ABSTRACT
BACKGROUND: There is little data about the intravascular ultrasound (IVUS) findings in the patients with vasospastic angina, especially with respect to patterns of vascular remodeling. METHODS: Coronary spasm was documented by angiography and ECG evidence of ischemia in 36 patients after administration of ergonovine (cumulative doses up to 350 microgram). After relief of spasm using 1,000 microgram of intracoronary nitroglycerin, IVUS imaging was performed and analyzed using standard methodology. The 36 focal spasm sites were compared to the proximal and distal reference segments. RESULTS: The angiographic baseline minimum lumen diameter measured 1.78+/-0.66mm, which decreased to 0.66+/-0.38mm with ergonovine provocaton (pproximal reference) was present in 5; intermediate remodeling (proximal reference >spasm site >distal reference arterial area) was present in 7; and negative remodeling (spasm site arterial area
