摘　　要：目的研究射血分数保留型心衰(HFp EF)患者肺动脉CT参数与其NYHA分级的关系。方法选取2020年1月至2022年1月我院收治的射血分数保留型心衰(HFp EF)患者126例患者作为研究对象,利用肺动脉CT成像(CTPA)对所选HFp EF患者进行测定,NYHA分级分为Ⅱ、Ⅲ、Ⅳ级,分析所测定的肺动脉CT参数与NYHA分级之间的相关性。结果根据CTPA结果确定了MPAD、r PA、r PD等指数间的差值,具有重要统计意义(P<0.05)。通过相关性分析,确定了MPAD、r PA、r PD三种参数,与NYHA分级的Ⅲ、Ⅳ级具有正相关性(P<0.05)。结论HFp EF患者肺动脉CT参数MPAD、PA和r PD与NYHA分级Ⅲ、Ⅳ级具有明显相关性可用作预测病变严重程度的重要指标。Objective To study the relationship between CT parameters of pulmonary artery and NYHA grade in patients with ejection fraction preserved heart failure(HFpEF).Methods From January 2020 to January 2022,126 patients with ejection fraction-preserved heart failure(HFpEF)in our hospital were selected as the research object.Pulmonary CT imaging(CTPA)was used to measure the selected HFpEF patients.NYHA classification was divided into II,III and IV grades,and the correlation between the measured pulmonary CT parameters and NYHA classification was analyzed.Results According to CTPA results,the differences among MPAD,rPA,rPD and other indexes were determined,which had significant statistical significance(P<0.05).Through correlation analysis,MPAD,rPA and rPD were determined,which were positively correlated with NYHA grade III and IV(P<0.05).Conclusion MPAD,PA and rPD of pulmonary artery CT parameters in HFpEF patients have obvious correlation with NYHA grade III and IV,which can be used as an important index to predict the severity of lesions.
