Ese hari ikibazo kiri mu mitsi yawe y'amaraso? Reka twige ku bijyanye n'imikorere mibi y'imyakura.

Ese wigeze utekereza ku kamaro k'imitsi y'amaraso mu mibiri yacu? Ni nk'imihanda mito itwara ubutumwa n'intungamubiri mu mibiri yacu yose. None se bigenda bite iyo hari intege nke mu gice cyoroshye kiri muri iyi mihanda, cyitwa endothelium? Ni cyo twita "Endothelial Dysfunction". Reka tuvuge kuri ibi gato, sibyo?

Ikibazo cyo kudakora neza kw'imyanya y'imbere ni iki?

Mu magambo make, kudakora neza kw'ingirabuzimafatizo z'amaraso ni igihe urwego ruto rw'uturemangingo turi mu miyoboro y'amaraso yawe rwitwa endothelium rudakora neza. Utu turemangingo tw'ingirabuzimafatizo z'amaraso ubusanzwe dufasha imiyoboro y'amaraso kugumisha ifunguye (yagutse) iyo bikenewe. Ariko iyo habayeho kudakora neza, ibinyuranye n'ibyo bibaho. Ni ukuvuga ko imiyoboro y'amaraso itangira gufunga no kugabanuka.

Tekereza nk'umuyoboro w'amazi. Niba igice cy'imbere kidakora neza, bizagorana ko amazi anyuramo, sibyo? Uko ni ko bimeze. Impamvu nyamukuru y'iyi ndwara ni indwara yitwa "Vasospasm" ifitanye isano n'imitsi y'umutima. Muri ibi, nubwo nta kintu na kimwe kiba cyazibye mu mitsi y'umutima, imitsi irafungana. Nanone, "Endothelial Dysfunction" yongera ibyago byo kurwara "Atherosclerosis", ari byo bitera ibinure ku nkuta z'imitsi no kugabanya imitsi.

None se uru ruhare rw'iyi endothelium ni uruhe?

Buri mutsi w'amaraso mu mubiri wacu (ni ukuvuga imitsi, imitsi, imitsi yo mu bwonko) ushyizwe imbere mu gice kimwe cy'uturemangingo twitwa uturemangingo tw'amaraso. Wari uzi ko iyi endothelium ari imwe mu ngingo nini mu mubiri wacu!

Uturemangingo tw’amaraso dusohora ibintu bitandukanye. Ibi bintu bigenzura uburyo imitsi ifunguka n’ifungwa (ibi byitwa "Vascular Tone". Iyi "Vascular Tone" ni yo igena umuvuduko w’amaraso yacu, n’uburyo umutima urushaho gukomera mu gupompa amaraso.

Si ibyo gusa, ahubwo endothelium yawe ubwayo ikora izindi nshingano nyinshi z'ingenzi:

• Igenzura amazi n'ibinyabutabire mu maraso yawe.
• Bifasha kubumba amaraso iyo bikenewe.
• Birinda uburozi kwinjira mu turemangingo.
• Igenzura ububyimbirwe mu ngingo.

Tekereza gato ukuntu uru rugingo ruto rw'uturemangingo rukora akazi kangana iki mu mubiri wacu!

Ni mu rugero rungana iki iyi ndwara yitwa imikorere mibi ya endothelium?

Inzobere mu by'ubuvuzi zimaze igihe kinini zitekereza ko endothelium ari uruzitiro ruri mu mitsi y'amaraso. Ariko nyuma byaje kugaragara ko iyi nayo ari ingingo y'ingenzi. Ni bwo iyi ndwara yitwa "Endothelial Dysfunction" ishobora gufatwa nk'indwara itandukanye.

Ibi byavumbuwe mu mpera za 1990, bivuze ko iyo ndwara itamenyekanye igihe kirekire. Bityo rero abahanga ntibashobora kuvuga neza uburyo yakwirakwiriye mu bantu.

Kuki habaho iyi mikorere mibi y'inyuma y'umuyoboro w'amaraso?

Impamvu nyamukuru y’iki kibazo ni uko nta gaze ihagije yitwa Nitric Oxide (NO) iba mu nkuta z’imitsi yawe y’amaraso. Igitangaje ni uko iyi nitric oxide ikorwa na endothelium yawe ubwayo! Iyi nitric oxide ni ``(Vasodilator)``, bivuze ko ifungura imitsi y’amaraso kandi igatuma amaraso atembera neza.

