early identification of vulnerable plaques by remodeling index prior to rupture and development of acute event is of considerable importance especially by a reliable non-invasive method as CT coronary angiography.

single-center, cross section, observational study included 150 patients with stable angina with normal resting ECG, negative markers, normal systolic function by 2D echocardiography (EF>50%) and without regional wall motion abnormality at rest who were referred to MSCT evaluation of the coronary artery tree.

Inclusion Criteria:

• first attack, low to intermediate risk stable angina
• normal resting ECG,
• negative markers
• normal systolic function by 2D echocardiography (EF>50%)
• without regional wall motion abnormality at rest who were referred to MSCT evaluation of the coronary artery tree.

Exclusion Criteria:

• previous acute coronary syndrome or revascularization, those with renal impairment or dye hypersensitivity, patients with morbid obesity (BMI>40kg/m²), rhythm other than sinus rhythm inability to hold breath for 10sec to acquire the image lesions with heavy calcium score.
