Levels of uric acid and increased diastolic blood pressure: Risk factors for atrial fibrillation in patients older than 60 years.

OBJECTIVE To characterize the maximum P-wave duration (Pmax) and P-wave dispersion (PWD) according to blood pressure (BP) and uric acid (UA) levels in geriatric patients. METHOD An analytical study was performed in 83 patients aged over 60 years treated at the Family Medical Office 5 of the Aracelio Rodríguez Castellón Polyclinic, in Cienfuegos, Cuba between January and December 2015. The sample was divided into two groups (patients with hyperuricemia and patients with normal UA levels). RESULTS We found a linear and significant correlation between diastolic BP and Pmax in patients with hyperuricemia (r=0.695; p=0.026), but not in patients with normal UA (r=0.048; p=0.757). A linear and significant correlation was demonstrated between diastolic BP and PWD in patients with hyperuricemia (r=0.657; p=0.039), but not in patients with normal UA (r=0.054; p=0.730). CONCLUSION There is correlation between diastolic BP and Pmax plus PWD in elderly patients with hyperuricemia.
