Ideal Target Blood Pressure in Hypertension
In the Systolic Blood Pressure Intervention Trial (SPRINT), intensive blood pressure (BP) lowering was associated with significant reduction in composite cardiovascular (CV) outcomes in hypertension. Subsequently, several meta-analyses have corroborated the findings from SPRINT and these benefits were more prominent in subjects with higher cardiovascular risk at baseline. As such, the recent American College of Cardiology (ACC)/American Heart Association (AHA) hypertension guideline and the European Society of Hypertension (ESH)/European Society of Cardiology (ESC) guideline recommended the lowering of target BP to less than 130/80 mmHg in most hypertensive subjects. However, one should keep in mind the potential harm of too much BP lowering. Post hoc analysis of clinical trials have demonstrated increased cardiovascular mortality and events with too much BP lowering. Therefore, although intensive BP lowering may be beneficial in further reducing CV outcomes, too much reduction below 120/70 mmHg may actually harmful. In conclusion, although intensive BP lowering to achieve target BP below 130/80 mmHg is beneficial in reducing CV outcomes, one should do so cautiously as to avoid adverse events. As such, the first target of anti-hypertensive treatment should be to achieve BP lowering below 140/90 mmHg. Once that target is achieved, one could target BP below 130/80 mmHg keeping in mind to avoid signs of organ hypoperfusion such as orthostatic hypotension, orthostatic dizziness, weakness and serum creatinine elevation.
