Heart disease remains the leading cause of death around the world. Every year, millions of people die from heart attacks, strokes, and other cardiovascular problems.
Doctors and scientists have spent decades searching for better ways to prevent and treat these diseases because they continue to affect people of all ages and backgrounds.
One of the main causes of heart disease is a condition called atherosclerosis. This happens when fatty substances build up inside the arteries over time. These fatty deposits are known as plaques.
Arteries are blood vessels that carry oxygen-rich blood from the heart to the rest of the body. When plaques grow larger, they narrow the arteries and reduce blood flow.
This can create serious problems. If blood cannot flow properly to the heart, a person may develop chest pain or suffer a heart attack. If blood flow to the brain is blocked, it can cause a stroke. Sometimes plaques can suddenly break open, creating dangerous blood clots that block arteries completely.
A major reason plaques form is a condition called dyslipidemia. This means a person has unhealthy levels of fats in their blood, especially cholesterol and triglycerides.
Cholesterol is a waxy substance the body needs in small amounts, but too much “bad” cholesterol can stick to artery walls and form plaques. Triglycerides are another type of fat in the blood that can also raise the risk of heart disease when levels become too high.
Dyslipidemia is extremely common. Researchers estimate that almost half of adults may have unhealthy blood fat levels. Many people do not even know they have the condition because it often causes no symptoms in the early stages.
Doctors usually treat dyslipidemia with medicines such as statins and other cholesterol-lowering drugs. These treatments can lower harmful fats in the blood and help stabilize plaques so they are less likely to burst.
However, even with treatment, plaques often do not completely disappear. This is why researchers continue searching for new ways to reverse artery damage.
Now, scientists have made an exciting discovery involving a common mineral called manganese. Manganese is a nutrient that the body needs in very small amounts. It helps support many normal functions, including bone formation, metabolism, wound healing, and the activity of important enzymes.
Researchers recently found that manganese may also help reduce blood fats and clear artery plaques.
In the study, scientists gave different doses of manganese to mice that had cardiovascular disease. The results were surprising. The mice showed lower levels of cholesterol and triglycerides after receiving manganese. Even more importantly, the plaques inside their arteries became smaller.
This discovery could be very important because reducing plaque buildup is one of the biggest goals in preventing heart attacks and strokes.
To understand how manganese works, scientists looked closely at how fats travel through the body. Fats cannot move through the bloodstream on their own. Instead, they travel inside tiny particles called lipoproteins. These particles carry cholesterol and triglycerides through the blood to different parts of the body.
The body uses a transport system called COPII, short for coat protein complex II, to help package and move these fats. The researchers discovered that manganese affects the way this transport system works.
According to the study, manganese binds to the COPII system and changes its activity in a special way. Scientists described this effect as “bell-shaped.” This means that when manganese levels are within the right range, blood fat levels go down instead of increasing.
The finding is exciting because it suggests manganese may influence how the body handles fats at a very basic biological level.
Dr. Xiao Wang, one of the lead researchers involved in the study, said he is optimistic about the results. He believes therapies based on manganese could eventually help doctors prevent or treat heart disease more effectively in the future.
However, researchers also stress that the work is still in the early stages. So far, the studies have only been carried out in mice. Scientists still need to confirm whether manganese treatments are safe and effective for humans.
This step is very important because the human body is much more complex than animal models. Some treatments that work well in mice do not always work the same way in people. Researchers must also determine the safest dose because too much manganese can be harmful to the body.
Even so, the findings offer hope that a natural and potentially affordable treatment could one day help reduce plaque buildup and improve heart health.
Heart disease continues to place a huge burden on healthcare systems worldwide. It affects quality of life for millions of people and often leads to long-term disability and expensive medical treatment. Discoveries like this may eventually help reduce those burdens and save lives.
For now, doctors still recommend focusing on proven ways to protect heart health. Eating a balanced diet, staying physically active, avoiding smoking, managing stress, and controlling cholesterol and blood pressure remain some of the most effective steps people can take.
Researchers also continue studying how foods and natural compounds may affect heart health. Some studies suggest foods such as oranges and black beans may help lower the risk of obesity, diabetes, and heart disease. Scientists are also exploring new medications and lifestyle approaches to reduce the chances of heart attacks and strokes.
The new research about manganese and artery plaque was recently published in the journal Life Metabolism.
