Learning Outcome 4 Flashcards
Coronary artery disease
Occurs when arteries supplying blood to the heart become block by atherosclerosis.
Atherosclerosis
Is an accumulation of lupus or fatty plaques within and along the lining of the arterial walls. (Progressive condition that can begin at any age & can occur anywhere in body)
Angina Pectoris
Chest pain resulting from lack of circulation of oxygen-rich blood to the heart muscle
Symptoms of angina
Aching, sharp pain, tingiling, burning sensation, pressure ,squeezing or tightness in chest area which may radiate to the arms, jaw or neck
Stable angina
Result of increased oxygen demand placed on the heart from exertion or excersize this is not an urgent condition
Unstable angina
Occurrs more frequently and is generally a result of narrowing of the already clogged artery this is an emergency
Myocardial infarction
Heart attack myocardial is heart muscle infarction means death of a tissue
Difference between myocardial infarction & angina
Myocardial infarction: part of the heart tissue actually dies as a result of decrease in oxygen flow.
Angina : there is no death tissue
Systolic pressure
Systolic: higher pressure, it measures amount of force needed when the heart contracts to pump blood out of heart into arterial circulation
diastolic pressure
Is the lower pressure. It represents the pressure in the arteries between contractions when heart is at rest
Hypertension
Define as systolic reading over 140mm and a systolic reading over 90mm ( high blood pressure)
What is normal heart reading
120/80
Essential primary hypertension
Most common type , occurs when there is an increase in blood pressure without any other medical causes the cause is in known
Secondary hypertension
Specific cause such as kidney disorders, Tumors, pregnancy or medications
What is hypertension known as
Silent killer
