Background: Large scale randomized comparison of drug-eluting stents (DES) based on durable polymer (DP) versus biodegradable polymer (BP) technology is currently insufficient in patients with acute coronary syndrome (ACS). The present study sought to prove the non-inferiority of the DP-DES compared with the BP-DES in such patients. Methods: The HOST-REDUCE-POLYTECH-ACS trial is an investigator-initiated, randomized, open-label, adjudicator-blinded, multicenter, non-inferiority trial which compared the efficacy and safety of DP-DES and BP-DES in patients with ACS. The primary endpoint was patient oriented composite outcome (POCO, a composite of all-cause death, non-fatal myocardial infarction (MI), and any repeat revascularization) at 12 months. The key secondary endpoint was device oriented composite outcome (DOCO; a composite of cardiac death, target-vessel MI, or target lesion revascularization) at 12 months. Results: A total of 3413 patients were randomized to receive the DP-DES (1713 patients) and BP-DES (1700 patients). At 12 months, POCO occurred in 5.2% in the DP-DES group and 6.4% in the BP-DES group (Absolute risk difference: -1.2%, P non-inferiority <0.001). The key secondary endpoint, DOCO, occurred less frequently in the DP-DES group (DP-DES vs. BP-DES: 2.6% vs. 3.9%, HR 0.67, 95% CI 0.46-0.98, p=0.038), mostly due to a reduction in target lesion revascularization. The rate of spontaneous non-fatal MI and stent thrombosis were extremely low, with no significant difference between the 2 groups (0.6% vs. 0.8%; p=0.513 and 0.1% vs 0.4%; p=0.174, respectively). Conclusions: In ACS patients receiving percutaneous coronary intervention (PCI), DP-DES was non-inferior to BP-DES with regard to POCO at 12 months after index PCI.

Abstract Background The triglyceride-glucose (TyG) index is an alternative marker of insulin resistance (IR) and is closely associated with the prevalence and prognosis of atherosclerotic cardiovascular disease (ASCVD). However, the association between the TyG index and in-stent restenosis (ISR) after drug-eluting stent (DES) implantation in patients with acute coronary syndrome (ACS) remains unknown. Methods The present study retrospectively recruited patients who were admitted for ACS and underwent coronary angiography at 6 to 24 months after successful DES-based percutaneous coronary intervention (PCI). In addition, we calculated the TyG index with the following formula: Ln(fasting triglyceride [mg/dL] × fasting blood glucose [mg/dL]/2) and divided patients into 3 groups according to the tertile of the TyG index. Most importantly, multivariate logistic regression analysis models were also constructed to assess the association between the TyG index and DES-ISR in patients with ACS. Results A total of 1574 patients with ACS (58.4 ± 9.4 years, 77.4% male) were included in this study. At the median follow-up time of 12 (9–14) months, the prevalence of DES-ISR increased stepwise with the increasing tertile of the TyG index (11.6% vs 17.3% vs 19.4%, p = 0.002), and the TyG index was also higher in the ISR group than in the non-ISR group (9.00 ± 0.58 vs 8.84 ± 0.61, p < 0.001). In addition, the positive association between the TyG index and the prevalence of DES-ISR was also determined in the fully adjusted model (TyG, per 1-unit increase: OR 1.424, 95% CI 1.116 to 1.818, p = 0.005; tertile of TyG, the OR (95% CI) values for tertile 2 and tertile 3 were 1.454 (1.013 to 2.087) and 1.634 (1.125 to 2.374), respectively, with tertile 1 as a reference). The association was also reflected in most subgroups. Moreover, adding the TyG index to the predictive model for DES-ISR in patients with ACS could contribute to an increase in C-statistics (0.675 vs 0.659, p = 0.010), categorical net reclassification improvement (0.090, p < 0.001), and integrated discrimination improvement (0.004, p = 0.040). Conclusion An elevated TyG index was independently and positively associated with DES-ISR in patients with ACS who underwent PCI. However, the incremental predictive value of the TyG index for DES-ISR was slight. To further confirm our findings, future studies are needed.

Stent Diameter

Coronary bifurcations are prone to the development of atherosclerosis. They pose technical difficulties for angioplasty treatment and are a predictor of stent thrombosis and restenosis. Treatment of coronary bifurcations is still subject to debate, especially when the side branch (SB) is large, not easily accessible and narrowed by a long lesion. There is currently no indexed treatment for this type of lesion (Medina classification), as the strategy of provisional SB stenting with drug-eluting stents (DES) has proved to be equally efficient as the dualstent technique. Complex techniques are associated with poor outcome in certain lesion types, such as T-stenting when the angle between the two distal branches is small or the crush and culotte technique in the presence of an open angle. Provisional SB stenting may be used when primary dual stenting is required, with a low risk of failure provided that the following guidelines are implemented: stenting of the main branch through the protected SB with a stent diameter adapted to the distal main branch, immediate optimisation of the proximal stent segment (Finet’s law), guidewire exchange, kissing balloon inflation with non-compliant balloons selected according to the diameter of the distal branches and T-stenting of the SB before final kissing inflation.
