Heart failure is a condition in which the heart’s muscle gets injured from something like a heart attack or high blood pressure and gradually loses its ability to pump enough blood to supply the body’s needs. When researchers blocked the receptor using a drug, the bursts of nerve activity stopped and breathing and heart function improved.They also found that the P2X3 receptor played a role in producing these bursts of nerve activity.Researchers from the University of Auckland in New Zealand report that in male rats with heart failure, the carotid body (an oxygen-sensing organ) produced sudden bursts of nerve activity that were linked to breathing problems.Share on Pinterest Researchers say nerve activity bursts may linked to heart failure.
