Ingaba intliziyo yakho ifumana igazi elaneleyo? Masithethe ngeCoronary Flow Reserve (CFR)

Ngaba wakha wazibuza ukuba kwenzeka ntoni entliziyweni yethu xa sizilolonga, sibaleka, okanye sinyuka izinyuko? Ngelo xesha, intliziyo ifuna ioksijini engaphezulu kunesiqhelo. Ukuze kuhlangatyezwane nale mfuneko ikhulayo yeoksijini, ubungakanani begazi elihamba ngemithambo yentliziyo ehambisa igazi entliziyweni ngokwayo kufuneka bunyuke. Ngoko ke, amandla entliziyo yakho okwandisa ukuhamba kwegazi xa isidingo sisanda abizwa ngokuba yiCoronary Flow Reserve (CFR). Oku kufana 'namandla okugcina' entliziyo yakho.

Yintoni iCoronary Flow Reserve (CFR)?

Ngamafutshane, iCoronary Flow Reserve (CFR) yindlela yokulinganisa ukuba igazi elingakanani elihamba ngemithambo yentliziyo yakho elinokwandiswa ngexesha lokuzivocavoca kakhulu. Oku kunokunika ugqirha wakho ulwazi oluxabisekileyo malunga nempilo yentliziyo yakho, ingakumbi imeko yemithambo ehambisa igazi entliziyweni yakho (imithambo yentliziyo).

Cinga ngale ndlela. Xa uhleli esitulweni, intliziyo yakho ifuna igazi elithile. Kodwa xa ubaleka ngequbuliso emva kwebhasi, umsebenzi wentliziyo yakho uyanda kakhulu. Intliziyo yakho ifuna ioksijini ephindwe kathathu ukuya kane kunesiqhelo. Imithambo yegazi yentliziyo esempilweni inokujongana nale mfuno ikhulayo, inyuse ukuhamba kwegazi ngoko nangoko. Uvavanyo lwe-CFR lulinganisa amandla entliziyo yakho okwenza oku.

Olu vavanyo lunceda ekuchongeni kwangethuba ukuba unesifo semithambo yegazi okanye usemngciphekweni wokuba nesifo esifana nokuhlaselwa yintliziyo kwixesha elizayo.

Ixabiso le-CFR libalwa njani?

Indlela oku kubalwa ngayo ilula kakhulu. Ugqirha wakho ulinganisa ukuhamba kwegazi entliziyweni yakho ngeendlela ezimbini.

1. Ukuhamba kwegazi ngexesha lokuphumla: Oku kulinganisa ubungakanani begazi elihamba liye entliziyweni xa uphumle, ngaphandle kokwenza nantoni na.

2. Ubuninzi bokuhamba kwegazi: Intliziyo inyanzelwa ukuba ipompe igazi ngomzamo omkhulu (kunikwa iyeza loku), kwaye inani eliphezulu legazi elihamba ngelo xesha liyalinganiswa.

Emva koko, olu hambo lwegazi luphezulu lwahlulwe luhambo lwegazi oluphumlileyo.

I-CFR = (Ukuhamba Kwegazi Okuphezulu) / (Ukuhamba Kwegazi Okuphumzayo)

Umzekelo, ukuba ukuhamba kwegazi lakho eliphezulu kuphindwe kathathu ukuhamba kwegazi lakho lokuphumla, ixabiso lakho le-CFR liya kuba yi-3.

Ithini ixabiso eliphakathi le-CFR?

I-CFR yomntu ophilileyo kufuneka ibe phakathi kwe-2.0 kunye ne-2.5 . Oku kuthetha ukuba intliziyo kufuneka ikwazi ukupompa igazi eliphindwe kabini kunokuba inako xa iphumle. Kumntu ophilileyo, eli xabiso linokuba yi-3, 4, okanye ngaphezulu.

• Ukuba ixabiso le-CFR lingaphantsi kwe-2.0:Oku kuthetha ukuba kunokubakho ingxaki ethile ngemithambo yegazi entliziyweni. Mhlawumbi imithambo yegazi inciphile (ivaliwe). Abantu abanjalo basengozini enkulu yokufumana isifo sentliziyo kwixesha elizayo.
• Ukuba ixabiso le-CFR lingaphezulu kwe-2.0: Libonisa ukuba ukusebenza kwemithambo yegazi entliziyweni kukwinqanaba elifanelekileyo.

Uyenza njani uvavanyo lwe-CFR?

Kukho iindlela ezimbini eziphambili zokwenza olu vavanyo: enye yindlela yokungena emzimbeni, equka ukufaka isixhobo emzimbeni, kwaye enye yindlela yangaphandle, equka ukuyenza ngaphandle kokungena emzimbeni.

Ufanele uzilungiselele njani ngaphambi kovavanyo?

Ugqirha wakho uza kukuchazela oku. Ngokuqhelekileyo, kufuneka uzilumkele ezi zinto.

