Altered Left Ventricular Geometry and Torsional Mechanics in High Altitude-Induced Pulmonary Hypertension: A Three-Dimensional Echocardiographic Study

摘要

Background: Changes in left ventricular ( LV) torsion have been related to LV geometry in patients with concomitant long-standing myocardial disease or pulmonary hypertension ( PH). We evaluated the effect of acute high altitude-induced isolated PH on LV geometry, volumes, systolic function, and torsional mechanics.
