Abstract
This study included 14 females (14%) and 86 males (86%) with a mean age 49.85 ± 5.94, including Patients with SCAD and having more than 75% stenosis in at least a vessel with a diameter > 1.5mm.
Our study showed there was significant statistical difference between LAD affection and /or Number of affected vessels and Tie index, GLSS, SYANTAX score.
There was also negative correlation between SYNTAX and GLSS values, while a positive correlation between Tie index, IVRT (r= - 0.313, p<0.01)), (r=0.495, p value<0.01), (r=0.39, p <0.01), respectively,. How ever there was no statistically significant difference between SYNTAX score and all above echo parameters.
the aim of this study is to examine the ability of different echocardiograph modalities to determine the severity of coronary artery disease in patients with stable angina pectoris.
