Heart Medicines: A Complete Guide for Cardiac Patients
Heart disease is the leading cause of death in India, responsible for approximately 28% of all deaths. For the millions of Indians managing coronary artery disease, heart failure, arrhythmias, or high cholesterol, understanding your cardiac medicines is essential for safe and effective treatment.
Statins — Cholesterol-Lowering Medicines
Statins are among the most prescribed medicines in the world, with strong evidence for reducing heart attack and stroke risk.
Common Statins in India
- Atorvastatin (Atorva, Lipitor): Most commonly prescribed; highly potent
- Rosuvastatin (Rozavel, Crestor): Potent; good option for those with side effects on atorvastatin
- Simvastatin: Older, moderately potent statin
Taking Statins Safely
- Take at night for maximum cholesterol-lowering effect (cholesterol synthesis peaks at night)
- Avoid large quantities of grapefruit juice (increases statin blood levels)
- Report muscle pain, weakness, or dark urine immediately (may indicate myopathy)
- Liver function tests periodically (liver side effects are rare but possible)
Antiplatelet Agents — Blood Thinners That Prevent Clot Formation
Aspirin (Low Dose)
75mg–150mg daily aspirin is prescribed after heart attack, stent placement, stroke prevention in high-risk patients, and peripheral artery disease.
- Take with or after food to reduce stomach irritation
- Never stop suddenly after a heart attack or stent without doctor’s advice (risk of stent thrombosis)
- Tell your dentist/surgeon before any procedure
Clopidogrel (Plavix, Clopilet)
Often combined with aspirin (dual antiplatelet therapy, DAPT) after coronary stent placement. Usually continued for 6–12 months post-stenting; sometimes longer.
Ticagrelor (Brilinta)
More potent antiplatelet used in acute coronary syndromes. Take twice daily. Shortness of breath is a common (usually mild) side effect.
Anticoagulants — Stronger Blood Thinners
Warfarin (Warf, Coumadin)
Used for atrial fibrillation, mechanical heart valves, DVT, and pulmonary embolism. Requires regular INR (International Normalised Ratio) blood test monitoring.
- Target INR: 2.0–3.0 for most indications; 2.5–3.5 for mechanical mitral valves
- Highly sensitive to vitamin K intake — maintain consistent green vegetable consumption
- Many drug interactions — always inform all doctors you are on warfarin
Direct Oral Anticoagulants (DOACs)
Examples: Rivaroxaban (Xarelto), Apixaban (Eliquis), Dabigatran (Pradaxa)
Newer alternatives to warfarin for atrial fibrillation and DVT/PE. Do not require regular blood monitoring but are more expensive. Must be taken consistently and not missed.
Nitrates — Medicines for Angina (Chest Pain)
- Sublingual GTN (Sorbitrate, Nitrostat): For acute angina attacks — dissolve under tongue; repeat after 5 minutes if needed; seek emergency help if three doses don’t relieve pain
- Long-acting nitrates (Isosorbide mononitrate — Imdur, Monotrate): For prevention; always have a nitrate-free period (8 hours) to prevent tolerance
Critical warning: Never take nitrates if you have taken sildenafil (Viagra), tadalafil, or similar PDE5 inhibitors within 24 hours — can cause fatal blood pressure drop.
Medicines for Heart Failure
- ACE Inhibitors/ARBs: Reduce cardiac workload; cornerstone of heart failure treatment
- Beta Blockers (Carvedilol, Bisoprolol, Metoprolol): Slow heart rate, improve cardiac efficiency
- Diuretics (Furosemide/Lasix, Torsemide): Remove excess fluid to reduce breathlessness and leg swelling
- Spironolactone/Eplerenone: Potassium-sparing diuretics with mortality benefit in heart failure
- SGLT2 Inhibitors (Empagliflozin, Dapagliflozin): Now proven to reduce hospitalisation and death in heart failure
Medicines for Arrhythmia (Irregular Heart Rhythm)
- Digoxin: Slows heart rate in atrial fibrillation; narrow therapeutic window — regular digoxin level monitoring needed
- Amiodarone: Powerful antiarrhythmic; requires thyroid, liver, and lung function monitoring due to side effects
- Flecainide, Propafenone: Used for certain supraventricular arrhythmias
Key Safety Rules for Cardiac Patients
- Never stop cardiac medicines without consulting your cardiologist
- Always carry a list of your medicines
- Tell your dentist and surgeon about blood thinners before any procedure
- Avoid NSAIDs (ibuprofen, diclofenac) — they raise blood pressure and risk of heart attacks
- Limit alcohol — it interacts with many cardiac medicines
