Actually, the previous treatments focus on improving the symptoms of heart failure and arrhythmia, at present, advanced chemotherapy regimens, immune therapy, stem cell transplantation, regulation of gene expression and more progressive methods are rising up. This paper describes the new research progress of diagnosis, treatment of myocardial amyloidosis.
