Balkamra-hipertrófia mértékét jellemző paraméterek összefüggése MRI-vel meghatározott bal kamrai izomtömeggel hipertrófiás cardiomyopathiában

Abstract

The magnitude and distribution of left ventricular hypertrophy (LVH) shows a remarkable variety in patients with hypertrophic cardiomyopathy (HCM). To characterise LVH in HCM, several LVH parameters has been traditionally used in clinical practice. In our study we aimed to look for correlation between traditional LVH parameters and MRI derived left ventricular mass (LVM) in patients with HCM. The patient study cohort included 44 HCM patients (27 males, average age: 43±16 yrs). Cardiac MRI examination was performed according to standard methods and left ventricular mass (LVM MRI ) was deter-mined. Correlation was looked for between LVM MRI and the following left ventricular hypertrophy parameters: maximal left ventricular wall thickness (LV max ), Maron-Spirito score, Weigle score, number of hypertrophized LV segments, and left ventricular mass calculated from echocardiographic parameters, using the Deveraux equation (LVM echo ). LVM MRI has been correlated with the average left ventricular wall thickness (LV average)
