38. “All this stent affair is a direct continuous of an non-responsible behavior of the cardiologist community. We are talking about many patients who are living with a ‘time-ticking bomb’ in their body. The cardiologists are ‘light headed’ in their attitude towards repeated revascularization procedure. If the patients needs more and more catheter-based procedures, their quality of life would be jeopardized and deteriorate.” “The cardiologists are the ‘gate keepers’ as they both diagnose and treat the cardiac patients. When the poor patient lay on the table and the a catheter is inserted into his groin, he does not get a fair chance to decide what is best for him, e,g, stent or surgery. The tremendous pressure of the stent maker companies with the financial interest existing in the private catheterization sector, are the reason that patients would undergo catheterizations again and again without obtaining the relevant information concerning their situation. Watch for your “Team” member! Yediot Journal 17.12.2006 “Stents in the arteries: a ticking bomb or a huge achievement?”

39. www.escardio.org/guidelines Evidence basis for myocardial revascularisation Optimal medical therapy versus CABG ●Survival benefit of CABG in patients with Left Main or three vessel CAD, particularly when it involved the proximal LAD coronary artery ●Benefits were greater in those with severe symptoms, early ischaemia during stress testing and impaired LV function ●Both optimal medical therapy and CABG have improved lately

40. www.escardio.org/guidelines Evidence basis for myocardial revascularisation Optimal medical therapy versus PCI ●Most meta-analyses reported no mortality benefit but: –increased non-fatal peri-procedural MI –reduced need for repeat revascularisation with PCI ●COURAGE Trial –At a median follow-up of 4.6 years, there was no significant difference in the composite of death, MI, stroke, or hospitalisation for unstable angina –Freedom from angina was greater by 12% in the PCI group at one year but was eroded by five years

41. www.escardio.org/guidelines Joint 2010 ESC - EACTS Guidelines on Myocardial Revascularisation Ad hoc PCI is convenient for the patient, associated with fewer access site complications, and often cost-effective. Ad hoc PCI is reasonable for many patients, but not desirable for all, and should not be automatically applied as a default approach.
