Do patients with acute myocardial infarction and angina pectoris have increased plasma catecholamine concentrations compared to normal subjects and patients with noncardiac pain?
Plasma catecholamines are elevated in acute myocardial infarction and exercise-induced angina pectoris compared to controls.
Urinary catechol amines have been shown to be increased in a few cases of acute myocardial infarction. The present study shows that patients with acute myocardial infarction and with angina pectoris (after exercise) have an increase in plasma catechol amines as compared to normal subjects before and after exercise and as compared to patients with noncardiac types of pain. The significance of these findings is discussed.
Gazes et al. (Fri,) studied this question.
