  1. What is HF?
    The inability of the heart to pump sufficient blood to meet the needs of the tissues for oxygen and nutrients.
  2. What are some RFs?
    • Lung Disease
    • Diabetes
    • Thyroid disease
    • Smoking/Alcohol
    • Drugs (cocaine)
    • Obesity
    • Age
    • Increased Metabolic Rate
  3. What are some compensatory mechanisms?
    • SNS: increases HR
    • RAAS: release of aldosterone to retain fluid and constrict vessels.
    • ANP/BNP: hormones released by atria or ventricle to increase fluid volume.
    • *High BNP indicates HF.
    • Vent dilation/hypertrophy: increases cellular growth.
  4. What is the main point of the pathophys of HF?
    Decreased CO and Increased demand for O2.
  5. What is used for Diagnostic Studies?
    Echocardiogram: *ejection fraction, size, shape, valves.

    X-ray

    • Labs: electrolytes, CBC, kidney, liver, thyroid
    • BNP
    • UA

    Ventriculography
  6. *The side of the heart that is failing determines the Sx.
  7. Clincial Manifestations of Right Sided HF?
    • Viscera and peripheral congestion
    • Jugular venous distention (JVD)
    • Dependent edema
    • Hepatomegaly
    • Ascites
    • Weight gain
  8. Clincial Manifestations of Left Sided HF?
    • Pulmonary congestion, crackles
    • S3 or “ventricular gallop”
    • Dyspnea on exertion
    • Orthopnea
    • Paroxysmal nocturnal dyspnea
    • Dry, nonproductive cough initially
    • Oliguria
    • Nocturia
  9. See s/sx of hypo/hyper Kalemia.
