Ukuba ubuza ukuba leliphi ilungu elibaluleke kakhulu emzimbeni wethu, abantu abaninzi, njengawe, bangathi "intliziyo." Akumangalisi. Kuba intliziyo ngumatshini omangalisayo osebenza ungayeki, ngaphandle komzuzwana omnye wokuphumla, ukususela ngomhla esizalwa ngawo. Ngoko ke ukuze isebenze ungayeki, intliziyo kufuneka ifumane igazi elaneleyo, oko kukuthi, ioksijini kunye nesondlo, akunjalo? Namhlanje siza kuthetha ngento ebaluleke kakhulu enceda ngaloo nto, kodwa asithethi kakhulu ngayo kubomi bethu bemihla ngemihla.
Yintoni iCoronary Perfusion Pressure?
Eli gama lisenokuvakala liyinkimbinkimbi kancinci. Kodwa masiligcine lilula. Cinga ngenkqubo yemibhobho ehambisa amanzi ekhayeni lakho. Ukuze amanzi aphume kwitanki yamanzi aye ekhitshini nakwigumbi lokuhlambela, kufuneka kubekho uxinzelelo oluthile, oko kukuthi, ukutyhala, akunjalo? Ukuba uxinzelelo alwanele, amanzi aya kuhamba kancinci, okanye ayeke kwaphela.
Kunjalo ke ngeentliziyo zethu. Nangona intliziyo ipompa igazi emzimbeni wethu wonke, izihlunu zentliziyo nazo zifuna igazi ukuze zisebenze. Eli gazi linikezelwa entliziyweni ngenkqubo ekhethekileyo yemithambo yegazi ebizwa ngokuba yimithambo yegazi yentliziyo . Ngoko ke, uxinzelelo lweCoronary Perfusion (CPP) luxinzelelo olufunekayo ukuze igazi lityhalwe kwimithambo yegazi yentliziyo liye kwimisipha yentliziyo. Ngamanye amazwi, olu xinzelelo lumisela ukuba intliziyo ifumana ioksijini kunye nezondlo ezifunekayo.
Intliziyo isebenzisa ioksijini engaphezulu kunalo naliphi na elinye ilungu emzimbeni wethu. Oko kuthetha ukuba intliziyo yodwa isebenzisa phakathi kwe -70% kunye ne-80% yeoksijini egazini elihamba ngemithambo yentliziyo. Ngoko khawucinge ukuba ingakanani ioksijini eyifunayo! Yingakho kubaluleke kangaka ukugcina olu xinzelelo lwe-CPP ngokuchanekileyo.
Kutheni le nto olu xinzelelo lubaluleke kangaka?
Ukugcina inqanaba elisempilweni le-CPP kubalulekile ekusebenzeni kwentliziyo. Kukho izizathu ezahlukeneyo zoku.
- Ukunika intliziyo amandla: Intliziyo kufuneka ibethe rhoqo. Oku kufuna amandla amaninzi. Loo mandla avela kwioksijini. I-CPP iqinisekisa ukuba izihlunu zentliziyo zifumana ioksijini eyaneleyo.
- Ukuziqhelanisa neemfuno ezitshintshayo: Khawuthelekelele unyuka izinyuko, usenza umthambo, okanye uzive uxhalabile kancinci. Ngamaxesha anje, intliziyo yakho ibetha ngokukhawuleza, akunjalo? Oko kuthetha ukuba intliziyo yakho ifuna ioksijini engaphezulu kunesiqhelo. Ngamaxesha lawo, ukuze kuhlangatyezwane nemfuno ekhulayo yeoksijini, le CPP kufuneka ibe semgangathweni.
- Iziphumo emzimbeni wonke: Ukuba intliziyo ayisebenzi kakuhle, ichaphazela umzimba wonke. Kuba intliziyo ipompa igazi liye engqondweni, ezintso, esibindini, nakwezinye izinto ezinjalo. Ngoko ke, ukuba intliziyo ayifumani gazi laneleyo, inokuchaphazela ngokungathanga ngqo ukusebenza kwamanye amalungu omzimba.
