Echocardiographic deformation imaging reveals preserved regional systolic function in endurance athletes with left ventricular hypertrophy

Background Left ventricular hypertrophy (LVH) is often observed in athletes, which should be differentiated from hypertrophic cardiomyopathy. The aim of the study was to explore the functional changes measured using tissue Doppler imaging (TDI) deformation analysis in athletes fulfilling LVH criteri...

Description
Summary:Background Left ventricular hypertrophy (LVH) is often observed in athletes, which should be differentiated from hypertrophic cardiomyopathy. The aim of the study was to explore the functional changes measured using tissue Doppler imaging (TDI) deformation analysis in athletes fulfilling LVH criteria participating in different endurance sports. Methods Healthy controls (n = 62, 58% men) and endurance athletes (n = 120, 62% men) aged 18–40 years were prospectively enrolled and underwent both standard echocardiography as well as TDI. Longitudinal TDI-derived strain and strain rate (SR) were calculated in the septal and posterior wall in three segments. LVH was defined as a left ventricular mass (LVM) over 132 g/m2 in men and over 109 g/m2 in women. Results Echocardiographic LVH was observed in 33 athletes (67% men). LVM was significantly increased in both athlete groups (102.6 g/m2 (SD 16.0) and 135.7 g/m2 (SD 15.9) vs 88.0 g/m2 (SD 16.5) in controls, p
