Post systolic shortening

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. Post-systolic shortening (PSS) is observed in both acute and chronic ischaemia, to a lesser degree also in normal myocardium, 2 and has been proposed as a marker of recovery. 3 It has been shown to predict recovery of systolic function in patients with ST segment elevation MI. 4 Strain echocardiography is an … See more Acute myocardial infarction (MI) is often accompanied by impaired regional myocardial systolic function. Patients with non-ST-segment elevation myocardial infarction (NSTEMI) are recommended to undergo coronary … See more Our study demonstrates that in NSTEMI patients with impaired regional systolic function, PSS can predict recovery of systolic function after revascularization.
