What is the best medication for an enlarged heart?

There is no single best medication for treating an enlarged heart; the choice of drug should be based on the specific underlying cause and individual patient factors.

If the enlarged heart is caused by high blood pressure, commonly used medications include angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs), which help lower blood pressure and improve myocardial remodeling. Beta-blockers can reduce heart rate and decrease myocardial oxygen consumption.

If heart enlargement is due to heart failure, diuretics may be used to reduce fluid retention and relieve the heart's workload, while aldosterone receptor antagonists can help improve ventricular remodeling. If the cause is coronary artery disease, antiplatelet drugs and statins may be required.

Note: Always consult a doctor before starting any medication.
