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

Niveles de ácido úrico y presión arterial diastólica elevada: factores de riesgo de fibrilación atrial en pacientes mayores de 60 años

Summary

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.
