Webb5 maj 2024 · Myocardial ischemia occurs when the blood flow through one or more of your coronary arteries is decreased. The low blood flow decreases the amount of oxygen your heart muscle receives. Myocardial ischemia can develop slowly as arteries become blocked over time. Or it can occur quickly when an artery becomes blocked suddenly. Webb2 jan. 2024 · In this study, reduced physiologic 18 F-FDG uptake of the myocardium was associated with longer fasting duration, higher level of uric acid and HbA1c, and less frequency of regular exercise with vigorous activity. We demonstrated that fasting duration was significantly associated with myocardial FDG uptake.
