Wake wazibuza ukuthi kwenzekani ezinhliziyweni zethu lapho sizivocavoca, sigijima, noma sikhuphuka izitebhisi? Ngaleso sikhathi, inhliziyo idinga umoya-mpilo omningi kunalokho obekuvame ukwenzeka. Ukuze kuhlangatshezwane nalesi sidingo esikhulu somoya-mpilo, inani legazi eligeleza ngemithambo yenhliziyo enikeza igazi enhliziyweni ngokwayo nalo kudingeka lande. Ngakho-ke, ikhono lenhliziyo yakho lokwandisa ukugeleza kwegazi lapho isidingo sanda libizwa ngokuthi i-Coronary Flow Reserve (CFR). Lokhu kufana 'namandla okugcina' enhliziyo yakho.
Kuyini i-Coronary Flow Reserve (CFR)?
Kalula nje, i-Coronary Flow Reserve (CFR) iyisilinganiso sokuthi igazi elingakanani elingageleza ngemithambo yenhliziyo yakho ngesikhathi sokuzikhandla okukhulu. Lokhu kunganikeza udokotela wakho ulwazi olubalulekile mayelana nempilo yenhliziyo yakho, ikakhulukazi isimo semithambo enikeza igazi enhliziyweni yakho (imithambo yenhliziyo).
Cabanga ngalokhu. Uma uhleli esihlalweni, inhliziyo yakho idinga inani elithile legazi. Kodwa uma ugijima ngokuzumayo ulandela ibhasi, umsebenzi wenhliziyo yakho uyanda kakhulu. Inhliziyo yakho idinga umoya-mpilo ophindwe kathathu kuya kane kunokuvamile. Imithambo yegazi yenhliziyo enempilo ingabhekana nalesi sidingo esikhulayo, ikhulise ukugeleza kwegazi ngokushesha. Ukuhlolwa kwe-CFR kulinganisa ikhono lenhliziyo yakho lokwenza lokhu.
Lokhu kuhlolwa kusiza ekutholeni kusenesikhathi ukuthi unesifo semithambo yenhliziyo noma usengozini yokuthola isimo esifana nokuhlaselwa yinhliziyo esikhathini esizayo.
Ibalwa kanjani inani le-CFR?
Indlela lokhu okubalwa ngayo ilula kakhulu. Udokotela wakho ulinganisa ukugeleza kwegazi enhliziyweni yakho ngezindlela ezimbili.
1. Ukugeleza kwegazi ngesikhathi sokuphumula: Lokhu kulinganisa inani legazi eligeleza enhliziyweni uma uphumule, ngaphandle kokuzikhandla.
2. Ukugeleza kwegazi okuphezulu: Inhliziyo iphoqeleka ukupompa igazi ngomzamo omkhulu (kunikezwa umuthi walokhu), bese kulinganiswa inani eliphezulu legazi eligeleza ngaleso sikhathi.
Ngemuva kwalokho, lokhu kugeleza kwegazi okuphezulu kuhlukaniswa ngokugeleza kwegazi okuphumulile.
I-CFR = (Ukugeleza Kwegazi Okuphezulu) / (Ukugeleza Kwegazi Okuphumuzayo)
Isibonelo, uma ukugeleza kwegazi okuphezulu kwakho kuphindwe kathathu ukugeleza kwegazi kwakho kokuphumula, inani lakho le-CFR lizoba ngu-3.
Iyini inani elimaphakathi le-CFR?
I-CFR yomuntu ophilile kufanele ibe phakathi kuka-2.0 no-2.5 . Lokhu kusho ukuthi inhliziyo kufanele ikwazi ukupompa okungenani igazi eliphindwe kabili kunalelo engalimpompa uma iphumule. Kumuntu ophilile kakhulu, leli nani lingaba ngu-3, 4, noma ngaphezulu.
- Uma inani le-CFR lingaphansi kuka-2.0:Lokhu kusho ukuthi kungase kube nenkinga ethile ngemithambo yegazi enhliziyweni. Mhlawumbe imithambo yegazi inciphile (ivinjiwe). Abantu abanjengalaba basengozini enkulu yokuthola isifo senhliziyo esikhathini esizayo.
- Uma inani le-CFR lingaphezu kuka-2.0: Libonisa ukuthi ukusebenza kwemithambo yegazi enhliziyweni kusezingeni elihle.
