Koj puas paub txog cov hlab ntsha tseem ceeb no hauv koj lub plawv? (Left Anterior Descending Artery) Cia peb tham!

Koj puas tau hnov ​​txog "(Left Anterior Descending Artery)" lossis "(LAD artery)"? Tej zaum koj tus kws kho mob tau tham txog nws, lossis koj tau nyeem txog nws qhov twg. Qhov no yog ib txoj hlab ntshav tseem ceeb heev rau peb lub plawv. Qhov tseeb, nws zoo li cov ntshav ntawm peb lub plawv. Yog li, hnub no peb yuav tham txog "(LAD artery)" no, nws ua dab tsi, cov teeb meem uas nws tuaj yeem ua rau, thiab peb yuav ua li cas saib xyuas nws hauv txoj kev yooj yim uas koj tuaj yeem nkag siab.

Qhov '(Left Anterior Descending Artery)' no yog dab tsi? Nws zoo li daim ntawv qhia ntawm lub plawv!

Hais yooj yim xwb, koj lub `(Left Anterior Descending Artery)`, lossis peb hu nws luv luv tias `(LAD)`, yog ib qho ntawm ob ceg ntawm `(left main coronary artery)` nyob rau sab laug ntawm koj lub plawv. Lo lus ``Anterior'' txhais tau tias ``nyob rau pem hauv ntej.'' Qhov no txhais tau tias cov hlab ntsha no feem ntau xa cov ntshav mus rau pem hauv ntej ntawm koj lub plawv. Xav txog nws, lub chamber twj tso kua mis tseem ceeb nyob rau sab laug qis ntawm koj lub plawv, `(ventricle),'' yog qhov tau txais cov ntshav oxygenated ntau tshaj plaws los ntawm `(LAD) no. Tsis yog li ntawd xwb, tab sis muaj ib daim nqaij ntshiv uas cais cov phab ntsa ntawm lub plawv, peb hu nws tias `( Septum ),'' thiab qhov `(LAD)` no kuj xa cov ntshav mus rau nws.

Qee zaum cov kws kho mob kuj hu cov hlab ntsha no ua "anterior interventricular branch." Txawm hais tias lub npe yuav zoo li nyuaj me ntsis, nws txoj haujlwm yooj yim heev - nqa cov ntshav mus rau lub plawv!

Tiam sis ntawm no yog ib yam uas yuav tsum paub txog: Yog tias cov hlab ntsha '(LAD)' no raug thaiv tag, nws tuaj yeem ua rau mob plawv nres. Qhov no feem ntau hu ua '(widowmaker heart attack )'. Hnov lub npe no tuaj yeem ua rau ntshai me ntsis, vim tias hom mob plawv nres no feem ntau tuaj yeem ua rau tuag taus. Yog vim li ntawd peb thiaj li yuav tsum ceev faj txog qhov '(LAD)' no.

Muaj dab tsi tshwm sim tiag tiag nrog `(LAD)`? Tus neeg muab khoom tseem ceeb ntawm lub siab!

Raws li peb tau hais ua ntej lawm, LAD yog cov hlab ntsha loj tshaj plaws hauv koj lub plawv. Cov no yog ib hom hlab ntsha tshwj xeeb hauv lub plawv, ib feem ntawm lub cev uas nqa ntshav thoob plaws peb lub cev. Koj puas xav txog, yuav luag ib nrab ntawm cov ntshav uas koj lub plawv xav tau yog nqa los ntawm LAD no! Qhov ntawd txhais tau tias nws yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm lub plawv.

Qhov no '(LAD)' nyob qhov twg?

Peb hais tias cov hlab ntsha loj ntawm sab laug ntawm koj lub plawv faib ua ob ceg. Ob ceg ntawd yog Left Anterior Descending Artery thiab Circumflex Artery. Ib yam li txoj kev faib ua ob, cov hlab ntsha loj no kuj faib ua ob ntu ntawm no. Cov kws kho mob kuj hu qhov no ua bifurcation. Cov hlab ntsha LAD no nyob hauv daim nyias nyias tiv thaiv sab nraud ntawm koj lub plawv, epicardium. Nws khiav raws lub septum ntawm lub plawv, zoo li ib lub kwj dej me me, los ntawm lub hauv paus ntawm lub plawv mus rau lub apex ntawm lub plawv.

Cov ceg ntoo hauv `(LAD)` yog dab tsi?

Cov kav dej '(LAD)' no faib ua ob ceg me me:

• Cov ceg diagonal: Cov ceg no muab ntshav rau pem hauv ntej thiab hauv qab ntawm lub ventricle, uas nyob rau sab laug qis ntawm lub plawv.
• (Cov ceg ntawm lub plawv): Cov ceg no muab ntshav mus rau ob feem peb ntawm lub plawv pem hauv ntej.

Cov ceg no muaj lub luag haujlwm los xyuas kom meej tias ntau qhov ntawm lub plawv tau txais cov ntshav txaus.

"Kev ncig ntawm sab laug tseem ceeb" yog dab tsi?

Qhov no yog ib qho kev kawm tob me ntsis, tab sis cia peb sim nkag siab yooj yim. Muaj lwm txoj hlab ntsha hu ua "posterior descending artery (PDA)" uas nqa cov ntshav mus rau qhov qis thiab nraub qaum ntawm koj lub plawv thiab mus rau ib feem ntawm "septum".

