RESUMO
AIM To investigate the role of ginkgolide B on the ventricular wall motion and systolic function in acute myocardial infarction (AMI) patients after their revascularization.METHODS A total of 80 cases of AMI patients who underwent revascularization were divided into control group and ginkgolide B treatment group,with 40 patients per group.The two groups of patients both treated basically with routine western medicine were dosed with either placebo or ginkgolide B for 3 months.The cardiac function,normal myocardial percentages,ventricular wall motion,longitudinal peak systolic strain (LPSS) and rate (LPSSR) were evaluated by dobutamine stress echocardiography and these indexes were compared.RESULTS Compared to the control group,left ventricular ejection fraction (LVEF) (66.06 ± 8.39 vs.60.45 ± 13.35,P ＜0.05) and normal myocardial percentages (86.88 ±8.76 vs.79.84 ± 12.25,P ＜0.01) were significantly improved at the 2nd week in ginkgolide B treatment group,but no significant difference on ventricular wall motion was observed'between the two groups (P ＞ 0.05).For the patients with anterior wall AMI,the minus LPSS and LPSSR at basal,middle and apex segment were significantly improved at the 2nd week in ginkgolide B treatment group compared to the control group (P ＜ 0.05,P ＜ 0.01).Moreover,LPSS at apex segment was significantly improved at the 3rd month in ginkgolide B treatment group compared to the control group (P ＜ 0.05).For the patients with inferior wall AMI,minus LPSS at basal and apex segment were significantly improved at the 2nd week and the 3rd month in ginkgolide B treatment group compared to the control group (P ＜ 0.05),whereas minus LPSSR at basal and middle segment at the 2 nd week and basal segment at the 3rd month were significantly improved in ginkgolide B treatment group compared to the control group (P ＜0.05).CONCLUSION Revascularized AMI patients treated with ginkgolide B can expect an improved ventricular wall motion.
