Systolic/ Diastolic HF Article

Question 1

Diastolic and Systolic Heart Failure are ________ but ________.

Answer 1

different, similar

Question 2

“Ventricular chamber is unable to accept an adequate amount of blood during diastole at nml diastolic pressures and at volumes sufficient to maintain an appropriate stroke volume” is a proposed definition of __________.

Answer 2

That would be Diastolic Heart Failure

(also, EF is preserved)

Question 3

Well, then. That means that “a pathophysiological abnormality of cardiac function is responsible for the failure of the heart to pump blood at a rate commensurate with the requirements of the metabolizing tissues” is one definition of _______.

Answer 3

Systolilc Heart Failure

(Also, just think inadequate emptying)

Question 4

For the most part, in the SHF patient, they [do/ do not] typically also have DHF.

Answer 4

DO!

Question 5

Conversely, DHF patients typically [do/ do not] exhibit ventricular dysfunction (SHF).

Answer 5

DO NOT (for the most part)

Question 6

T/F:

S/S, neurohormonal levels, ECG, and radiologic studies can differentiate between DHF and SHF.

Answer 6

False, muthatrucka!

Question 7

After the confirmation of heart failure, what measure is utilized to distinguish DHF from SHF?

Answer 7

EF, muthatrucka!

Question 8

Cardiac catheterization is occasionally indicated for HF only when ________ is strongly suspected. (and even then, which type of HF is irrespective)

Answer 8

myocardial ischemia

Question 9

Time for Incidence/ Prevalence questions!!!! (YAY!!!)

Answer 9

Nope. Fuck that shit, they’re stupid numbers, trust me.

Question 10

But, just in case you’re curious:

SHF incidence?

DHF incidence?

% of HF that is DHF?

Answer 10

SHF: 61-68%

DHF 16-39%

DHF/HF_t: 40-71%

See what I mean? Screw these numbers, I think one of them tried to steal your nifty hat the other day…

Question 11

Per echo-dopplers, Left ventricle diastolic dysfunction have a [higher/ lower] overall mortality (adjusted for sex, age, and EF)

Answer 11

HIGHER!!!

Sudden diastolic-mediated cessation of total metabolic activity, bitches!

Question 12

In DHF, the following are [increased/ decreased]

LV mass

Mass/Cavity (a ratio of sorts)

Wall thickness

End-Diastolic stress

Answer 12

These suckers are increased.

Question 13

So, in SHF, the following are [increased/ decreased]

LV Cavity size

LV Mass

End Diast. stress

End systolic stress

End-diast. volume

End-syst. volume

EF

Answer 13

All are INCREASED

EXCEPT!!!!

EF is decreased (duh)

Question 14

In DHF, LV dilation typically does not occur, while it ALWAYS occurs in SHF.

So, what would cause LV dilation in DHF?

Answer 14

Ischemic insult or infarction

Question 15

Therapeutic options for DHF?

Answer 15

None really.

ARBs may reduce morbidity, but not mortality.

Statins have been reported to reduce mortality in DHF as well as SHF.
