Qhov laj thawj ntawm thrombosis muaj xws li cov ntshav lipids siab, tab sis tsis yog tag nrho cov ntshav txhaws yog tshwm sim los ntawm cov ntshav lipids siab.Ntawd yog, qhov ua rau thrombosis tsis yog tag nrho vim yog qhov sib xyaw ntawm cov tshuaj lipid thiab cov ntshav viscosity siab.Lwm qhov kev pheej hmoo yog kev sib sau ntau dhau ntawm cov platelets, lub cev cov ntshav txhaws.Yog li yog tias peb xav nkag siab tias thrombus tsim li cas, peb yuav tsum nkag siab tias yog vim li cas platelets sib sau ua ke?
Feem ntau hais lus, lub luag haujlwm tseem ceeb ntawm platelets yog coagulate.Thaum peb cov tawv nqaij raug mob, tej zaum yuav muaj los ntshav nyob rau lub sijhawm no.Cov teeb liab los ntshav yuav kis mus rau hauv nruab nrab.Lub sijhawm no, platelets yuav sib sau ua ke ntawm qhov chaw mob thiab txuas ntxiv mus rau hauv lub qhov txhab, yog li thaiv cov hlab ntsha thiab ua tiav lub hom phiaj ntawm hemostasis.Tom qab peb raug mob, cov kab mob ntshav tuaj yeem tshwm sim ntawm qhov txhab, uas yog tsim los tom qab platelet aggregation.
Yog tias qhov xwm txheej saum toj no tshwm sim hauv peb cov hlab ntsha, nws muaj ntau dua uas cov hlab ntsha ntawm cov hlab ntsha puas lawm.Lub sijhawm no, platelets yuav sib sau ua ke hauv qhov chaw puas tsuaj kom ua tiav lub hom phiaj ntawm hemostasis.Lub sijhawm no, cov khoom ntawm platelet aggregation tsis yog cov ntshav txhaws, tab sis cov thrombus peb tab tom tham txog niaj hnub no.Yog li puas yog thrombosis hauv cov hlab ntsha tag nrho los ntawm kev puas tsuaj ntawm cov hlab ntsha?Feem ntau hais lus, thrombus yog qhov tseeb tsim los ntawm kev tawg ntawm cov hlab ntsha, tab sis nws tsis yog qhov tshwm sim ntawm cov hlab ntsha tawg, tab sis kev puas tsuaj ntawm cov phab ntsa sab hauv ntawm cov hlab ntsha.
Hauv atherosclerotic plaques, yog tias qhov tawg tshwm sim, cov roj tso rau lub sijhawm no tuaj yeem raug rau cov ntshav.Ua li no, platelets hauv cov ntshav tau nyiam.Tom qab cov platelets tau txais cov teeb liab, lawv yuav txuas ntxiv mus rau ntawm no thiab nws thiaj li tsim tau ib qho thrombus.
Txhawm rau muab nws yooj yim, cov ntshav lipids tsis yog qhov ua rau thrombosis.Hyperlipidemia tsuas yog tias muaj lipids ntau dua hauv cov hlab ntsha, thiab cov lipids tsis sib xyaw ua pawg hauv cov hlab ntsha.Txawm li cas los xij, yog tias cov ntshav lipid nce ntxiv, nws yuav tshwm sim tias atherosclerosis thiab plaque yuav tshwm sim.Tom qab cov teeb meem no tshwm sim, tej zaum yuav muaj qhov tshwm sim rupture, thiab cov thrombus yog ib qho yooj yim tsim nyob rau lub sij hawm no.
