Post systolic shortening
Web19 Oct 2024 · The PSI is associated with most validated echocardiographic and invasive measures of cardiac systolic and diastolic function and was associated with invasively measured LV pressure decline in early diastole and dP/dt min. Post-systolic shortening (PSS) does not contribute to the ejection of blood and may inhibit diastolic filling. We … Web23 Apr 2013 · Post-systolic shortening was considered present in case peak systolic strain occurred after aortic valve closure. 21 For this purpose, aortic valve closure was visually marked in an apical three-chamber view.

WebMyocardial wall thickness and the presence of post-systolic shortening at dyssynergic segments have been found to be useful parameters in identifying viable myocardium. Myocardial necrosis is associated with wall thinning on echocardiography in chronic transmural infarction. Web23 Feb 2024 · Global longitudinal strain at rest (GLSr) and at peak stress (GLSp) and an index of postsystolic (PSSi) shortening ( [maximal extent of shortening – extent of shortening in systole]/ [extent of shortening in systole]) were determined. A PSSi of ≥ 0.25 was considered evidence for CAD.
Web25 Aug 2024 · A greater number of segments with post-systolic shortening was observed in the users of AAS, probably resulting in an increase in wasted energy after the end of blood ejection, which could contribute, at least in part, to the decrease in their LV systolic function. However, further studies will be needed to assess the link between regional ... Webutility of post-systolic shortening and a strain imaging diastolic index for detection of ischemic memory. The study is an extension of previous work published by the same group (9).
