Summary
Spontaneous coronary artery dissection (SCAD) is a rare cause of heart attack, often diagnosed late. This study highlights successful surgical treatment for SCAD in two patients, emphasizing timely intervention.
Area of Science:
- Cardiology
- Vascular Surgery
- Pathology
Background:
- Spontaneous coronary artery dissection (SCAD) is an uncommon yet critical cause of acute coronary syndrome (ACS).
- SCAD diagnosis is frequently delayed, often occurring post-mortem.
- Key risk factors include the peripartum state, oral contraceptive use, and underlying atherosclerotic disease.
Observation:
- SCAD should be suspected in young, healthy individuals presenting with acute myocardial ischemic syndrome.
- Prompt diagnosis and intervention are crucial due to the risk of sudden cardiac death associated with SCAD.
- This report details two cases of SCAD in patients presenting with acute ischemic symptoms.
Findings:
- Both SCAD cases were successfully managed with emergency coronary artery bypass grafting (CABG).
- The first case utilized both left internal mammary artery (LIMA) and radial artery grafts.
- The second case involved LIMA grafting exclusively.
Implications:
- Emergency CABG is a viable and effective treatment strategy for SCAD.
- Successful surgical revascularization can prevent adverse outcomes in SCAD patients.
- Increased clinical awareness and timely diagnosis are essential for improving SCAD patient management.

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...
01:26Coronary Artery Disease II: Pathophysiology
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) 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...

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...
