Heart failure & cardiomyopathies
Predictive Value for Mortality of Left Ventricular Wall Thickness in Dilated Cardiomyopathy
Authors' conclusion
PWT measured by CMR is an independent predictor of all-cause mortality in DCM patients. However, there was no significant correlation between septum wall thickness and mortality.
Study context
- Population
- Dilated cardiomyopathy (DCM) patients who underwent cardiac magnetic resonance (CMR) and completed regular follow-up
- Participants
- 161 patients
- Comparison
- Death vs non-death
- Deathn = 41
- Outcome
- All-cause mortality
- Follow-up
- Median 47 months (IQR 32-57 months)
