摘要
This study evaluated the potential consequences of the redefined joint European/ American electrocardiographic criteria for an established myocardial infarction (MI). New and previous diagnostic Q-wave criteria were used in patients with stable angina pectoris. Seventy-nine patients with and 77 patients without a documented previous MI were compared using the results of myocardial perfusion imaging at rest as a reference. With the new Q-wave criteria, 71% of the former group and 40% of the latter had evidence of established MI compared with 33% and 3% when using the previous criteria (p < 0.0001). Sensitivity, specificity, and positive and negative predictive values were 71%, 60%, 64%, and 67% for the new criteria versus 33%, 97%, 93%, and 59% with the previous criteria. These data suggest that that the new Q-wave criteria may be too nonspecific, resulting in an inappropriately high number of false-positive results. (c) 2006 Elsevier Inc. All rights reserved.
