Background Premature discontinuation of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention is related to higher short‐term risks of adverse outcomes. Whether these risks persist in the long‐term is uncertain. Methods and Results We assessed all patients having percutaneous coronary intervention with coronary second‐ or first‐generation drug‐eluting stents in the Veterans Affairs healthcare system between 2006 and 2012 who were free of major ischemic or bleeding events in the first 12 months. The characteristics of patients who stopped DAPT prematurely (1–9 months duration), compared with >9 to 12 months, or extended duration (>12 months) were assessed by odds ratios (ORs) from multivariable logistic models. The risk of adverse clinical outcomes over a mean 5.1 years in patients who stopped DAPT prematurely was assessed by hazard ratios (HRs) and 95% CIs from Cox regression models. A total of 14 239 had second‐generation drug‐eluting stents, and 8583 had first‐generation drug‐eluting stents. Premature discontinuation of DAPT was more likely in Black patients (OR, 1.54; 95% CI, 1.40–1.68), patients with greater frailty (OR, 1.04; 95% CI, 1.03–1.05), and patients with higher low‐density lipoprotein cholesterol, and less likely in patients on statins (OR, 0.87; 95% CI, 0.80–0.95). Patients who stopped DAPT prematurely had higher long‐term risks of death (second‐generation drug‐eluting stents: HR, 1.35; 95% CI, 1.19–1.56), myocardial infarction (second‐generation drug‐eluting stents: HR, 1.46; 95% CI, 1.22–1.74), and repeated coronary revascularization (second‐generation drug‐eluting stents: HR, 1.24; 95% CI, 1.08–1.41). Conclusions Patients who stop DAPT prematurely have features that reflect greater frailty, poorer medication use, and other social factors. They continue to have higher risks of major adverse outcomes over the long‐term and may require more intensive surveillance many years after percutaneous coronary intervention.

Background: The following registry (Katowice-Zabrze retrospective registry) aimed to assess the influence of a chronic kidney disease (CKD) on long-term clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) using either first-generation (DES-I) or second-generation (DES-II) drug-eluting stents. Methods: The study group consisted of 1,908 consecutive patients, of whom 331 (17.3%) had CKD. CKD was defined as an estimated glomerular filtration rate of <60 mL/min/m2. We evaluated the major adverse cardiac and cerebral events (MACCE), i.e., the composite of death, myocardial infarction (MI), stroke, and target vessel revascularization at the 12-month follow-up. Results: CKD patients had a lower left ventricular ejection fraction and more often a history of MI and PCI. Coronary angiography revealed that multivessel coronary artery disease, intracoronary thrombus, and extensive calcifications were more frequent in patients with CKD. However, the SYNTAX score did not vary between patients with or without CKD. There was a higher rate of in-hospital bleedings requiring blood transfusion in patients with CKD. At the 1-year follow-up, MACCE (17.8 vs. 12.6%, HR = 1.46 [95% CI 1.05-2.03], p = 0.009) and death (8.4 vs. 2.3%, HR = 3.9 [95% CI 2.0-7.5], p < 0.001) were more often observed in CKD patients. Multivariable Cox analysis revealed that CKD was an independent risk predictor of death after PCI at the 1-year follow-up (HR = 2.1 [95% CI 1.2-3.6], p = 0.004). In comparison to DES-I, the use of DES-II did not decrease the adverse effect of CKD on MACCE. Conclusion: CKD patients had an increased risk of in-hospital bleeding requiring blood transfusion and a higher risk of MACCE and death at the 12-month follow-up. The use of second-generation DES did not improve clinical outcomes in patients with CKD at the 12-month follow-up.

Background and Objectives: The second-generation drug-eluting stents have been used to treat chronic total occlusion lesion. However, there is limited evidence of the clinical outcomes that whether the second-generation drug-eluting stents is superior to first-generation ones in patients with chronic total occlusion lesion undergoing percutaneous coronary intervention. The study aimed to compare the differences in clinical outcomes between the two generations drug-eluting stents in patients with those by a meta-analysis.Methods: PubMed, Embase, the Cochrane library and Web of science databases were systemically searched before March, 2021. Randomized controlled trials and observational studies were included to compare the second-generation drug-eluting stents with the first-generation ones in patients with chronic total occlusion lesion undergoing percutaneous coronary intervention. The clinical outcomes were major adverse cardiac events (MACE), target vessel revascularization, myocardial infarction, all-cause death. Fixed effects models were used to calculate the odds ratio (OR) and 95% confidence interval (CI) of each clinical outcome. Sensitivity analysis was performed to detect potential sources of heterogeneity. Subgroup analyses were used to assess the differential effects.Results: The meta-analysis included eight studies involving 4,583 patients with chronic total occlusion lesion undergoing percutaneous coronary intervention. Pooled analysis showed that the incidence of MACE (OR = 0.68, 95%CI 0.54–0.85, P = 0.0008), target vessel revascularization (OR = 0.70, 95%CI 0.54–0.91, P = 0.007), and myocardial infarction (OR = 0.58, 95%CI 0.37–0.93, P = 0.02) were lower in the second-generation drug-eluting stents compared with the first-generation ones. However, there was not difference in all-cause deaths between two drug-eluting stents (OR = 0.67, 95%CI 0.45–1.01, P = 0.05).Conclusions: The second-generation drug-eluting stents are associated with lower MACE, target vessel revascularization, and myocardial infarction compared with the first-generation ones in patients with chronic total occlusion lesion undergoing percutaneous coronary intervention. The results of this study can provide a reference for the selection of stents in patients with chronic total occlusion lesion. Further randomized controlled trials are needed to verify that the second-generation drug-eluting stents is superior to the first-generation ones in patients with chronic total occlusion (Registered by PROSPERO, CRD42020158406).