Ngokwenyani, i-CPP sisalathisi esibalulekileyo sokuba intliziyo iphilile na. Nangona kunjalo, asiyonto esiyilinganisa rhoqo njengokuba silinganisa uxinzelelo lwegazi.
Zeziphi izifo ezinokuvela xa kukho iingxaki ngale CPP?
Ukuba uxinzelelo lweCoronary Perfusion luhla ngendlela enobungozi, oko kuthetha ukuba izihlunu zentliziyo azifumani ioksijini eyaneleyo. Ngokwezonyango, le meko siyibiza ngokuba yiMyocardial Ischemia .
Ngamafutshane, kufana nokuba iiseli zentliziyo zinengxaki "yokuphefumla." Ukuba le meko ihlala ixesha elingaphezu kwemizuzu embalwa, iiseli zemisipha yentliziyo ziqala ukufa ngaphandle kweoksijini. Yiloo nto siyibiza ngokuba kukuhlaselwa yintliziyo .
Makhe sijonge ezinye iimeko zempilo ezinokunxulunyaniswa neengxaki ezibangelwa yile CPP ngezantsi.
| Imeko yezonyango | Kalula nje... |
|---|---|
| Isifo seMitha yeCoronary | Imithambo yegazi (imithambo yegazi) ethwala igazi entliziyweni iyancitshiswa yi-cholesterol, enokuthintela ukuhamba kwegazi kwaye ichaphazele i-CPP. |
| Ukumelwa yintliziyo | Intliziyo ayikwazi ukupompa igazi elaneleyo ukuhlangabezana neemfuno zomzimba. Kule meko, uxinzelelo ngaphakathi entliziyweni lunokwanda kwaye i-CPP inokwehla. |
| Ukothuka kwentliziyo | Ingxakeko esongela ubomi apho intliziyo ingakwazi ukupompa igazi elaneleyo emzimbeni ngenxa yomonakalo entliziyweni (rhoqo emva kokuhlaselwa yintliziyo kakhulu). Kwimeko enjalo, ixabiso le-CPP liyehla liye kwinqanaba eliphantsi kakhulu. |
| I-Coronary Artery Spasm | Ukuqina ngequbuliso (ukuncitshiswa) kwemithambo yegazi entliziyweni, okuyekisa ukuhamba kwegazi okwethutyana. Oku kunokubangela iintlungu esifubeni kunye nokwehla kwe-CPP. |
Iimeko apho iingxaki nge-CPP zinokwenzeka khona
Usenokwenzeka ukuba ube neengxaki nge-CPP ukuba sele unesifo sentliziyo, okanye ukuba intliziyo yakho ifuna ioksijini engaphezulu. Umzekelo:
- Xa usenza umthambo okanye usenza umsebenzi onzima
- Xa uphantsi koxinzelelo olukhulu
- Emva kwesidlo esimnandi (kuba igazi liyafuneka ukuze kugaywe ukutya)
- Xa ujongene nendawo ebandayo
Oogqirha balinganisa njani olu xinzelelo?
Le yeyona nto ibalulekileyo. Ugqirha wakho akayilinganisi le CPP njengoko ubuya kuyilinganisa rhoqo uxinzelelo lwakho lwegazi xa usiya ekliniki. Ifuna iindlela ezikhethekileyo zokuyilinganisa. Kwakhona, ilinganiswa kuphela xa kurhanelwa ingxaki yentliziyo okanye xa kwenziwa into enxulumene nentliziyo, njengotyando lwentliziyo.
