OBJECTIVE: Stress and heart failure are associated with increased systemic levels of chromogranin A (CGA). Here we analyzed the effects of marathon running on systemic CGA levels and the association with cardiac burden and stress. METHODS: We recruited 47 lean and obese runners for a 10week training program aiming at running a marathon. Heart rates, individual fitness and marathon finishing times were monitored. CGA, proBNP and troponin T levels were analyzed by ELISA. RESULTS: We found a significant increase of CGA (+51%; p<0.01) in lean runners after marathon. The obese group showed the highest troponin T (0.22ng/ml; p<0.01) and proBNP (176.6ng/ml; p<0.01) levels. There were no correlations between proBNP, troponin T and CGA. An inverse correlation (r=-0.45; p<0.01) was found between CGA and finishing times. CONCLUSION: Marathon running is associated with increased CGA levels. However, this does not seem to reflect cardiac burden but rather marathon induced stress.
