Medial hypertrophy in patients with pulmonary embolism: anatomopathological study.

Objective: To compare the arterial response of cases of acute and chronic embolism, seeking to associate ischemic pulmonary remodeling with progression to chronicity.

Methods: Retrospective analysis of 61 necropsies of patients who died in the Instituto do Coração (31 cases of pulmonary embolism and 30 cases of acute myocardial infarction). Slides of pulmonary tissue were obtained from all cases and analyzed qualitative and quantitatively (medial thickness measurement).
