Question 20

what is heart failure

Answer 20

the inability of the heart to pump adequate amounts of blood to meet the body’s oxygen and nutrient needs

end stage of any heart issue

Question 21

what is systolic HF

Answer 21

inability of the heart to contract efficiently enough to pump blood around the body

Question 22

what is diastolic HF

Answer 22

reduced heart compliance, impaired ventricle filling
