Light chain amyloidosis (AL) is associated with high mortality. The aim was to identify echocardiographic parameters that predict AL long-term mortality. 42 biopsy-proven AL subjects (43% females; 61±12 years) had echocardiography and followed 29±16 (median 29.4) months. Standard echocardiographic and clinical parameters and heart failure (HF) class were tested using univariate/multivariable Cox proportional hazard regression analyses to identify markers of mortality. 23 subjects died with 1-year mortality of 44%. Univariate predictors of mortality were HF class (p<0.001), left ventricular systolic ejection time (ET, p=0.002), alkaline phosphatase (p<0.001), aspartate and alanine aminotransferase (p=0.003 each). On multivariable analysis, only HF Class (hazards ratio, 95% confidence interval, p-value: 4.86, 1.58-14.9, p=0.006), ET (10 ms increase, 0.87, 0.78-0.97, p=0.01) and alkaline phosphatase (10 U/L increase, 1.04, 1.01-1.06, p=0.01) were prognostic. ET≤240 ms had sensitivity/specificity of 61/90% in predicting 1-year mortality and 73/90% in predicting 1-year cardiac mortality. AL amyloidosis was associated with high long-term mortality. Among echocardiographic and clinical parameters, only ET and alkaline phosphatase had incremental value to HF class in predicting mortality. This may be useful to identify high-risk patients.