Kodwa into eyodwa okufanele uyikhumbule ukuthi leli nani le-CFR liyancipha ngokwemvelo ngokuguga. Ngakho-ke, inani elijwayelekile lomuntu osemusha lingase lihluke kunenani elijwayelekile lomuntu omdala. Udokotela wakho kuphela ongachaza imiphumela yakho ngokunembile.
Ungenza kanjani ukuhlolwa kwe-CFR?
Kunezindlela ezimbili eziyinhloko zokwenza lokhu kuhlolwa: enye iyindlela yokuhlasela, ehilela ukufaka idivayisi emzimbeni, kanti enye iyindlela yangaphandle, ehilela ukuyenza ngaphandle kokuhlasela.
| Indlela yokuhlola | Incazelo elula |
|---|---|
| Okungenayo - Ukufakwa Kwe-Catheterization Yenhliziyo | Kulokhu, ipayipi elincane kakhulu (i-catheter) lidluliselwa ngomthambo ongalweni yakho, emlenzeni, noma entanyeni liye emithanjeni yenhliziyo yakho. Kube sekudluliselwa ucingo olukhethekile ukuze kulinganiswe isivinini sokugeleza kwegazi. Lokhu kungenziwa ngesikhathi esifanayo ne-angiogram. |
| Indlela engahlaseli - I-PET Scan | Lokhu ukuskena okukhethekile. Kulokhu kuhlolwa, unikezwa inani elincane kakhulu lento enemisebe (i-radiotracer) nge-IV. Ngemuva kwalokho, isithwebuli se-PET silinganisa ukugeleza kwegazi ngokubheka ukuthi into ihamba kanjani enhliziyweni. |
| Ezinye izindlela - I-MRI Yenhliziyo | Lokhu futhi kuyiskeni yangaphandle, kodwa le ndlela ayisetshenziswa kakhulu ukukala i-CFR. |
Kufanele uzilungiselele kanjani ngaphambi kokuhlolwa?
Udokotela wakho uzochaza lokhu kuwe. Ngokuvamile, kufanele uqaphele ngalezi zinto.
- Ulwazi Lwemithi: Tshela udokotela wakho ngayo yonke imithi oyithathayo (kokubili kadokotela kanye nemithi ongayithenga ngaphandle kwemithi kadokotela). Eminye imithi ingathinta ukujiya kwegazi futhi ungase ucelwe ukuthi uyeke ukuyithatha ngosuku olwandulela ukuhlolwa.
- Ukungezwani komzimba: Qiniseka ukuthi uyasitshela uma une-allergy kunoma yimiphi imithi noma idayi yokuqhathanisa.
- Ukuzila Ukudla: Uma uhlolwa nge-catheterization yenhliziyo noma nge-PET scan, uzokwaziswa ukuthi ungadli noma uphuze amahora angu-6-8 ngaphambi kokuhlolwa.
- Uma ufuna i-MRI: Awukwazi ukugqoka noma yiziphi izinto zensimbi (ubucwebe, amawashi) emzimbeni wakho. Uma unedivayisi efana ne-pacemaker emzimbeni wakho, buza udokotela wakho kusenesikhathi ukuthi iphephile yini uma ufuna i-MRI.
Yini ongayilindela ngesikhathi sokuhlolwa?
Kungakhathaliseki ukuthi iyiphi indlela yokuhlola onayo, ithubhu ye-IV (i-cannula) izofakwa engalweni yakho. Izinyathelo zokuhlola zizobukeka kanje.
1. Ukulinganisa isimo sokuphumula: Okokuqala, ukugeleza kwegazi enhliziyweni yakho kulinganiswa ngenkathi uzolile futhi uphumule.
2. Ukunikeza umuthi: Okulandelayo, umuthi (i-vasodilator) okhulisa imithambo yegazi enhliziyweni yakho futhi wandise ukugeleza kwegazi unikezwa nge-IV. Umuthi osetshenziswa kakhulu yi -Adenosine . Uma lokhu kunikezwa, ukugeleza kwegazi enhliziyweni kuyanda izikhathi ezingu-4-5 phakathi nemizuzu engu-2-3.
3. Ukulinganisa Okuphezulu: Lapho ukugeleza kwegazi kufinyelela esicongweni ngemva kokunikezwa umuthi, ukugeleza kwegazi kulinganiswa futhi.
