A cikin cututtukan cututtuka na zuciya (CAD), atherosclerosis yana sa sutura, mai rufi na suturar jini don ya zama taurare, mai karfi da kumbura saboda " plaques ," wanda shine adadi na alli, ƙwayoyin cuta da ƙwayoyin ƙwayoyin ƙwayoyin cuta. Daga cikin wadansu abubuwa, wannan yana nufin cewa idan kuna da adadin alkarancin ku a cikin jigilar jini, kuna da akalla CAD.
Shekaru da dama, likitoci sun san cewa wasu fasaha mai kwakwalwa ta kwamfuta (CT) zasu iya ganewa kuma auna ma'aunin maganin kwakwalwa na asibiti . (Sunan da aka ba da nau'o'in ƙwayar CT na zuciya na iya zama rikice, amma duk wani amfani da CT da aka yi amfani dasu don auna nauyin maganin jinin na zuciya shine yawanci ne kawai a matsayin "lakabi na calcium.")

Amfani
An yi jayayya da yawa game da wanda ya kamata ya yi amfani da calcium da kuma yadda za a yi amfani da sakamakon.

Sai dai ya juya, amma, ƙwayar calcium ba ta da kyau sosai saboda wannan dalili. Mutane da yawa marasa lafiya wadanda ke da asibiti mai yawa ba su da manyan matsaloli - duk da ciwon CAD.

A yau, likitoci sun fahimci cewa babban amfani na ƙwayoyin sankara ba shine gano wasu yankunan da suka shafi rikici ba, amma a maimakon gano ko mai haƙuri yana da CAD, kuma idan haka ne, to kimanta tsananinta. Wannan bayani zai iya zama da amfani ƙwarai wajen yanke shawara game da yadda mummunan aiki zai kasance a cikin haɓaka matsalar haɗarin haɗari.
