Ese twavuga ku 'Circumflex Artery', ifite akamaro kanini ku buzima bw'umutima?

Umutima ni nk'umuyoboro w'umubiri wacu. Rero, kugira ngo iyi moteri ikomeze gukora, ikenera amaraso ahoraho, ni ukuvuga ogisijeni n'intungamubiri. Kugira ngo umutima ushobore kohereza amaraso mu mubiri wose, hari uburyo butandukanye bw'imitsi mito itanga amaraso mu mutima. Iyi mitsi tuyita imitsi y'umutima. Kimwe mu bintu by'ingenzi muri iyo mitsi ni 'Circumflex Artery'. Uyu munsi, reka tuvuge ku muntu uwo ari we, icyo akora, n'uko bigenda iyo agize ikibazo.

Mu magambo make, Circumflex Artery ni iki?

Bitekerezeho muri ubu buryo. Dufite imitsi ibiri y’ingenzi y’umutima ijyana amaraso mu mutima wacu. Uw’iburyo n’uw’ibumoso. Uyu mutsi mukuru w’umutima w’ibumoso wigabanyamo andi mashami abiri y’ingenzi. Rimwe muri ayo mashami ni `Circumflex Artery` (irindi ryitwa `Left Anterior Descendeng (LAD) artery`). Hari igihe abaganga bayita `LCx artery` mu magambo ahinnye.

Akamaro k'ingenzi k'uyu mutsi ni ugutanga amaraso meza kandi afite ogisijeni mu byumba bitanga umwuka biri ibumoso bw'umutima wacu. Ni ukuvuga:

• Atrium y'ibumoso - Aho amaraso afite ogisijeni ava mu bihaha atangira guteranira.
• Inkondo y'ibumoso - Icyumba kinini kandi gikomeye cy'umutima gitanga amaraso ku mubiri wose.
• Imitsi yo mu nda iri mu gice cy'ibumoso cy'umutima.

Uyu mutsi uherereye he? Ese utera amashami?

Umutsi ugororotse uherereye mu gice cy'inyuma cy'umutima, ari na cyo gice cy'inyuma cy'umutima. Unyura mu gice gisa n'umuyoboro uri hagati y'ibyumba byo hejuru n'ibyo hasi (atrium na ventricle) ku ruhande rw'ibumoso rw'umutima.

Yego, kimwe n'amashami y'igiti, uyu mutsi nawo uvamo amashami mato. Umubare w'aya mashami uratandukanye. Ubusanzwe hari amashami agera kuri atatu, yitwa 'amashami marginal obtuse.' Aya mashami mato anyura inyuma y'umutima.

'Dominance' mu maraso ajyana umutima ni iki?

Ibi ni iby’ubuvuzi gato, ariko biroroshye kubyumva. Hari undi mutsi w’ingenzi witwa `umutsi umanuka inyuma (PDA)` utanga amaraso inyuma y’umutima wacu. Rero, `gutegeka imitsi y’umutima` kwawe bigenwa niba uyu mutsi w’umutima wa `PDA` uri mu mubiri wawe wakira amaraso avuye mu mutsi w’umutima w’iburyo cyangwa ishami riri ibumoso (ni ukuvuga `Circumflex` cyangwa `LAD`).

Iki ni ikintu gitandukanye bitewe n'umuntu ku wundi.

Ni izihe ndwara zigira ingaruka ku mutsi wa Circumflex Artery?

Kimwe n'indi mitsi ifata imitsi y'umutima, indwara nyamukuru kandi iteje akaga cyane yibasira `Circumflex Artery` ni indwara y'imitsi y'umutima (CAD) . Muri make, ni ukuziba kw'imitsi y'amaraso bitewe n'ibinure na cholesterol.

Nk’uko umwanda n’ingese byiyongera mu muyoboro w’amazi uko igihe kigenda gihita, ibintu nk’ibinure na cholesterol byiyongera muri iyo mitsi, bigakora urwego rwitwa `(plaque)`. Ibi tubyita `(atherosclerosis).` Uko uru rwego rw’`plaque`` rukura buhoro buhoro, ni ko amaraso yinjira mu mitsi agabanuka. Amaherezo, amaraso agenda ahagarara.

Wamenya ute ko umutsi ufunze? Ni ibihe bimenyetso?

