“…Huang et al 4 correlated apoptotic markers with left ventricular wall stress in a chronic ovine microembolization-induced heart failure model. A porcine model of microembolization-induced heart failure was used by Buus et al 5 to demonstrate the preservation of contractile function of the smooth muscle cells and endothelial production of nitric oxide in small coronary arteries. These studies exemplify the principle that although a multitude of large animal models of heart failure exist, it is crucial to select the model most appropriate to the clinical issue being investigated.…”
