Background— Although clopidogrel reduces the risk of cardiovascular episodes after coronary
events and stenting, a substantial number of incidents continue to occur. Methods and …

Background— This study aimed to determine whether QRS morphology identifies patients
who benefit from cardiac resynchronization therapy with a defibrillator (CRT-D) and whether it …

The hereditary Long QT syndrome (LQTS) is a genetic channelopathy with variable penetrance
that is associated with increased propensity for polymorphic ventricular tachyarrhythmias …

Background— An important determinant of successful cardiac resynchronization therapy for
heart failure is the position of the left ventricular (LV) pacing lead. The aim of this study was …

Abnormally long and short QT intervals have been shown to be associated with an increased
risk for life-threatening ventricular arrhythmias and sudden cardiac death. In recent years, …

Objectives : The study was designed to develop a simple risk stratification score for primary
therapy with an implantable cardioverter-defibrillator (ICD). Background : Current guidelines …

WITH THE INCREASING USE OF CONTRAST MEDIA in diagnostic and interventional
procedures, nephropathy induced by contrast media has become the third leading cause of …

Background— Type-1 long-QT syndrome (LQTS) is caused by loss-of-function mutations in
the KCNQ1-encoded I Ks cardiac potassium channel. We evaluated the effect of location, …

Objectives : The aims of this study were: 1) to evaluate risk factors influencing the clinical
course of mutation-confirmed adult patients with long QT syndrome (LQTS), 2) to study life-…

Background The Multicenter Automatic Defibrillator Implantation Trial with Cardiac
Resynchronization Therapy (MADIT-CRT) showed that early intervention with cardiac-…
