Circulating KCNH2 Current-Activating Factor in Patients with Heart Failure and Ventricular Tachyarrhythmia

BACKGROUND It is estimated that approximately half of the deaths in patients with HF are sudden and that the most likely causes of sudden death are lethal ventricular tachyarrhythmias such as ventricular tachycardia (VT) or fibrillation (VF). However, the precise mechanism of ventricular tachyarrhythmias remains unknown. The KCNH2 channel conducting the delayed rectifier K(+) current (I(Kr)) is...

Lorcainide in patients with refractory ventricular tachyarrhythmia.

Lorcainide, a new antiarrhythmic agent with local anesthetic or membrane-stabilizing properties similar to those of quinidine, was tested in 76 patients with diverse types of heart disease and recurrent ventricular tachycardia or ventricular fibrillation. Lorcainide was administered for 72 to 96 hours in a dose ranging from 200 to 400 mg daily. Evaluation of drug efficacy involved ambulatory mo...

Circulating Endothelial Cells in Patients with Heart Failure and Left Ventricular Dysfunction

INTRODUCTION AND AIMS Acute and chronic heart failure may manifest different degrees of endothelial damage and angiogenesis. Circulating endothelial cells (CEC) have been identified as marker of vascular damage. The aim of our study was to evaluate the evolution of the CEC at different stages of patients with heart failure. We also investigated a potential correlation between CEC and markers of...

Circulating microRNAs and Outcome in Patients with Acute Heart Failure.

BACKGROUND The biomarker value of circulating microRNAs (miRNAs) has been extensively addressed in patients with acute coronary syndrome. However, prognostic performances of miRNAs in patients with acute heart failure (AHF) has received less attention. METHODS A test cohort of 294 patients with acute dyspnea (236 AHF and 58 non-AHF) and 44 patients with stable chronic heart failure (CHF), and...
