摘　　要：Objectives:?The aim of this study is to evaluate the relationship between severity of CAD by coronary mutlislice computed tomography scan and the degree of diastolic function Methods:?The study consisted of 80 patients who underwent both coronary CTA and TTE within 1 year with no identifiable intervening cardiovascular event in National?Heart?Institute and Menoufia?University?Hospitals. All patients were subjected to detailed medical history, physical examination, full electrocardiography study including tissue Doppler imaging on mitral annulus, MSCT coronary angiography and different laboratory investigation as CBC, creatinine, lipid profile. Results:?From 80 patients who have done both echocardiography examination and MSCT coronary angiography, the CT scan results were 38 patients with non-obstructive coronary artery disease and 42 patients with obstructive CAD, higher number of patients with diastolic dysfunction with higher values of E/E’, medial e’, lateral e’, LAVI (left atrial volume index) and TRV (tricuspid regurge velocity) were found in the group with obstructive coronary artery disease.?Conclusion:?Our study showed that diastolic dysfunction is more prevalent in patients with obstructive coronary artery disease with higher grade of diastolic dysfunction.Objectives:?The aim of this study is to evaluate the relationship between severity of CAD by coronary mutlislice computed tomography scan and the degree of diastolic function Methods:?The study consisted of 80 patients who underwent both coronary CTA and TTE within 1 year with no identifiable intervening cardiovascular event in National?Heart?Institute and Menoufia?University?Hospitals.
