[Renal and cardiovascular protection associated to antihypertensive treatment in the elderly]. / Protección cardiovascular y renal asociada al tratamiento antihipertensivo en el anciano.

The incidence of arterial hypertension increases with age in such a way that by the age of 60 the incidence is greater than 50% in men and women. This increase is particularly relevant if we consider the changes in systolic blood pressure (increase) and diastolic blood pressure (decrease) in relation to age and as a consequence in the reduction of vascular compliance which is common in men and women over the age of 60. These disorders are associated to artheriosclerosis and the corresponding increase in pulse pressure. It is for these reasons that the most common form of hypertension is isolated systolic hypertension (SBP > 140 mmHg and SBP < 90 mmHg), which represents 50% of hypertensive patients in the elderly population. Isolated systolic hypertension is also associated to an increase in cardiovascular disease (MI, stroke), increasing the risk of mortality four times. In elderly people, hypertension and isolated systolic hypertension are risk factors that can be managed. Today there is sufficient evidence from clinical trials that show a clear benefit in the reduction of the cardiovascular and renal risk associated to the antihypertensive treatment in the elderly, at least when the blood pressure is greater than 160/90 mmHg. The target blood pressure figures to control in the elderly person, probably below 160/90 mmHg, still need to be determined.
