The use of beta-blockers (CAD 93 % vs DCM 93 %, p = 0.76) and ACE inhibitors/ARBs (CAD 96 % vs DCM 97 %, p = 0.59) did not significantly differ between the groups, but the use of diuretics was higher in patients with DCM (CAD 74 % vs DCM 84 %, p = 0.008). This evidence concerns the gene ACE and familial dilated cardiomyopathy.
