My dad is an alcoholic, could his addiction have contributed to his coronary artery disease?

Yes. Drug and alcohol addiction have serious negative health consequences on all of the body’s organs including the heart and brain. There is a direct connection between drug abuse and irregular heartbeat, collapsed veins, bacterial infections, cardiovascular distress, heart attack, and stroke.

Not really. High salt intake will have an impact on fluid retention and blood pressure and as such play a role in the dynamics of blood flow in your arteries as well as trigger a few, expected, hormonal responses to deal with the salt load and thus possibly contribute to the development of plaques, but there is no direct imapct of salt on the plaque in the arteries.
