L31: Heart Failure And Circulatory Shock

Front 1

________ is the failure of the cardiovascular system to adequately perfuse vital organs and cells of the body.

Back 1

circulatory failure

Front 2

_______ is the inability of the heart to pump forward enough blood to meet the metabolic demands of the body or the ability to do so only at an abnormally elevated filling pressure.

Back 2

congestive heart failure (CHF)

Front 3

CHF is frequently caused by a defect in _______.

Back 3

myocardial contraction

Front 4

What are the three main causes of heart failure?

Back 4

-hemodynamic overload
-inadequate coronary flow
-cardiomyopathy

Front 5

What are six predisposing factors of heart failure?

Back 5

-coronary heart disease
-hypertension
-obesity
-cigarette smoking
-diabetes
-valvular heart disease

Front 6

______ failure is problems resulting from reduced cardiac output and the subsequent fall in arterial pressure.

Back 6

forward

Front 7

______ failure leads to underperfused tissues, which leads to hypoxia and altered metabolism.

Back 7

forward

Front 8

______ failure is problems from reduced ability to transfer blood from the venous circulation to the arterial circulation.

Back 8

backward

Front 9

______ failure leads to pulmonary and system congestion.

Back 9

backward

Front 10

______ is the shortness of breath.

Back 10

dyspnea

Front 11

______ is discomfort in breathing, especially lying down.

Back 11

orthopnea

Front 12

______ is shortness of breath that appears suddenly at night, due to reabsorption of interstitial fluid while lying down.

Back 12

paroxysmal nocturnal dyspnea

Front 13

List the six symptoms of heart failure discussed.

Back 13

-dyspnea
-orthopnea
-paroxysmal nocturnal dyspnea
-fatigue
-peripheral edema
-right upper quadrant discomfort

Front 14

______ is inadequate blood flow to peripheral tissues which leads to tissue damage.

Back 14

hypovolemic shock
