ENew York, NY (ngoNovemba 04, 2021) Ukusetyenziswa kobuchule benoveli obubizwa ngokuba yi-quantitative flow ratio (QFR) ukuchonga ngokuchanekileyo kunye nokulinganisa ubungqongqo be-artery blockages kunokukhokelela kwiziphumo eziphuculweyo kakhulu emva kokungenelela kwe-coronary percutaneous (PCI), ngokutsho Uphononongo olutsha olwenziwe ngentsebenziswano neFakhalthi yeNtaba yeSinayi.
Olu phando, ngowokuqala ukuhlalutya i-QFR kunye neziphumo zayo zeklinikhi ezinxulumene nayo, kunokukhokelela ekwamkelweni okubanzi kwe-QFR njengenye indlela ye-angiography okanye iingcingo zoxinzelelo zokulinganisa ubunzima be-blockages, okanye izilonda, kwizigulane ezine-coronary artery disease.Iziphumo zophononongo zabhengezwa ngoLwesine, ngoNovemba 4, njengovavanyo lwekliniki lwasemva kwexesha kwiNkomfa yeTranscatheter Cardiovascular Therapeutics (TCT 2021), kwaye kwangaxeshanye ipapashwe kwiLancet.
"Ngokokuqala ngqa sinokuqinisekiswa kweklinikhi ukuba ukukhethwa kwesilonda ngale ndlela kuphucula iziphumo kwizigulane ezine-coronary artery disease ezifumana unyango lwe-stent," kusho umbhali ophezulu uGregg W. Stone, MD, uMlawuli weMicimbi yezeMfundo kwiNtaba yeSinayi yeMpilo kunye noNjingalwazi we I-Medicine (i-Cardiology), kunye neMpilo yaBantu kunye nePolisi, kwi-Icahn School of Medicine kwiNtaba yeSinayi."Ngokunqanda ixesha, iingxaki, kunye nezixhobo ezongezelelweyo ezifunekayo ukulinganisa ubunzima bokulimala usebenzisa ucingo loxinzelelo, obu buchule bulula kufuneka busebenze ekwandiseni kakhulu ukusetyenziswa kwe-physiology kwizigulana eziphantsi kweenkqubo ze-catheterization yentliziyo."
Izigulane ezine-coronary artery disease-plaque build-up ngaphakathi kwemithambo ekhokelela kwintlungu yesifuba, ukuphefumula okufutshane, kunye nokuhlaselwa kwentliziyo-ngokuqhelekileyo i-PCI, inkqubo engekho yokuhlinzwa apho i-cardiologists ingenelela isebenzisa i-catheter ukubeka i-stents kwi-coronary evaliweyo. imithambo ukubuyisela ukuhamba kwegazi.
Oogqirha abaninzi baxhomekeke kwi-angiography (i-X-reyi ye-coronary arteries) ukumisela ukuba yeyiphi i-artery ene-blockages enzima kakhulu, kwaye basebenzise olo vavanyo olubonakalayo ukwenza isigqibo sokuba yeyiphi imithambo enokunyanga.Le ndlela ayigqibelelanga: ezinye izithintelo zinokujongeka ngakumbi okanye zincinci kunokuba zinjalo kwaye oogqirha abanakuxela ngokuchanekileyo kwi-angiogram yodwa ukuba yeyiphi imiqobo echaphazela kakhulu ukuhamba kwegazi.Iziphumo zingaphuculwa ukuba izilonda kwi-stent zikhethwa kusetyenziswa ucingo loxinzelelo ukuchonga ukuba zeziphi ezithintela ukuhamba kwegazi.Kodwa le nkqubo yokulinganisa ithatha ixesha, inokubangela iingxaki, kwaye ibandakanya iindleko ezongezelelweyo.
Itekhnoloji ye-QFR isebenzisa ukwakhiwa kwakhona komthambo we-3D kunye nomlinganiselo wesantya sokuhamba kwegazi esinika imilinganiselo echanekileyo yokuhla koxinzelelo kwi-blockage, evumela oogqirha ukuba benze izigqibo ezingcono malunga nokuba yeyiphi i-artery stent ngexesha le-PCI.
Ukufunda indlela i-QFR echaphazela ngayo iziphumo zesigulana, abaphandi baqhube uvavanyo lwamaziko amaninzi, olungahleliwe, olumfamekileyo lwabathathi-nxaxheba be-3,825 e-China abafumana i-PCI phakathi kwe-25 kaDisemba, i-2018, kunye ne-19 kaJanuwari 2020. Izigulane mhlawumbi zahlaselwa yintliziyo kwiiyure ze-72 ngaphambili, ubuncinci ubunomthambo omnye wecoronary ovalekile omnye okanye ngaphezulu owathi i-angiogram yayilinganisa phakathi kwama-50 nama-90 ekhulwini acuthekayo.Isiqingatha sezigulane zenze inkqubo ekhokelwa yi-angiography esekelwe kuvavanyo olubonakalayo, ngelixa esinye isiqingatha safumana isicwangciso esikhokelwa yi-QFR.
Kwiqela elikhokelwa yi-QFR, oogqirha bakhetha ukungaphathi iinqanawa ze-375 ezazijoliswe ekuqaleni kwi-PCI, xa kuthelekiswa ne-100 kwiqela elikhokelwa yi-angiography.Itekhnoloji ke ngoko yanceda ekupheliseni inani elikhulu lama-stents angeyomfuneko.Kwiqela le-QFR, oogqirha baphinde baphatha iinqanawa ze-85 ezingajoliswanga ekuqaleni kwi-PCI xa kuthelekiswa ne-28 kwiqela elikhokelwa yi-angiography.Itekhnoloji ke ngoko ichonge izilonda ezithinteleyo ebezingazukunyangwa ngenye indlela.
Ngenxa yoko, izigulane kwiqela le-QFR zinezinga eliphantsi lonyaka omnye wokuhlaselwa yintliziyo xa kuthelekiswa neqela le-angiography kuphela (izigulane ze-65 vs. Izigulane ze-109) kunye nethuba elincinci lokufuna i-PCI eyongezelelweyo (izigulane ze-38 vs. ukusinda okufanayo.Kumanqaku onyaka omnye, iipesenti ze-5.8 zezigulane eziphathwe ngenkqubo ye-PCI ekhokelwa yi-QFR mhlawumbi yafa, yahlaselwa yintliziyo, okanye ifuna ukuphindaphinda i-revascularization (stenting), xa kuthelekiswa neepesenti ze-8.8 zezigulane ezithatha inkqubo ye-PCI ekhokelwa yi-angiography. , ukuncipha ngama-35 ekhulwini.Abaphandi bathi olu phuculo lubalulekileyo kwiziphumo kwi-QFR evumela oogqirha ukuba bakhethe iinqanawa ezichanekileyo ze-PCI kwaye bagweme iinkqubo ezingeyomfuneko.
"Iziphumo zolu lingo lukhulu olumfamekileyo lungaboni ngasonye lunentsingiselo ekliniki, kwaye ziyafana noko bekulindelekile ngoxinzelelo olusekwe kwi-PCI isikhokelo.Ngokusekelwe kwezi ziphumo, emva kokuvunyelwa okusemthethweni ndiza kulindela ukuba i-QFR yamkelwe ngokubanzi ngabagqirha be-cardiologists abangenelelayo ukuphucula iziphumo kwizigulane zabo. "watsho uGqr Stone.
