Japan Myocardial Infarction Market to Grow Amid Aging Population and Cardiovascular Awareness

Japan Myocardial Infarction (MI) Market Overview

According to Renub Research Recent Report Japan Myocardial Infarction (MI) Market is projected to experience steady growth over the forecast period 2025–2033. Valued at US$ 153.44 million in 2024, the market is expected to reach US$ 198.65 million by 2033, expanding at a CAGR of 5.03%. The growth is largely fueled by Japan’s aging population, increasing prevalence of cardiovascular diseases, rising public awareness, and technological advancements in both diagnostics and treatment methods.

Understanding Myocardial Infarction

Myocardial infarction, commonly known as a heart attack, occurs when blood flow to a section of the heart is blocked, usually by a clot, causing damage to heart muscle tissue. Immediate medical intervention is critical to prevent serious complications, including heart failure, arrhythmias, or sudden cardiac death. Typical symptoms include chest pain, shortness of breath, weakness, and nausea.

MI is one of the leading causes of morbidity and mortality in Japan, especially among older adults. With over 28% of the population aged 65 or older, the country faces an increasing burden of cardiovascular conditions. Lifestyle factors such as high salt consumption, sedentary behavior, and rising obesity rates contribute to MI prevalence. While Japan’s healthcare infrastructure is advanced, geographical disparities in emergency services and cardiology expertise remain challenges. Consequently, Japan continues to invest in early detection, rehabilitation, and public education programs to reduce MI-related healthcare costs.

Key Drivers of Market Growth

Aging Population and Cardiovascular Risk

Japan has one of the world’s oldest populations, with nearly 30% aged 65 or above. Aging is a significant risk factor for MI due to associated conditions like hypertension, diabetes, and atherosclerosis. The growing elderly demographic is driving demand for diagnostic tools, treatment equipment, and long-term care solutions.

As of September 2024, Japan’s elderly population reached 36.25 million, representing roughly one-third of the nation. This demographic shift underpins the expansion of the MI healthcare sector, creating opportunities for innovative treatment and preventive interventions.

Advances in Diagnostic and Interventional Technologies

Japan is a global leader in medical technology, particularly in cardiology. High-resolution imaging, cardiac biomarkers, and minimally invasive interventions such as percutaneous coronary intervention (PCI) have significantly improved early detection and treatment outcomes.

Telemedicine solutions and AI-based diagnostic platforms are enhancing timely MI identification and follow-up care. For example, in June 2025, Terumo Corporation signed a distribution agreement with MedHub-AI to bring the “AutocathFFRTM” software to Japan, enabling rapid and precise cardiac assessments in hospitals nationwide.

Government Initiatives and Healthcare Infrastructure Expansion

The Japanese government actively promotes cardiovascular disease awareness and prevention through national programs and subsidized health schemes. The Japanese Circulation Society frequently revises MI treatment guidelines, while regional health authorities expand emergency response networks.

Investments in cardiac care units, particularly in rural and elderly-dense areas, improve access to timely intervention. Public and private initiatives collectively enhance early detection, treatment outcomes, and overall market growth. For instance, the MEDICAL JAPAN TOKYO 2024 exhibition highlighted emerging technologies and trends across medical devices, elderly care, and pharmacy sectors, emphasizing innovation in cardiovascular care.

Challenges in the Market

Delayed Patient Response and Low Emergency Awareness

Despite improved care, delays in seeking treatment remain a critical issue. Cultural norms emphasizing self-endurance and low public awareness of MI symptoms can result in late intervention, complicating treatment and reducing survival rates. Hospitals and clinics continue to invest in awareness campaigns to encourage prompt emergency care.

High Cost of Advanced Treatment

Although Japan has universal healthcare, advanced MI treatments—including drug-eluting stents, cardiac rehabilitation, and long-term medications—can be expensive. This poses challenges for rural or low-income populations. Comorbid conditions further increase hospitalization duration and follow-up care, limiting access and creating disparities in MI management.

Market Segments

Treatment

Japan’s MI treatment segment includes pharmaceuticals, angioplasty procedures, coronary artery bypass grafting (CABG), and post-MI rehabilitation services. Hospitals maintain state-of-the-art catheterization labs with experienced cardiologists for acute MI management.

Pharmaceutical interventions typically involve beta-blockers, statins, anticoagulants, and antiplatelet agents. Emerging treatments, including PCSK9 inhibitors and SGLT2 inhibitors, are gaining traction among high-risk or diabetic patients. Personalized treatment strategies are increasingly improving post-MI survival rates and patient quality of life.

Diagnostic Devices

Diagnostic tools are essential for MI detection, including ECGs, echocardiograms, CT coronary angiography, and troponin testing. AI-enabled platforms are now being used to interpret ECGs in real time and alert clinicians to abnormalities.

Telecardiology and mobile diagnostic units are expanding access in rural regions, reducing time-to-diagnosis and improving treatment outcomes in Japan’s aging population.

Pharmaceuticals

MI pharmacotherapy is a cornerstone of treatment. Drug classes include:

Antiplatelet agents (aspirin, clopidogrel)

Statins

ACE inhibitors and beta-blockers

Emerging therapies such as PCSK9 and SGLT2 inhibitors

Domestic and international pharmaceutical companies are investing heavily in cardioprotective agents, enhancing the MI pharma market.

Rehabilitation

Cardiac rehabilitation programs are increasingly recognized for reducing recurrence risk and improving post-MI outcomes. Programs typically combine supervised exercise, dietary guidance, and stress management.

Despite government support, participation remains limited due to mobility constraints and lack of rural rehab centers. Expanding access to rehab facilities is critical for long-term cardiovascular health in Japan.

Regional Insights

Tokyo

Tokyo, Japan’s capital, has the highest concentration of specialized cardiac care centers, including the National Cerebral and Cardiovascular Center. The city’s urban stress and lifestyle factors contribute to high MI risk, driving demand for emergency and preventive cardiac care. Tokyo is also a hub for R&D, clinical trials, and digital health innovations in MI management.

Aichi

Aichi Prefecture, home to Nagoya’s industrial workforce, faces sedentary lifestyles and high stress, increasing MI risk. Local hospitals have expanded catheterization labs and collaborate with tech firms to develop digital cardiac monitoring solutions, improving preventive and post-MI care.

Shizuoka
