COMPUTED TOMOGRAPHY IN DETECTING FEATURES OF CORONARY ATHEROSCLEROSIS IN DIFFERENT ETHNIC GROUPS OF KAZAKHSTAN...

Area of Science:

• Cardiology
• Public Health
• Medical Imaging

Background:

• Coronary artery disease (CAD) risk factors and lesion characteristics vary globally.
• Ethnic-specific data on CAD in Kazakhstan is limited.
• Previous studies suggest lower CAD incidence in East Asian populations compared to Europeans.

Purpose of the Study:

• To identify coronary lesion features in Kazakhstan.
• To correlate CAD risk factors (SCORE scale) with coronary artery calcium (CAC) index.
• To analyze these correlations across different age, ethnic groups, and genders in Kazakhstan.

Main Methods:

• Retrospective analysis of 935 patient case histories.
• Multi-slice computed tomography (MSCT) for coronary artery assessment.
• Categorization into Kazakh, Russian, and other ethnic groups.

Main Results:

• Statistically significant ethnic differences observed in BMI, chest pain type, statin use, and blood glucose.
• Coronary atherosclerosis prevalence is higher in Russians than Kazakhs.
• Multivariate analysis revealed significantly higher CAC index in the Russian population (48% higher).

Conclusions:

• Ethnic background influences coronary lesion characteristics and CAD risk in Kazakhstan.
• The Russian population exhibits a higher burden of coronary calcification compared to the Kazakh population.
• Further prospective studies are needed to understand ethnic-specific CAD development and recurrent events.
