What Happened? A Closer Look at the SELECT Trial
A major clinical trial, the SELECT trial, has revealed a potential increased risk of serious cardiovascular events – including heart attack, stroke, and cardiovascular death – in individuals with obesity and established cardiovascular disease who were treated with semaglutide (Ozempic) compared to those receiving a placebo. The study, involving over 17,600 participants, initially aimed to determine if semaglutide could reduce the risk of these events, but the results showed the opposite effect in a specific subset of patients.
Specifically, the trial observed a 24% increased risk of cardiovascular events in the semaglutide group. While the primary outcome didn’t reach statistical significance across the entire study population, a closer examination revealed a statistically meaningful increase in risk among patients with a prior heart attack.
Who is Affected and Why Does This Matter?
This finding is notably significant for the estimated 16.7 million Americans with heart disease and obesity. Ozempic and similar drugs (like Wegovy, which contains the same active ingredient, semaglutide, but at a higher dose) have become incredibly popular for weight loss, and are often prescribed *despite* existing cardiovascular conditions. The SELECT trial highlights the need for careful patient selection and monitoring.
the increased risk appears to be concentrated in individuals with pre-existing cardiovascular disease,especially those who have previously experienced a heart attack.This suggests that semaglutide may not be appropriate for all patients with obesity, and a thorough cardiovascular risk assessment is crucial before initiating treatment.
Understanding the Results: Potential Mechanisms
the reasons behind this increased risk are still being investigated.Several theories are being explored, including the possibility that rapid weight loss itself can sometimes destabilize existing cardiovascular conditions. Another hypothesis centers on the drug’s effects on blood pressure and heart rate, which could possibly exacerbate underlying heart problems. It’s also possible that the drug interacts with other medications commonly prescribed for cardiovascular disease.
Researchers are also considering whether the observed effect is specific to semaglutide or could extend to other GLP-1 receptor agonists, a class of drugs that includes medications like liraglutide (Saxenda) and dulaglutide (Trulicity). Further research is needed to determine the broader implications for this drug class.

What Does This Mean for Patients? FAQs
I’m taking Ozempic for weight loss. Should I stop?
Do not stop taking any medication without first consulting your doctor. If you have existing cardiovascular disease, schedule an appointment to discuss these findings and whether Ozempic remains appropriate for you. Your doctor will assess your individual risk factors and make a recommendation based on your specific situation.
Are other weight loss drugs affected?
this finding specifically relates to semaglutide (Ozempic/Wegovy). While other GLP-1 receptor agonists share a similar mechanism of action, more research is needed to determine if they carry the same risk.Discuss your concerns with your physician.
What about peopel without heart disease?
The increased risk was most pronounced in individuals with pre-existing cardiovascular disease. However,it’s vital to remember that even those without a known heart condition should be monitored for potential cardiovascular effects while taking semaglutide.
