Scientists at the University of Oxford have created a new calculator. It helps predict a person's risk of serious muscle problems from statins. This tool offers a more personal way to decide on statin treatment.
Statins are common medicines. They lower cholesterol and reduce the risk of heart attacks and strokes. However, many people worry about side effects, especially muscle issues. This worry often stops them from taking statins.
A New Tool for Personalized Decisions
The new calculator helps patients and doctors make better choices. It estimates an individual's risk of serious muscle disorders. This is more helpful than relying on general statistics.

The study also found a gap in treatment. More than 60% of people who should take statins are not. Some of these people face a high risk of heart attack or stroke. The calculator could improve discussions by giving personalized risk estimates.
How the Calculator Works
The calculator uses data from over 5.6 million anonymous health records in England. Researchers built the model with data from 1.7 million people. Then, they tested it with another 3.9 million records.
It looks at 22 health factors to estimate risk over one, five, and 10 years. These factors include age, sex, ethnicity, body mass index, and smoking status. It also considers existing health conditions, past muscle problems, vitamin D levels, and other medications.
The calculator is meant to be used with other tools, like QRISK. This way, patients and doctors can compare the benefits of preventing heart attacks and strokes with the risk of muscle disorders. This helps them decide if statin treatment is right.
Understanding Statin Side Effects
Statins are widely prescribed. But concerns about muscle problems often make people hesitant. The new calculator helps put these concerns into perspective. It gives individual risk estimates.
The study focused on serious muscle disorders that led to hospital stays or death. It did not look at common muscle aches. Many mild muscle symptoms reported with statins are not actually caused by the medicine. These symptoms should not stop people from taking statins.
Dr. Ting Cai, the lead author from the University of Oxford, noted that the risk of serious muscle disorders is very low for most people. For the few at higher risk, the calculator helps doctors discuss monitoring or other treatment options.
Professor James Sheppard, a senior author, added that treatment decisions often focus on preventing heart problems. This research helps by also providing information on the risk of side effects. Combining these two pieces of information leads to more personalized decisions.
The STRATIFY-StatinMD Risk Calculator is available through the Oxford University Innovation software store for academic use.
