VIP and myocardial infarction: We found that the levels of PS40:6, PS38:3, PS40:7, PS38:4, PS38:6, PS40:5, PS36:2, PS38:5, and PS38:2 were significantly decreased in cardiac tissues post-MI, and VIP score analysis showed that PS40:6 is the greatest metabolite contributing to MI injury and remodeling.
