Anthu ambiri amaganiza kuti magazi kuundana ndi chinthu choipa.
Kutsekeka kwa mitsempha ya ubongo ndi matenda a mtima kungayambitse sitiroko, kufooka kwa ziwalo kapena imfa yadzidzidzi mwa munthu wamoyo.
Zoonadi?
Ndipotu, magazi otuluka m'magazi ndi njira yachibadwa yolumikizira magazi m'thupi la munthu. Ngati magazi otuluka m'magazi satuluka m'magazi, anthu ambiri amafa chifukwa cha "kutaya magazi ambiri".
Aliyense wa ife wavulala ndipo watuluka magazi, monga kuvulala pang'ono m'thupi, komwe kudzatuluka magazi posachedwa. Koma thupi la munthu lidzadziteteza lokha. Pofuna kupewa kutuluka magazi mpaka imfa, magazi adzayamba kuuma pang'onopang'ono pamalo omwe magazi atuluka, ndiko kuti, magazi adzapanga magazi m'mitsempha yamagazi yomwe yawonongeka. Mwanjira imeneyi, magazi sadzatulukanso.
Pamene magazi asiya kutuluka, thupi lathu limasungunula pang'onopang'ono magaziwo, zomwe zimathandiza kuti magazi ayambe kuyenda bwino.
Njira yomwe imapanga thrombus imatchedwa njira yolumikizira magazi; njira yomwe imachotsa thrombus imatchedwa njira ya fibrinolytic. Mtsempha wamagazi ukawonongeka m'thupi la munthu, njira yolumikizira magazi imayatsidwa nthawi yomweyo kuti magazi asapitirire kutuluka; thrombus ikangoyamba, njira ya fibrinolytic yomwe imachotsa thrombus imayatsidwa kuti isungunule magazi.
Machitidwe awiriwa ndi ofanana, kuonetsetsa kuti magazi sakuundana kapena kutuluka magazi kwambiri.
Komabe, matenda ambiri amachititsa kuti magazi asagwire bwino ntchito, komanso kuwonongeka kwa intima ya mtsempha wamagazi, ndipo kukhazikika kwa magazi kungapangitse kuti magazi a fibrinolytic system asachedwe kapena asakwanitse kusungunula magazi.
Mwachitsanzo, mu matenda a mtima otchedwa acute myocardial infarction, pali thrombosis m'mitsempha yamagazi ya mtima. Mkhalidwe wa mitsempha yamagazi ndi woipa kwambiri, pali kuwonongeka kosiyanasiyana kwa intima, ndipo pali stenosis, pamodzi ndi kuima kwa magazi, palibe njira yosungunula thrombus, ndipo thrombus imangokulirakulira.
Mwachitsanzo, mwa anthu omwe amakhala pabedi kwa nthawi yayitali, magazi m'miyendo amakhala ochepa, mitsempha yamagazi imawonongeka, ndipo magazi amatuluka. Magazi amatulukabe, koma liwiro la kusungunuka silikwanira, limatha kugwa, kubwerera mu mitsempha yamagazi, kulowa mu mitsempha yamagazi, ndikuyambitsa pulmonary embolism, yomwe imaphanso.
Pa nthawiyi, kuti odwala akhale otetezeka, ndikofunikira kuchita opaleshoni yopangira thrombolysis ndi kubaya mankhwala omwe amagwiritsidwa ntchito polimbikitsa thrombolysis, monga "urokinase". Komabe, thrombolysis nthawi zambiri imafunika kuchitika mkati mwa nthawi yochepa ya thrombosis, monga mkati mwa maola 6. Ngati zitenga nthawi yayitali, sizingasungunuke. Ngati mugwiritsa ntchito mankhwala owonjezera thrombolytic panthawiyi, zingayambitse kutuluka magazi m'malo ena a thupi.
Thrombus singathe kusungunuka. Ngati sichinatsekedwe kwathunthu, "stent" ingagwiritsidwe ntchito "kukoka" mtsempha wamagazi wotsekeka kuti magazi ayende bwino.
Komabe, ngati mtsempha wamagazi watsekedwa kwa nthawi yayitali, izi zingayambitse ischemic necrosis ya ziwalo zofunika za minofu. Pakadali pano, ndi "kudutsa" mitsempha ina yamagazi yokha yomwe ingayambitsidwe "kuthirira" chidutswa ichi cha minofu chomwe chataya magazi ake.
Kutuluka magazi ndi kugayika kwa magazi, thrombosis ndi thrombolysis, ndi kulinganiza bwino komwe kumasunga ntchito za kagayidwe ka thupi m'thupi. Sikuti zokhazo, pali kulinganiza kwanzeru kwambiri m'thupi la munthu, monga mitsempha ya sympathetic ndi mitsempha ya vagus, kuti anthu azisangalala popanda kusangalala kwambiri; insulin ndi glucagon zimawongolera shuga m'magazi a anthu; calcitonin ndi parathyroid hormone zimawongolera calcium m'magazi a anthu.
Matenda osiyanasiyana akangolowa m'thupi, amayamba kuonekera. Matenda ambiri m'thupi la munthu amayamba chifukwa cha kutayika kwa mphamvu.
