摘要Objective: To investigate the effect of Bushen Hemai decoction on the wall stiffness of middle-aged and elderly patients with simple systolic hypertension. Methods: The 126 middle-aged and elderly patients with simple systolic hypertension admitted to our hospital from May 2010 to May 2015 were randomly divided into control group (63 cases) and observation group (63 cases). The control group was treated with conventional Western medicine, while the observation group was treated with Bushen Hemai decoction on the basis of the control group. The two groups were treated for 4 weeks. Results: The systolic blood pressure of the two groups decreased after treatment (observation group: T=16.165, control group: T=13.537, P<0.05); the systolic blood pressure of the two groups did not change significantly after treatment (observation group: T=1.857, control group: T=0.483, P>0.05); the systolic blood pressure of the observation group was lower than that of the control group after treatment (T=16.165, P<0.05). After treatment, the level of ST segment of ECG in the two groups was lower than that before treatment (observation group: T=22.145, control group: T=11.007, P<0.05); after treatment, the level of ST segment of ECG in the observation group was lower than that in the control group (T=8.130, P<0.05). After treatment, the pulse conduction velocity of the two groups was lower than that of the control group (observation group:T=8.694, control group: T=3.944, P<0.05); after treatment, the pulse conduction velocity of the observation group was lower than that of the control group (T=5.326, P<0.05). The total effective rate of the observation group (93.65％) was higher than that of the control group (76.19％) (P<0.05). Conclusion: Bushen Hemai Decoction has a significant clinical effect on middle-aged and elderly patients with simple systolic hypertension, and can improve the stiffness of the tube wall, which is worthy of clinical reference.
