Use of optical coherence tomography for intermediate coronary artery lesions

Aim. To compare the results of interventions for intermediate coronary lesions, which were operated via angiography and optical coherence tomography (OCT). Methods. We performed a study including 130 stable patients with intermediate coronary lesions (40%-70%). The first group (n = 65) underwent angiography control; the second group (n = 65) underwent OCT control. Morphometric coronary indicators were analyzed intraoperatively. During the 12-month follow-up period, major adverse cardiovascular events incidence, angina recurrence frequency, restenosis, and stent thrombosis were assessed. Results. More pronounced coronary changes were noted in the OC group, as evidenced by stenosis indicators (51.5% [45.2-68.4] vs. 78.6 [65.7-80.3], p = 0.012), lesion length (18.4 mm [15.6-20.3] vs. 26.8 [24.6-32.2], p = 0.038), and plaque instability frequency (4.6% [3/65] vs. 12.3% [8/65], p = 0.048). In the OCT group, decision to perform stenting was more common (33.8% [22/65] vs. 83.1%) [54/65], p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
