Cabanga ngenhliziyo yakho njengephampu yamanzi. Umsebenzi wayo oyinhloko ukupompa igazi emzimbeni wonke. Ngakho-ke, ukuhlolwa okukhethekile okulinganisa ukusebenza kahle kokupompa, okungukuthi, ukuthi inhliziyo isebenza kahle kangakanani, kubizwa ngokuthi i-MUGA scan. Leli gama lingase libe lisha kuwe. Ngakho-ke namuhla, ake sixoxe ngalo kalula, ngendlela ongayiqonda.
Kuyini ukuskena kwe-MUGA?
Kalula nje, i-MUGA scan iyisivivinyo esikhethekile sokuhlola esihlola, noma esilinganisa ngokunembile, ukuthi inhliziyo yakho ipompa igazi kahle kangakanani. Kuhilela ukufaka inani elincane kakhulu lento ekhipha imisebe ebizwa ngokuthi ``i-radionuclide'' komunye wemithambo yakho. Bese kuthi, kusetshenziswa ikhamera ekhethekile, kuthathwe izithombe zenhliziyo yakho njengoba lesi sici sihamba enhliziyweni yakho negazi lakho.
Lokhu kuhlolwa kungakunikeza isithombe esicacile sokuthi imisipha yenhliziyo yakho ifinyela futhi iphumule kanjani uma uphumule nangesikhathi sokuzivocavoca. Amanye amagama alolu vivinyo yi-'radionuclide ventriculography (RNVG)' kanye ne-'equilibrium radionuclide angiocardiography (ERNA)'.
Yini ngempela eboniswa yilesi skeni?
Into eyinhloko lokhu okukalayo yi -Ejection Fraction (EF) yakho. Manje ungase uzibuze ukuthi kusho ukuthini i-EF.
Cabanga ngenhliziyo yakho igcwala igazi, bese lifinyela (licindezela) bese likhipha lelo gazi emzimbeni. Lokho esikubiza ngokuthi i-EF yiphesenti yenani eliphelele legazi enhliziyweni elikhishwa ngesikhathi sokufinyela ngakunye.
Isibonelo, uma i-EF yakho ingu-70%, kusho ukuthi uma inhliziyo yakho igcwele igazi futhi iphampa kanye, iphampa u-70% womthamo wegazi ophelele emzimbeni. I-EF evamile yomuntu ophilile iphakathi kuka-50% no-75%.
Kudingeka nini ukuskena kwe-MUGA?
Udokotela wakho angase akuncome lokhu kuhlolwa uma unezimpawu zokwehluleka kwenhliziyo. Ukwehluleka kwenhliziyo yilapho inhliziyo ingakwazi ukupompa igazi kahle. Ithebula elingezansi libala ezinye zezimpawu ezivamile ezingavela phakathi nalesi sikhathi.
| Isibonakaliso | Incazelo elula |
|---|---|
| Ubuhlungu besifuba (i-Angina) | Ubuhlungu obucindezelayo obuvela lapho inhliziyo ingatholi umoya-mpilo owanele. |
| Isiyezi | Kungabangelwa ukwehla kokugeleza kwegazi kuya ebuchosheni. |
| Ukuzizwa ukhathele ngokushesha | Uzizwa ukhathele ngaso sonke isikhathi ngoba amangqamuzana omzimba wakho awatholi umoya-mpilo nezakhamzimba azidingayo. |
| Ubunzima bokuphefumula (i-Dyspnea) | Ukuqongelela koketshezi emaphashini kwenza kube nzima ukuphefumula ngisho nangemisebenzi emincane. |
| Ukuvuvukala kwezandla noma izinyawo (i-Edema) | Ukuqongelela koketshezi ezicutshini zomzimba kubangela ukuvuvukala, ikakhulukazi emilenzeni nasemaqakaleni. |
Futhi, udokotela wakho angase akucele lokhu kuhlolwa ngaphambi noma ngemva kokwelashwa komdlavuza. Lokhu kungenxa yokuthi okunye ukwelashwa komdlavuza kungalimaza inhliziyo. Ezinye zalezi zindlela zokwelapha zifaka:
- Ukufakelwa umnkantsha wethambo
- Ukwelashwa ngamakhemikhali
- Ukwelashwa nge-immunotherapy
- Ukwelashwa ngemisebe esifubeni
Uyini umehluko phakathi kwe-MUGA scan kanye ne-Echo test?
Zombili lezi zivivinyo zinikeza ulwazi lwezithombe mayelana nokusebenza kwenhliziyo, kodwa izindlela zihlukile.
- I-Echocardiogram: Lokhu kuhlolwa kusebenzisa amaza omsindo, afana nokuskena kwe-ultrasound kwengane yowesifazane okhulelwe. Izithombe zithathwa udokotela njengoba ehambisa idivayisi ekhethekile (i-transducer) phezu kwesifuba sakho.
- I-MUGA scan: Lokhu ukuhlolwa kwesithombe senuzi. Kusebenzisa i-radioactive tracer.
