Heart Failure definitions

Question 1

The amount of blood pumped out by the ventricle PER CONTRACTION.

Answer 1

Stroke Volume

Question 2

Heart Rate (HR) x Stroke Volume (SV): the absolute (i.e., mL) amount of blood pumped out by the ventricle during a contraction PER MINUTE.

Answer 2

Cardiac Output (CO)

Question 3

CO x systemic vascular resistance (SVR)

Answer 3

Mean Arterial Pressure (MAP)

Question 4

Pressure or volume in the ventricles (usually left ventricle) at the end of the diastolic heart phase; determined by amount of blood returned to the atria (venous return)

Answer 4

Preload

Question 5

LVEDV

Answer 5

Left Ventricular End Diastolic Volume (or pressure)

Question 6

Pressure in the ventricles at the peak of the systolic heart phase; determined by systemic vascular resistance, in general.

Answer 6

Afterload

Question 7

Ventricular contractility

Answer 7

Inotrope

Question 8

heart rate

Answer 8

Chronotrope

Question 9

Ventricular relaxation

Answer 9

Lusitrope

Question 10

Related to cardiac output; the percentage of blood pumped out by the ventricle during a contraction; 55-65% in normal, healthy heart

Answer 10

Ejection fraction (EF)

Question 11

Descriptions of volume status (hyper = excessive, hypo = dehydrated, eu= adequate volume)

Answer 11

Hyper/Hypo/EuVOLEMIA

Question 12

a general term describing disease of the heart muscle

Answer 12

Cardiomyopathy

Question 13

Describes the relationship between stretch of cardiovascular fibers and the force of the cardiovascular contraction.

Answer 13

Frank-Starling mechanism

Question 14

A syndrome of the hearts inability to adequately perfuse and meet the metabolic needs of the body, leading to symptoms of fluid congestion and/or hypoperfusion

Answer 14

Hear Failure (HF)
