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.
Gazes et al. (1959) studied this question.
