Heart disease is the number one cause of death in the United States.
Even though there are many treatments available, it is still a serious problem for millions of people.
Doctors have spent years trying to stop it by treating high blood pressure, high cholesterol, and giving patients medicines like aspirin and statins. These treatments help, but the disease still causes many deaths and health issues. It’s like trying to stop a wildfire with just a few buckets of water—sometimes it’s just not enough.
Now, scientists at the University of Michigan may have found something new that could change the way we fight heart disease. They have discovered a protein in the body called suPAR, which stands for soluble urokinase plasminogen activator receptor.
This protein plays a role in how our immune system works. It helps the body react to infections and injury. But when there’s too much of this protein in the body, it can lead to serious health problems.
One of the biggest problems is something called atherosclerosis. This is when the blood vessels become hard and narrow, making it harder for blood to flow. That can lead to heart disease and heart attacks.
The researchers found that people with higher levels of suPAR in their blood were more likely to get heart disease, even if they didn’t have other risk factors like high cholesterol or smoking.
They also discovered that some people are born with genes that make their bodies produce more suPAR. In large studies involving thousands of people, those with this gene had a higher risk of developing heart disease.
To confirm their findings, the scientists did experiments on mice. Mice that had high levels of suPAR also developed more serious signs of atherosclerosis.
But the discovery doesn’t stop there. The researchers also found a strong link between suPAR and kidney disease. Many Americans have kidney problems, and people with kidney disease often have heart disease too.
It turns out that high suPAR levels may be one reason why both these diseases happen together. This suggests that the heart and kidneys are more connected than we thought. If we understand how suPAR works, we might be able to treat both heart and kidney diseases at the same time.
This research was led by Dr. Salim Hayek and his team. They believe that studying suPAR might open the door to new treatments that go beyond just lowering blood pressure or cholesterol. If scientists can find a way to lower suPAR levels or block its harmful effects, it might prevent heart disease in a whole new way.
Although this discovery is still in the early stages, it offers real hope. It reminds us that there is still so much we don’t know about how our bodies work—and how diseases develop. But with each new finding like this one, we get closer to better treatments and, hopefully, a future where heart disease is no longer the biggest killer.
