Cardiac rupture in acute myocardial infarction: a cardiac magnetic resonance study.

ABSTRACT:

Aims

We assessed the feasibility of cardiac magnetic resonance (CMR) and the role of myocardial strain in the diagnostic work-up of patients with acute myocardial infarction (AMI) and a clinical suspicion of cardiac rupture (CR).

Methods and results

Consecutive patients with AMI complicated by CR who underwent CMR were enrolled. Traditional and strain CMR findings were evaluated; new parameters indicating the relative wall stress between AMI and adjacent segments, named wall stress index (WSI) and WSI ratio, were analysed. A group of patients admitted for AMI without CR served as control. 19 patients (63% male, median age 73 years) met the inclusion criteria. Microvascular obstruction (MVO, P = 0.001) and pericardial enhancement (P < 0.001) were strongly associated with CR.
