No Link Between Covid Vaccine & Sudden Cardiac Deaths: Karnataka Govt Research Amid Hassan Surge
Amid the surge in heart attack fatalities in Hassan district, a research commissioned by the Karnataka government prior to the incident has found no causal link between Covid-19 vaccines and sudden cardiac deaths. The report has attributed the rise to an increase in conventional risk factors such as hypertension, obesity, and diabetes.
Speaking to CNN-News18, Dr KS Ravindranath, Director of the Sri Jayadeva Institute of Cardiovascular Sciences and Research, said, 'We haven't seen a direct link between vaccine or COVID and heart attacks."
'Risk factors have gone up post Covid'
Dr Ravindranath highlighted that their observational pilot study at Jayadeva Hospital, examining over 200 patients under 45 in April and May, did not find an association between premature cardiovascular disease and a prior history of COVID-19 infection or vaccination. But he highlighted that the risk factors had gone up significantly post COVID.
'Post-Covid, we have seen a 6-8% increase in other risk factors such as hypertension, obesity, diabetes, etc.," Dr Ravindranath noted, emphasising the shift in risk profiles. He further clarified that these increases are also observed in younger demographics (20-30 year olds), attributing it to stress, lifestyle changes, and potential hormonal shifts post-Covid, alongside job losses.
'Hassan incident in line with broader trend'
Regarding the ongoing probe into deaths in Hassan district, Dr Ravindranath clarified that it's not an isolated epidemic, but rather in line with broader trends. 'What we have seen is that most of the private hospitals there, if you look at most of the people admitted there due to heart attacks, 200 plus," he explained.
'Any heart attack has a 5-6% mortality rate, up to 8% sometimes, in that range, mortality is known. So when the numbers are more, obviously the deaths are severe."
He added that India's incidence of heart attacks has generally risen compared to Western countries, occurring about 10 years earlier on average.
The report's recommendations include establishing a cardiac surveillance program, a national registry for sudden cardiac deaths among young adults, routine heart screenings at the school level, and public health campaigns promoting healthy lifestyles to address the growing burden of cardiovascular diseases.
On Karnataka CM Siddaramaiah speaking on the possible link between the vaccine and heart attack, Dr Ravindranath said that a member of civic society had petitioned the CM. 'There is a belief among people and health professionals that they are linked. So to clear the doubts of the public, he had asked whether the vaccine could cause it. The expert committee did not find a link," he said.
'Need for post-mortem'
Dr Ravindranath stressed on the need for post-mortem for cases of heart failures, registry of sudden cardiac deaths of youngsters, health checks of high school children to discern heart-related issues.
On the Hassan case, he said, 'We have asked for details and sent a questionnaire to the local health officials to understand what happened there…Compared to Western countries, heart attacks take place in India 10 years younger. We have seen a 15 per cent increase in youngsters coming to Jayadeva to check on their heart function."

Karnataka government mandates autopsies in sudden, unexplained deaths among young individuals
The study, led by Dr KS Ravindranath, Director of the Sri Jayadeva Institute of Cardiovascular Sciences and Research, concluded that while there has been a 4–5 per cent increase in heart attack cases among those under 45, the causes are linked to lifestyle factors -- including obesity, smoking, diabetes, and sedentary habits -- and not to Covid-19 vaccines or the infection itself. The expert committee was constituted in February this year following public anxiety and speculation about rising cases of sudden cardiac deaths among healthy young individuals, especially in the post-COVID period. Chief Minister Siddaramaiah had ordered the study, seeking clarity on whether vaccines or long Covid were contributing factors. Addressing the media on Monday, Gundu Rao said, 'There has been an increase in heart attack cases post Covid -- about 4 to 5 percent -- but it is due to multiple lifestyle-related factors. The study has found no evidence to link these deaths with the vaccine or Covid infection.' 'To act on the findings, the state will roll out a series of preventive measures. Apart from mandatory autopsies, the government will initiate cardiac screening for school students from Class 10 onwards, annual health check-ups for all government employees, and recommend similar screenings in private offices, industries, and institutions. Lifestyle education modules will also be introduced in school curricula to promote awareness on physical activity, screen time, and healthy eating habits,' the minister said.
