In populations, blood pressures fit a normal distribution, but the attendant risks of heart disease and stroke increase curvilinearly with increasing levels of blood pressure, without any obvious breakpoint ( Fig. 63-1 ). Thus, the separation of normal from high blood pressure is arbitrary, and the definition of hypertension has been a moving target.

Blood pressure is the force with which blood pushes against the artery walls as it travels through the body. Like air in a balloon, blood fills arteries to a certain capacity—and just as too much air pressure can cause damage to a balloon, too muc...

Hypertension is the term used to describe high blood pressure. Blood pressure readings are measured in millimeters of mercury (mmHg) and usually given as two numbers. For example, 120 over 80 (written as 120/80 mmHg. The top number is your systoli...

Also known as high blood pressure, a condition in which too much force is exerted by the blood as it travels through the body's arteries. There are two types of hypertension: primary and secondary. Primary, or essential, hypertension is caused by ...

Hypertension is an independent risk factor for coronary artery disease (CAD) and stroke, leading causes of morbidity and mortality in North America. Concern has been raised that there is inadequate outpatient detection, evaluation, and treatment of hypertension, and that this is resulting in increased hospital admissions with complications of untreated hypertension: heart failure, and end-stage renal disease .

A heart attack is when blood vessels that supply blood to the heart are blocked, preventing enough oxygen from getting to the heart. The heart muscle dies or becomes permanently damaged. Your doctor calls this a myocardial infarction.
