Have any of the following heart conditions: 1. New York Heart Association (NYHA) stage III or IV congestive heart failure; 2. Myocardial infarction or coronary artery bypass grafting (CABG) within 6 months before enrollment; 3. Clinically significant ventricular arrhythmia, or a history of unexplained syncope (except those caused by vasovagal or dehydration); 4. History of severe nonischemic cardiomyopathy. 7. Known to have active or uncontrolled autoimmune diseases, such as Crohns disease, rheumatoid arthritis, systemic lupus erythematosus, systemic vasculitis, etc.; 8. Hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) positive and peripheral blood hepatitis B virus (HBV) DNA titer is greater than the normal range; hepatitis C virus (HCV) antibody positive and peripheral blood hepatitis C Virus (HCV) RNA titer test is greater than the normal range; human immunodeficiency virus (HIV) antibody positive; syphilis test positive; cytomegalovirus (CMV) DNA test positive; 9. The subject has experienced venous thromboembolic events (eg: pulmonary embolism) and still needs anticoagulation therapy, or meets the following conditions: a. Bleeding with grades 3 to 4 for more than 30 days; b. venous thrombosis Sequelae (such as persistent dyspnea and hypoxia); (Note: although subjects with venous thrombosis but not meeting the above conditions can participate in the trial); 10. Poorly controlled hypertension, defined as systolic blood pressure = 150 mmHg and/or diastolic blood pressure = 90 mmHg (blood pressure values measured based on the average of 3 readings at least 2 minutes apart, blood pressure = 150/90 mmHg at initial screening is acceptable Antihypertensive treatment, screening can be performed if the blood pressure is less than 150/90mmHg and well controlled after treatment); 11. Women who are pregnant or breastfeeding, and male or female subjects who plan to have children within 1 year after receiving CAR-T cell reinfusion; 12.
