Usefulness of Elevated Levels of Growth Differentiation Factor-15 to Classify Patients With Acute Coronary Syndrome Having Percutaneous Coronary Intervention Who Would Benefit from High-Dose Statin Therapy

The aim of this study was to evaluate whether growth differentiation factor-15 (GDF-15) plasma concentration at the time of percutaneous coronary intervention (PCI) might help identify those patients with acute coronary syndrome (ACS), who benefit most from high-dose statin treatment. Two hundred eighty-four consecutive patients, who underwent percutaneous coronary intervention (PCI) for ACS, were included in a prospective registry. The combined end point at 3 months after PCI consisted of cardiovascular death, nonfatal myocardial infarction, and unstable angina. Patients were divided into those with elevated levels of GDF-15 and those with lower levels in relation to the median plasma concentration. Results were compared between patients receiving high-dose, highly efficient statins and patients receiving low-dose statins or no statins. The median GDF-15 plasma concentration was 3.31 ng/ml. One hundred six patients (74.6%) of the high GDF-15 group and 122 patients (85.9%) of the low GDF-15 group received high-dose statins. The combined end point was statistically lower in patients with high levels of GDF-15 treated with high-dose statins compared with patients treated with low-dose statins or without statin treatment (3.8% vs 22.2%, hazard ratio [HR] = 0.156; 95% confidence interval [CI], 0.047 to 0.519; p = 0.002). After propensity score adjustment, the results remained significant (adjusted HR for high-dose statins = 0.148; 95% CI, 0.045 to 0.494; p = 0.002). In contrast, in patients with lower levels of GDF-15, there was no significant reduction in combined end point rates associated with high-dose statin treatment (1.6% vs 5.0%, HR = 0.320; 95% CI 0.029 to 3.534; p = 0.353). In conclusion, increased GDF-15 plasma concentrations at the time of PCI and stent implantation might classify high-risk patients with ACS who benefit from high-dose, highly efficient statins.
