Clinical presentation and outcome of patients with ST-segment elevation myocardial infarction without culprit angiographic lesions.
Patients diagnosed with ST-segment elevation myocardial infarction (STEMI) are occasionally found to have no culprit lesion on coronary angiography and are classified as presenting with false-positive STEMI. The clinical presentation and outcomes of these patients need to be further explored. In this case-controlled study, 259 consecutive patients with true code STEMI were compared to 104 consecutive STEMI patients without culprit lesions on emergent coronary angiography. ⋯ However, after excluding the patients with out-of-hospital cardiac arrests from both groups, the difference was no longer significant (P = 0.40 and 0.34 respectively). The relative poor outcomes of patients with false-positive code STEMI reflect the severity of their underlying medical condition. Careful history and review of ECG may help differentiate this group from true STEMI.
