Abstract

Since M-mode measurements can assess deformation of specific regions of the left ventricle, we hypothesized that M-mode measurements like M-mode apical systolic excursion (MMASE) and mitral annular plane systolic excursion (MAPSE) may be correlated with left ventricular longitudinal strain (LVLS). All subjects of the study underwent a full echocardiographic evaluation and MMASE and MAPSE measurement. Three-dimensional wall motion tracking (3D-WMT) was performed. Thirty-one patients were evaluated. Significant correlations between MAPSE and LVLS (-0.372; p=0.04) and between MMASE and LVLS (-0.398; p=0.027) were found. LVLS was linearly related to MAPSE and MMASE (in mm) as follows: ST=-10.6 -0.4 * MAPSE (r2=0.14) and ST=-13.1 -0.5 * MMASE (r2=0.16). Our results demonstrate that simpler and faster methods than strain based on complex speckle analysis can also have a role in predicting subclinical left ventricular systolic dysfunction.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
