Ndeipi nzira yakarurama yekuwana chirwere chetachiona chirwere?
Kuongorora hutachiona hwehutano (CAD) kunogona kuva dambudziko kune vose varwere uye vanachiremba vavo nokuti pane vanhu vakawanda vari pangozi yeCAD uye yakawanda miedzo inogona kushandiswa. Ndiani anofanira kuongororwa, uye ndeipi miedzo inofanira kuva nayo?
Chii CAD?
CAD chirwere chisingagumi chearononic artery . Mune CAD, atherosclerosis inokonzera kushanduka, kutonhora kwemaarteri kuti ave akaomeswa, kuomeswa uye kuvhiringidzwa ne " plaques ," iyo inoshandiswa ne calcium, mafuta, uye masero asina kuvhiringidza masero.
Izvi zvinogona kupindira mumugwagwa we arteri, zvichiita kuti kuvhara kweropa kudengenye, izvo zvinowanzokonzera angina . Miti yacho inogonawo kukurumidza kuparara, zvichiita kuti ropa rive neropa kuti riite acly mukati megoni inogadzirisa iyo inokonzera kuvhara ropa kamwe kamwe. Zvizhinji zvinokonzera myocardial zvirwere ( kurwadziwa kwemoyo ) zvinokonzerwa nekuputika kwepakiti.
CAD chirwere chisingagumi, chinopfuurira chinowanzovapo kwemakore mazhinji munhu asati aziva kuti pane chakaipa. Kazhinji kacho, chiratidzo chekutanga chekuti pane dambudziko nderimwe apo chiitiko chisingaregereki chinowanzoitika, chakadai sechirwere chemyocardial kana kusungwa kwemwoyo . Izvi zvinoreva kuti kana iwe uri pangozi yakawanda yeCAD, haufaniri kumirira zviratidzo zvirikukura usati waona kana une dambudziko.
Kuongororwa CAD
Kuziva "Zvinokosha" Blockages
Mutsika, kuongororwa kweCAD kwakatsigira kuongororwa kunotsvaka hupupuriro hwe "zvakakosha" mumaketari emakoronary .
(Kazhinji, cardiologists inofunga nezvekukosha "kudzivirira" kuti ive imwe inodzivisa 70% kana kupfuura imwe yeriti yetiri.)
Kudzidzira kuedza (kana kupindira kuongorora ) kunowanzobatsira pakutsvaga chikamu chakavharidzirwa mishonga yerononi. Kudzora kudzvinyirira kunetseka kunowanzobudisa zviratidzo zvema angina uye maitiro ekuchinja pane electrocardiogram (ECG) - zvinowanikwa zvinonyatsoratidza kuti mabheji aripo.
Verenga Nezvekutambudzika Kwepfungwa
Kuita kuongororwa kwepfungwa pamwe chete ne thallium / Cardiolite kudzidza kana echocardiogram inovandudza kukwanisa kuwana zvishoma zvakadzivirirwa aronary arteries. Thallium neCardiolite vane radioactive zvinhu izvo zvakakonzerwa muvhesi panguva yekurovedza muviri. Zvinhu izvi zvinotakurwa kumutsipa wemwoyo nemarrotonary arteries , nokudaro zvichibvumira mwoyo kufungidzirwa nekamera yakakosha. Kana imwe kana akawanda emakironari emakoroni akavharwa zvishoma, nzvimbo dzemuviri yemutsipa dzinopiwa nemaroto aya dzinoratidzika pamusoro pechifananidzo sematema. Echocardiogram inogadzira mufananidzo wemoyo unorova uchishandisa mafungu emhepo. Chero kusanganisa kusina kuchena mumutsipa wemwoyo kunoonekwa pa echocardiogram munguva yekuvhiya inoratidza CAD.
Verenga nezve thallium / Cardiolite kuongorora uye echocardiograms
Kana kuongororwa kwepfungwa kunonyatsoratidza kuti rimwe kana kuti mamwe mabheji aripo, varwere kazhinji vanotumidzwa kuti catheterization yemwoyo . Chinangwa che catheterization ndechokujekesa zvizere nzvimbo uye huwandu hwezvose zvinogadzirisa arteri blockages , kazhinji nokuda kwechinangwa chengioplasty , kunyorera kana kupfurikidza nekuvhiyiwa .
Verenga Nezve Cardiac Catheterization
Nzira dzisiri dzisina kuwanikwa dzinove dzichigadziridzwa dzinogona kuchinja chimwe chikonzero chekushaya catheterization yemwoyo.
Izvi zvinosanganisira CT scan multislice uye MRI yemwoyo . Zvinosuruvarisa, hapana imwe yenzira idzi nhasi inogona kudzokorora zvachose chido chekushaya catheterization .
Kuziva Mabheti Asina Kuita Zvibato Zvikuru
Mumakore achangobva kupfuura, vanodzidza nezvemapurisa vakaziva kuti zvose zvinokanganisa myocardial uye angina isina kugadzikana zvinokonzerwa nokuputika kwemavara mumaroto e coronary . Icho chinotarisa kuti mune zvakawanda kana zvisingazoitiki, mapapiro ayo anoguma kubviswa angadai akaonekwa se "asingasviki" (kureva,, kwete kukonzera kubviswa kukuru) vasati vapera. Ichi ndicho chikonzero tinowanzonzwa pamusoro pevanhu vane chirwere chemwoyo nguva pfupi mushure mekunge vaudzwa kuti havana CAD inokosha.
(Izvi zvakaitika kune mutori wenhau weTV Tim Russert muna 2008.)
Sezvo chero chinhu chipi zvacho chinogona kuparara, zvinobatsira kuziva kana mapepa aripo - kunyange maduku. Vanhu vane zviyero zvese zveCAD vanofanira kutora matanho ekugadzirisa zvikwangwani uye kuderedza dambudziko rekuparara kwemavara . (Matanho akadaro anowanzobatanidza ngozi yekutengesa, mararamiro ekuchinja, statins , uye aspirin.)
Kuongorora kweCalcium kuri kuitika senzira inobatsira yekuona kuvepo kwechidiki cheCAD. Kuongorora kweCalcium inzira yeTCT scanning iyo inogona kuvharidza huwandu hwema calcium inowanikwa mumaketari e coronary . Sezvo calcium inowanzoitika inowanikwa mumataundi, kuenzanisa kuwanda kwemaricisi mumitambo inoburitsa zvinoratidza kana CAD (uye naizvozvo mabhokisi) aripo uye kuti CAD yakawanda sei. Nokukukurudzira kuti iwe unenge uine CAD yakakwana yekubudisa "silent" plaques, calcium scan ingakupa mukana wekuchinja mararamiro ako, uye zvichida kutora mishonga yakakodzera, muchiri nguva yekuita.
