Insights

Patients with diabetes undergoing complex multivessel percutaneous coronary intervention (PCI) guided by intravascular ultrasound (IVUS) have similar 1-year outcomes to those without diabetes. This study highlights comparable results for this high-risk group when managed with optimal stent expansion criteria.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • Data on clinical outcomes for diabetic patients undergoing intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) for multivessel disease is scarce.
  • Optimal stent expansion is crucial for successful PCI outcomes, particularly in complex cases.

Purpose of the Study:

  • To compare 1-year clinical outcomes between diabetic and non-diabetic patients who underwent multivessel PCI guided by IVUS.
  • To assess the impact of diabetes on outcomes in patients treated with IVUS-guided PCI aiming for optimal stent expansion.

Main Methods:

  • Prospective, multicenter, single-arm trial (Optimal Intravascular Ultrasound Guided Complex Percutaneous Coronary Intervention study).
  • 1,021 patients with multivessel disease underwent IVUS-guided PCI, including the left anterior descending artery.
  • Patients were stratified into diabetic (n=560) and non-diabetic (n=461) groups, with outcomes compared based on the prespecified OPTIVUS criteria.

Main Results:

  • The rate of achieving optimal stent expansion (OPTIVUS criteria) was similar between diabetic and non-diabetic groups (61.2% vs. 60.7%, p=0.83).
  • Diabetic patients had more complex coronary artery disease, evidenced by higher stent utilization and longer stent lengths.
  • The primary endpoint (composite of death, myocardial infarction, stroke, or revascularization) at 1 year was comparable: 10.8% in diabetics vs. 9.8% in non-diabetics (log-rank p=0.65).
  • Adjusted analysis showed no significant difference in the primary endpoint risk between groups (HR 0.97, 95% CI 0.65-1.44, p=0.88).

Conclusions:

  • In patients undergoing multivessel IVUS-guided PCI with contemporary management, diabetes does not appear to be associated with significantly different 1-year clinical outcomes.
  • Achieving optimal stent expansion with IVUS is feasible and yields similar results in both diabetic and non-diabetic patients with multivessel disease.
  • These findings suggest that IVUS-guided PCI can effectively manage complex multivessel disease in diabetic patients, leading to comparable outcomes to their non-diabetic counterparts.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Complications of Diabetes Mellitus

Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...

Diabetic Foot Ulcer

Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
