Diabetes drug may boost heart fuel use in patients with clogged arteries

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Provision of informed consent prior to any study-specific procedures 2. Female or male subjects aged between 40 and 75 inclusive.
