Early cardiac magnetic resonance imaging in troponin-positive acute chest pain and non-obstructed coronary arteries

Abstract: ObjectiveWe assessed the diagnostic and prognostic implications of early cardiac magnetic resonance (CMR), CMR-based deformation imaging and conventional risk factors in patients with troponin-positive acute chest pain and non-obstructed coronary arteries.MethodsIn total, 255 patients presenting between 2009 and 2019 with troponin-positive acute chest pain and non-obstructed coronary arteries who underwent CMR in ≤7 days were followed for a clinical endpoint of all-cause mortality. Cine movies, T2-weighted and… Show more

“…More recent studies corroborate these findings, emphasizing that MI is not the most frequent cause of this clinical presentation. These data also demonstrate a key role for CMR in the diagnostic pathway for patients with unexplained acute myocardial injury following culprit-free coronary angiography ( 5 8 ).…”

“…Based on published data, 25% of the modeled population had a true MI ( Table 1 ) ( 2 , 5 ) and annual rates of a major bleed on DAPT, aspirin or no therapy were estimated as 2, 0.6, and 0.46%, respectively ( 2 , 14 16 ). The assumed mortality rate in the first year after a diagnosis of unexplained acute myocardial injury and normal coronary angiography was 3.4 and 2.8% for subsequent years ( 3 , 4 ).…”

“…Following multivariate cox regression analysis including clinical and CMR parameters, ST-segment elevation on presenting ECG and cardiomyopathy on CMR imaging were the only two significant predictors of mortality, underpinning the added diagnostic and prognostic utility of performing CMR early after presentation in MINOCA patients. 7 , 8 …”
