Background: Obtaining an electrocardiogram (ECG) is the gold standard for initial diagnostics of atraumatic chest pain. To provide optimal patient care, the treating physician has to be proficient in recognizing early signs of myocardial ischemia. Information from the clinical assessment and typical ECG signs have to be recognized promptly in order to diagnose myocardial ischemia early.
Methods: A selective literature search in international databases (PubMed, Cochrane Library, Google Scholar) was conducted; current, topic-specific websites and literature were also included and evaluated.
Results: Several subtle ECG abnormalities exist besides the typical ST-elevation myocardial infarction (STEMI) and well-known STEMI equivalents and may point to possible myocardial ischemia.
Discussion: To fully evaluate the ECG in patients with atraumatic chest pain, typical signs of ischemia like STEMI as well as subtle ECG signs should be recognized to allow early cardiac intervention.

Introduction: The use of weight loss supplements is increasing, often driven by online marketing. However, many of these supplements are adulterated with undeclared pharmaceutical substances, potentially posing significant health risks. We investigated the presence of sibutramine and sildenafil in weight loss supplements and assessed the associated clinical outcomes.

Background: The circadian rhythm of myocardial infarction (MI) in patients with obstructive sleep apnea (OSA) remains disputable and no studies have directly evaluated the relationship between nocturnal hypoxemia and the circadian rhythm of MI. The aim of the current study was to evaluate the association of OSA and nocturnal hypoxemia with MI onset during the night.
Methods: Patients with MI in the OSA-acute coronary syndrome (ACS) project (NCT03362385) were recruited.
Corkscrew esophagus in an elderly patient: A case of diffuse esophageal spasm with literature review.

Diffuse esophageal spasm (DES) is a rare motility disorder characterized by uncoordinated esophageal contractions, often presenting with dysphagia and chest pain. This case describes a 70-year-old male who presented with atypical symptoms of DES, including episodic dysphagia to solids, postprandial vomiting, and chest pain triggered by cold liquids. Initially misdiagnosed as indigestion, further evaluation with barium swallow imaging revealed a "corkscrew" esophagus, leading to the diagnosis of DES.

Infective endocarditis used to frequently cause mortality in subjects having PDA before the advent of antibiotics and surgical ligation. It has been documented that clinically silent PDAs may cause infective complications of heart valves. We present case of an 18-years-old male who presented with palpitations and fever to our emergency department.

Most patients are eventually admitted to the hospital to "rule out ACS" even when there are no significant EKG abnormalities or elevated cardiac enzymes. In addition to undergoing expensive tests while in the hospital, patients are also exposed to iatrogenic harm thereby worsening the overall healthcare costs.
