Transcripción

1 CONCLUSIONES 1.- La ingestión de aguas minerales bicarbonatadas sódicas con diferentes concentraciones de minerales no aumenta la PA en pacientes mayores con HTA grado I 2.- El grado de mineralización del agua y el aumento de la PA muestran una relación inversa, ya que las mayores concentraciones de bicarbonato sódico, calcio, potasio y magnesio, tienen un efecto protector contra el aumento de PA al final del periodo de intervención, con efectos independientes de la PA y de la excreción de minerales urinarios al inicio del estudio. 3.- Nuestros datos confirman que la sensibilidad de la PA al cloruro sódico, depende de ambos, sodio y cloruro, y que la ingesta de sales no cloradas de sodio, como el bicarbonato sódico no sólo presenta un efecto menor que el cloruro sódico sobre la PA, sino que protege contra su elevación. 4.- Los estudios epidemiológicos y clínicos sugieren que la dietas bajas en potasio o calcio amplifican el efecto de la ingesta elevada de cloruro sódico en la presión arterial. Los resultados de nuestro estudio confirman estos datos y muy probablemente esos cationes presentes en las aguas minerales en cantidades no despreciables potencien los efectos del bicarbonato. Por ello un control más riguroso sobre el balance ionico podria ser beneficioso para los hipertensos. 5.- La ingesta de aguas bicarbonatadas sódicas disminuyó la excreción urinaria de calcio, factor añadido claramente beneficioso en la población mayor hipertensa predominantemente femenina, con riesgo de osteoporosis.
