ACE Inhibitors and Angiotensin II Receptor Blockers (ARBs): Help relax blood vessels, reduce blood pressure, and decrease the workload on the heart. Antiarrhythmic Drugs: Manage abnormal heart rhythms (arrhythmias), ensuring that the heart beats properly. Anticoagulants (Blood Thinners): Prevent blood clots in patients with certain heart conditions, such as congenital heart defects or arrhythmias.
