Q

How does a renin-secreting tumor of a kidney cause secondary hypertension?

A

The tumor will cause increased renin secretion which converts more angiotensinogen into angiotensin I and then II which causes more aldosterone to be released from the Zona glomerulosa leading to hypertension.

Q

How does renal artery stenosis cause secondary hypertension?

A

Atherosclerosis of the kidney will cause the macula densa to sense low kidney blood pressure (which the kidney needs to release urine). The kidneys will activate the RAAS system to increase blood pressure systemically when it it already hypertensive.

Q

What is Cushing syndrome?

A

Hypercortisolemia (increased cortisol) in the blood often as a result of increased ACTH causing an increase in aldosterone and a decrease in sex hormones

Q

What is a pheochromocytoma?

A

Adrenal medulla tumor that causes increased secretion of catecholemines such as epinephrine and norepinephrine (increased sympathetics)

20
Q

What is Von Hippl Lindow syndrome?

A

Increased secretion of catecholamines and increased sympathetics resulting in fits of anger and hypertension often caused by a pheochromocytoma or genetic defect

21
Q

How can a pheochromocytoma be tested?

A

Urine test for presence of catecholemines

22
Q

What is a symptom of all renal diseases causing secondary hypertension?

A

Oliguria, increased BUN and BV

23
Q

What effect does a pituitary adenoma secreting growth hormone have on blood pressure and how?

A

Increases blood pressure by growing the tunica media of blood vessels causing lumina narrowing

24
Q

What is Conn syndrome?

A

Primary hyperaldosteronism with normal cortisol levels and an idiopathic etiology

25
Q

What pathologies present with increased growth hormone and a pituitary adenoma resulting in secondary hypertension?

A

Gigantism and acromegaly

26
Q

How can a pituitary adenoma that causes increased TSH cause secondary hypertension?

A

Increased TSH from a pituitary adenoma can cause increased T3/T4 resulting in hyperthyroidism leading to increased blood pressure and vasoconstriction

27
Q

What pathology can be caused by increased ACTH from a pituitary adenoma?

A

Cushing syndrome

28
Q

What is Grave’s disease? How does it cause secondary hypertension?

A

Type II hypersensitivity reaction where the body creates an antibody to the TSH receptor and causes hyperactivity of the receptor and thyroid resulting in hyperthyroidism. Patient’s with Graves’ disease have increased metabolism, neural conduction, heart rate, and as a result increased blood pressure

29
Q

How does sleep apnea cause secondary hypertension?

A

A person who stops breathing at night suffers from fits of hypoxia in which the body responds with a reflexive vasoconstriction to increase blood volume to the vital organs

30
Q

What drugs can cause secondary hypertension?

A

Sympatheticohometic drugs such as cocaine and methamphetamines

31
Q

What is pre-eclampsia and how can it cause secondary hypertension?

A

Increased blood pressure during pregnancy where the placenta makes an anti-angiogenic factor so the body cannot make capillaries to compensate for an increase in blood volume resulting in increased blood pressure

32
Q

What can hypertensive heart disease lead to?

A

Heart failure
Atherosclerosis
Thrombosis
Embolism
Aneurysm
Cerebral/cognitive/retina emboli
Renal Disease

33
Q

Where will a left ventricular embolus spread to?

A

Systemic circulation

34
Q

Copper wire arterioles and Roth spots can indicate what?

A

Hypertensive left heart failure

35
Q

What are copper wire arterioles in the retina indicative of?

A

Left heart failure

36
Q

What is a Roth spot? What type of heart failure can cause this?

A

Retinal hemorrhage usually due to an embolus from left heart failure

37
Q

A Roth spot is usually due to an _______________?

A

Embolus

38
Q

What is cor pulmonale?

A

Right ventricular hypertrophy and dilation due to pulmonary hypertension

39
Q

Cor pulmonale is generally due to ________________________?

A

Pulmonary hypertension caused by a DVT throwing a saddle embolism

40
Q

Acute Cor Pulmonale is associated with what blood vessel pathology?

A

Deep vein thrombosis and pulmonary saddle embolus

41
Q

What is the main etiologic agent of acute cor pulmonale?

A

DVT causing a saddle embolus in the pulmonary artery

42
Q

What is chronic cor pulmonale primarily caused by?

A

Chronic obstructive pulmonary disease (COPD) such as chronic bronchitis or emphysema

43
Q

Chronic cor pulmonale causes both concentric and eccentric hypertrophy (TRUE/FALSE)?

A

TRUE

44
Q

Chronic cor pulmonale causes (Concentric/Eccentric) hypertrophy early on and (Concentric/Eccentric) hypertrophy in later stages?

A

Concentric, eccentric

45
Q

Chronic cor pulmonale causes (Pressure/Volume) overload early and (Pressure/Volume) overload later?

A

Pressure, volume

46
Q

A patient with chronic cor pulmonale will experience what anatomical shift in the heart?

A

Interventricular septum becomes concave to the right and the left ventricle becomes crescent like
