Evaluating Statin Tolerability in Historically Intolerant Patients After Correcting for Subclinical Hypothyroidism and Vitamin D Insufficiency.
INTRODUCTION: Atherosclerotic cardiovascular disease (ASCVD) is the major cause of morbidity and mortality worldwide. Statins provide primary and secondary ASCVD prevention. Intolerance due to statin-associated myalgias reduces long-term adherence, thus muting potential benefits. AIM: Our analysis sought to determine whether transition from a lipophilic statin to a water-soluble statin, or correction of subclinical hypothyroidism and/or vitamin D insufficiency/deficiency (metabolic abnormalities), improved statin tolerance. METHODS: We performed a retrospective analysis of the data from patients referred to our lipid clinic because of statin intolerance. Patients intolerant to a lipophilic statin were switched to a water-soluble statin. Patients having vitamin D insufficiency/deficiency or subclinical hypothyroidism were re-challenged with a water-soluble statin (or lipophilic statin with minimal systemic exposure) after correction of the metabolic abnormality. RESULTS: 169 patients were statin intolerant. 86% (n = 145) were white and 48% (n = 81) were male. 82 of these patients had one or both metabolic abnormalities. The remaining patients (n = 87) had no metabolic abnormality, however, were unable to tolerate a lipophilic statin. 72% (n = 73) of eligible patients (n = 101), defined as those with a corrected metabolic abnormality or without a metabolic abnormality on a lipophilic statin, were able to tolerate a water-soluble statin or lipophilic statin with minimal systemic exposure. In addition, 75% (n = 127) of this total cohort met their LDL-C goal. CONCLUSIONS: Our findings suggest that either correction of subclinical hypothyroidism and/or vitamin D insufficiency/deficiency or transition from a lipophilic statin to water-soluble statin (or lipophilic statin with minimal systemic exposure) improves statin tolerance.
