Abstract:
Objective:To investigate the predictive value of the ratio of tricuspid annulus plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP) in the progression of heart failure with reduced ejection fraction (HFrEF) patients.Methods:A total of 172 patients with HFrEF in the First Affiliated Hospital of Zhengzhou University from January to December 2022 were prospectively selected. All participants underwent routine echocardiography, the routine cardiac ultrasound parameters, left atrial volume index (LAVi), right ventricular fractional area change (RVFAC) were measured. The ratio of early diastolic velocity E peak of the mitral valve orifice to the early diastolic mean velocity e′ of the mitral valve annulus (E/e′) and TAPSE/PASP were calculated. The online quantitative analysis software of the ultrasound instrument were used to obtain the left ventricular global longitudinal strain (LVGLS), left atrial reservior strain (LASr), left atrial conduit strain (LAScd), left atrial contraction strain (LASct), right ventricular global systolic strain (RVGLS), and right ventricular free wall strain (RVFWS). According to the median of TAPSE/PASP, the patients were divided into TAPSE/PASP≥0.50 mm/mmHg group(group 1, 85 cases) and TAPSE/PASP<0.50 mm/mmHg group(group 2, 87 cases). The endpoint events were recorded. The differences of the above parameters in two groups were compared, the correlation analysis was used to analyze the correlations between myocardial mechanical parameters and TAPSE/PASP. The Kaplan-Merier method was used to draw survival curves, and the Log-rank method was used to compare the differences in survival curves in the two groups. The univariate and multivariate Cox regression models were used to analyze the predictive value of TAPSE/PASP for end-point events.Results:There were no significant differences in age, gender, body mass index, complications and left ventricular end-diastolic volume (LVEDV) between the two groups (all P>0.05). Compared with group 1, patients in group 2 showed a significant decrease in RVFAC and TAPSE (all P<0.05), while the LAVi, left ventricular end-systolic volume (LVESV), right ventricular end-diastolic diameter (RVDd-base), E/e′ and PASP were increased (all P<0.05), the absolute values of LVGLS, LASr, LASct, RVGLS, and RVFWS were significantly decreased (all P<0.05). Correlation analysis showed that LVGLS, LASr, RVGLS, RVFAC and 6-min walking distance were linearly correlated with TAPSE/PASP ( r/ rs=-0.176, 0.181, -0.496, 0.472, 0.421; all P<0.05). The follow-up time was (11.71±1.80) months, and the incidence of death events in group 2 (28.73%) was higher than that in group 1 (10.61%), with a significant difference ( P<0.05). The results of multivariate Cox regression analysis showed that TAPAE/PASP was one of the independent predictive factors for endpoint events in HFrEF patients, with adjusted HR: 0.306, 95% CI=0.141-0.663, P=0.003. Conclusions:TAPSE/PASP can monitor the progression of chronic heart failure and is one of the independent predictive factors, providing a new reference indicator for clinical diagnosis and treatment.
