Evaluation Of Right Heart Function In Patients With Non- ST-segment Elevation Acute Coronary Syndrome By Three-Dimensional Ultrasound Combined With Tei Index

Objective: In this study,three-dimensional ultrasound and Tei index were used to explore the effect of non-ST-segment elevation acute coronary syndrome(NSTE-ACS)on right ventricular function Methods: Analysis the diagnosis of ACS patients,according to the results of the electrocardiogram(ECG)and coronary angiography to collect non ST segment elevation ACS patients and coronary angiography in patients with completely normal,and the echocardiographic examination was carried out,record and store the apex four cavity(4 cardiac cycle heart full volume image)and tissue doppler mode tricuspid travel away from the wall of the movement of the spectrum,in case analysis to find predictable NSTE-ACS positive related indicators.Results:(1)compared with the control group,NSTE-ACS group EDV(P=0.035),NSTE-ACS group ESV(P=0.034),NSTEACS group EF(P=0.000),NSTE-ACS group SV(P=0.000),NSTE-ACS group TAPSE(P=0.003),NSTE-ACS group FAC(P=0.000),NSTE-ACS group RVLSsptum(P=0.002).Compared with the control group,RVLSfree(P=0.003)in NSTE-ACS group and NSTEACS group were compared with the control group.The area under the ROC curve analysis showed: EDV=0.655,ESV=0.647,EF=0.964,SV=0.789,TAPSE=0.714,FAC=0.714,RVLSsptum=0.743,RVLSfree=0.731.Conclusion: Three-dimensional ultrasound and Tei index analysis showed that the right heart function of patients with non-ST-segment elevation acute coronary syndrome was reduced compared with normal people.
