Abstract- Thus, this study aims to explore the long-term effects of quantitatively evaluated IAC on stroke, other cardiovascular events and related mortality in patients, to establish an effective screen tool for stratifying high risk patients and facilitate effective secondary prevention. The results of this study demonstrate that quantitative evaluated IAC score is strongly predictive of non-cardioembolic stroke, myocardial infarction and cardiovascular death in our hospital population in this prospective analysis. Further studies are warranted to evaluate the clinical implications of measuring IAC in screening subjects at high risk of vascular events.
