Module 8: Cardiovascular care Flashcards
what is the formula for:
Cardiac output?
CO= SV x HR (stroke volume x) heart rate
what is the formula for:
BP
BP= CO x SVR
what is the formula for:
MAP (mean arterial pressure)
MAP = (SBP +2DBP) divided by 3
MAP is the average pressure in a patient’s arteries during one cardiac cycle.
what is the formula for:
Pulse pressure
PP = SBP - DBP
what is Cardiovascular disease and what does it include?
refers to a class of diseases that involve the heart and/or blood vessels.
Includes:
Hypertension Coronary artery D cerebrovascular
Stable angina acute coronary syndrome (ACS)
Unstable angina Myocardial infarction (MI)
NSTEMI STEMI
What are the modifiable risk factors for CVD
– high blood pressure
– high cholesterol (high LDLs/ low HDLs)
– overweight and obesity/ waist circumference
– physical inactivity
– low fruit and vegetable intake
– alcohol and smoking
– stress
What are the non-modifiable risk factors for CVD
– family history and genetics
– age, gender, ethnicity
what is CAD?
Narrowing/ blockage of the coronary arteries, usually caused by atherosclerosis
what is a stable angina?
chest pain or discomfort that most often occurs with activity or emotional stress
what is Acute coronary syndrome (ACS) ?
blood supply to myocardium is suddenly blocked
what is unstable angina?
a condition in which your heart doesn’t get enough blood flow and oxygen. may lead to a heart attack.
What is a STEMI and what is a NSTEMI?
A STEMI or ST-elevation myocardial infarction is caused by a sudden complete (100 percent) blockage of a heart artery (coronary artery).
A non-STEMI is usually caused by a severely narrowed artery but the artery is usually not completely blocked.
