Evidence continues to mount about a link between migraine with aura and cardiovascular disease. Two new studies reported in BMJ (British Medical Journal) found an increased risk for earlier death from any cause, including heart disease and stroke. Researchers were quick to note, however, that the increased risk is still low and should not be cause for anxiety.

The calcium channel blockers are a group of medications that have been used for treating a variety of cardiovascular disorders such as high blood pressure. These medications alter the movement of calcium ions into muscle cells of blood vessels. This effect can sometimes prevent blood vessel changes, which are involved in migraine and cluster headache.
