A transmural MI yog cim los ntawm ischemic necrosis ntawm tag nrho cov tuab ntawm qhov cuam tshuam cov nqaij ntshiv (s), nthuav tawm los ntawm endocardium los ntawm myocardium mus rau epicardium.
Ntawm no, dab tsi yog transmural infarction?
A transmural mob plawv infarction hais txog myocardial infarction uas suav nrog tag nrho cov tuab ntawm myocardium. Nws yog ib tus ntseeg tias kev txhim kho Q nthwv dej qhia txog qhov infarction yog transmural ;” txawm li cas los xij, kev tshawb fawb lub cev tsis ua haujlwm kom paub tseeb qhov no.
Tom qab ntawd, lo lus nug yog, puas inferior infarct txaus ntshai? Kev kwv yees. Thaum qis dua phab ntsa MIs ib txwm muaj qhov tshwm sim zoo, muaj qee qhov xwm txheej uas yuav ua rau kom tuag taus. Kwv yees li 40% ntawm qis dua phab ntsa infarctions kuj koom nrog txoj cai ventricle. Txoj hlab ntshav sab xis yog qhov ua ntej thauj khoom ntau, thiab nitrates tuaj yeem ua rau cov ntshav ntshav poob qis.
Ib tus kuj tseem yuav nug, qhov sib txawv ntawm kev kis kab mob thiab subendocardial infarction yog dab tsi?
Tias yog vim li cas subendocardial infarction kuj tseem hu ua non-ST-elevation myocardial infarction (NSTEMI) thiab tsawg dua uas tsis yog-Q yoj myocardial infarction . Hauv transmural MI, ischemia hauv subendocardium kis mus rau epicardium thiab cuam tshuam tag nrho cov tuab ntawm myocardium.
5 yam mob myocardial infarction yog dab tsi?
Tsib hom mob hnyav MI sau tsib qhov xwm txheej sib cais uas ua rau myocardial ischemia thiab myocardial-cell tuag:
- Thawj qhov xwm txheej mob plawv, xws li cov quav hniav tawg lossis phais.
- Ib qho teeb meem ntawm cov pa oxygen thiab xav tau, xws li mob hlab ntsha tawg, mob hlab ntsha hauv lub plawv, mob plawv tsis ua haujlwm, ntshav tsis txaus, lossis mob ntshav siab.

Yuav kuaj tus mob myocardial infarction li cas?
Kev kuaj mob ntawm myocardial infarction yog tsim los ntawm kev suav nrog keeb kwm ntawm kev mob tshwm sim thiab kev tshuaj xyuas lub cev nrog kev tshawb pom electrocardiogram thiab ntsuas lub plawv (ntsuas ntshav rau lub plawv mob leeg nqaij puas). Echo tuaj yeem ua rau hauv cov xwm txheej sib npaug los ntawm tus kws kho plawv tham
Cerebellar infarction txhais li cas?
Lub cerebellar infarct (lossis mob stroke cerebellar) yog hom cerebrovascular tshwm sim uas cuam tshuam nrog posterior cranial fossa, tshwj xeeb yog cerebellum. Kev ua tsis tau zoo txo cov pa oxygen thiab ua rau lub cev tsis muaj zog thiab tswj kev tshuav nyiaj li cas
Transmural siab txhais li cas?
Transmural siab yog qhov sib txawv ntawm qhov siab ntawm ob sab ntawm phab ntsa lossis sib npaug sib cais. Rau lub cev vasculature lossis lwm yam kabmob hauv nruab nrog cev, saib cov leeg du#Kev cog lus thiab kev so kom txaus. Rau lub ntsws, saib Transpulmonary siab
Yuav kho tus mob myocardial infarction li cas?
Thrombolytics feem ntau siv los daws cov ntshav txhaws. Cov tshuaj Antiplatelet, xws li clopidogrel, tuaj yeem siv los tiv thaiv cov ntshav txhaws tshiab los ntawm kev tsim thiab cov pob txha uas twb muaj lawm los ntawm kev loj hlob. Nitroglycerin tuaj yeem siv los nthuav koj cov hlab ntsha. Beta-blockers txo koj cov ntshav siab thiab so koj cov leeg nqaij
Ua li cas myocardial infarction ua rau DKA?
Mob Myocardial Infarction hauv Cov Neeg Mob Mob Ntshav Qab Zib Mob MI yog qhov ua rau DKA hauv kwv yees li 4% ntawm cov neeg mob ntshav qab zib uas muaj mob MI. Thaum lub sijhawm DKA cov xwm txheej, myocardium raug txwv tsis pub noj cov piam thaj vim tias muaj cov ketones siab thiab cov rog dawb, ua rau myocardial ischemia
