摘要
目的探讨肺动脉CT成像在左心收缩功能保留的心力衰竭患者(HFp EF)中的诊断价值。方法利用心脏超声及肺动脉CT成像(CTPA)测定120例HFp EF患者,分为3组:心功能分级Ⅱ级、Ⅲ级、Ⅳ级,对其结果进行分析比较。结果 3组结果显示应用心脏超声测定心功能IV级组E/A与心衰患者分级成正相关性(r=0.92,P<0.05),而EDT、IVRT与心衰患者分级成负相关性(r=-0.81,P<0.05),(r=-0.76,P<0.05)。CTPA结果提示MPAD、r PA、r PD等指标的差异有统计学意义(P<0.05)。而相关性分析提示MPAD、r PA、r PD与心功能III和IV级具有正相关性(P<0.05)。结论肺动脉CT成像技术对左心收缩功能保留的心力衰竭患者诊断具有一定意义,结合心脏超声结果可以提高患者的诊断,为尽早进行干预治疗提供依据。
Objective To explore the diagnostic value of pulmonary artery CT imaging for heart failure with preserved ejection fraction （HFpEF）. Methods 120 patients with HFpEF were divided into 3 groups by echocardiography and pulmonary artery CT imaging （CTPA） based on cardiac function classification： group Ⅱ, group Ⅲ and group Ⅳ and the results among the groups were analyzed and compared. Results The results of echocardiography showed that E/A was positively correlated with the grading of heart failure in group IV （r=0.92, P〈0.05） while EDT and IVRT were negatively correlated with the grading of heart failure （r=-0.81, P〈0.05）, （r=0.76, P 〈 0 .0 5 ） ; the results of CTPA revealed a statistical difference in MPAD, rPA and rPD among the 3 groups （P〈0.05）; the correlation analysis suggested that MPAD, rPA and rPD had a positive correlation with cardiac function Ⅲ and Ⅳ （P〈 0.05）. Conclusions CTPA is of certain diagnostic value for HFpEF, combined with echocardiography, it can promote the correctness of diagnosis and provide basis for early intervention.
