The success rate of heart transplantation varies from person to person and there are no clear data to support this. The peak of rejection after heart transplantation occurs at about 1 month and then declines gradually. The more common causes of graft failure within 1 year are acute rejection or infection, and after 1 year it is mostly coronary vasculopathy or lymphocytosis, with variations in graft success rates. Generally within 1 year of heart transplantation some patients will experience at least one rejection, most patients have no obvious discomfort, and a small number of patients may experience left ventricular dysfunction, arrhythmias, and other cardiovascular system manifestations. Patients who survive >1 year after heart transplantation usually have a good functional recovery status but still have lower than normal exercise levels, and it is possible that cardiac function will gradually improve over time. Patients who want to have a heart transplant are advised to go to a regular hospital, consult a specialized doctor, and cooperate with the doctor to complete the relevant examinations to avoid blind treatment.
