ABSTRACT
Objective To observe the clinical efficacy of modified Wendan Decoction combined with amlodipine tablets in treating hypertensive patients with phlegm-damp constitution, and the impact on patients' constitution and vascular endothelial growth factor (VEGF). Methods Totally 126 patients were randomly divided into two groups, 63 cases in each group. The treatment group was given modified Wendan Decoction combined with amlodipine tablets, while the control group received amlodipine tablets, for 12 weeks. The blood pressures, TCM phlegm-damp scores, and serum VEGF levels in both groups were observed before and after treatment. Antihypertensive effect between the two groups was compared. Results TCM phlegm-damp scores decreased significantly in the treatment group after treatment (P0.05). The treatment group was superior to the control group (P<0.01). The systolic blood pressure, diastolic blood pressure, and serum VEGF level significantly decreased after treatment (P<0.01), and the indicators of treatment group were better than those of the control group (P<0.05). The total efficiency of treatment group and control group were 92.1%(58/63) and 76.2%(48/63), respectively, the difference was significant (P<0.05). Conclusion Modified Wendan Decoction combined with amlodipine tablets can significantly improve biased constitution in hypertension patients with phlegm-damp constitution, lower serum VEGF level, and improve endothelial function, with good antihypertensive effect.
