心脏猝死(SCD)为慢性心力衰竭(HF)者的常见并发症,因此预测中重度慢性HF者继发SCD风险尤显重要。既往研究显示,血中可溶性ST2(白介素-1受体家族成员之一)水平升高与急性HF者远期不良预后增加有关。然而关于血中可溶性ST2(sST2)可否预测慢性收缩功能不全性HF者继发SCD风险尚不清 Sudden death from the heart (SCD) is a common complication of chronic heart failure (HF), so it is particularly important to predict the risk of secondary SCD in moderate to severe chronic HF. Previous studies have shown that elevated levels of soluble ST2, a member of the interleukin-1 receptor family, are associated with increased long-term poor prognosis in acute HF. However, it is unclear whether the blood-soluble ST2 (sST2) predicts the risk of secondary SCD in patients with chronic systolic dysfunction
