Follow up Study of Crocin on Cardiac Function Protection in Patients With Breast Cancer Undergoing Neoadjuvant Chemotherapy Based on Color Doppler Ultrasound Combined With Myocardial Zymogram

Foreign data show that: 1807 tumor patients were followed up for 7 years, 33% of them died of heart disease and 51% of them died of the tumor itself. In China, the number of cancer patients undergoing chemotherapy is increasing rapidly every year. How to protect the heart of chemotherapy patients from the damage of chemotherapy drugs (especially anthracyclines) is a problem that clinicians must face.In order to further confirm the clinical efficacy and value of saffron total glycosides tablets in the protection of central function of breast cancer neoadjuvant patients with anthracycline based chemotherapy scheme, the project plans to follow up and observe the research of saffron total glycosides on the protection of cardiac function of breast cancer neoadjuvant patients with chemotherapy based on cardiac color ultrasound combined with myocardial zymography, and randomly group to confirm the effectiveness of saffron total glycosides tablets on cardiac protection, Based on the clinical observation and research on the effect of traditional Chinese medicine on the cardiotoxicity of anthracycline drugs, confirm its efficacy, explore the mechanism of cardiac protection, and explore the drug use method of synergism and toxicity reduction of anthracycline drugs in combination with this active ingredient.
