Left ventricular dyssynchrony assessment using tissue synchronization imaging in acute myocardial infarction.

Correlation between conventional echocardiographic and TSI parameters in STEMI group Across the entire study population, we found that there was a highly significant negative correlation between LVEF and TSI parameters, such as septal-lateral wall delay ( r = −0.665; P = 0.0001), septal-posterior wall delay ( r = −0.978; P = 0.0001), all segments maximum difference ( r = −0.557; P = 0.0001), and dyssynchrony index ( r = −0.608; P = 0.0001).
