Effects of Selective Coronary Embolization on Coronary Blood Flow and Coronary Sinus Venous Blood Oxygen Saturation in Dogs

Effects of selective coronary embolization on coronary blood flow and coronary sinus venous blood oxygen saturation in dogs.

• Reflex mechanisms affecting the coronary circulation have been postulated and described as participating in the profound fall in blood pressure frequently attending cardiogenic shock following acute coxxmary occlusion. The reflex mechanisms suggested as being responsible for potentiating the cause of sudden death in coronary artery disease are: (1) an intercoronary reflex, which is believed t...

Effects of Selective Coronary Embolization on Coronary Blood Flow and Coronary Sinus Venous Blood Oxygen Saturation in Dogs WITH SPECIAL REFERENCE TO CORONARY REFLEXES

• Reflex mechanisms affecting the coronary circulation have been postulated and described as participating in the profound fall in blood pressure frequently attending cardiogenic shock following acute coxxmary occlusion. The reflex mechanisms suggested as being responsible for potentiating the cause of sudden death in coronary artery disease are: (1) an intercoronary reflex, which is believed t...

Coronary Blood Flow , Myocardial Oxygen

The effects of thyroid hormone excess on myocardial hemodynamics and carbohydrate metabolism were determined in a group of subjects, and the findings compared with those obtained in a group of normal individuals. The results indicate that in thyrotoxicosis there tends to be an increase in coronary blood flow and myocardial oxygen consumption and a normal per cent extraction of oxygen by the myo...

Measurement of Coronary Sinus Blood Flow

In 14 subjects with normal coronary arteries the mean coronary sinus blood flow was 122 25 mI/min (range, 83 to 159 ml/min). The blood flow computed per 100 g of left ventricle was 82 + 16 ml/min, which is in the range of values obtained by nitrous oxide and coincidence counting methods. In 35 patients with arteriographically confirmed coronary artery disease the mean flow was similar (128 + 20...
