failure
1. Review cardiac anatomy + physiology
2. Explain HF in terms of definition, etiology, pathophysiology,
compensatory mechanisms
Definition:
• Heart too weak to pump efficiently, insufficient CO
• An abnormal condition of impaired cardiac pumping or filling
• The heart can’t produce enough cardiac output to adequately perfuse the body
• Characteristics: ventricular dysfunction, reduced exercise tolerance, diminished quality of
life, shortened life expectancy
, lOMoARcPSD|20734855
• It is a syndrome, not a disease
• Associated w/ HTN, CAD + MI
Primary Risk Factors:
1. CAD
2. HTN
Contributing/Precipitating Risk Factors:
1. Diabetes
2. Tobacco use
3. Obesity
4. High serum cholesterol
Causes:
F – faulty heart valves (stenosis/narrow, regurgitation/leaks, infection)
A – arrhythmias (a fib or tachycardia)
I – infarction
L – lineage (congenital, family hx)
U – uncontrolled HTN stiffens heart walls
R – recreational drug use (cocaine) + alcohol abuse
E – evaders (viruses or infections that attack heart muscle)
Classifications:
a. Systolic failure
b. Diastolic failure
Reduced Ejection Fraction HF
*Systolic HF*
Causes:
• Impaired contractile function (MI)
• Increased afterload (HTN)
• Cardiomyopathy
• Mechanical abnormalities
• Virus
