Greater gain leads to bigger loss in Japanese follow-up

Stent restenosis is determined mainly by the degree of luminal increase, regardless of the vessel size, according to a five-year Japanese study. Dr Naoya Hamasaki and a team from Kokura Memorial Hospital in Kikayushu studied restenosis in the 547 consecutive lesions in native coronary arteries which had satisfactory angiographic analysis before and after stenting and at three and six month follow up between February 1990 and February 1995.
