Heart problems and vascular problems can cause symptoms that are very similiar. Ophthalmologists have to work through tests to be sure something is migraine and not heart, blood vessel or brain problems.
There is a much stonger relationship between family history of migraines and use of birth control pills or estrogens or pregnancy in females than connection with heart problems.
Short summary is that they are two separate problems that can cause similiar symptoms.

By the way migraine problems tend to get better as people get older while heart problems tend to get worse.
