Verified Correct Answers
Stroke Volume
Amt of blood ejected by ventricle during a contraction
What does digoxin do?
increases cardiac contractibility
Preload
volume of blood in ventricles at end of diastole
Buerger's disease pt needs to avoid smoking & stimulants? (T/F)
True
After load
resistance left ventricle must overcome to circulate blood
modifyable risk factors for heart disease
-obesity
-sedentary lifestyle
-smoking
-DM
-HTN
coronary artery disease (CAD)
-a condition affecting arteries of the heart that reduces the flow of blood & delivery of
oxygen & nutrients to the myocardium
,-most often caused by atherosclerosis
-avoid LDL & low fat diet
coronary artery disease (CAD) s/s
-n/v
-tachycardia/palpitations
-chest discomfort/pain
-undue fatigue
-clammy skin
-HTN
Stable angina
-Pain last less than 15 min
-occurs w/ exercise or activity & resolves w/ rest
-activity induced
unstable angina
-chest pain that occurs while a person is at rest and not exerting himself
-may not be relieved by nitro & is unpredictable
-not relieved by nitroglycerine
EKG/ECG
measures electrical rhythm of heart
cardiac catheterization
, -uses stents
-inserts via femoral artery; used to place stands or remove clots
-commonly done for MI
myocardial infarction (MI)
-heart attack; death of myocardial tissue (infarction) caused by ischemia (loss of blood flow)
-no O2 to tissues
-cool; clammy skin
-chest pain; tightness/pressure
MI treatment
M: Morphine
O: O2
N: Nitro
A: Aspirin
Common causes of HF
-coronary artery disease (CAD)
-HTN
Brain Natriuretic Peptide (BNP)
-protein made by heart & BV
-used to determine progression of HF
-high BNP: not in shape
-low BNP: healthy
Troponin
