COVID-19 links to spike in sudden death risks among young adults says an Indian study

A recent study conducted by the Indian Council of Medical Research (ICMR) has provided vital insights into the factors associated with sudden deaths among young adults aged 18-45 in India. 

The study by ICMR looked into factors associated with sudden deaths among adults aged 18–45 in India, reveals the intricate web of risks connected to severe COVID-19, lifestyle habits, and COVID-19 vaccination. One of the oldest medical research organisations in the world is the Indian Council of Medical Research (ICMR), New Delhi, which serves as the supreme authority in India for the planning, directing, and advancement of biomedical research.

The investigation, which concluded this October, involved a multi-centric matched case-control study. One of the most alarming revelations is the potential link between COVID-19 infections and sudden deaths due to heart attacks.

It is also worth noting that the study found COVID-19 vaccination did not increase the risk of sudden death among young adults.

Conduct of the study

The study examined the causes of these unexplained fatalities and included cases of healthy people in India between October 1, 2021, and March 31, 2023, who suddenly passed away from unknown causes. The participants in the study were between the ages of 18 and 45 and had no underlying medical conditions.

The results demonstrated that immunisation had no bearing on the nation’s young people’ higher risk of unexpected deaths. Conversely, the study summary indicates that the immunisation decreased the adult population’s risk of unexpected deaths.

Four matched controls, one for each case based on location, gender, and age, were used. In this study, 729 cases and 2,916 controls were enrolled. Data were gathered from the cases and controls regarding their medical history, lifestyle choices such as smoking, drinking, and engaging in intense physical activity, hospitalisation due to COVID-19, and vaccination history.

The research delved into several factors contributing to sudden deaths, including a family history of sudden deaths, prior hospitalization for COVID-19, and lifestyle habits such as binge drinking and intense physical activity shortly before death. These risk factors highlight the need for a comprehensive understanding of sudden deaths among young adults and the urgency of addressing them.


According to the study by ICMR, Covid-19 infections may result in heart attacks that cause unexpected deaths. It further specifies that overexertion should be avoided for at least a year or two by individuals who have experienced a severe episode of the virus.

The study’s results gain particular significance in light of recent events during the Navratri celebrations in Gujarat, where a series of heart attacks resulted in multiple fatalities. This unfortunate incident underscored the importance of recognizing and addressing the risks associated with sudden deaths, especially in the context of COVID-19.

Union Minister Mansukh Mandaviya stressed the significance of the study’s findings, emphasizing that individuals who have experienced a severe bout of COVID-19 should refrain from strenuous physical activity for a period of one to two years. This advice is critical in minimizing the risk of heart attacks and cardiac arrests, and it highlights the essential role of healthcare professionals and authorities in educating the public about the potential risks associated with COVID-19 and its aftermath.

Furthermore, the study also examined the potential link between COVID-19 vaccination and sudden deaths due to heart attacks. Importantly, it revealed that COVID-19 vaccination did not contribute to an increased risk of sudden deaths among young adults in India.

This information should help allay concerns surrounding the safety of vaccination, thus encouraging more individuals to get vaccinated and play their part in protecting themselves and their communities.

Multiple reasearch results

A study conducted in Italy looks at the risk of heart attack after recovering from COVID-19. According to the study, patients who recovered from COVID-19 had a 93% higher risk of acute myocardial infarction than people in the general population.

One of the major studies assessing the long-term cardiovascular consequences of COVID-19 suggests that even individuals with mild disease may be more susceptible to heart issues a year after infection. Nature Medicine published the study in February.

Those with mild Covid had a 39% increased risk of heart problems in comparison to the modern control group, or 28 more cardiovascular problems per 1000 people in a 12-month period, according to the researchers’ detailed analysis of this population.


In summary, the ICMR study provides a deep dive into the intricate factors associated with sudden deaths among young adults in India.

COVID-19 and certain lifestyle habits pose credible risks, the study reaffirms that COVID-19 vaccination is safe and effective in reducing the likelihood of sudden deaths.

This research underscores the importance of public health measures, individual awareness, and informed decision-making to safeguard against the potential risks of COVID-19 and its consequences.
