Identifying predictors of this fibrosis is crucial for risk stratification.

Late gadolinium enhancement (LGE) was used to identify LV fibrosis, categorizing patients into two groups: those without fibrosis (Group I,\n                      <jats:italic>n<\/jats:italic>\n                      = 50) and those with fibrosis (Group II,\n                      <jats:italic>n<\/jats:italic>\n                      = 10).
