Pharm Ch 26

Drugs for Heart Failure

TermDefinition
afterload the degree of pressure in the aorta that must be overcome for blood to be ejected from the left ventricle
cardiac glycosides drug class that include digitalis
cardiac output amount of blood pumped by a ventricle in 1 minute
cardiac remodeling change in the size, shape, and structure of the myocardial cells (myocytes) that occurs over time in heart failure
contractility the strength with which the myocardial fibers contract
digitalization procedure in which the dose of cardiac glycoside is gradually increased until tissues become saturated with the drug, and the symptoms of heart failure diminish
Frank-Starling law the greater the degree of stretch on the myocardial fibers, the greater will be the force by which they contract
heart failure (HF) disease in which the heart muscle cannot contract with sufficient force to meet the body's metabolic needs
inotropic effect change in the strength or contractility of the heart
peripheral edema swelling of extremities
phosphodiesterase enzyme in muscle cells that cleaves phosphodiester bonds; its inhibition increases myocardial contractility
preload degree of stretch of the cardiac muscle fibers just before they contract
adrenergic blockers decrease cardiac workload by slowing the heart rate and decreasing blood pressure
vasodilators decrease cardiac workload by dilating vessels and reducing preload
phosphodiesterase inhibitors increase cardiac output by increasing the force of myocardial contraction
ACE inhibitors and angiotensin receptor blockers increase cardiac output by lowering blood pressure and decreasing blood volume
cardiac glycosides increase cardiac output by increasing the force of myocardial contraction
diuretics increase cardiac output by reducing fluid volume and decreasing blood pressure

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
