Effect of Guided Imagery on Sleep Quality, State Anxiety, and Comfort in Patients With Acute Coronary Syndrome

27 agosto 2026 aggiornato da: ÖZNUR GÜRLEK KISACIK, Afyonkarahisar Health Sciences University

The Effect of Guided Imagery on Sleep Quality, State Anxiety, and Comfort Levels in Patients With Acute Coronary Syndrome Monitored in a Cardiac Intensive Care Unit

The goal of this randomized controlled trial is to determine whether guided imagery, when added to routine care, can reduce state anxiety and improve sleep quality and comfort in adults with acute coronary syndrome who are being treated in a cardiac intensive care unit.

The main questions this study aims to answer are:

Does guided imagery reduce state anxiety compared with routine care alone? Does guided imagery improve sleep quality compared with routine care alone? Does guided imagery improve comfort compared with routine care alone?

A total of 64 participants will be randomly assigned to either a guided imagery group or a routine care group using block randomization.

Participants in the guided imagery group will receive routine care and listen to a standardized guided imagery audio recording through headphones twice a day for two consecutive days. Each guided imagery session will last approximately 15 minutes. Participants in the routine care group will receive the standard treatment and nursing care provided in the cardiac intensive care unit without guided imagery.

Researchers will assess participants' anxiety, sleep quality, and comfort and compare the changes between the two groups.

Descrizione dettagliata

Acute coronary syndrome is a serious cardiovascular condition that often requires monitoring and treatment in a cardiac intensive care unit. During intensive care, patients may experience anxiety, sleep disturbance, and reduced comfort because of the acute nature of the illness, the unfamiliar environment, monitoring equipment, noise, interruptions, and ongoing treatment and nursing procedures. Guided imagery is a non-pharmacological mind-body intervention that uses verbal guidance to help individuals focus their attention on calming and relaxing mental images. This study will examine whether adding guided imagery to routine cardiac intensive care can improve patient-reported outcomes in adults with acute coronary syndrome.

This study is designed as a randomized controlled trial with two parallel groups. Eligible participants will be allocated in a 1:1 ratio to either a guided imagery group or a routine care group using block randomization. Participants in both groups will continue to receive the routine medical treatment and nursing care required for their clinical condition.

Participants assigned to the guided imagery group will additionally listen to a standardized guided imagery audio recording through headphones twice daily for two consecutive days. One session will be scheduled during the daytime and one during the evening. Each session will last approximately 15 minutes. The audio recording includes a brief relaxation preparation, attention to natural breathing, visualization of a safe and peaceful environment, and calming sensory imagery. Participants will remain in a clinically appropriate and comfortable position during the intervention and may stop the session at any time if they experience discomfort.

The study will evaluate changes in state anxiety, sleep quality, and comfort over the study period. State anxiety will be evaluated both as an overall patient-reported outcome and, using a brief numerical rating, immediately before and after the guided imagery sessions to explore short-term changes associated with individual sessions. Sleep quality will be assessed after each of the two study nights, and comfort will be assessed before the intervention period and after completion of the two-day study period.

To reduce assessment bias, outcome measurements will be performed by a trained nurse who is independent of the intervention and blinded to group allocation. The study is intended to determine whether guided imagery can be used as a simple, non-pharmacological nursing intervention to support psychological comfort, sleep, and anxiety management in patients with acute coronary syndrome receiving care in a cardiac intensive care unit.

Change in Comfort as Measured by the General Comfort Questionnaire-Short Form (GCQ-SF)
Lasso di tempo: Baseline (Day 1, before the first intervention) and Day 3 morning after completion of the two-day intervention period
Comfort will be assessed using the General Comfort Questionnaire-Short Form (GCQ-SF), a 28-item self-report measure rated on a 6-point Likert scale. Negatively worded items are reverse scored, and an overall mean score ranging from 1 to 6 is calculated. Higher scores indicate greater perceived comfort. The GCQ-SF will be administered at baseline before the first intervention and again on the morning of Day 3 after completion of the two-day intervention period. The two measurements will be used to evaluate the effect of guided imagery compared with routine care on overall comfort.
Baseline (Day 1, before the first intervention) and Day 3 morning after completion of the two-day intervention period
Immediate Anxiety as Measured by the Numerical Rating Scale for Anxiety (NRS-A)
Lasso di tempo: Immediately before and within 5 minutes after each daytime and evening session on Days 1 and 2
Immediate anxiety will be assessed using the Numerical Rating Scale for Anxiety (NRS-A), a single-item self-report measure ranging from 0 to 10. A score of 0 indicates no anxiety and a score of 10 indicates the most severe imaginable anxiety, with higher scores indicating greater immediate anxiety. NRS-A will be administered immediately before and within 5 minutes after each daytime and evening session on Days 1 and 2. These pre- and post-session measurements will be used to evaluate the short-term effect of each guided imagery session on immediate anxiety compared with routine care.
