BACKGROUND:Growth differentiation factor-15 (GDF-15) is considered to be a cardioprotective cytokine possessing antiapoptotic and antiproliferative properties. If GDF-15 plasma levels are influenced by percutanenous coronary intervention (PCI) or regular exercise training is currently not known. METHODS: After successful revascularization by PCI with stent implantation 36 consecutive patients with stable angina pectoris were randomized to an exercise training program or to a control group. Patients were followed by serial measurements of GDF-15, high-sensitivity Troponin T (hsTNT) and N-terminal pro brain natriuretic peptide (NT-proBNP) levels in peripheral blood after PCI and during six months follow-up. RESULTS:Plasma levels of GDF-15 showed an early response to PCI with a modest, but significant increase after 30 minutes (p = 0.007) peaking three hours after PCI. Levels of hsTNT rose 5-fold from baseline to 24 hours (p < 0.001) with a normalization at seven days post PCI. Changes in plasma levels of GDF-15, hsTNTand NT-proBNP were not significantly different between the training and control group during follow-up. CONCLUSIONS:GDF-15 levels show a modest transient increase in response to coronary intervention with stent implantation. Exercise training over six months does not affect plasma levels of GDF-15, hsTNT or NT-proBNP in patients with stable coronary artery disease.
