Background: Studies comparing the clinical outcomes of second-generation biodegradable polymer drug-eluting stents (BP-DES) and second-generation durable polymer drug-eluting stents (DP-DES) in patients with ST-segment elevation myocardial infarction (STEMI) with follow-up duration of more than 1 year are still limited.
Objective: This study aimed to compare the 2-year clinical outcome of BP-DES with second-generation DP-DES in patients undergoing primary percutaneous coronary intervention (PPCI).
Methods: This is a retrospective cohort study in patients with STEMI, the primary endpoint was major adverse cardiac events (MACE) defined as recurrent myocardial infarction, total repeat revascularisation and cardiac death. The secondary endpoint was stent thrombosis (ST) defined as definite, probable or possible.
Results: A total of 400 patients were analysed (197 BP-DES groups and 203 DP-DES groups). BP-DES were independently associated with lower incidence of MACE (adjusted HR 0.67, 95% CI 0.21 to 0.91, p=0.005) and ST (adjusted HR 0.62, 95% CI 0.19 to 0.73, p<0.016) within 2 years of follow-up. Subgroup analysis of MACE individual components showed that BP-DES were associated with lower cardiac deaths (HR 0.35; 95% CI 0.18 to 0.94; p<0.001) compared to DP-DES, but not recurrent myocardial infarction and total repeat revascularisation.
Conclusions: BP-DES were associated with better clinical outcomes compared to second-generation DP-DES in patients with STEMI undergoing PPCI.

In clinical practice, the impact of procedural or patient-related risk factors on 1-year clinical outcomes in patients receiving 1-month of dual antiplatelet therapy (DAPT) followed by P2Y12 inhibitor monotherapy after contemporary percutaneous coronary intervention (PCI) remains unclear. Using data from the multi-center REIWA registry which included patients treated with thin-strut biodegradable polymer drug-eluting stent (BP-DES) and 1-month DAPT followed by P2Y12 inhibitor monotherapy, we assessed the primary endpoint (a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, ischemic or hemorrhagic stroke, and major or minor bleeding) in patients with and without procedural (treatment of three vessels, three or more lesions, three or more stents, bifurcation with two stents, long stenting, and target of chronic total occlusion) and patient-related risk factor (renal insufficiency, anemia, peripheral vascular disease, prior or current history of heart failure and advanced age of ≥ 75 years). Among the 1,202 patients who underwent complete revascularization by PCI, 276 (23.

Background: First-generation bioresorbable scaffolds (BRS) increased risks of stent thrombosis and adverse events. The Bioheart scaffold is a new poly-L-lactic acid-based BRS.
Objectives: This study sought to evaluate the efficacy and safety of the BRS in patients with coronary artery disease.

Background: The risk-benefit ratio of the Absorb bioresorbable vascular scaffold (BVS) may vary before and after 3 years, the time point of complete bioresorption of the poly-L-lactic acid scaffold.
Objectives: The aim of this study was to determine the time-varying outcomes of the Absorb BVS compared with cobalt-chromium everolimus-eluting stents (EES) from a large individual-patient-data pooled analysis of randomized trials.
Methods: The individual patient data from 5 trials that randomized 5,988 patients undergoing percutaneous coronary intervention to the Absorb BVS vs EES with 5-year follow-up were pooled.

Background: Few data are available on polymer-free drug-eluting stents in patients undergoing percutaneous coronary intervention (PCI).
Aims: We aimed to determine the efficacy and safety of a polymer-free amphilimus-eluting stent (AES), using a reservoir-based technology for drug delivery, compared with a biodegradable-polymer everolimus-eluting stent (EES).
Methods: This was a randomised, investigator-initiated, assessor-blind, non-inferiority trial conducted at 14 hospitals in Italy (ClinicalTrials.

Background/objectives: The purpose of this study was to develop the gemcitabine-loaded drug-eluting beads (G-DEBs) for transarterial chemoembolization (TACE) in rabbit renal tumors and to evaluate their antitumor effect using 2-deoxy-2-[(18)F]fluoro-D-glucose positron emission tomography/X-ray computed tomography (F-FDG PET/CT).
Methods: DEBs were prepared by polyvinyl alcohol-based macromer crosslinked with -acryl tyrosine and ,'-methylenebis(acrylamide). Gemcitabine was loaded through ion change to obtain G-DEBs.
