Figure 1From: 138 Relationship between coronary calcification and endothelium dependent coronary vaso-reactivity in asymptomatic diabetic patients without overt coronary artery diseaseEndothelium-dependent perfusion reserve(MPR), as a marker for coronary vaso-reactivity, is impaired in coronary arteries with any amount of calcification. MPR was calculated by measuring myocardial blood flow during rest and during immersion for 1 minute in cold-water by Cardiac MRI.Back to article page
