Cinga ngentliziyo yakho njengempompo yamanzi. Umsebenzi wayo ophambili kukupompa igazi emzimbeni wonke. Ngoko ke, uvavanyo olukhethekileyo olulinganisa ukusebenza kakuhle kokupompa, oko kukuthi, indlela intliziyo esebenza kakuhle ngayo, lubizwa ngokuba yi-MUGA scan. Eli gama lisenokuba litsha kuwe. Ngoko ke namhlanje, masithethe ngalo ngokulula, ngendlela onokuyiqonda.
Yintoni i-MUGA scan?
Ngamafutshane, i-MUGA scan luvavanyo olukhethekileyo lokujonga oluvavanya, okanye olulinganisa ngokuchanekileyo, ukuba intliziyo yakho ipompa igazi kangakanani na. Lubandakanya ukufaka isixa esincinci kakhulu sento enemisebe ebizwa ngokuba yi-"radionuclide" kwenye yemithambo yakho. Emva koko, kusetyenziswa ikhamera ekhethekileyo, imifanekiso yentliziyo yakho ithathwa njengoko esi sithako sihamba entliziyweni yakho ngegazi lakho.
Olu vavanyo lunokukunika umfanekiso ocacileyo wendlela izihlunu zentliziyo yakho ezifinyela ngayo kwaye ziphumla ngayo xa uphumle nangexesha lokuzilolonga. Amanye amagama olu vavanyo yi-'radionuclide ventriculography (RNVG)` kunye ne-`equilibrium radionuclide angiocardiography (ERNA)`.
Yintoni kanye kanye le scan eboniswayo?
Eyona nto iphambili le nto ilinganiswa yi -Ejection Fraction (EF) yakho. Ngoku usenokuba uyazibuza ukuba ithetha ukuthini i-EF.
Khawuthelekelele intliziyo yakho izaliswe ligazi, ize ifinyeze (icinezele) ize ipompe elo gazi emzimbeni. Oko sikubiza ngokuba yi-EF yipesenti yenani lilonke legazi entliziyweni elikhutshwayo ngexesha lokufinyeza kwegazi.
Umzekelo, ukuba i-EF yakho yi-70%, oko kuthetha ukuba xa intliziyo yakho izele ligazi kwaye ikhupha kanye, ikhupha i-70% yomthamo wegazi uphela emzimbeni. I-EF eqhelekileyo yomntu ophilileyo iphakathi kwe-50% kunye ne-75%.
Kufuneka nini i-MUGA scan?
Ugqirha wakho angacebisa olu vavanyo ukuba uneempawu zokusilela kwentliziyo. Ukusilela kwentliziyo kuxa intliziyo ingakwazi ukupompa igazi ngokufanelekileyo. Le theyibhile ingezantsi idwelisa ezinye zeempawu eziqhelekileyo ezinokubakho ngeli xesha.
| Uphawu | Ingcaciso elula |
|---|---|
| Intlungu yesifuba (i-Angina) | Intlungu yokucinezelwa eyenzeka xa intliziyo ingafumani ioksijini eyaneleyo. |
| Isiyezi | Ingabangelwa kukuncipha kokuhamba kwegazi ukuya engqondweni. |
| Ndiziva ndidiniwe ngokukhawuleza | Uhlala uziva udiniwe kuba iiseli zomzimba wakho azifumani ioksijini kunye nezondlo ezizidingayo. |
| Ubunzima bokuphefumla (i-Dyspnea) | Ukuqokelelana kolwelo emiphungeni kwenza kube nzima ukuphefumla nokuba kukho imisebenzi emincinci. |
| Ukudumba kwezandla okanye iinyawo (i-Edema) | Ukuqokelelana kolwelo kwizicubu zomzimba kubangela ukudumba, ingakumbi emilenzeni nasemaqatheni. |
Kwakhona, ugqirha wakho unokuyalela olu vavanyo ngaphambi okanye emva kwezinye iindlela zonyango lomhlaza. Oku kungenxa yokuba ezinye iindlela zonyango lomhlaza zingonakalisa intliziyo. Ezinye zezi ndlela zonyango ziquka:
- Ukufakelwa komongo wethambo
- Unyango ngamakhemikhali
- Unyango lwe-immunotherapy
- Unyango lwemitha esifubeni
Yintoni umahluko phakathi kwe-MUGA scan kunye ne-Echo test?
Zombini ezi mvavanyo zibonelela ngolwazi lwemifanekiso malunga nokusebenza kwentliziyo, kodwa iindlela zahlukile.
- I-Echocardiogram: Olu vavanyo lusebenzisa amaza esandi, afana ne-ultrasound scan yomntwana womfazi okhulelweyo. Imifanekiso ithathwa ngugqirha njengoko ehambisa isixhobo esikhethekileyo (i-transducer) phezu kwesifuba sakho.
- I-MUGA scan: Olu luvavanyo lwe-nuclear imaging. Lusebenzisa i-radioactive tracer.
