Effects of Danhong injection on cardiac function and blood lipid in patients with angina pectoris of coronary heart disease: A protocol for randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND

Angina pectoris of coronary heart disease is the leading cause of death worldwide. Danhong injection is a supplement for angina pectoris of coronary heart disease. A large number of studies have confirmed its efficacy and safety. However, there is no rigorous clinical study to evaluate the effects of Danhong injection on cardiac function and blood lipid in patients with angina pectoris of coronary heart disease.

METHODS

This is a prospective, randomized, double-blind, placebo-controlled trial to study the effects of Danhong injection on cardiac function and lipid profile in patients with angina pectoris of coronary heart disease. Participants will be randomly divided into treatment group and control group. The treatment group will be treated with Danhong injection and the control group will be treated with placebo under basic treatment according to recommended guideline, and followed up for 3 months after 14 consecutive days of treatment. Outcomes include: cardiac function (left ventricular end-diastolic diameter); left ventricular end-systolic diameter; left ventricular ejection fraction, blood lipid levels (total cholesterol; triacylglycerol; low density lipoprotein cholesterol; high density lipoprotein cholesterol), the number of angina attacks per week, total amount of nitroglycerin tablets, and adverse reactions.

DISCUSSION

This study will evaluate the efficacy of Danhong injection in improving cardiac function and blood lipid in patients with angina pectoris of coronary heart disease. The results of this study will provide reference for clinical use of Danhong injection to improve cardiac function and blood lipid in patients with angina pectoris of coronary heart disease.Trial registration: OSF Registration number: DOI 10.17605/OSF.IO/TPZJ5.
