Lub keeb kwm ntawm CHD kab mob, cov tsos mob thiab hom ntawm nws cov hoob kawm

Tom qab lub plawv lub hlwb yog lub tseem ceeb tshaj plaws hloov nyob rau hauv tib neeg lub cev. Lub plawv yog lub luag hauj lwm rau tseem ceeb heev functions ntawm tag nrho cov tshuab thiab kabmob, li ntawd, ib yam ntawm lawv tsis txaus ua hauj lwm tsim ntxiv sab nyob rau hauv no tseem ceeb heev hloov khoom nruab nrog. Ischemic kab mob ntawm lub plawv - nws yog ib tug kab mob tshwm sim los ntawm tsis txaus oxygen mov ntawm lub coronary hlab ntsha mus rau lub plawv mob. Keeb kwm ntawm coronary artery kab mob no yog lub narrowing kab mob coronary patency vim atherosclerosis. Nws yuav ua tau mob thiab mob cov hoob kawm, manifested nyob rau hauv xws plawv cov kab mob zoo li mob arrhythmias, heart attack myocardial infarction, angina thiab cia li tuag.

Thaum lub sij hawm lub cev los yog puas siab puas ntsws puas rau siab, raws li zoo raws li nyob rau hauv lub sij hawm ntawm ntshav siab thaum lub plawv tau raug kho kom zoo load yuav tsum tau ntau oxygen noj, myocardial ischemia tshwm sim. Tus neeg mob nyob rau hauv cov lub sij hawm xav tias oppressive, constricting mob nyob rau hauv lub hauv siab, muab ib tug me ntsis mus rau sab laug. Angina feem ntau kis tau tam sim ntawd tom qab qhov kev siv ntawm nitroglycerin. Yog hais tias xws li ib tug keeb kwm ntawm CHD kab mob nrog rau mob exacerbation ntawm angina yog ncua rau ntau tshaj ib teev - muaj yog ib tug loj kev hem thawj rau lub neej.

Nyob ntawm seb cov neeg kawm ntawv ntawm cov pa deficiency ntawm lub plawv, nws ua rau thiab ntev, muaj ntau ntau yam ntaub ntawv ntawm mob ischemia:

- asymptomatic ischemia mus tsis paub rau tus neeg mob thiab ua rau tsis muaj kev tsis txaus siab los ntawm nws.

- Thaum lub sij hawm lub cev ua si los yog yaam puab paub kev nyuaj siab, nrog heev ces ua tsis taus pa thiab mob nyob rau hauv lub hauv siab, muaj ib tug mob kho mob keeb kwm ntawm CHD - angina.

- Rau tsis ruaj tsis khov angina muaj xws li tej angina, surpassing lub hwj chim ntawm yav dhau los tawm tsam, nrog tshiab cov tsos mob. Tej tawm tsam yog pov thawj ntawm cov teeb meem ntawm tus kab mob thiab yog cov thawj harbingers ntawm myocardial infarction.

- Ib tug yam ntxwv feature ntawm arrhythmic ntaub ntawv ntawm cov mob ischemia yog ib tug ua txhaum ntawm nws lub suab, manifested nyob rau hauv atrial fibrillation.

- myocardial infarction - ib tug ib nrab txoj kev tuag ntawm cov kev mob plawv. Nyob rau hauv feem ntau tus neeg mob, tus kab mob no yav dhau los ntawm coronary artery kab mob, ua rau myocardial infarction, a consequence of breakage ntawm cov quav hniav ntawm lub sab hauv phab ntsa ntawm lub coronary artery los yog qhov tshwm sim ntawm ib tug thrombus overlying arterial patency.

- Cov cia li tuag ntawm lub plawv, qhia nyob rau hauv nws ceev halt nws yog ib lub txiaj ntsim ntawm ib tug ntau me me mov ntawm cov ntshav mus rau nws tus nqaij raws li ib tug tshwm sim ntawm tag nrho occlusion ntawm tus poj hlab ntsha.

Tag nrho cov hom ntawm cov khiav ischemia yuav muab tag nrho thiab feem xyuam rau txoj ntxiv rau thaum kawg ntawm tus kab mob no. Piv txwv li, ib tug keeb kwm ntawm tus kab mob coronary mob plawv - angina, feem ntau nrog los ntawm arrhythmia, thiab ces tig mus rau ib tug myocardial infarction, thiab hais txog, mus txog rau lub cia li tuag. Cem deb ntawm lub plawv mob yuav tshwm sim thaum twg los tau theem ntawm tus kab mob, uas yog plaub hom:

- asymptomatic theem no tshwm sim thaum lub sij hawm lub deposition ntawm cholesterol nyob rau hauv cov leeg phab ntsa.

- theem ntawm cov thawj cov cim qhia qhia ntawm kom siab, ib tug siab cov ntsiab lus ntawm qab zib thiab roj uas txhaws taus. Nyob rau hauv no yuav luv ntawm tus kab mob cholesterol plaques yuav npog tau li 50% ntawm ib tug arterial patency.

- Keeb kwm ntawm coronary artery kab mob tus kab mob yus muaj los ntawm ib qho kev nce ntawm cov tsos mob, manifested nyob rau hauv heev ua tsis taus pa, lus lub plawv ua si thiab compressive mob qab lub breastbone. By lub sij hawm no, ultrasound ntawm lub plawv qhia tau hais tias ib qho kev nce rau hauv lub plawv kab noj hniav thiab thinning ntawm lub plawv mob.

- Qhov kawg kauj ruam yog qhia nyob rau hauv ib tug ntev lub plawv tsis ua hauj lwm, ntshav siab, cov tsos ntawm edema, atrial fibrillation, thiab ib tug ntse deterioration nyob rau hauv lub plawv muaj nuj nqi. Mob hauv siab nyob rau ntawm no theem zoo nkaus li nyob rau slightest load.

Heart attack myocardial infarction yog tsis ib txwm tuag, muaj mob thaum cov neeg mob tau pauv mus rau nws ob txhais taw. Tiam sis peb yuav tsum nco ntsoov hais tias ib tug plawv nres yuav inevitably ua rau ib tug acceleration ntawm txoj kev loj hlob ntawm coronary artery kab mob.
