Heart disease is one of the leading causes of death around the world. Millions of people suffer from heart attacks, strokes, and heart failure every year.
Doctors have long known that many of these problems can be prevented if people manage their cholesterol levels, blood pressure, and blood clot risks.
However, preventing heart disease often requires patients to take several different medications every day. For many people, especially older adults, remembering to take multiple pills can be difficult. The cost of several medications can also make treatment harder to maintain over the long term.
Researchers from Tehran University of Medical Sciences have been studying a simpler way to protect people from heart disease. Their research suggests that combining several common heart medications into one pill could greatly reduce the risk of serious heart problems.
This type of pill is called a “polypill.” Instead of taking four separate medicines, a person only needs to take one pill each day.
The polypill used in the study contains four medications that doctors have already used for many years. The first is aspirin, which is commonly used in small doses to reduce blood clotting. Blood clots can block blood vessels in the heart or brain, which may cause heart attacks or strokes. The second medicine is atorvastatin, a drug that lowers cholesterol.
High cholesterol can lead to the buildup of fatty material inside arteries, making it harder for blood to flow through the body.
The third medicine is hydrochlorothiazide, which helps lower blood pressure by helping the body remove extra salt and water. The fourth medication is enalapril, another drug that reduces blood pressure and helps protect the heart and blood vessels.
To test whether this combination pill could prevent heart problems, the researchers carried out a large study in Iran. The study included nearly 6,800 adults between the ages of 50 and 75. Some of the participants already had heart disease, while others were considered at risk because of their age or health conditions.
All participants received advice about healthy living, such as eating a balanced diet, staying active, and avoiding smoking. However, only half of the participants were given the polypill. The other half continued with the usual care provided by their doctors.
The researchers followed the participants for five years to see how many people developed serious heart problems. These problems included heart attacks, strokes, and heart failure. The results showed a clear difference between the two groups.
Among the people who took the polypill, about 6 percent experienced a major heart-related event during the study period. In comparison, about 9 percent of those who did not take the polypill had similar problems.
This difference means that the polypill reduced the overall risk of major heart problems by about 34 percent. Even after the researchers adjusted their calculations to account for other medications that participants might have been taking, the risk was still reduced by about 22 percent.
The researchers also noticed that people who took the polypill regularly and did not miss doses had the greatest protection. In this group, the risk of heart problems was reduced by more than 70 percent compared with those who did not take the pill consistently.
The scientists also examined which part of the polypill might be providing the strongest benefit. They found that lowering cholesterol seemed to play a particularly important role in reducing the risk of heart disease. While the pill also lowered blood pressure, the cholesterol-lowering effect appeared to have a stronger impact on preventing heart attacks and strokes.
This study suggests that a single combined pill could make heart disease prevention much easier for many people. In many parts of the world, especially in lower-income countries, people may not have easy access to regular medical care.
They may also find it difficult to afford several different medications. A simple, low-cost pill that combines multiple treatments could make prevention more accessible and easier to follow.
Even in wealthier countries, some patients struggle to keep up with complicated treatment plans that involve many pills taken at different times of the day. A polypill could simplify these routines and improve long-term treatment success.
The researchers believe that this approach could help millions of people reduce their risk of life-threatening heart conditions. By making prevention simpler and more affordable, the polypill could become an important tool in the global effort to reduce heart disease. The findings of this research were published in the journal The Lancet.
