Muhimmancin Maganar Myocardium
Tambaya: Mazan miji yana da nakasa na zuciya saboda cutar da ke dauke da cututtuka. Kwararren farko da muka gani ya gaya masa cewa yin gyaran tiyata ba zaiyi kyau ba saboda kullun da aka katange yana samar da tsoka tsohuwar da ta riga ya mutu. Amma likita na biyu ya ce yana yiwuwa zuciyar tsohuwar zuciya ba ta lalacewa ba har abada, amma kawai "ɓoyewa." Ya ce dawayin tiyata zai iya ƙyale tsoka ya "farka," kuma rashin tausayin zuciya ya inganta. Mene ne zaka iya fada mani game da tsohuwar zuciyar tsohuwar zuciya, kuma kuna tsammanin likitan na biyu zai iya zama daidai?
Amsa:
Babban mahimmanci game da "murkushewa na myocardium" (myocardium yana nufin tsohuwar zuciya) har yanzu yana da alama ga wasu likitoci, amma masu kwakwalwa suna sane da shi. A wasu mutane da cututtukan cututtuka (CAD) , wasu nau'ikan zuciya da suka kasance suna da mummunar lalacewa da rashin aiki sun kasance mai yiwuwa, kuma za'a iya "farfado" idan an sake dawo da jini.
An kiyasta cewa tsakanin 20 zuwa 50% na mutanen da ciwon zuciya na CAD suna da adadi mai yawa na murkushe myocardium, sabili da haka, suna da yiwuwar samun ingantaccen mahimmanci idan za'a iya mayar da jini ga muscle na zuciya.
Hanyar "Tsohon" ta Tunani game da Zuciya Mai Mutuwar Abinci
Maganin gargajiya na gargajiya bai bar dakin don irin wannan abu ba kamar na myocardium na hibernating.
Zuciyar zuciya tana aiki kullum muddan akwai isasshen jini. Idan jinin jini ya zama kasa don cika bukatun zuciyar tsoka (alal misali, lokacin da mutum da CAD fara farawa), tsoka ya zama abin ƙwaƙwalwa mai sauƙi (yunwa don oxygen), kuma angina zai iya faruwa.
Muscle zuciyar Ischemic ba ya aiki kullum. A gaskiya ma, yin aikin echocardiogram a lokacin motsa jiki shine hanya guda don gano zane-zane, tun lokacin da gwaji ya iya gani da sassan zuciyar tsohuwar da ba ta yin kwangila ko da yaushe idan aka hana su isasshen iskar oxygen.
Hanyar da likitocin suka yi game da CAD, ko dai dai ischemia zai tafi (saboda, alal misali, mutumin da ke tare da CAD zai daina yin amfani da shi lokacin da Angina ya fito), ko kuma ischemia zai ci gaba har sai zuciya ta zuciya (cututtuka na katsewa, ko mutuwar zuciya tsoka) ya faru.
Sabili da haka, maganin da ke dauke da magungunan ƙwayar cuta mai cututtuka zai iya zama a cikin ɗaya daga cikin jihohin uku: al'ada, ischemic, ko matattu.
Amma dai ya juya cewa tsokawar zuciya zai iya ci gaba a cikin jihohi na hudu, jihar da ake kira hibernation.
Mene ne Maocardium na Hibernating?
Maganar murya mai kama shi shine abin da yake sauti. Kamar yaduwar bore a cikin hunturu, duk da bayyanuwar tsohuwar zuciyar tsohuwar jiki ba ta mutu ba, amma dai dai ya zama matsayin "dormant". Ba ya daina aiki a al'ada - bana kwangila tare da kowace ƙwaƙwalwar zuciya, kuma baya taimakawa aikin zuciya.
Amma ba ya mutu. Abin sani kawai a cikin halin rashin tsaro na kai. Ya rufe dukkan ayyukan da ba shi da mahimmanci a rayuwarsa.
Zuciyar zuciya zai iya shiga cikin lalacewa lokacin da CAD ya daɗaɗɗa don samar da ischemia wanda yake ci gaba da daɗaɗɗa, maimakon mahimmanci da aka samo aschemia wanda ya zo kuma yana da sauki (wanda shine yanayin a mafi yawan mutane tare da angina). Saboda haka, ainihin, ƙwayar zuciya ba zata iya samun isasshen jini don aiki akai-akai, amma shine - kawai kawai - samun isasshen jini don ya kasance da rai.
Me yasa Maocardium Mai Cutar Hijira yana da mahimmanci?
Muscle zuciya mai ban sha'awa shine muhimmiyar mahimmanci saboda ƙwayar tsoka yana iya zama mai yiwuwa, kuma za a iya juyawa hibernation.
Idan za a iya dawo da jini na tsoka da ƙwayar tsoka - ta hanyar tafiya ko tiyata - akwai kyakkyawan damar da aka samu na myocardium zai iya "farka," kuma zai fara taimakawa ga aikin zuciya. A cikin mutumin da yake da ciwon zuciya , wannan ƙwarewar aiki na zuciya zai iya yin kowane bambanci.
A yanayin mijinka Ya zama kamar likita na biyu ya tabbatar da shaidar cewa mijinki yana iya yin ɓarna na myocardium, kuma yana bude ɗaya ko fiye da adadin jinji na jini da gyaran tiyata zai iya ƙyale wani ɓangare na ƙwayar zuciyarsa don fara aiki.
Akwai gwaje-gwaje na musamman waɗanda masu ilimin zuciya zasu iya yi don taimakawa wajen rarrabe maƙarƙashiya daga ƙwayar zuciya wanda ba zai iya yiwuwa ba (wato, mutu), ciki har da binciken MRI , da kuma gwaji na musamman na rubutun echocardiographic.
Layin Ƙasa
Tun da irin wannan jarabawar ba ta da haɗari kuma ba shi da hadarin gaske, neman yiwuwar yin amfani da myocardium zai zama daidai ne a yanayin mijinki.
Idan wannan kima ya nuna cewa yana iya samun adadi mai yawa na murkushe myocardium, sa'annan "farkawa" wannan ɓangare na tsoka da ƙwayar zuciya zai iya inganta yawancin zuciyarsa. Don haka zai zama mai mahimmanci don yin la'akari sosai da aikin tiyata wanda likitan zuciya yake bada shawara idan gwaji yana goyan bayan kasancewa na myocardium.
