Optimal blood pressure: how low should we go?

摘要: The Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure defines hypertension as systolic blood pressure > or =140 mm Hg diastolic (DBP) =90 Hg. Evidence shows that even slightly elevated significantly increases the risk morbidity mortality only aggressive efforts to reduce can this risk. In recently completed Hypertension Optimal trial, patients were assigned one three target groups, reflecting DBP goals < =90, =85, =80 Aggressive antihypertensive treatment allowed more than 90% achieve goal This study clearly showed these defined could be safely met exceeded. Too few with receive level effective achieved in clinical trials. Individuals poorly controlled are at significant for cardiovascular cerebrovascular represent a potentially substantial burden healthcare system. Setting appropriate working meet them through treatment, multiple agents if necessary, those risks.
