摘要
目的:探讨心脏彩超中特异性指标在评估肺源性心脏病临床研究价值。方法:将医院收治的62例稳定期慢性肺源性心脏病患者依据住院治疗期间是否出现心脏失代偿临床表现分为代偿组(SP组,51例)及失代偿组(DP组,11例)。于接诊首日采用心脏彩超技术对两组的血管和心脏参数进行评估。Spearman分析法分析上述指标与肺源性心脏病临床的相关性;ROC曲线分析各指标的对失代偿转归的参考价值。结果:SP组患者Nakata指数、左室等容舒张时间、肺动脉压力指标均低于DP组(P<0.05);Mcgoon指数、主动脉瓣口面积、左室射血分数、E波减速时A峰E峰流速比值则升高(P<0.05)。Nakata指数、肺动脉压力与失代偿进展呈负相关;主动脉瓣口面积、左室射血分数、左室等容舒张时间、E波减速时A峰E峰流速比值与慢性肺源性心脏病失代偿进展存在线性正相关;全参数评估病情转归的ROC曲线下面积较优(AUC=0.806)。结论:心脏彩超指标在慢性肺源性心脏病早期病情评估、失代偿恶化进程中,有极高临床参考、应用意义及价值。
Objective:To explore the clinical research value of specific indicators in cardiac ultrasound in evaluating pulmonary heart disease.Method:A total of 62 patients with stable chronic pulmonary heart disease who were diagnosed and treated in hospital were selected.Based on whether there were clinical manifestations of cardiac decompensation during hospitalization,Divided into compensatory group(SP group,51 cases)and decompensation group(DP group,11 cases)On the first day of diagnosis,cardiac ultrasound technology was used to evaluate two sets of cardiovascular and cardiac parameters,including Nakata index,McGoon index,aortic valve area,left ventricular ejection fraction,left ventricular isovolumic relaxation time,A-peak to E-peak flow velocity ratio during E-wave deceleration,and pulmonary artery pressure.Pearson analysis was used to analyze the correlation between the above indicators and the clinical manifestations of pulmonary heart disease;The ROC curve analysis showed that the reference value of various parameter indicators for decompensated outcomes was significantly reduced in the SP group compared to the DP group(P<0.05).Result:Nakata index and pulmonary artery pressure in SP group were significantly lower than those in DP group(P<0.05).Mcgoon index,aortic valve orifice area,left ventricular ejection fraction,left ventricular isovolumic relaxation time and the ratio of A to E velocity during E wave deceleration were significantly increased(P<0.05).Nakata index and pulmonary artery pressure were negatively correlated with the progression of decompensation.Aortic valve orifice area,left ventricular ejection fraction,left ventricular isovolumic relaxation time,the ratio of A peak to E peak velocity during E wave deceleration are positively correlated with the progression of decompensation of chronic pulmonary heart disease.The area under the ROC curve of full parameters was better(AUC=0.856).Conclusion:Cardiac ultrasound indicators such as Nakata index,McGoon index,aortic valve area,left ventricular ejection fraction,left ventricular isovolumic relaxation time,E-wave deceleration,A-peak to E-peak flow velocity ratio,and pulmonary artery pressure have high clinical reference,application significance,and value in the early assessment of chronic pulmonary heart disease and the process of decompensated deterioration.
