Abstract
Background: D‐dimer is a marker of fibrin degradation that reflects intra‐vascular coagulation. Therefore, plasma concentrations of D‐dimer might predict thromboembolic risk and rivaroxaban treatment effect. Aims: To investigate the association between D‐dimer levels and the risk of stroke and other thrombotic, bleeding and fatal events, and whether D‐dimer concentrations could predict rivaroxaban 2.5mg/bd (vs. placebo) effect in patients enrolled in the COMMANDER‐HF trial who were in sinus rhythm, had HFrEF and coronary artery disease. Methods: Survival models with treatment‐by‐plasma D‐dimer interaction. Baseline measurement of D‐dimer was available in 4,107 (82%) of 5,022 patients enrolled. Median (percentile25‐75) follow‐up was 21 (12.9‐32.8) months. Results: The median (percentile25‐75) plasma concentration of D‐dimer was 360 (215‐665)ng/mL. The D‐dimer tertiles were: 1) ≤255; 2) 256‐515; 3) >515ng/mL. Patients within the tertile‐3 were older, and had lower BMI, blood pressure, hemoglobin, eGFR, and LVEF. Higher plasma D‐dimer concentrations were independently associated with higher rates of death, stroke, and venous thromboembolism. For example, the all‐cause death adjusted HR (95%CI) of tertile‐3 vs. tertile‐1 was 1.77 (1.48‐2.11), p<0.001. The effect of rivaroxaban was similar in each tertile of D‐dimer for all outcomes except stroke. Patients within the tertile‐3 had the greatest absolute and relative stroke reduction (HR [95%CI] tertile‐1=1.16 [0.49‐2.74], tertile‐2=1.45 [0.77‐2.73], and tertile‐3=0.36 [0.18‐0.70]; interactionp=0.008). The number‐needed‐to‐treat to prevent one stroke in tertile‐3 was 36. Conclusion: In COMMANDER‐HF, rivaroxaban reduced the risk of stroke but the benefit may be confined to patients with D‐dimer concentrations above 515ng/mL. Prospective trials are warranted to confirm these findings.
