Sayenzi yezvokurapa yakave ichiziva kuti kusara kwekugara shure kweS ST Segment Elevation Myocardial Infarction (STEMI) (kurwisa kwemwoyo) ndicho chikuru chinokonzera kufa kwekutanga. Vanhu vanoita zvirongwa zvekugadziriswa kwepfungwa mushure mekurwa kwepfungwa, uye vozoenderera mberi kudzidzira kana chirongwa chemaitiro chaiwo chapera, vanozivikanwa kuti vanoita zviri nani kwenguva yakareba kupfuura vanhu vanoramba (kana kuva) vasina basa.
Ichi ndicho chikonzero chekuita muviri nguva dzose kunosimbiswa navanachiremba vanoporesa varwere vane chirwere chegoni (CAD) .
Pfungwa yokuti panogona kuva chinhu chakadai se "kuwandisa" gadziriro mushure mokunge chirwere chemwoyo chiri chitsva. Kana kuti, ihwo hutsva hutsva hwepfungwa yekare-makore makumi mashanu apfuura moyo wevarwere vakaurayiwa vaigara vachirapwa nemavhiki ekurara, uye semugumisiro kazhinji vakava vasina simba rekusingaperi. Kuti pangava nechinhu chakadai sekurovedza muviri zvakanyanya mushure mekurwa kwepfungwa kwakamutswa patsva nepeji yekutsvakurudza inoonekwa muna August 2014 muMayo Clinical Proceedings . Iyi pepa inoratidza kuti, kana nguva dzose yekuvhima mushure mokunge chirwere chepfungwa chinopedza uye chinonyanya kuderedza ngozi yekufa, zvinobatsira zvekurovedza muviri zvingatanga kuchinja kana imwe chikumbaridzo ichisvika.
Kunyanya, vanyori vanoti, vanopukunyuka pamwoyo vanomhanya kupfuura makiromita makumi maviri nevhiki, kana vanofamba zvishoma kune anenge 46 mairasi pavhiki, vane ngozi yakawanda yekufa kune vanomhanya (kana kuti vanofamba) vanoita zvishomanana kupfuura izvozvi .

Uchapupu hweKuedza Kudzivirira
Icho uchapupu hunobva kuNational Runners 'Health Study uye National Walkers' Health Study. Zvidzidzo izvi zvakanyorerwa vanopfuura 100 000 vatori vechikamu, avo vakazadza mutsamba dzemibvunzo inotsvaga pamusoro pezvakaitika kare mune zvezvokurapa uye maitiro ekurovedza muviri.
Pakati pevatori vechikamu izvi, varume vanosvika 924 uye 631 vakadzi vanotaura kuti vaiva nekutambudzika kwemoyo, uye ava ndivo vanhu vakabatanidzwa muchidzidzo chatiri kukurukura.
Hezvino izvo vakaongorora vakawana. Mushure mokunge vateverwa kwemakore anenge gumi, vatori vechikamu avo vakamhanyira kusvika makiromita masere pavhiki kana kufamba kusvika makiromita makumi maviri nevhiki (iyo inenge iri kure iyo munhu aizowana ivo vanotevera mafungiro emapurisa ekurwisa maitiro ), vakaderedza chirwere chemwoyo yavo -kubatana nehuwandu ne21%, zvichienzaniswa nevanenge vari vapenyu vanoparara mwoyo. Kufa kwakaderedzwa ne24% kune vanhu vaimhanya makiromita 8 kusvika ku16 kana kufamba makiromita 12 kusvika ku3; ne50% kune avo vakamhanya makiromita makumi mapfumbamwe nemaviri kana kufamba maira 23-34 maira pavhiki; uye ne 63% kune vanhu vaitamba makiromita 24 kusvika ku-31 kana kufamba 34-46 maira pavhiki.
Zvisinei, muvanopukunyuka pamwoyo avo vakanyanyisa kuita basa ravo, kusvika pakuti ivo vakamhanyisa makiromita anopfuura makumi matatu kana kufamba kupfuura makiromita makumi mana nevhiki, chete kupera kwe12% kwekufa kwakaratidzwa-iyo inenge hafu yezvakabatsirika yakawanikwa vanhu "vanongotevera" vakatevedza ikozvino maitiro emitemo. Saka, kubva padzidzo iyi, zvinoratidzika kuti kunyanya kushandisa kwaunoita mushure mekurwa kwepfungwa kunobatsira zvikuru - kusvika pane imwe pfungwa. Asi kunze kwechinhu ichocho - kana chiito chinoratidzirwa chiito chinosvika - kufa kwekubatsira kwebasa rinotanga kuchinja.
Vanyori vehurukuro inoratidzika mumagazini imwechete yeMayo Clinical Proceedings vakafungidzira kuti zvimwe pane chinhu chakadai se "kuora mwoyo kwepfungwa," umo kurovedza muviri kwakanyanya kunogona kuderedza hutano hwepfungwa (zvichida nokubudisa ruvara rwehutu mumoyo uye saka chirwere chemoyo ). Kana zvakadaro, ipapo pane zvingava zvechokwadi chinhu chakadai se "kuwandisa" basa, kunyanya kune vanhu vakave nekurwadziwa kwemoyo.
