Description
  • The correlation of velocitity in isovolumic contraction phase (Vivc) by color Doppler myocardial imaging (CDMI) with scar after MI is unknown. 57 patients with CHD (EF 33.5+-5%) were examined echocardiographicaly (689 segments) and by MR. Vivc presence was correlated with signs of a scar after MI in all segments. We found larger values of wall thickness (8.2+-2,2vs.7.1+-1.9,p{0.0001), lower values of average late enhancement (LE) extent (1.32+-1.78vs.1.66+-1.98,p=0.041) and LE/wall thickness ratio (20.1+-29.8vs. 29.6+-36.7, p=0.008) in segments with Vivc. Vivc presence in a segment with abnormal wall motion had sensitivity 72.9%, specificity 35.7% in recognizing a segment without a transmural scar (LE/ wall thickness?75%). Vivc absence in a segment with an abnormal wall motion had sensitivity 72.7%, specificity 41.2% in recognizing a transmural scar (LE/wall thickness?75%).
