We present a case of effective late reperfusion for atrio-ventricular conduction recovery in a patient with recent myocardial infarction complicated by advanced atrio-ventricular block (AVB). A 50-year-old Japanese man was transferred to our hospital with a recent diagnosis of myocardial infarction 44 h after onset. We performed emergent coronary angiography on Day 5 because he developed bradycardia with two to one advanced AVB resistant to atropine without chest pain or ST-T changes. Coronary angiography showed the right coronary artery (RCA) with total proximal occlusion. Emergent percutaneous coronary intervention (PCI) was performed to the RCA. Just after PCI, the PR interval was shortened to 0.25 s. Moreover, the PR interval was shortened to 0.18 s at Day 16. This report shows the new finding that delayed PCI may be effective in patients with recent myocardial infarction complicated by new AVB outside of the usual therapeutic window of 12 h.

Background: A significant number of patients with atrial fibrillation (AF) on direct oral anticoagulants (DOACs) receives off-label or inappropriate doses. This study examines the prevalence, dosages, and clinical outcomes in AF-patients on DOAC therapy admitted to an emergency department (ED).
Methods: This retrospective single-center observational study utilized data from the Heidelberg Registry of Atrial Fibrillation (HERA-FIB), consecutively including patients with AF presenting to the ED of the University Hospital of Heidelberg from June 2009 to March 2020.

Background: Thrombolysis in Myocardial Infarction (TIMI) risk score in patients with ST-segment elevation myocardial infarction (STEMI) is associated with major adverse cardiovascular events (MACE). This study aimed to develop a prediction model based on the TIMI risk score for MACE in STEMI patients after percutaneous coronary intervention (PCI).
Methods: We conducted a retrospective data analysis on 290 acute STEMI patients admitted to the Affiliated Hospital of Yangzhou University from January 2022 to June 2023 and met the inclusion criteria.

Kounis syndrome also known as allergic myocardial infarction, represents the simultaneous occurrence of acute coronary syndromes with allergic or hypersensitivity reactions. We present a case of a 58-years-old male who developed anaphylaxis following a leech bite, leading to myocardial infarction despite the absence of prior allergic history. He was entubated and cardiopulmonary resusciation had been performed for 10 minutes.

Myocardial infarction (MI) is a leading cause of morbidity and mortality worldwide, and mitigating oxidative stress is crucial in managing MI. Nuclear factor erythroid 2-related factor 2 (Nrf2) plays a critical role in combating oxidative stress and facilitating cardiac remodeling post-MI. Here, we engineered Cerium oxide (CeO) nanoparticle-guided assemblies of ceria/Nrf2 nanocomposites to deliver Nrf2 plasmids.
