目的：探讨诱发冠心病慢性左心心力衰竭伴肺动脉高血压患者的相关因素。方法回顾性分析冠心病慢性左心心力衰竭伴肺动脉高血压患者的临床资料，分析其诱发的相关因素。结果伴肺动脉高血压的患者纽约心脏病协会（NYHA）分级Ⅰ、Ⅱ、Ⅲ、Ⅳ级分别有0、3、16、39例，不伴肺动脉高血压的患者分别有4、10、9、19例；伴肺动脉高血压患者的左心室舒张末期内径（LVEDd）、左心房内径（LA）、右心室内径（RV）明显高于不伴肺动脉高血压患者，左心室射血分数（LVEF）低于不伴肺动脉高血压的患者，差异均有统计学意义（均 P＜0.01）。结论伴肺动脉高血压的冠心病慢性左心心力衰竭患者心脏扩张较明显，心功能和肝脏功能较差，且临床预后较差。“,”Objective To explore the main factors inducing coronary heart disease patients with chronic left heart failure in patients with pulmonary hypertension.Methods Retrospective analysis of chronic left heart failure of coronary heart disease with force clinical data of patients with pulmonary arterial hypertension,to analyze the related factors to induce the.Results With pulmonary hypertension in patients with New York Heart Association(NYHA) classificationⅠ,Ⅱ,Ⅲ,Ⅳ respectively 0,3,16,39 cases,without pulmonary hypertension patients were 4,10,9,19 cases of patients with pulmonary hypertension;LVEDd,LA,RV was significantly higher than that of without pulmonary arterial hypertension patients,LVEF was lower than that without pulmonary hypertension patients,the difference was statisticaly significant(P<0.01).Conclusion With pulmonary hypertension coronary heart disease patients with chronic left heart failure in patients with obvious dilatation of the heart,cardiac function and liver function is poor,and poor clinical outcome.
