Xa uxelela ugqirha wakho ngale nto, ngaba ukuxelele ukuba wenze "Uvavanyo Loxinzelelo Lokuzivocavoca"? Usenokuba uzive usoyika kwaye unexhala xa usiva elo gama. Xa sisiva igama elithi "uxinzelelo," sicinga ngento enzima. Kodwa oku akuyonto yokoyika. Olu luvavanyo oluqhelekileyo olusinika ulwazi oluninzi oluxabisekileyo malunga nempilo yentliziyo yakho, kwaye lwenziwa rhoqo. Ngoko masithethe ngale nto ngokucacileyo nangokulula namhlanje.
Ngamafutshane, yintoni uvavanyo loxinzelelo lokuzivocavoca?
Cinga ngenjini yemoto yakho. Xa ipakishwe nje, isenokubonakala ngathi isebenza kakuhle. Kodwa kuphela xa unyuka intaba okanye ukhawuleza apho uyazi ngokwenene ukuba kukho into engalunganga ngenjini. Kunjalo ke ngeentliziyo zethu.
Xa sihleli nje siphumle, intliziyo ayinamthwalo ungako kuyo. Kodwa xa sizilolonga, sibaleka, okanye sitsiba, amanye amalungu omzimba wethu afuna ioksijini negazi elingakumbi. Emva koko intliziyo kufuneka isebenze ngokukhawuleza nangokunzima kunesiqhelo.
Uvavanyo loxinzelelo lomzimba lubandakanya ukunika intliziyo yakho inani elincinci "lomthambo" okanye "uxinzelelo" kwindawo elawulwayo nekhuselekileyo uze ujonge indlela esabela ngayo. Oku kunokunceda ugqirha wakho afunde izinto ezibaluleke kakhulu.
- Intliziyo yakho ikwazi kangakanani ukupompa igazi? - Ungabona ukuba amandla okupompa entliziyo yakho ayancipha okanye ayanda xa uzilolonga.
- Ngaba izihlunu zentliziyo zifumana igazi elaneleyo? - Ukuba imithambo yegazi ehambisa igazi entliziyweni (imithambo yegazi ye-coronary) inciphile okanye ivalekile, intliziyo isenokungafumani igazi elaneleyo ngexesha lokuzilolonga. Olu vavanyo lunokukufumanisa oku.
- Ngaba iimpawu zakho zinxulumene nentliziyo? - Ungajonga ukuba iintlungu esifubeni sakho, ukuphefumla kancinci, okanye isiyezi ziyenzeka na ngexesha lokuzilolonga. Ukuba kunjalo, isenokuba yingxaki yentliziyo.
- Injani imisebenzi yombane yentliziyo? - Ungajonga ukuba ukubetha kwentliziyo kuba yinto engaqhelekanga okanye akunjalo xa uzilolonga.
Ngamafutshane, oku kufana "novavanyo lokuqina komzimba" lwentliziyo yakho.
Ngubani ofuna ukwenza olu vavanyo?
Kukho izizathu ezahlukeneyo zokuba ugqirha angakucebisa olu vavanyo. Makhe sijonge ukuba zeziphi.
