Acute ST-segment elevation myocardial infarction (STEMI) occurs due to occlusion of one or more coronary arteries causing myocardial injury. It is a medical emergency and requires prompt diagnosis and intervention. Transient ST-segment elevation can occur due to coronary vasospasm, and their association has been reported with subarachnoid hemorrhage. We present a distinct case of ST-segment elevations in inferior leads with reciprocal ST-depressions in lateral leads, indicating STEMI that leads to complete heart block and ventricular fibrillation cardiac arrest in a patient with subarachnoid hemorrhage. The coronary angiogram was negative for any obstructive coronary artery disease.

Objective: To describe the characteristics of patients diagnosed with acute heart failure (AHF) in emergency departments (EDs) who develop cardiogenic shock (CS) not associated with ST-segment elevation acute coronary syndrome (STACS).
Methods: Information for patients diagnosed with AHF in 23 Spanish EDs and registered between 2009 and 2019 were included for analysis if the patients developed symptoms consistent with CS. We described baseline clinical characteristics related to cardiac decompensation and CS, as well as 30-day mortality.

This study aimed to investigate the relationship between the restoration of coronary flow just before stent deployment and the final thrombolysis in myocardial infarction (TIMI) flow grade 3 in patients with ST-segment elevation myocardial infarction (STEMI) whose initial TIMI flow grade ≤ 1. In primary percutaneous coronary intervention (PCI), initial TMI flow grade ≤ 1 is closely associated with suboptimal final TIMI flow grade. We included 466 STEMI patients with initial TIMI flow grade ≤ 1 and divided into a restored flow group or an unrestored flow group according to the TIMI flow grade just before stent deployment.

In ACS patients presenting with no-ST-segment elevation (NSTE-ACS), the timing of symptom onset pre-hospital may inform the disease stage and prognosis. We pilot-tested two off-the-shelf natural language processing (NLP) pipelines, namely and ( ), to extract date and time (DateTime) information of patient-reported chest pain symptoms from electronic health records (EHR) clinical notes.

Background: In-hospital mortality risk prediction is an important tool for benchmarking quality and patient prognostication. Given changes in patient characteristics and treatments over time, a contemporary risk model for patients with acute myocardial infarction (MI) is needed.
Methods: Data from 313 825 acute MI hospitalizations between January 2019 and December 2020 for adults aged ≥18 years at 784 sites in the National Cardiovascular Data Registry Chest Pain-MI Registry were used to develop a risk-standardized model to predict in-hospital mortality.
