ABSTRACT
Objective To explore the correlation between the characteristics of left atrial(LA)strain and exercise endurance in patients with chronic heart failure(CHF).Methods A total of 212 CHF patients admitted to our hospital from November 2021 to January 2023 were prospec-tively subjected in this study.According to their maximal oxygen uptake(VO2max),they were di-vided into high endurance group[≥16 ml/(kg·min),125 cases]and low endurance group[<16 ml/(kg·min),125 cases].The general data and results of laboratory test were analyzed and com-pared between the two groups.Logistic regression analysis was used to analyze the related factors affecting the exercise endurance.Results Significant differences were observed between the two groups in level of NT-proBNP,ratio of early diastolic peak velocity of mitral valve(E)to early di-astolic peak velocity of mitral annulus(e'),E,LVEDVI,LVESVI,LVSVI,LVEF,LVGLS,LA maximum volume index(LAVImax),LA minimum volume index(LAVImin),LA reservoir strain(LASr),LA conduit strain duct strain(LAScd),and LA contractile strain(LASct)(P<0.05).Multivariate logistic regression analysis showed that LASr(OR=0.987,95%CI:1.003-1.029),LAScd(OR=1.177,95%CI:0.688-0.955),LASct(OR=1.341,95%CI:0.507-0.884).NT-proBNP(OR=1.002,95%CI:0.995-1.000),E/e'(OR=1.086,95%CI:1.000-1.183),LVEDVI(OR=1.127,95%CI:0.805-0.936)and LVEF(OR=0.909,95%CI:0.824-1.000)were related factors influencing exercise endurance in CHF patients(P<0.05).Restricted cube chart revealed that there was a significant nonlinear relationship between LASr,LAScd and LASct and exercise endurance in the patients(x2=9.830,16.820,9.080,P<0.05).Conclusion The char-acteristic indicators of LA strain are related to exercise endurance of CHF patients.
