Q

PRO BNP is a lab for what? and what is the physiology?

A
  • BNP is a lab to check for heart failure
  • when the heart is stretched/dilated it releases BNP in the blood, and tells the kidneys to get rid of some of this volume stretching my heart

Q

What are the sx of left systolic HF?

A
  • dyspnea with walking
  • PND, post nocturnal dyspnea, wake up short of breath and then walk around
  • orthopnea, need to sleep with pillows

Q

What are the PE findings for left systolic heart failure?

A
  • rales/crackles

- apical impulse displaces downward and to the left

Q

When palpating the heart apex in its normal left side and midclavicular line at the fifth intercostal space you feel an apical lift what does this tell you.

A

-tells you the person has LVH

Q

An echo says the patient has left ventriclular hypertrophy and an ejection fraction less than 40% tells you what?

Q

You see a patient of yours in the ER. You have been treating him for chronic left systolic heart failure. He has been on ACEI, Bblocker, and 20 mg diuretic. Now he is short of breath and unstable. How do you treat.

A

1) give Oxygen
2) stop the Bblocker, this make acute HF worse
3) Give Nitroglycerin
4) double the dosage of diuretic, now give it IV

Q

For chronic left ventricular heart failure you should be treating with these three medications for control?

A
  • ACEI
  • Bblocker
  • loop diuretic
17
Q

A hypertrophic or thick ventricular wall that will not relax. It is a stiff ventricle.

A

Left diastolic heart failure

18
Q

An older lady or a Black comes in with sudden shortness of breath and elevated blood pressures, forgot to take BP meds. S4 heart sound is noted. Rales are noted. Dyspnea is noted. An apical heave is noted due to big thick left ventricle. Whats she got?

A

ACUTE Left diastolic heart failure

echo will show her ejection fraction will be normal and will show LVH

19
Q

Compare tx of chronic and acute Left diastolic heart failure

A

Chronic, tx with ACIE or Bblocker or CCB (this is not a volume problem so you don’t need a loop diuretic)

Acute, ACEI, loop diuretic, Nitro, O2 (just like left systolic heart failure)

20
Q

You can use digoxin in Left systolic heart failure, what about left diastolic heart failure?

A

Never use digoxin in left diastolic HF, you have a too thick left ventricle and we don’t want to make it even more difficult for them to contract

21
Q

Guy presents with leg edema, JVD, liver enlargement, PMI displaced toward the right sternal border apical impuse. He has no rales/crackels. What do you suspect? How do you make a definitive Dx?

A
  • right heart failure
  • Dx initial by echo with doppler, then gold standard is right heart catherization

but look for things that might mimic right heart failure like tamponade, and constrictive pericarditis

Tx the underlying cause of the right heart failure

22
Q

You see a guy with JVD and clear lungs, what might you suspect?

A

right heart failure

23
Q

Metabolic demand is more than the heart can pump at maximum

A

High cardiac output failure

24
Q

young lady comes in with tachycardia at rest, what might be the cause of her high cardiac output failure?

A
  • thyroid storm
  • severe anemia
  • shunts
  • berry-berry or thiamine deficiency
25
Q

Hypotension with hypo-purfusion despite adequate left ventricular filling

A

Cardiogenic Shock

26
Q

Left ventricle fills ok but is too weak to pump it out to the body

A

Cardiogenic Shock

27
Q

The number one cause of cariogenic shock is?

A

AMI

28
Q

Meds to tx cardiogenic shock

A

-fluids

  • Dobutamine
  • Norepinephrine

Balloon pump in aorta into the atrium which forces more blood to the coronary arteries
