Key result
Myocardial scar size assessed by CMR was a strong predictor of clinical cardiac events over at least 6 months in 154 patients with ischaemic and non-ischaemic cardiomyopathy.
Why the study?
The study was conducted to evaluate the prognostic value of myocardial scar using CMR imaging in patients with ischaemic cardiomyopathy and non-ischaemic cardiomyopathy.
Does myocardial scar size assessed by CMR predict clinical cardiac events in patients with ischaemic and non-ischaemic cardiomyopathy?

Does myocardial scar size assessed by CMR predict clinical cardiac events in patients with ischaemic and non-ischaemic cardiomyopathy?
p-value: p== 0.128
Myocardial scar size assessed by CMR is a strong predictor of clinical outcomes in patients with ischaemic and non-ischaemic cardiomyopathy, potentially outperforming LVEF.
AIM: The aim of this research was to evaluate the prognostic value of myocardial scar using cardiac magnetic resonance (CMR) imaging in patients with ischaemic cardiomyopathy (ICM) and non-ischaemic cardiomyopathy (NICM). METHODS: One hundred and fifty-four patients with either ICM or NICM underwent CMR with late gadolinium enhancement sequences for assessment of left ventricular ejection fraction (LVEF), and detection and quantification of any myocardial scar using three methods: manual, number of segments involved, and percentage of scarred myocardium. Patients were followed up for at least six months for clinical cardiac events. RESULTS: = 0.128). CONCLUSIONS: Myocardial scar size was a strong predictor of clinical outcome in both the ICM and NICM patients. LVEF was less reliable in predicting morbidity in cardiomyopathy patients.

Laymouna et al. (2023) conducted a cohort in Ischaemic and non-ischaemic cardiomyopathy (n=154). Myocardial scar size assessed by CMR was evaluated on Clinical cardiac events (p== 0.128). Myocardial scar size assessed by CMR was a strong predictor of clinical cardiac events over at least 6 months in 154 patients with ischaemic and non-ischaemic cardiomyopathy.
