Abstract

Background: Coronary heart disease (CHD) is a major cause of mortality and morbidity all over the world. According to a report of World Health Organization (WHO) in 2005, cardiovascular disease (CVD) caused 17.5 million (30%) of the 58 million deaths that occurred worldwide.

Objective: To evaluate the role of MSCT in cardiovascular risk assessment in asymptomatic people.

Methods: Total 109 patients; 81 patients who are referred from the departments of cardiology with suspicion of coronary artery disease based on CAD consortium score, patients with stent for stent evaluation and 28 asymptomatic patients underwent Plain CT chest for other purpose (with incidentally detected calcium) are included in our study. Duration of study was 15 months from June 2020 to September 2021.

Result: Evaluation of distribution of calcium scores among high and low probability groups revealed higher calcium score has got association with CAD risk.

Evaluation of association between higher calcium score and significant (>50% stenosis) stenotic lesions revealed high calcium score (>400) got clinically significant association with clinically significant (50%) stenosis with no statistical significance. Evaluation of diagnostic performance of CTCAG in detection and grading of stenosis in comparison with gold standard (ICA) revealed accuracy of CT CAG is more in estimating moderate and highgrade stenotic lesions compared to lesions with mild stenosis.

Conclusion: Evaluation of association between higher calcium score and significant (>50% stenosis) stenotic lesions revealed high calcium score (>400) got clinically significant association with clinically significant (50%) stenosis with no statistical significance. Evaluation of diagnostic performance of CTCAG in detection and grading of stenosis in comparison with gold standard (ICA) revealed accuracy of CT CAG is more in estimating moderate and highgrade stenotic lesions compared to lesions with mild stenosis.
