To evaluate myocardial catecholamine balance in heart failure, systemic hemodynamics, coronary sinus blood flow, and arterial and coronary sinus venous norepinephrine (NE) and epinephrine (E) concentrations were determined in 30 patients with chronic left ventricular failure (CHF), and in 25 patients with angina pectoris (AP) but without heart failure. In the group with CHF, stroke work index was lower (CHF 20 ± 9, AP 53 ± 13 g-m/m2, p <0.001) and pulmonary capillary wedge pressure higher (CHF 28 ± 8, AP 11 ± 4 mm Hg, p < 0.001), indicating depressed left ventricular function. Coronary sinus blood flow was similar in 2 groups (CHF 97 ± 70, AP 73 ± 32 ml/min, difference not significant). In the group with CHF, arterial (634 ± 582 pg/ml) and coronary sinus venous (1,038 ± 1,014 pg/ml) NE concentrations were significantly higher than in the group with AP (arterial 185 ± 135, coronary sinus 231 ± 167 pg/ml, p <0.001). The net myocardial NE release in patients with CHF was approximately 20 times higher than that in patients with AP (CHF 38,548 ± 48,622, AP 2,245 ± 10,242 pg/min, p <0.001). Arterial E and myocardial E uptake was similar in both groups. Although mechanisms for increased myocardial net NE release remains unknown, it probably represents enhanced cardiac sympathetic tone in response to heart failure.
