Sleep to Lower Elevated Blood Pressure (SLEPT)

1 settembre 2014 aggiornato da: 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.

Descrizione

Inclusion Criteria:

  • Signed written informed consent
  • ≥18 years on entry to study
  • Average automated Systolic Blood Pressure (SBP) monitor readings between 130 - 160 mmHg with average automated Diastolic Blood Pressure(DBP) monitor readings <110 mmHg on three occasions, measured in a valid standardized manner while seated, or average Ambulatory Blood Pressure Monitor (ABPM) SBP reading between 130-160 mmHg with average DBP reading <110 mmHg.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: 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.
Comportamentale: Online Sleep Education
Nessun intervento: Usual CV care
Specialist nurses will administer the CV risk factor education intervention to participants in small groups over one hour.
