RESUMO
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.

Resumen Objetivo: Caracterizar la máxima duración de la onda P (Pmáx) y la dispersión de la onda P (DP) según las cifras de tensión arterial (TA) y los niveles de ácido úrico en pacientes geriátricos. Método: Se realizó un estudio analítico en 83 pacientes mayores de 60 años pertenecientes al Consultorio Médico de la Familia 5 del Policlínico Aracelio Rodríguez Castellón, Cienfuegos, Cuba entre enero y diciembre de 2015. La muestra se dividió en dos grupos (pacientes con hiperuricemia y pacientes con AU normal). Resultados: Existe correlación lineal y significativa entre la tensión arterial diastólica y la Pmáx en los pacientes con hiperuricemia (r=0,695; p=0,026), mas no en los pacientes con AU normal (r=0,048; p=0,757). Se demuestra correlación lineal y significativa entre la tensión diastólica y la DP en los pacientes con hiperuricemia (r=0,657; p=0,039), aunque no en los pacientes con AU normal (r=0,054; p=0,730), respectivamente. Conclusión: Existe correlación entre la Pmáx y la DP y las cifras de tensión arterial diastólica en pacientes geriátricos con hiperuricemia.
