Wakambozvibvunza here kuti chii chinoitika kumwoyo yedu patinorovedza muviri, kumhanya, kana kukwira masitepisi? Panguva iyoyo, mwoyo unoda okisijeni yakawanda kupfuura yawaiwanzoita. Kuti uwane okisijeni yakawanda, huwandu hweropa rinoyerera kuburikidza netsinga dzemwoyo dzinopa ropa kumoyo pacharo hunofanirawo kuwedzera. Saka, kugona kwemoyo wako kuwedzera kuyerera kweropa kana kudiwa kwacho kwawedzera kunongonzi Coronary Flow Reserve (CFR). Izvi zvakafanana ne'simba rekuchengetedza' remwoyo wako.
Chii chinonzi Coronary Flow Reserve (CFR)?
Zvichitaurwa zviri nyore, Coronary Flow Reserve (CFR) chiratidzo chekuti ropa rinoyerera zvakadii mutsinga dzemwoyo wako panguva yekurovedza muviri zvakanyanya. Izvi zvinogona kupa chiremba wako ruzivo rwakakosha nezvehutano hwemwoyo wako, kunyanya mamiriro etsinga dzinopa ropa kumoyo wako (coronary arteries).
Funga nezvazvo nenzira iyi. Paunenge wakagara pachigaro, mwoyo wako unoda ropa rakati. Asi paunongoerekana wamhanya uchitevera bhazi, basa remwoyo wako rinowedzera zvakanyanya. Mwoyo wako unoda oxygen yakapetwa katatu kusvika kana kana kupfuura yakajairwa. Mitsipa yeropa yemwoyo ine hutano inogona kubata kudiwa uku kwakawedzera, ichiwedzera kuyerera kweropa ipapo ipapo. Kuongororwa kweCFR kunoyera kugona kwemoyo wako kuita izvi.
Kuongororwa uku kunobatsira kuona nekukurumidza kana uine chirwere chemwoyo kana kuti uri panjodzi yekubatwa nechirwere chakadai sechirwere chemwoyo mune ramangwana.
Kukosha kweCFR kunoverengwa sei?
Maverengerwo anoitwa izvi ari nyore kwazvo. Chiremba wako anoyera kuyerera kweropa kuenda kumoyo wako nenzira mbiri.
1. Kuyerera kweropa panguva yekuzorora: Izvi zvinoyera huwandu hweropa rinoyerera richienda kumoyo paunenge wakazorora, pasina kushanda nesimba.
2. Kuyerera kweropa kwakanyanya: Mwoyo unomanikidzwa kupomba ropa nesimba guru (mushonga unopiwa weizvi), uye huwandu hweropa rinoyerera panguva iyoyo hunoyerwa.
Zvadaro, kuyerera kweropa uku kwakanyanya kunokamurwa neropa rakazorora.
CFR = (Kuyerera Kweropa Kwakanyanya) / (Kuyerera Kweropa Kunozorora)
Semuenzaniso, kana ropa rako rakawanda richiyerera katatu kupfuura iro raunozorora, CFR yako ichava 3.
Chii chinonzi avhareji yeCFR?
CFR yemunhu ane hutano inofanira kuva pakati pe2.0 ne2.5 . Izvi zvinoreva kuti moyo unofanirwa kukwanisa kupomba ropa rakawanda kaviri kupfuura zvaungagona kana wakazorora. Mumunhu ane hutano hwakanaka, chiyero ichi chinogona kuva 3, 4, kana kutopfuura.
- Kana kukosha kweCFR kuri pasi pe2.0:Izvi zvinoreva kuti panogona kunge paine dambudziko netsinga dzeropa dziri mumoyo. Pamwe tsinga dzeropa dzakatetepa (dzakavharika). Vanhu vakaita seizvi vari panjodzi huru yekubatwa nechirwere chemwoyo mune ramangwana.
