No link between Covid vaccine and heart attacks, says expert panel after row between Siddaramaiah, Kiran Mazumdar-Shaw
READ | Kiran Mazumdar-Shaw hits back at Karnataka CM Siddaramaiah for hinting COVID vaccines are behind heart attacks in Hassan
The committee, led by Dr C N Ravindranath, Director of the Sri Jayadeva Institute of Cardiovascular Sciences and Research, found no connection between early-onset cardiovascular conditions and previous Covid-19 infection or vaccination. In fact, the study found evidence that vaccines may offer long-term protection against cardiac events.
Contrary to popular speculation, the real drivers behind the increase in cardiac incidents appear to be the continued prevalence of traditional risk factors, such as hypertension, diabetes, high cholesterol, smoking, and lifestyle-related issues, the report stated. The findings echo international research, the panel said, which has also failed to establish any causal link between Covid-19 vaccines and sudden cardiac deaths.

While a temporary spike in cardiovascular events is observed shortly after recovering from Covid-19 due to heightened inflammation, the report clarified this effect does not persist in the long term. The panel emphasized that the recent spike in cardiac fatalities cannot be pinned down to a single cause. Instead, the situation reflects a complex interaction of behavioural, genetic, and environmental contributors.
The committee has proposed a series of public health measures, including nationwide surveillance for sudden cardiac deaths, the creation of autopsy-based registries, and cardiovascular screening programs starting at school age.

The social media spat between Siddaramaiah and Kiran Mazumdar-Shaw: What really happened
CM Siddaramaiah in a social media post had raised questions and the possibility that COVID-19 vaccinations might have contributed to fatalities in Hassan. 'It cannot be denied that the hasty approval and distribution of the Covid vaccine to the public could also be a reason for these deaths, as several studies worldwide have recently indicated that COVID vaccines could be a cause for the increasing number of heart attacks,' he had posted.
Kiran Mazumdar-Shaw had strongly criticized the statements, replying, 'COVID-19 vaccines developed in India were approved under the Emergency Use Authorisation framework, following rigorous protocols aligned with global standards for safety and efficacy. To suggest that these vaccines were 'hastily' approved is factually incorrect and contributes to public misinformation."
This led to a back-and-forth, with Siddaramaiah saying that seeking clarity is not misinformation, and that it is an act of governance rooted in empathy.
Mazumdar-Shaw later agreed with the need for investigations into sudden deaths but reiterated that the regulatory process followed for vaccine approval met international standards. 'My response was that due process was followed as prescribed by WHO for safety and efficacy for Emergency Use Authorisation,' she wrote. 'Losing lives in a sudden manner is always tragic, and I am glad an investigation is being conducted in Hassan district,' she added.

Delhi govt to launch 4-tier mental health programme for children, workers and seniors
New Delhi: The Delhi government is set to launch a dedicated mental health programme focused on children, the working class and senior citizens, through a four-tier model offering teleconsultation, counselling, OPD care and a referral system. In a bid to tackle the rising cases of stress and anxiety across age groups, a comprehensive mental health programme under the AYUSH intervention will help people of all ages, Delhi Health Minister Pankaj Singh said He said that the initiative -- aimed at promoting holistic well-being -- will focus on three key population groups: children, the working class and senior citizens. The service will be anonymous, accessible and rooted in traditional systems of medicine including Ayurveda, Homoeopathy and Unani, he said, adding that this will be the first focused mental health initiative under Ayush and it will support people at every stage -- from a phone call to a consultation, and even hospital-level care if needed. Many people hesitate to speak about mental stress. Through this platform, they can reach out anonymously and seek help without fear or stigma, the minister said. The programme will operate through a four-level structure starting from telephonic consultations, moving to mental health counselling , followed by OPD services at Ayush hospitals and a final referral stage in case specialised psychiatric intervention is needed. The programme is especially significant at a time when stress is increasingly being reported among school children, with some showing early signs of aggression and anxiety. Also, working professionals are burdened with high-pressure targets and a lack of work-life balance. Women who juggle home and workplace responsibilities will also be covered within this group. The elderly, too, face isolation and other age-related mental health challenges. Under the plan, people can call a dedicated helpline and book a time slot to speak with a counsellor. If the counsellor feels that in-person help is required, the case will be referred to OPDs at Ayush hospitals. There are currently four such teaching hospitals in Delhi -- Karol Bagh, Defence Colony, Najafgarh and Nanak Pura. If further care is necessary, the final level will involve referral to allopathic or psychiatric facilities based on Standard Operating Procedures (SOPs). Functioning under the Delhi government's health framework, the AYUSH systems comprise Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homoeopathy. PTI

CM irresponsible in saying Covid vax caused heart issues: Joshi
Hubballi: The rising incidence of heart attacks across the state has become a significant health concern. Following this, an expert committee appointed by the state govt concluded in their report that there is no linkage between heart attacks and Covid vaccination. Union minister Pralhad Joshi criticised CM Siddaramaiah , questioning his response to these findings. In a press conference here on Sunday, Joshi criticised the CM's "irresponsible attribution of heart attacks to Covid vaccines without proper investigation". He demanded the CM apologise to the nation and the scientific community. Joshi strongly denounced the CM's actions of questioning vaccine efficacy without reviewing expert findings, thereby disrespecting vaccine researchers and scientists. He insisted Siddaramaiah should publicly apologise to the country's scientific community. Regarding Siddaramaiah's vaccination status at 74, Joshi queried whether he received domestic or foreign vaccines. He referenced the expert committee's report led by Dr KS. Ravindranath of Jayadeva Institute, which clearly stated that there was no connection between vaccines and cardiac events. Joshi questioned the CM's stance on the official state committee's findings, absolving the vaccine of side-effects. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Canada is looking for skilled immigrants from Jamaica!

He noted Congress's tendency to doubt domestic achievements while readily accepting foreign alternatives.
