MYOCARDIAL REMODELLING TYPES IN HYPERTROPHIC NON-OBSTRUCTIVE CARDIOMYOPATHY

Abstract

Aim. To evaluate the prevalence of the left ventricle remodeling types in hypertrophic non-obstructive cardiomyopathy, and their relation to clinical and instrumental data. Material and methods. Totally 97 patients studied, with hypertrophic non-obstructive cardiomyopathy. Instrumental methods — EchoCG by standard method with assessment of the left ventricle using the myocardial mass index and values of relative wall thickness, and relative thickness index of the walls. Results. In 59% cases hypertrophy of myocardium was localized in the area of interventricular septum, in 18% cases it also involved the apex of the left ventricle, in 22% — spread myocardial hypertrophy. In hypertrophic non-obstructive cardiomyopathy there was the predominance of less benign concentric hypertrophy (in 75-80% of patients) with significant asymmetry of hypertrophy. With the aim to assess the type of remodeling it is recommended not only to measure the relative thickness index, but also more traditional parameter of relative walls thickness.
