100
Q

Why are African Americans at higher risk for hypertension?

A

High sodium sensitivity

101
Q

What are two major negative effects of HTN on the cardiovascular system?

A

High damaging forces against the endothelial lining

High resistance against the left ventricle

102
Q

What are the effects of high aortic pressure?

A

Excessive workload in the left ventricle, which can lead to left ventricular failure

103
Q

How does HTN predispose systemic arteries to injury?

A

It creates a high shearing force against artery walls, which causes endothelial weakening and injury, which can specifically cause blindness, kidney failure, stroke, and lower extremity vascular issues

104
Q

What are signs and symptoms of target organ damage in HTN?

A
Chest pain
Dsypnea on exertion 
Palpitations 
Headache
Vision problems
Dizziness
Weakness
Edema
Leg pain
105
Q

What symptoms may people with HTN complain of?

A

Often none

In extreme cases: headache, nosebleeds, blurred vision, palpitations

106
Q

What change serves as the precursor to atherosclerosis?

A

Endothelial injury

107
Q

What are common causes of endothelial injury?

A

Oxidizing free radicals
Shearing force of high BP
High blood glucose levels
Elevated LDL cholesterol

108
Q

Non-modifiable risk factors for atherosclerosis

A

Age
Gender (males earlier)
Race (African American)
Family history

109
Q

Modifiable risk factors for atherosclerosis

A
Diet
Activity level
Obesity
Lifestyle
HTN
Diabetes
110
Q

What is the age difference between men and women in the risk of developing atherosclerosis?

A

Men over 45 are at higher risk

Women over 55 or post-menopausal are at increased risk

111
Q

Why are diabetic patients at higher risk for developing atherosclerosis?

A

Often have elevated triglyceride and LDL levels

Often have vascular changes

112
Q

Why does smoking increase atherosclerosis risk?

A

Smoke contains free radicals that cause endothelial injury

Smoke decreases HDL levels

113
Q

What lifestyle factors contribute to the development of atherosclerosis?

A

Tobacco use
Excess alcohol use
Stress

114
Q

What is the bodily process of atherosclerosis development?

A

Endothelial injury brings WBCs and platelets to injury site
WBCs ingest LDL cholesterol
These cholesterol-laden WBCs become foundation for atherosclerotic plaque

115
Q

What happens over time with atherosclerotic plaques?

A

It enlarges and becomes calcified and turns into a fibrous platelet cap (atheroma)
The expanding plaque stretches the vessel to its limit, and the vessel becomes stiff and hardened

116
Q

What signs and symptoms may be present when atherosclerosis has caused organ dysfunction?

A
Chest pain
SOB
Palpitations 
Leg pain
Dependent edema
117
Q

128
Q

What happens to contractility when afterload increases?

A

Contractility decreases, so less blood is ejected from the heart

129
Q

What does RAAS stand for?

A

Renin-angiotensin-aldosterone system

130
Q

Describe renin and its role in BP

A

Released from kidneys when renal perfusion decreases, triggering angiotensinogen to be released from the liver, which breaks down into angiotensin I, which triggers formation of angiotensin II when it encounters ACE in the lungs

131
Q

What is the role of angiotensin II?

A

Arterial vasoconstrictor that raises BP, triggers ventricular remodeling, and stimulates adrenal release of aldosterone

132
Q

Aldosterone and it’s mechanism of action

A

Acts at the nephron to increase sodium and water reabsorption from distal tubules to the bloodstream

133
Q

What are the net effects of the RAAS?

A

Elevated BP and BV, which leads to increased workload for left ventricle

134
Q

What problem does the RAAS create in left ventricular failure?

A

The increased BP and BV further weaken the heart muscles

135
Q

Parasympathetic nervous system effects on the heart

A

Stimulates cholinergic receptors to slow HR and decrease contraction force

136
Q

Sympathetic nervous system effect on the heart

A

Stimulates beta 1 adrenergic receptors to increase HR and contraction force

137
Q

What role does the posterior pituitary play in blood pressure and blood volume control?

A

It releases ADH, which causes water reabsorption at the nephron for increased BV and BP

138
Q

What does left ventricular diastolic dysfunction occur from?

A

Reduced relaxation or increased stiffness of ventricular muscle

139
Q

What is the common cause for development of left ventricle changes?

A

140
Q

What does left ventricular systolic dysfunction occur from?

A

141
Q

What are the two major types of consequence of left ventricle systolic dysfunction?

A

Backwards effect and forward effect

142
Q

Backward effect of left ventricular dysfunction

A

Buildup of hydrostatic pressure in the left atrium and pulmonary vasculature, leading to fluid accumulation in pulmonary interstitial/intracellular spaces (pulmonary edema)

143
Q

Forward effect of left ventricle systolic dysfunction

A

Inadequate ejection of blood into the aorta and decreased perfusion through the arterial circulatory system

144
Q

What does left ventricle systolic dysfunction stimulate?

A

RAAS, ADH release, and SNS activation

145
Q

147
Q

Right ventricular failure is also known as

A

Cor pulmonale

148
Q

Backwards failure in right ventricular failure

A

Right ventricle is weak, leading to increased pressure in right atrium, which increases systemic venous pressure, leading to edema in the body

149
Q

What is the result of increased pulmonary arterial blood flow?

A

Hypoxemia (tissue hypoxia)

150
Q

What are clinical manifestations of right ventricular failure?
