Correlation between Global Longitudinal and Circumferential Peak Systolic Strain and Coronary Artery Disease Severity as Assessed by the Angiographically Derived SYNTAX Score

Abstract

he diagnosis of coronary artery disease using echocardio-graphy mostly depends on the detection of left ventricle abnormal wall motion and the assessment of left ventricle ejection fraction. However, there are no abnormal left ventricle wall motions at rest in coronary artery disease patients without a history of myocardial infarction. Significant coronary artery stenosis might cause persistently impaired longitudinal left ventricle function at rest, so 2D speckle tracking echocardiography is more accurate than conventional 2D echocardiography in evaluating the regional and global myocardial function and assessing infarct size, the viability of the infarcted myocardium, and mild changes of myocardial ischemia The current study included 60 individuals who were recruited from Ain Shams university hospitals in the period from March 2020 to December 2020. All patients were recruited from the catheter laboratory suspected to have coronary artery disease indicated for a coronary angiogram and underwent echocardiographic assessment before elective coronary angiography The objective of the study was to assess the correlation between the severity of coronary artery disease as assessed
