Iti hoki iaia

puta iti hoki iaia i roto i pā ana ki 1-2% o te taupori katoa. Ko nga wa katoa te āhua taua te putanga o tetahi mate. I roto i te nuinga o te wā, arata'i te reira ki mate o te Cardiovascular pūnaha. Ko ētahi o ēnei cardiomyopathy, angina, infarction myocardial, mea kohakore ngakau.

Ko te hinganga o te uaua ngakau pāngia e takahi o te supply toto ki te tinana, e tika ana ki tona vaivai me te mahi ta'efakafiemālie o tona mahi köurarangi.

āhuatanga iti hoki iaia te rite te huru pathological i roto i nei i reira ko te hekenga i roto i te tonus o te uaua maeneene o te taiepa oko. whakaoho tenei hypotension, te ngangau i roto i te hoki venous me te rere o te toto.

iti hoki iaia e tika ana ki pāpaka tuatahi āhua o te kore ngakau tahi i te okana, me oko tauhohenga mooni. āhuatanga tēnei tauhohenga e te natura e vai. Ko te kupu whakapeka iti hoki iaia manawa haere tahi i te tauhohenga, whakakitea nei i roto i te puka o te vasoconstriction i whakautu ki te pānga o tikanga pressor. arata'i tenei ki te hua i roto i te resistance iaia mo te tetahi wā, etahi hua i roto i te taumata o te pēhanga toto me te māori o te supply toto ki whēkau nui o te ora. I roto i te huru whakakapi vasoconstriction ma'i mai hypertrophy o ngā pūtau uaua maeneene o te taiepa oko.

Ki te kēkeno o te tikanga e vai i roto i te kore te ngakau, hono iti hoki iaia. te whakaiti i tenei te ātete piringa katoa, tino whakawhänui te iti uaua, venules me tōiti.

Tata ki te tukanga katoa i roto i nei kua te ngakau mahi kauwhau hoki te wa roa, kino hanganga tupu i roto i te myocardium, e whakaoho ana i te kore o te ngakau, me te oko ranei. Ka rite ki whakaaturanga mahi, maha kitea te āhua i runga i te whakamārama o taua mate rite te mate coronary iatuku, mate ngakau valvular (riro me congenital), myocarditis, mana hypertensive, cardiomyopathy. I tua atu, kia puta te mate i roto i mate o pāpaka pūkoro endocrine āhua, iti kai tōtika.

Ko te take tino auau o te mate (80% take) i roto i te mate Cardiovascular he mate te AVC.

Ki te mate e taea arahi ngā take. Mataotao e toru ngā rōpū matua o ngā āhuatanga etiological.

Ko te rōpū tuatahi ngā āhuatanga e whai he pānga totohu tika i runga i te myocardium. Te reira i taea e whētuki tinana, te rongo matū (hei tauira, tarukino tuwhena rawa). I tua atu, tika pānga e totohu taea, me ngā āhuatanga koiora (tāoke, tukumate, pirinoa).

Ko te rōpū tuarua o ngā take ngā te āhuatanga e whakapataritari he kikī o huru mahi myocardial. Ko ētahi o ēnei he hua nui i roto i te rōrahi o te toto taumai ki te ngakau ( "kaha kikī"). kia puta tenei iti hoki, ka cardiac piha, aroaro extracardiac me intracardiac shunts, a i roto i te hypovolemia. kikī me take myocardial ake i roto i ātete ki runga ki pana i te kōhao o te toto ngakau ( "kikī pēhanga"). I roto i tenei take, whakawhanake kore Cardiovascular i roto i te aroaro o te hypertrophy myocardial. Me kï reira e puta hypertrophy i te tari tinana, e te mauria atu te mahi kaha.

Na te toru o nga rōpū ngā nga āhuatanga e whakaawe te waimaero whakakī ventricular diastolic. meinga ana tēnei huru e te hekenga ki te whānuitanga nui te rōrahi toto komuhumuhu (i roto i te ru kaha ranei toto mate), me te takahi i roto i te te whakangā diastolic o te ngakau i roto i te kōpeketanga o tona wai i piki i roto i te pericardium (toto, transudate, exudate).
