Arterial hypertension is one of the most important and preventable causes of death worldwide; therefore, adequate treatment of high blood pressure should be mandatory for patients with hypertension. Hypertension is defined on the basis of systolic and diastolic blood pressure levels and classified into stages on the basis of the degree of elevation. Normal blood pressure is widely considered as being less than 120/80 mm Hg. The presence of risk factors such as elevated blood cholesterol, smoking, diabetes, and obesity greatly increases the risk for hypertension-related morbid events.
Cardiovascular disease and stroke disproportionately affect older adults. Blood pressure is a potent modifiable target for reducing the risk for stroke and cardiovascular morbidity and mortality in older adults. In clinical trials, the number needed to treat to prevent one cardiovascular death was 79, one fatal or nonfatal stroke was 48, and one fatal or nonfatal coronary event was 64.
Key words: blood pressure, myocardial infarction, CVA, cardiovascular risk, older adults.
