Aspirin Monotherapy vs No Antiplatelet Therapy in Stable Patients With Coronary Stents Undergoing Low-to-Intermediate Risk Noncardiac Surgery.

Background: Current guidelines recommend the perioperative continuation of aspirin in patients with coronary drug-eluting stents (DES) undergoing noncardiac surgery. However, supporting evidence is limited.

Objectives: This study aimed to compare continuing aspirin monotherapy vs temporarily holding all antiplatelet therapy before noncardiac surgery in patients with previous DES implantation.

Ticagrelor monotherapy in ST-elevation myocardial infarction: An individual patient-level meta-analysis from TICO and T-PASS trials.

Background: Patients with ST-elevation myocardial infarction (STEMI) tend to be excluded or under-represented in randomized clinical trials evaluating the effects of potent P2Y12 inhibitor monotherapy after short-term dual antiplatelet therapy (DAPT).

Methods: Individual patient data were pooled from randomized clinical trials that included STEMI patients undergoing drug-eluting stent (DES) implantation and compared ticagrelor monotherapy after short-term (≤3 months) DAPT versus ticagrelor-based 12-month DAPT in terms of centrally adjudicated clinical outcomes. The co-primary outcomes were efficacy outcome (composite of all-cause death, myocardial infarction, or stroke) and safety outcome (Bleeding Academic Research Consortium type 3 or 5 bleeding) at 1 year.

Effect of rosuvastatin versus atorvastatin on new-onset diabetes mellitus in patients treated with high-intensity statin therapy for coronary artery disease: a post-hoc analysis from the LODESTAR randomized clinical trial.

Background: The impact of rosuvastatin versus atorvastatin on new-onset diabetes mellitus (NODM) among patients treated with high-intensity statin therapy for coronary artery disease (CAD) remains to be clarified. This study aimed to evaluate the risk of NODM in patients with CAD treated with rosuvastatin compared to atorvastatin in the randomized LODESTAR trial.

Methods: In the LODESTAR trial, patients with CAD were randomly assigned to receive either rosuvastatin or atorvastatin using a 2-by-2 factorial randomization.

Long-term outcomes of percutaneous transluminal renal artery intervention: a retrospective study at a single center.

Background: The indications, benefits, and outcomes of percutaneous transluminal renal artery intervention (PTRI) remain controversial. The study purpose was to evaluate the long-term outcomes of PTRI in clinical practice.

Methods: A retrospective review of 217 subjects (254 renal arteries; mean age, 59.

Development of Clinically Validated Artificial Intelligence Model for Detecting ST-segment Elevation Myocardial Infarction.

Study Objective: Although the importance of primary percutaneous coronary intervention has been emphasized for ST-segment elevation myocardial infarction (STEMI), the appropriateness of the cardiac catheterization laboratory activation remains suboptimal. This study aimed to develop a precise artificial intelligence (AI) model for the diagnosis of STEMI and accurate cardiac catheterization laboratory activation.

Methods: We used electrocardiography (ECG) waveform data from a prospective percutaneous coronary intervention registry in Korea in this study.

Treat-to-target or high-intensity statin treatment in older adults with coronary artery disease: a post hoc analysis of the LODESTAR trial.

Background: The optimal statin treatment strategy that is balanced for both efficacy and safety has not been clearly determined in older adults with coronary artery disease (CAD).

Methods: In the post hoc analysis of the LODESTAR (low-density lipoprotein cholesterol-targeting statin therapy versus intensity-based statin therapy in patients with coronary artery disease) trial, the impact between a treat-to-target strategy versus a high-intensity statin therapy strategy was compared in older adults (aged 75 years or older). The goal of treat-to-target low-density lipoprotein cholesterol (LDL-C) level was 50-70 mg/dl.

Development of a machine vision-based weight prediction system of butterhead lettuce ( L.) using deep learning models for industrial plant factory.

Introduction: Indoor agriculture, especially plant factories, becomes essential because of the advantages of cultivating crops yearly to address global food shortages. Plant factories have been growing in scale as commercialized. Developing an on-site system that estimates the fresh weight of crops non-destructively for decision-making on harvest time is necessary to maximize yield and profits.

Clinical Outcomes After Drug-Coated Balloon Treatment in Popliteal Artery Disease: K-POP Registry 12-Month Results.

Background And Objectives: The popliteal artery is generally regarded as a "no-stent zone." Limited data are available on the outcomes of drug-coated balloons (DCBs) for popliteal artery disease. This study aimed to evaluate the 12-month clinical outcomes among patients who received DCB treatment for atherosclerotic popliteal artery disease.

Ticagrelor monotherapy for acute coronary syndrome: an individual patient data meta-analysis of TICO and T-PASS trials.

Background And Aims: In patients with acute coronary syndrome (ACS), dual antiplatelet therapy (DAPT) with aspirin and a potent P2Y12 inhibitor is recommended for 12 months after drug-eluting stent (DES) implantation. Monotherapy with a potent P2Y12 inhibitor after short-term DAPT is an attractive option to better balance the risks of ischaemia and bleeding. Therefore, this study evaluated the efficacy and safety of ticagrelor monotherapy after short-term DAPT, especially in patients with ACS.

Intravascular ultrasound-guided versus angiography-guided percutaneous coronary intervention for acute myocardial infarction with cardiogenic shock.

The benefits of intravascular ultrasonography (IVUS)-guided percutaneous coronary intervention (PCI) in the clinical context of cardiogenic shock (CS) complicating acute myocardial infarction are lacking. We aimed to investigate the impact of IVUS-guided PCI in patients with AMI and CS. From the pooled data based on a series of Korean AMI registries during 2011-2020, we identified 1418 consecutive patients who underwent PCI with second generation drug-eluting stent (DES) for AMI and CS.
