Association of angiographic morphology with high-sensitivity C-reactive protein levels in patients with coronary spastic angina.

Relationship between angiographic morphology and high-sensitivity C-reactive protein (hs-CRP) levels is not fully understood. The serum levels of hs-CRP levels were higher in focal than in diffuse vasospasm in patients with coronary spastic angina. Intravascular ultrasound showed greater plaque volume at the site of vasospasm in the focal vasospasm, in the absence of significant angiographic stenosis, whereas diffuse intimal thickening throughout the coronary arteries was observed in the diffuse vasospasm. The distinct differences in the hs-CRP levels may be closely associated with coronary plaque appearances.
