Chest pain is a frequent complaint in patients with dilated cardiomyopathy (DCMP). Myocardial blood flow, coronary circulation parameters and coronary sinus lactate content were measured in 14 patients with DCMP and 10 healthy subjects. Myocardial blood flow in DCMP was 53.1 +/- 3.3 vs. 66.3 +/- 4.9 ml/min/100 g in the control group (p less than 0.05), coronary driving pressure was 59.1 +/- 4.6 vs. 72.8 +/- 8.8 mmHg (p less than 0.01). Subendocardial flow index (DPTI/TTI) in DCMP was 0.76 +/- 0.12 vs. 1.15 +/- 0.19 (p less than 0.01). The lactate content in coronary sinus blood was greater (1.93 +/- 0.45 mmol/l) than in the control group (1.43 +/- 0.48) (p less than 0.05). These results suggest that in DCMP myocardial blood flow is decreased, and in the majority of patients lactate is produced. Thus, it is possible that pain in DCMP is of anginal origin.
