“Nonischemic Fibrosis on Cardiovascular Magnetic Resonance Does Not Predict Adverse Outcomes in Structurally Normal Hearts, but Elevated Diffuse Microscopic Fibrosis Increases All-Cause Mortality”

https://pubmed.ncbi.nlm.nih.gov/38117807

In patients with structurally normal hearts, the presence of nonischemic fibrosis on cardiovascular magnetic resonance does not predict adverse outcomes, but elevated diffuse microscopic fibrosis, measured by extracellular volume fraction, is associated with increased all-cause mortality.
