Insights

ST elevation myocardial infarction (STEMI) typically indicates blocked arteries. However, some STEMI patients have MINOCA (myocardial infarction with non-obstructive coronary arteries), requiring specific diagnosis and treatment.

Area of Science:

  • Cardiology
  • Internal Medicine
  • Diagnostic Imaging

Background:

  • ST elevation myocardial infarction (STEMI) is commonly associated with obstructive coronary artery disease.
  • A subset of STEMI patients present with minimal or no coronary blockage on angiography, a condition known as myocardial infarction with non-obstructive coronary arteries (MINOCA).

Observation:

  • This case report details a unique presentation of MINOCA in a patient initially diagnosed with STEMI.
  • The diagnostic challenge lies in MINOCA's heterogeneous etiology, necessitating a targeted workup.

Findings:

  • MINOCA represents a distinct clinical entity within the spectrum of acute coronary syndromes.
  • Identifying the underlying cause of MINOCA is crucial for effective management.

Implications:

  • Prompt and accurate diagnosis of MINOCA is essential for appropriate treatment selection.
  • Effective MINOCA management aims to reduce mortality rates comparable to obstructive coronary disease.
  • This case highlights the importance of considering MINOCA in STEMI presentations without obstructive disease.

Acute Coronary Syndrome I: Introduction01:30

Acute Coronary Syndrome I: Introduction

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...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

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...

Angina II: Classification

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...

Acute Coronary Syndrome III: Diagnostic Studies

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...

Angina III: Clinical Manifestations and Assessment01:29

Angina III: Clinical Manifestations and Assessment

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...
