Umhlobo wentliziyo yethu: Masifunde ngqo nge-Circumflex Artery!

Ngaba wakha wazibuza ukuba intliziyo yethu isebenza ngendlela emangalisayo kangakanani? Ngaphakathi kuloo ntliziyo incinci kukho inethiwekhi ebaluleke kakhulu yemithambo yegazi. Omnye wabahlobo abakhethekileyo kuloo nethiwekhi ubizwa ngokuba yi-'Circumflex Artery'. Ugqirha wakho usenokuyibiza ngokuba yi-'LCx' artery, okanye 'circum'. Ngoko ke, namhlanje, masithethe ngale 'Circumflex Artery' ngokweenkcukacha?

Yintoni i-'Circumflex Artery'? Masiyiqonde ngokulula!

Kulungile, cinga ngale ndlela. Kukho imithambo yegazi emibini ephambili ehambisa igazi entliziyweni yethu. Yimithambo yentliziyo ekhohlo neyasekunene. Umthambo wentliziyo oyintloko wasekhohlo (i-Left Main Coronary Artery) emva koko wahlulahlula ube ngamasebe amabini amancinci. Elinye lala masebe yi-circumflex artery esithetha ngayo. Elinye isebe yi-left anterior descending artery (LAD Artery). Oogqirha bakubiza oku ngokuthi yi-bifurcation yomthambo wegazi.

Ngoko ke, umsebenzi oyintloko wale `(Circumflex Artery)` kukuthwala igazi elicocekileyo nelinomoya-mpilo ngasemva nasemacaleni egumbi lokupompa kwicala lasekhohlo lentliziyo. Kufana nombhobho othwala amanzi ukuya kwimpompo yamanzi.

Kwenzeka ntoni kanye kanye ngale 'Circumflex Artery'?

Sinenkqubo ethwala igazi emzimbeni wethu wonke, esiyibiza ngokuba yiNkqubo yokujikeleza kwegazi. Le "Circumflex Artery" ngumthambo wegazi obalulekileyo oqhagamshelwe entliziyweni kuloo nkqubo.

Okwenzekayo apha kunokwahluka kancinci ngokuxhomekeke kwisakhiwo somzimba womntu ngamnye. Nangona kunjalo, kuye wonke umntu, la malungu alandelayo ecala lasekhohlo lentliziyo anikwa igazi elineoksijini eninzi yi-"Circumflex Artery":

• I-Atrium yasekhohlo – Eli ligumbi eliphezulu lasekhohlo lentliziyo.
• I-Left Ventricle – Eli ligumbi elikhulu kwicala lasekhohlo elisezantsi lentliziyo.
• Izihlunu ze-papillary ngaphakathi kwe-ventricle yasekhohlo.

Kwabanye abantu, kodwa kungengabo bonke, le `(Circumflex Artery)` inika igazi kwenye inxalenye ebalulekileyo yentliziyo. Leyo yi`Sinoatrial Node` (`SA Node`). Kwabaninzi abantu, lo msebenzi wenziwa yi-cardiovascular artery eyintloko echanekileyo. Le `(SA Node)` yinxalenye yenkqubo yombane yentliziyo elawula ukubetha kwentliziyo yethu. Oogqirha bakwayibiza ngokuba yi``pacemaker yendalo`` yentliziyo.

Ngoko ke iphi le `Circumflex Artery`?

Sele sitshilo ukuba umthambo wentliziyo oyintloko wasekhohlo wahlulwe ube ngamasebe amabini. Kulapho le `(Circumflex Artery)` iqala khona. Ikwindawo engaphandle yokukhusela yentliziyo ebizwa ngokuba yi`(Epicardium).` Ukuze kube yinyani, ihamba ngomjelo omncinci phakathi kwamagumbi amabini kwicala lasekhohlo lentliziyo.

Ingaba i-'Circumflex Artery' inamanye amasebe?

Ewe, le `(Circumflex Artery)` ikwakhupha amasebe amancinci. La abizwa ngokuba yi`Marginal Artery Branches`. Inani lala masebe alifani kuwo wonke umntu. Abanye abantu banokuba namasebe amathathu kuphela aya ecaleni elibizwa ngokuba yi`Obtuse Marginal Branches`. La masebe mancinci adla ngokuhamba ngaphandle kwe`Left Ventricle`, ukuya kwi`Apex` yayo.

