Influence of glyceryl trinitrate and nifedipine on coronary sinus blood flow and global myocardial metabolism during coronary artery operation.
The effects of intravenous infusions of glyceryl trinitrate and nifedipine on systemic haemodynamic function, coronary haemodynamic function, and global myocardial metabolism were compared in two groups of eleven patients with unimpaired left ventricular function undergoing elective coronary artery operation who were anaesthetised with high dose fentanyl. Severe post-sternotomy hypertension dev...
متن کاملCoronary 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...
متن کاملMyocardial ammonia metabolism in patients with heart disease as revealed by coronary sinus catheterization study.
CORONARY VENOUS SAMPLING via coronary sinus catheterization is now generally accepted as the method of choice for in vivo studies of arterial venous differences in the level of various metabolites in the human myocardium.1-5 Most previous studies using this approach have dealt with the output and/or uptake of products of carbohydrate metabolism (glucose, lactate, pyru-vate),6, 7-15 ammonia and ...
متن کاملCoronary Flow, Ventricular Function, and Myocardial Metabolism
To evaluate coronary flow reserve during cardiac catheterization, intracoronary adenosine and papaverine have been used in the clinical setting. Although papaverine maximizes coronary blood flow, it induces several toxic side effects that reduce its desirability as a coronary dilator. This investigation was designed to compare the subselective intracoronary administration of papaverine with tha...
متن کاملMeasurement 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...
