Insights
Diabetes mellitus complicates coronary artery disease, increasing risks after percutaneous coronary intervention. Drug-coated balloons offer a promising scaffold-free alternative for diabetic patients undergoing PCI, potentially improving outcomes.
Area of Science:
- Cardiology
- Endocrinology
- Biomedical Engineering
Background:
- Diabetes mellitus (DM) significantly increases the risk and severity of coronary artery disease (CAD).
- Diabetic patients face higher risks of adverse events and stent-related complications after percutaneous coronary intervention (PCI) compared to non-diabetic individuals.
- Despite advancements in drug-eluting stents, long-term outcomes in diabetic patients remain a concern.
Purpose of the Study:
- To review the impact of DM pathophysiology on PCI outcomes.
- To explore the potential benefits of drug-coated balloons (DCB) in diabetic CAD patients.
- To summarize current evidence comparing DCB to other PCI techniques and suggest individualized treatment approaches.
Main Methods:
- Literature review of studies on DM, CAD, PCI, and DCB technology.
- Analysis of the pathophysiological mechanisms linking DM to adverse cardiovascular events.
- Synthesis of clinical trial data comparing DCB angioplasty with other revascularization strategies in diabetic patients.
Main Results:
- DM is associated with more complex atherosclerosis and a pro-thrombotic, inflammatory state, worsening PCI outcomes.
- Drug-coated balloons deliver antiproliferative agents directly to lesions without a metallic scaffold, offering a potential advantage.
- Evidence comparing DCB to other PCI techniques in diabetic populations is still evolving, necessitating further research.
Conclusions:
- DCB angioplasty presents a promising therapeutic option for diabetic patients with CAD, potentially mitigating risks associated with metallic stents.
- Further research is needed to fully elucidate the long-term efficacy and optimal use of DCB in this high-risk population.
- An individualized treatment strategy considering DM-specific factors is crucial for optimizing PCI outcomes in diabetic patients.
Abstract:
Diabetes mellitus (DM) is a major contributor to coronary artery disease (CAD) worldwide. Moreover, DM is associated with more extensive atherosclerotic disease, often with multivessel involvement and complex and vulnerable plaque characteristics, as well as an enhanced thrombotic and inflammatory environment. Altogether, these factors increase the risk of adverse events following percutaneous coronary intervention (PCI) compared to individuals with normal glucose levels. Despite latest generation drug-eluting stents provide better overall clinical outcomes compared with earlier generations, diabetic patients still experience short- and long-term stent-related complications, such as target-lesion revascularization, in-stent restenosis, and stent thrombosis. The development of drug-coated balloons (DCB) has provided a promising alternative in this setting. This innovative technology relies on the delivery of an antiproliferative agent directly to the target lesion without leaving any permanent metallic scaffold. However, the benefit of DCB-based revascularization for CAD patients with DM compared to other techniques as well as the effectiveness of preoperative and postoperative management in improving outcomes have not been fully addressed. This review aims to discuss the impact of DM pathophysiology on the outcomes of PCI and the potential mechanistic benefit of DCB angioplasty in diabetic patients with CAD. Finally, we summarize the results from all current evidence comparing DCB-based to other PCI techniques and propose an individualized approach for treating diabetic patients with CAD.
