Isifo senhliziyo singumbulali wokuqala kwabesifazane e-U.S futhi ngenkathi izinkinga ze-coronary zivame ukuhlotshaniswa nokuguga, izinto ezinomthelela zingaqala ngaphambi kwesikhathi empilweni. Imbangela eyodwa ebalulekile: amazinga aphezulu e-cholesterol "embi", i-aka LDL cholesterol (low-density lipoprotein). Nakhu ukuthi kusebenza kanjani: Lapho abantu bedla ukudla okune-cholesterol eningi, kanye nokudla okunamafutha ashubile nalawo agcwele (cabanga okuthile emigqeni emhlophe, "amafutha"), i-LDL ingena emithanjeni yegazi. Wonke lawa mafutha athe xaxa angagcina ekugcineni kwezindonga zomthambo, kudale izinkinga zenhliziyo ngisho nohlangothi. Nansi indlela yokuthatha isinyathelo manje ukuze uthole impilo ephelele yenhliziyo ukuze ukwazi ukuvimbela isifo senhliziyo kamuva.

UKWAZI IZISEKO

Nali iqiniso elisabisayo: Ucwaningo olwenziwe yi-GfK Custom Research eNyakatho Melika luthole ukuthi cishe amaphesenti angama-75 abesifazane abaneminyaka eyi-18 kuya kwengama-44 bebengazi umehluko phakathi kwe-cholesterol "enhle", noma i-HDL (i-high-density lipoprotein), ne-LDL. I-cholesterol embi ingakha egazini ngenxa yokudla ukudla okunamafutha, ukungazivocavoci ngokwanele kanye / noma ukuphendula ezinye izinkinga zempilo, kwakheke uqweqwe emithanjeni. Ngakolunye uhlangothi, umzimba empeleni udinga i-HDL ukuze uvikele inhliziyo futhi ususe i-LDL esibindini nasemithanjeni. Kwabesilisa nabesifazane, i-cholesterol ngokujwayelekile ingalawulwa ngokudla okunempilo nokuvivinya umzimba-yize kwesinye isikhathi imishanguzo kadokotela iyadingeka.

UKUHLOLWA

Kunconywa ukuthola ukuhlolwa okuyisisekelo kwe-lipoprotein eminyakeni yakho yamashumi amabili - okuyindlela nje emnandi yokuhlolwa kwegazi ukuthola amazinga akho e-LDL ne-HDL. Odokotela abaningi bazokwenza lolu vivinyo njengengxenye yomzimba okungenani njalo eminyakeni emihlanu futhi kwesinye isikhathi kaningi uma kunezici zobungozi ezikhona. Ngakho-ke ayini amazinga we-cholesterol enempilo? Okufanelekile, i-cholesterol embi kufanele ibe ngaphansi kuka-100 mg / dL. Kwabesifazane, amazinga e-cholesterol angaphansi kuka-130 mg / dL asalungile-yize udokotela kungenzeka ancoma ushintsho lokudla nokuvivinya umzimba kunoma yimaphi amazinga angaphezu kwaleyo nombolo. I-flip side: Nge-cholesterol enhle, amazinga aphezulu angcono futhi kufanele abe ngaphezu kuka-50 mg/dL kwabesifazane.

UKWAZI IZINGOZI ZAKHO

Kukholwe noma ungakukholwa, abesifazane abanesisindo esinempilo-noma ngisho nabesifazane abakhuluphele-bangaba namazinga aphezulu e-LDL. Ucwaningo luka-2008 olushicilelwe ku- I-American Journal of Human Genetics kutholakale ukuthi kukhona ukuxhumana kofuzo phakathi kwe-cholesterol embi, ngakho-ke abesifazane abanomlando womndeni wesifo senhliziyo kufanele baqiniseke ukuthi bayahlolwa, noma ngabe bancane. Kwabesilisa nabesifazane, ingozi ephezulu ye-cholesterol nayo ingakhuphuka nesifo sikashukela. Ukungatholi ukuzivocavoca umzimba ngokwanele, ukudla ukudla okunamafutha amaningi kanye / noma ukukhuluphala ngokweqile nakho kungaba nomthelela ekukhuleni kwamazinga e-LDL nokukhuphula ingozi yesifo senhliziyo. Ucwaningo luye lwabonisa nokuthi kwabesifazane, ubuhlanga bungadlala indima ekuguleni kwenhliziyo futhi abesifazane base-Afrika baseMelika, aboMdabu baseMelika nabaseSpain bathinteka kakhulu. Ukukhulelwa nokuncelisa kungase kwenyuse amazinga e-cholesterol yowesifazane, kodwa lokhu kungokwemvelo futhi akufanele kube yimbangela yokwesaba ezimweni eziningi.

UKUDLA UKUDLA KWEZEMPILO YENHLIZIYO

Kwabesifazane, i-cholesterol ephezulu ingakhonjwa ekukhetheni okungafanele kokudla okungalungile empilweni yenhliziyo yonke. Yini-ke ukukhetha okuhle kokudla? Thenga i-oatmeal, okusanhlamvu okuphelele, ubhontshisi, izithelo (ikakhulukazi lokho kudla okucebile nge-antioxidant, njengamajikijolo), nemifino. Cabanga ngale ndlela: Ukudla kungokwemvelo ngokwengeziwe futhi kuqukethe nefayibha eningi, kuba ngcono. Ama-salmon, ama-alimondi, namafutha omnqumo nakho kungukudla okuhlakaniphile, ngoba kulayishwa amafutha anempilo umzimba owadingayo. Kwabesifazane, i-cholesterol ephezulu ingaqhubeka nokuba yinkinga uma ukudla kususelwa ezinyameni ezinamafutha, ukudla okusetshenzisiwe, ushizi, ibhotela, amaqanda, amaswidi, nokuningi.

UKUSEBENZISA OKUFANELE

Ucwaningo lwaseBrithani oluphuma eBrunel University olushicilelwe ku Ijenali Yomhlaba Wonke Yokukhuluphala ithole ukuthi "izivocavoca ezinamafutha" zinamazinga aphilile, aphansi e-LDL kunalawo angancikile kokuzivocavoca. Ucwaningo luphinde lwaqinisekisa ukuthi izivivinyo ze-cardio njengokugijima nokuhamba ngebhayisikili yizinto ezisemqoka ekugcineni amazinga aphezulu we-cholesterol enhle namazinga aphansi we-cholesterol embi. Eqinisweni, ucwaningo lweminyaka eyisishiyagalolunye olwanyatheliswa kumagazini ka-August 2009 we I-Journal of Lipid Research bathola ukuthi kwabesifazane, i-cholesterol ephezulu inganqandwa ngehora elengeziwe lokuzivocavoca ngesonto.
