The definition of lower blood pressure has evolved significantly over the years, particularly with the updates in hypertension guidelines. The 2017 American College of Cardiology/American Heart Association (ACC/AHA) guidelines redefined hypertension by lowering the threshold from 140/90 mmHg to 130/80 mmHg for systolic/diastolic blood pressure. This change was based on epidemiological evidence suggesting that lower blood pressure is associated with reduced cardiovascular risk, although the benefits of antihypertensive therapy at these lower targets are still debated. The concept of “the lower the better” has been challenged due to insufficient evidence from randomized controlled trials supporting significant outcome benefits at these lower targets. Despite this, systematic reviews and meta-analyses have shown that lowering blood pressure can significantly reduce the risk of major cardiovascular events, coronary heart disease, stroke, and heart failure, supporting the adoption of lower blood pressure targets in clinical practice.
