轻链淀粉样变性(AL)与高死亡率相关。目的是确定预测AL长期死亡率的超声心动图参数。42例经活检证实的AL受试者(43%女性; 61±12岁)接受了超声心动图检查,随访29±16(中位数29.4)个月。采用单变量/多变量考克斯比例风险回归分析对标准超声心动图和临床参数以及心力衰竭(HF)分级进行了检验,以确定死亡率标志物。23例受试者死亡,1年死亡率为44%。死亡率的单变量预测因子为HF分级(p<0.001)、左心室收缩期射血时间(ET,p=0.002)、碱性磷酸酶(p<0.001)、天冬氨酸和丙氨酸氨基转移酶(p=0.003)。在多变量分析中,仅HF分级(风险比,95%置信区间,p值:4.86,1.58-14.9,p=0.006)、ET(10 ms增加,0.87,0.78-0.97,p=0.01)和碱性磷酸酶(10 U/L增加,1.04,1.01-1.06,p=0.01)具有预后性。ET≤240 ms预测1年死亡率的敏感性/特异性为61/90%,预测1年心源性死亡率的敏感性/特异性为73/90%。AL淀粉样变性与高长期死亡率相关。在超声心动图和临床参数中,只有ET和碱性磷酸酶对HF分级有预测死亡的价值。这可能有助于识别高风险患者。
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.
