The Diagnostic Pattern and Prognosis of Multiple Myeloma Patients With Myocardial Amyloidosis Were Evaluated by NMR Based Metabolomics

Study Overview
=================
Brief Summary
-----------------
In this clinical study, a single-center retrospective cohort study was used to explore the clinical characteristics and risk factors of patients with multiple myeloma myocardial amyloidosis. An exploratory study was conducted to compare the effects of various sublayer factors (M protein, electrocardiogram, echocardiography, CD138, chromosome abnormalities, etc.) on patients' survival. On this basis, a hierarchical diagnostic model (1-2-3-4) for patients with multiple myeloma complicated with myocardial amyloidosis was established based on the phenoomics of NMR and mass spectrometry, and the prognosis was evaluated simultaneously, in order to create an early, non-invasive, sensitive and quantitative diagnostic model for multiple myeloma complicated with myocardial amyloidosis, and lay a foundation for the early application of effective treatment.

Detailed Description
-----------------
The purpose of this study was to collect clinical data of patients with multiple myeloma complicated with myocardial amyloidosis, analyze and collate the data through statistical methods, and explore the clinical characteristics of patients with MM complicated with myocardial amyloidosis, the factors that may lead to the occurrence of myocardial amyloidosis and the differences in the data of cardiac ultrasound and other biochemical tests, so as to evaluate the prognosis of patients. To investigate the clinical features, risk factors and prognosis of patients with multiple myeloma myocardial amyloidosis. The clinical experience of diagnosis and treatment of this complication was summarized. On this basis, a standard database suitable for the northwest population was established based on NMR phenoomics, and a hierarchical diagnostic model (1-2-3-4) was explored for multiple myeloma patients with myocardial amyloidosis, and the prognosis was evaluated simultaneously. In order to establish an early, non-invasive, sensitive and quantitative diagnostic model for multiple myeloma complicated with myocardial amyloidosis, and to provide clinical basis for further research on early diagnosis, early prevention and early treatment of the disease. To provide the basis for individualized stratified prevention and treatment of patients with multiple myeloma myocardial amyloidosis, reduce the family medical burden and related side effects, improve the quality of life of patients with myeloma myocardial amyloidosis, prolong the survival period, and improve the cure rate
