A weekly injectable best known for weight loss has now been shown to cut heart attacks and strokes, even in people without diabetes. If you carry extra weight and heart risk, this is a conversation worth having with your doctor.
The finding comes from the SELECT trial, published in the New England Journal of Medicine in 2023. It randomized about 17,600 adults with established cardiovascular disease and overweight or obesity, none with diabetes, to semaglutide or a placebo.
Ask Your Doctor For This Heart Test♥️
There's a test that could tell you exactly what's happening inside your arteries right now.
Doctors used to order it routinely.
Not anymore.
It quietly disappeared from standard checkups.
Why?
Because what it reveals could change how millions of people think about heart health… and put billions in heart medication sales at risk.
You won't get this test at your next physical.
But you can still find out what it checks for and what to do about it.
P.S. If your last checkup came back "normal," that doesn't mean your heart is safe. This test checks something most panels completely miss.
Over roughly three years, the drug reduced major cardiovascular events, heart attack, stroke, and cardiovascular death, by about a fifth, alongside meaningful weight loss. It was the first trial to show a medication like this protects the heart in people without diabetes.
This reframes the drugs as more than cosmetic. The benefit appeared to go beyond the weight lost, which is why these medicines are now being studied for kidney disease, heart failure, and sleep apnea as well.
Keep both eyes open, though. These are prescription drugs with real downsides, common nausea and gut effects, meaningful cost and access problems, and a tendency for weight to return if you stop.
One caveat matters especially at your stage. Rapid weight loss strips muscle and bone along with fat, so anyone using these drugs should lean hard on protein and resistance training to protect the very tissue you are working to keep.
Note who was studied. SELECT enrolled higher-risk people with existing heart disease, so the proven cardiovascular benefit belongs to that group, and whether it extends to lower-risk women is a separate, open question.
So treat this as information, not a prescription. If you have excess weight and cardiovascular risk, ask your doctor whether the benefits and risks line up for you, and keep lifestyle as the foundation either way.
This is a genuine shift in what these medications can do, with real caveats attached. Bring it to your doctor as a question, not a verdict, and protect your muscle whatever you decide.
