Emergency department (ED) management of patients who present with suspected unstable angina (UA) and non-ST elevation myocardial infarction (NSTEMI) is especially challenging. Therapies that demonstrate benefit in patients who experience proven disease may not be indicated in patients who present with suspected disease. The emergency practitioner must have a clear understanding of the benefit and harm of each therapy, allowing formulation of a simple approach to treatment selection based on disease presentation. This article reviews current literature and discusses the treatment recommendations from the American College of Cardiology (ACC) and American Heart Association (AHA) for patients who experience UA and ST elevation myocardial infarction (STEMI).

Institute of Nephrology, Zhongda Hospital, Southeast University School of Medicine, Nanjing, Jiangsu, 210009, People's Republic of China.
Objective: This study evaluated the diagnostic value of plasma Neutrophil extracellular traps (NETs) levels and the index of cardiac electrophysiological balance (iCEB) in identifying silent myocardial ischemia (SMI) in maintenance hemodialysis (MHD) patients.
Methods: This cross-sectional observational study involved patients receiving MHD treatment. Data were collected on coronary angiography performed in our hospital from February 2023 to February 2024.

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.
Dynamics of HDL-Cholesterol Following a Post-Myocardial Infarction Cardiac Rehabilitation Program.

Background: Exercise-based cardiac rehabilitation programs (CRP) are recommended for patients following acute coronary syndrome to potentially improve high-density lipoprotein cholesterol (HDL-C) levels and prognosis. However, not all patients reach target HDL-C levels. Here we analyze the dynamics and predictors of HDL-C increase during CRP in patients following ST-segment elevation myocardial infarction or occlusion myocardial infarction.

Background: To explore the association between gamma-glutamyltransferase (GGT) and in-hospital heart failure (HF) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).
Methods: A total of 412 patients diagnosed with STEMI and treated with primary PCI were included in our study. Univariate and multivariate logistic regression models were used to evaluate the association between GGT and the risk of in-hospital HF in STEMI patients.

is a gram-positive bacterium commonly found in dairy products and used as a probiotic due to its resistance to acid and bile. While generally considered safe, rare cases of bacteremia and endocarditis have been reported, primarily in individuals with significant risk factors. This report discusses an elderly male with a history of cardiovascular diseases, diabetes, and asthma, who developed bacteremia and endocarditis after consuming large quantities of Greek yogurt.
