Study information
Scientific title
The effects of sitagliptin (Januvia®) on myocardial performance in patients with coronary artery disease
Acronym
Study hypothesis
In patients with insulin resistance (independent of type two diabetes mellitus) and coronary disease, sitagliptin will promote myocardial glucose utilisation and protect the heart against post-ischaemic left ventricular dysfunction and improve the myocardial response to dobutamine stress.
Ethics approval
Ethics approval received from the Cambridge Research Ethics Committee 2 on the 1st May 2008 (ref: 08/H0304/22).

Condition
Coronary artery disease
Intervention
Subjects undergo two dobutamine stress echoes (DSE) (which last about half an hour) one week apart. Before the control DSE they are given a 75 g solution of glucose to drink. Before the other DSE they are given a single, oral dose of 100 mg of sitagliptin (Januvia®) and a 75 g oral glucose solution. A number of different DSE measurements are then compared between the two scans.

Not Specified
Drug names
Sitagliptin (Januvia®)
Primary outcome measure
LV performance during dobutamine stress echocardiography (wall motion scoring and ejection fraction [EF]), taken at baseline, peak dobutamine stress and in recovery for each DSE.
Secondary outcome measures
1. Tissue Doppler
2. Strain imaging
3. Strain rate
These outcome measures are taken at baseline, peak dobutamine stress and in recovery for each DSE.
