Heart Failure

Question 1

Contractibility

Answer 1

How well the heart can stretch

Question 2

Cardiac Output (CO)

Answer 2

Heart rate and stroke volume

Question 3

A large heart is …

Answer 3

bad

Question 4

Systolic failure

Answer 4

Pump problem!

Inability to pump blood forward

Question 5

Causes of systolic failure

Answer 5

Cardiac myopathy, increased after load, impaired contractile function, and mechanical abnormalities

Question 6

Systolic Failure Affect

Answer 6

Decreased LV ejection fraction (EF)

Less than 45%

Question 7

Normal EF

Answer 7

55-60%

Question 8

EF

Answer 8

How much volume can be pumped out of the heart

Question 9

Diastolic Failure

Answer 9

Fill problem!

Impaired ability of the ventricles to relax and fill

Question 10

Causes of diastolic failure

Answer 10

Left ventricular hypertrophy, R/T hypotension, older age, female, diabetes, obesity

Question 11

Diastolic failure affect

Answer 11

Decreased SV and CO
Preserved EF

Question 12

Volume problem =

Answer 12

Increased HR compensation

Question 13

Right sided heart failure

Answer 13

cor pulmonal

RV does not PUMP effectively
Fluid backs up into venous system, and it moves into tissues and organs

Question 14

Right sided heart failure cause

Answer 14

left sided heart failure most common

Resp issues

Question 15

Simple Right sided HF

Answer 15

Can’t pump into the lungs, backs up into body, fluid overload leads to edema
