That means it is determined by this equation: Coronary O2 delivery = Coronary blood flow × (sO2 × ceHb × BO2 ) + (PaO2 × 0.003) Where Coronary blood flow = 80-160ml/100g/min (wide range of reported values)

WebJul 31, 2015 · Myocardial perfusion imaging (MPI) is a non-invasive imaging test that shows how well blood flows through (perfuses) your heart muscle. It can show areas of the heart muscle that aren’t getting enough blood flow. This test is often called a nuclear stress test. It can also show how well the heart muscle is pumping. WebFollowing occlusion of a coronary artery, the perfused myocardium turned violet (the effect of 1.8% gentian violet) and the AAR was left unstained . The left ventricle was dissected from the rest of the heart and sliced transversally at a thickness of 8–10 mm and immersed in 2% TTC (2,3,5-triphenyltetrazolium) solution for 20 min at 37°C.