Into ebaluleke kakhulu ukuthi ukuskena kwe-MUGA kunganikeza inani le-EF elinembile kakhulu kunesivivinyo se-Echo.
Kufanele uzilungiselele kanjani ngaphambi kokuhlolwa?
Udokotela wakho uzokunikeza imiyalelo eqondile ngaphambi kwalokhu kuhlolwa. Kubaluleke kakhulu ukulandela leyo miyalelo ngqo. Ngokuvamile, lokhu kufaka phakathi:
- Gwema ukudla noma ukuphuza cishe amahora ayisithupha ngaphambi kokuhlolwa.
- Gwema i-caffeine (ikhofi, itiye, iziphuzo ezibandayo) amahora ambalwa ngaphambi kokuhlolwa, ngoba i-caffeine ingakhuphula izinga lokushaya kwenhliziyo yakho futhi ithinte imiphumela yokuhlolwa.
- Tshela udokotela wakho ngayo yonke imithi oyiphuzayo . Eminye imithi yenhliziyo (njenge-nitrate noma i-digoxin) kungadingeka iyekwe usuku noma ezimbili ngaphambi kokuhlolwa.
Kwenzekani ngesikhathi sokuhlolwa?
Yonke inqubo ingathatha noma yikuphi kusukela ehoreni elilodwa kuya kwamathathu. Phakathi nalesi sikhathi, uzolala etafuleni lokuhlolwa bese kubekwa ikhamera ekhethekile esifubeni sakho. Ngemuva kwalokho, uchwepheshe uzolandela lezi zinyathelo:
1. Ama-electrode amaningana (izitikha ezifana nalezo ezisetshenziswa ku-ECG) azobekwa esifubeni sakho. Lawa azolinganisa umsebenzi kagesi wenhliziyo yakho.
2. Into ekhipha imisebe eshiwo ngaphambilini ethi ``(radiotracer)`` ifakwa komunye wemithambo yakho.
3. Ikhamera ithatha izithombe zenhliziyo yakho ngezindlela ezahlukene.
Ngezinye izikhathi, uzocelwa ukuthi wenze ukuzivocavoca ngenkathi kuthwetshulwa izithombe. Isibonelo , ukuhamba nge-treadmill . Lokhu kwenzelwa ukubona ukuthi inhliziyo yakho isabela kanjani ekucindezelekeni.
Kwenzekani ngemva kokuhlolwa?
Izindaba ezinhle ukuthi ungaqhubeka nemisebenzi yakho evamile, okuhlanganisa nokushayela, ngokushesha nje lapho isivivinyo sesiphelile. Kodwa khumbula into eyodwa: Phuza uketshezi oluningi, okuhlanganisa namanzi , usuku olulodwa noma ezimbili ngemva kwesivivinyo. Lokhu kuzosiza izinto ezikhipha imisebe ziphume emzimbeni wakho ngokushesha.
Ingabe kukhona ingozi kulokhu?
I-MUGA scan iyisivivinyo esiphephile kakhulu kubantu abaningi. Inani lezinto ezikhipha imisebe ezifakwe lincane kakhulu, ngakho alilimazi. Futhi ngokuvamile likhishwa ngokuphelele emzimbeni zingakapheli amahora angama-24.
Kodwa-ke, uma ukhulelwe, ucabanga ukuthi ukhulelwe, noma uncelisa, kufanele utshele udokotela wakho ngalokhu , njengoba lokhu kuhlolwa ngokuvamile kunganconywa ezimweni ezinjalo.
Izinto okufanele uzibuze udokotela wakho
Uma uneminye imibuzo mayelana nalolu vivinyo, ungesabi ukubuza udokotela wakho. Ungabuza izinto ezifana nalezi:
- Kungani ngidinga i-MUGA scan?
- Kuthatha isikhathi esingakanani lokhu kuhlolwa?
- Ingabe kukhona okudingeka ngikwenze ngqo ukuze ngilungiselele ukuhlolwa?
- Yiziphi izinzuzo zalolu vivinyo?
- Uthini umbiko wophenyo?
- Yiziphi izinyathelo zami ezilandelayo ngemva kwalolu vivinyo?
Umlayezo Wokuya Nawe Ekhaya
- I-MUGA scan iyisivivinyo sokuthwebula izithombe esinembile kakhulu esilinganisa ukusebenza kahle kokupompa igazi kwenhliziyo yakho (i-EF).
- Isetshenziselwa ukuxilonga izimo ezifana nesifo senhliziyo nokuqapha impilo yenhliziyo ngesikhathi sokwelashwa komdlavuza.
- Kulokhu, inani elincane kakhulu lezinto ezinemisebe lifakwa emzimbeni, okuyinto engenangozi futhi ekhishwa emzimbeni phakathi nosuku.
- Uma ukhulelwe, uncelisa, noma uphuza eminye imithi, qiniseka ukuthi wazisa udokotela wakho ngaphambi kokuhlolwa.
- Udokotela wakho uzochaza imiphumela yokuhlolwa kanye nanoma yiziphi izinyathelo zesikhathi esizayo okudingeka uzithathe.
