Patient-reported Outcomes in the Bergen Early Cardiac Rehabilitation Study

Study Overview
=================
Brief Summary
-----------------
An intervention study with longitudinal follow-up of patients with coronary artery disease undergoing early cardiac rehabilitation is designed.

Detailed Description
-----------------
The main objective of the study is to investigate patient-reported outcomes, their relation to clinical characteristics of the patients and the potential to predict health outcomes and adverse events in coronary artery disease patients participating in an early cardiac rehabilitation programme.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: Early cardiac rehabilitation<br>Single Group: 5 week cardiac rehabilitation programme. Pre-post comparison. | Other: Early cardiac rehabilitation<br>* This is an early cardiac rehabilitation programme starting 1-2 weeks after hospital discharge (Phase 2A rehabilitation). The programme provided by a multidisciplinary team includes individual counseling, educational sessions and discussion in groups, and exercise training sessions three days a week for five weeks. For additional analysis there will be a comparison group that did not receive the intervention for practical reasons.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to composite of total mortality, and hospitalization for heart failure and atherothrombotic disease (including non-fatal MI, unstable angina and stroke). | Time to combined endpoint from inclusion. | Up to 10 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Self-reported health | The EuroQol 5-dimensions-5 level questionnaire (EQ-5D-5L) is an 5 item self-report-questionnaire assessing self-reported health. The respondent rates each item on a 5-point scale ranging from 1(indicating no problem) to 5 (indicating extreme problems). This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. | Immediately after the 5 week intervention, and at 9, 31, 57 and 109 weeks | 
| Change in self-reported global health | The VAS scale from the EQ-5D-5L assess global health. The scale goes from 0 to 100 were lower score indicates worse health. | Immediately after the 5 week intervention, and at 9, 31, 57 and 109 weeks | 
| Change in post traumatic growth | The Posttraumatic Growth Inventory-Short Form (PTGI-SF) is a 10 item scale measuring post traumatic growth. The respondent rates each item on a 6-point scale ranging from 0 (I did not experience this change as a result of my crisis) to 5 (I experienced this change to a very great degree as a result of my crisis). The scale is scored by adding all the responses.Individual factors are scored by adding responses to items on each factor. Factors are indicated by the Roman numerals after each item. | Immediately after the 5 week intervention, and at 9, 31, 57 and 109 weeks | 
| Nicotine dependence | The Fagerström test | Immediately after the 5 week intervention, and at 9, 31, 57 and 109 weeks | 
| Change in anxiety and depression | The Hospital Anxiety and Depression Scale (HADS) is a fourteen item scale where seven of the items relate to anxiety and seven relate to depression. The respondent rates each item on a 4-point scale ranging from 0 (absence) to 3 (extreme presence). The total score is 42 (21 per subscale). | Immediately after the 5 week intervention, and at 9, 31, 57 and 109 weeks | 
| Change in physical and mental dimensions of health | The Short Form Health Survey (SF-12) include 12 items with 3 to 5 response levels. It generates two health indices: mental health and physical health. The score range between 0 and 100, with 100 representing the highest level of health | Immediately after the 5 week intervention, and at 9, 31, 57 and 109 weeks | 
| Change in health status following myocardial infarction | The Myocardial Infarction Dimensional Assessment Scale (MIDAS) is a PRO measure developed and validated to specifically measure the health status of individuals who have suffered a myocardial infarction. It consist of 7 domains, and is a 35 item scale where respondents rate each item on a 5-point scale ranging from 1 (never) to 5 (always). The function of the MIDAS is to indicate the extent of ill health in each of the seven domains assessed, therefore each dimension is scored separately using a simple scoring methodology. | Immediately after the 5 week intervention, and at 9, 31, 57 and 109 weeks |
