Abstract

Abstract: Funding Acknowledgements: Type of funding sources: Public grant(s) – National budget only. Main funding source(s): The grant was given to the Bioimaging field of Semmelweis University by the Excellence Program of the Ministry of Innovation and Technology in Hungary. On Behalf of: Cardiovascular Imaging Research Group (CIRG) Introduction: Diabetes mellitus (DM) is associated with increased cardiovascular morbidity and mortality. However, there is a lack of data about the prevalence of high-risk coronary artery plaques in patients with DM. Purpose: In our study we aimed to compare the prevalence of adverse atherosclerotic coronary artery plaque features between patients with and without DM. Methods: We have analyzed the data of patients who underwent coronary computed tomography angiography (CCTA) between October 2012 and December 2020. Our exclusion criteria were coronary anomaly, congenital or other structural heart disease, previous revascularization or heart transplantation, non-diagnostic image quality and no available data on the presence of DM. Patients were divided into two groups based on the presence of DM. Results: In total, 11357 patients (47.6% men) were included in our study. Prevalence of DM was 14.5%. There were significant differences in age (63.2 ± 9.5 vs 58.1 ± 12.2 years, p < 0.001) and major cardiovascular risk factors such as hypertension, dyslipidemia and smoking between the two groups (all p < 0.05). We have measured higher coronary artery calcium score in patients with DM vs. without DM (424.3 ± 744.0 vs 174.2 ± 794.6, p < 0.001). Luminal stenosis >70% was more frequent in the DM group (24.6% vs 10.5%, p < 0.001). While 29.6% of patients without DM had at least one high risk plaque, this rate was 38.9% in those with DM (positive remodeling: 19.6% vs 26.1%, low attenuation: 7.6% vs 10.2%, spotty calcium: 16.9% vs 21.6%, napkin-ring sign: 1.7% vs 2.6%, all p < 0.05). Conclusions: The prevalence of severe coronary artery stenosis and coronary plaques with adverse characteristics was higher in patients with DM.
