Abstract:
Aim To evaluate the right atrial function by two-dimensional speckle tracking imaging(2D-STI)combined with real-time three-dimensional echocardiography(RT-3DE)in patients with triple vessel coronary artery disease(TVCAD)without myocardial infarction.Methods Fifty-six patients with TVCAD without myocardial infarc-tion were selected and divided into two groups according to the results of coronary angiography:28 cases with a stenosis rate of 50％～75％and 28 cases with a stenosis rate of ≥75％.In addition,30 healthy volunteers were screened as control group.RT-3DE was performed to obtain the parameters of right atrial volume(RAVmax,RAVmin and RAVp)and then calculated right atrial passive ejection fraction(RAPEF)and right atrial active ejection fraction(RAAEF),and the maxi-mum of right atrial volume index(RAVImax).2D-STI was applied to measure right atrium strain rates during systole,ear-ly diastole and late diastole(RASRs,RASRe and RASRa).Correlation between 2D-STI parameters and N-terminal pro-brain natriuretic peptide(NT-proBNP),Gensini scores were analyzed by Pearson analysis.ROC curve analysis was used to evaluate the diagnostic value of 2D-STI,RT-3DE,and their combined use for right atrial function in TVCAD patients without myocardial infarction.Results Compared with control group,RAPEF and RASRe reduced in stenosis rate of 50％～75％group,while RAAEF and RASRa increased(all P＜0.05).Compared with control group and stenosis rate of 50％～75％group,RAPEF,RASRs,RASRe and RASRa decreased,while RAVmax,RAVmin,RAVp,RAVImax and RAAEF increased in stenosis rate of ≥75％group(all P＜0.05).There was a significant correlation between 2D-STI pa-rameters and NT-proBNP and Gensini scores.The area under the curve of right atrial function in TVCAD patients without myocardial infarction was 0.9048,0.8917 and 0.9564 for 2D-STI,RT-3DE and their combined use,respectively.The diagnostic efficacy of the two methods was significantly higher when used in combination than when used alone,and 2D-STI was superior to RT-3DE.Conclusion When evaluating the right atrial function of TVCAD patients without myocardial infarction,the diagnostic efficacy of 2D-STI combined with RT-3DE is higher than that of using it alone,and 2D-STI is su-perior to RT-3DE.