- Kana CFR iri pamusoro pe2.0: Izvi zvinoratidza kuti mashandiro etsinga dzeropa mumoyo ari padanho rakanaka.
Asi chimwe chinhu chekurangarira ndechekuti huwandu hweCFR hunodzikira zvishoma nekukura. Nokudaro, huwandu hwakajairika hwemunhu wechidiki hunogona kusiyana nehuwandu hwakajairika hwemunhu mukuru. Chiremba wako chete ndiye anogona kududzira zvawakawana nemazvo.
Nzira yekuita sei bvunzo yeCFR?
Kune nzira mbiri huru dzekuita bvunzo iyi: imwe inzira yekupinda mumuviri, inosanganisira kuisa mudziyo mumuviri, uye imwe inzira yekunze, inosanganisira kuiita pasina kupinda mumuviri.
| Nzira yekuedza | Tsananguro iri nyore |
|---|---|
| Invasive - Cardiac Catheterization | Muizvi, chubhu yakatetepa (catheter) inopfuudzwa nepatsinga iri muruoko rwako, gumbo, kana mutsipa kuenda kutsinga dzemwoyo wako. Waya yakakosha inopfuudzwa kuti ione kumhanya kweropa. Izvi zvinogona kuitwa panguva imwe chete neangiogram. |
| Nzira isingakuvadzi - PET Scan | Iyi i scan yakakosha. Mubvunzo uyu, unopihwa huwandu hushoma hwechinhu chine radioactive (radiotracer) kuburikidza neIV. Zvadaro, PET scanner inoyera kufamba kweropa nekuona kuti chinhu chacho chinofamba sei mumoyo. |
| Dzimwe nzira - Cardiac MRI | Ukuwo kuskena kwekunze, asi nzira iyi haiwanzo shandiswa kuyera CFR. |
Unofanira kugadzirira sei bvunzo isati yaitwa?
Chiremba wako achakutsanangurira izvi. Kazhinji, unofanira kungwarira nezvezvinhu izvi.
- Ruzivo rweMishonga: Udza chiremba wako nezvemishonga yese yauri kutora (yakanyorwa nachiremba uye yaunotenga kunze kwemushonga unonyorerwa chiremba). Mimwe mishonga inogona kukanganisa kuumbwa kweropa uye unogona kukumbirwa kuti urege kuitora zuva risati rasvika bvunzo.
- Kurwara: Iva nechokwadi chekutiudza kana uine allergies kune chero mishonga kana contrast dye.
- Kutsanya: Kana uri kubatwa catheterization yemwoyo kana PET scan, unorayirwa kuti usadye kana kunwa kwemaawa matanhatu kusvika masere bvunzo isati yaitwa.
- Pakuongororwa kweMRI: Haufanirwe kupfeka zvinhu zvesimbi (zvishongo, mawachi) pamuviri wako. Kana uine mudziyo wakaita sepacemaker mumuviri wako, bvunza chiremba wako pachine nguva kana zvakachengeteka paMRI.
Chii chekutarisira panguva yebvunzo?
Pasinei nenzira yekuyedza yaunayo, chubhu yeIV (cannula) ichaiswa muruoko rwako. Matanho ekuyedza achataridzika seizvi.
1. Kuyerwa kwemamiriro ekuzorora: Kutanga, kuyerera kweropa mumoyo mako kunoyerwa paunenge wakadzikama uye wakazorora.
2. Kupa mushonga: Tevere, mushonga (vasodilator) unotambanudza tsinga dzeropa mumoyo mako uye unowedzera kuyerera kweropa unopihwa kuburikidza neIV. Mushonga unonyanya kushandiswa iAdenosine . Kana wapihwa, kuyerera kweropa kuenda kumoyo kunowedzera ka4-5 mukati memaminitsi maviri-matatu.
3. Kuyera ropa zvakanyanya: Kana ropa rasvika padanho rayo guru mushure mekunge mushonga wapihwa, ropa rinoyerwa zvakare.
