Regional Myocardial Blood Flow
Do oxygen-derived free radicals, generated at the time of reperfusion, lethally injure viable, previously ischemic myocardium, damage vascular endothelium, and impair recovery of postischemic contractile function? To address these issues, 23 anesthetized open-chest dogs underwent 2 hours of left anterior descending coronary artery occlusion followed by 4 hours of reperfusion. Immediately prior ...
متن کاملRegional Myocardial Blood Flow
nary artery disease has provided an intense stimulus for expansion of our present knowledge of the coronary circulation. In the experimental animal laboratory, the electromagnetic flowmeter has proved to be an excellent tool by which one can study dynamic aspects of the coronary circulation. A flowmeter is clearly unsuitable for human investigation; therefore, the search for a simple method of ...
متن کاملMeasurement of regional myocardial blood flow with multiple colored microspheres.
BACKGROUND The use of radioactive microspheres (RM) for the measurement of regional myocardial blood flow (RMBF) is limited and inaccessible to many investigators due to radiation safety concerns and radioactive waste disposal problems. Therefore, a new method for the measurement of RMBF using colored microspheres (CM) was developed. METHODS AND RESULTS Polystyrene spheres (diameter, 15 +/- 0...
متن کاملMeasurement of myocardial blood flow.
This paper represents a review of the recent literature on techniques to measure myocardial blood flow in man. A short discussion on flow meters in followed by a more detailed discussion of the radionuclide techniques used to measure myocardial blood flow. The radionuclide techniques are discussed in two groups: (1) qualitative measurement of blood flow using static images; and (2) quantitative...
متن کاملMeasurement of Myocardial Blood Flow
A"CLOSED" method for the accurate measurement of myocardial blood flow is still to be achieved. In 1956, Henly et al. described an indicator-dilution technique for assessing myocardial blood flow. This approach led us to construct a suitable model for simulating a systemic-coronary circuit. Observations with this system suggested that an indicator-dilution technique might be applicable to measu...
