Study type: Interventional

Summary: 
      Sleep-wake disturbances were found to be a common problem among patients with CHD either
      earlier during hospitalization or/ and after discharge Although there is an evidence that
      sleep-wake disturbanes occur in high rate among patients with CHD little was found about
      assessment and management of this problem. This randomized controlled study will assess sleep
      quality of stable CHD patients who were admitted for undergoing coronary angiography
      electively. Then it will test the hypothesis that atlas cedar wood essential oil aromatherapy
      have a positive effect on sleep quality of CHD patients.
    

Detailed description:

      asleep, staying asleep, inadequate sleep duration, dissatisfaction with a sleep and excessive
      daytime sleepiness) among recruited CHD patients.

      - data were collected by two phase:

        -  phase one: sleep quality of recruited CHD patients, who were admitted for undergoing
           coronary angiography electively, were assessed using Pittsburg Sleep Quality Index
           (PSQI). CHD participants who were reported poor sleep quality (=>5) in PSQI score will
           randomly allocated by toss either to intervention or control group.

        -  Phase two:

             1. Intervention group received an atlas cedar wood aromatherapy for five consecutive
                nights.

             2. Control group received no intervention.

             3. Sleep quality of both group participants re-assessed at second day and six day of
                recruitment, respectively, using PSQI.
