Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To characterize features of metabolic syndrome in volunteers. To undertake a randomised trial to determine whether treatment with a statin improves muscle microvascular blood flow.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

To characterise features of the metabolic syndrome, including body fat, insulin sensitivity, and liver fat together with muscle micorvascular blood flow.

To undertake a randomised controlled trial of atorvastatin 40 mg. o.d for 6 months to determine whether any of the above measures change with treatment.
