pulmonary hypertension nyob rau miv (PH) yog suav hais tias yog ib tug complex syndrome yam ntxwv los ntawm ib tug ntshav siab.nyob rau hauv cov qauv uas ua rau lub vascular network ntawm lub ntsws. Hauv tsev kho tsiaj, PH suav nrog ntau yam kev kho mob tshwm sim thiab feem ntau yog cais raws li nws cov etiology (kev txheeb xyuas qhov ua rau) thiab nws cov txheej txheem pathophysiological (tus cwj pwm thiab kev hloov pauv hauv lub cev).
Txawm hais tias qhov pathology no muaj qhov tshwm sim tsawg hauv cov tub ntxhais hluas, nws tuaj yeem tshwm sim nrog qee zaus hauv cov neeg laus felines, txawm tias lawv yog mestizo lossis ntawm ib hom tsiaj. Tau kawg, peb yuav tsum hais txog qhov tseem ceeb ntawm mus rau ib tus kws kho tsiaj uas ntseeg siab thaum soj ntsuam ib qho kev hloov pauv ntawm qhov tsos lossis tus cwj pwm ntawm koj tus miv.
Txawm li cas los xij, hauv tsab xov xwm no ntawm peb qhov chaw, peb piav qhia lub ntsiab cov tsos mob, ua rau thiab muaj feem cuam tshuamntawm Kab Mob Ntshav Qab Zib hauv miv, los pab koj paub txog cov tsos mob ntawm tus kab mob no thaum ntxov hauv koj tus menyuam dev.
pulmonary hypertension yog dab tsi?
Lub ntsws ntawm felines muaj lub peev xwm vascular network, tab sis nrog tsis tshua muaj siab thiab tsis kam, uas koom ncaj qha rau hauv cov txheej txheem ntawm ua pa thiab oxygenation ntawm cov ntaub so ntswg ntawm koj lub cev. Txhawm rau tsim kom muaj kev sib piv, qhov kev tiv thaiv ntawm lub plawv (systemic) vascular network tuaj yeem ncav cuag 10 npaug ntau dua li ntawm lub ntsws hauv cov neeg noj qab haus huv. Raws li qhov tshwm sim, cov kab mob plawv tau npaj los tiv thaiv lub siab ntau dua li lub network ntawm cov hlab ntsha thiab cov hlab ntsha.
Txawm li cas los xij, muaj qee yam kab mob, malformations lossis muaj feem cuam tshuam tuaj yeem ua rau nce siab thiab tiv thaiv pulmonary vascular lug. Qhov no pulmonary hypertension feem ntau cuam tshuam ncaj qha rau lub ntsws cov ntaub so ntswg thiab kev ua haujlwm ntawm cov kab mob plawv, ua rau lub cev tsis muaj oxygenation ntawm lub cev cov ntaub so ntswg.
Precisely vim li no, pulmonary hypertension nyob rau hauv miv yog suav hais tias yog ib tug complex syndrome thiab nws cov teebmeem muaj kev txhawj xeeb, vim lawv tuaj yeem muaj kev cuam tshuam tsis zoo. Nyob rau hauv kev xyaum tag nrho cov kabmob uas yuav tsum tau txais kom raug oxygenation los lav lawv txoj kev ua haujlwm zoo.
Symptoms of pulmonary hypertension in miv
Feline pulmonary hypertension encompasses ntau yam kev kho mob tshwm sim, tab sis feem ntau cov tsos mob ntawm pulmonary hypertension nyob rau hauv miv yog:
- Exertional dyspnea: nws yog feem ntau yog ua tsis taus pa luv thiab nyuaj rau rov qab los ntawm exertion ntawm txhua yam. Txawm li cas los xij, thaum mob hnyav dua, ua tsis taus pa tuaj yeem ua tau mus tas li, txawm tias thaum so.
- Constant Exhaustion: Felines with pulmonary hypertension tej zaum yuav nkees tas li thiab ua rau qaug zog tas li. Vim tsis muaj peev xwm ua pa thiab qaug zog, miv yuav poob siab rau kev ua si thiab ua haujlwm txhua hnub, xws li noj lossis haus dej. Thaum mob hnyav dua, tus tsiaj kuj tso zis thiab tso zis tawm sab nraum lub thawv khib nyiab.
- Zoo siab los yog mob plab.
- Poob qab los noj mov.
- Hlub arrhythmia.

Causes and risk factor of pulmonary hypertension in miv
Hauv tib neeg cov tshuaj, pulmonary hypertension tej zaum yuav yog idiopathic (tseem hu ua "primary") los yog secondary, nyob ntawm nws aetiology. Idiopathic tej yam kev mob yog cov uas tshwm sim "ib leeg", uas yog, lawv tsis muaj feem xyuam rau ib tug hauv paus ntsiab lus. Txawm li cas los xij, idiopathic PH tsis tshua pom nyob hauv tsev kho tsiaj.
