Ischemia mamiriro ezvinhu umo hauna kukwana kwekuyerera kweropa kune imwe yenhengo dzomuviri, kazhinji dzinokonzerwa ne- atherosclerotic plaque muyiti inopa chimiro. Nhengo inotungamirirwa neIschemia inonzi inonzi ischemic .
Nemhaka yekuti chimiro cheschemic hachigamuchiri okisijeni uye michero inenge ichida, ischemia inowanzotadzisa nhengo inobatwa nayo kusashanda, uye kazhinji, kubudisa zviratidzo.
Kana iyo ischemia ikava yakaoma zvakakwana kana inoramba ichireba kwenguva yakareba, masero ehutachiona anotarisana anogona kutanga kufa. Rufu rwezvose kana rutivi rwechigadzirwa chesicic rinonzi infarction .
Mienzaniso inowanika yeIschemia inosanganisira zvinotevera:
Cardiac Ischemia
Cardiac ischemia inonyanya kunokonzerwa ne atherosclerotic plaques mumaroto e coronary , arteri inopa moyo musumbu. Zvisinei, chirwere chinonzi cardiac ischemia chinogonawo kubva kune dzimwe mamiriro ezvinhu akadai sokugadzirisa arteri spasm , chirwere chemwoyo X , kana congenital anomalies yemakoronary arteries .
"Chimiro" chinonzi "angina" chiratidzo chechipfuva (kana muviri wepamusoro) kusagadzikana kunokonzerwa nemwoyo yechemical ischemia inopedzerwa nekurovedza muviri kana kushungurudzika. Zviratidzo zvinowanzova nerunyararo kana zororo.
"Atypical" angina, kana kuti angina isina kugadzikana , kazhinji inowanikwa pasina hukama hwekuita zvepabonde kana kushungurudzika uye kazhinji inowanzoonekwa neaconary syndrome yakaoma - chirwere chekukurumidzira.
Ubongo Ischemia
Utano hwebongo hunoshandiswa nehutachiona hunoshingaira, uye kuitira kuti hushande zvakanaka, uropi hunogamuchira 20% yeropa inoputirwa nemoyo. Uyezve, kusiyana nedzimwe nhengo dzakawanda uropi hadzina magetsi ezvayo, uye zvakanyatsotarisana nekuenderera kweropa kutevera basa racho. Nekudaro, hutachiona hwehurosi huchikurumidza kuva ischemic kana kubuda kweropa kuchivhiringidzika, uye kunze kwokunge ropa richiyerera rinodzorerwa nokukurumidza muuropi rufu nokukurumidza inosvika.
Rufu rwehupi hutachiona hunonzi sitiroko .
Dzimwe nguva ropa rinopinda kune chikamu cheuropi rinoparadzaniswa kwenguva yakakwana kuti ribudise zviratidzo zveuropi ischemia, asi kwete kwenguva yakakwana yekubereka chirwere chaiyo. Ichi chiitiko chinonzi "kurwisa kwechirongwa chekupedzisira" (TIA) . A TIA inogona kudhinda chero yemhando dzakasiyana-siyana dzechirwere chechirwere - kunze kwekuti zviratidzo zvinogadzirisa mukati maawa mashoma. TIA inokosha kwete kwete chete nokuti inotyisa mukati mavo, asiwo nokuti inowanzoteverwa nesitiroyo yakazara. Nokudaro, TIA inogara ichida kurapwa nokukurumidza.
Intestinal Ischemia
Utachiona ischemia (inonziwo maenteric ischemia) inowanikwa nehosha mukati memidziyo yeropa inopa nhengo dzomuviri.
Chirwere chepachiviri chinonzi ischemia, icho chinowanzobudiswa ne atherosclerosis yemakumbo emakumbo, inowanzokonzera zviratidzo zvinowanzoitika mushure mekudya, apo matumbu ari kuedza kuita basa ravo rekudya mukati mekutarisana kwekuwedzerwa ropa. Utachiona ischemia inowanzokonzera marwadzo emimba (anonzi maruva angina) mushure mekudya, kunyanya kudya kwemafuta. Utumbo hwemakumbo chirwere chisina kunaka uye chinoputika pedyo negomba remukati, kunyange chinogona kupenya kumashure.
Majoka emakumbo anowanzopfuurira kwemaawa anenge maviri, asi anodzoka mushure mekudya kumwe.
Yakanyanya intestinal ischemia inogona kuitika apo kubatana (blood clot) kunogara mumatumbo emumakumbo. Aya mavhavha eropa anowanzobva mumoyo, semugumisiro weheyriyumu fibrillation. Kana kubumbism yakanyanya kukwana, mukati mamapiritete (kufa kwechikamu chemukati) kunogona kuguma. Intestinal infarction chirwere chekukurumidzira.
Limb Ischemia
Ischemia yemakumbo inogona kuitika nehutachiona hwehutano (PAD), maitiro e atherosclerosis anokanganisa arteri inopa maoko kana makumbo (kazhinji, makumbo).
Chirwere chinowanzoonekwa nechiso ischemia inonzi claudication , chirwere chekurwadziwa, chinowanzokonzera gumbo rimwe, rinowanzobereka chibereko mushure mekuda kwekufamba. PAD inowanzobatwa ne angioplasty uye inopisa , kunyange kupfurikidza nekuvhiyiwa kunowanzodiwa.
