Background: The optimal timing of complete revascularisation for patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease remains unclear. We aimed to assess whether immediate complete revascularisation was non-inferior to staged complete revascularisation during the index admission.
Methods: We conducted an open-label, randomised, non-inferiority trial at 14 hospitals in South Korea.
Background: Fractional flow reserve (FFR)-guided or angiography-guided complete revascularization has not been evaluated in patients with acute myocardial infarction (AMI) with multivessel disease and reduced left ventricular ejection fraction (LVEF). This study sought to evaluate the impact of FFR-guided percutaneous coronary intervention (PCI) for patients with AMI with multivessel disease according to left ventricular systolic function.
Methods: We performed a prespecified analysis of the FRAME-AMI (Fractional Flow Reserve Versus Angiography-Guided Strategy in Acute Myocardial Infarction With Multivessel Disease) trial, which randomly allocated 562 patients to undergo either FFR-guided PCI (FFR ≤0.
Chlorogenic acid, an ester of caffeic acid and quinic acid, is found in foods such as eggplant and peaches. Its role in heart disease remains poorly understood. This study investigated whether chlorogenic acid affects cardiac hypertrophy and fibrosis in animal and cellular models of isoproterenol-induced cardiac hypertrophy.

Aims: Rapid myocardial revascularization in patients with acute myocardial infarction (AMI) is essential to improve clinical outcomes. There is still room for improvement in the timely diagnosis of AMI. This study aimed to develop an artificial intelligence (AI) model using electrocardiograms (ECGs) for detecting AMI needing revascularization.

Background: Despite advancements in percutaneous coronary intervention (PCI), stent-related complications continue to occur, emphasizing the necessity for stent optimization. This study employed optical coherence tomography (OCT) to investigate the safety and efficacy of overexpanding the biodegradable polymer everolimus-eluting stent (SYNERGY; Boston Scientific, Marlborough, Massachusetts, USA) stent in large coronary arteries.
Methods: This single-center observational study enrolled patients with ischemic heart disease requiring stent placement in large coronary arteries (≥4.
Introduction: The simultaneous occurrence of acute myocardial infarction (AMI) and venous thromboembolism (VTE) is rare and often associated with underlying malignancies. This study reports a rare case of concurrent AMI and pulmonary thromboembolism in a patient diagnosed with pancreatic cancer.
Case Presentation: A 70-year-old woman presented with acute chest pain and ST-segment elevation myocardial infarction, prompting immediate percutaneous coronary intervention (PCI) with the deployment of a drug-eluting stent.
Heart failure (HF) remains a major cause of mortality worldwide. While novel approaches, including gene and cell therapies, show promise, efficient delivery methods for such biologics to the heart are critically needed. One emerging strategy is lung-to-heart delivery using nanoparticle (NP)-encapsulated biologics.

This study compared long-term outcomes of complete (CR) and incomplete revascularization (IR) in patients with estimated glomerular filtration rate (eGFR) ≥60 or <60 mL/min/1.73 m METHODS: Using data from the Korea Acute Myocardial Infarction Registry-National Institute of Health, 5962 patients (mean age: 65.

Therefore, this study aimed to compare the clinical outcomes of high- and moderate-intensity statin therapy in this population.
Methods: A total of 752 participants with AMI and LDL-C levels < 55 mg/dL from a Korean nationwide multicenter observational cohort (2016-2020) were included and categorized into two groups: high-intensity statin group (n = 384) and moderate-intensity statin group (n = 368).
Background And Objectives: Cigarette smoking is a major risk factor for atherosclerosis. Nicotine, a crucial constituent of tobacco, contributes to atherosclerosis development and progression. However, evidence of the association between nicotine and neointima formation is limited.

A total of 386 NSTEMI patients with severe LV dysfunction from the nationwide, multicenter, and prospective Korea Acute Myocardial Infarction Registry V (KAMIR-V) were enrolled. Severe LV dysfunction was defined as LV ejection fraction ≤ 35%.

Background: A drug-eluting stent (DES) is a highly beneficial medical device used to widen or unblock narrowed blood vessels. However, the drugs released by the implantation of DES may hinder the re-endothelialization process, increasing the risk of late thrombosis. We have developed a tacrolimus-eluting stent (TES) that as acts as a potent antiproliferative and immunosuppressive agent, enhancing endothelial regeneration.

This study aimed to comparatively assess the ischaemic and bleeding outcomes of adjusted-dose (maintenance dose: 3.75 mg) and standard-dose (maintenance dose: 10 mg) prasugrel in East Asian patients with AMI undergoing PCI.

Objectives: This study investigated the optimal timing for percutaneous coronary intervention (PCI) in patients with NSTEMI complicated by heart failure (HF).
Methods: In total, 762 patients with NSTEMI and HF in a multicenter, prospective registry in South Korea were classified according to the Killip classification (Killip class 2, n = 414 and Killip class 3, n = 348) and underwent early (within 24 h) and delayed (after 24 h) PCI. The primary outcome was all-cause mortality which was further analyzed with landmark analysis with two months as a cut-off.
There are limited data on outcomes after implantation of everolimus-eluting stents (EES) in East Asian patients with small vessel coronary lesions. A total of 1,600 patients treated with XIENCE EES (Abbott Vascular, CA, USA) were divided into the small vessel group treated with one ≤2.5 mm stent (n=119) and the non-small vessel group treated with one ≥2.

Background/aims: Due to limited real-world evidence on the association between time to presentation (T2P) and outcomes following acute myocardial infarction and diabetes (AMI-DM), we investigated the characteristics of patients with AMI-DM and their outcomes based on their T2P.
Methods: 4,455 patients with AMI-DM from a Korean nationwide observational cohort (2011-2015) were divided into early and late presenters according to symptom-to-door time. The effects of T2P on three-year all-cause mortality were estimated using inverse probability of treatment weighting (IPTW) and survival analysis.
