Vitamin D levels in white coat and sustained hypertension.

Objective: The plasma levels of vitamin D in patients with white coat hypertension (WCHT) have not been studied previously. The aim of this study was to evaluate vitamin D levels in WCHT and compare with sustained hypertension (SHT) and with normotension (NT).

Patients And Methods: Fifty-three normotensive, 42 WCHT, and 59 SHT patients were recruited in this study.

Relationship between red cell distribution width and contrast-induced nephropathy in patients who underwent primary percutaneous coronary intervention.

Objective: This study evaluated the relationship between contrast-induced nephropathy (CIN) and red cell distribution width (RDW) in patients who underwent primary percutaneous coronary intervention (PCI).

Methods: A total of 359 patients with ST elevation myocardial infarction (STEMI) who had undergone primary PCI were included in the study. An increase of 25% in serum creatinine value after 48 h, or an increase of >0.

Effect of CPAP on New Endothelial Dysfunction Marker, Endocan, in People With Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) is associated with increased cardiovascular (CV) morbidity and mortality. Endocan is a surrogate endothelial dysfunction marker that may be associated with CV risk factors. In this study, we tested whether serum endocan is a biomarker for OSA.

The serum copeptin levels in obstructive sleep apnea patients with prehypertensive.

Objective: Copeptin is a precursor of AVP, an antidiuretic hormone, plays a pivotal role in the maintenance of cardiovascular homeostasis. Obstructive sleep apnea syndrome (OSAS) is related to cardiovascular disease. We sought to evaluate the serum copeptin levels in newly diagnosed prehypertensive patients with OSAS.
