Association of potassium disorders with the mode of death and etiology in patients with chronic heart failure: the INCOR-HF study.

Observational studies suggest a U-shaped association between serum potassium (K⁺) levels and mortality in patients with chronic heart failure (CHF). However, the mode of death in patients with HF and K⁺ disorders remains speculative. To investigate the association between potassium disorders and the mode of death in patients with CHF.

Do statins decrease testosterone in men? Systematic review and meta-analysis.

Purpose: Statins are one of the most prescribed classes of drugs worldwide to treat hypercholesterolemia and dyslipidemia. By lowering the level of cholesterol, the use of statin could cause a reduction in testosterone levels. The objective was to evaluate whether the continued use of statins in patients with hypercholesterolemia causes a deficiency in testosterone and other sex hormones.

A Novel Percutaneous Technique for Left Ventricular Assist Device Deactivation Using a Left Atrial Appendage Occluder in the Outflow Cannula.

Reverse cardiac remodeling may occur in some left ventricular assist device (LVAD) recipients. Although considered the standard therapy, surgical device explantation with repeat sternotomy might be undesirable or very high risk. On the other hand, there are few data reporting minimally invasive percutaneous LVAD deactivation.

Early reduction of pulmonary arterial hypertension in patients using a long-term mechanical ventricular assistance device: a cross-sectional study.

Background: Severe pulmonary arterial hypertension (PAH) is a contraindication for heart transplantation (HT). It has been correlated with increased early and late mortality, mainly associated with right ventricular failure. Ventricular assistance devices (VADs) can promote reduction of intracardiac pressures and consequent reduction of PAH over the medium and long terms, thus enabling future candidature for HT.
