Comprises 35 items specifically measuring seven different domains of health status and daily life challenges in individuals who have suffered a myocardial infarction: physical activity (12 items), insecurity (9 items), emotional reaction (4 items), dependency (3 items), diet (3 items), concerns over medication (2 items) and side effects (2 items). 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.

SAQ-7 assesses patients' symptoms of chest pain, functioning, and quality of life through. The SAQ-7 is scored by transforming responses to seven items into three domains-Physical Limitation (PL), Angina Frequency (AF), and Quality of Life (QoL)-scaled from 0-100, where higher scores indicate better health. Items are coded 1-6 (worst to best), summed, and transformed. A total summary score is the average of these three domains

Comprises 12 items with 3 to 5 response levels. It generates two health indices: mental and physical health. A score of 50 represents the average US population, while scores above or below indicate better or worse health, respectively.

Comprises one global item on overall quality of life scored on a 1-5 Likert scale, ranging from "Very poor/dissatisfied" (1) to "Very good/satisfied" (5)

Comprises 16 items and is a self-reporting tool for identifying modifiable adherence barriers among individuals prescribed post-myocardial infarction secondary prevention medicines in clinical practice. The questionnaire uses a 4-point Likert scale (strongly agree, agree, disagree, strongly disagree) for sections 2-5, which focus on understanding, concerns, practical barriers, and routine. Adherence Assessment (Section 6): A 5-point Likert scale is used to assess adherence to individual secondary prevention medicines over the past month (e.g., all of the time, nearly all of the time, most of the time, about half the time, less than half the time).

Serum levels of cardiac medications (quantified using liquid chromatography with mass spectrometry).

EQ-5D-5L is an 5 item (plus a VAS scale) self-report-questionnaire assessing self-reported health. Each question has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. 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.

Smoking status (smoker, previous smoker, never smoker)

Comprises 14 items and determine the levels of anxiety and depression that a patient is experiencing, and generates 2 sub-scales; HADS-D and HADS-A. HADS-Anxiety and/or HADS-depression score ≥/< 8

Comprises 16 items covering eight topic areas: heart condition explained, communication among providers, preparation for discharge, post-hospital review of treatment, receipt of conflicting information, information on medications and on physical and dietary needs. Respondents rate each item on a 6-point scale ranging from 1 (strongly disagree) to 5 (strongly agree) or 6 (not applicable).

Comprises 20 items measuring four levels of health literacy: Appraisal of health information (5 items); social support for health (5 items); Ability to find good information (5 items); and Understanding health information (5 items). Each score provides insight into the strengths and limitations of the respondent, but the scores are most powerful when viewed together to show the 'health literacy profile' of the respondent.

The eHealth Literacy Scale (Eheals) is an 8-item measure of eHealth literacy developed to measure consumers' combined knowledge, comfort, and perceived skills at finding, evaluating, and applying electronic health information to health problems. Respondents indicate their agreement with statements on a 5-point Likert scale ranging from 1 (Strongly Disagree) to 5 (Strongly agree).

The Sleep Sufficiency Index (SSI) is calculated by dividing an individual's actual habitual sleep duration by their estimated needed sleep duration. It measures whether a person is getting enough sleep to feel rested, based on their personal requirements rather than a set number of hours. SSI >0.8: Classified as having sufficient sleep, provided the total duration is also > 6 hours. SSI < 0.8: Classified as having insufficient sleep, even if total sleep time is relatively high.

The Minimal Insomnia Symptom Scale (MISS) is scored by summing the responses to three items covering difficulty falling asleep, staying asleep, and waking too early. Each item is rated on a 5-point scale (0-4), resulting in a total score from 0 to 12. A score of ≥6 is generally used as the cut-off to identify clinical insomnia in adults.

VO2peak, Self-reported intensity adjusted minutes, activity monitoring

Visceral fat, muscle mass, body fat, BMI

Charlson Comorbidity score ≥/< 5

The Clinical Frailty Scale (CFS) is scored on a 1-9 scale based on clinical judgment of a patient's baseline functional status. It assesses mobility, function, cognitive ability, and comorbidities, ranging from 1 (Very Fit) to 9 (Terminally Ill)

The Digital Health Readiness Questionnaire (DHRQ) is scored by summing responses from four main domains (15-75 range) using a 5-point Likert scale (1=Strongly Disagree, 5=Strongly Agree). A higher score indicates greater digital readiness.

A visual analog scale ranging from 0 (fatigue is not a problem) to 10 (fatigue is a major problem) is used to measure change in fatigue

The diet section of the Trøndelag Health Study (HUNT3) is scored based on self-reported questionnaires-specifically, a short food frequency questionnaire (FFQ) designed to measure adherence to Norwegian dietary recommendations. The scoring typically translates frequency of intake into a diet quality index or a total adherence score, often based on a 0-5 or higher scale, where higher scores represent a healthier diet

The Study of Osteoporotic Fractures (SOF) index will be used to measure frailty status. The SOF index includes three items: 1) weight loss > 5% in the last year, 2) inability to rise from a chair five times without using arms, and 3) reduced energy level. The questions have dichotomous response alternatives (yes/no). Patients who meet none of these criteria will be considered robust, one of the criteria are pre-frail, and two or three of these criteria are considered frail.

14-item, heart-specific tool (for ischemic heart disease) scored on a 4-point Likert scale, ranging from 0 ("A lot") to 3 ("Not at all"). It measures physical (10 items) and emotional (4 items) quality of life, where higher mean scores (0 to 3) indicate better health-related quality of life

The Beliefs about Medicines Questionnaire (BMQ) assesses beliefs and perceptions about medicines and treatment. The BMQ comprises two sections: the BMQ-Specific which assesses representations of medication prescribed for personal use and the BMQ-General which assesses beliefs about medicines in general. The two sections of the BMQ can be used in combination or separately. Respondents rate 11 items on a 5-point scale ranging from 1 (strongly agree) to 5 (strongly disagree).