• Ulwazi Ngamayeza: Xelela ugqirha wakho ngawo onke amayeza owasebenzisayo (owamayeza kagqirha nalawo athengiswa ngaphandle kwemvume kagqirha). Amanye amayeza anokuchaphazela ukujiya kwegazi kwaye unokucelwa ukuba uyeke ukuwasebenzisa ngosuku olungaphambi kovavanyo.
• Ii-Allergies: Qiniseka ukuba uyasixelela ukuba unayo nayiphi na i-allergies kumayeza okanye idayi yokwahlulahlula.
• Ukuzila Ukutya: Ukuba uxilongwa nge-cardiac catheterization okanye nge-PET scan, kuyacetyiswa ukuba uyeke ukutya okanye ukusela iiyure ezi-6-8 ngaphambi kovavanyo.
• Kwi-MRI: Awunakugqoka naziphi na izinto zesinyithi (ubucwebe, iiwotshi) emzimbeni wakho. Ukuba unesixhobo esifana ne-pacemaker emzimbeni wakho, buza ugqirha wakho kwangaphambili ukuba sikhuselekile na kwi-MRI.

Yintoni onokuyilindela ngexesha lovavanyo?

Nokuba yeyiphi na indlela yovavanyo onayo, ityhubhu ye-IV (i-cannula) iya kufakwa engalweni yakho. Amanyathelo ovavanyo aya kujongeka ngolu hlobo.

1. Umlinganiselo wokuphumla: Okokuqala, ukuhamba kwegazi entliziyweni yakho kulinganiswa ngelixa uzolile kwaye uphumle.

2. Ukunika iyeza: Okulandelayo, iyeza (i-vasodilator) elikhulisa imithambo yegazi entliziyweni yakho kwaye lenze ukuhamba kwegazi kube ngcono linikwa nge-IV. Eli yeza elisetyenziswa kakhulu yi -Adenosine . Xa linikwa, ukuhamba kwegazi entliziyweni kuyanda ngokuphindwe ka-4-5 kwimizuzu emi-2-3.

3. Umlinganiselo wencochoyi: Xa ukuhamba kwegazi kufikelela kwinqanaba eliphezulu emva kokuba iyeza linikwe, ukuhamba kwegazi kulinganiswa kwakhona.

4. Ukuthelekisa: Okokugqibela, ezi metrics zimbini zithelekiswa nokubala ixabiso lakho le-CFR.

Ukuba une-cardiac catheterization, unganikwa i-sedative ukuze ikuncede ulale kancinci. Oku kuya kukunceda ungaziva ungonwabanga. Xa usenza i-scan, kubaluleke kakhulu ukuhlala ungashukumi ukuze ufumane imifanekiso ecacileyo.

Kwenzeka ntoni emva kovavanyo?

Emva kovavanyo, ungaphila ubomi obuqhelekileyo, kodwa kufuneka uqaphele ezinye izinto.

• Ukuba ukhe waxilongwa nge-cardiac catheterization, kuya kufuneka ugcine ingalo okanye umlenze apho i-catheter ifakwe khona ume nkqo kangangeyure ukuze uthintele ukopha.
• Ugqirha uza kukucebisa ukuba usele amanzi amaninzi ukuze idayi yomahluko iphume emzimbeni wakho ngokukhawuleza.
• Ukuba unikwe iyeza lokuthomalalisa ingqondo, awunakuqhuba ngaloo mini. Kubalulekile ukuba kubekho umntu okuphelekayo xa usiya ekhaya.

Ngaba kukho naziphi na iingozi okanye iziphumo ebezingalindelekanga kolu vavanyo?

Uvavanyo lwe-CFR luvavanyo olukhuselekileyo kakhulu, kodwa njengalo naluphi na uvavanyo lwezonyango, kukho iingozi ezincinci kakhulu.

• Iingozi ezinxulumene ne-catheter:Ngexesha lokufakwa kwe-catheter kwintliziyo, amahlwili egazi, umonakalo kwimithambo yegazi, okanye ukopha akunakwenzeka rhoqo.
• Iziphumo ebezingalindelekanga ze-adenosine: Abanye abantu banokufumana oku kulandelayo imizuzwana embalwa emva kokuba benikwe eli yeza:
• Isingqisho sentliziyo esingaqhelekanga
• Uxinzelelo lwegazi oluphantsi
• Ubunzima bokuphefumla
• Ukungonwabi esifubeni

Ezi mpawu ziyaphela ngokupheleleyo kwangoko nje ukuba iyeza liphele (kungekapheli nomzuzu) . Akukho nto inokubangela uxhalaba ngayo.

Zithetha ukuthini iziphumo kwaye siza kwazi nini?

I-CFR yakho yinombolo ekuxelela ukuba intliziyo yakho inokupompa igazi elingakanani xa ixinezelekile.

Kungathatha iintsuku ezimbalwa ukuba ugqirha ahlalutye iziphumo zovavanyo aze anike ingxelo. Ngamanye amaxesha, ukuba iziphumo azikho ngqiqweni, ezinye iingcali zinokuboniswana nazo.

Ukuba iziphumo zakho zibonisa umngcipheko wesifo sentliziyo, ugqirha wakho uza kukunika isicwangciso sonyango sokunciphisa loo mngcipheko.
