Insights

Sirolimus-eluting stents (SES) show similar long-term cardiac event rates compared to bare metal stents (BMS) in patients with diabetes. However, SES may reduce major adverse cardiac events in diabetic patients with coronary artery disease.

Area of Science:

  • Cardiovascular Medicine
  • Interventional Cardiology
  • Diabetes Mellitus Research

Context:

  • Coronary artery disease (CAD) management involves percutaneous coronary intervention (PCI) with stent implantation.
  • Diabetic patients represent a high-risk population for adverse cardiovascular outcomes post-PCI.
  • Evaluating the long-term efficacy of drug-eluting stents versus bare metal stents in this population is crucial.

Purpose:

  • To compare the long-term outcomes of sirolimus-eluting stents (SES) versus bare metal stents (BMS) in patients with coronary artery disease (CAD), specifically analyzing the impact of diabetes mellitus.
  • To assess the occurrence of major adverse cardiac events (MACE) and MACE-free survival rates at one year following PCI in diabetic and non-diabetic patients treated with SES or BMS.

Summary:

  • A study of 1004 patients (84 diabetic, 250 non-diabetic with SES; 168 diabetic, 502 non-diabetic with BMS) found similar MACE rates and one-year MACE-free survival between diabetic and non-diabetic patients receiving SES (4.8% vs. 3.6% MACE).
  • Patients receiving BMS showed significantly higher MACE occurrence (31.0% vs. 21.7%, P=0.015) and lower one-year MACE-free survival (74.2% vs. 86.8%, P=0.001) in diabetic compared to non-diabetic individuals.
  • Follow-up averaged 16.2 months.

Impact:

  • Sirolimus-eluting stents (SES) demonstrate comparable long-term safety and efficacy to bare metal stents (BMS) in diabetic patients with coronary artery disease (CAD).
  • The findings suggest that SES implantation may be a beneficial strategy for reducing major adverse cardiac events (MACE) and the need for repeat interventions in diabetic patients undergoing PCI.
  • This research highlights the importance of stent selection in managing diabetic patients with CAD to optimize long-term cardiovascular outcomes.

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Complications of Diabetes Mellitus01:22

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,...
