Brief summary
Acute coronary syndrome (ACS) is one of the most important causes of mortality and morbidity all over the world. Cardiac rehabilitation (CR) is a crucial part of secondary prevention and optimal care of patients with ACS. However, the participation rate in CR after ACS is far from expected. In our study, we will aim to examine the rate of participation in cardiac rehabilitation and the factors affecting it in patients followed up for acute coronary syndrome in the coronary intensive care unit of our hospital. Our main hypothesis is that the lower rate of participation in cardiac rehabilitation in patients with acute coronary syndrome is associated with one or more of that older age, female gender, multimorbidity, poor functional capacity, lower health literacy level or quality of life levels.
Detailed description
Acute coronary syndrome (ACS) is an umbrella term comprising unstable angina, myocardial infarction (MI) with or without ST-segment elevation, and sudden cardiac death because of acute myocardial ischemia. ACS is one of the most important causes of mortality and morbidity all over the world. Today, cardiac rehabilitation has become an integral part of the medical care and secondary prevention programs of cardiovascular diseases including ACS. Cardiac rehabilitation (CR) is a long-term comprehensive rehabilitation program that includes but not limited to patient evaluation, determination of risk profile, patient-tailored exercise training, and behavioural and lifestyle changes aiming at risk reduction in cooperation with many disciplines. It consists of comprehensive interventions. Despite its known benefits and recommended in national and international guidelines, the participation rate in cardiac rehabilitation is lower than expected. Studies involving different countries and societies showed that lower participation was associated with inadequate referral, female gender, poor motivation, older age, comorbidities, difficulty in transportation, and poor socioeconomic status. It has been suggested that setting up a CR appointment before discharge via clinical visits by the CR team or automatic referral systems, increasing patient interest and knowledge through written invitations and brochures, and providing support for transportation may increase participation in CR. In our country, there are not enough studies addressing the success of participation and compliance in cardiac rehabilitation. In this study, we aim to determine patient related factors associated with low participation in CR in patients admitted to our coronary intensive care unit (ICU) with ACS diagnosis. All patients included in this study will be comprehensively informed about CR and the initial CR session will be scheduled to minimize effect of inadequate referral.
Interventions
BEHAVIORALInvitation to the CR
1. Oral and written information emphasise the benefits of cardiac rehabilitation in terms of treatment of heart diseases, increasing functional capacity, reducing morbidity and mortality, and enhancing secondary prevention. 2. Introducing the scope and method of administration of CR to patients. 3. Setting up the appointment for the initial CR session four weeks later.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate of participation in the CR | Four weeks after discharge from ICU | Number of patients admitted to the first CR session four weeks after discharge from the ICU |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Measurement of hand grip strength | At initial evaluation of the participant in ICU | Hand grip strength is an important indicator of overall muscle strength. Measurements will be performed using a Jamar dynamometer, while sitting, with the arm just next to the trunk, the elbow flexed to 90 degrees, and the forearm and wrist in a neutral position, as recommended by the American Association of Hand Therapists. Three measurements will be performed, including one-minute intervals between trials. The highest result of the three trials will be accepted. |
| Two minute Step Test | At initial evaluation of the participant in ICU | This test is used to evaluate the endurance of lower extremity muscles. The patient is asked to stand next to a wall. The midpoint of the distance between the patient's iliac crest and the knee is measured and marked on the wall. On the signal go the patient begins stepping (not running) in place, raising each knee to the mark on the wall, as many times as possible in the 2 minutes. The number of times the right knee reaches the required height is counted. If the proper knee height cannot be maintained, the patient is asked to slow down or to stop until he/she can regain the proper form, while keeping the stopwatch running. |
| Timed Up and Go Test | At initial evaluation of the participant in ICU | It is a test that evaluates balance, mobility and lower extremity muscle strength, which includes getting up from a chair, walking 3 meters, turning back and sitting on the chair again. After an adaptation trial, the test is performed twice, including a rest period between trials. Patients are allowed to use any assistive device such as a cane or walker. The main result is the average duration of the two trials. A longer test time indicates worse performance. |
| Turkish Health Literacy Scale-32 | At initial evaluation of the participant in ICU | Turkish Health Literacy Scale-32 (Türk Sağlık Okuryazarlık Ölçeği in Turkish) is a survey comprising 32 questions that measure health literacy. It is derived from the Turkish version of The European Health Literacy Survey, which consists of 47 questions. It has been reported to be valid and reliable in Turkish population. The survey addresses accessing, understanding, evaluating and using/applying health-related information. Each question is answered by choosing one of the options very easy, easy, difficult very difficult or I don't know, corresponding to 4, 3, 2, 1 and null points, respectively. The mean score is calculated after excluding questions with invalid or I don't know answers. The index is determined following the formula index = (mean score - 1) x (50/3) A score of 0-25 indicates insufficient, \>25 to 33 indicates limited, \>33 to 42 indicates adequate, and \>42 to 50 indicates excellent health literacy. |
| Cardiac Rehabilitation Barriers Scale-Turkish Version | Four weeks after discharge from ICU | It is a questionnaire that aims to determine the reason(s) for not attending or missing the CR sessions. Each of the 21 possible reasons is answered by the patient on a 1-5 Likert scale (strongly disagree-disagree-decided-agree-strongly disagree). The last question has an open-ended answer option for patient to report other reasons. Turkish version of this survey were found to be valid and reliable by Coşkun et al. in 2019. Patients who do not attend to their CR appointment at fourth week after discharge will be called and the Cardiac Rehabilitation Barriers Scale-Turkish Version will be applied. |
| World Health Organization Quality of Life Scale-Short Form | At initial evaluation of the participant in ICU | This scale is used for a brief assessment of the quality of life in routine clinical practice, large-scale epidemiological studies, or clinical trials. It comprises 27 questions that evaluate general health status, physical health, psychological status, social relations and environmental issues sub-titles. Each question receives an answer corresponding to 1-5 points. The percentages of the scores obtained from each sub-title allow us to make a quantitative interpretation of domains of the quality of life. |
