Study Says Epinephrine May Help Fight Heart Attack

Study Says Epinephrine May Help Fight Heart Attack


Your heart is beating very fast, you are sweating. . You may be under stress due to fear, anger or nervousness. These are our body's normal reaction to stressful situations and may be attributed to the hormone epinephrine or adrenaline. The hormone epinephrine or adrenaline normally maintains the heart's pumping strength and makes the heart beat faster during critical situations. This same effect of adrenaline to the body may help fight heart failure.

This neurotransmitter is related to Calm PRT, Kavinace, AdreCor, Balance D, and ExcitaPlus.


Scientists from the University of Rochester Medical Centre (URMC) found that drugs containing adrenaline or epinephrine may help restore a failing heart because of the naturally occurring physiological response of the body to the release of these hormones. When epinephrine stimulates beta receptors found in the heart and lungs, air passages relaxes and opens, thus making breathing easier.

In a nutshell, epinephrine or adrenaline hormones are responsible for the fight or flight response of the body to certain situations that require the body to run or face the situation. They are released by the adrenal glands in response to stressful situations giving the body the added boost or extra exertion it needs to respond to threatening situations.

Administering these hormones into a patient with a failing heart will aid in reviving the pumping motion of the heart. While increased adrenalin initially restores the heart's vivacity, over time heart muscle cells become less and less responsive to high levels of adrenalin. This is mainly due to the chronic desensitizing of the receptors. Desensitizing means that the heart no longer responds as accurately as it should to adrenaline thus making the heart grow weak and stops pumping as vigorously as it should. The said event is mainly caused by the heightened levels of an enzyme known as GRK2 when it relates with G-proteins.
