Speckle tracking echocardiography derived systolic longitudinal strain is better than rest single photon emission tomography perfusion imaging for nonviable myocardium identification
Original language description
Background. The aim was to compare the speckle tracking echocardiography (STE) derived systolic longitudinal strain (SLSmax) with rest single photon emission computed tomography (SPECT) perfusion imaging (Q(REST)), and to define the optimal cut-offs forSLSmax to discriminate transmural scar on contrast-enhanced magnetic resonance imaging (ceCMR). Methods and Results. In 100 patients with chronic ischemic left ventricular (LV) dysfunction, myocardial viability was assessed using STE and rest SPECT to predict LV segmental relative extent of delayed enhancement (DE) >75% on ceCMR. Correlation was found between regional SLSmax (r=-0.59, P<0.0001) and DE on ceCMR. The SLSmax optimal cut-off -5.3% identified segments with DE>75% on ceCMR (sensitivity 83.1%, specificity 84.6%). Optimal cut-offs SLSmax for segments corresponding to individual perfusion territories (-3.6%, -5.3% and -4.7% for LAD, LCx resp. RCA perfusion territories) were identified. There was a significant difference
