Covid Vaccine and sudden heart attacks: Delhi AIIMS says no connection
However, a glimmer of hope appeared with the Covid vaccine, which, even though did not give complete immunity against the virus, made the ailment much less severe.
Of late, there have been talks about the vaccine's long term effects on health, in particular cardiac health, as more and more young Indians are dying of "sudden" heart attacks. However, recently, doctors and researchers at Delhi's All India Institute of Medical Sciences (AIIMS) have addressed these concerns.
Their studies show there is no clear link between Covid vaccines and sudden cardiac arrest deaths in India.
What started the worry
After the Covid-19 vaccination, and even till now, some cases of young people dying suddenly from heart attacks or cardiac arrest were reported. These incidents led to fear and speculation that the vaccine might be causing these deaths. Social media posts and public figures added to the confusion, making many people anxious about vaccine safety, which was being seen as a precursor to cardiac events.

What Did AIIMS Delhi Study
AIIMS Delhi, in collaboration with the Indian Council of Medical Research (ICMR), launched a detailed study to find out if there was any connection between Covid vaccines and sudden cardiac deaths. The study focused on adults aged 18 to 45, a group where some of these sudden deaths were reported.
How was the study carried out
Researchers examined over 300 cases of sudden, unexplained deaths.
Post-mortems were conducted to find the real cause of death.
The study included people who had received one or more doses of the Covid vaccine.
What Did the Results Show
The main finding was on these lines: there is no evidence that Covid vaccines increase the risk of sudden cardiac arrest or heart attack deaths.
Most of the sudden deaths were linked to coronary artery disease (CHD), which is often caused by poor lifestyle choices such as unhealthy diet, lack of exercise, smoking, and stress.
Some deaths were due to genetic factors or pre-existing health conditions.
The pattern of sudden deaths after vaccination was similar to what was seen before the pandemic.
What Do the Experts Say
Doctors at AIIMS Delhi have strongly stated that the benefits of Covid vaccines far outweigh any risks. Dr. Sanjay Rai, Professor of Community Medicine at AIIMS, explained that while every vaccine or medicine carries some risk, the overall benefit of vaccination in saving lives during the pandemic was huge.
Dr. Karan Madan, Associate Professor at AIIMS, said, 'Covid vaccines were effective and played a crucial role in reducing mortality. A study was done on sudden cardiac deaths to review the vaccines used so far, but no clear association was found with sudden cardiac deaths'.
Dr. Randeep Guleria, former Director of AIIMS, also pointed out that heart attacks in young people is more likely due to lifestyle, genetics, and other health issues, not the vaccine.
What About Other Studies
The findings from AIIMS Delhi are supported by other major studies in India:
The ICMR's National Institute of Epidemiology conducted a large study across 47 hospitals in 19 states. It found no link between Covid vaccination and sudden unexplained deaths among adults.
The Union Health Ministry and the Serum Institute of India (maker of Covishield) have also confirmed that the vaccines are safe and scientifically validated.
Why do sudden cardiac arrests happen
Sudden cardiac arrest can occur for many reasons, including
Coronary artery disease (blocked arteries)
Genetic factors (family history of heart disease)
Unhealthy lifestyle (poor diet, lack of exercise, smoking, alcohol which over years weaknes the heart)
Pre-existing health conditions (diabetes, high blood pressure)
Stress and obesity
What should one do:
Regardless of this breather, one should take care of your heart health. For this
Exercise often
Consume heart healthy foods
Keep your BP under check
Quit smoking/reduce alcohol
Ditch the junk
Lose weight, if you are overweight
Get yourself tested every year

Ministers tried to downplay incident, say oppn leaders
Kottayam: Congress intensified its protest against govt over the building collapse at Kottayam medical college hospital wherein a 52-year-old woman was killed. The irresponsible behaviour of ministers led to D Bindu's death, said opposition leader V D Satheesan at Thalayolaparambu on Friday. Satheesan said the ministers' remarks that the building was closed and no one was inside hindered the rescue operation. "Normally, if a hospital building collapses, govt should provide adequate compensation. But in this case, since the rescue operation was hampered by the ministers, govt has more responsibility," he said. He demanded that govt provide compensation of not less than Rs 25 lakh to the family of Bindu, who was killed in the building collapse, and to undertake her daughter's treatment and offer a job to a family member. Satheeshan said health minister Veena George was incapable of continuing in the position as medical colleges and other hospitals in govt sector were facing shortages of medicines and other materials for treatments. KPCC president Sunny Joseph, who visited the MCH and Bindu's house on Friday, termed her death as a "murder" alleging attempts by ministers George and V N Vasavan to downplay the incident. He said the ministers' eagerness to justify themselves following the incident resulted in the loss of life. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like '이것' 부족하면 운동 소용없다.. 갱년기 살찐 진짜 이유 워킹맘 로즈 더 알아보기 Undo He added that Congress would strengthen its protest to save the health sector. "The first phase was protests in front of medical colleges. The second phase of protests will be held in front of taluk district hospitals on July 8," Joseph said. Meanwhile, Puthuppally MLA Oommen on Friday announced a financial aid of Rs 5 lakh to Bindu's family from Oommen Chandy Foundation. Oommen had reached the spot soon after the incident on Thursday. IUML national general secretary P K Kunhalikutty said George should take moral responsibility for Bindu's death, accusing the minister of having handled the situation irresponsibly. In Malappuram, Kunhalikutty said, "It is not the minister's job to simply echo what officials say. Her response was extremely irresponsible. That is why UDF has demanded her resignation on moral grounds." Muslim Youth League activists took out a march from Vadakke Bus Stand area to the DMO office in Thrissur. Police erected barricades but the protesters tried to push the barricades and proceed to the DMO office, led to tense moments. Police then used water cannons to disperse the protesters.

Yes to dope tests, no to drugs: Panjab University pupils must sign pledge
Representative image CHANDIGARH: Panjab University students have to give an undertaking at the time of admission to stay away from drugs and submit to medical tests at random. This mandatory declaration binds students and their parents to acknowledge university's zero-tolerance policy on drugs, alcohol and tobacco - both in hostels and on campus. According to new rules, students must consent to undergo random drug testing - including breath, blood or urine analysis - if deemed necessary by Panjab University (PU) authorities. The move is in line with a University Grants Commission advisory, calling on all higher educational institutions to implement anti-drug measures. It recommended obtaining written commitments from students, creating awareness, and strengthening surveillance systems to prevent substance abuse. The university's new undertaking warns of strict disciplinary action, including suspension, expulsion or legal proceedings against students found in possession of or involved in consumption or distribution of banned substances. PU authorities have also introduced compulsory guest registration in hostels and are in the process of tightening access control. Officials said the anti-drug undertaking was part of a broader crackdown to safeguard campus environment and student wellbeing. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like CEO da Apple Impressionado: O Melhor App Para Intelectuais do Mundo Todo Blinkist Undo "This isn't just about one incident. The undertaking, awareness drives and improved monitoring are part of a systematic effort to make PU a safe and drug-free campus," said a senior official. PU has instructed all departments and hostel wardens to collect signed undertakings from students and their parents before finalizing admissions. The move comes after the death of an outsider of a suspected drug overdose in a PU boys' hostel in Nov. The case triggered scrutiny, especially after a student and a former student were arrested.
