Sleep to Lower Elevated Blood Pressure (SLEPT)

1. september 2014 opdateret af: 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.

Beskrivelse

Inclusion Criteria:

  • Signed written informed consent

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: 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.
Adfærdsmæssigt: Online Sleep Education
Ingen indgriben: Usual CV care
Specialist nurses will administer the CV risk factor education intervention to participants in small groups over one hour.
