Peb siv ib kev ntsuam xyuas kev nyuaj siab adenosine nrog kev ntsuas (myocardial perfusion imaging) rau cov neeg mob uas tsis tuaj yeem tawm dag zog ntawm lub treadmill. Tshuaj kev ntxhov siab yog siv los ntsuas cov ntshav hauv cheeb tsam mus rau lub plawv cov leeg ob ntawm kev nyuaj siab thiab so. Pharmaceutical kev nyuaj siab yog siv los ua kom cov ntshav khiav mus rau lub plawv cov leeg.
Hauv txoj kev no, adenosine ua haujlwm li cas hauv kev ntsuas kev nyuaj siab?
Thaum lub sij hawm xeem , koj yuav tau txais cov tshuaj me me ( adenosine , dipyridamole lossis regadenoson). Cov tshuaj no ua rau cov hlab ntsha hlab ntshav qhib (nthuav dav) zoo ib yam li lawv ua thaum koj tawm dag zog. Qhov no ua rau cov ntshav ntws ntau dua thiab simulates cov txiaj ntsig ntawm kev tawm dag zog rau cov neeg mob uas tsis tuaj yeem tawm dag zog ntawm lub treadmill.
Lawv txhaj tshuaj dab tsi thaum kuaj kev ntxhov siab? Cov tshuaj radioisotope lossis radiopharmaceutical, xws li thallium lossis sestamibi, yog txhaj los ntawm IV. Cov khoom siv hluav taws xob ntsuas koj cov ntshav ntws thiab tau khaws los ntawm lub koob yees duab gamma. Cov xeem suav nrog ib qho kev tawm dag zog thiab so, thiab koj lub siab tau yees duab thaum ob leeg.
Tsis tas li lo lus nug yog, puas yog adenosine kev ntsuas kev nyab xeeb?
Adenosine yog dav siv rau pharmacological kev ntxhov siab nyob rau hauv myocardial perfusion imaging thiab muaj ib tug zoo tsim kev nyab xeeb sau tseg. Nws qhov cuam tshuam tsawg kawg nkaus ntawm lub plawv dhia thiab ntshav siab nrog kev hloov me ntsis ntawm ob (tus nqi-siab) cov khoom ua rau me ntsis ntxiv oxygen yuav tsum tau thiab tsis tshua muaj tseeb ischemia.
Yuav muaj dab tsi tshwm sim thaum koj kuaj tshuaj lom neeg?
Hauv ib kuaj tshuaj lom neeg , tus neeg mob tau txais cov tshuaj uas ua kom lub plawv dhia ceev lossis nthuav cov hlab ntsha. Raws li nyob rau hauv xeem nrog kev tawm dag zog, qhov no kuj tseem hu ua "so scan" ntawm lub plawv. Tus kws kho mob mam li muab tshuaj kho kom nrawm dua lub plawv lossis nthuav cov hlab ntsha.