Pulmonary hypertension in miv feem ntau yog los ntawm lwm tus kab mob, yog li nws feem ntau suav hais tias yog cov tsos mob ntawm daim duab kho mob ntau dua. Secondary PH feem ntau yog txuam nrog ntau yam ua rau thiab tuaj yeem cuam tshuam rau cov hlab ntsha thiab cov hlab ntsha.
Txawm hais tias tseem tsis tau muaj kev pom zoo hauv Veterinary Medicine ntawm kev faib cov PH, qhov tseem ceeb tshaj plaws yog lees txais thiab lees txais tib qhov kev faib tawm hauv tib neeg. Hauv qab no, peb piav qhia qhov sib txawv tseem ceeb, ua rau thiab cov txheej txheem pathophysiological ntawm idiopathic thiab theem nrab PH hauv miv.
Idiopathic pulmonary hypertension hauv miv
Nyob rau qee kis, cov txheej txheem kuaj mob kom ntxaws tsis muaj peev xwm nthuav tawm qhov tshwj xeebua rau PH. Thaum qhov no tshwm sim, nws muaj feem ntau uas peb tab tom cuam tshuam nrog idiopathic pulmonary arterial hypertension (yav tas los hu ua "primary").
Nyob rau hauv idiopathic PAH, muaj ib tug dysfunction nyob rau hauv lub endothelium(phab ntsa ntawm cov ntshav capillaries) ntawm neuroendocrine keeb kwm uas cuam tshuam rau vascular network ntawm lub ntsws, ua rau muaj kev pheej hmoo rau vasoconstriction thiab thrombosis. Qhov mob no pib hauv cov hlab ntsha me me, uas cuam tshuam los ntawm kev tsim ntawm me me clots (thrombi). Raws li qhov tshwm sim, kev poob ntawm ntau cov hlab ntsws pulmonary thiab nce vascular siab hauv lub ntsws tuaj yeem pom.
Txawm hais tias muaj ntau qhov kev sib tham txog qhov ua tau ntawm idiopathic PAH hauv felines, laus thiab rog tshwm sim los ntawm kev pheej hmoo, vim lawv haum rau hnav ntawm lub plawv thiab pulmonary vascular lug. Tam sim no, kev tshawb fawb tseem tab tom ua los ntawm qhov cuam tshuam ntawm genetic factor in the predisposition to idiopathic PH in miv.
Pulmonary Hypertension in Cats
Raws li qhov ua rau thiab pathophysiological mechanism, theem nrab PH hauv miv feem ntau muab faib ua 4 lub ntsiab "hom". Hauv qab no, peb sau cov yam ntxwv tseem ceeb ntawm txhua hom kab mob ntshav siab hauv cov miv:
- PAH thib ob rau pulmonary hypercirculation: nyob rau hauv cov ntaub ntawv no, kev nce ntshav siab yog pom nyob rau hauv cov hlab ntsha pulmonary, muab los ntawm daim duab ntawm hypercirculation. Qhov ntawd yog hais tias: cov ntshav ntws hauv cov hlab ntsha pulmonary muaj ntau zaus thiab siv zog, uas ua rau muaj kev nce siab hauv cov hlab ntsha no. Feem ntau ua rau yog kab mob hauv lub plawv uas ua rau muaj kev sib txawv ntawm cov ntshav ncig, xws li patent ductus arteriosus (PDA) thiab interatrial septum. Feem ntau, hom PAH no feem ntau kuaj pom hauv cov miv me uas muaj qhov tsis zoo ntawm cov kab mob plawv.
- Pulmonary hypertension vim yog cov kab mob ua pa: Qee cov kab mob ua pa tuaj yeem ua rau hypoxia thiab ua rau muaj kev pheej hmoo ntawm pulmonary vasoconstriction. Raws li qhov tshwm sim, pulmonary vascular qauv yuav raug kev txom nyem thiab tsis ua haujlwm, ua rau muaj kev nce siab hauv pulmonary. Thib ob PH cuam tshuam nrog cov teeb meem ua pa ntev nrog hypoxia tuaj yeem ua rau muaj kev ua haujlwm siab thiab ua haujlwm tsis zoo nyob rau hauv txoj cai ventricle ntawm lub plawv, qhov chaw kho mob hu ua cor pulmonale. Ntawm cov feem ntau ua rau miv, peb pom feline pneumonia, pulmonary fibrosis thiab obstructive tracheobronchial kab mob.
