Key result
ATI score during primary PCI correlates with final cMRI infarct size in STEMI.
Why the study?
Does the ATI score determined during primary PCI predict final infarct size and microvascular obstruction in patients with STEMI?
Cohort (n=80)
Does the ATI score determined during primary PCI predict final infarct size and microvascular obstruction in patients with STEMI?
The ATI score, calculated during primary PCI using age, pre-stenting IMR, and angiographic thrombus score, correlates with final infarct size assessed by cMRI in STEMI patients.

May refine early STEMI risk stratification during PCI; hypothesis-generating without randomized outcome data.
Maria et al. (2017) conducted a cohort in ST-elevation myocardial infarction (STEMI) (n=80). ATI score was evaluated on Extent of infarct size (IS%) and microvascular obstruction (MVO%) assessed by cMRI. The ATI score calculated prospectively during primary PCI was closely related to final infarct size assessed by cardiac magnetic resonance imaging in patients with STEMI.
