Correlation between myocardial deformation on three‐dimensional speckle tracking echocardiography and cardiopulmonary exercise testing

Purpose Heart failure (HF) is a multifactorial entity that combines derangements in both systolic and diastolic function. The relationship between systolic and diastolic function and exercise capacity is not fully understood. We sought to determine the mechanisms linking cardiac function and exercis...

Description
Summary:Purpose Heart failure (HF) is a multifactorial entity that combines derangements in both systolic and diastolic function. The relationship between systolic and diastolic function and exercise capacity is not fully understood. We sought to determine the mechanisms linking cardiac function and exercise tolerance in patients with HF. Methods One hundred fifty‐six subjects with different cardiac function levels were included in the study. Subjects’ 2D echocardiographic, 3D speckle tracking echocardiographic, and cardiopulmonary exercise testing (CPET) data were collected. Result The amount of untwisting at 25% of the untwist duration (25%Untwist) and global longitudinal peak systolic strain (GLS) showed the best positive correlations with peak oxygen uptake (peakVO2) (r = .41; P
