Angina inoreva zviratidzo (kazhinji kurwadziwa kwechifuva kana chifu chisina kunaka) chinobudiswa neIschemia chechikamu chemuviri wemwoyo - ndiko kuti, kana musikana wemwoyo usingagamuchiri okisijeni yakakwana. Chikonzero chinonyanya kukosha chengeni chinonzi coronary artery disease (CAD) .
Chii Chine Utsi Angina?
Apo chiremba anoita kuti aongororwe angina, danho rinotevera nderokuona kana iri "yakasimba" kana "isina kugadzikana" angina.
Angina isina kugadzikana - umo zviratidzo zvinowanzoitika pazororo, kana nekuedza kusina zvishoma, kana neshamwari dzisina kujairika - kazhinji chimiro chechirwere chinonzi acon coronary syndrome , uye inofanira kuonekwa sechirwere chekukurumidzira. Angina isina kugadzikana inokonzerwa nekuputika mune imwe nzvimbo ye atherosclerotic .
Nenzira yakanaka, vanhu vazhinji vane CAD vane chinyorwa angina .
Angina yakasimba inokonzerwa nedanda rakasimbiswa risina kuputika, asi pane kubudisa kusagadzikana, kusagadzikana kwakagadziriswa mumutambo wegononi. Izvi zvinowanzovhara ropa rinokwana kusvika pamwoyo musumbu panguva yekuzorora, saka pakuzorora hakuna angina. Kunyange zvakadaro, kuvhara kwechidimbu kunopedzawo kuwedzerwa kweropa kudarika iyo ariti inokwanisa kupa. Saka, dzimwe nguva apo musikana wemwoyo unoda kushanda zvakaoma, zvakadai panguva yekuedza muviri kana kushungurudzika mupfungwa, ropa rinogona kuwedzera zvakaringana kuti riwane zvinowedzera zvido pamwoyo wemisungo.
Iyo musikisi-inoshaya nzara inova ischemic, uye angina inoitika.
Kana imwe nguva muviri uchimiswa - zvichida nokuti murwere anotanga kutarisa angina - oxygen inodiwa nemwoyo yemisumbu inodonha kusvika kune imwe yero yekutanga. Mumaminitsi mashomanana, ischemia inogadzirisa uye angina anoenda.
Mamiriro eStable Angina
Varwere vane anina akachengetedza kazhinji havana zviratidzo zvachose pavanenge vachizorora kana panguva yebasa rakanyorova, sezvo ropa richiyerera kumwoyo yavo misungo yakakwana pasi pemamiriro aya.
Angina inowanzoitika nekushingaira, uye kazhinji nenzira isina kukwana uye inofanirwa kuitika. Semuenzaniso, munhu ane angina akachengetedza angaona zviratidzo apo kana achikwira chikwata chechipiri chekufamba, kana kuti mushure mokufamba kupfuura zvitatu mabheji.
Nemhaka yekuti angina yakasimba inowedzera kuwanikwa, vanachiremba vanowanzoshandisa kushungurudzika kwepfungwa kuti vaite kuongororwa kwakaoma kwehuwandu hwekuvharidzira huchigadzirwa nechinangwa chekuita. Angina iyo inowanikwa mushure memasekondi makumi matatu pamutsetse wepamusoro inogona kukonzerwa nechepiti iri kuunza kuvhara kwakawanda. Kana iyo angina inowanikwa mushure memaminitsi gumi, chiyero chekuvhara ropa chinogona kunge chisina kuoma.
Saizvozvowo, kuongororwa kwepfungwa kunoshandiswa kunogona kushandiswa kutonga kukwana kwekurapa, uye kupa murwere chimwe chikonzero chekushingaira kwavanogona kuita pasina mwoyo wechem ischemia.
Kurapa Simba Angina
Chinangwa mukurapa angina chakachengetwa chinowanikwa katatu: kubvisa kana kuderedza zviratidzo zve angina, kuedza kudzivirira kupfuurira mberi kweatrosclerotic plaques, uye kuedza kudzivirira mhirizhonga yakawanda yeCAD - iyo, myocardial infarction , moyo kusakwanisa , uye rufu.
Mushonga unodiwa kuti uite zvinangwa izvi unogona kuva wakaoma, uye unowanzobatanidza kuita sarudzo dzekurapa.
Ani zvake ane angina anoda kunzwisisa zvinhu zvakabatanidzwa pakuita izvi zvisarudzo.
