Term
| How do adrenergic drugs effect people with CHF? |
|
Definition
| The left ventricle is weak in people with CHF therefore their CO is very low. Increasing the BP decreases the amount of oxygenated blood to the tissues which increases the demand for oxygenated blood. Adrenergic drugs increase the contractility of the heart which overworks the left ventricle. The blood is not getting pumped around fast enough so the demand continues to increase until heart fails. |
