Huatan Dingji Decoction intervening in atrial fibrillation: protocol for a randomized double-blind single-simulated placebo-controlled clinical trial
Abstract
Abstract Background Atrial fibrillation (AF) is one of the most common cardiac arrhythmias and can lead to heart failure (HF), stroke, pulmonary embolism (PE), and other complications, seriously affecting people’s quality of life and health. Western medicine is limited in the treatment of AF, while Traditional Chinese Medicine (TCM) has unique advantages, such as less side effects, low toxicity, long effect duration, and high compliance. The prescription of HTDJ is a common prescription for the treatment of atrial fibrillation in Longhua Hospital, Shanghai University of Traditional Chinese Medicine. It has been used for many years and has a large number of clinically effective cases. It has a good clinical application prospect, but there is a lack of effective evaluation of its clinical efficacy. Method This study adopts a randomized double-blind, single-simulated, placebo-controlled research method. Participants were randomly assigned in a 1:1 ratio through a centrally controlled, computer-generated, simple randomization schedule. Participants would take the medicine for 1 month, and the curative effect would be evaluated. Subsequently, the participants would not take TCM and only receive western medicine treatment. They would be followed up for another 8 weeks, and a clinical evaluation would be conducted. The secondary outcomes include echocardiography, Hamilton Anxiety Scale, Hamilton Depression Scale, rate of increase and decrease of anti-arrhythmia western medicine, the MOS 36-item short-form health survey, N-terminal-pro hormone B-type natriuretic peptide level, and integral TCM syndrome score. Adverse events will be monitored throughout the trial. Cases are from outpatient and inpatient with atrial fibrillation in the Cardiology Department of Longhua Hospital. Evaluations will be conducted at baseline and at weeks 4 and 12 after randomization. Discussion In this study, the efficacy and safety of HTDJ plus western medicine in the treatment of atrial fibrillation (qi deficiency and phlegm opacities) will be evaluated, so as to provide medical evidence of short-term and medium-term clinical efficacy for the treatment of atrial fibrillation with integrated traditional and western medicine and lay a foundation for further clinical development and application.
