If he has a heart murmur and the vet thinks it warrants Enalapril, then he needs to be on that drug. With a murmur and possible enlargement, that drug is very likely necessary for his health. Vets don't hand out heart meds for no reason.
Vitamins cannot replace drugs in most cases. There is enough danger just because he has heart disease. Not treating it how it needs to be puts him in even more danger.
