Describe Atherosclerosis
Definition
Calcium and fatty material called cholesterol build up and form a plaque inside the walls. The low blood flow to the heart tissue (Coronary Artery Atherosclerosis).
Term

Term
Risk factors of AMI
Definition
Cigarette smoking, HBP, high cholesterol, high blood glucose, lack of exercise, stress, age, family hx of ACS, male.
Term
Angina Pectoris
Definition
For a brief period of time, the heart tissues don't get enough oxygen. Most often a sympton of ahterosclerotic coronary artery disease. When the heart's need for oxygen exceed supply (PT, emotional stress, large meal, sudden fear), symptoms come on. When factor goes away, symptoms usually do too.
Term
Angina symptoms
Definition
Crushing, squeezing, "standing on my chest", felt in midchest under sternum, CAN radiate, usually lasts 3-8 minutes, SOB, nausea, sweating. Usually disappears promptly with rest, O2, and nitro.
Term
Stable Angina
Definition
Pain in the chest of coronary origin that is relieved by the things that normally relieve it in a given patient.
Term
Unstable Angina
Definition
Pain in the chest of coronary origin that occurs in response to progressively less exercise or fewer other stimuli
Term
Difference between AMI and Angina
Definition
May or may not be caused by exertion but can occur at any time, sometimes when a person is sitting quietly or even sleeping; It does not resolve in a few minutes; It may or may not be relieved by rest or nitro.
Term
Physical findings of AMI
Definition
P - Generally increased, sometimes irregular. BP - May fall due to cardiac output, could be normal or usually elevated, Resp - Normal, labored and rapid with CHF, App - Ashen gray, Mental - Impending doom
Term
Cardiogenic Shock
Definition
Heart lacks enough power to force the proper volume of blood through the circulatory system.
Term
CHF
Definition
Failure of the ventricule. The muscle gets so damaged that it can no longer keep up with the return flow of blood from the atria. When it can't contract effectively, the heart will increase HR and the L ventricule will enlarge. The lungs become congested with fluid once the heart fails to pump the blood effectively. The blood backs up in the pulmonary veins, increasing pressure in the capillaries of the lungs. When the pressure in the capillaries exceeds a certain level, the fluid passes through the walls of the capilary vessels and into the alveoli.
Term
Dependent Edema
Definition
Collection of fluid in the part of the body that is closest to the ground.
Term
OPQRST
Definition
Onset, Provocation, Quality of Pain, Radiation, Severity, Time
Term
Nitroglycerin
Definition
Relxaes the muscle of blood vessels, dilated coronary arteries, increases blood flow and the supply of O2 to the heart muscle, decreases workload of heart.
Term
Side Effects of Nitroglycerin
Definition
Cause low BP, severe headache, changes in P,
Term
CABG (Coronary Artery Bypass Graft)
Definition
Blood vessel from chest or leg is sewn directly from aorta to a point beyond obstruction.
Term
PTCA (Percutaneous Transluminal Coronary Angioplasty)
Definition
Dilate the coronary artery.
