Abstract

Aims The aim of this study was to determine whether myocardial velocity gradients assessed by M-mode colour Doppler tissue imaging could be of clinical relevance and represent reliable indicators of regional left ventricularfunction after acute myocardial infarction. Methods and Results Among 64 consecutive patients with a first acute myocardial infarction, in 50 who had a marked asynergy in the parasternal short-axis view at the mid-papillary muscle level, myocardial velocities and velocity gradients were assessed in the anteroseptum and posterior wall by M-mode Doppler tissue imaging. Similar measurements were obtained in 11 matchedhealthy volunteers who served as a control group. In patients with anterior myocardial infarction, the peak myocardial velocity gradient in the anteroseptum was significantly lower when compared withcontrols (mean +/- [SD] 0.0 +/- 0.5 vs 1.1 +/- 0.7 s(-1) during systole, P< 0.01; and 0.3 +/- 0.6 vs 2.0 +/- 0.5 s(-1) during diastole, P < 0.01). Conversely, the peak systolic myocardial velocity gradient in the posterior wall was significantly higher than in controls (2.6 +/- 1.2 vs 1.8 +/- 1.2 s(-1), P < 0.05). In patients with inferior myocardial infarction, the peakvelocity gradient in the posterior wall was significantly lower when compared with healthy subjects (0.9 +/- 0.6 vs 1.8 +/- 1.2 s(-1) during systole and 1.4 +/- 1.4 vs 4.9 +/- 1.2 s(-1) during diastole, both P < 0.01). The peak systolic tissue velocity gradient in the anteroseptum was significantlyhigher than in controls (2.1 +/- 1.0 vs 1.1 +/- 0.7 s(-1), P < 0.01). Conclusion The present study indicates that myocardial velocity gradients assessed by M-mode Doppler tissue imaging are of clinical relevance for thecharacterization of ischaemic myocardial dysfunction after infarction and may provide quantitative assessment of segmental left ventricular function in this clinical setting.
