Study On Cardiopulmonary Function Related Parameters Of Patients With Heart Failure Monitored By Ultrasound

Objective: At present,pulse-induced continuous cardiac output monitoring(PICCO)is often used in clinical practice for heart failure volume management.The development of ultrasound technology in recent years has made it play an important role in the evaluation and treatment of patients with heart failure,This article compares ultrasound and PICCO to evaluate the related indexes of heart and lung function in patients with heart failure,assess the consistency and correlation between the two,and explore the value of ultrasound application.Methods: A total of 62 patients with acute heart failure who were admitted to the Department of Cardiology of Xinjiang Uygur Autonomous Region People’s Hospital from March 2018 to September 2019 were selected.Cardiac output(CO),cardiac output index(CI),stroke volume(SV),and B-line scores were monitored by bedside ultrasound immediately at admission(0h),24 h,and 48 h.At the same time,PICCO was used to monitor cardiac output(CO),cardiac output index(CI),stroke volume(SV),and extravascular lung water index(EVLWI).The differences in the indicators of the two methods were compared.Results: There were no significant differences in the SV,CO and CI between two methods at each time point with P>0.05.In addition,the EVLWI measured by PICCO and the B-line score obtained by ultrasound were positively correlated overall(r = 0.823,P < 0.01)and at most of the time points.The ROC curve showed that the area under the curve was 0.822,and the 95% confidence interval was(0.763,0.881).When the B-line score was 28.5,the sensitivity and specificity of EVLWI predicted by B-line were 0.765 and 0.746.Conclusion: The B-line score is positively correlated with EVLWI,and has a higher application value in the assessment of pulmonary edema of acute heart failure.Ultrasound can be used as a complementary method to assess cardiopulmonary function in patients with heart failure.