4. Kuenzanisa: Chekupedzisira, zviyero zviviri izvi zvinoenzaniswa kuti zviverengere kukosha kweCFR yako.
Kana uri kubatwa nechirwere chemwoyo chinonzi cardiac catheterization, unogona kupiwa mushonga wekunyaradza kuti ukwanise kurara zvishoma. Izvi zvichakubatsira kuti usanyanya kugadzikana. Paunenge uchiongororwa, zvakakosha kuti urambe wakamira kuti uwane mifananidzo yakajeka.
Chii chinoitika mushure mekuyedzwa?
Mushure mekuongororwa, unogona kurarama zvakanaka, asi unofanira kungwarira pane zvimwe zvinhu.
- Kana wakambobatwa necardiac catheterization, unofanira kuchengeta ruoko kana gumbo panzvimbo pakaiswa catheter rakamira kweinenge awa imwe chete kudzivirira kubuda ropa.
- Chiremba achakukurudzira kuti unwe mvura yakawanda kuti dhayi yemhando ye contrast ibude mumuviri wako nekukurumidza.
- Kana wakapihwa mushonga wekunyaradza, haugone kutyaira motokari zuva iroro. Zvakakosha kuti mumwe munhu akuperekedze kumba.
Pane njodzi here kana kuti migumisiro yakaipa pabvunzo iyi?
Kuongororwa kweCFR kunowanzo kuve kwakachengeteka, asi sezvinoitwa chero bvunzo dzekurapa, kune dzimwe njodzi diki.
- Njodzi dzine chekuita necatheter:Panguva yekuisa catheter mumoyo, ropa rinogwamba, kukuvara kwetsinga dzeropa, kana kubuda ropa hazviwanzoitiki.
- Migumisiro ye adenosine: Vamwe vanhu vanogona kusangana nezvinotevera kwemasekondi mashoma mushure mekupihwa mushonga uyu:
- Kurira kwemoyo kusina kujairika
- Kuderera kweropa mumuviri
- Kuoma kufema
- Kusagadzikana pachipfuva
Zviratidzo izvi zvinopera zvachose kana mushonga wapera (mukati meminiti imwe chete) . Hapana chekunetseka nazvo.
Zvakakosha: Adenosine haina kukodzera vanhu vane asthma nekuti inogona kukonzera bronchospasm . Kana uine asthma, chiremba wako achashandisa mumwe mushonga panzvimbo pezvo.
Zvinorevei mhedzisiro yacho uye tichazviziva riini?
CFR yako inhamba inokuudza kuti mwoyo wako unogona kupomba ropa rakadii kana uine stress.
Zvinogona kutora mazuva mashoma kuti chiremba aongorore zvabuda muongororo uye ape mushumo. Dzimwe nguva, kana zvabuda zvisina kunaka, dzimwe nyanzvi dzinogona kubvunzwa.
Kana zvawanikwa zvichiratidza kuti une njodzi yechirwere chemwoyo, chiremba wako achakupa hurongwa hwekurapa kuti aderedze njodzi iyoyo.
Mharidzo Yekuenda Nayo Kumba
- Kuyerera kweropa mumoyo (Coronary Flow Reserve - CFR) inzira yekuyera simba remwoyo wako rekuwedzera kuyerera kweropa panguva yekushushikana.
- Kuongororwa uku kunogona kupa ruzivo rwakakosha nezvehutano hwetsinga dzemwoyo. Kunogonawo kubatsira kuona njodzi dzezvirwere zvemwoyo munguva pfupi iri kutevera.
- Kazhinji, kukosha kweCFR kupfuura 2.0 chiratidzo chine hutano.
- Iva nechokwadi chekuudza chiremba wako nezvemishonga yauri kutora uye chero allergies yaungave nayo usati waongororwa.
- Iyi bvunzo yakachengeteka zvikuru. Kana muine mibvunzo nezvebvunzo iyi, musazeza kubvunza chiremba wenyu.