- PH txuam nrog pulmonary thromboembolism: Thromboembolism yog ib daim duab kho mob nyuaj uas tshwm sim los ntawm kev tsim ntawm ntau cov hlab ntsha (thrombi) hauv vascular network. lub ntsws (tsuas yog hauv cov hlab ntsha pulmonary) thiab sab xis ntawm lub plawv. Ib qho ntawm qhov tshwm sim ntawm pulmonary thromboembolism yog qhov cuam tshuam ntawm cov hlab ntsha thiab qhov tshwm sim tsis tu ncua ntawm pulmonary siab. Feem ntau, kab mob plawv tshwm sim yog qhov ua rau ntawm hom PH no. Txawm li cas los xij, muaj lwm yam ua rau, xws li: kab mob uas ua rau hypercoagulability, neoplasms, kab mob glomerular, sepsis, hyperadrenocorticism, thiab lwm yam.
- HP tshwm sim los ntawm kev hloov pauv ntawm sab laug atrium ntawm lub plawv: thaum sab laug atrium nthuav tawm qhov siab siab ntev, cov kua dej ntawm lub plawv. pulmonary veins yog impaired. Raws li qhov tshwm sim, pulmonary venous hypertension tej zaum yuav raug pom, uas feem ntau yog mob me me lossis nruab nrab. Txawm li cas los xij, thaum daim duab no ntxiv rau cov kab mob ua pa lossis thromboembolism, pulmonary hypertension tuaj yeem mob hnyav. Ntawm cov laj thawj tseem ceeb ntawm qhov nce ntshav siab, peb pom dilated cardiomyopathy, congenital mitral dysplasia thiab degenerative valve disease (DVE) uas feem ntau cuam tshuam rau mitral valve.
Diagnosis of Pulmonary Hypertension in Cats
Thaum saib ib qho ntawm cov tsos mob uas tau hais hauv koj tus miv, tsis txhob yig mus sai sai mus rau qhov chaw kho tsiaj. Pulmonary hypertension nyob rau hauv miv yuav tsum tau ua kom ntxaws heev differential diagnosis txhawm rau txheeb xyuas qhov tshwm sim thiab kev kho mob tshwj xeeb tom ntej.
Tom qab kuaj lub cev thiab tshuaj xyuas tus neeg mob keeb kwm, tus kws kho tsiaj yuav thov kom muaj electrocardiogram (ECG), qee qhov thoracic x-rays and clinical analysis (ntshav, zis, quav), los xyuas lub xeev kev noj qab haus huv ntawm tus feline thiab txheeb xyuas qhov evolution ntawm tus kab mob hauv koj lub cev. Kev poob siab ntawm PH feem ntau kuj yuav tsum tau lees paub los ntawm Doppler echocardiography
Ntawm no yog xim Doppler echocardiogram:
Feline Pulmonary Hypertension Treatment
Kev kho mob ntsws pulmonary hypertension nyob rau hauv miv yuav nyob ntawm seb tus mob tshwm sim thiab tus neeg mob tus mob. Feem ntau, tus kws kho tsiaj tau txais kev kho mob yooj yim tswj kev tswj hwm ntawm qee cov tshuaj nrog inhibitory txiav txim ntawm pulmonary vasoconstriction. Tsis tas li ntawd, cov tshuaj uas pab txhawb cov phab ntsa ntawm cov hlab ntsha ntawm cov hlab ntsha hauv cov hlab ntsha tuaj yeem siv tau, txhawm rau txo qis kev ua haujlwm ntawm endothelial dysfunction.
Thaum kuaj pom muaj cov ntshav txhaws (thrombi), cov tshuaj kho mob feem ntau yog ntxiv anticoagulants Ntawm qhov tod tes, qee zaum ntawm congenital plawv malformations nrog deviations, phais kev cuam tshuam yuav raug kawm raws li ib tug siv tau kev kho mob rau cov neeg mob uas muaj kev ruaj ntseg lub xeev ntawm kev noj qab haus huv.
Puas muaj peev xwm tiv thaiv kab mob ntsws ntsws hauv miv?
Kev tiv thaiv ntawm pulmonary hypertension muaj hauv paus hauv kev muab tshuaj tiv thaiv txaus rau tus menyuam hauv nws lub neej. Txhawm rau ua qhov no, nws yog ib qho tseem ceeb uas yuav tsum tau mus ntsib tus kws kho tsiaj tsis tu ncua txhua 6 lub hlis , hwm lub sijhawm txhaj tshuaj tiv thaiv feline thiab lub sijhawm teem sijhawm rau miv deworming. Nws tseem yog ib qho tseem ceeb uas yuav tau muab cov khoom noj muaj txiaj ntsig zoo rau koj cov miv, thiab muab cov khoom ua si, khawb thiab lwm yam khoom siv uas tso cai rau nws siv nws lub cev thiab lub siab txhua hnub.
