Endothelial function is not always well preserved in obese patients with mild OSA

CPAP Improves Endothelial Function in Patients With Minimally Symptomatic OSA

Original Research T prevalence of minimally symptomatic OSA presenting without overt daytime sleepiness among middle-aged adults has been shown to be as high as 30%, 1 making OSA one of the most frequent disorders and, thus, of epidemiologic interest. Prospective epidemiologic studies have implicated OSA syndrome (OSAS) as an independent risk factor for stroke and myocardial ischemia. 2 Multipl...

Contrast nephropathy in patients with well-preserved renal function

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...

Preserved function of late-outgrowth endothelial cells in medically treated hypertensive patients under well-controlled conditions.

Endothelial progenitor cells (EPCs) participate in renal repair, but their number and function may be impaired by exposure to cardiovascular risk factors. The number of circulating EPCs is decreased in essential and renovascular hypertensive patients, but the effects of hypertension on EPC function are incompletely understood. We hypothesized that EPC function was preserved under well-controlle...
