Linking factor XIII activity to all-cause mortality after myocardial infarction: the overlooked role of serum albumin

Although lower FXIII activity is associated with higher mortality post-MI, this effect is largely mediated by albumin levels. Albumin appears to be a central determinant of both FXIII activity and prognosis, highlighting its potential role as a key marker in risk stratification. Further studies are warranted to explore therapeutic implications of hypoalbuminemia in MI.
