Longitudinal 2D strain at rest predicts the presence of left main and three vessel coronary artery disease in patients without regional wall motion abnormality

Abstract

PSLS at rest was significantly lower in patients with left main or three-vessel CAD without RWMA, and might be useful for identifying patients with a severe CAD.

Carotid Artery Intimal-Medial Thickness and Left Ventricular Longitudinal Systolic Strain in Patients with Coronary Artery Disease

“…We found that GLS declined incrementally with increasing severity of CAD defined by increasing number of stenotic coronary vessels. This finding was similar to results of Biering-Soerensen et al [17] and also the studies reported by Gaibazzi et al [20] and Choi et al [22] which showed similar GLS values through different CAD categories. Patients with normal coronaries had a mean GLS of -22 ±1.5%, single or double vessel disease -19.4 ± 2.4 %, and triple-vessel or left main disease -18 ± 2.3%.…”

“…blood pressure) during image acquisition [21], by using different equipment, different design, vendor-dependent 2D-STE software and operator skills [16,22,23]. Another data have indicated that GLS is more dependent on the 2D-STE software used, rather than ultrasound equipment used to acquire images [24][25][26]; which makes the use of vendor-independent software particularly attractive to standardize GLS for widespread use.…”

The Value of Longitudinal Strain versus Coronary Angiography in Detection of Coronary Artery Disease

“…In another study of 108 patients undergoing coronary angiography, a 2-D longitudinal strain of (−17.9%) discriminated severe 3-vessel or left main disease from lesser coronary artery disease with a sensitivity and specificity of 79% and 79%, respectively [19]. Finally, in a cohort of patients with normal ejection fraction at increased atherosclerotic risk and/or with stable chest pain, a progressive impairment of 2-D global strain and SR (the former with lower variability and higher reproducibility than the latter) was directly related to increasing severity of coronary disease as determined from multislice computed tomography.…”

Speckle tracking echocardiography derived systolic longitudinal strain is better than rest single photon emission tomography perfusion imaging for nonviable myocardium identification

“…In individuals with chronic ischemic heart disease, STE derived parameters correlate with the extent of affected coronary arteries, predict the recovery of the LV function after surgical revascularization, and are capable of differentiating potentially viable segments from those showing scar extent above 50% (ref. [8][9][10] ). However, these segments can display even more than 30 percent of the functional recovery after revascularization 11 .…”
