Summary
Spontaneous coronary artery dissection (SCAD) is a rare cause of heart attack, typically seen in women. This report details two asymptomatic SCAD cases discovered during routine preoperative assessments, highlighting unique diagnostic and management considerations.
Area of Science:
- Cardiology
- Vascular Biology
- Medical Diagnostics
Background:
- Spontaneous coronary artery dissection (SCAD) is an uncommon cause of myocardial ischemia, often presenting with acute symptoms like angina or myocardial infarction.
- SCAD disproportionately affects women and is linked to autoimmune and collagen vascular diseases.
- Clinical outcomes and treatment strategies for SCAD are contingent upon the initial presentation and the dissection's severity.
Observation:
- This article presents two cases of SCAD that were incidentally discovered during routine preoperative evaluations.
- Both patients were asymptomatic at the time of diagnosis, underscoring the potential for silent SCAD.
- The cases highlight the importance of considering SCAD even in the absence of typical ischemic symptoms.
Findings:
- Asymptomatic SCAD can be diagnosed through routine preoperative screening.
- The diagnostic pathway for SCAD may differ in asymptomatic individuals compared to those with acute presentations.
- Early detection of SCAD, even when asymptomatic, is crucial for appropriate management.
Implications:
- Routine preoperative evaluations may identify asymptomatic SCAD, enabling proactive management.
- Understanding SCAD in asymptomatic individuals can refine diagnostic protocols and risk stratification.
- Further research is needed to establish optimal long-term management strategies for incidentally detected SCAD.

01:19Acute 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...
01:30Acute 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...

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...

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...

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...

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...