4. Ukuqhathanisa: Okokugcina, lezi zilinganiso ezimbili ziqhathaniswa ukuze kubalwe inani lakho le-CFR.
Uma uhlinzwa nge-catheter yenhliziyo, ungase unikezwe umuthi wokudambisa ukuze ulale kancane. Lokhu kuzokusiza uzizwe ungakhululekile. Uma uskenwa, kubaluleke kakhulu ukuhlala unganyakazi ukuze uthole izithombe ezicacile.
Kwenzekani ngemva kokuhlolwa?
Ngemva kokuhlolwa, ungaphila impilo ejwayelekile, kodwa kudingeka uqaphele ngezinye izinto.
- Uma uke waba ne-catheterization yenhliziyo, kuzodingeka ugcine ingalo noma umlenze lapho i-catheter ifakwe khona uqonde cishe ihora ukuze uvimbele ukuphuma kwegazi.
- Udokotela uzokweluleka ukuthi uphuze amanzi amaningi ukuze usize idayi yokuhlukanisa iphume emzimbeni wakho ngokushesha.
- Uma unikezwe umuthi wokudambisa, awukwazi ukushayela ngalolo suku. Kubalulekile ukuthi othile akuphelezele uye ekhaya.
Ingabe kukhona izingozi noma imiphumela emibi kulokhu kuhlolwa?
Ukuhlolwa kwe-CFR ngokuvamile kuyindlela ephephile kakhulu yokuhlola, kodwa njenganoma yikuphi ukuhlolwa kwezokwelapha, kunezingozi ezincane kakhulu.
- Izingozi ezihlobene ne-catheter:Ngesikhathi sokufakwa kwe-catheter yenhliziyo, amahlule egazi, ukulimala kwemithambo yegazi, noma ukuphuma kwegazi akuvamile ukwenzeka.
- Imiphumela emibi ye-adenosine: Abanye abantu bangase babe nalokhu okulandelayo imizuzwana embalwa ngemva kokunikezwa lo muthi:
- Isigqi senhliziyo esingajwayelekile
- Umfutho wegazi ophakeme
- Ubunzima bokuphefumula
- Ukungakhululeki esifubeni
Lezi zimpawu ziyanyamalala ngokuphelele ngokushesha nje lapho umuthi uphela (ngomzuzu owodwa) . Akukho okufanele ukhathazeke ngakho.
Okubalulekile: I-Adenosine ayifanele abantu abane-asthma ngoba ingabangela i-bronchospasm . Uma une-asthma, udokotela wakho uzosebenzisa omunye umuthi esikhundleni salokho.
Isho ukuthini imiphumela futhi sizokwazi nini?
I-CFR yakho iyinombolo ekutshela ukuthi inhliziyo yakho ingapompa igazi elingakanani uma icindezelekile.
Kungathatha izinsuku ezimbalwa ukuthi udokotela ahlaziye imiphumela yokuhlolwa futhi anikeze umbiko. Ngezinye izikhathi, uma imiphumela ingavamile, kungase kuxoxwe nabanye ochwepheshe.
Uma imiphumela yakho ibonisa ingozi yesifo senhliziyo, udokotela wakho uzokunikeza uhlelo lokwelapha ukuze anciphise leyo ngozi.
Umlayezo Wokuya Nawe Ekhaya
- I-Coronary Flow Reserve (CFR) iyisilinganiso 'samandla agciniwe' inhliziyo yakho enawo ukuze ikhulise ukugeleza kwegazi ngezikhathi zokucindezeleka.
- Lokhu kuhlolwa kunganikeza ulwazi olubalulekile mayelana nempilo yemithambo yegazi yenhliziyo. Kungasiza futhi ekuboneni izingozi zesifo senhliziyo esikhathini esizayo kusenesikhathi.
- Ngokuvamile, inani le-CFR elingaphezu kuka-2.0 liyisici esinempilo.
- Qiniseka ukuthi utshela udokotela wakho nganoma yimiphi imithi oyiphuzayo kanye nanoma yikuphi ukungezwani komzimba okungenzeka ukuthi unakho ngaphambi kokuhlolwa.
- Lolu vivinyo luphephile kakhulu. Uma unemibuzo mayelana nokuhlolwa, ungangabazi ukubuza udokotela wakho.
