Refining the Study of Myocardial Infarction in Sheep

Ischaemic heart diseases continue to be a major global health concern and a leading cause of death. To develop more effective treatments, it is essential for researchers to work with animal models that closely replicate human cardiac physiology. In a notable step forward, Pius et al. present a refined, minimally invasive ovine model of ischaemia–reperfusion–infarction which incorporates implantable defibrillators and addresses many limitations seen in previous approaches, enhancing the safety, reproducibility, and clinical relevance of preclinical cardiac research.
