Lipoprotein(a) in restenosis after percutaneous transluminal coronary angioplasty and coronary artery disease

Abstract

Background: The purpose of the study was to investigate the relation of lipoprotein(a) and serum lipid parameters to restenosis after percutaneous transluminal coronary angioplasty (PTCA) and to assess the association of these same biochemical markers to coronary artery disease (CAD) in individuals with angiographically defined normal and diseased coronary arteries. Methods and Results: Sixty-two patients with successful PTCA had follow-up angiography at 35±10 weeks. Restenosis occurred in 21 male patients (46%) and 6 female patients (38%).
