Noj qab haus huvCov kab mob thiab mob

Nws kim heev myocardial infarction: qhov xwm ntawm tus pathology, mob, cov tsos mob thiab txim.

Cov kab mob uas muaj feem rau cov hlab plawv system, niaj hnub no yog ua nyob rau hauv lub xov tooj ntawm cov neeg tuag. Tus zaus ntawm cancer pathology yog ho qis uas rationally piav qhov tseem ceeb ntawm qhov teeb meem ntawm raws sij hawm mob thiab kev kho mob. Tab sis ib tug uas nws kim heev lub plawv yuav nres, rau qhov loj cov chaw ntawm cov kev mob plawv, yog nce ntau ntawm cov neeg uas muaj hnub nyoog ntawm 40 xyoo. Yuav kom muaj xws li uas nws kim heev infarction ventricular septal, anterior thiab posterior phab ntsa ntawm lub sab laug ventricle, uas zoo heev cuam tshuam rau hauv lub plawv. Nyob rau hauv cov ntaub ntawv no, nws suffers tsis tau tsuas yog lub plawv mob nws tus kheej, tab sis tag nrho lub cev raws li ib tug tag nrho hemodynamics.

Loj heev lub plawv yuav nres yuav tshwm sim los ntawm cov nram qab no pathologies:

  • atherosclerosis ntawm cov hlab ntsha,

  • ntshav txhaws,

  • sympathetic spasm ntawm cov hlab ntsha ntawm lub pas dej ua ke.

Provoking ib tug loj heev lub plawv yuav nres yam yog xav tau lub cev kev nyuaj siab, kev xav kev zoo siab los yog kev nyuaj siab. Lawv siv los ntawm ib tug series ntawm pathological kev hloov nyob rau hauv lub plawv mob.

Lub mechanism ntawm myocardial infarction

Lub mechanism ntawm koj lub plawv nres tau muab piav qhia raws li nram no: raws li atherosclerosis ntawm cov coronary hlab ntsha ho thiaj li ntshav khiav, ib feem ntawm ntaub so ntswg muaj hypoxia - tsis muaj oxygen. Lub xeev no yog twb dej num raws li ischemic plawv tus kab mob (coronary mob plawv) thiab yog yus muaj los ntawm qhov kuaj pom ntawm atherosclerotic cov quav hniav, narrowing lub lumen thiab arterial sclerosis. Thaum tom siv ntshav txaus yuav tsum tau nce, muab hais tias cov nyiaj mechanisms ntawm lub cev.

Yog li endarterium nyob rau hauv uas muaj yog cov quav hniav cov overstrains qhov twg platelets sai noog. Yog li, ib tug ntshav los khov rau ntawd, uas ntxiv narrows lub lumen ntawm cov hlab ntsha thiab thiaj li ntshav khiav los ntawm lawv. Vim hais tias ntawm no, qhov chaw ntawm infarction raug kev txom nyem los ntawm tsis muaj oxygen, uas tas tus tsom xam ntawm ib lub plawv nres. Nws yuav tsum tau muab sau tseg tias muaj no siv mechanism ntawm ischemic necrosis ntawm tus txheej txheem yuav tsum loj heev, yog li ntawd, tus neeg mob yuav tau txais ib qhov tsim nyog uas nws kim heev myocardial infarction.

tsos mob ntawm koj lub plawv nres

Cov neeg mob yuav luag tam sim ntawd pib muaj kev feem ntau mob mob mob qab lub breastbone, uas yog tsis muab tshem tawm ib zaug xwb koob tshuaj nitroglycerin. Yog hais tias rov nitroglycerin tshwm sim los tsis muaj txo nyob rau hauv cov kev siv ntawm qhov mob, thiab lawv kav ntau tshaj li 20 feeb, nws yuav tsum tau tsis muaj tsis ntseeg nyob rau hauv ib lub plawv nres, uas ib txwm ua rau nws tsim nyog los hu rau ib tug tsheb thauj neeg mob.

Kuaj thiab txim ntawm kev txom nyem ib tug loj heev lub plawv yuav nres

Thaum tus kab mob no yog tus me nyuam mus rau lub mus pw chav tsev yog yuav tsum tau. Muaj yuav tsum nqa tawm diagnostic ntsuas kom meej lub mob thiab tshem tawm ntawm kev mob siab kev mob. ECG Conduct yuav qhia ntxiv txog qhov kev lesion thiab nws cov ntim. Yog li nws kim heev infarction yog yus muaj los ntawm heev heev kev hloov nyob rau hauv ECG. Tsis tas li ntawd ua ntshav biochemical tsom xam, uas yuav qhia cov cim ntawm mob mob. Qhov tseem revealing txoj kev mob ntawm koj lub plawv nres nyob rau hauv thawj lub sij hawm poob yog ib tug txheej txheem ntawm ECG thiab ultrasound, uas qhia gipodinamichnye cheeb tsam uas tsis muab kev koom tes nyob rau hauv contraction. Qhov no yuav tsum yog tus ua kom pom tseeb ntawm ib tug plawv nres, lub volume ntawm uas yuav tsum tau pom los ntawm cov instrumental txoj kev kuaj mob. Nws yuav muaj feem xyuam rau loj cheeb tsam ntawm nqaij thiab tig lawv tawm ntawm kev ua hauj lwm.

Yog li, cov teebmeem ntawm ib tug loj heev lub plawv yuav nres lub plawv yuav yog tus tseem pitiable - plawv cov ntaub so ntswg yuav tsuas qhuav lawm nyob rau hauv qhov chaw no tsim ib tug caws pliav. Nyob rau hauv lub mob nyob ntev uas nws kim heev myocardial ntshav txaus pib mus rau manifest tiv nujnqis tshuav vajvoog, thiab nyob rau hauv lub teeb ntawm cov tsis muaj zog ntawm sab laug ventricle thiab txo tsis ntawm ib tug loj feem ntawm cov nqaij pib stagnate ntshav. Qhov no tej zaum yuav ua rau koj muaj teebmeem kev edema thiab cia li tuag. Tab sis nyob rau hauv cov ntaub ntawv no, mus ncua kev kho mob nyob rau hauv tsev kho mob, vim hais tias nrog raws sij hawm (tsis pub tshaj 4 teev tom qab qhov pib ntawm cov tsos mob ntawm kev mob) siv thrombolytic yuav restore ntshav txaus thiab txo cov ntaub so ntswg kev puas tsuaj. Tsuas yog nrog raws sij hawm kev txais neeg kawm muaj ib tug yawm sij hawm kom txo tau qhov ntim ntawm txhab, heev ntawm cov tsos mob, thiab txuag tus neeg mob lub neej.