I-CPP ibalwa ngokuthatha imilinganiselo emibini kunye nokuthabatha enye kwenye. Oko kuthetha ukuba kukho ifomula elula:
I-CPP = I-ADP - I-LVEDP
Ngoku makhe sibone ukuba ezi leta zithini.
| Umlinganiselo (igama lezonyango) | Kuthetha ukuthini oku? (Kalula nje) |
|---|---|
| Uxinzelelo lwe-Aortic Diastolic (ADP) | Le yinto oyaziyo. Amaxabiso amabini aphantsi afunyanwa xa ulinganisa uxinzelelo lwakho oluqhelekileyo lwegazi. Umzekelo, ukuba uxinzelelo lwakho lwegazi luyi-120/80, i-ADP apha iya kuba yi-80. Oku kubhekisa kuxinzelelo kwi-aorta xa intliziyo iphumle phakathi kokubetha. |
| Uxinzelelo lwe-Diastolic-End Ventricular End-Diastolic (LVEDP) | Oku kunzima kancinci. Kulinganisa uxinzelelo ngaphakathi kwigumbi eliphambili lokumpompa kwentliziyo (iLeft Ventricle) phakathi kokubetha (oko kukuthi, xa izaliswe ligazi, ngaphambi kokuba ipompe). Akukho ndlela iqhelekileyo yokulinganisa oku. Kufuneka uvavanyo olukhethekileyo, olufana nokufakwa kwe-catheter yentliziyo . |
Masiqonde ngomzekelo.
Khawucinge ukuba i-ADP yomntu (uxinzelelo lwegazi oluphantsi lwe-systolic) yi-80 mm Hg. Masithi i-LVEDP yakhe (uxinzelelo ngaphakathi kwentliziyo) ifunyenwe iyi-20 mm Hg ngovavanyo olukhethekileyo.
Emva koko i-CPP yakhe iya kuba:
I-CPP = 80 - 20 = 60 mm Hg
Oogqirha bajonga eli xabiso ukuze babone ukuba intliziyo ifumana igazi elaneleyo na okanye kukho umngcipheko.
Khumbula, le asiyonto siqhele ukuyilinganisa xa sisiya kwitshaneli. Oku kulinganiswa kuphela ngexesha lovavanyo olukhethekileyo olunxulumene nentliziyo okanye utyando. Ngoko ke akufuneki ukhathazeke ngale nto.
Intliziyo yethu kunye nenkqubo yokujikeleza kwegazi yinkqubo entsonkothileyo kakhulu nemangalisayo. Uxinzelelo lweCoronary Perfusion (CPP) yinxalenye ebalulekileyo yaloo nkqubo. Ukuba unesifo sentliziyo, okanye ukuba kukho umntu kusapho lwakho onayo le meko, ugqirha wakho angasebenzisa amagama anje.
Ngamaxesha anjalo, ungoyiki ukubuza uthi, "Andiqondi, gqirha. Ungaphinda uyichaze ngokulula?" Luxanduva logqirha okunika unyango ukuchaza ngokucacileyo umzimba wakho kunye nemeko yakho yempilo. Unelungelo lokubuza imibuzo.
Umyalezo Wokuya Ekhaya
- Uxinzelelo lwe-Coronary Perfusion (CPP) luxinzelelo nje olutyhala igazi elineoksijini kwimisipha yentliziyo yakho.
- Ekubeni intliziyo yethu ifuna ioksijini eninzi ukuze isebenze ngokuqhubekayo, kubaluleke kakhulu ukuba olu xinzelelo lube kwinqanaba elifanelekileyo.
- Ukuba olu xinzelelo luyancipha, intliziyo isenokungafumani ioksijini eyaneleyo (iMyocardial Ischemia) kwaye kusenokubakho iimeko ezinzima ezifana nokuhlaselwa yintliziyo.
- Oku akuyonto ilinganiswa rhoqo njengoxinzelelo lwegazi oluqhelekileyo. Kulinganiswa kuphela ngexesha lovavanyo oluthile lwezonyango okanye utyando olunxulumene nentliziyo.
- Ukuba unyangwa isifo sentliziyo, ungaze ungathandabuzi ukucela ugqirha wakho ukuba akucacisele amagama angawaqondiyo.
