Background: A type of coronary vasculopathy called coronary artery ectasia (CAE), which is identified in around 5% of individuals undergoing coronary angiography, particularly in males, should not be taken lightly. This study used two-dimensional speckle tracking echocardiography (2D-STE) to assess the effect of CAE on left ventricular systolic function (LVSF) by measuring global longitudinal strain (GLS). 
Methods: 30 individuals with ectasia in one or more coronary arteries but no severe coronary artery stenosis served as the ectatic group in this prospective case-control research, whereas 30 individuals with normal coronary angiography results served as the control group. Either typical angina or favourable findings from stress testing served as the justification for coronary angiography.
Results: T The average global peak longitudinal systolic strain (GPLS) was reduced to a greater or lesser extent depending on the number of vessels and segmental areas impacted in the ectatic group. A statistically substantial variation was existed as regard LV internal diameter, all readings of GPLS of the affected segments except for segment 5, (left circumflex artery, right coronary artery, and left anterior descending) segments average. In the GPLS normal group, there was a large rise in single vessel affection, whereas the GPLS abnormal group had a considerable rise in three vessel affection.
Conclusions: A non-invasive imaging technique called 2D-STE that measures longitudinal systolic strain may help identify early signs of left ventricular systolic malfunction.
