14: Drugs for Heart Failure

Question 0

Angiotensin II

Answer 0

A substance produced by the body that causes blood vessels to narrow or constrict, raising blood pressure

Question 1

Afterload

Answer 1

Total peripheral resistance that the heart must overcome to pump blood out of the heart. It includes mean arterial pressure (MAP)

Question 2

Cardiac output

Answer 2

The amount of blood pumped by the heart in one minute

Question 3

Contractility

Answer 3

The ability of the fibers of living muscle to contract or shorten

Question 4

Diastolic left heart failure

Answer 4

In adequate relaxation or stiffening of that ventricle that prevents the heard from filling enough before contraction

Question 5

Ejection fraction

Answer 5

The amount or percentage of blood that is pumped out of the heart to the body with each heartbeat

Question 6

Heart failure

Answer 6

Occurs when the heart cannot pump enough blood to meet the needs of the body . Also called pump failure.

Question 7

Jugular vein distention

Answer 7

Permanent, enlarged, pulsing jugular vein when a patient is sitting up. A sign of heart failure.

Question 8

Mean arterial pressure (MAP)

Answer 8

Average systolic blood pressure and a large arteries, including the aorta. For the average for the adult than normal and AP is around 100 mmHg

Question 9

Myocardial hypertrophy

Answer 9

Enlargement of the myocardial or heart muscle

Question 10

Preload

Answer 10

The stretch, tension, or volume of blood present in the ventricles of the heart after passive filling in atrial contraction and before ventricular contraction

Question 11

Renin-angiotension system (RAS)

Answer 11

A buddy system pathway that causes the release of two chemicals, angiotensin II and aldosterone, which act together to increase blood pressure

Question 12

Systolic left heart failure

Answer 12

Condition in which the hurt is unable to contract forcefully enough to pump enough blood to meet the needs of the body