None se, bigenda bite iyo urugero rwa nitrike oxide rugabanutse?

• Imitsi y'amaraso irafungana: Ibi bishobora gutera umuvuduko ukabije w'amaraso.
• Kubyimba biba mu nkuta z'imitsi: Ibi bishobora gutera indwara ya atherosclerosis, cyangwa gukomera kw'imitsi.
• Umusaruro w'udupira tw'amaraso uriyongera: Ibi bishobora gutera kubyimba kw'amaraso.
• Inkuta z'imitsi y'amaraso ziba zifite imyenge: Ibi bituma ingirabuzimafatizo zigira lipoproteins mbi n'ubundi burozi.

Ni ibihe bimenyetso by'imikorere mibi y'imyanya y'imbere (Endothelial)?

Ikimenyetso cy'ingenzi cy'indwara y'imitsi ijyana amaraso mu mutima (imikorere mibi y'amaraso mu nda) ni angina , ari byo kubabara mu gituza. Ubu bubabare mu gituza buterwa n'uko imitsi yawe iba ifunze igihe igomba gufungura. Ubu bubabare mu gituza bukunze kwiyongera cyane mu gihe cy'imyitozo ngororamubiri.

Hari abantu bashobora kugira ububabare bw'agatuza budashira (`Angina`) nubwo ntacyo bakora. Ibi bishobora kuba ikimenyetso cy'indwara y'umutima. Ibi nibibaho, ibimenyetso birimo ububabare bw'agatuza budashira, umunaniro ukabije, no kubura umwuka. Iki ni ikibazo cyihutirwa cya muganga gisaba kuvurwa vuba.

Ni nde uri mu kaga gakomeye kuri ibi? (Ibintu bishobora gutera ibyago)

Hari ibintu bimwe na bimwe bishobora kongera ibyago byo kurwara indwara yo mu nda. Ufite ibyago byinshi niba ufite ibi bikurikira:

• Diyabete (`Diabete Mellitus`)
• Umuvuduko ukabije w'amaraso (Hypertension)
• Igipimo cy'isukari nyinshi mu maraso (`Hyperglycemia`)
• Kolesteroli nyinshi
• Indwara ya Metabolic Syndrome
• Kunywa itabi
• Umubyibuho ukabije
• Zimwe mu ndwara ziterwa n'ubwiyongere bw'umubiri

Ni izihe ndwara zindi zishobora guterwa no kudakora neza kw'imyanya y'imbere mu nda?

Iyi ndwara (Endothelial Dysfunction) yongera ibyago byo kurwara indwara z'umutima n'imitsi (Indwara z'umutima n'imitsi) n'izindi ndwara nyinshi. Urugero:

• Indwara ya atherosclerosis n'indwara y'imitsi ifata imitsi
• Amaraso apfutse hamwe n'indwara zo mu bwonko
• Umutima wagutse (Hypertrophic Cardiomyopathy)
• Indwara z'umutima n'indwara z'umutima
• Umuvuduko ukabije w'amaraso (Hypertension)
• Kunanirwa kw'impyiko
• Indwara y'imitsi yo mu mpande (PAD)
• Umuvuduko ukabije w'amaraso mu bihaha (PH)
• Indwara y'imitsi mito (Indwara y'imitsi mito y'amaraso)

Ni izihe ngorane ziterwa n'iyi ndwara?

Kudakora neza kw'imitsi yo mu nda bishobora gutera indwara yitwa Acute Coronary Syndrome . Iyi ni ubwoko butatu bw'indwara y'imitsi yo mu nda. Ibi byongera ibyago byo kuba ibinure byiyongera mu mitsi yo mu nda (plaque) mu maraso bikavunika. Uko gupfuka kw'imitsi bishobora kubuza amaraso gutembera mu mitsi y'umutima bigatuma umutima urwara.

Iyi ndwara ipimwa ite ? (Isuzuma)

Abaganga bakoresha ibizamini bitandukanye byo gufata amashusho kugira ngo barebe neza uburyo amaraso atembera mu mitsi y'amaraso. Ibi bizamini bishobora gufasha muganga kureba niba hari ibimenyetso by'imikorere mibi y'imyanya y'amaraso. Ibi bizamini birimo:

• Electrocardiogram (`Electrocardiogram - EKG`)
• Angiogramu, harimo na Coronary Computed Tomography Angiogramu (CCTA).

