Cardiovascular diseases (CVD) remain the leading cause of mortality globally, accounting for approximately 30% of all deaths. Despite Poland's exemplary system for managing myocardial infarctions, the country faces one of the highest mortality rates in Europe during the first year post-heart attack. This paper examines the transformative potential of integrating telemedicine and Business ProcessManagement (BPM) in the treatment of chronic diseases, with a particular focus on cardiac telerehabilitation. Through an in-depth case study of the Comprehensive Post-Myocardial Infarction Care Program (KOS-Zawal), the research demonstrates how a BPM approach supported by telemedicine can enhance treatment quality and reduce mortality rates for post-heart attack patients. The study advocates for a paradigm shift from traditional healthcare models, emphasising the importance of collaboration among healthcare professionals, patients, and caregivers. It highlights the ability of telemedicine to deliver personalised care, reduce healthcare costs, and improve patient outcomes. Cardiac telerehabilitation not only significantly lowers costs and provides greater accessibility compared to traditional rehabilitation but also provides preventive benefits, reducing the incidence of acute conditions such as heart attacks and preventing subsequent mortality or disability. Observations indicate that the KOS-Zawal program reduces the risk of death in the first year after myocardial infarction by almost 30% compared to standard care. By promoting a patient-centric and technologically advanced approach, this paper contributes to the evolving field ofBPMin chronic disease management, underscoring the critical role of telemedicine and BPM in transforming healthcare delivery and improving patient outcomes.
