perfusion was not restored; reperfused infarcts can have other hallmarks, such as contraction band necrosis. These tables gives an overview of the histopathology seen in myocardial infarction by time after obstruction. By individual parameters Some authors summarize the vascular and early fibrotic changes as 'granulation tissue', which is maximal at 2–3 weeks Differential diagnoses for myocardial fibrosis: Interstitial fibrosis, which is nonspecific, having been described in congestive heart failure, hypertension, and normal aging. Subepicardial fibrosis, which is associated with non-infarction diagnoses such as myocarditis and non-ischemic cardiomyopathy.
