Brief summary
The study will assess the efficacy of a web-based application as a complement to traditional exercise-based cardiac rehabilitation for improvement of secondary prevention outcomes in post-myocardial infarction patients, compared with usual care. The hypothesis is that the intervention enhances patient adherence to lifestyle advice (exercise training, daily physical activity, healthy diet and tobacco abstinence) and medication, resulting in better risk factor control and prognosis as well as increased self-rated health.
Detailed description
It is well documented that participation in cardiac rehabilitation (CR) programs improves risk factor control and therapy adherence, enhances quality of life and reduces recurrent events. However, the current incomplete fulfilment of guideline recommended CR targets is a matter of concern. Also, while international recommendations advocate program flexibility and individual tailoring, most of the current CR programs are rigid, time-limited and demand substantial health care resources. Therefore, all main international heart associations have claimed for the reengineering of CR to enhance access, adherence, and effectiveness. The general call is for the development of innovative and cost-effective CR programs oriented to modify lifestyle and behaviour with sustainable results and that may be easily integrated in the pre-existing health care structures.eHealth i.e. the use of electronic communication and information technologies in health care, offers a whole new array of possibilities to provide clinical care. These include for example distance monitoring via telecommunication and sensors, interactive computer programs and smart phone applications. While there are thousands of available eHealth applications on the market, only a small minority have been tested in a controlled manner with proper guidance from health care personnel. The study will assess the efficacy of a web-based patient support application as a complement to traditional exercise-based CR for improvement of secondary prevention outcomes in post-MI patients, compared with usual care. The hypothesis is that the intervention enhances patient adherence to lifestyle advice (exercise training, daily physical activity, healthy diet and tobacco abstinence) and medication, resulting in better risk factor control and prognosis as well as increased self-rated health. A secondary hypothesis is that complementing the application with an activity tracker (accelerometer in a smart bracelet) will enhance the effect of the intervention.
Interventions
OTHERLifePod®
The software is a web-based application designed to support persons adhering to lifestyle advice and medication. The patient can log information about lifestyle (i.e. diet, exercise, and smoking), measurements (i.e. weight, pulse and blood pressure), symptoms and medication and can review data in graphs displaying registered values in relation to recommended targets. The software provides positive feedback on healthy choices and gives general recommendations on exercise training, physical activity and healthy diet. Reminders are generated in the case of decreasing registrations. Finally, short text messages (SMS) will be sent out 2-3 times a week with tips on healthy lifestyle.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in submaximal exercise capacity in watts (W) | Change between first (2-4 weeks post-MI) and second (4-6 months post-MI) submaximal exercise test conducted at physiotherapist visits | Submaximal exercise capacity reflects the patients´ level of physical fitness.The submaximal exercise test is performed on a bicycle ergometer according to the World Health Organisation (WHO) protocol, with an increased workload of 25W every 4.5 minutes The initial starting load, 25W or 50W, is decided, based on the patient's exertion history. After two and four minutes of each workload; heart rate, rate of perceived exertion according to Borg's rating of perceived exertion scale (RPE) and subjective symptoms, including chest pain and dyspnea according to Borg's Category Ratio Scale, CR-10, scale are rated. After three minutes, the systolic blood pressure is registered. The exercise test is discontinued at Borg RPE 17 and/or dyspnea 7 on Borg's CR-10 scale. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in healthy diet index | Change between baseline, first (6-8 weeks post-MI) and second (12-14 months post-MI) nurse visits post-MI | The healthy diet index is a four-item questionnaire used to evaluate dietary habits within the Swedish Secondary Prevention after Heart Intensive Care Admission (SEPHIA) registry |
