Medicine (Baltimore). 2020 Sep 4;99(36):e21852. doi: 10.1097/MD.0000000000021852.


Introduction: Chronic heart failure has become one of the main diseases endangering human health in the 21st century. It is characterized by high morbidity and high mortality. With the continuous in-depth study of Traditional Chinese medicine, the treatment of heart failure by Tradional Chinese medicine has made significant progress, especially in improving the clinical symptoms of patients, controlling the development of the disease, and improving the quality of life of patients.

Methods/design: This will be a retrospective, single-blind clinical observational study. All participants will receive chronic heart failure routine treatment and care. The researcher will fill in the case information collection form and collect multiple clinical diagnosis and treatment information.

Discussion: At present, there is very little research on the elements of chronic heart failure syndrome, and more exploration and excavation in this area are needed. So we designed this program. We aim to explore the distribution characteristics of Traditional Chinese medicine syndrome elements and combinations of chronic heart failure patients, and analyze the relationship between syndrome elements and related influencing factors.
