While working a night shift at a hospital in London, Dr. Abhijit Ray studied an electrocardiogram (ECG) printout, considering how to improve cardiac diagnostics in areas with limited resources. His patient, a middle-aged man with no significant medical history, showed subtle signs of heart failure that standard tests had missed. This experience led Dr. Ray to develop a solution that would help detect heart problems earlier.
He created a patented formula that measures Left Ventricular Ejection Fraction (LVEF) directly from ECG readings. This development could help medical professionals identify heart failure symptoms earlier, potentially reducing deaths.
“In India and across the world, we are seeing more cases of undetected heart failure,” Dr. Ray says. “When we find it using current methods, patients have often progressed too far. We needed a better way to find these cases early.”
Making Cardiac Testing More Available
Heart failure affects about 64 million people worldwide, yet doctors often diagnose it late. Traditional detection requires echocardiograms, which many healthcare facilities cannot access. Dr. Ray’s formula, protected by USPTO patent 11517204B2, uses basic ECG tests to estimate LVEF, making detection possible in small clinics.
This work fits well with India’s growing medical technology sector, where artificial intelligence (AI) improves patient care. Experts predict the Indian healthcare market will double within five to seven years as more companies invest in AI medical solutions.
Dr. Ray led efforts to establish Impending Heart Failure as a medical category, which the World Health Organization might add to its ICD-11 classification. He also developed an AI system to evaluate Dengue Shock Syndrome risk, showing how technology can prevent serious illness.
“We can now predict many dangerous conditions,” Dr. Ray says. “Our main task is getting these improvements into daily medical practice.”
One Nation, One ECG: Taking Action
Dr. Ray started the One Nation, One ECG program to help more people access heart failure screening. His team distributes handheld ECG devices throughout India, focusing on areas that lack specialized cardiac care. The program has screened more than 3,500 patients.
“Medical advances only matter if people can use them,” Dr. Ray says. “New diagnostic tools must reach beyond major hospitals.”
The program has attracted attention from government officials, healthcare policy experts, and international health organizations. While Dr. Ray helps lead the effort, One Nation, One ECG succeeds through teamwork among doctors, community health workers, and public health supporters.
Recognition for Medical Progress
Dr. Ray received a 2025 Global Recognition Award for his work in cardiology and medical innovation. This honor acknowledges his efforts to improve cardiovascular testing and increase access to medical technology worldwide.
The award places him among respected global healthcare leaders and shows how Indian medical research benefits patients everywhere.
Next Steps in Heart Health
Dr. Ray continues working to detect heart problems early using AI diagnostics and community health programs. More patients will benefit from these advances as his team expands One Nation and One ECG and promotes ECG-based LVEF measurement.
“I focus on saving lives,” he says. “That motivates all our work.”
As heart disease becomes more common worldwide, Dr. Ray shows that basic ECG tests might help solve this growing problem. His work demonstrates how medical science can serve more patients effectively.
