Abstract
AIM: Statins are generally well-tolerated but some patients develop adverse events and down-titrate or discontinue statins. It is important to understand the frequency of dyslipidemia patients with the inability to continue statins. The aim of the present study was to identify the frequency of high-risk dyslipidemia patients who are unable to take or not taking statins for any reason using Japanese hospital claims database. METHODS: 2,527,405 dyslipidemia patients with atherosclerotic cardiovascular disease were investigated between April 2008 and September 2017. Definition 1 included statin discontinuation or down-titration with non-statin lipid modifying therapy (LMT) prescription, rhabdomyolysis or muscle-related symptoms with statin down-titration or discontinuation, or prescription for ≥3 statin types. Definition 2 included all components of Definition 1 in addition to statin down-titration or discontinuation for any reason. Patients never given statins but who started non-statin LMT were considered as Definition 3. The achievement rate of the target LDL-C level was investigated. RESULTS: Among 54,296 patients with statin prescription, 2.32% and 48.38% patients were identified as Definition 1 and 2, respectively. Of eligible patients, 13.16% patients were identified as Definition 3. The achievement rate of target LDL-C level was lower in patients meeting each definition than not satisfying each definition. CONCLUSIONS: There is a proportion of high-risk dyslipidemia patients unable to take or not taking statins for any reason, and it is associated with lower achievement rates of target LDL-C levels. Suboptimal management of LDL-C is directly associated with residual cardiovascular risk and implementation of alternative therapeutic options in addition to existing LMT is warranted.
