Key result
Statin-induced myalgias and elevated creatine kinase were associated with impaired calcium homeostasis (abnormal in vitro contracture tests in 7 of 9 patients) but normal mitochondrial function.
Why the study?
Does statin treatment impair calcium homeostasis or mitochondrial function in patients with statin-induced myotoxicity?
Observational (n=11)
Does statin treatment impair calcium homeostasis or mitochondrial function in patients with statin-induced myotoxicity?
Statin-induced myotoxicity may be related to impaired calcium homeostasis rather than mitochondrial dysfunction, suggesting caution in patients susceptible to malignant hyperthermia.
No takes yet. Share an insight, caveat, or question.
May implicate calcium dysregulation over mitochondrial dysfunction in statin myotoxicity; hypothesis-generating and should not yet change practice.
Guis et al. (2006) conducted an observational in Statin-induced adverse effects (myalgias and increased creatine kinase) (n=11). Statin treatment was evaluated on Calcium homeostasis and mitochondrial function assessed via in vitro contracture tests (IVCTs), histology, and 31P-MRS. Statin-induced myalgias and elevated creatine kinase were associated with impaired calcium homeostasis (abnormal in vitro contracture tests in 7 of 9 patients) but normal mitochondrial function.
