Lisinopril is an angiotensin-converting enzyme, which helps to clean chemicals that cause tightening of the blood vessels out of your system. This will allow your blood to flow smoothly and put less pressure on the heart so that your heart can pump more efficiently. This medication is often prescribed to those with high blood pressure or recovering from heart failure and heart attack. These medications will help you manage your symptoms, but it will not cure them. You will need to talk with your doctor about what long term care will be necessary in order to manage your condition.
