Vasodilators, also called blood vessel dilators, are drugs that cause the blood vessels (especially the arterioles) to expand in an effort to lower blood pressure and reduce the heart's workload. ACE inhibitors and nitrates are types of vasodilators.
Systolic blood pressure refers to the highest blood pressure measured in the arteries and occurs during the pumping phase of the heartbeat. It is measured in millimeters of mercury (mmHg) and is the upper number in the standard blood pressure reading. For example, in a blood pressure reading of ...
Angina is chest pain or discomfort due to coronary heart disease. It occurs when the heart muscle doesn’t get as much blood as it needs. This usually happens because one or more of the heart’s arteries is narrowed or blocked, also called ischemia. Stable angina refers to “predictable” chest ...
A balloon angioplasty is a medical procedure in which a balloon is used to open narrowed or blocked blood vessels of the heart, known as coronary arteries. A long, slender tube called a catheter with a deflated balloon on its tip is passed into the narrowed artery segment. Then the balloon is ...
Atherosclerosis is a form of arteriosclerosis in which the inner layers of artery walls become thick and irregular because of deposits of fat, cholesterol and other substances. This buildup is called plaque and can cause arteries to narrow, reducing the blood flow through them. Eventually plaque ...
Angiotensin-converting enzyme inhibitors, also called ACE inhibitors, are drugs used to treat high blood pressure and heart failure. ACE inhibitors s alters the body's ability to produce angiotensin II, a hormone that causes the arteries to narrow. By blocking the making of angiotensin, these drugs ...

Prehypertension is when blood pressure (the pressure of the blood against the walls of the arteries) is consistently ranging 120-139/80-89. People with pre-hypertension are likely to develop high blood pressure unless steps are taken to control it. Blood pressure is optimal at less than 120/80 and ...
