Heart Medications: A Guide for Patients and Caregivers

After a heart attack, heart failure diagnosis, or hypertension diagnosis, patients often leave the hospital with a bag full of new prescriptions. It can be overwhelming. Here's a plain-language guide to the most common heart medications and what they do.

Statins: Lowering Cholesterol

Atorvastatin (Lipitor), rosuvastatin (Crestor), and simvastatin reduce LDL ("bad") cholesterol by blocking an enzyme in the liver. They're among the most prescribed medications in the US and have strong evidence for reducing heart attack and stroke risk.

Common concern: muscle aches. If you develop unexplained muscle pain or weakness, tell your doctor — this can occasionally be a sign of a more serious side effect called myopathy.

Beta Blockers: Slowing the Heart

Metoprolol (Lopressor, Toprol XL) and carvedilol (Coreg) reduce heart rate and blood pressure by blocking adrenaline. They're used for hypertension, heart failure, angina, and after heart attacks.

Don't stop beta blockers suddenly — this can cause rebound effects including rapid heart rate and increased blood pressure. Always taper under medical supervision.

ACE Inhibitors and ARBs: Protecting the Heart and Kidneys

Lisinopril (an ACE inhibitor) and losartan, valsartan (ARBs) relax blood vessels and reduce the workload on the heart. They're also protective for the kidneys, especially in diabetic patients.

ACE inhibitors can cause a persistent dry cough in some people. If this bothers you, your doctor may switch you to an ARB instead.

Blood Thinners: Preventing Clots

Warfarin (Coumadin) and apixaban (Eliquis) prevent blood clots. Warfarin requires regular blood tests (INR monitoring) to keep levels in the right range. Apixaban and other newer anticoagulants (DOACs) don't require monitoring but are more expensive.

If you're on a blood thinner, be careful with cuts, avoid contact sports, and tell every healthcare provider you see — including dentists.

Diuretics: Reducing Fluid Buildup

Furosemide (Lasix) and spironolactone help the kidneys remove excess fluid, reducing swelling and easing the heart's workload. Common in heart failure treatment.

Never Miss a Dose

Heart medications work best when taken consistently. Use MedTrack to check pharmacy stock before you run low — especially for medications like warfarin and beta blockers where missing doses can have immediate consequences.
