Effect of Chinese herbal medicine for benefiting qi and nourishing yin to promote blood circulation on ventricular wall motion of AMI patients after revascularization / 中国中西医结合杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of Chinese herbal medicine for benefiting qi and nourishing yin to promote the blood circulation (abbr. as CHM) in promoting ventricular wall motion and myocardial contraction in acute myocardial infarction (AMI) patients after revascularization.</p><p><b>METHODS</b>Subjects were 80 AMI patients after revascularization, of those, the 40 patients in the TCM group were treated with Xinyue Capsule and compound Tanshinon Tablet upon the basic conventional Western medical treatment and the other 40 in the control group were given conventional Western medicine alone, the course for them all was 3 months. Cardiac function indexes, including left ventricular ejection fraction (LVEF), wall motion indices, normal myocardial percentage (NMP), longitudinal systolic peak strain (LSPS) and rate (LSPSR), were observed by Doppler ultrasound under dobutamine stress at the 14 days after revascularization and the end of 3-month treatment.</p><p><b>RESULTS</b>Except the 5 cases (3 in the TCM group and 2 in the control group) dropped out in the observation period, the trial was completed in 75 patients totally. LVEF, NMP, minus LSPS of left ventricular anterior apex and inferior basement, minus LSPSR of anterior apex, middle, basement, and minus LSPSR of inferior middle, basement were more significantly increased in Chinese medicinal treatment group than those in the control group at 14-day after revascularization (P < 0.01). The treatment group, minus LSPS and minus LSPSR of the left ventricular anterior apex and the inferior basement were at markedly higher levels compared with the controls at 3-month after revascularization (P < 0.05). Minus LSPSR of the left ventricular anterior apex and the inferior basement in the treatment group at 3-month was higher than that at 14-day after revascularization (P < 0.05).</p><p><b>CONCLUSION</b>CHM combining with conventional Western medicine treatment could improve the left ventricular contractive function and wall motion in AMI patients after revascularization.</p>