Eyona nto ibalulekileyo kukuba i-MUGA scan idla ngokubonelela ngexabiso le-EF elichanekileyo ngakumbi kune-Echo test.
Ufanele uzilungiselele njani ngaphambi kovavanyo?
Ugqirha wakho uza kukunika imiyalelo ethile ngaphambi kolu vavanyo. Kubaluleke kakhulu ukulandela loo miyalelo ngokuchanekileyo. Ngokubanzi, le miyalelo iquka:
- Kuphephe ukutya okanye ukusela malunga neeyure ezintandathu ngaphambi kovavanyo.
- Musa ukusebenzisa i-caffeine (ikofu, iti, iziselo ezibandayo) kangangeeyure ezimbalwa, kuba i-caffeine inokunyusa izinga lentliziyo yakho kwaye ichaphazele iziphumo zovavanyo.
- Xelela ugqirha wakho ngazo zonke amayeza owasebenzisayo . Amanye amayeza entliziyo (afana ne-nitrate okanye i-digoxin) anokufuneka amiswe ngosuku okanye ezimbini ngaphambi kovavanyo.
Kwenzeka ntoni ngexesha lovavanyo?
Yonke le nkqubo ingathatha naphi na ukusuka kwiyure enye ukuya kwezintathu. Ngeli xesha, uza kulala phantsi etafileni yovavanyo kwaye ikhamera ekhethekileyo iya kubekwa phezu kwesifuba sakho. Emva koko, ingcali iza kulandela la manyathelo:
1. Ii-electrode ezininzi (izitikha ezifana nezo zisetyenziselwa i-ECG) ziya kubekwa esifubeni sakho. Ezi ziya kulinganisa umsebenzi wombane wentliziyo yakho.
2. Le nto irhabaxa ekhankanyiweyo ngaphambili ``(radiotracer)`` ifakwa kwenye yemithambo yakho.
3. Ikhamera ithatha imifanekiso yentliziyo yakho kwiikona ezahlukeneyo.
Ngamanye amaxesha, uya kucelwa ukuba wenze umthambo ngelixa kuthatyathwa imifanekiso. Umzekelo , ukuhamba kwi-treadmill . Oku kwenzelwa ukubona indlela intliziyo yakho esabela ngayo kuxinzelelo.
Kwenzeka ntoni emva kovavanyo?
Iindaba ezimnandi zezokuba ungaqhubeka nemisebenzi yakho yesiqhelo, kuquka nokuqhuba, kwangoko nje ukuba uvavanyo luphelile. Kodwa khumbula into enye: Sela ulwelo oluninzi, kuquka namanzi , usuku olunye okanye ezimbini emva kovavanyo. Oku kuya kunceda izinto ezinemisebe ziphume emzimbeni wakho ngokukhawuleza.
Ngaba kukho umngcipheko kule nto?
I-MUGA scan luvavanyo olukhuselekileyo kubantu abaninzi. Ubungakanani bezinto ezine-radioactive ezifakwe kwi-infusion buncinci kakhulu, ngoko ke abunabungozi. Kwaye ngokuqhelekileyo isuswa ngokupheleleyo emzimbeni kwiiyure ezingama-24.
Nangona kunjalo, ukuba ukhulelwe, ucinga ukuba ukhulelwe, okanye uncancisa, ngokuqinisekileyo kufuneka uxelele ugqirha wakho ngale nto , kuba olu vavanyo alusoloko lucetyiswa kwiimeko ezinjalo.
Izinto onokuzibuza ugqirha wakho
Ukuba uneminye imibuzo malunga nolu vavanyo, ungoyiki ukubuza ugqirha wakho. Ungabuza izinto ezinje:
- Kutheni ndifuna i-MUGA scan?
- Olu vavanyo luthatha ixesha elingakanani?
- Ngaba kukho into ekufuneka ndiyenze ngokukodwa ukuze ndilungiselele uvavanyo?
- Zithini iingenelo zolu vavanyo?
- Ingxelo yophando ithini?
- Ngawaphi amanyathelo am alandelayo emva kolu vavanyo?
Umyalezo Wokuya Ekhaya
- I-MUGA scan luvavanyo oluchanekileyo kakhulu lokulinganisa ukusebenza kakuhle kwentliziyo yakho ekupompeni igazi (EF).
- Isetyenziselwa ukuxilonga izifo ezifana nesifo sentliziyo kunye nokujonga impilo yentliziyo ngexesha lonyango lomhlaza.
- Kule nto, kufakwa inani elincinci kakhulu lezinto ezinemisebe emzimbeni, nto leyo engenabungozi kwaye ikhutshwa emzimbeni kungekapheli nosuku.
- Ukuba ukhulelwe, uncancisa, okanye usela naluphi na olunye unyango, qiniseka ukuba wazise ugqirha wakho ngaphambi kovavanyo.
- Ugqirha wakho uza kukuchazela iziphumo zovavanyo kunye namanyathelo oza kuwathatha kwixesha elizayo.
