What Is the Connection Between Headaches and Mitral Valve Prolapse?


Quick Answer

A mitral valve prolapse can induce headaches by increasing tension in the blood vessels of the brain, according to MedicineNet. In rare cases, a mitral valve prolapse causes headaches through increased blot clotting.

Full Answer

A mitral valve prolapse is a heart abnormality that causes the heart’s mitral valve to function inadequately, informs MedicineNet. In this condition, blood from the atrium of the heart flows back into the ventricles of the heart after a contraction, making the valve leaky. This causes blood to pump less efficiently through the body.

A mitral valve prolapse may involve an imbalance in the body's autonomic nervous system, notes MedicineNet. This system is responsible for regulating a person’s normal heart rate and controlling the constriction of the blood vessels of the brain. An imbalance in the autonomic nervous system can cause an abnormal control of brain tension.

Additionally, a mitral valve prolapse may encourage the formation of blood clots, adds the National Heart, Lung and Blood Institute. Blood clots form when the blood pools in the atria of the heart and when it is not pumped out fast enough. Clots can reduce blood flow to the brain or travel from the heart to the brain and cause a stroke.
