Summary
Spontaneous coronary artery dissection (SCAD) is an important cause of acute coronary syndrome, particularly in young women. This review summarizes current evidence on SCAD epidemiology, management, and outcomes.
Area of Science:
- Cardiology
- Vascular Medicine
Background:
- Spontaneous coronary artery dissection (SCAD) is an infrequent cause of acute coronary syndrome (ACS).
- SCAD is increasingly recognized as a differential diagnosis for ACS, especially in young women, postpartum, and those with fibromuscular dysplasia.
- Significant knowledge gaps exist regarding SCAD pathophysiology, risk factors, and management.
Purpose of the Study:
- To review and synthesize current scientific evidence on spontaneous coronary artery dissection.
- To summarize the epidemiology, management strategies, and patient outcomes associated with SCAD.
Main Methods:
- Literature review of current scientific evidence.
- Synthesis of data on SCAD epidemiology, clinical presentation, and diagnosis.
- Analysis of acute and long-term management approaches and outcomes.
Main Results:
- SCAD presents with clinical features similar to other causes of ACS.
- SCAD is a significant consideration in specific patient populations, including young women and those with arteriopathies.
- Evidence regarding optimal treatment and long-term prognosis is still evolving.
Conclusions:
- Spontaneous coronary artery dissection is an important, though often underdiagnosed, cause of acute coronary syndrome.
- Further research is needed to clarify SCAD pathophysiology, identify risk factors, and establish optimal management guidelines.
- Improved understanding and standardized approaches are crucial for better patient outcomes in SCAD.

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...

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...

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 (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

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...
