Abstract : Background: Immunoglobulin light chain amyloidosis (AL amyloidosis) is a monoclonal plasma cell proliferative disorder that is characterized by tissue deposits of misfolded insoluble κ and λ light chain derived amyloid fibrils, leading to organ dysfunction. The prognosis of patients depends on the number and severity of organ involvement, especially cardiac involvement. Nearly half of the patients with amyloidosis die within a year of diagnosis. We analysed factors predicting early mortality (within one year) in patients with systemic immunoglobulin light chain cardiac amyloidosis.Methods: Retrospective analysis of patients between January 2007 and January 2016 from our hospital database. In patients with AL cardiac amyloidosis, cardiac involvement was defined as per American society of echocardiography (ASE) criteria. We evaluated the clinical, ECG and ECHO parameters of early relapse (ER) within one year in these cardiac AL amyloidosis patients. Log rank test was done to identify independent predictors of one year all cause mortality.
