病理生理 冠状动脉疾病 Coronary Artery Disease C A Dppt课件

Anatomy
Additional arteries branch off the two main coronary arteries to supply the heart muscle with blood. These include the following:
Circumflex artery (Cx) The circumflex artery branches off the left coronary artery
Figure C: A coronary artery narrowed by plaque. The buildup of plaque limits the flow of oxygen-rich blood through the artery. The inset image shows a crosssection of the plaque-narrowed artery.
Non-obstructive coronary artery disease, with arteries that inappropriately constrict or malfunction after branching into tiny vessels, or are squeezed by overlying heart muscle
Spontaneous coronary artery dissection (SCAD), in which the layers of the artery suddenly split

Obstructive coronary artery disease, with narrowed or blocked vessels
Anatomy
The two main coronary arteries are the left and right coronary arteries. The left coronary artery (LCA), which divides into the left anterior descending artery and the circumflex branch, supplies blood to the heart ventricles and left atrium. The right coronary artery (RCA), which divides into the right posterior descending artery and a large marginal branch, supplies blood to the heart ventricles, right atrium, and sinoatrial node (cluster of cells in the right atrial wall that regulates the heart’s rhythmic rate).

Definition
CAD
Coronary artery disease (CAD) causes changes in both structure and function of the blood vessels. Atherosclerotic processes cause an abnormal deposition of lipids in the vessel wall, leukocyte infiltration and vascular inflammation, plaque formation and thickening of the vessel wall. These changes lead to a narrowing of the lumen (i.e., stenosis), which restricts blood flow.

the back of the heart.
Left anterior descending artery (LAD) The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the heart.
