Diabetes and coronary revascularization
Coronary interventions in patients with vs.
without diabetes
  • Coronary Bypass Surgery
  • Higher mortality
  • More frequent complications
  • infections, delayed wound healing
  • Percutanous coronary angioplasty
  • Higher mortality
  • High restenosis rate
  • Increased rate of stent thrombosis
  • More frequent repeat revascularizations

Management of diabetes and glucose control
before, during and after PCI and CABG
Whenever possible, patients with diabetes should
be I C offered at least one and often
multiple arterial grafts

32
Unresolved issues
On the amount and quality of presently available
information
  • Limited
  • Retrospective
  • Therapy not updated
  • Mostly subgroup-based
  • Diabetes poorly described
  • Glucose lowering therapy undefined

33
Unresolved issues
On urgently needed information
  • Trials dedicated to diabetic patients
  • Accurately characterised patients
  • Well defined concomitant therapy
  • Carefully described glucose lowering drugs
  • Mode of revascularization
  • single vs. multivessel disease
  • optimised technique
  • The impact of tight glycemic control

Unresolved issues