Kwinani elincinci kakhulu labantu, le `(Circumflex Artery)` inelinye isebe elibizwa ngokuba yi`Left Posterior Ventricular – LPV Artery`. Nangona kunjalo, kubantu abaninzi, le `(LPV Artery)` (ekwabizwa ngokuba yi`Posterolateral Artery`) inelinye isebe elibizwa ngokuba yi`(Circumflex Artery)` elivela kumthambo omkhulu wentliziyo osekunene.

Yintoni iCoronary Arterial Dominance?

Le yingxaki enzulu kancinci, kodwa masizame ukuyiqonda ngokulula. Umthambo ophambili ohambisa igazi kumaleko ophakathi wemisipha (`Myocardium`) yentliziyo yethu yi`Posterior Descending Artery` (`PDA`). Ngoko ke, ukubaluleka komthambo wakho wentliziyo kugqitywa kukuba leliphi isebe lomthambo ophambili elihambisa igazi kule `(PDA)` esentliziyweni yakho.

Oku kunokwenzeka ngeendlela ezintathu eziphambili:

• Ukujikeleza kwegazi okuhamba ngokomthetho: Yile nto uninzi lwabantu (malunga nama-85 kwabali-100) abanayo. Apha, i-PDA ifumana igazi elivela kumthambo wentliziyo osekunene.
• Ukujikeleza kwegazi okuhamba ngasekhohlo: Oku kwenzeka kumntu omnye kwabalishumi. Apha, i-PDA inikwa igazi elivela kwi-Circumflex Artery okanye kwi-LAD Artery.
• Ukujikeleza kwegazi okuhamba ngegazi: Le meko yenzeka kubantu abamalunga naba-2 kwaba-10. I-PDA ifumana igazi elivela kwi-artery yentliziyo yasekunene nakwi-artery ye-circumflex yasekhohlo okanye kwi-artery ye-LAD.

Cinga ngayo njengombhobho wamanzi ophambili ophakela amanzi endlwini. Ezinye izindlu zifumana amanzi kuphela kumbhobho ongasekunene, ezinye ngasekhohlo, kwaye ezinye macala omabini.

Ngaba zikhona ezinye ii-arteries zohlobo lwe-'Circumflex' emzimbeni wethu?

Ewe, ukongeza kwi-"Circumflex Artery" entliziyweni, kukho nezinye iintlobo zemithambo-luvo emzimbeni wethu ezibizwa ngeli gama.

• Imithambo yeFemoral Circumflex: La ngamasebe amabini anzulu aphuma kumthambo wegazi oyintloko ethangeni lethu, iFemoral Artery. I-Femoral Artery ithwala igazi ukusuka esiswini ukuya emilenzeni. Ngamanye amaxesha, ngexesha lotyando lwe-coronary artery bypass, oogqirha bathatha iCircumflex Artery ethangeni baze bayisebenzise njenge-graft.
• Imithambo yeHumeral Circumflex:Ezi zahlulwe yi-`(Axillary Artery)` kwindawo yethu yekhwapha. Le `(Axillary Artery)` yiyo ethwala igazi ukusuka esifubeni ukuya emagxeni nasezingalweni. Ngokukodwa, ithambo lethu elingaphezulu lengalo (`Humerus`) linikwa igazi ikakhulu yi-`(Posterior Humeral Circumflex Artery)`.

Ziziphi izifo ezichaphazela i-'Circumflex Artery'?

Njengeminye imithambo yentliziyo, umthambo wentliziyo ojikelezayo unokuchaphazeleka sisifo esibizwa ngokuba sisifo semithambo yentliziyo (CAD). Oku kwenzeka xa i-fatty deposits (i-plaque) iqokelelana ngaphakathi komthambo, iwuvale. Kufana nokugqwala okuvalela umbhobho wamanzi.

Oku kwakheka kweplaque kunye nokuqina kweendonga zemithambo yegazi kubizwa ngokuba yi-atherosclerosis, oko kuthetha "ukuqina kwemithambo yegazi" okanye "ukuqina kwemithambo yegazi." Ukuba le meko ye-CAD ayinyangwa kakuhle, yandisa umngcipheko wokuba neemeko eziyingozi ezifana nokuhlaselwa yintliziyo, ukusilela kwentliziyo, kunye nestroke .

Zithini iimpawu zokuvaleka kwe-'Circumflex Artery'?

Xa ukuhamba kwegazi kuncipha ngenxa yokuncitshiswa kwemithambo yegazi, iintlungu zesifuba zinokubakho. Oku kubizwa ngokuba yi-"Angina". Le meko ye-"Angina" inokukhokelela ekuhlaselweni yintliziyo. Le yingxamiseko yezonyango, ngoko ke kufuneka utsalele umnxeba ku-911 ngoko nangoko.

