Lung structural remodeling and pulmonary hypertension after myocardial infarction: complete reversal with irbesartan

Abstract

After large myocardial infarct there is important pulmonary structural remodeling in which myofibroblasts (pericytes) proliferation may play an important role. This initially protective mechanism against high filling pressures could eventually contribute to the development of pulmonary hypertension and right ventricular hypertrophy. Future studies are needed to determine if angiotensin-II directly modulates pulmonary remodeling after myocardial infarct.
