Morphological Characteristics of the Culprit Lesion Correlate With the Angiographic Flow Grade Following Thrombolysis in Myocardial Infarction. An Optical Coherence Tomography Study
Background: Intravenous thrombolysis fails to restore blood flow in a significant percentage of patients with ST-elevation myocardial infarction (STEMI). It remains unknown, whether certain morphological characteristics of the culprit lesion (CL) can predict the success of thrombolysis. We hypothesized that the thickness of the fibrous cap and the incidence of plaque rupture at the CL, as measured by Optical Coherence Tomography (OCT), may correlate with the outcome of thrombolysis. Methods: We prospectively enrolled 55 consecutive patients with STEMI that were treated with thrombolysis 6 hours from symptom onset. All patients underwent coronary angiography within 24 hours from thrombolysis. We estimated ...
