• W2082505870 abstract "Coronary vasodilator reserve is reduced in some patients with a history of chest pain and angiographically normal coronary arteries. ECG changes suggestive of myocardial ischemia during exercise also can be demonstrated in a subset of these patients.We have investigated the correlation between coronary vasodilator reserve, assessed with 13N-labeled ammonia and positron emission tomography, and the ECG during exercise stress in 45 patients with a history of chest pain, angiographically normal coronary arteries, and a negative ergonovine test. ST segment depression on the ECG during exercise was present in 29 of 45 patients. Mean resting left ventricular blood flow was 1.04 +/- 0.22 ml.min-1.g-1; it increased to 1.32 +/- 0.47 ml.min-1.g-1 (p less than 0.01 versus baseline value) during atrial pacing and to 2.52 +/- 0.96 ml.min-1.g-1 (p less than 0.01 versus baseline value) after dipyridamole (0.56 mg/kg i.v.). No regional flow defects could be demonstrated in any patient during pacing or after dipyridamole. Myocardial flows after dipyridamole, however, did not show a normal frequency distribution (Kolmogorov-Smirnov test), and two patient populations could be identified. Twenty-nine (67%) patients had a mean left ventricular flow of 3.02 +/- 0.33 ml.min-1.g-1 after dipyridamole (range, 2.13-5.46 ml.min-1.g-1), and 14 (33%) patients had a mean flow of 1.48 +/- 0.29 ml.min-1.g-1 (range, 1.06-2.04 ml.min-1.g-1, p less than 0.01 versus the high-flow group).Approximately one third of patients in our series showed a reduced coronary vasodilator reserve. Although 12 of 14 patients in the low-flow group had ST segment depression during exercise stress, 16 of 29 patients in the high-flow group also had ST segment depression during exercise stress. Therefore, despite a good sensitivity (86%) in identifying patients with a blunted increment of coronary flow, the ECG response during exercise stress appears to have a rather low specificity (45%). This suggests that factors other than reduced coronary reserve and myocardial ischemia may play a role in the genesis of the ST segment depression in these patients." @default.
