In patients with cardiogenic shock that undergo successful coronary intervention, there are still factors complicating myocardial recovery. There is room for improvement in coronary flow using mechanical circulatory devices, specifically by left ventricular unloading. This idea was further explored in a research study using pigs. Results showed that subjects with acute myocardial infarction who have reduced cardiac contractility and/or high diastolic pressure would benefit from support strategies targeting left ventricular unloading.
