Bengaluru, June 30, 2025 – A sudden spike in heart attack-related deaths in Karnataka’s Hassan district has sparked public concern and speculation over a possible link with COVID-19 vaccines. As 23 young and middle-aged individuals succumbed to cardiac arrest within just 40 days, Chief Minister Siddaramaiah ordered an investigation, raising queries about a potential connection to vaccination.
ICMR and AIIMS Confirm No Link with COVID-19 Vaccines
Responding to growing alarm, the Ministry of Health and Family Welfare issued a statement dismissing any correlation between COVID-19 vaccination and sudden cardiac deaths.
“Extensive studies by ICMR and AIIMS on sudden adult deaths post-COVID vaccination have conclusively found no evidence of a vaccine link,” the ministry said.
The Indian Council of Medical Research (ICMR) and National Centre for Disease Control (NCDC) backed the claim, noting that India’s vaccines are safe and effective, with severe side effects being extremely rare.

Profile of the Deceased: Mostly Young or Middle-Aged
The death pattern raised red flags due to the age group of the deceased. Most victims were between their 20s and 50s, reportedly with no known chronic conditions. This unusual demographic has fueled public anxiety and misinformation across social media platforms.
What Do Medical Experts Say?
Cardiologists emphasized that COVID-19 vaccines are not a risk factor for heart attacks, citing both national and global studies.
“An analysis of 250 sudden cardiac deaths across India clearly ruled out vaccine-induced triggers. In fact, COVID-19 infection poses a significantly higher heart risk, with myocarditis cases 5–15 times more common post-infection than post-vaccination,” said Dr. Basavaraj Utagi, Senior Consultant Cardiologist at Fortis Hospital, Cunningham Road.
Lifestyle and Urbanisation: The Silent Culprits
Experts are pointing toward lifestyle-related and environmental causes for the surge in cardiac deaths.
“Factors such as high stress levels, poor diet, lack of physical activity, smoking, and pollution are more likely contributors,” explained Dr. Rahul Gupta, Director of Cardiology at Gleneagles Hospital, Mumbai.
Rapid urbanisation, access to processed foods, increasing obesity, and sedentary routines have created a perfect storm for heart-related illnesses, particularly among the younger population.
Atherosclerosis: A Hidden Danger
One key medical explanation is atherosclerosis—a condition where plaque builds up in the arteries, narrowing them and reducing blood flow to the heart. This often remains undiagnosed in young adults until it results in fatal consequences.
“Even individuals who appear outwardly healthy may have undetected heart conditions. Regular health screenings are essential,” Dr. Gupta emphasized.

Vaccination Still Crucial, Say Doctors
While speculation continues, experts unanimously urge the public to trust science and public health data.
“Vaccines remain a critical defense against COVID-19 and its complications. Misattributing unrelated health issues to vaccines undermines public trust,” said Dr. Utagi.
Instead, public health efforts must focus on increasing awareness about cardiac health, improving screening, and promoting healthier lifestyles, especially in high-risk districts.
