast-enhanced (DCE) vessel wall MRI has recently been used to compute a set of model-based contrast kinetic parameters (e.g. K and Vp) that can well characterize the extent of inflammation in carotid plaques [1,2]. However, no studies have shown its feasibility in coronary artery wall, presumably due to the technical challenges in imaging such a constantly-movi...

conclusions the authors describe the second reported case of eptifibatide-induced severe thrombocytopenia associated with cardiac surgery. in this case, discontinuation of eptifibatide and transfusion of apheresis platelets increased the platelet count (137 k/ul) the following day, and the patient subsequently underwent successful coronary artery surgery using cardiopulmonary bypass. introducti...

PURPOSE To quantitatively assess the performance and reproducibility of 3D spiral coronary artery wall imaging with beat-to-beat respiratory-motion-correction (B2B-RMC) compared to navigator gated 2D spiral and turbo-spin-echo (TSE) acquisitions. MATERIALS AND METHODS High-resolution (0.7 × 0.7 mm) cross-sectional right coronary wall acquisitions were performed in 10 subjects using four techn...

Tako-Tsubo cardiomyopathy (TTC) is an acute reversible cause of segmental myocardial dysfunction that is poorly understood and cannot be explained by the occlusion of a single coronary vessel. Its clinical presentation is similar to that of acute coronary syndrome and is often precipitated by a severe psychological or physical stress.

leaf anatomy of 27 species of potentilla l. (rosaceae), representing 9 sections and four related genera, especially tylosperma botsch., schistophyllidium (juz. ex fed.) ikonn., drymocallis fourr. ex rydb., and sibbaldia l. from iran were studied using light microscopy. the most outstanding characters of blade and midrib were measured. the result revealed a number of taxonomically important char...
