What is isolated systolic hypertension?
The JNC VII (Seventh Report of the Joint National Committee on Prevention, Evaluation and Treatment of High Blood Pressure) emphasizes the importance of isolated systolic hypertension, defined as systolic blood pressure greater than or equal to 140 mmHg and diastolic blood pressure below 90 mmHg from 60.
How important is the systolic blood pressure?
Systolic blood pressure is considered the main component prognosis of hypertension.
Systolic pressure increases linearly from 30 years onwards, while diastolic increases until age 50 and then goes down. Therefore, pulse pressure, the difference between them, which increases throughout life, accelerating the increase from 50 years and is emerging as a reliable predictor of cardiovascular complications of hypertension than diastolic blood pressure .
Is it beneficial in the treatment of isolated systolic hypertension?
PAS has traditionally been undervalued as a cardiovascular risk factor and treatment as harmful by excessive decrease in DBP involved, considering that there may be a poor perfusion in the different organs. However, we have seen, on the contrary, treatment of isolated systolic hypertension is associated with reduced cardiovascular mortality by 22%, coronary mortality by 26% and stroke by 33%.
Treatment of isolated systolic
Most patients require more than one drug to control hypertension. The JNC VII emphasizes the need for early combination therapy, selecting substances with a mechanism of action, such as the association of calcium antagonists with diuretics or ACE inhibitors.
