Aim: Coronary artery calcium (CAC) score has a role in stratifying cardiovascular risk in patients with diabetes. Cardio-ankle vascular index (CAVI) is also a useful method to detect coronary artery calcification. This study compares CAC score with CAVI in the prediction of cardiovascular events in patients with diabetes.
Methods: From August 2006 to June 2008, a total of 626 patients with diabetes who received CAC score assessment with concomitant tests of ankle-brachial index and CAVI were included in this study.
Results: During 4 years of follow-up, 98 participants developed cardiovascular events. There is an increased incidence of coronary revascularization and total cardiovascular events with higher categories of CAC score (P<0.05 when CAC score ≥100). The logistic regression analyses revealed pooled odd ratios for coronary revascularization, and total cardiovascular events were 1.25 [95% confidence interval (CI) 1.03– 1.51, P =0.021] and 1.23 (95% CI 1.07–1.42, P = 0.005), respectively, for high versus low CAVI (CAVI ≥9.0 vs CAVI <9.0). The logistic regression model revealed that a CACscore of ≥1000 rather than a CAVI of ≥9.0 had a higher predictive value for total cardiovascular events.
Conclusions: A CAC score of ≥100 or a CAVI of ≥9.0 predicts future total cardiovascular events in asymptomatic patients with type 2 diabetes. Considering the advantages of CAVI, it can be used as one of the screening tools to reflect coronary atherosclerosis in these patients.