• Cov ntshav ncig sab xis tseem ceeb: Yog tias koj coj kaum tus neeg, kwv yees li yim tus ntawm lawv muaj ntshav los ntawm cov hlab ntsha tseem ceeb ntawm sab xis.
• Cov ntshav ncig sab laug tseem ceeb: Txawm li cas los xij, kwv yees li ib ntawm kaum tus neeg, cov PDA no tau txais ntshav los ntawm ib ceg ntawm cov hlab ntsha sab laug tseem ceeb (yog LAD lossis cov hlab ntsha circumflex).
• Kev ncig ntshav sib npaug: Kwv yees li ob ntawm kaum tus neeg, PDA raug xa los ntawm LAD lossis circumflex artery, nrog rau sab xis ntawm lub plawv.

Qhov no yuav txawv ntawm ib tug neeg mus rau ib tug neeg. Nws tsuas yog ib qho chaw ntawm lub siab xwb.

Cov mob dab tsi uas cuam tshuam rau '(LAD)'?

Qhov no yog qhov uas peb yuav tsum tsom ntsoov tshaj plaws. Hauv LAD no, cov rog uas peb hu ua plaque, tuaj yeem sib sau ua ke. Qhov mob no hu ua atherosclerosis . Nws zoo li xeb sib sau ua ke hauv cov kav dej. Rau qee tus neeg, cov plaque no sib sau ua ke ntau heev uas LAD raug thaiv tag. Tom qab ntawd yuav ua li cas? Cov ntshav uas muaj oxygen ntau tsis tuaj yeem mus txog lub plawv. Thaum ntawd peb tau txais tus kab mob plawv widowmaker uas peb tau tham txog ua ntej, uas feem ntau ua rau tuag taus. Txawm hais tias lo lus widowmaker zoo li tsuas yog siv rau cov txiv neej xwb, tus kab mob plawv no tuaj yeem cuam tshuam rau cov txiv neej thiab cov poj niam.

Xav txog seb, Nishantha muaj li ntawm 50 xyoo. Nws rog dhau me ntsis thiab muaj ntshav qab zib. Muaj ib hnub, nws mam li pib tawm hws thiab mob hauv siab heev. Thaum lawv maj nroos coj nws mus rau tsev kho mob, lawv pom tias nws muaj '(mob plawv dhia ceev ceev)'. Zoo hmoo, nws tseem muaj sia nyob vim nws tau txais kev kho mob sai. Qhov no qhia tau tias qhov no yog qhov ceev heev.

Tsis tas li ntawd xwb, muaj ib co neeg tsawg heev uas cov hlab ntsha LAD yuav nqaim me ntsis los yog luv dua thaum yug los. Qhov mob no hu ua hypoplastic left anterior descending artery. Qhov no kuj ua rau muaj qee yam kev pheej hmoo ntxiv:

• Lub plawv dhia tsis xwm yeem `(Arrhythmia )
• Mob plawv nres
• Myocardial ischemia
• Kev tuag sai sai ntawm lub plawv

Cov tsos mob ntawm kev txhaws hauv LAD yog dab tsi?

Yog tias LAD nqaim lossis raug thaiv, koj yuav mob hauv siab (angina) . Qhov no tuaj yeem yog angina ruaj khov lossis angina tsis ruaj khov. Kev mob plawv nres yog xwm txheej ceev uas xav tau kev kho mob tam sim ntawd . Yog tias koj muaj ib qho ntawm cov tsos mob no, hu rau 911 (tus lej xwm txheej ceev 1990 hauv Sri Lanka) tam sim ntawd:

• Mob hauv siab los yog nruj (Angina)
• Hnov txias thiab tawm hws
• Kiv taub hau, zoo li tig hauv lub taub hau
• Qaug zog thiab tsis muaj zog
• Lub plawv dhia ceev
• Xeev siab
• Ua pa nyuaj
• Mob hauv xub pwg lossis caj npab (tshwj xeeb tshaj yog sab caj npab sab laug)

Yog koj muaj ib lossis ntau yam ntawm cov tsos mob no, tsis txhob tsis quav ntsej lawv.

Cov kws kho mob kuaj xyuas koj tus mob '(LAD)' li cas?

Cov kws kho mob siv cov kev kuaj mob zoo li no los xyuas seb koj cov hlab ntsha hauv lub plawv zoo li cas, tshwj xeeb tshaj yog LAD:

• Kev siv catheter rau lub plawv: Qhov no kuaj xyuas seb puas muaj kab mob ntawm cov hlab ntsha hauv lub plawv.
• Kev kuaj mob plawv los ntawm kev siv computer los ntsuas lub plawv (CCTA): Qhov no tuaj yeem tsim cov duab peb-seem (3D) ntawm cov ntshav ntws hauv lub plawv.
• Kev thaij duab intravascular optical coherence tomography (IVOCT) lossis intravascular ultrasound (IVUS): Cov txheej txheem no tuaj yeem thaij duab meej heev, muaj kev daws teeb meem siab los ntawm sab hauv ntawm cov hlab ntsha.
• Fractional flow reserve (FFR): Qhov no ntsuas qhov siab ntawm cov ntshav hauv cov hlab ntsha, uas tuaj yeem pab txiav txim siab seb qhov kev thaiv loj npaum li cas.

Cov kev kuaj no tuaj yeem txiav txim siab tau tseeb seb puas muaj kev thaiv lossis nqaim hauv koj lub LAD.
