Hydrocortisone reduces restenosis after stenting of small coronary arteries.

Stenting of small coronary arteries has been limited by high rates of restenosis, and restenosis after stenting has chiefly been attributed to inflammatory reactions resulting in cell proliferation and intimal hyperplasia. In order to suppress this inflammatory process, we examined the effects of hydrocortisone, an antiinflammatory agent, on restenosis after stenting in a nonrandomized retrospective registry. The study population consisted of 193 patients treated at two hospitals, who underwent stent implantations in coronary arteries of reference diameter <3 mm between February 1999 and September 2001.

The effect of hydrocortisone on reducing rates of restenosis and target lesion revascularization after coronary stenting less than 3 mm in stent diameter.

Objective: Stenting of small coronary arteries has always been limited by high rates of restenosis, and restenosis has mainly been attributed to inflammatory reactions resulting in cell proliferation and intimal hyperplasia. Based on our experience for several years, we retrospectively investigated the effect of hydrocortisone on reducing in-stent restenosis.

Patients And Methods: Study population consisted of consecutive 166 patients, 221 lesions, who electively underwent stent implantations stent diameter less than 3 mm into coronary arteries between February 1999 and October 2002.
