Application value of noninvasive hemodynamic monitoring in evaluating pulmonary hemodynamic index and ventricular function of HFpEF patients in early stage

Objective:To investigate the value of noninvasive hemodynamic monitoring in evaluating lung hemodynamic indexes and ventricular function in patients with early left ventricular ejection fraction(HFpEF).Methods:A total of 99 patients admitted to the department of Cardiology in our hospital from January 2018 to August 2019 were selected as study subjects.According to Left ventricular diastolic function,they were divided into Left ventricular ejection fraction reserved heart failure(HFpEF)group(n=45)and Left ventricular diastolic dysfunction(LVDD)group(n=44)with no symptoms of heart failure.Immunoradioassay was used to determine the level of Brain Natriuretic peptide(BNP)in all patients,and cardiac ultrasound tissue Doppler and noninvasive hemodynamic monitoring were used to compare the differences between the two groups.Results:The plasma level of BNP in the HFpEF group was significantly higher than that in the LVDD group(P<0.05),and the Left ventricular ejection fraction(LVEF)was significantly lower than that in the LVDD group(P<0.05),while the Left atrial diameter(LAD)and the Left ventricular end-diastolic diameter were obviously below the LVDD group(P<0.05).There was no statistically significant difference between the LVEDd group and the fractional shortening(FS)group(P>0.05).Ventricular ejection Farction(Q-BI),Ventricular ejection Duration index(B-YI),Myocardial tension index(Q-B/B-Y),and Mean pulmonary arterial pressure PAP was significantly higher than LVDD group(P<0.05).Conclusion:Non-invasive hemodynamic monitoring in patients with early HFpEF can accurately assess the changes of pulmonary hemodynamic indicators during disease development.
