What Does the Evidence Say About Wegovy and Heart Health?
The cardiovascular evidence for semaglutide comes primarily from the SELECT trial, a large, long-running study in adults with established cardiovascular disease and overweight or obesity. Participants taking semaglutide showed a statistically significant reduction in the risk of major adverse cardiovascular events — including heart attack and stroke — compared with those taking a placebo. This was notable because the benefit appeared to extend beyond what would be expected from weight loss alone.
How might semaglutide support heart health?
Researchers believe several mechanisms may be involved. As a GLP-1 receptor agonist, semaglutide acts on appetite-regulating pathways, leading to reduced calorie intake and body weight — both of which are established cardiovascular risk factors. There is also evidence suggesting direct effects on inflammation and blood pressure, though the full picture is still being studied. According to information held in the electronic Medicines Compendium, Wegovy's prescribing information references the cardiovascular outcome data as part of its licensed indication in eligible adults.
Who is this relevant for?
The cardiovascular findings are most relevant to people who already have established heart disease and meet the prescribing criteria for Wegovy. Whether the heart-health data applies to your own situation depends entirely on your medical history — something only your prescriber or doctor can assess. Wegovy is a prescription-only medicine, and suitability is always an individual clinical decision.
If you are also taking Mounjaro (tirzepatide) or curious how it compares, our overview of potential health benefits associated with Mounjaro covers what the evidence shows for that medicine. You can also explore our general Wegovy information hub for a broader look at how semaglutide works. Some people on GLP-1 medicines notice changes in heart rhythm; if that is something you have experienced, our page on heart palpitations and GLP-1 medicines covers what is commonly reported and when to seek advice.

Tracking Your Cardiovascular Wellbeing with GLP Trackr
If heart health is part of why you have been prescribed Wegovy, keeping a clear, consistent record of how you feel day to day can be genuinely useful — both for your own awareness and for conversations with your prescriber.
GLP Trackr's daily check-in lets you log mood, energy levels, and how you are feeling each morning in around 30 seconds. Over time, this builds a personal picture of your wellbeing trends that is far more useful to bring to an appointment than trying to recall how you felt three weeks ago. The app's insights and analytics help surface patterns — for example, whether your energy or sleep has shifted since starting or adjusting your medication.
When your prescriber wants a summary of your journey so far, the doctor report feature compiles your logged data into a clear, shareable overview — so nothing important gets left out of the conversation.
GLP Trackr supports people on both Wegovy and Mounjaro; you can read more about the broader GLP-1 journey in our GLP-1 medicines guide.
Important: GLP Trackr is a tracking and journaling app — it does not provide medical advice, and nothing in the app or on this page replaces the guidance of your prescriber or doctor. If you have any concerns about your heart health, cardiovascular symptoms, or how your medication is affecting you, contact your healthcare professional promptly. Any questions about your dose, suitability, or treatment plan should always be discussed with your prescriber.

The Most Advanced GLP-1 Brain Ever Built.
The first AI built exclusively for GLP-1 weight loss. Every insight, every meal plan, every prediction trained on one thing only: helping you get the most out of your medication.
Knows Your Cycle
GLPIQ tracks where you are in your injection cycle and adjusts everything around it: lighter meals on nausea days, higher protein when appetite returns, and smarter targets as your medication level shifts.
Predicts Before You Feel It
GLPIQ learns your personal side effect patterns over time. After a few cycles, it starts warning you the morning before a rough day — and adjusts your meal plan automatically.
Finds Your Golden Dose
GLPIQ analyses every dose you've been on: weight loss rate, side effects, food noise, mood, protein adherence and tells you which dose gave you the best results. No other app does this.

Frequently asked questions.
A large clinical trial called SELECT found that semaglutide (Wegovy) significantly reduced the risk of major cardiovascular events in adults with established cardiovascular disease and overweight or obesity. Your prescriber can advise whether this evidence is relevant to your individual situation.
Researchers believe the cardiovascular benefits of semaglutide may come from a combination of weight reduction, lower blood pressure, reduced inflammation, and possible direct effects of the GLP-1 receptor agonist mechanism. The full picture is still being studied.
The main cardiovascular trial focused on adults with existing heart disease. Whether the heart-health findings apply to you personally depends on your medical history and is a question for your prescriber or doctor — not something that can be generalised to everyone prescribed Wegovy.
Yes — always contact your healthcare professional promptly if you experience any cardiovascular symptoms, such as chest discomfort, palpitations, or shortness of breath. You can log how you feel in GLP Trackr to share with your prescriber, but the app does not replace clinical assessment.
GLP Trackr is a tracking app, not a medical device. It lets you log daily wellbeing, energy, mood, and side effects, and generate a summary report for your prescriber. It does not monitor or measure clinical cardiovascular markers.
