Safety and efficacy of frequency-domain optical coherence tomography in evaluating and treating intermediate coronary lesions

Table 2 Two-dimensional quantitative coronary angiography findings pre-optical coherence tomography in the percutaneous coronary intervention and optimal medical therapy groups

Variable	OCT-guided PCI (n = 38)	OCT-guided OMT (n = 26)	P-value
Reference area, mm2	7.91 (5.61-10.45)	7.97 (6.01-11.16)	0.538
Minimum luminal area, mm2	1.97 (1.37-2.80)	2.40 (1.73-3.82)	0.029
Area stenosis %	74.02 ± 6.43	67.77 ± 6.44	0.001

Data are expressed as mean ± SD and n (%), or median and 25^th and 75^th. Percentiles for non-normal distribution. OCT: Optical coherence tomography; PCI: Percutaneous coronary intervention; OMT: Optimal medical therapy.
