Heart Medications (Cont.)

 

Angiotensin II Receptor Blockers (ARBs)
Angiotensin II receptor blockers (ARBs) are newer blood pressure medicines that block a chemical (angiotensin II) that normally causes blood vessels to narrow. By blocking the effects of angiotensin II, ARBs cause blood vessels to relax, which can lower blood pressure. ARBs may also be used to treat congestive heart failure and kidney damage from diabetes (diabetic nephropathy), or improve survival following a heart attack.
 
Some examples of ARBs include:
 

 

Anticoagulants
Anticoagulants decrease the ability of the blood to clot and, therefore, help to prevent clots from forming in your arteries and blocking blood flow. These heart medications are sometimes called "blood thinners," though they do not actually thin the blood. Anticoagulants will not dissolve clots that have already formed, but they may prevent the clots from becoming larger and causing more serious problems.
 
An example of an anticoagulant used as a treatment for heart disease is warfarin (Coumadin®, Jantoven®).
 
Antiplatelets
Antiplatelets are medications that stop blood particles called platelets from clumping together to form harmful clots. These heart medications may be given to people who have had a heart attack, have angina, or who experience chest pain after an angioplasty procedure. Aspirin is one type of antiplatelet medicine. Other antiplatelets include:
 
  • Clopidogrel (Plavix®)
  • Dipyridamole (Aggrenox®, Persantine®, and others)
  • Ticlopidine (Ticlid®).
     
Beta Blockers
Beta blockers slow the heart rate and allow it to beat with less force. They are used to treat high blood pressure and some arrhythmias (abnormal heart rhythms), and to prevent a repeat heart attack. These heart medications can also delay or prevent the development of angina.
 
Examples of beta blockers used in heart disease treatment include:
