Mwoyo wakafanana neinjini yemuviri wedu. Saka, kuti injini iyi irambe ichishanda, inoda ropa rinogara richiwanikwa, kureva okisijeni nezvinovaka muviri. Kuti mwoyo upombe ropa mumuviri wese, pane imwe nzira yakasiyana yetsinga diki dzinopa ropa kumoyo. Tinodzidaidza kuti idzi tsinga dzemwoyo. Imwe nhengo inokosha kwazvo yehurongwa i'Circumflex Artery'. Nhasi, ngatitaurei nezvekuti uyu ndiani, chii chaanoita, uye chii chinoitika kana aine dambudziko.
Zvichitaurwa zviri nyore, chii chinonzi Circumflex Artery?
Zvakanaka, funga nezvazvo nenzira iyi. Tine tsinga mbiri huru dzemoyo dzinotakura ropa kuenda kumoyo wedu. Yerudyi neYeruboshwe. Iyi tsinga huru yemoyo yekuruboshwe inopatsanurana kuita mamwe matavi maviri makuru. Rimwe rematavi iwayo i'Circumflex Artery' (rimwe rinonzi 'Left Anterior Descending (LAD) artery'). Vanachiremba dzimwe nguva vanodana iyi kuti 'LCx artery' muchidimbu.
Basa guru retsinga iyi nderekupa ropa rakachena, rine oxygen kumakamuri ekupomba ari kuruboshwe rwemoyo wedu. Ndizvo:
- Atrium yekuruboshwe - Panotanga kuungana ropa rine oxygen kubva mumapapu.
- Ventricle yekuruboshwe - Kamuri guru uye rakasimba kwazvo remwoyo rinopomba ropa kumuviri wese.
- Tsandanyama dzepapillary dziri mukati me ventricle yekuruboshwe.
Mune vamwe vanhu, iyi tsinga yeropa inonzi 'circumflex' ine rimwe basa rakakosha. Iri nderekupa ropa ku 'sinoatrial (SA) node', iyo inodzora kurova kwemoyo, ichiita se 'natural pacemaker' yemoyo. Asi muvanhu vazhinji, basa iri rinoitwa netsinga yeropa yemoyo yakarurama.
Mutsinga uyu uri kupi? Unoburitsa matavi here?
Tsinga yetsinga yecircumflex iri mukati me epicardium, chikamu chekunze chekudzivirira chemwoyo. Inofamba nechikamu chakaita segomba pakati pemakamuri epamusoro neapasi (atrium neventricle) kuruboshwe rwemoyo.
Ehe, kungofanana nemapazi emuti, tsinga iyi inobudawo ichiita matavi madiki. Huwandu hwematavi aya hunogona kusiyana. Kazhinji kune matavi angangoita matatu, anonzi 'obtuse marginal branches.' Matavi madiki aya anofamba achidzika nekunze kwe ventricle yekuruboshwe yemoyo.
Chii chinonzi 'Dominance' muropa rinoenda kumwoyo?
Izvi zvine chekuita nekurapa, asi zviri nyore kunzwisisa. Kune imwe tsinga inokosha inonzi `posterior descending artery (PDA)` inoendesa ropa kumashure kwemoyo wedu. Saka, `coronary arterial dominance` yako inoonekwa kana iyi `PDA` artery iri mumuviri wako inogamuchira ropa kubva ku right coronary artery kana bazi riri kuruboshwe (kureva `Circumflex` kana `LAD`).