| Isizathu | Inkcazo |
|---|---|
| Ukuba neempawu zentliziyo | Ukuba ufumana iintlungu esifubeni okanye ukuxinana (okukwabizwa ngokuba yi-angina ) xa uzilolonga, ubunzima bokuphefumla, ukubetha kwentliziyo okukhawulezayo okanye okungahambelaniyo ( i-arrhythmia ), okanye isiyezi, olu vavanyo lunokukunceda ufumane unobangela wezo mpawu. |
| Ukuba semngciphekweni wesifo sentliziyo | Ukuba unesifo seswekile, uxinzelelo lwegazi oluphezulu, i-cholesterol ephezulu, uyatshaya, okanye ukuba umntu kusapho lwakho ukhe waba nesifo sentliziyo esemncinci, nawe usengozini yokuba nesifo sentliziyo. Oku kunokukunceda ufumanise ingxaki ngaphambi kokuba kuvele iimpawu. |
| Ukulinganisa impumelelo yonyango | Ukuba sele ufumana unyango lwesifo sentliziyo (ezifana namayeza, ukufakwa kwe-stent, utyando lwe-bypass), olu vavanyo lwenziwa ukuze kubonwe ukuba unyango lusebenza kangakanani na kwaye nokuba ukusebenza kwentliziyo yakho kuphucukile na. |
| Ngaphambi kokuba uqale inkqubo yokuzilolonga | Ingakumbi ukuba umntu onesifo sentliziyo uqala ukwenza umthambo okokuqala, ulwazi olufunyenwe kolu vavanyo lubalulekile ekumiseleni ukuba loluphi uhlobo lomthambo olufanelekileyo kuye kwaye banokwenza ixesha elingakanani. |
| Ukujonga ukuba intliziyo iphilile na ngaphambi kotyando | Olu vavanyo lukwasetyenziselwa ukuvavanya ukuba intliziyo yakho inamandla ngokwaneleyo na ukumelana noxinzelelo lotyando olungelulo olwentliziyo ngaphambi kokuba wenze utyando olukhulu. |
Kukho iintlobo ezahlukeneyo zovavanyo loxinzelelo.
Ayingabo bonke abantu abavavanywa ngendlela efanayo. Uhlobo lovavanyo olufumanayo lunokwahluka ngokuxhomekeke kwimeko yakho, iimpawu, kunye nolwazi olufunekayo kugqirha wakho.
1. Uvavanyo loxinzelelo lomzimba
Olu lolona hlobo luqhelekileyo nolusisiseko. Okwenzekayo apha kukuba izitikha ezincinci (ii-electrode) zinamathele esifubeni nasezingalweni zakho, kwaye ziqhagamshelwe kumatshini we-`EKG` (i-Electrocardiogram). Emva koko ucelwa ukuba uhambe nge-treadmill okanye ukhwele ibhayisekile engashukumiyo. Isantya kunye nokuthambeka kwe-treadmill (njengokunyuka intaba) kuyandiswa kancinci kancinci. Ngeli xesha, umatshini we-`EKG` uyaqhubeka nokurekhoda umsebenzi wombane wentliziyo yakho. Ukwalinganisa uxinzelelo lwegazi lakho rhoqo.
2. I-Echocardiogram yoxinzelelo lomzimba
Olu luvavanyo oluneenkcukacha ezingaphezulu kancinci kunolwangaphambili. Lubandakanya ukwenza i-'Echocardiogram' (i-ultrasound scan yentliziyo) yentliziyo yakho ngaphambi nasemva kokuba uzilolonge ngokupheleleyo.
Ngamafutshane, 'i-echo' ingayibona ngokubonakalayo indlela izihlunu zentliziyo ezincipha ngayo, indlela ezisebenza ngayo iivalvu, kunye nendlela igazi elihamba ngayo. Ukuba inxalenye yentliziyo ayifumani gazi ngexesha lokuzilolonga, ukuncipha kwezihlunu kuloo nxalenye kuba buthathaka. Oku kunokubonwa ngokucacileyo ngolu vavanyo.
Olu vavanyo luluncedo kakhulu kwiimeko apho iziphumo ze-EKG eqhelekileyo zingacacanga.
3. Uvavanyo loxinzelelo lwenyukliya
Eli gama lisenokuvakala liyoyikisa kancinci, kodwa lisebenzisa into ekhuselekileyo kakhulu, enemitha engaphantsi. Le nto ifakwa emthanjeni wakho. Emva koko, ikhamera ekhethekileyo (i-SPECT okanye i-PET scan) ithatha imifanekiso yegazi elihamba entliziyweni yakho ngelixa uphumle.
Okulandelayo, uzilolonga kwi-treadmill. Emva kokuba ugqibile ukuzilolonga, ikhamera ithatha imifanekiso kwakhona. Ngoku ugqirha angathelekisa imifanekiso ethathwe ngexesha lokuphumla nemifanekiso ethathwe emva kokuzilolonga. Ukuba umthambo wegazi uvaliwe, ukuhanjiswa kwegazi kwinxalenye yemisipha yentliziyo enikezelwa ngulo mthambo kuncipha ngexesha lokuzilolonga. Oku kunokubonakala ngokucacileyo kwimifanekiso. Oku kunokunika uvavanyo oluchanekileyo lobunzima bokuvaleka kwemithambo yentliziyo.
