ADA Position Statement on Diabetes, Hypertension
October 13, 2017
ANAHEIM, CALIF. – Thirty million Americans became hypertensive overnight on Nov. 13 with the introduction of new high blood pressure guidelines from the American College of Cardiology and American Heart Association.
That happened by resetting the definition of adult hypertension from the long-standing threshold of 140/90 mm Hg to a blood pressure at or above 130/80 mm Hg, a change that jumps the U.S. adult prevalence of hypertension from roughly 32% to 46%. Nearly half of all U.S. adults now have hypertension, bringing the total national hypertensive population to a staggering 103 million.
But the new guidelines (J Am Coll Cardiol. 2017 Nov 13. doi:) for preventing, detecting, evaluating, and managing adult hypertension do lots more than just shake up the epidemiology of high blood pressure. With 106 total recommendations, the guidelines seek to transform every aspect of blood pressure in American medical practice, starting with how it’s measured and stretching to redefine applications of medical systems to try to ensure that every person with a blood pressure that truly falls outside the redefined limits gets a comprehensive package of interventions.
“The systolic blood pressure goal for older people has gone from 140 mm Hg to 150 mm Hg and now to 130 mm Hg in the space of 2-3 years,” commented Dr. Appel, professor of epidemiology at Johns Hopkins University in Baltimore and not involved in the guideline-writing process.
In fact, the guidelines simplified the treatment goal all around, to less than 130/80 mm Hg for patients with diabetes, those with chronic kidney disease, and the elderly; that goal remains the same for all adults.
“It will be clearer and easier now that everyone should be less than 130/80 mm Hg. You won’t need to remember a second target,” said , a nephrologist and professor of medicine at the Mayo Clinic in Rochester, Minn., and a member of the guidelines task force.
“Some people may be upset that we changed the rules on them. They had normal blood pressure yesterday, and today it’s high. But it’s a good awakening, especially for using lifestyle interventions,” Dr. Taler said .
Lifestyle optimization is repeatedly cited as the cornerstone of intervention for everyone, including those with elevated blood pressure with a systolic pressure of 120-129 mm Hg, and as the only endorsed intervention for patients with hypertension of 130-139 mm Hg but below a 10% risk for a cardiovascular disease event during the next 10 years on the American College of Cardiology’s online risk. The guidelines list six lifestyle goals: weight loss, following a diet, reducing sodium, enhancing potassium, 90-150 min/wk of physical activity, and moderate alcohol intake.
