Ua ntej cov ntshav oxygen-enriched nkag mus rau hauv cov hlwv ntawm sab laug thiab raug thawb mus rau hauv lub nraub qaum thiab lub voj voog loj, cov kua qaub nkag mus rau hauv lub plawv. Nws yog ib qhov kab mob plawv kab txuas nrog rau cov hlab ntsha hauv lub plhaub. Dilation ntawm sab laug atrium yog ib qho kev nthuav dav ntawm qhov muab lub chamber (ncab) tsis thim ntawm nws cov phab ntsa. Tus kab mob Pathology tsis yog ib qho kab mob uas tsis ywj pheej, vim nws tsuas yog ib qho kev mob ntawm tus kab mob hauv lub cev lossis mob kis.
Ua rau ntawm dilatation ntawm sab laug atrium
Lub hauv paus tseem ceeb tshaj plaws yog qhov ua rau kev txhim kho ntawm qhov teeb meem tau piav txog yog qhov nqaim ntawm lub mitral valve txuas rau cov hlwv thiab cov atrium. Vim yog lub qhov me me, cov ntshav tsis raug thawb thiab rov tuaj yeem rov qab mus rau lub chamber (regurgitation). Xws li cov overloads ua rau atrial dilatation.
Lwm yam ua tau ntawm kev loj ntawm lub plawv plawv nres:
- khov kho nce siab nyob rau hauv ib lub voj voog loj ntawm cov ntshav;
- hnyav lossis phij cuam ntawm cev nqaij daim tawv;
- aortic stenosis ;
- atrial fibrillation ntawm ntau cov ntaub ntawv;
- cardiomyopathy.
Thaj li, qhov kev xav hais tias mob qeeb ib txwm qhia tau hais tias mob plawv loj dua.
Cov tsos mob ntawm kev dilatation ntawm tus kab laug atrial laug
Cov tsos mob tshwj xeeb rau tus kab mob no tsis muaj nyob. Raws li txoj cai, ib tug neeg txhawj xeeb txog qhov tshwm sim ntawm qhov chaw tshwm sim ntawm qhov tseem ceeb ua rau kev loj hlob ntawm sab laug chamber ntawm lub plawv, thiab cov cim qhia ntawm lub plawv tsis ua hauj lwm.
Muaj qee qhov xwm txheej uas tus kab mob pathology no feem ntau asymptomatic (idiopathic dilatation). Nyob rau hauv xws li mob nws yog ib qho tseem ceeb rau kom ua tib zoo tshuaj xyuas thiab txawm li cas los xij nrhiav cov yam cuam tshuam los ntawm kev loj ntawm sab laug atrium. Feem ntau, cov kws kho plawv pib nrog rau kev haus cawv, vim haus dej cawv muaj nrog ntshav siab tas li. Yog tias thaum lub sij hawm txoj kev tshawb nrhiav qhov ua rau ntawm qhov tsis tu ncua, nws tseem pom zoo kom tsuas yog soj ntsuam xyuas tus mob thiab qhov loj ntawm lub plawv chwv.
Kev kho mob ntawm qhov chaw nyob ntawm sab laug atrium
Muab hais tias qhov nthuav ntawm cov kab noj hniav ua tau piv rau ib qho kev mob tshwm sim, tsis yog muaj kab mob, kev kho raws li kev tshem tawm cov kab mob pathology uas tsim teeb meem. Tsuas yog tom qab no nws tuaj yeem npaj mus rau qhov kev kho mob tam sim ntawd ntawm cov lus piav qhia, yog tias nws tseem xav tau. Thaum muaj ntshav txaus lawm rov qab los, cov ntshav siab tuaj yeem ua rau lub cev thiab lub zog ntawm qhov vas sab zoo, qhov ntim ntawm lub plawv nres rov qab rau qhov qub. Lub elasticity ntawm nws cov phab ntsa kuj tseem yog tib yam.
Cov menyuam yaus nyob hauv plawv tshuav tsawg feem ntau tsis raug rau kev kho, xws li hauv cov ntaub ntawv nrog daim ntawv idiopathic ntawm tus kab mob no, hauv qhov xwm txheej no, kev saib xyuas thiab kev kaw suab ntawm qhov ntim ntawm tus kabmob plawv yog nqa tawm.
Nrog rau sim dilatation ntawm sab laug atrium ntawm 1-2 degree ntawm kev pom zoo ntawm cov kws kho plawv, ntau cov tshuaj yuav qhia:
- antagonists ntawm aldosterone;
- diuretics ;
- tshuaj antiarrhythmic;
- mob plab glycosides;
- beta-blockers;
- antiaggregants;
- ACE inhibitors.
Qhov tsim nyog ntawm kev siv, kev siv tshuaj thiab kev txais tos ntev npaum li cas los ntawm tus kws kho mob ntawm tus neeg ntawd rau txhua tus neeg.
Ntxiv nrog rau kev siv tshuaj kho mob, kev kho mob uas tsis yog pharmacological yuav tsum tau txhaj. Nws muaj cov tswv yim nram no:
- Ua kom tiav cov dej cawv los ntawm kev noj haus.
- Txo cov kua qaug cawv txhua hnub.
- Xaiv ib qho kev ua si ntawm lub cev.
- Txwv tsis pub noj cov zaub mov uas ua rau kom ntshav ntws ntau dua.
- Saib xyuas ntshav siab.
