What is a coronary lesion?
What is a coronary lesion?
Calcified lesions- Vascular calcification of the coronary arteries is a common process that is active, regulated, and involves atherosclerotic as well as inflammatory and hormonal disease processes.
What does culprit lesion mean?
Background: The term “culprit lesion” is used to designate the coronary stenosis responsible for the symptoms of the pa- tient with coronary artery disease. Its detection is essential when partial revascularization is contemplated.
What is a non culprit lesion?
Nonculprit lesions were categorized as obstructive (≥70% stenosis by visual angiographic assessment) or nonobstructive, and as thin-cap fibroatheroma (TCFA) or non-TCFA by optical coherence tomography criteria. TCFA was defined as a lesion with mean fibrous cap thickness <65 μm overlying a lipid arc >90°.
What are the 3 vessels most commonly affected in acute myocardial infarction?
The left anterior descending artery was the most common culprit artery (48.3%), followed by the right coronary artery (30.9%), and the circumflex artery (20.8%).
What causes coronary artery lesions?
Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis.
What is coronary artery stenosis?
Slow build-up of fatty plaque within the artery wall can cause the artery to narrow, reducing blood flow. Sudden changes in the plaque may cause angina to worsen or may cause a heart attack. A narrowing of a coronary artery is called a coronary artery stenosis.
What is complete revascularization?
10. The authors chose a functional classification, with complete revascularization defined as the placement of at least 1 bypass graft distal to a >50% narrowing in each diseased territory.
What tests confirm a diagnosis of myocardial infarction?
Tests to diagnose a heart attack include:
- Electrocardiogram (ECG). This first test done to diagnose a heart attack records electrical signals as they travel through your heart.
- Blood tests. Certain heart proteins slowly leak into your blood after heart damage from a heart attack.
