Ligature permanente de l'artère interventriculaire antérieure coronaire chez la souris: Un modèle de post-infarctus du myocarde et de remodelage de l'insuffisance cardiaque

Overview

This article presents a model of permanent ligation of the left anterior descending coronary artery in mice to study cardiac remodeling and heart failure following myocardial infarction. The technique includes invasive hemodynamic measurements to evaluate cardiac function.
