Abstract

Objetivos: Analizar asociación entre el índice patológico de PLMS y la PA de 24 horas, en pacientes normotensos. Evaluar la asociación entre índice patológico de PLMS, con alteraciones en la velocidad de onda de pulso y frecuencia cardíaca.

Métodos: Estudio observacional de casos y controles. Se estudiaron 19 sujetos normotensos mediante Polisomnografía Nocturna y Monitoreo Ambulatorio de la Presión Arterial. Se determinaron las variables: Edad, sexo, peso, índice de masa corporal. La presión arterial y frecuencia cardíaca de 24 hs, diurna y nocturna se evaluaron con monitoreo ambulatorio de presión arterial de 24 h. Se excluyeron pacientes con índice de apneas/hipopneas ≥ 5 e/h. Se describieron las variables y compararon sujetos con y sin PLMS, considerando significativo una p<0,05, además análisis de correlación.

Resultados: Se estudiaron a 11 pacientes con PLMS patológico y 7 controles (Índice PLMS 35,6±15 versus 7,9±5 respectivamente). Los pacientes con PLMS fueron más jóvenes 57 ±14 versus 64±6; p=0,284 años. La presión arterial de 24 h, fue menor en el grupo PLMS que en los controles (sistólica 114,2±11 versus 123±11; p=0,095; y diastólica 65,7±5 versus 74,4±11, p=0,027).

Conclusión: Encontramos una relación estadísticamente significativa, inversa, no esperada, al correlacionar los movimientos periódicos de piernas durante el sueño, de grado patológico, con la presión arterial sistólica y media de 24 h, la presión arterial sistólica diurna y nocturna, y la presión arterial media nocturna, como así también hallazgos similares en la presión de pulso de 24 horas y la presión de pulso diurna y nocturna que fueron inferiores al grupo control. No encontramos cambios en la frecuencia cardíaca.