Ufanele uzilungiselele njani ngaphambi kovavanyo?
Ukuze ufumane iziphumo ezichanekileyo, kubaluleke kakhulu ukuba ulungiselele kakuhle ngaphambi kovavanyo.
- Ukutya Nesiselo: Musa ukutya okanye ukusela nantoni na kangangeeyure ezimbalwa ngaphambi kovavanyo. Kulungile ukusela amanzi amancinci. Ingakumbi ukuba wenza uvavanyo lwe-'Nuclear Stress Test', ungacelwa ukuba uzile ukutya de uvavanyo luphele.
- Ziphephe i-caffeine:Musa ukutya nantoni na equlethe i-caffeine, efana nekofu, iti, itshokolethi, okanye ezinye iziselo ezinika amandla, kangangeeyure ezingama-24 ngaphambi kovavanyo. I-caffeine inokutshintsha izinga lentliziyo yakho kwaye inokuchaphazela iziphumo.
- Kuphephe ukutshaya: Musa ukutshaya ngomhla wovavanyo.
- Buza ugqirha wakho ngamayeza: Ugqirha wakho angakucela ukuba uyeke ukusebenzisa amayeza athile owasebenzisa rhoqo (umzekelo, amayeza entliziyo afana ne-beta-blockers, ezinye ii-inhalers ze-asthma) ngomhla wovavanyo. Ungaze uyeke ukuthatha amayeza wedwa. Soloko uthetha nogqirha wakho kwaye ulandele imiyalelo yakhe ngokuchanekileyo.
- Kubantu abanesifo seswekile: Ukuba usela amayeza eswekile, ukuzila ukutya kunokuba yingxaki. Ngoko ke, thetha nogqirha wakho weswekile ngaphambi kovavanyo ukuze ufumane ingcebiso malunga nendlela yokusela amayeza akho nokutya ngaloo mini. Ukuba une-glucose monitor, yiza nayo.
- Impahla: Nxiba impahla elula nekhululekileyo kunye nezihlangu zokuhamba ezikhululekileyo (ezifana nezihlangu ze-canvas okanye izihlangu zemidlalo).
- Hlala uzolile: Kuqhelekile ukuba novalo kancinci xa uza kuvavanya. Kodwa ukuba unovalo kakhulu, izinto ezifana nokubetha kwentliziyo yakho kunye noxinzelelo lwegazi zinokutshintsha kwaye zichaphazele iziphumo. Ngoko zama ukuhlala uzolile kangangoko unako.
Kwenzeka ntoni ngexesha lovavanyo?
Xa usiya kwilebhu, umongikazi okanye ingcali iya kuqala ilinganise kwaye irekhode uxinzelelo lwakho lwegazi oluphumlayo kunye nesantya sentliziyo yakho. Emva koko baya kuncamathisela ii-electrodes esifubeni sakho nasezingalweni zakho eziya kudibana ne-EKG.
Okulandelayo, uza kucelwa ukuba ukhwele i-treadmill. Iqala kancinci, njengokuhamba emhlabeni othe tyaba. Rhoqo ngemizuzu embalwa, igosa eliphetheyo liya kunyusa isantya kunye nokuthambeka kwe-treadmill. Rhoqo, baza kukubuza, "Uziva njani?" "Ingaba unengxaki?" Ukuba uziva ungakhululekanga, iintlungu zesifuba, okanye isiyezi, kufuneka ubaxelele ngoko nangoko.
Wakuba ufikelele kwinqanaba lentliziyo ekujoliswe kulo elichongiweyo ngokusekwe kubudala bakho kunye nenqanaba lokomelela komzimba, uya kugcina elo nqanaba imizuzu embalwa uze uyeke uvavanyo. Icandelo lokuzilolonga lidla ngokuthatha malunga nemizuzu eli-10-15. Nangona kunjalo, ukuba ubonakalisa iimpawu ezinzima ngaphambi kwelo xesha okanye ukuba uthi awukwazi ukuqhubeka nalo, uvavanyo luya kuyekiswa kwangethuba.
