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 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 .
