Positive remodeling index by MSCT coronary angiography: A prognostic factor for early detection of plaque rupture and vulnerability

Conclusion Previous studies had shown that most acute coronary syndromes were initiated by sudden changes of mildly stenotic lesions, commonly found in positively remodeled vessels. Promising comparative results between MSCT and IVUS allowed consideration of MDCT as a useful tool in the noninvasive detection of potentially threatening coronary lesions. In our study, RI⩾1.5 showed a strong correlation between the lipid plaque area, multiplicity of the plaques, and cross sectional area which were prognostic factors for plaque rupture and vulnerability, and thus, early detection of coronary artery disease. Modulation and prevention of positive remodeling by statin could promote to start medical treatment especially in cases where RI exceeds 1.5 and their follow up non-invasively by MDCT to detect reversal of remodeling and response of treatment.
