Paraoxonase and arylesterase activities in dipper and non-dipper prehypertensive subjects.

Paraoxonase-1, a high-density lipoprotein linked enzyme complex, was shown to be decreased in several cardiovascular diseases. We aimed to explore whether serum paraoxonase and arylesterase activities differ in dipper and non-dipper prehypertensive subjects compared to healthy controls.Sixty prehypertensive subjects and 30 controls were enrolled.

Association between neutrophil to lymphocyte ratio and pulmonary arterial hypertension.

Objectives: Pulmonary hypertension (PH) is composed of a heterogeneous group of disorders marked by increased pulmonary artery resistance leading to right heart failure, with high mortality. Evidence is increasing to propose that inflammation plays a significant role in the pathophysiological mechanism. Increased prevalence of PH in patients with systemic inflammatory diseases is already known.

The association between mean platelet volume and coronary collateral circulation.

Background: Platelets are important in the pathogenesis of atherosclerotic complications. Higher mean platelet volume (MPV) levels are related to greater in vitro aggregation, and have been identified as an independent risk factor for myocardial infarction, and for death or recurrent vascular events.

Aim: To determine the relationship between MPV and the coronary collateral circulation.

Asymptomatic and isolated accessory mitral valve tissue in adult population: three case reports and review of the literature.

Accessory mitral valve tissue is a rare congenital cardiac anomaly and commonly it may cause left ventricular outflow tract obstruction (LVOTO). This anomaly occurs as a part of other congenital cardiac anomalies. However, it may be seen isolated.
