To observe the effects of GualouXiebaiBanxia decoction on myocardial revascularization in the treatment of angina pectoris of coronary heart disease and phlegm stagnation syndrome. Methods:A total of 182 cases of angina pectoris of coronary heart disease of phlegm stagnation syndrome hospitalized in our hospital from June 2013 to December 2015 were collected, then equally divided into control group and observation group with 91 patients in each. The control group was given conventional western medicine treatment, on the basis of that, the treatment group were given Gualou Xiebai Banxia decoction. Treatment duration in the two groups were 14 d. Results:After treatment, the total effective rates in the observation group and the control group were 97.8% and 86.8%, and that of the observation group was significantly higher than that of the control group (P<0.05). The dosage of nitroglycerin in the observation group and the control group after treatment were 6.87 ± 2.45 mL and 8.45 ± 2.87 mL, significantly lower than before treatment (12.84 ± 3.09 mL and 12.67 ± 2.89 mL) respectively (P<0.05), while the dosage of nitroglycerin in the observation group after treatment were significantly lower than the control group (P<0.05). After treatment, the compression of brachial artery diameter expansion rates in the two groups were increased significantly, there were statistically significant growth difference in the group, besides, the difference between the two groups was significant (P<0.05). There were no significant difference in resting brachial artery diameter before and after treatment within the two groups (P>0.05). The left ventricular anterior wall of the middle section of the B and K values in the observation group after treatment were 5.45 ± 0.76 db and 1.88 ± 0.25 S′. While the control group were 5.02 ±0.56 db and 1.80 ± 0.21 S′， which is significantly higher than that of the control group (P<0.05). Conclusion:Gualou Xiebai Banxia decoction in the treatment of angina pectoris of coronary heart disease of phlegm stagnation syndrome can reverse differentiation of endothelial cell function, promote myocardial revascularization to improve, thereby reducing the dosage of nitroglycerin and improving the treatment effect.
