Abstract

Doppler guidewire studies demonstrated that the no-reflow phenomenon in acute myocardial infarction is associated with characteristic coronary blood flow pattern. We investigated the potential of coronary flow measurement with transthoracic Doppler technique to detect the no-flow in the patients with reperfused infarction, and compared it to that of other modalities.We performed intracoronary myocardial contrast echocardiography after successful primary coronary intervention in the 94 patients with first, anterior wall infarction. Coronary blood flow in the left anterior descending artery was detected with transthoracic Doppler echocardiography within 24 h after reperfusion in 83 patients (88.3%). Twenty-two patients with the no-reflow had significantly lower systolic peak velocity (5.1 ± 4.2 vs. 8.1 ± 6.2 cm/s, p = 0.04), higher diastolic peak velocity (38.2 ± 10.3 vs. 30.8 ± 15.7 cm/s; p = 0.04), and shorter diastolic deceleration time (134 ± 41 vs. 424 ± 202 ms; p <0.0001) than those with good-reflow. Systolic flow reversal was more frequently observed in those with no-reflow (18.2% vs. 3.3%, p = 0.02). Diastolic deceleration time
