Prognostic value of myocardial scar in ischaemic and non-ischaemic cardiomyopathy using cardiac magnetic resonance imaging.

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.
