Two common classes of blood pressure medications angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs)—are equally effective at controlling high blood pressure, according to a report released today by the Agency for Healthcare Research and Quality.
The report, which analyzed published results from 61 studies, also found that ACEIs are slightly more likely than ARBs to cause a harmless but persistent dry cough.
Authors of the report also said that more research is needed to learn how ACEIs and ARBs may differ when it comes to longer term benefits and harms. In particular, more information is needed about how the medications may differ in decreasing the risks of heart attack, stroke, or death.
Blood pressure is the force of blood pushing against artery walls. The cause of high blood pressure (140/90 mmHg or higher) is often unknown. Systolic pressure measures pressure during a heartbeat. Diastolic pressure measures pressure between beats. Because it typically has no symptoms, high blood pressure—also known as hypertension—is often called “the silent killer.”
About one-third of the adult population – have high blood pressure. If left untreated, high blood pressure can cause catastrophic health problems: the heart may enlarge, which can lead to heart failure; small bulges – aneurysms – may form in blood vessels, including the aorta (the main artery to the heart) and others in the brain, legs, and intestines; blood vessels in the kidney may narrow, causing kidney failure; blood vessels in the eyes may burst or bleed, possibly leading to blindness; and arteries throughout the body may “harden” faster, potentially leading to heart attack or stroke.
