Heart Disease reclaims Top Spot as Global Killer, Alongside Rising ‘Deaths of Despair’
A new report published Sunday in The Lancet medical journal reveals a concerning shift in global mortality, with heart disease and other chronic illnesses regaining prominence as leading causes of death, while deaths linked to COVID-19 have significantly declined. This resurgence of familiar health threats is unfolding alongside a troubling increase in “deaths of despair” – fatalities stemming from suicide,drug overdoses,and alcoholism – particularly among young adults in North america.
For Heather Evans of Calgary,the threat of heart disease is deeply personal.In 2004, at just 39 years old, she suffered two consecutive heart attacks. This was not an isolated incident; over the subsequent two decades, coronary artery disease claimed the lives of five of her seven siblings, one of whom died at the young age of 36. “There are always these empty chairs at the table,” Evans told CBC News, describing the enduring grief. “We look at each other and it’s just… profound sadness and a profound heartache that just never goes away.”
The latest data from 2023 confirms a global trend: heart disease, stroke, and chronic obstructive pulmonary disease (COPD) are now the top three causes of death worldwide. COVID-19, which surged to become the leading global killer in 2021, has fallen to 20th place just two years later. while deaths from infectious diseases like measles and tuberculosis have decreased, chronic, non-communicable conditions – including diabetes, Alzheimer’s disease, and drug use disorders – are on the rise.
Researchers warn that these “slow-burn” health threats often receive less attention than acute global crises, despite their massive impact on health and well-being. “It’s not as dramatic as an outbreak,” explained Michael Brauer, principal research sci
,” she added, highlighting the systemic barriers to care.
James MacKillop,a professor at McMaster University and the Peter Boris Chair in Addictions Research at St. Joseph’s healthcare Hamilton,agrees that Canada needs more youth-specific treatment programs and early intervention efforts involving specialized mental health professionals. He also noted that the causes of increased mortality among younger age groups are complex, ranging from feelings of alienation to the dangers of a toxic drug supply.
Recent data from the Public Health agency of Canada shows a 17% decrease in the Canada-wide opioid death rate in 2024 compared to the previous year, though numbers remain high. The Canadian Center on Substance Use and Addiction attributes this decline, in part, to changes in the drug supply and the tragic reality that many vulnerable users have already succumbed to overdose.
Canadian pediatricians are actively working to better understand the impact of substance use on children and teens. The Canadian Paediatric Surveillance Program, a joint initiative of the Public Health Agency of Canada and the Canadian Paediatric Society (CPS), recently launched a national study on life-threatening harms linked to illicit substances. Toxic drug overdose is now the leading cause of death for adolescents in British Columbia and a growing concern nationwide. The CPS stated that the three-year study will facilitate the co-development of overdose interventions with youth to reduce harm and improve health outcomes.
Despite the grim statistics, there is reason for hope. Experts emphasize that many of the factors contributing to global mortality are modifiable. Well-known risk factors for chronic health conditions – including smoking, alcohol consumption, diet, and physical activity – can be addressed through preventative measures.
Heather Evans, now 61 and experiencing heart failure herself, embodies this spirit of resilience. Despite her family history and her own health challenges, she is actively working to ward off the disease through exercise, a healthy diet, and quadruple bypass open-heart surgery in 2018. “It’s going to eventually take us,” Evans acknowledged, “But we’re not going to let it take our spirit.” She believes that increased awareness, a focus on healthy lifestyles, and reduced stress are crucial to preventing further losses. “Had I had the knowledge, I would have tried my best to eat a little bit better, and I would have exercised a heck of a lot more than I did when I was younger, you know?” she said. “There are so many components to what we can do that can absolutely give us the best chance in life not to get this disease.”
