Several of the proteins impacted by myectomy (POSTN, MMP12, CDON, NAMPT, HAMP, LTA4H) were previously reported to be altered in cardiovascular disease, cardiomyopathy, or vascular disease with effects mediated through inflammatory mechanisms [5,6,7,8,9,10,11,12,13]. Here, POSTN is linked to cardiomyopathy.
