摘　　要：目的联合应用射血分数(EF)和心排血指数(CI)评价心血管外科心力衰竭(HF)患者的心脏功能,分析EF、CI与美国心脏病学会/美国心脏学会(ACC/AHA)提出的HF分期的相关性,评估心血管外科患者的心脏功能,指导治疗。方法 2016年3月至2017年3月选取正常对照组15例为A组,健康成年人;哈尔滨市第一医院心内四病房收治的HF患者30例为B组,其中B1组15例EF<50%,B2组15例EF≥50%,分别应用心脏超声和心脏磁共振的方法测量A组、B组所有入选人员的EF、每搏输出量(SV),记录即时心率。记录所有入选人员的身高、体重,计算CI。比较A组EF与CI的相关性。对于B组HF患者,按照AHA/ACC提出的HF分期标准进行分期,分别比较B组患者的EF与CI、EF与HF分期、CI与HF分期的相关性。结果 A组患者的EF与CI无固定关系;B1组患者的EF越低,CI越低,P<0.05;B2组患者的CI降低,EF与CI无明显关系;B组患者根据AHA/ACC提出的HF分期进行分期,C期、D期患者分期越高,CI越低,P<0.05。结论健康人的心脏EF与CI无固定关系;EF<50%的HF患者EF与CI成正相关;EF≥50%的HF患者CI降低,但是无固定关系;根据AHA/ACC提出的HF分期,分期越高,CI越低。Objective To evaluate the cardiac function of patients with heart failure（HF） in cardiovascular surgery combined ejection fraction（EF） and cardiac index（CI）, analyze the relevance between EF, CI and HF stages proposed by American College of Cardiology/American Heart Association（ACC/AHA）. Methods From March 2016 to March 2017, 15 healthy adults were selected as control group and named group A; 30 HF patients in the number one hospital of Harbin were selected as HF group and named group B, including group B1 15 patients with EF 50% and group B2 15 patients with EF ≥ 50%. All persons in group A and group B were measured with EF, stroke volume（SV） and heart rate by echocardiography and cardiac magnetic resonance imaging respectively. All selected persons＇ height and weigh were recorded, and CI was calculated. EF and CI were compared in group A. HF staging of patients in group B were determined which proposed by AHA/ACC. EF and CI, EF and HF staging, CI and HF staging were compared respectively. Results In group A, there was not fixed relationship between EF and CI. In group B1, the lower EF was, the lower CI was, P〈0.05. In group B2, CI decreased, but there was not significance between EF and CI. In group B, the higher staging of C phase and D phase in patients, the lower CI was,P〈0.05. Conclusions EF and CI of healthy heart are not fixed relationship; In the HF patients with EF 50% EF and CI are positively correlated; In the HF patients with EF ≥ 50% CI are lower but there is not fixed relationship; According to the AHA/ACC staging for the HF patients, the higher HF staging is, the lower CI is.
