摘要 目的评估左心房功能在射血分数保留心衰患者独立预后的重要性。方法采用散斑跟踪超声心动图检测整个心动周期内的窦性心律,对使用醛固酮拮抗剂螺内酯进行射血分数保留心力衰竭治疗的239例HFPEF患者进行左心房功能评估。结果LA应变峰值越低即LA功能障碍,则患者年龄越大、房颤和左室肥厚发生率越高、左室和右室收缩功能、左室舒张功能越差。29个月的平均随访期(IQR 16-41)中61例患者(25.5%)经历了CV死亡、HF住院治疗和猝死的主要复合终点。LA应变峰值越低,复合终点(HR 0.95,95%CI 0.93~0.98;P=0.008)和HF再住院率(HR 0.94,95%CI 0.91~0.97;P=0.004)的风险越高。在调整临床混杂因子后,LA应变率仍与HF住院治疗显著相关。结论HFPEF患者中LA功能障碍与HF再住院率的高风险相关,且独立于潜在的临床混杂因子。
