This study investigates health behaviour and readiness for lifestyle change in patients who recently had a heart attack (myocardical infarction) treated with stenting (PTCA). Despite successful acute treatment, many patients remain at increased risk of a second heart atttack because lifestyle changes are not consistently maintained. Participants who had a heart attack within the past 6 months will complete standardized questionnaires on readiness to change, quality of life, anxiety/depression, and physical functioning, plus a free-text section on personal barriers to change. Findings will characterize this population and inform a future lifestyle intervention trial
Cardiovascular diseses are the leading cause of deaths in Germany and worldwide. Even after successfull PTCA, reinfarction rates remain elevated, partly because patients often underestimate their ongoing risk, have limited knowledge of secondary prevention targets and show low self-efficacy for behavior change; anxiety and depression are also common after myocardial infarction. This single-center, cross-sectional study enrolls patients treated with PTCA within the past 6 months, recruited during their routine follow-up visit at the Lipidambulanz, Westdeutsches Herz- und Gefäßzentrum, University Hospital Essen. Participants complete validated questionnaires: PIAC (primary outcome; rediness to change), SF-36 (quality of life); HADS (anxiety/depression), and KCCQ-23 (physical functioning), plus sociodemographic data and free-text section on perceived barriers. This study is purely observational, involves no interventions or biospecimens and takes about 30 minutes. A sample of 143 participants was calculated for adequate precision in estimating the PIAC meand and supporting exploratory regression analyses, accounting for 10% dropout. Data collection runs 6 months, followed by 18 months of analysus. Results wull inform a planned randomized controlled trial.

PIAC (Perception, Intention and Ability to Change) Scale
Readiness and ability to change health-related behavior, habits and living conditions, assessed using the PIAC questionnaire, a validated 9 item instrument covering awareness of negative health behaviors, intention to change and implementation of change strategies. Higher scores indicate a better awareness and intention to change.
Time frame: Single assessement at study enrollment, baseline
SF-36 (Short-form 36 Health Survey)
Health-related quality of life assessed using the SF-36, yielding a physical and a mental summary score; higher scores indicate better quality of life.
Time frame: Single assessement at study enrollment, baseline
HADS (Hospital Anxiety and Depression Scale)
Anxiety and depressive Symptoms assessed using the HADS(-A) for Anxiety and HADS-(D) for depression. each ssubscales ranges from 0-21; higher scores indicate greater severity.
Time frame: Single assessement at study enrollment, baseline
KCCQ-23 (Kansas City Cardiomyopathy Questionnaire)
Disease-specific health status using the KCCQ-23 covering physical limitations, symptoms, self-efficacy, social limitation and quality of life. Scores ranging 0-100 with higher scores indicating better health status.
Time frame: Single assessement at study enrollment, baseline
