Myocardium
What is the thickest layer
- cardiomyocytes provide contractile force
of the heart and why?
- contains coronary arteries & veins
right coronary artery (RCA)
What are the two main
left coronary artery (LCA)
coronary arteries and
- coronary arteries supply blood to different areas of
what do they do?
the heart
Can occlusion of either of YES!
the main coronary arteries
cause left ventricular
damage?
- supplies right atrium & right ventricle & portion of
What does the right posterior wall of left ventricle
coronary artery supply? - SA & AV nodes & bundle of His receive blood from
right coronary artery
What does the left - supplies left atrium & left ventricle
coronary artery supply?
, •Collateral circulation assists in supplying blood &
oxygen to myocardium that has become ischemic
following stenosis of one or more coronary arteries
d/t CAD
•Formation of collateral arteries can restore
How does collateral circulation following arterial occlusion (CAD)
circulation work? •CAD can take decades to develop & progress.
Collateral circulation develops at same time as
atherosclerotic changes are taking place so takes time
to develop
•because of collateral circulation, CAD does not
produce symptoms until far advanced!
•arteriogenesis (new artery growth branching from
What are the two ways
preexisting arteries)
collateral vessels are
•angiogenesis (growth of new capillaries within a
formed?
tissue)
What node of the heart Sinoatrial (SA) node
acts as the pacemaker?
What does a normal ECG
look like?
Endothelium injury
Inflammation of endothelium
Cytokines released
Cellular proliferation
What is the progression of Macrophage migration
atherosclerosis? Low-density lipoproteins (LDL) oxidation (foam cell
formation) with oxidative stress
Fatty streak
Fibrous plaque
Complicated plaque
