Heart failure & cardiomyopathies
Cardiovascular magnetic resonance to differentiate veteran athlete’s heart with cavity dilatation and mild dilated cardiomyopathy
Authors' conclusion
Septal fibrosis is rare amongst veteran athletes with LV dilation in contrast to mild DCM patients. Native T1, ECV, and RVEDVi can also discriminate between these overlapping phenotypes
Study context
- Population
- Participants with left ventricular ejection fraction (LVEF) > 40% and LVEDVi ≥ 110 mL/m² without ischaemic heart disease or significant cardiac pathology on cardiovascular magnetic resonance (CMR) likely to cause heart failure (HF)
- Participants
- 113 participants
- Exposure
- Veteran athletes with left ventricular (LV) dilatation vs mild dilated cardiomyopathy (DCM) patients
- Athletesn = 64
- Mild DCMn = 49reference
- Outcome
- Distribution of myocardial fibrosis and patterns of tissue characteristics on CMR
