Sleep to Lower Elevated Blood Pressure (SLEPT)
1 de septiembre de 2014 actualizado por: Dr. Emer McGrath, University College Hospital Galway
Sleep to Lower Elevated Blood Pressure: A Randomised Controlled Trial
Sleep is an essential component of good physical and mental health.
Previous studies have reported that poor quality sleep is associated with an increased risk of hypertension, stroke and cardiovascular disease (CVD).
Hypertension is the most common and important risk factor for CVD, and even modest reductions in blood pressure result in significant reductions in stroke and myocardial infarction.
In this randomised trial, the investigators aim to evaluate whether a simple, multi-component, online sleep intervention reduces blood pressure in patients with essential hypertension.

Experimental: Online Sleep Education
The sleep intervention is a multi-component online intervention consisting of sleep information and sleep hygiene education, along with behavioural and cognitive components.
|
|
|
Sin intervención: Usual CV care
Specialist nurses will administer the CV risk factor education intervention to participants in small groups over one hour.
