Summary
Enhanced angiotensin-converting enzyme (ACE) and vascular endothelial growth factor (VEGF) expression promotes coronary atherosclerosis progression and plaque instability. These findings highlight ACE and VEGF as key factors in the development of human coronary artery disease.
Area of Science:
- Cardiovascular Biology
- Molecular Medicine
- Pathophysiology
Context:
- Coronary atherosclerosis is a leading cause of cardiovascular disease.
- The roles of specific molecular factors in plaque progression and destabilization require further elucidation.
- Understanding these mechanisms is crucial for developing targeted therapies.
Purpose:
- To investigate the expression and role of angiotensin-converting enzyme (ACE) and vascular endothelial growth factor (VEGF) in human coronary atherosclerosis.
- To determine the association of ACE and VEGF expression with plaque progression and destabilization.
- To elucidate the contribution of ACE-mediated angiotensin II formation to atherosclerotic development.
Summary:
- Immunohistochemical analysis of coronary arterial segments revealed enhanced ACE expression in atheromatous and ruptured plaques.
- Increased ACE expression is linked to greater atherosclerosis progression through elevated vascular angiotensin II levels.
- Distinct VEGF expression patterns were observed, suggesting a role in both the progression and destabilization of human coronary atherosclerosis.
Impact:
- Provides evidence for the significant contribution of ACE and VEGF to the pathogenesis of coronary atherosclerosis.
- Identifies potential molecular targets for therapeutic intervention in managing atherosclerotic cardiovascular disease.
- Enhances understanding of the complex interplay between inflammatory and growth factor pathways in plaque development.

Overview
01:30Coronary Artery Disease I: Introduction
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...
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...
01:30Atherosclerosis 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...
01:27Atherosclerosis 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)...
01:30Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
