Type 2 diabetes is a long-term condition that affects how the body controls blood sugar. Over time, high blood sugar can damage blood vessels and nerves, increasing the risk of many serious health problems.
One of the biggest concerns for people with type 2 diabetes is heart disease. Even when blood sugar is fairly well controlled, diabetes itself raises the chance of heart attacks, strokes, and early death.
Statins are medications commonly used to lower LDL cholesterol, often called bad cholesterol. High levels of LDL cholesterol can cause fatty buildup in blood vessels, making them narrower and harder. This process increases the risk of heart attacks and strokes.
Because people with diabetes already face higher cardiovascular risk, statins are often prescribed. However, for many years doctors have debated whether statins are truly necessary for patients whose short-term risk of heart disease appears low.
A new large study suggests that this debate may need to be reconsidered. The research found that statins significantly lower the risk of death and serious heart-related problems in adults with type 2 diabetes, even among those considered to have a low chance of developing heart disease over the next 10 years. The findings were published in the journal Annals of Internal Medicine.
The study was led by researchers from the University of Hong Kong, who analyzed health records from the IQVIA Medical Research Data database in the United Kingdom. This database contains detailed medical information from general practices and allows scientists to track patient outcomes over many years.
The researchers wanted to understand how effective and safe statins are when used for primary prevention. Primary prevention means preventing a first heart attack or stroke before it happens.
The study included adults with type 2 diabetes between the ages of 25 and 84. None of the participants had a history of serious heart disease or major liver problems at the beginning of the study.
This allowed the researchers to focus on how statins affected people who had not yet experienced cardiovascular events. Participants were followed for up to 10 years, giving the researchers a long period to observe outcomes.
The researchers compared people who started statin treatment with those who did not. They grouped participants based on their estimated 10-year risk of developing cardiovascular disease. This type of risk score is commonly used by doctors to decide whether preventive treatments like statins should be prescribed.
The results were consistent and clear. Across all risk groups, people who took statins had lower rates of death from any cause and fewer major heart-related events. These events included heart attacks and strokes.
Importantly, even people classified as low risk benefited from statin use. This finding challenges the idea that statins are only useful for people who already face a high chance of heart disease.
The study suggests that short-term risk estimates may not fully capture the long-term dangers associated with diabetes.
While someone with diabetes may appear to have a low risk of heart disease over the next decade, the underlying condition still places stress on the heart and blood vessels over time. Statins appear to offer protection that extends beyond what short-term risk calculators predict.
Safety was also carefully examined. One concern with statin use is muscle-related side effects, known as myopathy. These symptoms can include muscle pain, weakness, or soreness.
The researchers found a very small increase in myopathy in one risk group, but overall the risk remained low. Another common concern is liver damage, but the study found no increase in serious liver-related problems among people taking statins.
These findings are important for both patients and doctors. For patients with type 2 diabetes, the study provides reassurance that statins may help protect against heart disease and early death, even if they feel healthy and are told their short-term heart risk is low. For doctors, the results suggest that treatment decisions should not rely only on short-term risk estimates.
The researchers concluded that statin therapy should be carefully considered for all adults with type 2 diabetes as part of long-term heart disease prevention. By focusing only on short-term risk, some patients may miss out on treatments that could help them live longer and avoid serious complications.
Overall, this large and long-term study adds strong evidence that statins offer meaningful benefits for people with type 2 diabetes across a wide range of risk levels. As understanding of diabetes and heart disease continues to improve, these findings may help shape future treatment guidelines and encourage a more preventive approach to care.
