Abstract:
Background:The American Heart Association estimates that more than 1 million people die each
year from acute coronary heart disease and half a million from acute coronary syndrome, and
that $ 115 billion a year is spent on diagnosing and treating coronary heart disease [Word Health
Organization, 2013].
Goal:In this study we aimed to using coronary computed tomography angiography (CCTA) to
diagnose unstable plaques in coronary artery disease.
Material and methods:From 2018 to 2021, we performed a coronary computed tomography
angiography (CCTA) scan with a Philips Ingenuity 64-slice computed tomography (64 MD-CT)
device and examined 47 patients diagnosed with unstable coronary artery disease at the Reference
centre on Diagnostic Imaging named after R.Purev State Laureate, People’s physician and Honorary
professor of the State Third Central Hospital.
Common statistical measurements such as means and standard errors were calculated. Probability
of results were checked using Student’s test.
Result:In studying signs of coronary computed tomography angiography (CCTA) to diagnose unstable
plaques in coronary artery disease that coronary artery diameters more widening to compared healthy
artery 16(34.0%±6.9), low density sites clarify in plaque (lower than +30HU)- 14(29.8%±6.7), small
calcification detect in plaque 36 (74.5%±6.4), ring liked additional density (lower than +130 HU)
sees in edge of plaque (Halo sign)-9(19.2%±5.8), plaque edge roughness, erosion liked changes- 18
(38.3%±7.1), rupture of intima (dissection)- 8(17.0%±5.5).
Conclusion:We detect that computed tomography angiography (CCTA)’s specific signs of unstable
plaque of coronary artery disease are coronary artery diameters widening, low density sites clarify in
plaque (lower than +30HU), small calcification detect in plaque, ring liked additional density (lower
than +130 HU) sees in edge of plaque (Halo sign), plaque edge roughness, erosion liked changes
and rupture of intima.
