angiotensin-converting enzyme (ACE) inhibitors

Angiotensin-converting enzyme (ACE) inhibitors are medications that help lower blood pressure and protect the heart. They work by blocking a protein called ACE, which normally helps produce a substance that tightens blood vessels. By inhibiting this protein, ACE inhibitors cause blood vessels to relax and widen, making it easier for blood to flow. This reduces the workload on the heart and helps prevent heart failure, stroke, and kidney problems. They are commonly prescribed for conditions like hypertension (high blood pressure) and heart failure, providing cardiovascular protection through these effects.
