Understanding Your Medications
Learn about common heart medications, how they work, potential side effects, and tips for managing your medication regimen.
Common Heart Medications
Understanding your medications helps you take them correctly and recognize potential problems:
Blood Thinners (Anticoagulants/Antiplatelets)
- **Aspirin**: Prevents blood clots by stopping platelets from sticking together - **Clopidogrel (Plavix)**: Often used with aspirin after stent placement - **Warfarin (Coumadin)**: Prevents blood clots; requires regular blood tests - **Direct Oral Anticoagulants (DOACs)**: Includes Eliquis, Xarelto, Pradaxa; used for AFib and blood clots
Blood Pressure Medications
- **ACE Inhibitors** (e.g., lisinopril): Relax blood vessels, lower blood pressure - **ARBs** (e.g., losartan): Similar to ACE inhibitors - **Beta-Blockers** (e.g., metoprolol): Slow heart rate, lower blood pressure - **Calcium Channel Blockers** (e.g., amlodipine): Relax blood vessels - **Diuretics** (e.g., furosemide): Remove excess fluid
Cholesterol Medications
- **Statins** (e.g., atorvastatin, rosuvastatin): Lower LDL cholesterol, reduce heart disease risk - **Ezetimibe (Zetia)**: Reduces cholesterol absorption - **PCSK9 Inhibitors**: Powerful LDL-lowering injections
Heart Rhythm Medications
- **Antiarrhythmics** (e.g., amiodarone, flecainide): Control abnormal heart rhythms - **Digoxin**: Helps control heart rate in AFib
Heart Failure Medications
- **ACE Inhibitors/ARBs/ARNI**: Improve heart function - **Beta-Blockers**: Reduce heart workload - **Diuretics**: Remove excess fluid - **Aldosterone Antagonists**: Improve outcomes in heart failure
