Overview

Retrospective analysis assesses microvascular patterns in STEMI, revealing significant prognostic insights.

Key Points

  • To evaluate the prognostic value of microvascular perfusion patterns derived from CMR imaging in STEMI patients.
  • Retrospective analysis of 584 STEMI patients undergoing contrast-enhanced CMR imaging.
  • Microvascular perfusion patterns categorized based on EGE and LGE imaging results.
  • Follow-up analysis for major adverse cardiovascular events using Cox regression models.
  • 26.8% of patients had No MVO, while 25.2% had Minimally Resolved MVO.
  • Minimally Resolved MVO was associated with a 6-fold higher risk of major adverse cardiovascular events.
  • Patients with Reversible MVO showed elevated event rates despite similar survival compared to No MVO.
