ACE converts angiotensin I produced by the body to angiotensin II in the blood. Angiotensin II is a very potent chemical that causes the muscles surrounding blood vessels to contract and narrow the blood vessels. Narrowing of blood vessels increases the pressure within the blood vessels and may lead to high blood pressure (hypertension).
By reducing the activity of ACE, ACE inhibitors decrease the formation of angiotensin II which leads to widening (dilation) of blood vessels, and thereby reduces blood pressure. By lowering blood pressure against which the heart must pump, the amount of work that the heart must do is reduced. ACE inhibitors also reduce blood pressure in the kidneys, slowing the progression of kidney disease due to high blood p...
