Abstract
The prognostic significance of d-dimer level in patients with coronary artery disease (CAD) is not fully established. This meta-analysis aimed to examine the association between elevated d-dimer level at baseline and adverse outcomes in patients with CAD. Two independent authors comprehensively searched PubMed and Embase databases from their inception to December 31, 2020. All observational studies reporting the values of baseline d-dimer level in predicting the major adverse cardiovascular events (MACEs) or survival outcomes in patients with CAD were included. The prognostic values were calculated by pooling adjusted RR with 95% CI for the highest versus the lowest d-dimer level. Thirteen studies consisting of 25 600 patients with CAD were identified. Comparison between the highest and lowest d-dimer level showed that the pooled multivariable adjusted RR was 1.69 (95% CI, 1.53-1.86) for all-cause mortality, 2.37 (95% CI, 1.52-3.69) for cardiovascular mortality, and 1.44 (95% CI, 1.19-1.74) for MACEs, respectively. Elevated blood level of d-dimer at baseline was independently associated with higher risk of MACEs, cardiovascular death, and all-cause mortality in patients with CAD. The baseline d-dimer level may have important prognostic value in patients with CAD.
