To observe the impact of Wuchong Tongluo Capsule on haemorheology and blood lipid metabolism of patients with coronary heart disease and cerebral infarction.Methods:Sixty patients were randomly grouped to receive Compound Danshen Tablet and Wuchong Tongluo Capsule respectively, to compare their therapeutic effects, haemorheological parameters, and blood lipid changes.Results:Without notable untoward action, the total effective rate of Wuchong Capsule was 96.7% compared to 66.6% of the Danshen Tablet (P<0.05). Two groups were significantly different in haemorheological parameters, and blood lipid levels (P<0.05).Conclusion:Wuchong Capsule can significantly relieve syndromes, improve haemorheological parameters, and lower lipid level as well as blood viscosity. By improving ischemia of the heart and brain tissue, Wuchong Capsule is safe and effective for coronary heart disease and cerebral infarction.
