%X OBJECTIVE: Statin-associated muscle symptoms (SAMS) are claimed to be frequent in clinical practice. We evaluated the prevalence and characteristics of patient-reported muscle symptoms (PRMS) attributed to drugs/nutraceuticals in hypertensive patients, focusing the attention on statin treatment.
RESULTS: Observational study on 390 consecutive outpatients. All patients were asked the following question: "Have you ever taken a drug/nutraceutical that you think gave you muscle symptoms?". Patients who answered "yes" were evaluated with a modified version of the SAMS-clinical index (SAMS-CI). Mean age: 60.5 ± 13.5 years (males 53.8%.). Patients who have ever taken a statin: 250. Patients who have never taken a statin: 140. Prevalence of PRMS (48.5% of the entire study population) did not differ between groups (p = 0.217). Only age, followed by number of drugs taken, was significantly associated with PRMS at multivariate analysis. A high prevalence of low scores to all the questions of "modified" SAMS-CI was found in both groups. Localization and pattern of PRMS did not differ between groups (p = 0.170). Timing of PRMS onset after starting the drug (p = 0.036) and timing of improvement after withdrawal (p = 0.002) were associated with statin therapy.
CONCLUSIONS: PRMS are highly prevalent among the hypertensive population and are believed to be drug-related, especially with aging and regardless of whether the drug taken is a statin or not. These findings are in line with the growing evidence that subjective muscle symptoms are often misattributed to statins, while they may more likely be related to the nocebo/drucebo effect or to other common undiagnosed conditions.
