Kodi tikambirane za 'Circumflex Artery', yomwe ndi yofunika kwambiri pa thanzi la mtima?

Mtima uli ngati injini ya thupi lathu. Choncho, kuti injini iyi igwire ntchito, imafunika magazi nthawi zonse, kutanthauza mpweya ndi zakudya. Kuti mtima uzitha kupopera magazi kupita ku thupi lonse, pali njira yosiyana ya mitsempha yaying'ono yomwe imapereka magazi kupita ku mtima. Timaitcha mitsempha ya mtima. Chiwalo chimodzi chofunikira kwambiri cha dongosololi ndi `Circumflex Artery`. Lero, tiyeni tikambirane za ameneyu, zomwe amachita, ndi zomwe zimachitika ngati ali ndi vuto.

Mwachidule, kodi Circumflex Artery ndi chiyani?

Chabwino, taganizirani motere. Tili ndi mitsempha iwiri ikuluikulu ya mtima yomwe imanyamula magazi kupita kumtima mwathu. Wamanja ndi wamanzere. Mitsempha yayikulu ya mtima iyi imagawika m'nthambi ziwiri zazikulu. Imodzi mwa nthambi zimenezo ndi `Circumflex Artery` (inayo imatchedwa `Left Anterior Descending (LAD) artery`). Madokotala nthawi zina amatcha iyi `LCx artery` mwachidule.

Ntchito yaikulu ya mtsempha uwu ndikupereka magazi oyera, okhala ndi mpweya ku zipinda zopopera kumanzere kwa mtima wathu. Izi ndi izi:

• Atrium yakumanzere - Kumene magazi opangidwa ndi mpweya wochokera m'mapapo amayamba kusonkhana.
• Chipinda cha kumanzere - Chipinda chachikulu komanso champhamvu kwambiri cha mtima chomwe chimapopera magazi kupita ku thupi lonse.
• Minofu ya papillary mkati mwa ventricle yakumanzere.

Kodi mtsempha uwu uli kuti? Kodi umafalikira?

Mtsempha wa circumflex uli mkati mwa epicardium, gawo lakunja loteteza mtima. Umayenda m'mbali ngati mpata pakati pa zipinda zapamwamba ndi zapansi (atrium ndi ventricle) kumanzere kwa mtima.

Inde, monga nthambi za mtengo, mtsempha uwu umafalikiranso m'nthambi zazing'ono. Chiwerengero cha nthambi izi chimasiyana. Nthawi zambiri pamakhala nthambi zitatu, zotchedwa 'nthambi za obtuse marginal.' Nthambi zazing'onozi zimayenda pansi kunja kwa ventricle yakumanzere ya mtima.

Kodi 'Dominance' m'magazi opita kumtima ndi chiyani?

Izi ndi zachipatala pang'ono, koma n'zosavuta kuzimvetsa. Pali mtsempha wina wofunikira wotchedwa `posterior descending artery (PDA)` womwe umapereka magazi kumbuyo kwa mtima wathu. Chifukwa chake, `coronary arterial dominance` yanu imatsimikiziridwa ngati mtsempha uwu wa `PDA` m'thupi lanu umalandira magazi kuchokera ku mtsempha wakumanja wa mtima kapena nthambi kumanzere (monga `Circumflex` kapena `LAD`).

Ichi ndi chinthu chomwe chimasiyana malinga ndi munthu.

Ndi matenda ati omwe amakhudza Circumflex Artery?

Monga mitsempha ina ya mtima, vuto lalikulu komanso loopsa kwambiri lomwe limakhudza `Circumflex Artery` ndi matenda a mitsempha ya mtima (CAD) . Mwachidule, ndi kutsekeka kwa mitsempha ya mtima ndi mafuta ndi cholesterol.

Monga momwe dothi ndi dzimbiri zimakhalira mu chitoliro cha madzi pakapita nthawi, zinthu monga mafuta ndi cholesterol zimakulirakulira m'mitsempha iyi, ndikupanga wosanjikiza wotchedwa `(plaque)`. Timatcha izi `(atherosclerosis).` Pamene wosanjikiza uwu wa `plaque`` ukukula pang'onopang'ono, kuyenda kwa magazi mkati mwa mtsempha kumachepa. Pamapeto pake, kuyenda kwa magazi kumatsekedwa.

Kodi mumadziwa bwanji ngati mtsempha watsekeka? Kodi zizindikiro zake ndi ziti?

Angina imachitika pamene mtsempha wamagazi wachepa ndipo mtima sulandira magazi okwanira.Mungakhale ndi kupweteka pachifuwa kapena kufinya, komwe kumatchedwa angina. Ichi chingakhale chizindikiro cha matenda a mtima, choncho muyenera kusamala kwambiri ndi zizindikiro izi.

