Ultrasound Evaluation Of The Incidence Of Abdominal Aortic Plaques And Hemodynamic Changes And Correlation Of Coronary Artery Disease

Objective:Ultrasonic evaluation of abdominal aortic plaques and hemodynamic changes in the incidence of coronary artery disease and correlation between the degree.Methods:Randomly selected in June 2008 to December due to angina pectoris, unexplained chest pain or myocardial infarction in patients undergoing coronary angiography as the research object,according to coronary artery obstruction count into the normal coronary group,single vessel double vessel disease and vascular disease over groups:normal control group,48 patients,26 males and 22 females, aged 48 to 83 years, mean age (64.5±4.6) years; single-vessel disease,46 cases,26 male 20 female, aged 43 to 81 years old, mean age (61.8±8.3) years; double vessel disease group more than 51 patients,28 males and 23 females, aged 45 to 79 years, mean age (65.2±7.9) years. Age and sex of each group no significant difference.U.S.GE vivid 7 with color ultrasound diagnostic apparatus,two-dimen-sional ultrasound observation of abdominal aorta is focused on smooth plaques lining the existence of color Doppler ultrasound color when observed in the abdominal aorta with or without filling defects,to lumen containing a wall plaque exclusion. And take the pulse Doppler measurement of peak systolic flow velocity spectrum (PSV), end diastolic velocity (EDV), pulsatility index (PI), resistance index (RI) and blood flow (Volflow) and other hemodynamic parameters.Results:48 cases of normal control group,5 patients can explore and plaque (5/48,10.4%).46 patients with single vessel disease in 12 patients and plaque could be detected (12/46,26.1%), the incidence of plaque compared with normal control group was statistically significant (P<0.05). Double vessel disease group than there were 20 cases 51 cases and plaque could be detected (20/51,39.2%), plaque and the incidence of single-vessel disease and normal control group were significantly higher, statistically significant (P<0.005).More than double vessel coronary artery disease group, the aorta reduced PSV, PI, RI increased compared with single-vessel disease was significantly (P<0.05),compared with the control group, PSV was significantly reduced, PI, RI were significantly higher statistically significant(P<0.05);single vessel disease group than the control group reduced PSV, PI, RI increased significantly (P<0.05). Single-vessel disease, double vessel disease group than the EDV and Volflow compared with the control group was not significant (P>0.05).Severity of coronary artery disease and abdominal aortic blood flow parameters of PSV, PI and RI and the incidence of plaque has a good correlation. EDV and Volflow not found a correlation between.Conclusion:The incidence of abdominal aortic plaques and blood flow increased gradually to reduce the PSV, PI and RI increased with the evolution of coronary artery disease with consistent,comprehensive analysis of both the degree of coronary artery disease can prompt a better predictive value.
