Sequence Alterations of I(Ks) Potassium Channel Genes in Kazakhstani Patients with Atrial Fibrillation.

Introduction: Atrial fibrillation (AF) is the most common sustained arrhythmia, and it results in significant morbidity and mortality. However, the pathogenesis of AF remains unclear to date. Recently, more pieces of evidence indicated that AF is a multifactorial disease resulting from the interaction between environmental factors and genetics.

RYR2 sequencing reveals novel missense mutations in a Kazakh idiopathic ventricular tachycardia study cohort.

Channelopathies, caused by disturbed potassium or calcium ion management in cardiac myocytes are a major cause of heart failure and sudden cardiac death worldwide. The human ryanodine receptor 2 (RYR2) is one of the key players tightly regulating calcium efflux from the sarcoplasmic reticulum to the cytosol and found frequently mutated (<60%) in context of catecholaminergic polymorphic ventricular tachycardia (CPVT1). We tested 35 Kazakhstani patients with episodes of ventricular arrhythmia, two of those with classical CPVT characteristics and 33 patients with monomorphic idiopathic ventricular arrhythmia, for variants in the hot-spot regions of the RYR2 gene.

[Immune status of patients with cardiac arrhythmias: idiopathic and in primary heart disease].

Aim: A detailed description of immune status abnormalities of adult patients with heart arrhythmia either idiopathic or in combination with primary heart disease such as chronic myocarditis and dilated cardiomyopathy (DCMP).

Material And Methods: Eighty two consecutive patients aged 16-57 years admitted to the L.A.

[C-reactive protein level and rate of detection of autoantibodies to beta(1)-adrenoreceptors in patients with supraventricular tachyarrhythmias].

In order to assess concentration of C-reactive protein (CRP) and prevalence of autoantibodies against beta(1)-adrenoreceptors (abeta(1)-AR) in patients with cardiac supraventricular arrhythmias we studied 53 patients with arrhythmias and 20 healthy control subjects. Patients with idiopathic arrhythmias (atrial fibrillation or flutter and atrial tachycardia, n=35) comprised group I. Group II was formed of 15 patients with supraventricular arrhythmias and dilated cardiomyopathy (DCM) or chronic myocarditis.
