Umxhuzulane uyigcina njani intliziyo?

Uphononongo olutsha olupapashwe ngoMvulo yi-Journal of Circulation ye-American Heart Association yabika ukuba i-astronaut uScott Kelly, owachitha unyaka kwindawo, wayenentliziyo eyanciphayo nangona esebenza iintsuku ze-6 ngeveki ngexesha lokuhlala kwakhe.

Ukongeza, abaphandi babone utshintsho olufanayo entliziyweni yendadi yaseFransi uBenoit Lecomte, emva kokuba egqibe ukuqubha iintsuku ezili-159 ukuwela uLwandlekazi lwePasifiki ngo-2018.

Iziphumo zibonise ukuba ubunzima bexesha elide butshintsha isakhiwo senhliziyo, kubangela ukuchithwa kunye ne-atrophy, kwaye ukuzivocavoca okuphantsi akwanele ukukhusela oku kungenzeki.

Umxhuzulane ugcina intliziyo

Ngokophononongo olupapashwe yi-CNN, ngumxhuzulane osemhlabeni onceda intliziyo igcine ubungakanani kunye nokusebenza kwayo, njengoko igcina igazi limpompa ngemithambo, kwanezinto ezilula ezifana nokuma nokuhamba zinceda ukutsalela igazi emilenzeni.

Nangona, impendulo yesihlunu sentliziyo iyancipha xa icandelo lomxhuzulane lithatyathelwa indawo kukungabi nabunzima.

U-Kelly wayehlala kwi-zero gravity kwi-International Space Station ukusuka nge-27 kaMatshi 2015 ukuya ku-Matshi 2016, XNUMX, kwaye waqeqeshwa kwibhayisekile emileyo kunye ne-treadmill kunye nokubandakanya imisebenzi yokumelana nenkqubo yakhe yeentsuku ezintandathu ngeveki iiyure ezimbini ngosuku ngalunye.

Ngokwahlukileyo koko, ukusuka nge-5 kaJuni ukuya kwi-11 kaNovemba ka-2018, uLecomte wadada iimayile ezingama-1753, umyinge weeyure ezintandathu ngosuku. Lo msebenzi uqhubekayo unokubonakala unzima, kodwa yonke imihla yokuqubha ithathwa njengomsebenzi ophantsi.

Nangona le ndadi yaseFransi yayisemhlabeni, yachitha iiyure zosuku lwayo emanzini, ilungisa imiphumo yomxhuzulane. Abantu abaqubha umgama omde basebenzisa ubuchule obuqhelekileyo, obububuso obuthe tye ukuze baqubhe.

Umthambo ugcina intliziyo ilungile

Kwakhona, abaphandi babelindele ukuba imisebenzi eyenziwa ngamadoda omabini iya kugcina iintliziyo zabo nakuphi na ukucutha okanye ubuthathaka. Bobabini uKelly kunye noLecomte baye bafumana ilahleko yobunzima kunye nokuncipha kokuqala kobubanzi kwiiventricles zasekhohlo zentliziyo ngexesha lovavanyo lwabo.

Zombini i-spaceflights ezide kunye nokuntywila okude emanzini kwakhokelela ekulungelelaniseni okuthe ngqo kwentliziyo, watsho umbhali okhokelayo wokufunda uGqr Benjamin Levine, unjingalwazi wezonyango zangaphakathi kunye ne-cardiology kwiYunivesithi yaseTexas Southwestern Medical Centre.

Ngelixa ababhali beqaphela ukuba bafunde kuphela amadoda amabini awenza izinto ezingaqhelekanga, uphononongo olungakumbi luyafuneka ukuze kuqondwe indlela umzimba womntu osabela ngayo kwiimeko ezinzima.

Akukho siphumo esibi

Kule meko, abaphandi babona ukuba intliziyo iguqulelwe, kodwa ukuchithwa akuzange kubangele nayiphi na imiphumo ekhoyo okanye yexesha elide.

Intliziyo iya isiba ncinci, incipha kwaye ibe buthathaka, kodwa ayibi buthathaka - kulungile, ”utshilo uLevine, okwangumlawuli weZiko lokuSebenza kunye neNdalo yokuSingqongileyo.

Wongezelela ukuba ekubeni umzimba ujwayele ukumpompa igazi ukuya phezulu ngokuchasene nomxhuzulane kwindawo ethe nkqo, xa lo mxhuzulane ususiwe, ngakumbi kumntu osele esebenza kwaye efanelekile, intliziyo ilungelelanisa lo mthwalo omtsha. Wachaza ukuguquguquka kunye nokuguquguquka kwemisipha yentliziyo, malunga neekota ezintathu ze-muscle eziphendula kumsebenzi womzimba.

Kwakhona wachaza ukuba i-heart muscle iqhelana neenqwelomoya, ukuzivocavoca, kunye nokuphakama okuphezulu, njengoko lilungu eliguquguqukayo ngokuphawulekayo eliphendula kwiimfuno ezibekwe phezu kwayo.

Waqukumbela ngokuchaza ukuba ubukhulu bentliziyo buyanda njengoko umthwalo kuwo ukhula, kwaye kwenzeka into efanayo kwicala elichaseneyo.
