Correction of hypothyroidism and vitamin D insufficiency improves statin tolerance, claims study
USA: Statin tolerance may be improved by either correcting vitamin D insufficiency/deficiency and/or subclinical hypothyroidism or changing from a lipophilic statin to water-soluble statin (or lipophilic statin with minimal systemic exposure), a recent study has found. The study was published in the journal High Blood Pressure & Cardiovascular Prevention.
Globally, atherosclerotic cardiovascular disease (ASCVD) is the leading cause of mortality and morbidity. Statins are medications that are used for primary and secondary prevention of ASCVD. Intolerance due to statin-associated myalgias decreases long-term adherence, thus muting potential benefits.
Considering the above, Robert Solomon, Division of Cardiology, Ascension St. John Hospital, Detroit, Michigan, United States, and colleagues aimed to determine whether a transition from a lipophilic statin to a water-soluble statin or correction of subclinical hypothyroidism and vitamin D insufficiency/deficiency (metabolic abnormalities) betters statin tolerance.
For this purpose, the authors did a retrospective analysis of the data from patients suffering from statin intolerance. Patients intolerant to a lipophilic statin were changed to a water-soluble statin. Patients with a vitamin D insufficiency/deficiency or subclinical hypothyroidism were re-challenged with a water-soluble statin (or lipophilic statin with minimal systemic exposure) following correction of the metabolic abnormality.
The study led to the following findings:
- One hundred sixty-nine patients were statin intolerant. 86% (n = 145) were white and 48% (n = 81) were male. Eighty-two of these patients had one or both metabolic abnormalities. The remaining patients (n = 87) had no metabolic abnormality, however, they could not tolerate a lipophilic statin.
- 72% (n = 73) of eligible patients (n = 101), defined as those with a corrected metabolic abnormality or without a metabolic exception on a lipophilic statin, were able to tolerate a water-soluble statin or lipophilic statin with minimal systemic exposure.
- 75% (n = 127) of this total cohort met their LDL-C goal.
"Our findings suggest either correction of vitamin D insufficiency/deficiency and/or subclinical hypothyroidism or a change from a lipophilic statin to water-soluble statin (or lipophilic statin with minimal systemic exposure) improves statin tolerance," the researchers conclude.
