Correlation of peak aortic and carotid flow acceleration during coronary occlusion in conscious baboons



Correlation of peak aortic and carotid flow acceleration during coronary occlusion in conscious baboons



Clinical Science and Molecular Medicine 48(4): 243-246



1. Peak blood flow acceleration measured in the common carotid artery was compared with peak flow acceleration measured in the ascending aorta of three baboons. 2. The response to occlusion for 60s of the circumflex branch or the anterior descending branch of the left coronary artery was investigated. 3. Both accelerations decreased approximately to the same extent. Peak aortic flow velocity, stroke volume and cardiac output also decreased but to a smaller extent. 4. It is concluded that peak aortic flow acceleration is a sensitive index of myocardial function during acute coronary occlusion in conscious primates and that peak carotid flow acceleration is an indirect measure of myocardial performance under the same conditions.
