Ingabe udokotela wakho uncoma ukuthi uthole ikhalenda yomsindo we-calcium ? Ungase uzibuze ukuthi kudingekile uma unezinye izici ezingozini zomzimba kodwa uvivinyo lokucindezeleka olungabonisi inkinga yenhliziyo.
Umthetho jikelele woluphi uhlolo lwezokwelapha ukuthi kunengqondo ukukwenza noma nini lapho imiphumela yaleso sivivinyo iyoba usizo ekwenzeni isinqumo mayelana nokunakekelwa kwezokwelapha.
Esikhathini sakho, udokotela wakho angasebenzisa imiphumela yesikrini se-calcium ukuze anqume ukuthi noma cha ukubeka ukwelashwa kwesimiso noma cha. Funda kabanzi mayelana neskena ye-calcium nokuthi isetshenziswa kanjani.
Yini I-Calcium Scan Yokutshela Ngenhliziyo Yakho?
Ukuskena kwe-cardiac calcium kuyi-scan ekhethekile ye-CT ethola i-calcium deposits emithanjeni ye-coronary (i-arteries ehambisa igazi ensikeni yesifo senhliziyo). I-calcium deposits yenzeka emithanjeni ngesikhathi kutholakala amapulati e- atherosclerotic . Ngakho-ke, ukuba khona kwe-calcium deposits kusho ukuthi inqubo yesifo se- atherosclerosis ikhona.
Isizathu sokuthi ama-atherosclerotic plaques abalulekile ukuthi lezi zigcawu zivame ukwehla. Ukuqhekeka kwe-plaque kuvame ukuhambisana nokwakhiwa okungazelelwe kwezindwangu zegazi emthini esiteshini sokuphuka, okuholela ekusenikeni okungazelelwe (ukuvinjelwa) komthambo. Lo mcimbi ubizwa ngokuthi i- acute coronary syndrome (ACS) . I-ACS ibangele ukuthi okungenani i- angina engaqiniseki , noma ngaphezulu, i- infarction ye-myocardial (ukushaya kwenhliziyo).
Uma une-calcium emithanjeni yakho ye-coronary, usuvele une-atherosclerosis, futhi usengozini ye-ACS.
Score Calcium
I-calcium scan hhayi nje ikutshele ukuthi (yebo noma cha) unayo i-calcium deposits, kodwa futhi ilinganisa ubukhulu be-deposit calcium futhi yembula ukuthi yiziphi izinkinga zomzimba ezihilelekile.
Lolu lwazi lufingqiwe emkhakheni we- calcium:
- 0: ayikho isifo esikhona
- 1 kuya ku-99: izifo ezincane
- 100 kuya ku-399: izifo ezilinganayo
- 400 noma ngaphezulu: isifo esibi
Ukuphakama kwekhasi le-calcium, i-atherosclerosis kakhulu ikhona emithanjeni ye-coronary, futhi iphakamisa ingozi yokubhekana ne-ACS eminyakeni eminingana elandelayo. Kodwa, okubalulekile, noma yikuphi amaphuzu aphakeme kune-zero kusho ukuthi inqubo yesifo se-atherosclerosis isivele ikhona, kanti okungenani ubukhulu, iyasebenza.
Yini Okushiwo Ngempela I-Calcium Score?
Lapho ukuhlolwa kwe-cardiac calcium kwaqala ukuthengiswa futhi kuthengiswa ekuqaleni kwawo-2000, bezungezwe ngxabano. Ukuphikisana kwakuhlobene ngokukhethekile emathengisini amnandi okwakhiqizwa ukukhangisa kodwa ikakhulukazi ahlotshaniswa neqiniso lokuthi, ngaleso sikhathi, ukusebenziseka kwalezi zingqinamba kwakungaqondakali kahle.
Kule nkathi edlule, izazi zezinhliziyo eziningi zazinesithakazelo ezingxenyeni ze-atherosclerotic ezazikhulu ngokwanele ukudala ukuvimbela okukhulu emithanjeni ye-coronary. Futhi izikali ze-calcium azizona ezinhle kakhulu ekuboneni ukuthi yiziphi izigaxa ezibangela ukwesaba "amaphesenti angu-50" okuthi (kucatshangwa) kufanele aphathwe nge- stents . Ukuhlolwa kokucindezeleka kwakubhekwa emuva ngaleso sikhathi njengethuluzi elibuke kakhulu lokuhlola lezi "blockages" ezibalulekile.
