  1. Data are presented as mean ± standard deviation; LVMI left ventricular mass index; ASE American Society of Echocardiography; Th Teichholz.; Q quartile; LVH left vetricular hypertrophy. The P value between both echocardiographic formulas is depicted in the right-hand column; a significant difference between echocardiographic and CMR measurements was indicated by *** P < 0.001, ** P < 0.01, and * P < 0.05; the overall comparison of quartiles was performed by single factor variance analysis.
