Background: Coronary artery disease is a major public health problem. Early diagnosis and treatment of coronary artery disease is crucial. There is a need for a practical, reliable and cost-effective non-invasive imaging tool. We aimed to evaluate the rest ischemia with speckle tracking echocardiography (STE) compare to the two methods in patients who were scheduled coronary angiography according to the stress tests. Methods: We included fifty patients with stable angina pectoris who were scheduled for conventional coronary angiography after the stress tests in our study. Speckle tracking echocardiography was performed just before coronary angiography. The association of 2 parameters with coronary artery disease was investigated and compared. Results: Among 50 patients recruited for the study, 38 of them had severe CAD (>50%), whereas 12 patients had non-significant CAD. Post systolic shortening (PSS) was significantly related with CAD (p<0.0001). The relationship of PLS with the area at risk was found to be statistically insignificant but global longitudinal strain (GLS) was significantly lower in patients with severe CAD (p=0.011) Conclusion: PSS may detect coronary ischemia in patients with stable coronary artery disease and it is more sensitive and specific in patients with stable CAD. PSS is a very useful, practical and easy applicable non invasive tool for the detection of severe coronary artery disease at rest.
