Damage to endothelium->inflammation->fatty streak->fibrous plaque->complicated lesion
Chronic disease characterized by abnormal thickening and hardening of the vessel walls.
Can consist of fat, bacteria, foreign substances or air.
Pathogenesis of ACS
Atherosclerotic plaque ruptures->thrombus formation over lesion plus vasoconstriction of vessel->unstable angina or MI
Importance of seeking help stat with MI
After 20 minutes of ischemia, cellular death and tissue necrosis occurs.
Acute Pericarditis

What is happening in cardiac tamponade

Heart Failure
A general term used to describe several types of cardiac dysfunctions that result in inadequate perfusion of tissues.
The common pathway in all types is impaired cellular metabolism – cells switch from aerobic to anaerobic metabolism.
Increased carbon dioxide in the arterial blood.
Reduced oxygenation of arterial blood.
Reduced oxygenation of cells in tissues.
Acute Respiratory Failure
Inadequate gas exchange where PaO2 ≤ 50 mm Hg or where PaCO2 ≥ 50 with pH ≤ 7.25
Collapse of lung tissue that can usually be prevented (and treated) by deep breathing and using a spirometer.
Enlargement and destruction of alveolar walls with loss of elasticity and trapping of air.
Thick mucus, mucosal edema and smooth muscle spasm causing obstruction of small airways.
Pulmonary Hypertension
This condition results from constriction, or tightening, of the blood vessels on the right side of the heart.
Cor Pulomale
