Study type | Observational |
To find out the pharmacokinetic and genetic risk factors involved in muscular side effects
(myalgia) associated with statin therapy. To learn better ways of identifying risk factors
associated with muscle side effects during statin therapy. To perform laboratory analysis to
identify factors predicting future outcomes. The genetic material, in combination with other
medical information and blood tests, will be available to researchers studying genetic and
other factors that contribute to myalgia caused in some patient population on statin
medication.
Patients on statin are selected for this study. This study will recruit 1500 subjects from
National heart Centre Singapore over a period of 2.5 years.
Participation in the full study includes the donation of genetic material. However, subjects
have the option of not having blood subjected to genetic analysis and still participate in
the study. In this case, blood samples will only be analyzed for the statin drug content.

Eligibility |
Inclusion Criteria: - For myopathy cohort: 1. Subjects are/were on any statin drugs at any dose 2. Subjects reported/ diagnosed with myopathy =10X normal CK levels 3. Myopathy in subjects were statin induced For myalgia cohort: 1. Subjects are on either Simvastatin or Atorvastatin 2. If subject experience muscle symptoms without CK elevation (myalgia), it should be statin induced 3. Compliance to five consecutive statin doses prior to sample collection For the myalgia subgroup (n=30) for intra-individual variability assessment: 1. Subjects are on either Simvastatin or Atorvastatin 2. If subject experience muscle symptoms without CK elevation (myalgia), it should be statin induced 3. Subjects are willing to provide two blood samples during each of the 3 separate visits 4. Compliance to five consecutive statin doses prior to sample collection Exclusion Criteria: - 1. Unable or unwilling to give written informed consent 2. Subjects who are pregnant or breast feeding |
