Prevalence of Self-Reported Muscle Pain Among Statin Users From National Guard Hospital, Riyadh

Abstract

BackgroundStatin, a hydroxymethylglutaryl-coenzyme A reductase inhibitor, is one of the commonly used lipid-lowering drugs that is used for lowering lipid levels in the body. Muscle pain is a commonly reported adverse effect of statins, yet little is known about the prevalence of muscle pain and statin use in the general population.MethodsThe cross-sectional study was conducted in National Guard Hospital, Riyadh, Saudi Arabia. All study subjects were adult statin users aged 18 years old or above. A total of 313 patients were included in the study. The study was conducted based on a questionnaire distributed among patients according to inclusion and exclusion criteria.ResultsAmong 313 statin users, patients underwent cardiac catheterization (39, 12.5%), stress test (62; 19.8%), percutaneous coronary intervention (three; 1.0%), and coronary artery bypass graft (six, 1.9%), while 203 patients didn't have any intervention (64.9%). Most of the study subjects were on atorvastatin (139; 44.4%).The prevalence of muscle pain was 73.5%; 95% Cl= (68.4% - 78.1%). The most common sites of pain were lower limb pain (160; 51.1%), upper limb pain (145; 46.3%), and trunk pain (96; 30.7%). The common types of pain were joint pain (52; 16.6%), muscle weakness (51; 16.3%), muscle aches (43; 13.7%), and muscle cramps (41; 13.1%); and patients who reported that they stopped statin at some point because of muscle pain were 92 (29.4%).ConclusionStatins are important for managing and preventing ischemic heart diseases. Our study found that muscle pain is highly associated with statin use with a prevalence of 73.5%, which causes many patients to tend to stop taking their medication. Therefore, preventing the side effects by adjusting the proper dose or switching to another type of statin for high-risk patients will help them to continue using the drug. Also, it is important to rule out secondary causes of myopathy such as physical activity, fracture, thyroid dysfunction, or infection.
