Figure 2 Relationship Between the Spasm-Positive Artery and the Advance of Coronary Lesions

Target vessel revascularization was more frequent in the spasm-positive arteries (PAs) (31.7%) than in the spasm-negative arteries (NAs) (18.2%, p = 0.014). De novo lesions, including acute coronary syndrome lesions, were observed in 25 of 400 PAs and in 3 NAs (p = 0.00044). Acute coronary syndrome (ACS) was observed in 10 of 400 PAs and in 0 of 301 NAs (p = 0.0057).
