Introduction

On May 15, 2025, the Japan Society of Cardiovascular Intervention and Therapy (CVIT) will publicly launch a groundbreaking system known as the "Heart Map." This tool is designed to streamline the search for facilities capable of providing catheter-based treatment for acute myocardial infarction (AMI). Given the increasing rates of AMI cases, particularly those categorized as ST-elevation myocardial infarction (STEMI), timely access to treatment has never been more critical. This initiative is part of a broader strategy to ensure that patients can receive rapid and effective medical intervention during emergencies.

Overview of Current Challenges

Recent studies indicate a troubling rise in the number of AMI cases, especially severe STEMI presentations, which increased by approximately 2,250 cases between 2019 and 2023. Despite Japan's overall population decline, the aging demographic suggests that the number of AMI patients will continue to grow. Alarmingly, the mortality rate post-catheter treatment reached 6.5% in 2023, the highest recorded in the last five years. Prolonged time from hospital arrival to blood flow restoration has shown to substantially increase mortality rates, emphasizing the need for rapid treatment and intervention.

The Medical Workforce Crisis

The burden on medical professionals responding to these emergencies has intensified, with 44% of healthcare facilities expressing concerns about sustaining emergency care capabilities. Currently, only 8% of hospitals provide adequate on-site medical staff for acute cardiology emergencies, leading to a reliance on doctors who must remain available at home for urgent calls. Many physicians report inadequate rest after handling emergencies, contributing to a physically and mentally taxing work environment. Surveys reveal over 90% of doctors feel they lack sufficient time off, heightening concerns about both their well-being and the quality of patient care.

Younger and older physicians are increasingly taking on more responsibilities, while a notable decline in the number of mid-career specialists poses a serious challenge. The concentration of younger doctors in urban hospitals exacerbates resource shortages in rural areas, risking the stability and accessibility of acute care. As a result, ensuring a supportive framework for healthcare professionals is paramount, both for the sustainability of services and for patient safety.

Japan's Medical Landscape

Japan stands out as a leader in acute AMI survival rates due in part to an extensive network of hospitals equipped for emergency catheter treatments. This hardly occurred by chance; it is the result of a concerted effort by medical professionals to streamline care. The goal is to achieve blood flow restoration within 90 minutes after a patient's arrival at the hospital, which dramatically enhances survival rates. With legislative changes that enforce stricter work-hour regulations, the fear is that hospital policies may inadvertently undermine this life-saving structure. The CRIT working group's surveys reflect a clear discrepancy in medical services across geographical areas, highlighting the dangers posed by rural medical facilities lacking appropriate resources.

The Proposal for Systematic Reformation

In response to the observed disparities and the impending crisis in cardiovascular emergency care, the CVIT has urged the establishment of strategic initiatives aimed at attracting new healthcare professionals to the field. Solutions such as financial incentives, workload redistribution, and creating a supportive environment for young doctors are essential. There’s a pressing need for an integrated approach to bolster cardiovascular care through targeted training programs focused on nurturing skills required for complex procedures.

Conclusion

The launch of the Heart Map system is a step toward tackling the formidable challenges posed by increasing rates of myocardial infarction in Japan. It is designed to provide essential pre-hospital information, enhancing the chances of survival by encouraging patients to access care sooner. By fostering community engagement and supporting healthcare professionals, the future of cardiovascular emergency medical services in Japan can be assured. The responsibility of maintaining and improving these systems falls not just on medical institutions but on the collective effort of society as a whole, ensuring that every citizen's health is prioritized and protected.
