Clinical Observation of Qinlian Qingxin Decoction in the Treatment of Unstable Angina Pectoris of Phlegm-heat Intermingled Type
Objective:To observe the clinical effect of Qinlian Qingxin Decoction in the treatment of unstable angina pectoris of phlegm-heat accumulation type.Methods:From January 2022 to January 2023,80 patients with UA of phlegm-heat type who were treated in the Department of Cardiology,Hunan Provincial Hospital of Traditional Chinese Medicine were randomly divided into control group and observation group,with 40 patients in each group.The control group was given routine treatment,and the observation group was treated with Qinlian Qingxin Decoction on this basis.The TCM symptom scores,weekly nitroglycerin dosage,weekly angina pectoris duration,TC,LDL-C and CIMT were compared between the two groups.Results:After treatment,the scores of TCM symptoms in the observation group were lower than those in the control group(P<0.05).The weekly nitroglycerin dosage and weekly duration of angina pectoris in the observation group were lower than those in the control group(P<0.05).The levels of TC and LDL-C in the observation group were lower than those in the control group(P<0.05).The CIMT of the observation group was lower than that of the control group(P<0.05).Conclusion:On the basis of conventional treatment,Qinlian Qingxin Decoction can reduce the clinical symptoms of UA patients with phlegm-heat accumulation,improve clinical efficacy,reduce blood lipid levels,delay the progression of atherosclerosis,and reduce plaque formation.