Ekubeni ukuvaleka kwemithambo ye-circumflex kukwayinxalenye ye-CAD, iimpawu ziyafana. Usenokuhlangabezana nezinto ezifana nezi:

• (Angina) – Oku kuthetha intlungu yesifuba okanye ukuxinana.
• Ukubila okubandayo.
• Ukuba nesiyezi okanye ukuziva ukhathazekile.
• Ukudinwa kakhulu kunye nobuthathaka.
• Ukubetha kwentliziyo okukhawulezayo okanye okungahambelaniyo (I-Heart Palpitations).
• Isicaphucaphu .
• Ubunzima bokuphefumla .
• Intlungu egxalabeni okanye engalweni.
• Intlungu entanyeni okanye kumhlathi.

Oogqirha bayijonga njani impilo ye-'Circumflex Artery'?

Oogqirha basebenzisa uvavanyo oluhlukeneyo lokujonga imifanekiso ukujonga impilo yemithambo yakho yentliziyo, kuquka nemithambo ye-circumflex. Ezinye zazo ziquka:

• Ukucoca imithambo yegazi ngeCatheterization: Oku kujonga ukuba akukho zithintelo kwimithambo yegazi kunye nesifo semithambo yegazi yentliziyo.
• I-Coronary Computed Tomography Angiogram (CCTA): Oku kunokuvelisa imifanekiso ye-three-dimensional (3D) yokuhamba kwegazi entliziyweni.
• I-Intravascular Optical Coherence Tomography (IVOCT) okanye i-Intravascular Ultrasound (IVUS):Ezi ndlela zinokufumana imifanekiso ecacileyo yeplaque ngaphakathi kumthambo.
• I-Fractional Flow Reserve (FFR): Oku kulinganisa utshintsho kuxinzelelo lwegazi ngaphakathi kwemithambo yegazi kwaye kuqinisekisa ukuba ukuvaleka kukhulu ngokwaneleyo na ukuchaphazela ukusebenza kwentliziyo.

Zinyangwa njani iimeko ezichaphazela i-'Circumflex Artery'?

Ukuze uvule umthambo we-circumflex ovalekileyo, ugqirha wakho unokwenza i-catheterization yentliziyo aze enze iinkqubo zokungenelela ezifana ne-angioplasty kunye nokubekwa kwe-stent. I-Angioplasty yinkqubo esebenzisa isixhobo esifana nebhaluni ukwandisa umthambo ovalekileyo. I-stent yityhubhu encinci ye-wire mesh efakwa kumthambo ukuze incede ingaphinde inciphe.

Siyikhusela njani inkqubo yethu yemithambo yegazi, kuquka le `Circumflex Artery`?

Nazi ezinye izinto onokuzenza ukugcina imithambo yakho yegazi kunye nenkqubo yonke yokujikeleza kwegazi isempilweni:

• Yiba nomdla womzimba phantse yonke imihla yeveki kwaye ugcine ubunzima bakho busempilweni.
• Lawula indlela osela ngayo utywala. Fumana uncedo ukuba unengxaki yokusebenzisa utywala .
• Yitya ukutya okunempilo okunempilo yentliziyo . Oku kunokunceda ukunciphisa amanqanaba e-cholesterol .
• Qaphela iintlobo zamafutha owatyayo kwaye uzame ukunciphisa amafutha angondlekanga.
• Ukuba unesifo seswekile , silawule kakuhle.
• Thatha amanyathelo okulawula uxinzelelo lwegazi oluphezulu, kuquka ukunciphisa ubungakanani besodium (ityuwa) eyongezwa ekutyeni kwakho.
• Ukuba uyatshaya, cela uncedo lokuyeka .

Khumbula, njengesebe le-coronary artery yasekhohlo, i-`(Circumflex Artery)` yakho inokuba sengozini ye-`(Atherosclerosis)` kunye ne-`(Coronary Artery Disease)`. Ukuba i-`(Plaque)` iqokelelana kwi-`(Circumflex Artery)`, ukuhamba kwegazi entliziyweni kunokuphazamiseka. Oku kubizwa ngokuba yi-`(Bifurcation Blockage)`. Ukuba oku kuyenzeka, i-`(Angioplasty)` kunye ne-`(Stent)` zinokufuneka ukuvula i-artery kunye nokuphucula ukuhamba kwegazi.
