Insights
Diabetic patients with multi-vessel coronary disease benefit from surgical revascularization. Bilateral internal mammary artery grafts offer superior long-term outcomes compared to radial arteries, with no increased infection risk.
Area of Science:
- Cardiovascular Surgery
- Diabetic Medicine
- Vascular Biology
Context:
- Coronary multi-vessel disease in diabetic patients presents unique challenges for revascularization strategies.
- Percutaneous coronary interventions may offer less favorable long-term outcomes compared to surgical revascularization in this population.
- The optimal choice of arterial conduits for coronary artery bypass grafting in diabetics remains an area of active investigation.
Purpose:
- To systematically analyze the current literature on the use of arterial grafts in diabetic patients undergoing coronary revascularization.
- To compare the long-term efficacy and safety of radial artery versus internal mammary artery grafts in diabetic patients.
- To evaluate the impact of bilateral internal mammary artery grafting on survival and complications in diabetic individuals.
Summary:
- Diabetic patients with multi-vessel coronary disease experience superior long-term outcomes with surgical revascularization over percutaneous coronary interventions.
- The radial artery demonstrates a higher propensity for atherosclerosis in diabetics compared to the internal mammary artery.
- Bilateral internal mammary artery grafts are associated with better long-term survival in diabetic patients, without an obligatory increase in thoracic wound infections.
Impact:
- Diabetic patients should benefit from the utilization of a second internal mammary artery graft for coronary revascularization.
- A second internal mammary artery graft appears to be a more favorable conduit choice than a radial artery graft in diabetic patients, considering long-term patency and disease progression.
- These findings support the expanded use of bilateral internal mammary artery grafts in diabetic patients to improve long-term cardiac health and survival.
Abstract:
Surgical revascularization allows especially for the diabetic patient with coronary multi-vessel disease a superior long-termperspective compared to percutaneous coronary interventions. However, the specific advantages and also risks associated with the expanded use of arterial grafts as coronary conduits in diabetics are not clearly answered. A systemic analysis of the current literature underlines the following statements: The radial artery is, compared to the internal mammary artery, to a higher extent prone to atherosclerosis, especially in diabetic patients. Better long-term survival for patients with bilateral IMA-grafts has also been assessed for diabetic patients. The risk of thoracic wound infections is not obligatory increased for diabetics with double IMA-grafts. Revascularization with radial arteries can be performed with low perioperative risks. Long-term results or studies on radial artery bypass grafting especially in diabetics are not available. In our own experience (3,548 isolated coronary operations, 01/2001 until 05/2005), diabetic patients have no increased perioperative mortality, even when using more complex arterial grafting. Conclusively, diabetic patients should also significantly benefit from the use of the second mammary artery. Regarding conduit quality, a second IMA appears favorable over the radial artery.
