About the Lab
Professor Duck Kyu Cho's research lab specializes in interventional cardiology and antithrombotic therapy, with a primary focus on optimizing dual antiplatelet therapy (DAPT) duration following percutaneous coronary intervention (PCI). The lab investigates the safety and efficacy of short-duration DAPT followed by P2Y12 inhibitor monotherapy, particularly in complex PCI and acute coronary syndrome patients. Key studies include the SMART-CHOICE trial and related trials evaluating bleeding and ischemic outcomes using risk scores like PRECISE-DAPT. The lab aims to balance thrombotic protection with bleeding risk reduction through personalized antiplatelet strategies.

15Importance: Data on P2Y12 inhibitor monotherapy after short-duration dual antiplatelet therapy (DAPT) in patients undergoing percutaneous coronary intervention are limited. Objective: To determine whether P2Y12 inhibitor monotherapy after 3 months of DAPT is noninferior to 12 months of DAPT in patients undergoing PCI. Design, Setting, and Participants: The SMART-CHOICE trial was an open-label, noninferiority, randomized study that was conducted in 33 hospitals in Korea and included 2993 patients
ClinicalTrials.gov Identifier: NCT02494895.
BACKGROUND: Stopping aspirin within 1 month after implantation of a drug-eluting stent for ticagrelor monotherapy has not been exclusively evaluated for patients with acute coronary syndrome. The aim of this study was to investigate whether ticagrelor monotherapy after <1 month of dual antiplatelet therapy (DAPT) is noninferior to 12 months of ticagrelor-based DAPT for adverse cardiovascular and bleeding events in patients with acute coronary syndrome. METHODS: In this randomized, open-label,
Background: Although the current guidelines endorse the PRECISE-DAPT score (Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy) to inform clinical decisions regarding duration of DAPT in patients undergoing percutaneous coronary intervention, use of the PRECISE-DAPT score to guide duration of DAPT has not been properly validated by randomized trials focused on the population with acute coronary syndrome. This study aimed to evalua

BACKGROUND: It remains unclear whether P2Y12 monotherapy, especially clopidogrel, following short-duration dual antiplatelet therapy (DAPT) is associated with favorable outcomes in patients undergoing complex percutaneous coronary intervention (PCI). Therefore, this study analyzed the efficacy and safety of P2Y12 inhibitor monotherapy, mostly clopidogrel (78%), in complex PCI following short-term DAPT. METHODS: The post-hoc analysis of the SMART-CHOICE trial involving 2,993 patients included 498
Recent studies have indicated that distal radial access (DRA) is feasible in patients undergoing percutaneous coronary intervention (PCI). The present study aimed to compare DRA, proximal radial access (PRA), and femoral access (FA) in patients with ST-elevation myocardial infarction (STEMI) undergoing PCI. Data were analyzed for 109 patients with STEMI treated via primary PCI from March 2020 to May 2021. The success rate of DRA was 83.3% (35/42), including seven cases of failed puncture (punctu
In patients with CKD and AMI who underwent PCI with 2nd-generation DES implantation, the use of IVUS guidance was associated with a significant reduction in 3-year TLF and showed consistently favorable outcomes regardless of eGFR and ESRD.
Recently, the left distal radial approach (DRA) for percutaneous coronary intervention (PCI) has been shown to be a feasible option, but there are limited data regarding the feasibility of performing bifurcation PCI via the left DRA. Therefore, this study aimed to describe our experience with the contemporary left DRA to perform PCI of bifurcation lesions. Between December 2017 and December 2019, we identified 106 patients treated with bifurcation PCI via the left DRA. We evaluated the success r
Importance: Although P2Y12 inhibitor monotherapy after a minimum period of dual antiplatelet therapy (DAPT) is a well-known way to reduce the risk of bleeding after percutaneous coronary intervention (PCI), data comparing long-term clinical outcomes between P2Y12 inhibitor monotherapy and extended DAPT in patients undergoing PCI have been unavailable. Objective: To identify the long-term safety and efficacy of P2Y12 inhibitor monotherapy following 3 months of DAPT after PCI. Design, Setting, and
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. M
