Key Concepts:

Terms in this set (38)

-recipient put on cardiopulmonary bypass...if organ fails, patient dies
-denervation - inability to respond to ANS, no chest pain with ischemia (the nerves from the CNS that supplied connections to your other heart do not supply connections to your transplanted heart.)
-complication: cardiac allograft vasculopathy (like really fast CAD)
-regular biopsies/catheterizations

more info on denervation:
"The heart does not need these nervous system connections to pump effectively. However, the rate at which the transplanted heart pumps at rest and in response to activity (for example, exercise) will be different. Before your operation, your heart would respond to exertion by quickly increasing its rate after the central nervous system told it to. Following your heart transplant, the heart increases its rate only after substances called catecholamines (adrenalin, for example) are released from a gland on the kidney and circulated through the blood to the heart. After exertion, it takes a while for this effect to decrease. Therefore, the transplanted heart increases its rate more gradually with exertion and slows more gradually with rest. To avoid extreme fatigue it is important that you allow time for your heart to increase its rate during exercise and other activity. Your physical therapist and exercise physiologist will provide directions for you to follow.

Loss of central nervous system connections to the heart also means that you will be unable to feel chest pain (angina pectoris) that occurs if coronary artery disease develops in the heart. If you notice chest discomfort, it is probably related to chest wall irritation, tissue healing, or strain from exercise."
