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.
