Metoprolol improves endothelial function in patients with cardiac syndrome X
Endothelial dysfunction which is manifested by the loss of nitric oxide bioavailability, is an increasingly recognized cause of cardiac syndrome X (CSX) and beta blockers are used for the treatment of this syndrome. Thus, the aim of this study was to investigate effects of metoprolol, as a beta blocker, on endothelial function in CSX patients. The study included 25 CSX patients (20 female/ 5 ma...

متن کاملSex differences in exercise induced left ventricular dysfunction in patients with syndrome X.
Clinical, electrocardiographic, and scintigraphic data were reviewed from 32 patients (18 men and 14 women) who had syndrome X (chest pain, evidence of ischaemia, and normal coronary arteries without coronary vasospasm). The mean (SD) resting left ventricular ejection fraction, determined by first pass radionuclide angiography was 62.6 (9.2)% and was greater than 50% in all subjects. There was ...
متن کاملtheophylline effects in patients with syndrome x
a role of adenosine in pathogenesis of syndrome x has recently been postulated. previous studies suggest that aminophylline (an adenosine receptor blocker) improves exercise tolerance in this disorder. present study was performed to examine the efficacy of theophylline in syndrome x and to determine the incidence of cardiovascular risk factors and clinical, ecg and angiographic findings in thes...
متن کاملSuccinylcholine-induced hyperkalemia in patients with renal failure?
T he administration of succinylcholine (SCh) in humans results in a mild and transient hyperkalemia. In normal individuals, the increase in serum potassium (K) is approximately 0.5–1.0 mEq/L, occurs within 3–5 minutes after the IV administration of SCh, and lasts ,10–15 minutes (1). This increase is probably caused by K release from cells as a result of depolarization at the neuromuscular junct...