Ichokwadi Izvi Ichokwadi Here?
Zvingave zvechokwadi ndezvechokwadi kuti kuita "zvakanyanya" maitiro mushure mekurwa kwepfungwa kunogona kubhadhara zvakawanda zvekubatsirwa kwaunowana kuburikidza nekuita muviri wose. Zvisinei, kune zvikakosha zvakakosha zvekudzidza uku kunoda kuti isu tiise maonero ayo muone.
Kutanga, chidzidzo ichi chaitwa nemibvunzo yemibvunzo chete. Tinofanira kutora shoko revatori vechikamu kwehuwandu hwemashandiro avakaita, uye zvichida kunyanya kukosha, nokuti ivo chaizvoizvo vakave nekurwadziwa kwemoyo. (Vanachiremba dzimwe nguva vanoshandisa izwi rokuti "mwoyo kurwisa" vasingatauri uye asingatauri, uye varwere vavo vanogona kuuya vachifunga zvisina kukodzera.) Saka pane imwe nhanho, kururama kwe data pachako kungabvunzwa. Izvi, zvechokwadi, zvinokonzerwa nekudzivirira kwechipi nechipi chekurapa chinongoraramira chete pamibvunzo yeiyo yezvinyorwa zvayo.
Zvimwe zvinokosha zvakanyanya ndekuwanikwa kunowanikwa apo munhu anoona tafura yemashoko yakabudiswa neshoko racho pacharo. Kubva patafura iyo, zvinoratidzika kuti vapukunyuka pamwoyo avo vanomhanya kupfuura makiromita makumi matatu pavhiki, paavhareji, vakawanda kupfuura vaduku vanomhanya zvishoma. Muzvokwadi, ivo vaive nemakore makumi mashanu chete. Uyezve, zviri pachena kuti vakave nemoyo yavo inorwisa mushure mekunge makore gumi nemaviri vasati vanyoresa muchidzidzo ichi, kana (pamwero wega) pazera remakore makumi matatu nemana. Vanyori venyaya yacho havatauri zvakananga zvinorehwa nezera iri.
Asi isu tinoziva kuti vanhu vane mwoyo inorwisa vachiri vaduku vanowanzova nehuwandu hwechikwata cheCAD, uye chirwere chemoyo wavo chinogona kuva chinowedzera uye chinorema kuporesa kune vanowanzoita varwere vane CAD. Saka, zvichida kuwedzera kwekufa kwakaonekwa kune vanhu vakamhanya kupfuura makiromita makumi matatu nevhiki paisina kubatanidzwa nechiito zvachose. Panzvimbo pacho, zvichida izvi zvaingova hupenyu hwakasiyana hwevarwere varwere.
The Bottom Line
Musoro wehurukuro wakaparidzirwa zvikuru nekuda kwekudzidza uku unoti "Kuita zvekurovedza zvakanyanya mushure mekurwa kwepfungwa kunogona kukuuraya!" Kunyange zvazvo zvingava zvechokwadi kuti kuita zvakanyanyisa kubata mushure mekurwa kwepfungwa kunogona kubhadhara zvinobatsira zvemuitiro , isu Tinofanira kuchengeta zvinhu zvishomanana mupfungwa sezvatinofunga pamusoro pezvinenge zvichinyatsoreva chidzidzo ichi.
Chokutanga, chidzidzo ichi hachiratidzi chinhu; hazvina kukwana kudzidza kuti uite chimwe chinhu kunze kwekuti upe hutano hutsva hunoda kuongororwa mune zvinotarisira zvipatara.
Chechipiri, "chidziro chekudzidzira" icho chakanga chakaonekwa muchidzidzo ichi, kunze kwekuti chiito chinogona kuve chakakuvadza mushure mekurwadziwa kwepfungwa, yakanyanya kunyanya. Chero ani ari kumhanya makiromita anopfuura makumi matatu nemashanu kana kufamba kune makiromita makumi mana nevhiki pave pangangodaro akagadzirisa hupenyu hwavo hwose pavanenge vachiita maitiro avo. Vapukunyuka vashomanana vekurwadziwa kwemoyo vanogara vachiita pose pose pedyo nepamusoro apo pane chikonzero chekufunganya.
Uye zvinonyanya kukosha, pasinei nokuti pane chinhu chakadai se "kuwandisa" chiito mushure mekurwa kwepfungwa, ichi chidzidzo chinopupurirazve zvakare kuti nguva dzose yekurovedza mushure mekurwa kwepfungwa - kunyange maitiro ekurovedza zvikuru moyo wekushungurudzika kwepfungwa vanenge vasati vamboedza kuchengeta - yakabatana nekuvandudzwa kwakanyanya mumigumisiro yemoyo. Kudzidzira nguva dzose, ichi chidzidzo chinosimbisa, chinonyanya kukosha kuhutano hwako mushure mekurwa kwemoyo.
