- Brief Summary
Stress is highly prevalent in patients with ischemic heart disease (IHD) and is associated with lower health-related quality of life and worsened cardiovascular outcome. The importance of stress management is now recognized in recent cardiovascular guidelines. However, effective stress management intervention are not implemented in clinical routine yet. The development of easily disseminated eHealth interventions, particularly mHealth, may offer a cost-effective and scalable solution to this problem. The aim of the proposed trial is to assess the efficiency and cost-effectiveness of the mHealth intervention 'mindfulHeart' in terms of reducing stress in patients with IHD.
- Detailed Description
Chronic stress occurs over an extended period, from months to years, and can result in several adverse health consequences. The relationship between chronic stress and cardiovascular diseases continues to be subject of extensive research. Recent large studies have shown that chronic stress is linked to heightened risk for cardiovascular diseases (CVD), leading to its recognition in current clinical guidelines. Chronic stress was demonstrated as risk factor for the development, but also for the progression of CVD, and research has found associations between stress measurements and traditional cardiovascular risk factors. Stress is also considered as relevant player in the pathophysiological cascade of coronary atherosclerosis formation (e.g., inflammatory response, endothelial dysfunction, platelet aggregation) until the development of clinical apparent ischemic heart disease (IHD). Measures of stress have been associated with the onset and progression of further cardiovascular disorders, like coronary calcification, atrial fibrillation, and stroke. In patients with IHD, stress has also been implicated as an acute trigger of myocardial ischemia and infarction, malignant arrhythmias, and sudden cardiac death.
Although the body of evidence examining the stress-IHD connection is growing, there continues to be a lack of recognition of this association in clinical practice and of effective and scalable interventions. Desirable would be the sustainable integration of targeted therapy in cardiology practice that involves screening for stress, referral to psychological, and/or behavioral therapy or to other stress reducing interventions (e.g. meditation, holistic self-care programs, or other complementary approaches). Although ongoing group support and concomitant coaching in other lifestyle-related fields such as diet and exercise are conductive to long-term adherence, the establishment of area-wide structured stress management programs is resource-intensive and currently not available.
A potential solution to cost-prohibitive stress reduction programs is the development of easily disseminated eHealth intervention, which can be effective and scalable, and easier to implement in the context of a busy clinical practice. The term "eHealth" encompasses a wide range of electronic solutions, such as mobile phones (mHealth) and computers that can enhance and broaden the scope of medical care.
Especially mHealth interventions are perceived to offer several advantages that may overcome some of the limitations of face-to-face approaches, including anonymity, 24/7 availability, reduced costs in terms of traveling to courses for both participants and instructors, high scalability, and a low access threshold. Enabling participants to be reached earlier than in classical face-to-face trainings, such interventions may have the potential to prevent even the onset of more severe chronic stress or mental health problems. The effectiveness of eHealth interventions for stress reduction was shown in a recent meta-analysis.
The link between stress and increased mortality and morbidity in CVD is obvious and includes also an undeniable reduction in health-related quality of life (HRQoL). This lead to the fact that the search for novel therapeutic strategies is inevitable. Therefore, the investigators aim in the current study to evaluate the efficacy and cost-effectiveness of the digital stress management intervention 'mindfulHeart' in terms of sustainable stress reduction in the target population.

