Key result
CMR abnormalities affect 59% of MINOCA patients and correlate with higher Troponin T levels.
Why the study?
The characteristics of MINOCA patients with and without CMR abnormalities needed to be determined.
What are the clinical characteristics and outcomes of MINOCA patients with versus without CMR abnormalities?
Cohort (n=34)
No
What are the clinical characteristics and outcomes of MINOCA patients with versus without CMR abnormalities?
Absolute Event Rate: 5% vs 7.1%
CMR identifies ischemic changes or edema in over half of MINOCA patients, who present with higher troponin levels despite similar ECG and echocardiographic findings.
No takes yet. Share an insight, caveat, or question.
CMR abnormalities may indicate greater injury in MINOCA; hypothesis-generating and should not yet change practice.
Tayal et al. (2020) conducted a cohort in Myocardial infarction with non-obstructive coronary arteries (MINOCA) (n=34). Cardiac magnetic resonance (CMR) abnormalities (LGE or oedema) vs. Absence of CMR abnormalities was evaluated on Major adverse cardiovascular events (MACE) including non-fatal MI, all-cause mortality, ventricular arrythmias or heart failure hospitalisation. Cardiac magnetic resonance (CMR) abnormalities were present in 59% of patients with MINOCA and were associated with significantly higher Troponin T levels compared to those without CMR abnormalities.
