Novel stress echocardiographic model incorporating the extent and severity of wall motion abnormality for risk stratification and prognosis

Role of Left Atrial Size in Risk Stratification and Prognosis of Patients Undergoing Stress Echocardiography

“…The stress echocardiogram, with a peak WMSI of 1.0, was considered normal, and those with a WMSI Ͼ1.0 were considered abnormal. Maximal severity of ischemia was the score of the LV wall segment(s) with the greatest value (worst wall motion grade) at peak stress (range 0 to 5) (13). Ischemic extent was the number of new (ischemic) wall motion abnormality during stress that increases in wall motion score of Ն1 (range 0 to 16) (13).…”

Quantitative Three-Dimensional Wall Motion Analysis Predicts Ischemic Region Size and Location

“…Analysis of left ventricular regional wall motion during stress echocardiography has proved to be a useful predictor of coronary artery disease 2, 22, 26, 27 and clinical prognosis 3, 9, 17, 19, 33. Visual analysis provides little quantitative information, is dependent on the level of experience of the observer23, 29, and is subject to high inter-observer variability8.…”

Role of Right Ventricular Wall Motion Abnormalities in Risk Stratification and Prognosis of Patients Referred for Stress Echocardiography

“…Right ventricular wall motion analysis should be routinely performed in patients referred for SE for effective risk stratification. Stress echocardiography is routinely used for risk stratification and prognosis of patients with known or suspected coronary artery disease (CAD) (1)(2)(3). Conventional stress echocardiography evaluates stress-induced wall motion abnormalities of the left ventricle (LV).…”
