Intramyocardial hemorrhage (IMH), coupled with microvascular obstruction (MVO), is
an independent predictor of adverse remodelling following ST-segment elevation myocardial
infarction (STEMI)
1
. In the acute phase (<3 days) of MI, MVO, and IMH concurrently occur in 40% to 60%
of patients presenting with STEMI and typically resolve by 1 to 3 months post-MI.

However, recent studies have offered evidence that IMH, although not MVO, can persist
even up to the chronic phase (>2 months) and is associated with greater inflammation,
adverse remodelling and poorer outcomes.

In this study, we exploited the comprehensive nature of cardiovascular magnetic resonance
(CMR) imaging to highlight a unique STEMI case exhibiting the chronic presentation
of both IMH and MVO, along with heightened inflammation.To read this article in full you will need to make a payment
