Abstract: Objectives: Intense exercise elevates all heart chambers’ dimensions, left ventricular mass (LV mass), and left ventricular mass index (LV mass index). The relationship between increased ventricular arrhythmias and sudden cardiac death with LV dilatation and elevated LV mass has been previously demonstrated.

The Dallas Heart Study. Background—Left ventricular hypertrophy (LVH) is traditionally classified as concentric or eccentric, based on the ratio of LV wall thickness to chamber dimension. We propose a 4-tiered LVH classification based on LV concentricity0.67 (mass/end-diastolic volume0.67) and indexed LV end-diastolic volume (EDV).

LV ejection fraction (LVEF) was not different among the 6 groups (P>0.05). However, high BMI and poor metabolic health were associated with poorer global longitudinal strain (GLS), higher LV mass index (LVMI) and higher E/e0 (P<0.001). Poor metabolic health status was associated with greater adverse changes in LV structure and function than ...

LV mass was adjusted for BSA (calculated by [weight0.4259height0.725]90.007184).16 We used BSA-adjusted approach defined by indexed LV mass of >125 g/m2 as a cut-off for LV hypertrophy …

the increase in body mass index occurs between the fourth and fifth decades of life, whereas the most prominent in-crease in LV mass occurs later (at age 60 years or older). Thus, if the two factors are causally related, years must elapse before a change in body mass will be translated into changes in LV mass. Further use of regression analysis to

The M mode cube formula takes into account shape distortions caused by valvular disease, such as AR, but not those caused by AS. There are as much data accumulated with 2D mass measurements as there are for M mode measurements. The method produces results which are similar to MRI. The formula used is called the cube formula because linear ...
