Over the next 10 years, an estimated 45,000 quality-adjusted life-years and £850m health and social care costs could be saved, if England saw a 5 mmHg reduction in the average population systolic blood pressure. In addition, substantial reductions in death and disability could be achieved if there was a step change in our approach to detection and treatment of hypertension. This is the rationale behind the Blood Pressure Action Plan that was published recently.
