Correlation Study of Coronary CT Imaging Quantitative Parameters with Illness Severity of Coronary Heart Disease Patients
Objective To study the correlation of coronary CT imaging quantitative parameters with illness severity of coronary heart disease patients.Methods 90 coronary heart disease patients treated from September 2018 to September 2019 in our hospital were set as observation group.Over the same time period,90 healthy volunteers were set as control group.Coronary CT angiography was performed.Correlation of CT imaging quantitative parameters with illness severity was analyzed.Results Number of plaques,non-calcified plaque area,calcified plaque area,overall plaque area,non-calcified plaque burden,calcified plaque burden,overall plaque burden and vascular stenosis degree in the observation group were larger than those of control group,with statistically significant difference(P＜0.05);vascular volume between groups was not significantly different(P＞0.05);LVMI(left ventricular mass index),LVESV(left ventricular end-systolic volume),LVEDV(left ventricular end-diastolic volume)and mean wall stress values in the observation group were larger than those of control group;LVEF(left ventricular ejection fraction)values were smaller than those of control group(P＜0.05);number of plaques,non-calcified plaque area,calcified plaque area,overall plaque area,non-calcified plaque burden,calcified plaque burden,overall plaque burden and vascular stenosis degree were negatively correlated with LVEF,but positively correlated with LVMI,LVESV,LVEDV and mean wall stress;reconstruction indicators were positively correlated with LVEF,but positively correlated with LVMI,LVESV,LVEDV and mean wall stress(P＜0.05);vascular volume was not related to cardiac function(P＞0.05).Conclusion The coronary CT imaging quantitative parameters have close correlation with illness severity,which may be taken for prediction of clinical treatment prognosis.
