[This guideline is a comprehensive USA update. High BP now starts at 130/80, based on 1000 recent studies, inc. SPRINT [ref. 37 below, 2015], These show that aggressively treating BP down to 120 mm Hg saves lives. This means another 14% of Americans will be diagnosed with high BP. Only 2% more will need prescriptions as this part of guideline relies heavily on lifestyle changes. It also calls for more team-based medicine, more reliance on telehealth and “between appointment” monitoring of blood pressure. So, get patients to take their BP at home. Take a patient’s BP more than once before diagnosing high blood pressure. “Lifestyle management is the challenge and the underlying issue for high BP, and we have to come to grips with it.” The guideline says a healthy lifestyle is: the DASH diet, which promotes fruits and vegetables, low-fat or non-fat dairy, whole grains, and less than 1500 mg of daily sodium (salt). Limit alcohol to 2 drinks a day for men and 1 per day for women. Exercise at least 30 minutes 3 times a week].
