SERPINA4 and familial dilated cardiomyopathy: Components of the blood coagulation cascade were amongst the most significant regulated proteins in ICM, but not DCM, as kallistatin (SERPINA4) (FC = 2.6, P = 1.6 × 10−4), heparin cofactor II (SERPIND1) (FC = 2.3, P = 3.6 × 10−4) and kininogen 1 (FC = 1.8, P = 2.4 × 10−3) were all differential when comparing ICM and donor myocardium.