Ichi chinhu chinosiyana kubva pamunhu kusvika pamunhu.
| Rudzi rwekutonga | Tsananguro iri nyore |
|---|---|
| Kutonga kurudyi | Vanhu vazhinji (vanenge 85%) vane izvi. Pano, tsinga yePDA inogamuchira ropa kubva mutsinga yemwoyo yekurudyi. |
| Kudzora kuruboshwe | Izvi zvinoitika kune munhu mumwe chete pavanhu gumi. Pano, tsinga yePDA inogamuchira ropa kubva mutsinga yeCircumflex (kana kuti LAD artery). |
| Chinoumba huwandu hwezvinhu | Vanhu vaviri pavanhu gumi vanogona kuva nepfungwa iyi. Pano, PDA inowana ropa kubva mutsinga dzerudyi nedzeruboshwe (Circumflex kana LAD). |
Ndezvipi zvirwere zvinokanganisa Circumflex Artery?
Kufanana nedzimwe tsinga dzemwoyo, chirwere chikuru uye chine njodzi zvikuru chinokanganisa `Circumflex Artery` chirwere chemwoyo (CAD) . Zvichitaurwa zviri nyore, kuvharika kwetsinga dzemwoyo nemafuta nemafuta echolesterol.
Kungofanana nevhu nengura zvinoungana mupombi yemvura nekufamba kwenguva, zvinhu zvakaita semafuta necholesterol zvinoungana mutsinga idzi, zvichiumba jira rinonzi `(plaque)`. Tinozvidaidza kuti `(atherosclerosis).` Sezvo jira iri re `plaque`` richikura zvishoma nezvishoma, kuyerera kweropa mukati metsinga kunopera. Pakupedzisira, kuyerera kweropa kunovharika.
Kana chirwere ichi chikasarapwa zvakanaka, chinogona kukonzera zvirwere zvakakomba zvakaita sekurwadziwa kwemoyo, kutadza kushanda zvakanaka kwemoyo, kana sitiroko .
Unoziva sei kana tsinga yakavharwa? Ndezvipi zviratidzo?
Angina inoitika kana tsinga yeropa ikava diki uye moyo usingawani ropa rakakwana.Unogona kunzwa kurwadziwa muchipfuva kana kuomarara, kunozivikanwa se angina. Izvi zvinogona kuva chiratidzo chekurwara nemoyo, saka unofanira kungwarira zvikuru nezvezviratidzo izvi.
Kana uine chimwe chezviratidzo zvinotevera kana kupfuura, idambudziko rehutano . Unofanira kuenda kuchipatara cheEmergency Department (ETU) nekukasika.
| Chiratidzo | Tsananguro |
|---|---|
| Kurwadziwa/kusimba kwechipfuva `(Angina)` | Kunzwa kubatwa, kudzvanywa, uye kurema pakati pechipfuva. |
| Marwadzo anopenya kuruoko rweruboshwe, pafudzi, pamutsipa, pashaya | Marwadzo anotangira muchipfuva opararira kunzvimbo idzi. |
| Kuoma kufema | Kushaya mweya, kufema zvakaoma kunyangwe pasina kushanda nesimba. |
| Kunzwa kutonhora uye kudikitira | Kunzwa kutonhora uye kudikitira zvakanyanya pasina chikonzero. |
| Dzungu, kunzwa sekunge uri kutenderera. | Kunzwa dzungu zvekuti haugone kumira. |
| Kuneta, kushaya simba | Kuneta kwakanyanya uye kushaya simba kwemuviri kamwe kamwe. |
Vanachiremba vanoongorora sei mamiriro etsinga?
Vanachiremba vanoshandisa bvunzo dzakasiyana-siyana kuti vaone hutano hwetsinga dzemwoyo, dzinozivikanwawo setsinga dze'circumflex'.
- Kuongororwa kweCatheterization yeMwoyo (Angiogram): Iyi ndiyo bvunzo inonyanya kukosha. Chubhu diki inopinzwa nepatsinga iri muruoko kana gumbo, yoiswa mutsinga dzemwoyo, yobayiwa mvura yakakosha, uye X-ray inotorwa kuti ione kana paine kuvharika kwetsinga.
- Coronary Computed Tomography Angiogram (CCTA): Iyi iCT scan yakakosha inogona kuburitsa mifananidzo ye3D yekufamba kweropa mumoyo.
