    Insights

    This case study highlights a 60-year-old woman experiencing acute myocardial infarction due to coronary artery aneurysms. Atherosclerosis was identified as the likely cause of these complex vascular conditions.

    Area of Science:

    • Cardiology
    • Vascular Medicine
    • Interventional Cardiology

    Background:

    • Coronary artery aneurysms are rare but can lead to serious complications.
    • Atherosclerosis is a common underlying cause of cardiovascular disease.

    Observation:

    • A 60-year-old woman presented with acute infero-posterior myocardial infarction.
    • Cine-coronary arteriogram revealed diffuse epicardial coronary artery dilatation with multiple fusiform and saccular aneurysms.
    • Ventriculography showed reduced ejection fraction (36%) and regional wall motion abnormalities.

    Findings:

    • The coronary aneurysms were attributed to atherosclerosis.
    • Coronary embolization was suggested as the cause of the acute myocardial infarction.
    • Poor distal coronary artery run-off was noted.

    Implications:

    • This case underscores the importance of considering coronary aneurysms in patients with myocardial infarction.
    • Early diagnosis and management of atherosclerosis are crucial to prevent such complications.
    • Further research into the mechanisms of aneurysm formation and embolization is warranted.

    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...
    Atherosclerosis I: Introduction01:30

    Atherosclerosis I: Introduction

    Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

    Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

    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)...
    Aneurysm I: Introduction01:30

    Aneurysm I: Introduction

    An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

    Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
