Heart Attack (Myocardial Infartction – MI)
Scarring, or death, of the heart muscle due to lack of oxygen. Oxygen-rich blood is blocked by a blood clot in a coronary artery, usually due to plaque-related narrowing of the artery.
An interference with the normal conduction of electric impulses that control activity of the heart muscle. Heart block usually is defined as to the location of the block and the type.
A normal noise produced within the heart during the cardiac cycle that can be heard over the pericardium and may reveal abnormalities in cardiac structure or function.
Instability of the blood pressure.
The study of the movements of the blood and of the forces concerned therein.
The red pigmented complex protein found in the red blood cells that functions to carry oxygen and carbon dioxide.
The cessation of bleeding through normal coagulation or by surgical procedure.
A negatively charged polysaccharide normally found in lung or gut mucosa that naturally prolongs the time it takes blood to clot by catalyzing anti-thrombin III.
Characterized by increased or excessive blood pressure. Hypertension is the most powerful and potent risk factor for stroke.
Temperature above normal.
Decreased blood flow to an organ or tissue such as in shock.
Characeterized by decreased or lower than normal blood pressure. Excessive and prolonged blood pressure reductions may lead to watershed cerebral infarction.
A body temperature significantly below 98.6°F (37°C).
