What you need to know about your heart medications

by Carolyn Thomas  ♥  @HeartSisters

One of the most surprising additions to the daily morning routine since my heart attack has been the fistful of pills that I now take every day.

It can be a confusing mix of medications, each for a different purpose, and each with different benefits and side effects.  Here’s just a sampling of some of the more common cardiac meds that doctors prescribe for heart patients.

Anti-platelet Agents

This type of heart medicine can help prevent clots from forming in blood vessels. It accomplishes this by preventing sticky blood platelets from clumping together. Your doctor may prescribe anti-platelet medication if:

• you have had a heart attack
• you have had a coronary stent implanted in a coronary artery
• you have unstable angina
• you have had strokes, including TIAs (transient ischemic attacks)
• you have other types of heart disease
• your doctor has noted plaque buildup in your blood vessels
• you are at high risk for heart attack or stroke

Examples of anti-platelet medicine include aspirin, clopidogrel (Plavix), ticlopidine (Ticlid), ticagrelor (Brilinta – also known as Brilique and Possia in Europe), or prasugrel (Effient or Efient). Since side effects include increased bruising and bleeding, some people may not be able to take anti-platelet meds if they are at risk for bleeding.

Angiotensin-Converting Enzyme (ACE) Inhibitors

This type of heart disease medicine can help because they:

• lower your blood pressure
• make the heart’s work easier
• help the heart work more efficiently

ACE inhibitors work by preventing your body from making angiotensin II, a hormone that makes blood vessels tighten, to help your blood vessels remain relaxed. Blood flows more easily through the vessels, lowering your overall blood pressure. Your heart doesn’t have to work so hard to pump blood through your vessels. About 20% of patients who receive ACE inhibitors develop a dry cough, a side effect so debilitating that you may need to stop the drug; it’s particularly common in women and those of black or Asian ethnicity. Talk to your physician if this side effect occurs.  Capoten (captopril) and Vasotec (enalapril) are examples of ACE inhibitors.

Calcium Channel Blockers (CCBs)

This type of heart disease medicine is also called a calcium antagonist. CCBs can:

• lower your blood pressure
• reduce chest pain (angina)
• help lower your heart rate

CCBs prevent calcium from entering the muscle cells in your heart and blood vessels, keeping blood vessels from tightening and causing the heart to pump with less strength. Your heart rate slows and blood can flow more easily through the vessels, lowering your blood pressure. Cardizem CD (diltiazem) and Norvasc (amlodipine) are examples of CCBs.

Beta Blockers

This type of medicine diminishes the effects of adrenaline and other stress hormones. They  slow heart rate and reduce blood pressure, and are commonly used for treating:

• abnormal heart rhythm
• high blood pressure
• heart failure
• angina (chest pain)
• acute aortic dissection
• hypertrophic obstructive cardiomyopathy
• anxiety
• prevention of migraines.

Beta blockers also have been found to prevent further heart attacks and death after a heart attack. Other uses include the treatment of hyperthyroidism, akathisia (restlessness or inability to sit still), and anxiety. Some beta blockers are also used for reducing pressure in the eye caused by glaucoma.

Examples of beta blockers are Carvedilol, Bisoprolol, Metoprolol, Propanol, or Atenolol.

Cholesterol-Lowering Drugs

Cholesterol-lowering drugs may help those already at high risk for heart disease in these ways:

• lower LDL (bad) cholesterol levels
• raise HDL (good) cholesterol
• lower triglycerides (a fat in your blood)

Cholesterol-lowering drugs work in a variety of ways to improve your heart health. Some change the way the liver processes cholesterol and fat. Others affect the way your body digests nutrients, or prevent cholesterol from flowing through your blood vessels.

Statins (Lipitor, Crestor) lower LDL bad cholesterol levels and may keep fatty cholesterol streaks from forming in your blood vessels.  Tell your doctor immediately if you experience severe muscle pain or other serious side effects of statins.

Vasodilators

Vasodilator heart disease medicine has two effects:

• lowers your blood pressure
• eases chest pain (angina)

Vasodilators relax the muscles in your blood vessel walls. The vessels widen and blood flows through more easily, lowering blood pressure and providing  more blood and oxygen to the heart so it doesn’t have to work so hard to pump. These drugs are often prescribed PRN – meaning take whenever you need them.  They also widen all blood vessels in your body, not just around your heart, including those to the brain, which can cause severe headaches for many patients.  Try taking a Tylenol™ about 20 minutes before taking any vasodilator to avoid getting the famous ‘nitro headache‘.

Examples of vasodilators include nitroglycerin (pills, patch or spray), Isordil (isosorbide dinitrate),  Apresoline (hydralazine) and Loniten (minoxidil).