- Primary Outcome Measures
Name Time Method combined global stress measure 3 months, after intervention The outcome is based on a published RCT in Circulation by Blumenthal et al. \[34\]. A global stress measure (mean rank), was the primary outcome combining the following components at baseline and following treatment: Beck Depression Inventory II, Spielberger Anxiety Inventory-State, General Health Questionnaire, PROMIS Anger Questionnaire, and Perceived Stress Scale. A range from 1 to 147 was present with higher scores suggestive of better function. The change in each individual scaled score is presented in primary outcome 2. (see also NCT00981253)
- Secondary Outcome Measures
Name Time Method Health-related quality of life Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months we will apply two instrument to measure health-related quality of life. Namely the Short Form-36 health questionnaire and the European Quality of Life 5 Dimensions 5 Level survey (EQ-5D-5L) \[36,37\]. The SF-36 is an eight-dimensional scale consisting of 36 items. It assesses health-related quality of life based on physical, social, and psychological functioning, role behavior due to physical and psychological functional impairment, physical pain, general health perception, and vitality. The EQ-5D-5L consists of five health-related dimensions that can be assessed at five levels. In addition, the questionnaire contains a visual analog scale for assessing general health
Disease-specific effect of angina on patients' physical function and quality of life Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months We will also include the Seattle Angina Questionnaire (SAQ). The 7-item version of the SAQ is a shortened version of the original 19-item SAQ and has been shown to be highly valid, reliable, and sensitive to clinical change. These ranges of SAQ scores are strongly and independently correlated with the risk of subsequent death, the risk of myocardial infarction, and health care costs
Changes in functional capacity Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months changes in functional capacity will be recorded using the established 6-minute walk test
Blood pressure Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months To evaluate the effect of the intervention on blood pressure , this parameters will be assessed with the average of three consecutive measurements at rest. The standard measurement approach was always performed in the same quiet room at a consistent controlled temperature and after a resting period of at least 20 minutes. The same examination sequence was maintained for all study subjects. To obtain reliable measurements, the patients were asked not to speak and to lie quietly during the entire measurement.
Heart rate Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months To evaluate the effect of the intervention on heart rate , this parameters will be assessed with the average of three consecutive measurements at rest. The standard measurement approach was always performed in the same quiet room at a consistent controlled temperature and after a resting period of at least 20 minutes. The same examination sequence was maintained for all study subjects. To obtain reliable measurements, the patients were asked not to speak and to lie quietly during the entire measurement.
Self-efficacy Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months To evaluate self-efficacy, we will utilize the Generalized Self-Efficacy Scale (GSES) in its German version \[41\]. The GSES is a self-administered questionnaire that measures an individual's optimistic self-beliefs and self-efficacy in dealing with challenging demands and stressful events in life. Each of the 10 items is rated on a 4-point Likert scale.
combined global stress measure Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months The outcome is based on a published RCT in Circulation by Blumenthal et al. \[34\]. A global stress measure (mean rank), was the primary outcome combining the following components at baseline and following treatment: Beck Depression Inventory II, Spielberger Anxiety Inventory-State, General Health Questionnaire, PROMIS Anger Questionnaire, and Perceived Stress Scale. A range from 1 to 147 was present with higher scores suggestive of better function. The change in each individual scaled score is presented in primary outcome 2. (see also NCT00981253)
Depression symptoms (BDI-II) Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months The BDI-II is a self-report questionnaire comprising 21 items that assess depression severity. Its reliability and validity have been established through various studies among diverse populations and cultural backgrounds. Higher scores indicates increased depression symptoms
Anxiety symptoms (STAI) Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months The STAI is the most authoritative tool for assessing anxiety in adults, precisely distinguishing between transient "state anxiety" and persistent "trait anxiety". The STAI measures anxiety with 20 items and has a range of 20 to 80. A higher score indicates more pronounced anxiety
PROMIS-Anger Scale Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months The PROMIS Anger scale comprises eight items that evaluate various aspects of anger. Scores on the scale range from 8 to 40, with higher scores indicating greater levels of anger
GHQ Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months The GHQ assesses general distress and consists of 12 items. Respondents' scores range from 0 to 36, where higher scores correspond to increased distress
Perceived Stress Scale Baseline, after 3 months, after 4 months, after 6 months, after 9 months, after 15 months The Perceived Stress Scale-10 item version is a short tool for the assessment of how individuals perceive stress in their lives. The values range from 0 to 40. Higher values indicate higher perceived stress \[46\].
(l) In-treatment assessments: at the start of each intervention module (weekly), the following assessment instruments will be applied: Distress Thermometer (DT), Patient Health Questionnaire-4 (PHQ-4) and self-generated measures to assess coping skills and self-efficacy
