Nearly half of U.S. adults have high blood pressure

ANAHEIM, Calif. — New discipline reduce a threshold for high blood pressure, adding 30 million Americans to those who have a condition, that now plagues scarcely half of U.S. adults.

High pressure, that for decades has been a tip reading of during slightest 140 or a bottom one of 90, drops to 130 over 80 in recommendation announced Monday by a dozen medical groups.

The guidelines, announced during an American Heart Association discussion in Anaheim, meant an additional 14 percent of U.S. adults have a problem, yet usually 2 percent of these newly combined people need remedy right away; a rest should try healthier lifestyles, that get most stronger importance in a new advice. Poor diets, miss of practice and other bad habits means 90 percent of high blood pressure.

“I have no doubt there will be controversy. I’m certain there will be people saying, ‘We have a tough adequate time removing to 140,'” pronounced Dr. Paul Whelton, a Tulane University medicine who led a discipline panel.

But a risk for heart disease, stroke and other problems drops as blood vigour improves, and a new recommendation “is some-more honest” about how many people have a problem, Whelton told CBS News arch medical match Dr. Jon LaPook.

The tip threshold for high blood vigour has been 140 given 1993, yet a vital investigate dual years ago found heart risks were most reduce in people who directed for 120. Canada and Australia lowered their cutoff to that; Europe is still during 140 yet is due to correct a superintendence subsequent year.

Currently, usually half of Americans with high blood vigour have it underneath control. Dr. Whelton pronounced a additional patients now personal as carrying hypertension should be means to conduct their condition with diet and lifestyle changes alone.

“Most of them only need to know they’re during high risk, yet they can conduct that problem on their own,” Whelton told LaPook.

At a health satisfactory in New York City Monday, Adrienne Williams unexpected found herself with a new diagnosis of hypertension, her blood vigour in a 130s.

“Hypertension is deliberate a wordless torpedo and now it’s something we need to research, and we wouldn’t have famous that had we not stopped by today,” Williams said.

What a changes mean

The discipline set new categories and get absolved of “prehypertension”:

  • Normal: Under 120 over 80
  • Elevated: Top series 120-129 and bottom reduction than 80
  • Stage 1: Top of 130-139 or bottom of 80-89
  • Stage 2: Top during slightest 140 or bottom during slightest 90

That means 46 percent of U.S. adults have high vigour (stages 1 or 2) contra 32 percent underneath a aged levels.

How common it is will roughly triple in group underneath 45, to 30 percent, and double in women of that age, to 19 percent.

For people over 65, a discipline remove a argumentative tweak done 3 years ago to relax standards and not start medicines unless a tip series was over 150. Now, everybody that aged should be treated if a tip series is over 130 unless they’re too thin or have conditions that make it unwise.

“The justification with this is so solid, so convincing, that it’s tough to disagree with a targets,” pronounced Dr. Jackson Wright, a discipline row member from University Hospitals Cleveland Medical Center. Older people “have a 35-to-50-fold aloft risk of failing of a heart attack or cadence compared to younger people.”

But a Cleveland Clinic’s Dr. Steven Nissen pronounced he’s worried.

“Some some-more exposed patients who get treated really aggressively might have difficulty with falls” since too-low vigour can make them faint, he said.

Who needs treatment

Certain groups, such as those with diabetes, should be treated if their tip series is over 130, a discipline say. For a rest, either to start remedy will no longer be formed only on a blood vigour numbers. The preference also should cruise a altogether risk of carrying a heart problem or cadence in a subsequent 10 years, including factors such as age, gender and cholesterol, regulating a elementary regulation to guess those odds.

Those though a high risk will be suggested to urge their lifestyles — remove weight, eat healthy, practice more, extent alcohol, equivocate smoking.

“It’s not only throwing meds during something,” pronounced one primary caring alloy who praised a new approach, a Mayo Clinic’s Dr. Robert Stroebel. If people continue bad habits, “They can kind of eat and blow by a medicines,” he said.

The discipline advise about some renouned approaches, though. There’s not adequate explanation that immoderate garlic, dim chocolate, tea or coffee helps, or that yoga, meditation or other function therapies reduce blood vigour long-term, they say.

The supervision no longer writes heart guidelines, withdrawal it to medical groups. Unlike prior guideline panels, nothing on this one have new financial ties to industry, nonetheless some on a row that reviewed and commented on them do.

The discipline were published in dual journals — Hypertension and a Journal of a American College of Cardiology.

How and when to check it

Blood vigour should be checked during slightest once a year by a health professional, and diagnosing high vigour requires 2 or 3 readings on during slightest dual occasions.

The common approach uses a slap on a tip arm to temporarily retard a upsurge of blood in an artery in a arm and gradually recover it while listening with a stethoscope and counting sounds a blood creates as it flows by a artery. But that is disposed to error, and many places now use programmed devices.

The discipline don’t collect a method, yet suggest measuring vigour in a tip arm; inclination that work on fingers or are ragged on wrists “aren’t prepared for primary time,” Whelton said.

Home monitoring also is recommended; inclination cost as small as $40 to $60.

What about kids?

Unlike adults, numbers for normal pressure in children change with age, tallness and gender. Kids should be checked during slightest once a year for high pressure, contend discipline announced in Aug by a American Academy of Pediatrics.

After age 13, a levels defining high vigour are a same as for adults, pronounced a member of a pediatrics panel, Dr. Elaine Urbina of Cincinnati Children’s Hospital Medical Center.

“When we spin 18 years and one minute, we shouldn’t unexpected have a new definition,” she said.
