Abstract

Purpose: While some work has been done on Health-Related Quality of Life (HRQoL) in statin users, none has focused specifically on statin-associated muscle symptoms (SAMS) sufferers. The objective was to assess self-reported HRQoL, before and after statin withdrawal, in patients reporting SAMS. We hypothesized that the presence of SAMS associated with decreased self-reported physical and mental well-being.

Methods: Patients (50 men/28 women [M/W], aged 49 ± 9 years [Mean ± SD]) in primary cardiovascular prevention were recruited into three cohorts: statin users with (SAMS, 29 M/18W) or without symptoms (No SAMS, 10 M/5W) and controls (11 M/5W). The Short Form 36 Health Survey (SF-36) was used to assess HRQoL. All variables were measured before and after 2 months of statin withdrawal, and repeated measures analyses were used to verify withdrawal and group effects as well as their interaction.

Results: SF-36 physical and mental component scores (respectively, PCS and MCS) were lower in the SAMS group compared with other groups (both p < 0.01). Statin withdrawal led to an increase in LDL cholesterol for statin users (+69.0%, p < 0.01) and an improvement in well-being in the SAMS group, other groups showing no change. A time x category interaction (p = 0.02) was seen for PCS and post hoc analyses showed that statin withdrawal improved PCS and MCS (respectively, +12.5% [ES 0.77] and +5.1% [ES 0.27], both p < 0.05) in the SAMS group.

Conclusion: Patients self-reporting SAMS showed improved HRQoL following drug withdrawal, but this was mirrored by a rise in LDL cholesterol. These findings should be considered by clinicians in the evaluation and follow-up of treatment with statins.
