MUscle Side-Effects of Atorvastatin in Coronary Patients (MUSE) -Follow-up Study

Plain-language summary

Statins are cornerstone treatment in secondary cardiovascular disease (CVD) prevention. Today, statin non-adherence (patients not taking their prescribed drug) remains a major public health concern, leading to adverse outcomes in terms of morbidity, mortality and healthcare costs. The principal reason for statin non-adherence and discontinuation is statin-associated muscle symptoms (SAMS). Objective SAMS diagnostics do not exist. We aim to unravel the pathophysiology of SAMS and develop diagnostic tools to differentiate real SAMS from muscle symptoms not related to the statin, among coronary patients with self-perceived SAMS. In this follow-up study we aims to determine the effect of 7 weeks open treatment with atorvastatin 40 mg/day, followed by 7 weeks open treatment with no lipid lowering treatment, on muscle symptom intensity in patients classified with confirmed statin-associated muscle symptoms (SAMS) (i.e. statin-dependent muscle side-effects) and non-SAMS in the MUscle Side-Effects of atorvastatin in coronary patients (MUSE) randomized double blinded cross-over trial. We have developed novel methods that will be used to measure atorvastatin metabolites and drug effect biomarkers directly in skeletal muscle and blood . The diagnostic accuracy of these biomarkers to differentiate real SAMS from non-SAMS will be evaluated. A new diagnostic tool may potentially be implemented to assess SAMS in the individual patient and enable personalized follow-up. It may also represent an important tool in the communication with patients misattributing their muscle symptoms to statins. The long-term results may be better quality of life and reduced morbidity, mortality and healthcare costs.

Exclusion Criteria: * First or recurrent diagnosis (myocardial infarction) or treatments (PCI or CABG) for a CHD event the a) past 12 months prior to study start in high risk patients (i.e. at least one of following comorbid conditions: systolic heart failure, \>1 previous myocardial infarction, kidney failure, diabetes, and smokers) and b) the past 6 months prior to study start in low risk patients without any of the co-morbid conditions mentioned above and in patients who are not taking a statin at all. * Patients with symptomatic peripheral artery disease and patients with familial hypercholesterolemia * Patient has any contraindications for atorvastatin listed in the Summary of Product Characteristics (i.e. known hypersensitivity to the ingredients, acute liver failure/ ALT \> 3 times upper limit of the normal range in blood at study start, pregnancy and breastfeeding ) * History of previous rhabdomyolysis, myopathy or liver failure due to statin treatment with CK \> 10 times upper limit of the normal range or ALT \> 3 times upper limit of the normal range. * Any condition (e.g. psychiatric illness, dementia) or situation, that in the investigator's opinion could put the subject at significant risk, confound the…
