Summary
The Aslanger pattern on ECG may indicate acute coronary occlusion, even without ST-elevation myocardial infarction criteria. Recognizing this pattern is crucial for timely treatment and improved outcomes in acute coronary syndrome.
Area of Science:
- Cardiology
- Emergency Medicine
- Diagnostic Electrocardiography
Background:
- ST-elevation criteria on electrocardiograms (ECG) can fail to identify many acute coronary occlusions.
- Delayed diagnosis and treatment of acute coronary occlusions lead to poorer patient prognosis.
Observation:
- The Aslanger pattern is a newly proposed ECG finding that suggests acute coronary occlusion.
- This pattern may be present even when standard ST-elevation myocardial infarction criteria are not met.
Findings:
- A case study highlights a patient with acute chest pain presenting with an Aslanger pattern on initial ECG.
- Misdiagnosis at primary care and emergency settings resulted in delayed optimal management for the patient.
Implications:
- Early recognition of the Aslanger pattern is vital for prompt decision-making in acute coronary syndrome.
- Identifying this pattern can facilitate timely revascularization, potentially improving patient outcomes.
- This case underscores the need to incorporate the Aslanger pattern into the diagnostic approach for acute chest pain.

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

01:30Acute Coronary Syndrome I: Introduction
81
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

44
Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...

Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...
