In the group-wise comparisons, patients with an incident fracture were older and had a higher prevalence of atrial fibrillation (AF) (Table 1) and performed more poorly in the maximal ergometry test (data available in 174 patients) (Table 2) and presented higher values of TnT and ProBNP and ferritin, but lower triglycerides. This evidence concerns the gene NPPB and atrial fibrillation.
