Common post-CABG medications, including angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACE-I/ARBs), beta-blockers, antiarrhythmic drugs (AAD), calcium channel blockers (CCB), and statins, were not significant predictors of SCD (p = 0.380, 0.450, 0.428, 0.337, and 0.185, respectively). This evidence concerns the gene ACE and Schnyder corneal dystrophy.
