Summary
Myocardial bridges (MBs) can cause acute coronary syndromes in low-risk patients by promoting atherosclerotic plaque rupture. Investigating MBs is crucial for understanding and managing these events.
Area of Science:
- Cardiology
- Vascular Biology
Background:
- Myocardial bridges (MBs) are common coronary artery anomalies.
- MBs are associated with proximal atherosclerotic lesions.
- These lesions may predispose patients to acute coronary events, even in low-risk individuals.
Purpose of the Study:
- To investigate the role of myocardial bridges in acute coronary syndromes.
- To explore the mechanism of plaque rupture in patients with MBs and low cardiovascular risk.
Main Methods:
- Case report of 2 patients with MBs presenting with acute coronary syndromes.
- Utilized coronary angiography and intravascular ultrasound for detailed study.
- Confirmed atherosclerotic plaque rupture proximal to the MB.
Main Results:
- Identified myocardial bridges as a potential cause of acute coronary syndromes in low-risk patients.
- Intravascular ultrasound confirmed plaque rupture proximal to the MB in both cases.
- Highlighted the prognostic implications of MBs in acute coronary events.
Conclusions:
- Myocardial bridges may act as an underlying cause of ruptured plaques in unexplained acute coronary syndromes.
- Active investigation for MBs may be warranted in select low-risk patients.
- Understanding the role of MBs can guide therapeutic strategies and improve patient outcomes.

01:26Coronary Artery Disease II: Pathophysiology
847
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...

1.3K
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...

590
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...

01:30Atherosclerosis I: Introduction
1.7K
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...

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...
