BACKGROUND Genetic mutations are the most common cause of hypertrophic cardiomyopathy (HCM) and an increasingly recognized cause of dilated cardiomyopathy. Autosomal dominant HCM is caused by mutations in sarcomere proteins; such mutations are not universally present, however, and fail to account for &40% of cases of phenotypic HCM. To add further(More)
During the last few years DNA microarray studies of gene expression changes in human atrial tissues from patients with and without atrial fibrillation (AF) have been performed. For this purpose, tissue samples are usually collected from AF patients undergoing open heart surgery. These investigations have limitations associated with the unavoidable(More)
Gene expression level of 2900 genes was studied by cDNA microarray in patients with atrial fibril-lation (AF) or sinus rhythm. Gene transcripts were analysed in samples of right atrial appendages from 47 patients undergoing surgery for valve repair or coronary artery bypass. Standard correlation analysis and two dimensional hierarchical clustering were used(More)
Inherited long QT syndrome (LQTS) refers to the primary electrical diseases of the heart. It is characterized by QT prolongation on resting ECG and syncope due to life-threatening ventricular arrhythmias. This review focuses on diagnosis, differential diagnosis, risk stratification of sudden cardiac death, and treatment strategy of patients with most(More)
Results of an observational study. devoted to prevention of thromboembolic complications in patients with atrial fibrillation undergoing catheter pulmonary vein atrium isolation are discussed. Patients (n= 199) were divided into two comparable groups depending on the anticoagulant (rivaroxaban or warfarin) used. Clinical thromboembolic and/or hemorrhagic(More)
AIM to elucidate contribution of atrial fibrillation (AF) to mortality from various causes among men and women in Russia. MATERIAL AND METHODS We analyzed data from samples of population of Moscow and Petersburg (Leningrad) aged 35-74 years examined in different years. Total number of subjects was 20045 (15107 men), response rate was 75%. Examination was(More)
Four patients with long QT type 2, aged 11 to 18 years from unrelated families, with recurrent syncope and polymorhic ventricular tachycardia were studied. Long QT syndrome was diagnosed in these children at ages 4 to 7 years. Syncope, QT prolongation on electrocardiogram (corrected QT interval ≥ 490 milliseconds), notched T-wave morphology, bradycardia,(More)
