A landmark study has revealed a “silent” heart disease burden in rural India, proving that heart risks are no longer just an urban problem. The REACH Rural India Study, conducted by Kovai Medical Center and Hospital (KMCH) and published in The Lancet Regional Health – Southeast Asia, found that many seemingly healthy rural adults already show early signs of heart disease.

Key Findings: One in Four at Risk
The research team screened over 3,000 adults (aged 35–65) from rural areas around Coimbatore and Tirupur. Using a non-invasive scan called a CAC score to detect calcium deposits in the heart’s arteries, the study found that nearly one in four healthy rural adults have “silent” heart disease (subclinical atherosclerosis) and men are significantly more affected (33.5%) than women (18.5%). Over 83% of those with early signs of heart disease also had at least one risk factor, such as diabetes, high blood pressure, or cholesterol.

Traditionally, heart disease was thought to primarily affect city dwellers. However, principal investigator Dr. Thomas Alexander noted that rural populations are now facing similar risks due to changing lifestyles. “Heart disease risk is no longer confined to cities,” said Dr. Alexander. “We are seeing early arterial damage in rural communities even when there are no symptoms”.

The Opportunity for Prevention
The researchers emphasized that these findings should be seen as a “wake-up call” rather than a cause of panic. Lead scientist Dr. S. Mohanraj. commented that detecting heart disease at this early, silent stage allows individuals to act before a heart attack occurs. Dr. Mathew Cherian, chief radiologist, KMCH highlighted that identifying these risks early via imaging provides a vital window for lifestyle changes and medical guidance to prevent future health crises.

Congratulating the team on this landmark study, Dr. Nalla G Palaniswami, Chairman and Managing Director, KMCH, said: “Our mission has always been to bridge the gap between world-class healthcare and the underserved populations of rural India. The rising incidence of ‘silent’ heart disease in these regions is a wake-up call. We are committed to deploying advanced diagnostic tools and mobile health units to ensure that a person’s geography does not determine their life expectancy.”

Dr. Arun Palaniswami, Executive Director, KMCH, stressed on the importance of early intervention. ‘Early detection is our strongest weapon against heart disease. In rural areas, symptoms are often ignored or misdiagnosed until it is too late. We are working tirelessly to train local healthcare workers and implement screening programs that can identify high-risk individuals before a major cardiac event occurs.”

About the Study

This study, supported by the Indian Council of Medical Research (ICMR), is one of the largest of its kind in rural India. Core research group included Mr. Avinash Kumar, Dr. Thomas Alexander, Dr. S. Mohanraj, Dr. Mathew Cherian, Dr. Pudhiavan, Dr. Arulraj Ramakrishnan and Dr. Velmurugan. Dr. Nalla G. Palaniswami, Founding Trustee of KMCH Research Foundation, stated that such community-based research is essential for guiding future public health strategies and protecting the health of rural populations.