Nanone, ibizamini bimwe na bimwe bya "Stress Imaging" bishobora gukoreshwa kugira ngo harebwe niba amaraso atembera mu mitsi yawe yagabanutse, ibyo bikaba bishobora gutuma umutima wawe ukora cyane. Ingero:

• Echocardiogram (`Echocardiogram - echo`)
• MRI (`MRI`)
• Isuzuma rya Positron Emission Tomography (PET scan)

Ibi bivurwa bite? (Ubuvuzi)

Niba ufite indwara y'imitsi ifata umutima cyangwa iy'imitsi yo mu bwonko (COPD) bitewe n'imikorere mibi y'imitsi yo mu bwonko, muganga wawe ashobora kukwandikira imiti imwe n'imwe. Urugero:

• Asipirine cyangwa imiti igabanya amaraso.
• Imiti igenzura umuvuduko w'amaraso, nka calcium channel blockers.
• Imiti igabanya cholesterol nka statins.
• Imiti ifungura imiyoboro y'amaraso, nka nitrate.

Nanone, niba ufite ikibazo cyo kudakora neza kw'imyanya y'imbere (Endothelial Dysfunction), ushobora kugabanya ibimenyetso byawe ukoresheje guhindura imirire n'imibereho . Ibi birimo:

• Kurya indyo yuzuye umutima no gukora imyitozo ngororamubiri buri gihe.
• Kugabanya ikoreshwa ry'inzoga.
• Kugabanya ibiro (nibiba ngombwa) kandi ukomeze kugira ibiro byiza.
• Gushaka uburyo bwiza bwo gucunga imihangayiko .
• Shaka ubufasha bwo kureka kunywa itabi no kwirinda itabi ry'abandi.
• Kugenzura neza indwara nk'umuvuduko ukabije w'amaraso, diyabete, na cholesterol nyinshi.

Ni iki kizere cy’abantu bafite ikibazo cyo kudakora neza kw’imyanya y’imbere mu mubiri (Endothelial Disorder)?

Indwara yo mu nda ishobora kuvurwa hakoreshejwe uburyo bwo guhindura imibereho n'imiti.Ni indwara iravurwa cyane. Ariko, bamwe mu bantu bafite indwara y’imitsi y’umutima idakingiye (NOCAD) bashobora gukomeza kubabara mu gatuza nubwo bavurwa.

Ubu bwoko bw'ububabare budakira mu gatuza bushobora kubangamira imirimo ya buri munsi. Bushobora kandi gutera indwara nko guhangayika no kwiheba. Ubuvuzi bw'imitekerereze, imiti, n'uburyo bwo gucunga imihangayiko bishobora gufasha.

Ni ryari ngomba kujya kwa muganga?

Uramutse ubonye ibimenyetso bikurikira, hita ubonana na muganga:

• Kubabara mu gatuza
• Guhumeka bigoranye
• Ibimenyetso by'indwara y'umutima (urugero: kubabara cyane mu gituza, ububabare bugera mu kuboko kw'ibumoso, kubabara mu rwasaya, kubira ibyuya, isesemi)
• Umunaniro ukabije nta mpamvu

Ni iki ngomba kubaza muganga wanjye?

Ushobora kubaza muganga wawe ibibazo nk'ibi:

• Kuki nagize iyi ndwara (Endothelial Dysfunction)?
• Ese nkeneye imiti?
• Ni izihe mpinduka mu mibereho no mu mirire ngomba gukora?
• Ese mfite ibyago byo kurwara indwara z'umutima? Nagabanya nte ibyo byago?
• Ese nkwiye kumenya ibimenyetso by'ingorane?

Ubutumwa bwo kujyana mu rugo

Indwara yo mu nda iterwa no kudakora neza kw'imitsi y'amaraso ni ubwoko bw'indwara y'imitsi itera umutima gutera amaraso. Iyo nta nitric oxide ihagije ihari mu nkuta z'imitsi yawe, imitsi iragabanuka. Uku kugabanuka kugabanya amaraso atembera mu mutima. Iyi ndwara itera angina, cyangwa ububabare mu gituza, kandi yongera ibyago byo kurwara indwara z'umutima.

Ikintu cyiza ni uko, iyo ubibonye hakiri kare ukavurwa neza, ndetse ugahindura imibereho yawe, uba ufite amahirwe menshi yo kwirinda indwara zikomeye z'umutima. Kubwibyo, ntukirengagize ibimenyetso. Niba ushidikanya, ni byiza gushaka inama kwa muganga.
