Key result
Early MRI established a diagnosis in 97% of patients with acute coronary syndrome and unobstructed coronary arteries, identifying Takotsubo syndrome in 33% who had a 16.9% MACE rate.
Why the study?
The underlying diagnosis in patients presenting with acute coronary syndrome and unobstructed coronary arteries remains a diagnostic challenge.
Does MRI help establish the underlying diagnosis and predict clinical events in patients with acute coronary syndrome and unobstructed coronary arteries?
Observational (n=213)
No
Does MRI help establish the underlying diagnosis and predict clinical events in patients with acute coronary syndrome and unobstructed coronary arteries?
Absolute Event Rate: 16.9% vs 3.6%
Early MRI in patients with ACS and unobstructed coronary arteries effectively establishes the underlying diagnosis, revealing a high prevalence of Takotsubo syndrome which is associated with poorer long-term outcomes.
No takes yet. Share an insight, caveat, or question.
Supports early MRI for etiological diagnosis in ACS with unobstructed arteries; leaves open impact on management or outcomes.
Abanador-Kamper et al. (2018) conducted an observational in Acute coronary syndrome with unobstructed coronary arteries (n=213). Cardiovascular magnetic resonance imaging (MRI) was evaluated on Major adverse cardiac events (MACE). Early MRI established a diagnosis in 97% of patients with acute coronary syndrome and unobstructed coronary arteries, identifying Takotsubo syndrome in 33% who had a 16.9% MACE rate.
