Heart and blood vessel problems

4-FA affects blood pressure and heart rate. In general, blood pressure and heart rate increase. We do not know exactly how the influence of 4-FA on the blood pressure and heart rate works.

Increased blood pressure and heart rate increase the risk of a cerebral infarction. A blood vessel in the brain can break. Or a blood clot can break loose and block the vessel in a smaller part of the blood vessel. If oxygen can no longer reach the brain cells, the brain cells may die.
