Endothelium-dependent coronary flow in ischemia reperfusion
(Gustav Fischer VerlagJenaAlemanha, 1997)
Coronary perfusion pressure as a determinant of ventricular performance
The results observed in this work support the view that coronary perfusion pressure affects ventricular performance independently of metabolic effects; a mechanism operating in beat-to-beat regulation is proposed.
Ausência de arteriosclerose na porção intramiocárdica das artérias coronárias: Um mistério a ser resolvido?
Several studies show that portions of intramyocardial coronary arteries are spared of arteriosclerosis, involving morphological, embryological, biochemical and pathophysiological aspects. Endothelial function is significantly ...

Total and regional coronary blood flow during acute coronary occlusion in anaesthetized and conscious dogs
Total and regional coronary blood flow was measured with microspheres labeled with 141Ce or 85Sr before and early after the occlusion of the anterior descending coronary artery. A radial gradient of flow was found in the ...
Endothelial and non-endothelial coronary blood flow reserve and left ventricular dysfunction in systemic hypertension
(Faculdade de Medicina / USP, 2009)
OBJECTIVES: We evaluated the impairment of endothelium-dependent and endothelium-independent coronary blood flow reserve after administration of intracoronary acetylcholine and adenosine, and its association with hypertensive ...
Is coronary sinus blood oxygen tension behavior determined by myocardial oxygen tension variation during cardiac reperfusion?
The relationship between coronary sinus blood oxygen tension (CSPO 2) and myocardial oxygen tension (MPO 2) variations during cardiac ischemia and reperfusion was studied in anesthetized open-chest dogs. Oxygen tension was ...
