Abstract

Background: Coronary artery disease (CAD) early diagnosis remains a clinical problem in patients with non-ST elevation acute coronary syndrome (NSTE-ACS), especially in the regional wall motion abnormalities’ absence on presentation by Echo. This study assessed the relationship between ECG changes and speckle Tracking in subjects with acute NSTE-ACS.

Methods: This prospective trial was performed on 100 subjects with NSTE-ACS. All subjects were subjected to laboratory tests [complete blood picture, renal function test, liver test profile, lipid profile, RBS and cardiac biomarkers (cardiac troponin, creatinine kinase and CK-MB)], 12 lead ECG, Echocardiography (TTE, speckle tracking), Image analysis and coronary angiography.

Results: regarding IVRT, TDI e`, TDI a`, a considerable difference between the two groups were found. DBP was considerably lower in STD group in comparison with TWI group (P value= 0.047). IVRT, TDI a` and GLS were considerably higher in STD group in comparison with TWI group (P value= 0.024, 0.031, 0.003 respectively).

Conclusions: Speckle tracking could be used as part of standard echo for the examination of individuals suffering from NSTE-ACS.
