Complexity of lower extremity peripheral artery disease reflects the complexity of coronary artery disease

Abstract

We investigated the relationship between peripheral artery disease complexity and coronary artery disease complexity in patients with peripheral artery disease. A total of 449 patients were enrolled. SYNTAX score, a marker of coronary artery disease complexity, was assessed by dedicated computer software and complexity of peripheral artery disease was determined by Trans Atlantic Inter-Society Consensus II classification. The SYNTAX score of patients with minimal peripheral artery disease, Trans Atlantic Inter-Society Consensus A, Trans Atlantic Inter-Society Consensus B, Trans Atlantic Inter-Society Consensus C and Trans Atlantic Inter-Society Consensus D were 5 (11), 12.5 (13.25), 20 (14), 20.5 (19) and 27.5 (19), respectively (values in brackets represent the interquartile range). SYNTAX score and Trans Atlantic Inter-Society Consensus class was moderately correlated (r = 0.495, p < 0.001). In multivariate regression analysis male sex (B = 0.169, p < 0.001, CI95% = 0.270–0.735), Log10 SYNTAX score (B = 0.282, p < 0.001, CI95% = 0.431–0.782), Log10 creatinine (B = 0.081, p = 0.036, CI95% = 0.043–1.239), low-density lipoprotein (B = 0.114, p = 0.003, CI95% = 0.001–0.006) and high-density lipoprotein (B = −0.360, p < 0.001, CI95% = −0.063 to −0.041) were the independent predictors of Trans Atlantic Inter-Society Consensus II class. We have shown that patients with complex peripheral artery disease had complex coronary artery disease.
