Why the study?
The prognostic value of CMR-measured LV global function index for predicting mortality and ICD therapies in secondary prevention ICD patients needed evaluation to identify high-risk individuals.
Does a lower LVGFI measured by CMR predict mortality and rehospitalization in patients with an ICD for secondary prevention?
Does a lower LVGFI measured by CMR predict mortality and rehospitalization in patients with an ICD for secondary prevention?
In patients with an ICD for secondary prevention, a reduced LVGFI measured by CMR is an independent predictor of mortality and rehospitalization, potentially outperforming traditional LVEF.
No takes yet. Share an insight, caveat, or question.
LVGFI by CMR may refine risk stratification in secondary prevention ICD patients; hypothesis-generating and requires prospective validation.
Schober et al. (2021) studied this question.
