• However, all these studies focused on features describing mainly the global coronary tree, while the association between calcium score and the severity of coronary lesions in acute coronary syndrome (ACS) has not been described yet.
AIM OF THE STUDY
Correlation between the accumulation of calcium within the vessel wall of a coronary artery and the severity of coronary artery stenoses in patients who developed an acute coronary event.
