Lecture 43 and 44 Flashcards
HRrEF
HF reduced ejection fraction –> failure of pumping mechanism
Systolic dysfunction
HRmrEF
mid-range ventricular dysfunction LVEF–> 41% -49%
HFeEF
HF preserved ejection fraction
diastolic dysfunction–> abnormal cardiac relaxation, stiffness, or filling; part of normal human aging
risk factor to developing HFpEF but these are not synonymous
What are the different types of heart failure:
Cardiogenic HF: +acute cardiac event. PE: cool, mottled periphery, small volume pulse, cardiomegaly, +JCP, +S3, +systolic and diastolic murmurs
Non-cardiogenic:+underlying disease
PE: warm periphery, bounding pulse
Acute Decompensated HF:
Heart Failure:
S/S:
When heart can’t pump enough blood and O2 to organs in the body
breathlessness due to +LVEDP –> pulmonary congestion –> pulmonary edema
What is the cost of HF?
MC and expensive reason for preventable hospital stays.
Risk factors with HF
CAD–> coronary heart disease
MI, DM, HTN, obesity, valvular heart disease,
smoking
Mask symptoms: hypothyroidism, CKD, CAD, DM, Anemia, Thyroid disorder, OSA, AFib, Valvular Disease
What are HF physiological risk factors?
reduced pulmonary reserve
reduced cardiac reserve
Skeletal muscle dysfunction
Ejection Fraction
amount of blood pumped out/ amount of blood in chamber
Normal
Borderline
Reduced
Normal: 50-70%
Borderline: 41%-49%
Reduced: <40%
HFeRF
HF of reduced ejection, systolic dysfunction
HRmrEF
mid range ventricular dysfunction LVEF 41-49%
HFpEF
preserved ejection fraction
Diastolic dysfunction abnormal cardiac relaxation, stiffness or filling, part of human human aging
