Izikhokelo ezihlaziyiweyo ezikhutshwe yiZiko leSizwe lezeMpilo zijolise kwiinjongo zengcinezelo yegazi ekulawuleni uxinzelelo lwegazi. Uphononongo oluphawulekayo lubonakalise ukuba uxinzelelo lwegazi lwe-systolic elingaphantsi kwama-millimitha angama-mercury (mm Hg) lwaluphumelele ngakumbi ekunciphiseni isifo kunye nesifo senhliziyo kunokuba bekujoliswe ku-140 mm Hg.
Yintoni oku kuthetha ngayo kuwe
Iingcebiso ezihlaziyiweyo zithetha ukuba ugqirha wakho ngoku unolwazi malunga noxinzelelo olufanelekileyo lwegazi oluhlukileyo nolwazi lwentlalo yezokwelapha ngaphambi kokuba iziphumo zophando zophando zifumaneke.
Ngokubhekiselele kwimpilo yakho, oku kuthetha ukuba ukuba uxinzelelo lwegazi lwe-systolic lungaphezu kwe-120 mg Hg, ugqirha wakho unokuguqula umthamo weyeza zakho ezichasene negazi , ungeze iyeza elitsha, okanye unokutshintsha amayeza akhoyo ayeza kumachiza ahlukeneyo ukuze ufikelele kwiinjongo eziphilileyo.
Kutheni Izikhokelo zibuyekeziwe
Izikhokelo ezihlaziyiweyo zisekelwe kwiphando elibalulekileyo elibizwa ngokuba yi-SPRINT trial. Icaleni le-SPRINT lwenziwa phakathi kuka-2010-2013, elibandakanya izigulane ezingama-9361 ezivela kwiindawo ezili-102 ezahlukahlukeneyo kulo lonke elaseUnited States. Bonke abathathi-nxaxheba bafumanisa ukuba banengcinezelo yomshushu kwaye banesondlo segazi se-systolic phakathi kwe-150 mm Hg ne-180 mm Hg ekuqaleni kwesi sifundo. Uxinzelelo lwegazi lwe-Systolic liphezulu kwinani legazi. Ngoko ukuba uxinzelelo lwegazi luyi-160/80, ke uxinzelelo lwegazi lwe-systolic ngu-160 mm Hg.
Amavolontiya okufundela ahlukaniswe ngamaqela amabini-elinye iqela elijoliswe ngu-140 mm Hg (iqela lokunyanga eliqhelekileyo) kunye nelinye iqela elijoliswe nguxinzelelo lwe-120 mm Hg (iqela elininzi lokunyanga.) Isicwangciso sokuqala kwakukujonga abathathi-nxaxheba malunga neenyanga ezintathu ukuya kwiminyaka emi-5.
Nangona kunjalo, iqela elikhulu lokunyanga lenza ngcono kangcono kunokuba iqela lokunyanga eliqhelekileyo abaphandi baphelisa isifundo emva kweminyaka engaphezu kwe-3 endaweni yokugqiba iphrojekthi ye-5. Iqela lokunyanga eliqhelekileyo lalingamazinga angaphezulu kwama-43% okufa kunokuba iqela elikhulu lonyango. Ulawulo olunzulu lokulawula uxinzelelo lwegazi kunye nenjongo yesondlo segazi lwe-systolic engaphantsi kwe-120 mm Hg kubangele ukufa kwabantu abancinci, isifo senhliziyo kunye nezinye izizathu zonyango.
Uxinzelelo lwegazi oluphezulu luchaphazela njani ingozi yakho yesifo
Uxinzelelo lwegazi oluphezulu (uxinzelelo lwegazi) ngumqathango ongafanelekanga kwiintliziyo eziqhelekileyo kunye nokusebenza kweseva yegazi. Uxinzelelo lwentliziyo lubangela isifo senhliziyo, esibangela ukubetha. Uxinzelelo lwentliziyo luwonakalisa imithwalo yegazi engqondweni, obangela imeko ebizwa ngokuba yi- cerebrovascular disease , eyazimela ngokuzimeleyo kwaye yongeza umngcipheko wesifo xa unesifo senhliziyo. Ngako oko, kuye kwaziwa ngexesha elithile ukuba ingozi yempembelelo yingozi yengozi. Nangona kunjalo, yintoni into entsha ukuba i-target mm 140mm Hg sysilic blood pressure yayingekho efanelekileyo ngokwaneleyo ukukhusela ngokuthe tye.
Ngaba Ufanele Ukhathazeke Ngeempembelelo Zecandelo Lolawulo Oluxinzelelekileyo Lwegazi?
Kukho iziphumo eziphantsi kwexinzelelo lwegazi eliphantsi. Abanye abathathi-nxaxheba kumabini omabili kwi-trial ye-SPRINT babenemiphumo emibi yexinzelelo lwegazi eliphantsi (i-hypotension) njengobunzima bokukhanya, ukuva ukuphazamiseka komonakalo kunye neentso, nangona izigulane ezinengxaki yegazi phantsi kwe-120 mm Hg yexinzelelo lwegazi nemiphumo emibi yecala ye-hypotension kuneqela elijoliswe phantsi kwe-140 mm Hg.
Ngokubanzi, ukuba unesifo sengqondo somxholongwane, kufuneka ukulindele ingcinezelo yegazi ehlukile kunokuba unayo ngaphambili ukuze uthintele ukukhuselwa kwesifo nesifo senhliziyo.
Nangona iziphumo zempembelelo yegazi ephantsi aziqhelekanga, kuluvo oluhle ukuba uqhelane nempawu kunye neempawu ze-hypotension, ezinobunono obunzima, ukuxakeka kwegazi kwaye uziva uphelile okanye udlulile.
