Coronary artery stenting has definitely been proven to improve results of percutaneous revascularisation in a large number of patients. Stenting reduces restenosis in large vessels above 3 mm diameter. Stenting has not solved the problem of restenosis but in spite of the inevitable in-stent restenosis due to neointimal proliferation seems to yield better long-term results than conventional PTCA. Adjunctive pharmacological treatment with aspirin and clopidogrel in combination with improved stent deployment techniques has reduced the incidence of subacute stent thrombosis. GP IIb/IIIa inhibition is a promising mean for the reduction of procedure related ischaemic events and complications not only with stent implantation but also with conventional PTCA. Other new devices may further influence the treatment choices of stenting versus conventional PTCA in the future. Novel approaches such as brachytherapy and molecular genetic approaches to reduce in-stent restenosis are currently being investigated but to date no conclusions can be drawn as to their future place in clinical practice. From a mechanistic standpoint it seems obvious to give all our efforts to protect patients with coronary atherosclerosis from loss of myocardium either with coronary artery bypass grafting or percutaneous revascularisation. As both approaches are palliative in nature, it may be useful to attempt percutaneous revascularisation in patients amenable to this therapy and thus obviate or delay the need for definitive revascularisation by coronary artery bypass grafting. At the end of this discussion we would like to remind that medical therapy for coronary artery disease is of utmost importance as all revascularisation procedures do not influence the underlying disease. Besides symptomatic relief of angina, treatment of heart failure, and other beneficial strategies to improve endothelial function, medical therapy with lipid lowering compounds together with risk factor control offers the possibility to delay progression of coronary artery disease.
