The risk of CIN after PCI can be simply assessed using readily available information. This risk score can be used for both clinical and investigational purposes.

Restenosis at the site of an endoluminal procedure remains a significant problem in the practice of interventional cardiology. We present current data on intimal hyperplasia, which identify the major role of endothelial cells (ECs) in the development of restenosis. Considering endothelial denudation as one of the most important mechanisms contributing to restenosis, we focus more attention on methods of accelerating restoration of endothelial continuity. Prevention of restenosis may be achieved by promoting endothelial regeneration through the use of growth factors, EC seeding, vessel reconstruction with autologous EC/fibrin matrix, and the use of estrogen-loaded stents and stents designed to capture progenitor ECs.

Occurring in nearly 1 in 70 patients, early ST is relatively common in acute coronary syndromes, occurs with similar frequency after anticoagulation with either heparin plus glycoprotein IIb/IIIa inhibitors or bivalirudin with or without IIb/IIIa inhibitors, and is predicted by diffuse atherosclerosis, suboptimal angiographic results, and inadequate pharmacotherapy.

PAD is often overlooked even in patients with known ischemic heart disease under specialist cardiovascular care. Overlooked PAD in this population increases in frequency with advanced age, in women, and in the presence of other traditional cardiovascular risk factors. Furthermore, the presence of PAD in this population identifies a subgroup with more severe form of CAD.
