Résumé
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 (CTA), so we aim to evaluate coronary artery remodeling index in patients with low- to intermediate-risk stable angina by CTA. This single-center, cross-sectional, 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; the mean age was 56.8 ± 6.4 years, 83.3% had one-vessel disease, and 16.7% had two-vessel diseases. The mean remodeling index (RI) was 1.04 ± 0.28, 38% had significant positive remodeling, LAD was the most affected vessel (55.3), and proximal lesions were predominant in 48.5%; there was a statistically significant positive correlation between RI and cholesterol, triglyceride, LDL, duration of DM, HBA1c, and plaque burden (P < 0.001) and a statistically significant negative correlation with HDL (P < 0.001). Predictors of higher RI were positive family history, diabetes mellitus, low HDL, HBA1c, and plaque burden% (P < 0.001). Patients with remodeling index > 1.1 were diabetic, hypertensive, smoker, with longer duration of diabetes mellitus, higher HBA1c, cholesterol, triglyceride, LDL, plaque burden, wall lumen ratio, stenosis area, and lower HDL. CTA was able to detect the presence and extent of early, non-obstructive but significant coronary artery-positive remodeling in patients with low- to intermediate-risk stable angina patients.

RESULTS
This single-center, cross-sectional, 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; the mean age was 56.8 ± 6.4 years, 83.3% had one-vessel disease, and 16.7% had two-vessel diseases. The mean remodeling index (RI) was 1.04 ± 0.28, 38% had significant positive remodeling, LAD was the most affected vessel (55.3), and proximal lesions were predominant in 48.5%; there was a statistically significant positive correlation between RI and cholesterol, triglyceride, LDL, duration of DM, HBA1c, and plaque burden (P < 0.001) and a statistically significant negative correlation with HDL (P < 0.001). Predictors of higher RI were positive family history, diabetes mellitus, low HDL, HBA1c, and plaque burden% (P < 0.001). Patients with remodeling index > 1.1 were diabetic, hypertensive, smoker, with longer duration of diabetes mellitus, higher HBA1c, cholesterol, triglyceride, LDL, plaque burden, wall lumen ratio, stenosis area, and lower HDL.
CONCLUSION
CONCLUSIONS
CTA was able to detect the presence and extent of early, non-obstructive but significant coronary artery-positive remodeling in patients with low- to intermediate-risk stable angina patients.
