Left Ventricular Twisting Modifications in Patients with Left Ventricular Concentric Hypertrophy at Increasing After-Load Conditions

AimsLeft ventricular hypertrophy (LVH) develops as a result of several clinical conditions, such as intensive training, hypertension, aortic valve stenosis. Aim of this study was to analyze the left ventricular twist (LVT) modifications in LVH patients with increasing after‐load conditions. Methods...

Description
Summary:AimsLeft ventricular hypertrophy (LVH) develops as a result of several clinical conditions, such as intensive training, hypertension, aortic valve stenosis. Aim of this study was to analyze the left ventricular twist (LVT) modifications in LVH patients with increasing after‐load conditions. Methods A total of 131 patients were enrolled: 17 healthy sedentary people (Hg), without concentric LVH; 45 water polo players (ATg); 22 patients with hypertensive cardiopathy (HPg); 47 patients with different degrees of aortic stenosis (ASg); all patients had concentric LVH, ejection fraction (EF) >54%, and were age‐matched. The left ventricular end‐systolic wall stress (LV‐ESWS) was used as index of after‐load. Results Left ventricular twist value showed a progressive increase from ATg to ASg, according to increasing after‐load. Longitudinal left ventricular function by tissue Doppler imaging (TDI) and speckle tracking echocardiography (STE) was reduced in HPg and ASg. There was a negative correlation between LVT and longitudinal systolic function at TDI and STE (r = −0.4; P
