Cardiac Imaging for Risk Stratification in Diabetes

Pharmacological stressors include dobutamine (a β-1-specific agonist), which increases heart rate, contractility, and arterial blood pressure, resulting in increased myocardial oxygen demand, and adenosine (a direct vasodilator) or dipyridamole, which act indirectly by inhibiting cellular uptake and breakdown of adenosine.
