Postmenopausal Women Treadmill Exercise Test Duke Score And Coronary Angiography Correlational Study

Objective:Study on clinical values of treadmill exercise test and duke treadmill score for aided diagnosis of coronary artery disease in post-menopausal women. Methods:In October2009to April2012in Hospital of Chinese Medicine Affiliated to Xinjiang Medical University cardiovascular specialized subject hospitalization for treadmill exercise test and coronary angiography in post-menopausal women with102cases. Among them, treadmill exercise test positive77cases and negative25cases. To coronary angiography compared to treadmill exercise test, and combining to duke treadmill score among post-menopausal women coronary artery disease diagnosis sensitivity and specificity, and do statistics analysis.Result:l. Through the analysis of treadmill exercise test as compared with coronary angiography results, coronary angiography was used as the standard.63of treadmill exercise test had true positive results; accounting for77.4%and16cases had negative results. The sensitivity of Treadmill exercise test was87.5%and the specificity is53.3%. The consistency of the coronary angiography and treadmill exercise test in diagnosing coronary heart disease reached to moderate.2.Compared to duke treadmill score risk degree and coronary angiography, which low risk groups for28of the normal coronary angiography, who not with Multivessel disease. High risk group coronary angiography is abnormal, which group for16of them with Multivessel disease. Duke treadmill score risk degree and coronary angiography pathological damage were related.(rs=0.784, P=0.000).3. Through Compared different time of menopause to the coronary artery branch lesions, Menopause in patients with less than5years had8cases of normal coronary angiography and none of multiple vessel diseases; only one normal coronary angiography and18of multiple vessel diseases on Menopause in patients with more than20years. Coronary bifurcation lesions enhanced with prolonging duration of menopause, Coronary bifurcation lesions correlated with duration of menopause (rs=0.615, P=0.000).4. Through contrasting Different age groups to Duke Score risk degree classification, there were evaluated for3cases low risk and0high risk in35～44years,5cases low risk and21 high risk over65years. Duke score increased risk level as the time increased, Duke Score weakly correlated with duration of menopause.5.Through contrasting duration of menopause to Duke Score risk degree classification, there were8peoples whose duration of menopause greater than5years in Duke score low risk group,1case in in Duke score high risk group;2peoples whose duration of menopause greater than20years in Duke score low risk group,16cases in in Duke score high risk group. Duke score increased risk level as prolonging duration of menopause, Duke Score strongly correlated with duration of menopause.(rs=0.511, P=0.000). Conclusion:1.The consistency of the coronary angiography and treadmill exercise test in diagnosing coronary heart disease reached to moderate.2. Duke treadmill score risk degree and coronary angiography pathological damage were related.3.Coronary bifurcation lesions enhanced with prolonging duration of menopause, Coronary bifurcation lesions correlated with duration of menopauseADuke score increased risk level as the time increased, Duke Score weakly correlated with duration of menopause.5.Duke score increased risk level as prolonging duration of menopause, Duke Score strongly correlated with duration of menopause.
