Catch­ing up on sleep over the week­end may not help the heart

The Garden Island - - Pau Hana Time -

ANA­HEIM, Cal­i­for­nia -— Us­ing the week­end to catch up on sleep may not be good for heart health, a new study sug­gests.

The study, pre­sented Tues­day at the Amer­i­can Heart As­so­ci­a­tion’s Sci­en­tific Ses­sions, in­cluded more than 21,000 older fe­male health care pro­fes­sion­als with­out a his­tory of car­dio­vas­cu­lar dis­ease or can­cer.

Those who spent two or more hours catch­ing up on sleep over the week­end — what re­searchers call “sleep debt” — were more likely to have poor car­dio­vascu- lar health.

Sleep ex­pert Marie-Pierre StOnge, Ph.D., said the find­ings sug­gest peo­ple who catch up on sleep over the week­end aren’t coun­ter­act­ing the harm­ful ef­fects of not get­ting enough sleep the rest of the week.

“You’re not re­ally sal­vaging your­self,” said St-Onge, an as­so­ciate pro­fes­sor of nu­tri­tional medicine at Columbia Univer­sity De­part­ment of Medicine in New York City, who was not part of the new study.

It’s best to get at least seven hours of sleep each night and to go to bed and wake at about the same time every day, she said.

Even af­ter re­searchers ac­counted for fac­tors such as in­come, ed­u­ca­tion and over­all stress, women with sleep debt were still worse off.

The news is es­pe­cially trou­bling be­cause women are liv­ing longer and re­port more sleep is­sues than men, said Michelle Al­bert, M.D., the study’s se­nior re­searcher and a pro­fes­sor of medicine at the Univer­sity of Cal­i­for­nia, San Fran­cisco. Women in the study were 72 years old on av­er­age.

Be­tween 50 and 70 mil­lion U.S. adults don’t get enough sleep or have sleep dis­or­ders, ac­cord­ing to es­ti­mates from the Na­tional Heart, Lung, and Blood In­sti­tute.

Among peo­ple with acute coro­nary syn­dromes, which in­cludes heart at­tacks and other sud­den block­ages of blood flow to the heart, about a third re­port hav­ing sleep dis­tur­bances, said Al­bert. She is the di­rec­tor of UCSF’s NUR­TURE Cen­ter, which con­ducts re­search re­lated to ad­ver­sity, so­cial de­ter­mi­nants of health and car­dio- in­dus­try, al­though some on a panel that re­viewed and com­mented on them do.

The guide­lines were pub­lished in two jour­nals — Hy­per­ten­sion and the Journal of the Amer­i­can Col­lege of Car­di­ol­ogy.

Blood pres­sure should be checked at least once a year by a health pro­fes­sional, and di­ag­nos­ing high pres­sure re­quires 2 or 3 read­ings on at least two oc­ca­sions.

The com­mon way uses a cuff on the up­per arm to tem­po­rar­ily block the flow of blood in an artery in the arm and grad­u­ally re­lease it while lis­ten­ing with a stetho­scope and count­ing sounds the blood makes as it flows through the artery. But that is prone to error, and many places now use au­to­mated de­vices.

The guide­lines don’t pick a method, but rec­om­mend mea­sur­ing pres­sure in the up­per arm; de­vices that work on fin­gers or are worn on wrists “aren’t ready for prime time,” Whel­ton said.

Home mon­i­tor­ing also is rec­om­mended; de­vices cost as lit­tle as $40 to $60.

Un­like adults, num­bers for nor­mal pres­sure in chil­dren vary with age, height and gen­der. Kids should be vas­cu­lar dis­ease.

Pre­vi­ous stud­ies of sleep and car­dio­vas­cu­lar dis­ease have mostly fo­cused on the to­tal amount of sleep, not sleep debt, Al­bert said.

A 2016 sci­en­tific state­ment from the Amer­i­can Heart As­so­ci­a­tion re­ported that not sleep­ing enough, ob­struc­tive sleep ap­nea and in­som­nia can in­flu­ence the risk of obe­sity, high blood pres­sure, Type 2 di­a­betes, stroke and coro­nary heart dis­ease. ••• Amer­i­can Heart As­so­ci­a­tion News checked at least once a year for high pres­sure, say guide­lines an­nounced in Au­gust by the Amer­i­can Acad­emy of Pe­di­atrics.

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

“When you turn 18 years and one minute, you shouldn’t sud­denly have a new def­i­ni­tion,” she said. ••• Associated Press