Ngati muli ndi chimodzi kapena zingapo mwa zizindikiro zotsatirazi, ndi vuto lachipatala . Muyenera kupita ku Dipatimenti Yoona za Zadzidzidzi (ETU) ya chipatala nthawi yomweyo.

Kodi madokotala amayesa bwanji momwe mitsempha ilili?

Madokotala amagwiritsa ntchito mayeso apadera angapo kuti aone momwe mitsempha yanu ya mtima ilili, yomwe imadziwikanso kuti mitsempha ya 'circumflex'.

• Kuyeza kwa Mtima (Angiogram): Iyi ndi njira yofunika kwambiri yoyezera. Kachubu kakang'ono kamalowetsedwa kudzera m'mitsempha ya m'dzanja kapena mwendo, kenako kamalumikizidwa ku mitsempha ya mtima, kenako kamabayidwa ndi madzi apadera, ndipo X-ray imatengedwa kuti ione ngati pali zotsekeka zilizonse m'mitsempha.
• Coronary Computed Tomography Angiogram (CCTA): Iyi ndi njira yapadera yojambulira ya CT yomwe ingathe kupanga zithunzi za magawo atatu (3D) za kayendedwe ka magazi mumtima.
• Ultrasound ya m'mitsempha (IVUS): Izi zimaphatikizapo kulowetsa chipangizo chaching'ono cha ultrasound mkati mwa mtsempha, zomwe zimathandiza kuti kukula ndi mtundu wa plaque yomwe ili pakhoma la mtsempha ziwonekere bwino kwambiri.
• Kusunga Mayendedwe a Magazi (FFR): Kuyesa komwe kumayesa kuthamanga kwa magazi mumtsempha musanatsekeke komanso mutatha kutsekeka kuti mudziwe momwe kutsekekako kumakhudzira ntchito ya mtima.

Kodi mumachiritsa bwanji mtsempha wotsekeka?

Chithandizo chachikulu chomwe chimagwiritsidwa ntchito potsegulanso mtsempha wotsekeka wa circumflex kapena mtsempha wina wa mtima ndi angioplasty ndi stent .

Mu izi, chubu chaching'ono chokhala ndi nsonga ya baluni chimadutsa mumtsempha kupita kumalo otsekeka, monga momwe zimakhalira ndi angiogram. Kenako baluniyo imadzazidwa kuti ikankhire plaque kukhoma la mtsempha, ndikukulitsa kuyenda kwa magazi. Kenako, chubu chaching'ono chotchedwa stent chimayikidwa m'derali kuti chiteteze malo otsekeka kuti asatsekenso. Izi zimathandiza kuti magazi aziyenda bwino kwa nthawi yayitali.

Kodi ndingatani kuti mtima wanga ukhale wathanzi?

Pali zinthu zambiri zomwe mungachite kuti mtima wanu wonse ndi mitsempha yamagazi ikhale yathanzi, osati mitsempha yanu yokha ya circumflex. Chinthu chabwino kwambiri choti muchite ndikuphatikiza izi mu moyo wanu.

• Khalani ndi masewera olimbitsa thupi: Chitani masewera olimbitsa thupi kwa mphindi zosachepera 30 masiku ambiri a sabata. Kuyenda, kuthamanga, kapena kusambira ndi njira zabwino.
• Idyani zakudya zopatsa thanzi pamtima: Chepetsani zakudya zokhala ndi mafuta ambiri, mchere, ndi shuga. Phatikizani zipatso, ndiwo zamasamba, nyemba, nsomba zazing'ono, ndi tirigu wonse muzakudya zanu.
• Khalani ndi kulemera koyenera: Kusunga kulemera koyenera kutalika kwanu n'kofunika kwambiri.
• Pewani kusuta fodya konse: Kusuta fodya ndi mdani wamkulu wa mitsempha ya mtima.
• Lamulirani matenda a shuga ndi kuthamanga kwa magazi: Ngati muli ndi matenda awa, lankhulani ndi dokotala wanu kuti amwe mankhwala omwe mwapatsidwa ndikuwayang'anira bwino.
• Chepetsani kupsinjika maganizo: Yesetsani kupumula maganizo anu pogwiritsa ntchito zinthu monga yoga ndi kusinkhasinkha.

Mukatsatira zinthu izi, mutha kukhala ndi moyo wautali ndi mtima wathanzi. Ngati muli ndi mafunso okhudza thanzi lanu, funsani dokotala wa banja lanu kuti akupatseni malangizo.
