 All participants will be prescribed Lisinopril 10mg per day or higher depending on your blood pressure as part of regular care for their condition. If they are already on another ACEI, Lisinopril will be prescribed. If subjects are unable to tolerate Lisinopril or other ACEI medications, an angiotensin receptor blocker ARB will be prescribed. ARBs are another type of medication that also helps relax blood vessels if subjects cannot tolerate ACEI medications.
