Q

Q

What are the characteristics of systolic left heart failure?

A
  • systolic - S3 (rapid ventricular filling during early diastole in the mechanism responsible for the S3)
  • dilated thin-walled weak left ventricle: often due to CAD or heart attack which causes the muscle to die
  • dyspnea, PND, orthopnea, rales, crackles, displaced downward and to the left apical impulse
  • dilated left ventricle and a low ejection fraction <40%
  • treat with Ace inhibitor + beta-blocker + loop diuretic
  • systolic left heart failure is diagnosed and treated based on class: Class I, II, III and IV and patients can go from controlled class I to poorly controlled and worsening class II, III, or IV and back
  • acute worsening of heart failure: O2 + Ace + stop beta-blocker + start nitroglycerine and a double dose of diuretic IV (once stable go back on beta-blocker and PO loop diuretics

Q

  • increases over 55 years of age, commonly in patients with hypertension
  • patients will have problems when blood pressure increase, often when patients forget to take their medications
  • dyspnea and rales with an apical heave or lift
  • ejection fraction is usually normal
  • treat with Ace inhibitor + beta blocker or CCB (do not use diuretics in stable chronic diastolic failure)
  • never use digoxin for diastolic heart failure
  • acute = same as systolic heart failure = Ace inhibitor + loop diuretic IV + NTG + O2

Q

What are the characteristics of right heart failure (right ventricle)?

A
  • causes: pulmonary HTN - the right heart is unable to easily pump blood into the lungs, the most common cause of right heart failure is left heart failure
  • no rales, JVD, and leg edema
  • diagnose with echo and doppler, gold standard is high heart cardiac catheterization
  • treat the underlying condition

Q

What are the characteristics of high output cardiac failure?

A
  • caused by increased metabolic demand - metabolic demand is higher than the heart can pump at maximum
  • hyperthroidism
  • severe anemia
  • beriberi or thiamine deficiency
  • will have tachycardia at first but once the heart tires it will look like systolic failure because the heart will dilate and weaken
  • treat like heart failure and acute CHF, treat the underlying condition

Q

What are the characteristics of deteriorating mental status/unconscious patient?

A

level of consciousness is evaluated by attempting to wake patients first with verbal commands, then with non-noxious stimuli, and finally with noxious stimuli (eg, pressure to the supraorbital ridge, nail bed, or sternum)

  • the Glasgow Coma Scale was developed to asses s patients with head trauma
  • for head trauma, the score assigned by the scale is valuable prognostically
  • for coma or impaired consciousness of any cause, the scale is used because it is a relatively reliable, objective measure of the severity of unresponsiveness and can be used serially for monitoring
  • asymmetric motor responses to pain or deep tendon reflexes may indicate a focal hemispheric lesion
