Aim: To assess the value of coronary CT angiography (CCTA) in asymptomatic patients with increased cardiovascular risk.


Material and method. 205 patients with increased cardiovascular risk (mean age 66.2 year) underwent CCTA using dual-source CT. Coronary findings were stratified as unimportant (up to 40% of narrowing), borderline (40-55%) and severe (55% and more). Using the odds ratio, the statistically important differences were tested between subgroup of diabetics and non-diabetics. All patients were under follow-up for two years.

Results: There were 26 patients (12.7%) having the severe stenosis of coronary artery, the coronary angioplasty was performed in five of them, coronary bypass graft surgery in two respectively. Two cases of newly developed unstable angina were noted in group of patients with initially severe stenosis. No myocardial infarction or sudden death was developed within the all group. The severe narrowing had statistically higher incidence in diabetics on the importance level of 5%.

Conclusion: In patients having the increased cardiovascular risk, the morbidity and mortality should be minimized when CCTA is used to test coronary arterial tree.
