1

clinical manifestations associated with left ventricular systolic dysfunction - forward

-fatigue
-oliguria
-increased heart rate
-faint pulses
-restlessness
-confusion
-anxiety

2

clinical manifestations associated with left ventricular systolic dysfunction - backward

-dyspnea on exertion
-orthopnea
-cough
-postural nocturnal
-cyanosis
-basilar crackles

3

clinical manifestations associated with right ventricular systolic dysfunction - forward

-fatigue
-oliguria
-increased heart rate
-faint pulses
-restlessness
-confusion
-anxiety

4

clinical manifestations associated with right ventricular systolic dysfunction - backward

-hepatomegaly
-ascites
-splenomegaly
-anorexia
-subcutaneous (peripheral) edema
-jugular venous distention

5

factors decreasing preload

-hypovolemia
-excessive vasodilation
-increased intrathoracic pressure
-cardiac tamponade
-RV infarction, failure
-tachyarrhythmias
-loss of atrial "kick"

6

factors increasing preload

-heart failure
-hypervolemia
-bradydysrhythmias

7

factors decreasing afterload

-hypotension
-vasodilation
-drug effects

8

factors increasing afterload

-vasoconstriction from SNS stimulation
-hypertension
-pulmonary hypertension
-hypercoagulability
-aortic valve stenosis

9

factors decreasing contractibility

-myocardial ischemia or infarction
-cardiomyopathy
-hypoxemia
-acidosis
-drug effects

10

factors increasing contractibility

-SNS stimulation
-sympathomimetic drugs

11

blood colloid osmotic pressure

-albumin trying to keep blood in capillaries
-works against interstitial fluid hydrostatic pressure

12

interstitial fluid osmotic pressure

-tends to move fluid out of the capillaries via large plasma proteins (albumin)
-works in opposition to the blood hydrostatic pressure

13

blood hydrostatic pressure

attempts to force fluid outward through the capillary

14

interstitial fluid hydrostatic pressure

attempts to force fluid from the interstitial space into the capillaries

15

lymphatic obstructive

produces lymphedema

16

causes of lymphedema

filariasis or breast (inflammatory carcinoma)

17

BNP

elevated in heart failure

18

causes of heart failure

-coronary artery disease
-idiopathic cardiomyopathy
-metabolic causes
-drugs and toxins
