The Effect of Modified Shugan Dingji Decoction(疏肝定悸汤)on the Occurrence of Endpoint Events in Patients with Paroxysmal Atrial Fibrillation of Liver Constraint and Qi Stagnation:A Retrospective Cohort Study
Objective To retrospectively analyze the effect of modified Shugan Dingji Decoction(疏肝定悸汤)on the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation.Methods A retrospective cohort study was conducted using the electronic medical record database of Longhua Hospi-tal affiliated to Shanghai University of Traditional Chinese Medicine to screen and include patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation from January 1st,2018,to December 31th,2021.The included patients were divided into an exposure group and a non-exposure group,each consisting of 100 cases,based on whether they received modified Shugan Dingji Decoction.General information of the patients including age,gender,body mass index,duration of illness and comorbidities,medication history,cardiac structure and function indicators such as left atrial diameter,left ventricular end-diastolic diameter,stroke volume and ejection fraction,and the occurrence of endpoint events assessed through 24-hour dynamic electrocardiography or electrocardiogram to determine the recur-rence of paroxysmal atrial fibrillation were collected.Kaplan-Meier(K-M)curves and Log-Rank tests were used to conduct survival analysis on the occurrence of endpoint events in the two groups of patients.Univariate and multivari-ate Cox regression analyses were used to analyze the impact of various factors on entry into endpoint events.Addition-ally,a safety assessment was performed by comparing liver and kidney function indicators before and after treatment.Results In the non-exposure group,a total of 49 cases(49.0％)experienced endpoint events,while in the exposure group,there were 26 cases(26.0％).The Log-rank test indicated significant difference between the two groups(x2=11.211,P=0.001).Univariate Cox regression analysis showed that age,duration of illness,hypertension,diabetes,chronic heart failure,left atrial diameter,stroke volume,and the use of modified Shugan Dingji Decoction may be the influencing factors for the occurrence of endpoint events in patients with paroxysmal atrial fibrillation of liver constraint and qi stagnation(P＜0.05 or P＜0.01).Multivariate Cox regression analysis showed that the risk of end-point events in the exposure group was significantly lower than that in the non-exposure group(P＜0.01).Patients with a duration of illness＞12 months had a significantly higher risk of endpoint events compared to those with a duration of illness≤12 months(P＜0.01).Patients without concomitant hypertension had a lower risk of endpoint events com-pared to those with hypertension(P＜0.05).Patients with left atrial diameter＞40 mm had significantly higher risk of endpoint events than those with left atrial diameter ≤40 mm(P＜0.01).There was no statistically significant difference in liver and kidney function indicators between the two groups before and after treatment(P＞0.05).Conclusion The use of modified Shugan Dingji Decoction is a protective factor for patients with paroxysmal atrial fibrillation of liver con-straint and qi stagnation,which can help to reduce the recurrence and progression of atrial fibrillation.Long duration of illness,concomitant hypertension,and enlarged left atrial diameter are risk factors for patients to experience endpoint events.
