Arterial hypertension is a major cause of morbidity and mortality because of its association with coronary heart disease, cerebrovascular disease and renal disease. The extent of target organ involvement (i.e. heart, brain and kidneys) determines outcome. North American studies have shown that hypertension is a major contributor to 500 000 strokes (250 000 deaths) and 1 000 000 myocardial infarctions (500 000 deaths) per annum.
