Abstract
Aim: To evaluate the prognostic value of GDF-15 in relation the development of bleeding and events in stable CAD patients, receiving combined antithrombotic therapy.
Materials and methods: The data was obtained from the prospective registry REGATA, 343 CAD patients (249 males), median age 68 [IQR 62; 75] years) were enrolled. Patients with sinus rhythm and concomitant PAD received acetylsalicylic acid in combination with rivaroxaban 2.5 mg bid (31.8%) or clopidogrel (24.8%). Other 43.4% with concomitant atrial fibrillation (AF) received direct oral anticoagulants in combination with antiplatelet therapy after elective percutaneous coronary interventions. Median follow-up was 12 months [IQR 9.0; 18.0]. The safety end point was major and clinically relevant bleedings (type 2-5) according to the BARC classification. Plasma samples for GDF-15 identification were taken at the inclusion and analyzed using ELISA assay.
Results: Frequency of BARC 2-5 bleedings was 16% (BARC 2 - 46; BARC 3 - 9; BARC 4-5 - 0), median GDF-15 level was 1185.0 pg/ml [850.0; 1680.0]. In patients with AF and concomitant MFA, the level of GDF-15 was significantly higher than in the subgroups of patients with only AF or MFA (p=0.0022). According to the quintile analysis, GDF-15 values in the top three quintiles of distribution (cut-off value >943 pg/ml) were associated with higher frequency of bleeding events: 23.2% versus 5.1%; p=0.0001. The multivariable logistic regression model demonstrated that bleeding events were independently associated with GDF-15 level>943 pg/ml (OR 2.65, 95% CI 1.11-6.30; p=0.0275), AF (OR 2.61, 95% CI 1.41-4.83; p=0.0023) and chronic kidney disease (OR 1.92, 95% CI 1.03-3.60; p=0.0401). Clinical factors determining the risk of bleeding events also determined a GDF-15 elevation.
Conclusion: Assessment of GDF-15 level may improve bleeding risk stratification in CAD patients with concomitant AF and/or PAD receiving combined antithrombotic therapy.
