Study Reveals 71% Increased Risk of Cardiovascular Events in Obstructive Sleep Apnea Patients
Synopsis
A new study indicates that individuals with obstructive sleep apnea face a staggering 71% greater risk of cardiovascular events and all-cause mortality, highlighting the urgent need for improved obesity management and early diagnosis.
Key Takeaways
71% increased risk of cardiovascular events in OSA patients.
Collaboration between Imperial College and Eli Lilly .
Significant obesity prevalence among OSA sufferers.
Importance of early screening and effective management of obesity.
Largest study of its kind conducted outside the US.
New Delhi, April 3 (NationPress) A recent study has revealed that individuals suffering from obstructive sleep apnea (OSA) face a 71% increased risk of experiencing cardiovascular events (CVEs) or dying from any cause compared to those without the condition.
This groundbreaking research, which will be showcased at the European Congress on Obesity (ECO 2026) in Istanbul, Turkey, from May 12-15, is a joint effort involving Imperial College Health Partners, Imperial College Healthcare NHS Trust in London, and Eli Lilly and Company.
According to Heather Fitzke, a co-author of the study from Imperial College Health Partners, “In adults, obstructive sleep apnea is associated with a higher likelihood of cardiovascular events or all-cause mortality, particularly in those who are obese, even after adjusting for various factors.”
OSA is characterized by repeated upper airway obstructions during sleep, leading to poor sleep quality and heightened cardiovascular risk.
The rate of obesity and being overweight among individuals with OSA ranges from 40% to 70%, with those who are obese experiencing more severe forms of OSA than those without obesity.
This study aimed primarily to investigate the elevated risk of combined CVEs or mortality among adults diagnosed with OSA when compared to those without the diagnosis.
Using electronic health records from 2.9 million residents, researchers matched 20,300 individuals with OSA against 97,412 controls. Notably, 57.2% (11,613) of participants with OSA were also classified as obese, compared to 56.7% (55,264) of the matched controls.
The analysis revealed that the risk of CVEs or all-cause mortality was 71% higher in individuals with OSA compared to those without the disorder.
These findings emphasize the critical need for effective management of obesity and stress the importance of early screening and diagnosis. According to Fitzke, this represents the largest matched case-control study of obstructive sleep apnea conducted outside the US to date.
Point of View
Revealing a concerning link between obstructive sleep apnea and increased cardiovascular risks. The emphasis on obesity management and early detection is crucial for public health, making this research particularly relevant in today's context.

Frequently Asked Questions
What is obstructive sleep apnea?
Obstructive sleep apnea (OSA) is a sleep disorder characterized by repeated interruptions in breathing during sleep due to airway obstruction.
How does OSA affect cardiovascular health?
OSA increases the risk of cardiovascular events and all-cause mortality by causing repeated drops in blood oxygen levels, leading to increased strain on the heart.
What percentage of OSA patients are also obese?
The prevalence of obesity among individuals with OSA ranges between 40% to 70%.
What was the aim of the recent study on OSA?
The study aimed to assess the increased risk of cardiovascular events and mortality in adults diagnosed with OSA compared to those without the condition.
Where will the study be presented?
The study will be presented at the European Congress on Obesity (ECO 2026) in Istanbul, Turkey, from May 12-15.
