Choose: (1) Preload (2) Contractility (3) Afterload More vol of blood coming in = greater stretching = greater contraction
(2) Contractility
26
When does the myocardial cells begin to stretch?
When ventricles are being filled with blood
27
During _____ there is colonization throughout the muscle tissue that causes initial stress
ventricular filling
28
“pulse pressure” pressure produced by ventricle to push blood out of the aorta (120 - 80 = 40 mmHg)
Pressure Gradient
29
Normal blood pressure
120/80 mmHg
30
BP: 120/100 -> pressure gradient is 20 mmHg (120 - 100). Pressure is too low for ventricles to push out blood. What will the body do?
You need to increase your systolic pressure
31
pressure exerted when blood is ejected in arteries (yng una)
Systolic BP
32
pressure blood exerts within arteries between heartbeats
Diastolic BP
33
TYPES OF CONGESTIVE HEART FAILURE (1) (2) (3) (4)
1 Systolic heart failure 2 Diastolic heart failure 3 High output heart failure 4 Right side heart failure
34
Choose: (1) Systolic heart failure| (2) Diastolic heart failure| (3) High output heart failure | (4) Right side heart failure Ventricular Myocardial cells cannot generate enough power to create higher stroke volume * Inability of the heart to push blood out * Heart cant contract properly = leads to low CO
(1) Systolic heart failure
35
Choose: (1) Systolic heart failure| (2) Diastolic heart failure| (3) High output heart failure | (4) Right side heart failure * Heart too restricting, stiff & fibrotic (leads to) * Doesn’t get enough venous return * Myocardial cells don’t stretch properly * Valves are very week
(2) Diastolic heart failure
36
Choose: (1) Systolic heart failure| (2) Diastolic heart failure| (3) High output heart failure | (4) Right side heart failure left ventricle exerts too much to push blood out inc in oxygen demand & dec oxygen supply = heart: work harder, tissue: demands more oxygen
(3) High output heart failure
37
Choose: (1) Systolic heart failure| (2) Diastolic heart failure| (3) High output heart failure | (4) Right side heart failure Common Cause *decrease/low contractility of myocardial cells * inc preload due to existing low contractility
(1) Systolic heart failure
38
conditions that could lead to low contractility
(1) Myocardial Infarction (2) Dilated Cardiomyopathy
39
heart is too big or cardiomegaly & ventricles are too thin = cant generate enough power to pump blood out; caused by infection, viral or idiopathic
Dilated Cardiomyopathy
40
significantly left side of the anterior left ventricle
Myocardial Infarction
41
* when you have 140 ml of blood in left ventricle & right ventricle contracts, * 40 ml: pushed out; 100 ml: left in left ventricle * when left ventricle continues to accept blood from pulmonary circuit
Venous Return
42
“vomiting” putting in & pushing it out
Regurgitation
43
* Disease that could aggregate diastolic heart w regards to inc preload & low contractility * Conditions that allow venous return
Mitral & Aortic Valve Regurgitation
44
blood regurgitates due to * weak or flappy valves * inc preload (blood vol from lung & blood regurgitation will mix & go back to ventricle)
Mitral Valve Regurgitation “bicuspid valve”
45
blood regurgitates back due to weak aortic valve when ventricles contract
Aortic Valve Regurgitation
46
2 Aspects to Consider in Diastolic Heart Failure
(1) Low preload (2) High afterload

Low Preload causes: (1) (2) (3)
1 Constrictive Pericarditis 2 Restrictive Cardiomyopathy 3 Myocardial Infarction (MI)
48
Choose: (1) Constrictive Pericarditis (2) Restrictive Cardiomyopathy (3) Myocardial Infarction (MI) heart is too stiff, doesn’t want to expand
(2) Restrictive Cardiomyopathy
49
Choose: (1) Constrictive Pericarditis (2) Restrictive Cardiomyopathy (3) Myocardial Infarction (MI) necrotic heart tissue will be replaced with fibrotic tissue = heart will not stretch
(3) Myocardial Infarction (MI)
50
Choose: (1) Constrictive Pericarditis (2) Restrictive Cardiomyopathy (3) Myocardial Infarction (MI) (inflammation of pericardial sacs) sacs become inflamed & lead to fibrosis, pushes heart to itself
(1) Constrictive Pericarditis
51
Disease that can lead to Restrictive Cardiomyopathy (5) ACASH
1 Cancer 2 Any accumulation of substance 3 Amyloidosis 4 Sarcoidosis 5 Hemochromatosis
52
Choose: (1) Cancer (2) Any accumulation of substance (3) Amyloidosis (4) Sarcoidosis (5) Hemochromatosis accumulation of amyloid protein, restricts stretching
(3) Amyloidosis
53
Choose: (1) Cancer (2) Any accumulation of substance (3) Amyloidosis (4) Sarcoidosis (5) Hemochromatosis accumulation of iron in ee; iron deposits in between myocardial cells (leads to) = restrictive cardiomyopathy
(5) Hemochromatosis
54
Choose: (1) Cancer (2) Any accumulation of substance (3) Amyloidosis (4) Sarcoidosis (5) Hemochromatosis accumulation of non caseating granulomas found in diff tissues of the body

High afterload is caused by (1) (2) (3)
1 Hypertension 2 Aortic Valve Stenosis 3 Cortication of aorta
56
Choose: 2 Aortic Valve Stenosis 3 Cortication of aorta part of aorta becomes narrow (coarctation) LV should produce pressure to overcome existing pressure of cortication
