目的探讨慢性心衰(CHF)患者接受优化药物治疗后症状缓解期血压(BP)水平与预后的关系。方法记录315例CHF患者入院时及症状缓解期的血压水平、血肌酐值、血红蛋白值和心超检查相关数据等,随访至少一年的全因死亡率。结果经Logistic回归分析显示症状缓解期收缩压(SBP)低是死亡率较高的因素(P=0.027),在LVEF减低性心衰(HFrEF)患者中,症状缓解期SBP与死亡呈负相关。结论症状缓解期SBP低是CHF患者死亡的预测因素,尤其是HFrEF患者。
Objective To investigate the relationship between blood pressure (BP) and prognosis in patients with chronic heart failure (CHF) after optimal drug treatment. Methods The blood pressure, blood creatinine, hemoglobin and cardiac ultrasonographic data of 315 patients with CHF at admission and symptom relief were recorded and all-cause mortality was followed up for at least one year. Results Logistic regression analysis showed that low systolic blood pressure (SBP) during remission was a high mortality factor (P = 0.027). SBR was negatively correlated with death in patients with LVEF and HFREF. Conclusions The low SBP level during the remission period is a predictor of mortality in CHF patients, especially HFrEF patients.
