Abstract
- Introduction: Despite the increasing number of complex percutaneous coronary interventions (CPCI), data regarding outcomes following CPCI in patients with diabetes mellitus (DM) are scarce. Hypothesis: Compared to the general population, diabetic patients undergoing CPCI have worse prognosis. Methods: We analyzed data of patients who underwent PCI in a tertiary-care center between 2009 and 2017. Patients were divided into 2 groups (CPCI and non-CPCI) stratified by presence of DM. CPCI was defined as having ≥1 of the following: stent length >60 mm, ≥3 stents implanted, ≥3 lesions, ≥3 target vessels, bifurcation with ≥2 stents, or chronic total occlusion. The main outcome was major adverse cardiac events (MACE), a composite of death, myocardial infarction (MI) and target vessel revascularization (TVR) at 1 year. Results: Out of 20,412 patients included, 5,038 (24.7%) underwent CPCI. Patients with DM constituted 46.5% (n=9,494) of the overall cohort and 44.5% (n=2,240) of CPCI group. Among patients undergoing CPCI, diabetics were younger, more likely to be female, and had more cardiovascular risk factors (kidney disease, dyslipidemia, and hypertension) than non-diabetics. In addition, diabetic patients had more advanced coronary disease (multivessel disease, high syntax score, and longer lesion length). At 1 year, diabetic patients had higher risk of MACE than non-diabetic, regardless of PCI complexity ( Figure 1 ). Nonetheless, there was a significant interaction between CPCI and diabetes in terms of mortality at 1 year (p-interaction=0.009). In contrast, compared to non-diabetics, a higher risk of TVR ( adj HR 1.49, 95% CI [1.24 - 1.78], p adj HR 1.45, 95% CI [1.05 - 1.98], p=0.02) was observed in diabetics undergoing non-CPCI but not CPCI. Conclusion: Diabetic patients are at higher risk of MACE than the general population regardless of PCI complexity. Yet, 1-year mortality is substantially higher in diabetics undergoing CPCI than non-CPCI.
