Dr. Thanikachalam Sadagopan (S. Thanikachalam), Padma Shri
Cardiologist, Teacher & Pioneer of Preventive Cardiology
The middle-aged executive sat across the table, looking anxious after a routine check-up.
“Doctor, my reports show high blood pressure and cholesterol. Am I heading for a heart attack?”
Dr. Thanikachalam Sadagopan leaned forward with a calm smile. “Not if we act now. Heart disease is often preventable. Let us change the risk factors together—diet, exercise, medicines if needed—and protect your heart before any damage occurs.”
That emphasis on prevention has been the hallmark of his long and distinguished career.
Born on 13 December 1939 in Tamil Nadu, Thanikachalam Sadagopan graduated with an MBBS from Madras Medical College in 1962. He completed his MD in General Medicine in 1967 from the same institution and earned his DM in Cardiology from Christian Medical College, Vellore, in 1971. He later trained in advanced echocardiography techniques, including Doppler, colour Doppler and transoesophageal echocardiography, at Tufts University, Boston.
He began his teaching career as a tutor and rose steadily through the ranks at various medical colleges in Tamil Nadu, including Kilpauk, Chengalpattu and Madras Medical College. In 1994 he joined Sri Ramachandra Medical College & Research Institute (now Sri Ramachandra University) in Chennai as Professor of Cardiology and Director of the Cardiac Care Centre. He served as Dean of Faculties and later as Vice-Chancellor of the university (2002–2005). After stepping down from the vice-chancellorship he continued as Chairman and Director of the Cardiac Care Centre and Professor Emeritus in Cardiology. He has also been an adjunct professor in the Biomedical Engineering Group at the Indian Institute of Technology, Madras.
Dr. Thanikachalam is widely recognised for his work in preventive cardiology. He has published extensively on cardiovascular risk factors, hypertension and vascular stiffness, particularly in South Asian populations. He participated in major multinational studies, including the PURSE-HIS Epidemiological Study in collaboration with Tufts University School of Medicine. He has also contributed to research on traditional Siddha medicines.
A dedicated teacher, he received the prestigious Dr. B.C. Roy National Award for the Best Medical Teacher from the President of India in 2003. In 2009 the Government of India conferred the Padma Shri on him for his contributions to medicine. He has also received Lifetime Achievement Awards from the Tamil Nadu Dr. M.G.R. Medical University and several other professional honours.
Even after decades in the field, he continues to stress the importance of lifestyle in protecting the heart.
“Most heart disease is not sudden,” he often tells students and patients. “It builds quietly over years. Our greatest opportunity is to intercept it early—through knowledge, discipline and care.”
From the classrooms and wards of Sri Ramachandra University to research collaborations and public-awareness efforts, Dr. Thanikachalam Sadagopan has spent a lifetime teaching that the best treatment for the heart is prevention, guided by science and compassion.
