Abstract: | Objective To observe the effects of Chinese drugs for supplementing qi, nourishing yin and activating blood circulation on the myocardial
perfusion in acute myocardial infarction (AMI) patients after revascularization.
Methods Eighty patients with anterior or inferior ventricular wall AMI, who had received revascularization by intravenous thrombolysis
or coronary bypass, were randomized into the treated group and the control group equally, both treated with conventional Western
medical treatment, but combined, respectively, with Xinyue Capsule (心悦胶囊, XYC) plus Composite Salvia Tablet (CST) and placebo
for 3 months. Dobutamine stress echocardiography (DSE) was performed 14 days and 3 months after revascularization, respectively
on every patient to observe blood perfusion extent (b value), myocardial perfusion velocity (k value) and local blood fl ow
volume (k × b) in left ventricular infarction-related vascular segments under stressed state.
Results With 5 cases dropping out in the observation period (3 in the treated group and 2 in the control group), the trial was completed
in 75 patients in total. The 14-day DSE shows that the b value and k × b value of left anterior ventricular wall mid segment
and apex segment, and the k value of apex segment in patients with anterior wall AMI, as well as the b value and k × b of
basal segment in patients with inferior wall AMI in the treated group were significantly higher than those in the control
group (P<0.05 or P<0.01). The 3-month DSE shows that the b value of apex segment, k × b value of basal segment, mid segment and apex segment
of left anterior ventricular wall in patients with anterior wall AMI as well as the b value and k × b value of basal segment
of left inferior ventricular wall in patients with inferior wall AMI were all higher in the treated group than those in the
control group, respectively (P<0.05). The comparison between 14-day DSE and 3-month DSE in the treated group showed that the b value of apex segment of
left anterior ventricular wall in patients with anterior wall AMI and the k × b value of apex segment and mid segment of left
inferior ventricular wall in patients with inferior wall AMI significantly increased along with the on-going treatment (P<0.05).
Conclusion Therapy with Chinese drugs for supplementing qi, nourishing yin and activating blood circulation in combination with conventional
Western medical treatment could obviously improve the blood perfusion at the myocardial tissue level in infarction-related
vascular segments.
