Comparing of Peak Longitudinal strain and Post Systolic Shortening in detecting ischemia at rest in stable coronary artery disease: an angiography verified study

Abstract Funding Acknowledgements Type of funding sources: None. Background Coronary artery disease is a major public health problem. Early diagnosis and treatment coronary crucial. There need for practical, reliable cost-effective non-invasive imaging tool. We aimed to evaluate the rest ischemia with speckle tracking echocardiography (STE) compare two methods in patients who were scheduled angiography according stress tests. Methods included fifty stable angina pectoris conventional after tests our study. Speckle was performed just before angiography. The association 2 parameters investigated compared. Results Among 50 recruited study, 38 them had severe CAD (>50%), whereas 12 non-significant CAD. Post systolic shortening (PSS) significantly related (p<0.0001). relationship PLS area at risk found be statistically insignificant but global longitudinal strain (GLS) lower (p = 0.011). Conclusion PSS may detect it more sensitive specific very useful, practical easy applicable non invasive tool detection rest.
