M-Health Care for Patients After AMI on Disease Perception, Self-Efficacy, Anxiety and Cardio-Respiratory Fitness

Effects of Mobile Health Care for Patients After Acute Myocardial Infarction on Disease Perception, Self-Efficacy, Anxiety and Cardio-Respiratory Fitness: A Randomized Controlled Trial

The aim of this study is to explore the overall effectiveness of interventions using mobile health care to improve disease perception, self-efficacy, anxiety, cardio-pulmonary fitness for patients with acute myocardial infarction.

Heart disease is the second leading cause of death in Taiwan. Coronary artery disease (CAD) is the majority, and coronary artery disease is the most common cardiovascular disease. There is an increase, and it is no longer just that the elderly is the predominant group. There is a tendency to gradually become younger. In foreign countries, coronary heart disease is also one of the main causes of patient death and disability, resulting in huge medical burdens and costs. Coronary heart disease also includes acute myocardial infarction, which causes myocardial cell death due to unstable myocardial ischemia. Sudden heart disease brings unexpected shock, fear, and despair to patients and their families. Therefore, patient self-management is very important. It also improves the patient's quality of life.

Post-acute myocardial infarction patients are susceptible to piecemeal information and lack the motivation to change their life style, continue to maintain smoking behavior and do not engage in exercise, leading to the recurrence of major coronary artery problems. In order to reduce secondary cardiovascular problems, it is necessary to rely on the patient's own knowledge of the disease, self-care behavior and self-efficacy, including diet, exercise, etc., so that the disease can be controlled and treated, and also need to monitor and adjust the physical and mental state to reduce subsequent problems caused by anxiety. Therefore, in order to provide multi-party support for patients' self-health care, mobile health care such as mobile phone text messages, applications, and remote monitoring are gradually emerging. Therefore, it is expected that the use of mHealth can be used to develop two-way communication and interaction and a higher message reception rate to stimulate acuteness. After myocardial infarction, patients can change their motivations for self-health care behaviors to achieve more efficient disease perception, self-efficacy, anxiety and cardiopulmonary fitness, and have a longer-term influence ability.