Angina ibaho iyo umutsi ufunganye kandi umutima ntubone amaraso ahagije.Ushobora kugira ububabare mu gituza cyangwa gufungana, bizwi nka angina. Iki gishobora kuba ikimenyetso cy'indwara y'umutima, bityo rero ugomba kwitondera cyane ibi bimenyetso.

Niba ufite kimwe cyangwa byinshi muri ibi bikurikira, ni ikibazo cyihutirwa cy’ubuvuzi . Ugomba kujya ku bitaro byita ku barwayi barembye (ETU) byihutirwa.

Ni gute abaganga basuzuma imiterere y'imitsi?

Abaganga bakoresha ibizamini byinshi byihariye kugira ngo barebe ubuzima bw'imitsi yawe y'umutima, izwi kandi nka 'circumflex' arteries.

• Gupima umutima (Angiogram): Iki ni cyo kizamini cy'ingenzi cyane. Umuyoboro muto ushyirwa mu mitsi yo ku kuboko cyangwa ku kuguru, ugashyirwa mu mitsi y'umutima, ugaterwamo amazi yihariye, hanyuma hagafatwa X-ray kugira ngo harebwe niba hari ibiziba biri mu mitsi.
• Isuzuma rya "Coronary Computed Tomography Angiogram" (CCTA): Iyi ni isuzuma rya CT ridasanzwe rishobora kwerekana amashusho y’amaraso atembera mu mutima mu buryo bwa 3D.
• Ultrasound Intravascular (IVUS): Ibi bikubiyemo gushyira agakoresho gato ka ultrasound mu mitsi, bigatuma ingano n'imiterere y'urukuta rw'imitsi bigaragara neza.
• Isuzuma ry’umuvuduko w’amaraso (Fractional Flow Reserve - FFR): Ikizamini gipima umuvuduko w’amaraso mbere na nyuma yo kuziba mu mitsi kugira ngo hamenyekane neza uburyo kuziba kw’amaraso bigira ingaruka ku mikorere y’umutima.

Wavura ute umutsi ufunze?

Uburyo bw'ingenzi bwo kuvura bukoreshwa mu gufungura umutsi wa circumflex cyangwa indi mitsi ya coronary ni angioplasty na stent .

Muri ibi, umuyoboro muto ufite ipfundo ry’umupira unyura mu mitsi ukagera ahantu hafunze, nk'uko bipimwa angiogram. Hanyuma umuyoboro ushyirwamo umwuka kugira ngo usunike plaque ku rukuta rw'imitsi, bityo amaraso atembera neza. Hanyuma, umuyoboro muto witwa stent ushyirwa muri ako gace kugira ngo wirinde ko agace kafunganye kakongera kugabanuka. Ibi bifasha gukomeza gutembera neza kw'amaraso mu gihe kirekire.

Nakora iki kugira ngo umutima wanjye ukomeze kugira ubuzima bwiza?

Hari ibintu byinshi ushobora gukora kugira ngo umutima wawe wose n'imitsi yawe bikomeze kugira ubuzima bwiza, atari imitsi yawe ya circumflex gusa. Ikintu cyiza wakora ni ukubishyira mu mibereho yawe.

• Gira imyitozo ngororamubiri: Kora imyitozo ngororamubiri nibura iminota 30 hafi ya yose mu cyumweru. Kugenda n'amaguru, kwiruka, cyangwa koga ni amahitamo meza.
• Kurya indyo yuzuye umutima: Gabanya ibiryo birimo amavuta menshi, umunyu n'isukari. Shyiramo imbuto, imboga, ibinyamisogwe, amafi mato, n'ibinyampeke mu ndyo yawe.
• Gumana ibiro byiza: Kugumana ibiro bikwiranye n'uburebure bwawe ni ingenzi cyane.
• Irinde kunywa itabi burundu: Kunywa itabi ni umwe mu banzi bakomeye b'imitsi y'umutima.
• Kugenzura diyabete n'umuvuduko ukabije w'amaraso: Niba ufite izi ndwara, vugana na muganga wawe kugira ngo afate imiti yandikiwe kandi ayigenzure neza.
• Gabanya stress: Gerageza kuruhuka mu mutwe wawe ukoresheje ibintu nka yoga no gutekereza cyane.

Ukurikije ibi bintu, ushobora kubaho ubuzima burambye ufite umutima muzima. Niba ufite ikibazo icyo ari cyo cyose kijyanye n'ubuzima bwawe, saba inama kwa muganga w'umuryango wawe.
