Migraine linked to Heart Disease

One out of five women and one out of fifteen men is found to experience migraines, which is characterized by severe headache and throbbing pain on side of the head. Many people consider migraine as a disorder of the brain, but migraine may be as a result of cardiovascular conditions such as patent foramen ovale (PFO) or a hole in the heart. Why migraine is related to heart problem? Let’s find the cause


A person with PFO has small hole in the septum between the two upper chambers of the heart that remains open after birth. This opening allows blood clot to travel from the right side of the heart to the left, to the brain, and can block the blood flow. Assoc. Prof. Dr.Sombat Muengtaweepongsa, Neurologist of Phyathai 2 Hospital explains that migraine pain that is caused by dilated blood vessel in the brain happens on its own, but for person with PFO, blood clot blocks the blood flow and the blood vessel then dilates or expands.

Is it a normal headache?
Headache can affect anyone and many people are worried that it is a symptom of serious condition. Assoc. Prof. Dr.Sombat Muengtaweepongsa, Neurologist at Phyathai 2 Hospital suggests that “if headache occurs alone, it is normally not a sign of anything serious, however, if a headache develops with other symptoms such as arm or leg weakness on one side of the body, drooping mouth or slurred speech, this can signals serious problems”
Is a closure of a hole in the heart (PFO) help migraines?
Assoc. Prof. Dr.Sombat Muengtaweepongsa, Neurologist of Phyathai 2 Hospital states that among younger people, migraine headache tends to result from brain’s blood vessel dilation. Therefore, we have to investigate whether migraine headaches occur from expansion of blood vessels in the brain or clot forming.
Many studies show that patent foramen ovale (PFO) closure can prevent blood clot to, so blood vessels do not dilate which can relieve migraine pain. In addition, patent foramen ovale (PFO) closure is also shown to reduce the risk of recurrent stroke
Not every case of migraine headache is caused by PFO, and patients with PFO do not suffer only painful headache; hence, it is significant to visit the physician to have the right diagnosis and treatment.