Kusukela ngaleso sikhathi, abacwaningi bezokwelapha baye bafunda okuningi ngokuqhekeka kwamapayipi . Kuvela ukuthi amacala amaningi we-ACS akhona ngokuhlukana kwama-plaque-plaques-plaques angabangela ukuvinjelwa okuphawulekayo, futhi kwakungenakubekwa ukhetho lokugubha. Lokhu kusho izinto ezimbili. Okwokuqala, ngenkathi kugxeka ukuvimbela okuphawulekayo kunganciphisa noma yikuphi ukukhiqizwa kwe-angina okwakhiqizwa yizo zokuvimbela, ngokuvamile akunciphisi amathuba okuhlaselwa kwenhliziyo. Okwesibili, kuvela ukuthi ingozi yenhliziyo yesikhathi eside ihlobene kakhulu "nomthwalo wesikhala" (okungukuthi, inani nenani lamacwecwe kwanoma yisiphi isayizi emithanjeni ye-coronary), kunokuba kube khona noma ukungabikho izinhlamvu ezithile "ezibalulekile".
Ngokusobala, elinye igama lomthwalo we-plaque yiphuzu le-calcium. Ngempela, izifundo sezibonise ngokucacile ukuthi amaphuzu aphezulu e-calcium, aphezulu engozini yomzimba we-cardiac, noma ngabe yiyiphi yalezi zinhlamvu ezibangela ukuvimbela okukhulu.
Yini Okufanele Yenziwe Nge-Calcium Scan Enhle?
Ukufingqa, ukuskena kwe-calcium kukutshela ukuthi ungenawo yini ukutholakala kwe-atherosclerosis emithanjeni ye-coronary, futhi uma kunjalo, ubukhulu be-atherosclerosis. Uma izinga le-calcium liphakeme kune-zero (okungukuthi, futhi, kusho ukuthi okungenani i-atherosclerosis ikhona), ezinye izazi ze-cardiologists zizobe zincoma ukuhlolwa kokucindezeleka, okuzobasiza ukuba banqume ukuthi ngabe yiziphi izigcawu ezibangela ukuvimbela okukhulu. Kodwa lokhu, njengoba sibonile, akusona iphuzu elikhulu.
Iphuzu eliyinhloko ukuthi ngabe unama-atherosclerotic plaques noma cha. Futhi uma wenza-uma ikhalenda yakho ye-calcium iphakeme kune-zero-kubaluleke kakhulu ukwenza konke ongakwenza ukuze unciphise ingozi, hhayi nje kuphela ekuthuthukiseni amapulethi amaningi kodwa futhi nokuqhekeka kwe-plaque.
Ngokusobala, ukukhetha kokuphila okusiza ekuvimbeleni ukuqhubekela phambili kwe-atherosclerosis kuyobe sekugxeka kakhulu. Ukulawulwa kwesisindo, ukuthola umzimba wokuzivocavoca, ukubhema, nokulawula ukucindezeleka kwegazi kanye namazinga we-cholesterol, konke kufanele kubhekwe njengezindaba zokuphila nokufa kunalokho okungenzeka ukuthi wawungakaze wazi ukuthi kakade unama-atherosclerotic plaques.
Izitatimende nazo ziba usizo uma ikhalishi yakho ye-calcium ihle-ngisho noma amazinga akho e-cholesterol aphezulu. Lokhu kungenxa yokuthi ama-statins asiza ekuqiniseni amapulethi futhi kusize ukuvimbela ukuthi bangabonakali. Lokhu, hhayi ikhono labo lokunciphisa i-cholesterol, manje kubonakala sengathi yiyona ndlela eyinhloko ama-statins anciphisa ngayo ingozi yenhliziyo. Ukuthatha i-aspirin ye-dose ephansi nsuku zonke kungabuye kuhlolwe uma ikhalishi yakho ye-calcium inhle.
Izwi elivela
Uma udokotela wakho encoma i-cardiac calcium scan, kufanele ucabange ngokucophelela ukuthi kwenziwa. Ingahlinzeka ngolwazi oluzosiza ukuqondisa ukwelashwa kwakho ukunciphisa ingozi yesifo esibi kakhulu senhliziyo.
