Hypertrophic cardiomyopathy (HCM) is characterized by disorganized myocardial architecture, and may cause ventricular arrhythmias and sudden death. The angiotensin-converting enzyme (ACE) with two deletion alleles (DD genotype) has been proposed to be associated with increased myocardial collagen content. We evaluated QT dispersion (QTd), which reflects regional differences in ventricular repolarization, ...

Several methods are used to induce latent left ventricular outflow tract (LVOT) gradients in patients with hypertrophic cardiomyopathy (HCM). We compared LVOT gradients induced by Valsalva manoeuvre (VM) and exercise echocardiography (EE) in patients with HCM treated with percutaneous transluminal septal myocardial ablation (PTSMA). Left ventricular outflow tract gradients were ...

Dilated cardiomyopathy (DC) has been reported in severe epidermolysis bullosa (EB) subtypes. Poor nutritional status, low carnitine levels, selenium deficiency, chronic iron overload, drugs and viral etiology have been proposed as potential contributors. This was a retrospective, descriptive, multicenter study describing EB patients that developed DC, and determining potential pre-disposing ...

Cibenzoline, a Class I antiarrhythmic agent, can attenuate the left ventricular pressure gradient (LVPG) in patients with hypertrophic obstructive cardiomyopathy (HOCM). An association between the insertion/deletion polymorphism of the angiotensin-converting enzyme (ACE) gene and the progression of left ventricular hypertrophy in patients with hypertrophic cardiomyopathy has been reported. The aim ...

BACKGROUND: Brugada syndrome can be overlooked due to its dynamic change in its electrocardiogram (ECG) manifestation. We hypothesized that positive ventricular late potential (VLP) in patients with nonspecific ECG would predict the inducible coved ST elevation (type-1 Brugada ECG) and the patients at high risk. METHODS: Thirty-four patients of nonspecific ...
