Millions of people around the world take statins every day to lower cholesterol and protect their hearts. These medicines are commonly prescribed to people who have high cholesterol, heart disease, or a history of blocked arteries.
Doctors use them to reduce the risk of dangerous problems such as heart attacks and strokes. Among the many statins available today, rosuvastatin and atorvastatin are two of the most widely used.
Both medicines work by lowering LDL cholesterol, often called “bad” cholesterol. High levels of LDL cholesterol can build up inside blood vessels over time and form fatty plaques.
These plaques can narrow or block arteries, making it harder for blood to flow properly. If a plaque breaks open, it can cause a heart attack or stroke. Because of this, lowering LDL cholesterol has become one of the main goals in preventing heart disease.
Even though rosuvastatin and atorvastatin are both commonly used, doctors and patients have long wondered whether one drug is better than the other. A major new study called LODESTAR has now provided important information about how these two medications compare in real patients with heart disease.
The study involved 4,400 adults with coronary artery disease. Coronary artery disease happens when the blood vessels that supply the heart become narrowed or blocked.
This condition is one of the leading causes of heart attacks and death worldwide. People with this disease often need long-term treatment to lower cholesterol and reduce stress on the heart.
The participants in the study were randomly assigned to take either rosuvastatin or atorvastatin. Researchers then followed them for three years between 2016 and 2019. The goal was to compare how well the two drugs protected people from major health problems.
The researchers looked closely at serious outcomes such as heart attacks, strokes, death, and surgeries or procedures used to open blocked arteries. After studying the results, they found that both drugs worked very similarly. There were no major differences between the groups in the number of heart attacks, strokes, deaths, or artery-opening procedures.
This means both rosuvastatin and atorvastatin appear to provide similar protection for people with coronary artery disease. For patients and doctors, this is important news because it suggests that either medication can be an effective option for reducing heart-related risks.
However, the study also uncovered some differences that may matter when choosing between the two drugs. People taking rosuvastatin had slightly lower LDL cholesterol levels compared with those taking atorvastatin. Lower cholesterol is usually seen as a good thing because it is linked to lower heart risk.
But researchers noticed that the rosuvastatin group also had a higher chance of developing type 2 diabetes that required medication. In addition, people taking rosuvastatin had a slightly higher rate of cataract surgery.
Cataracts happen when the lens of the eye becomes cloudy, causing blurry vision and difficulty seeing clearly. Cataract surgery is common, especially among older adults, but the finding still raised questions about possible side effects linked to the medication.
The study highlights an important lesson in medicine. A treatment may provide strong benefits while also carrying certain risks. In this case, rosuvastatin may lower cholesterol slightly more than atorvastatin, but it may also increase the chance of other health problems in some people.
Because of this, researchers say the choice of statin should not be based only on cholesterol numbers. Doctors and patients should also think about the person’s overall health, family history, risk of diabetes, eye health, and other medical conditions when deciding which medication is the better fit.
The researchers also noted some limitations in the study. All participants were of Asian backgrounds, so it is not yet clear whether the same results would appear in people from other ethnic groups. The study also lasted only three years, which may not be long enough to fully understand the long-term effects of these medicines.
Even with these limitations, the research provides valuable new information for doctors treating people with heart disease. It reminds people that medications are only one part of staying healthy.
Experts continue to stress the importance of healthy lifestyle habits alongside medicine. Eating a balanced diet, staying physically active, avoiding smoking, and controlling blood pressure can all help reduce heart disease risk.
Some studies suggest that diets rich in vegetables and healthy foods may help lower blood pressure and improve heart health. Other research has explored how foods such as eggs or milk may affect the risk of heart disease and other illnesses.
The study was published in the medical journal BMJ. It adds to growing research showing that medical decisions are often about balancing benefits and risks rather than finding one “perfect” treatment.
For people taking statins, the findings may help support more informed conversations with doctors about the best option for their long-term health.