Ulwenza njani uvavanyo kumntu ongakwaziyo ukuzilolonga?
Khawucinge ukuba umntu akakwazi ukuhamba kwi-treadmill ngenxa yokwenzakala kwamalungu okanye esinye isizathu. Kwanabantu abanjalo banokwenza olu vavanyo. Ngelo xesha, ulaliswa ebhedini kwaye iyeza lifakwa emthanjeni. Eli yeza lenza intliziyo yakho ibethe ngokukhawuleza, njengaxa uzilolonga. Ngale ndlela, intliziyo inikwa "amandla" (uxinzelelo) ngokwenziwa.
Emva kokuba uvavanyo lugqityiwe, baza kukujonga kangangemizuzu eli-15 de isantya sentliziyo yakho kunye noxinzelelo lwegazi zibuyele esiqhelweni. Nje ukuba yonke into iqhelekile, ungagoduka.
Zithini iziphumo zovavanyo?
Wakuba ufumene ingxelo yovavanyo, ugqirha wakho uza kuyihlalutya aze akuchazele yona. Iziphumo zingahlulwa zibe ziinxalenye ezimbini eziphambili.
Ukuba iziphumo ziqhelekile...

- Ukuba uvavanyo lwenziwe ukuze kufunyanwe unobangela weempawu zakho: Iintlungu zesifuba sakho zinokubangelwa yinto ethile, efana noxinzelelo okanye isifo sesisu. Ugqirha wakho uya kuyalela ezinye iimvavanyo ukuze afumanise.
- Ukuba yenziwe ngaphambi kokuzilolonga okanye utyando: Oku kuthetha ukuba intliziyo yakho inamandla ngokwaneleyo ukuqala inkqubo yokuzilolonga okanye ukwenza utyando.
Ukuba iziphumo aziqhelekanga...
Isiphumo esingaqhelekanga sithetha ukuba intliziyo yakho ibe nengxaki ngexesha lokuzilolonga, nto leyo enokuba luphawu lwesifo sentliziyo.
- Utshintsho kwi-EKG: Xa kungekho ukuhamba kwegazi okwaneleyo entliziyweni (ischemia), i-EKG ibonisa utshintsho oluthile.
- Intlungu yesifuba: Ukuba ufumana iintlungu zesifuba ngelixa uzilolonga, oko kungaba luphawu lokuba umthambo wentliziyo uvalekile.
- Uxinzelelo lwegazi olungaqhelekanga: Uxinzelelo lwegazi olunganyukiyo okanye olungawi kakuhle ngexesha lokuzilolonga nalo lunokuba yingxaki.
Eyona nto ibalulekileyo kukuba, ungoyiki ngenxa yesiphumo esingaqhelekanga. Akuthethi ukuba uza kuba nesifo sentliziyo. Kuthetha nje ukuba kukho ingxaki entliziyweni yakho ekufuneka siyiqwalasele size sithathe amanyathelo afunekayo.
Ukuba kufunyenwe iziphumo ezingaqhelekanga, ugqirha uya kugqiba ukuba enze ntoni emva koko.
- Utshintsho oluncinci luquka: utshintsho kwindlela yokuphila (ukuyeka ukutshaya, ulawulo lokutya, umthambo) kunye namayeza okulawula i-cholesterol kunye noxinzelelo lwegazi.
- Utshintsho olukhulu lulandelayo:Ezinye iimvavanyo zingayalelwa ukuqinisekisa ngakumbi ingxaki kwaye zibone ngqo apho ukuvaleka kukhoyo. Umzekelo, ungathunyelwa kwinto efana ne-'CT Coronary Angiography' (i-CT scan) okanye i-'Cardiac Catheterization' (uvavanyo lwe-angiogram).
Umyalezo Wokuya Ekhaya
- Uvavanyo loxinzelelo lokuzilolonga alufanele luyoyike. Luvavanyo olukhuselekileyo noluqhelekileyo lokujonga impilo yentliziyo yakho.
