Insights

Spontaneous coronary artery dissection (SCAD) is a key cause of heart attacks in women. This review highlights SCAD in Asian women, emphasizing diverse presentations and diagnostic challenges.

Area of Science:

  • Cardiology
  • Vascular Biology
  • Medical Case Studies

Background:

  • Spontaneous Coronary Artery Dissection (SCAD) is an increasingly recognized cause of acute coronary syndrome (ACS), particularly in younger women without traditional cardiovascular risk factors.
  • SCAD research has been predominantly Western-centric, leading to potential under-diagnosis and under-representation in Asian populations.
  • Understanding SCAD's unique epidemiology and clinical manifestations in diverse ethnic groups is crucial for improving patient outcomes.

Observation:

  • This review presents two distinct cases of SCAD in Singaporean women of Malay and Chinese descent.
  • The cases illustrate that pregnancy-associated SCAD is not the sole or most frequent presentation.
  • SCAD presentations are heterogeneous, and associations with connective tissue disorders like fibromuscular dysplasia warrant attention.

Findings:

  • SCAD diagnosis remains challenging for many cardiologists, often requiring a high index of suspicion.
  • Coronary angiography interpretation and the utility of intracoronary imaging are critical for accurate SCAD diagnosis.
  • Effective management necessitates a multidisciplinary team approach and tailored recovery programs.

Implications:

  • Increased awareness and research into SCAD in Asian populations are essential for enhancing diagnostic accuracy and treatment strategies.
  • Developing specialized recovery programs incorporating support groups, allied health, and cardiac rehabilitation is vital for long-term patient well-being.
  • Addressing the diagnostic and management complexities of SCAD can improve outcomes for affected individuals, especially in under-represented demographics.

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...

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...

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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...

Coronary Artery Disease III: Clinical Manifestations

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...