- Intravascular Ultrasound (IVUS): Izvi zvinosanganisira kupinza mudziyo mudiki weultrasound mukati metsinga, zvichiita kuti saizi uye hunhu hweplaque layer yakabatana nemadziro etsinga zvionekwe zvakajeka.
- Kuongororwa kweFractional Flow Reserve (FFR): Kuongororwa kunoyera BP isati yavharika mutsinga uye mushure mekuvharika kwayo kuti zvionekwe kuti kuvharika kwayo kunokanganisa sei mashandiro emoyo.
Unorapa sei tsinga yakavharika?
Kurapa kukuru kunoshandiswa kuvhurazve tsinga yeropa yakavharika kana imwe tsinga yeropa ndeye angioplasty uye stent .
Muizvi, chubhu diki ine muromo webharumu inopfuudzwa nemutsinga kuenda kunzvimbo yakavharika, sezvinoitwa angiogram. Bharumu rinozofefeterwa kuti risundire plaque pamadziro etsinga, zvichiita kuti ropa riwedzere kuyerera. Zvadaro, chubhu diki inonzi stent inoiswa munzvimbo iyi kudzivirira nzvimbo yakamanikana kuti isarambe ichiderera zvakare. Izvi zvinobatsira kuchengetedza kufamba kweropa kwakanaka kwenguva refu.
Ndingaitei kuti mwoyo wangu ugare wakasimba?
Pane zvinhu zvakawanda zvaunogona kuita kuti mwoyo wako wese uye hurongwa hwetsinga dzeropa zvirambe zvakanaka, kwete chete tsinga yako yeropa inotenderera. Chinhu chakanakisa chekuita ndechekuisa izvi mumararamiro ako.
- Iva nemuviri unoshanda: Rovedza muviri kwemaminitsi makumi matatu mazuva mazhinji evhiki. Kufamba, kumhanya, kana kushambira isarudzo dzakanaka.
- Idya chikafu chine hutano pamoyo: Deredza chikafu chine mafuta akawanda, munyu, uye shuga. Isa michero, miriwo, nyemba, hove diki, uye zviyo zvakakwana mukudya kwako.
- Ramba uine huremu hwakanaka: Kuchengeta huremu hwakakodzera kureba kwako kwakakosha zvikuru.
- Dzivisa kusvuta zvachose: Kusvuta ndeimwe yevavengi vakuru vetsinga dzemwoyo.
- Dzora chirwere cheshuga neBP: Kana uine zvirwere izvi, taura nachiremba wako kuti anwe mishonga yawakanyorerwa uye kuti irambe ichidzorwa zvakanaka.
- Deredza kushushikana: Edza kuzorodza pfungwa dzako kuburikidza nezvinhu zvakaita seyoga nekufungisisa.
Nekutevera zvinhu izvi, unogona kurarama hupenyu hurefu nemoyo une hutano. Kana uine mibvunzo nezveutano hwako, bvunza chiremba wemhuri yako kuti akupe mazano.
Mharidzo Yekuenda Nayo Kumba
- `Circumflex Artery` itsinga yemwoyo inokosha zvikuru inopa ropa kuruboshwe rwemoyo wako.
- Mafuta ari mutsinga iyi anogona kukonzera kuti ivharike (CAD), izvo zvinogona kukonzera zvirwere zvakakomba zvakaita sekurwadziwa kwemoyo.
- Usambofa wakafuratira zviratidzo zvakaita sekurwadziwa muchipfuva, kunetseka kufema, kutonhora, uye kudikitira. Idambudziko rekukurumidza. Enda kuchipatara kuEmergency Department (ETU) nekukasika.
- Mararamiro ane hutano (kudya zvakanaka, kurovedza muviri, uye kusaputa fodya) zvinogona kudzivirira tsinga dzako dzeropa.
- Kana uine zvinokunetsa nezveutano hwemwoyo wako, taura nachiremba wako nekukurumidza.
