Research On Value Of 320-slice Dynamic Volume Mdcta In The Correlation Between Gradation Of Coronary Stenosis And Risk Factors Of Coronary Artery Heart Disease

Objective:To study the value of 320-slice spiral CT angiography (320-MDCTA) in the correlation between gradation of coronary stenosis and risk factors of coronary artery heart disease.Methods:59 inpatients that were clinically diagnosed or clinically suspected of coronary artery heart disease and then diagnosed via medical examinations during Octorber.2009 and March.2010 were seleceted retrospectively, and the gradation of coronary stenosis was scaled quantitatively by Gensini. All inpatients were divided into four groups by Gensini.we analyzed the difference of age sex blood-pressure blood-lipids smoking diabetes and amount of risk factors among four groups and the significant graduation of risk factors in the coronary artery heart disease by single and multivariant factor analysis method. Results:The single factor analysis show that the percents of single risk factors and risk factors'amounts raise up gradually by Gensini scales increase except for age. multivariant factor analysis show that hypertension is the most significant correlate factor independently of coronary stenosis.The other risk factors are as follows: hyperlipemia smoking diabetes and male in turn.Conclusion:The gradation of coronary stenosis correlates with risk factors of coronary artery heart disease and theirs' amount. Hypertension is the most significant correlate factor independently of coronary artery heart disease's diagnosis by 320-slice dynamic volume MDCTA.320-slice dynamic volume MDCT can provide a basis for coronary artery heart disease and its criticality.
