REGIONAL CHARACTERISTICS OF CARDIOMYOPATHY

Region-specific characteristics of hypertrophic cardiomyopathy (HC) and dilated cardiomyopathy (DC) were compared for 108 relevant patients living in Dubai (United Arab Emirates) and Moscow (Russia). Out of 49 sitizens of Dubai 17 had HC, 32 DC, and 59 Moscow patients had HC in 23, DC in 36 cases. It was found that HC in Dubai tends to run a silent latent course, involving mainly basal septum and right ventricle. Apical lesions were more typical for Moscow citizens who also display more severe myocardial impairment. DC in Dubai produces weaker cardiac insufficiency and arrhythmia. Incidence of idiopathic and periportal DC proved higher in Dubai, while alcohol and virus infection underlie DC more frequently in Moscow.
