Q

Describe the progression of cardiovascular heart disease starting from normal arterial structure?

A
  1. Atherosclerosis: takes decades to build up and block blood vessels with fat
  2. Thrombosis: Plaques split and join together elsewhere
  3. Myocardial Infarction: normally heart attack
  4. Arrhythmia: abnormal heart beat
  5. Death

Q

Hypertension is a major risk factor for cardiovascular disease, describe what it can lead to?

A
  1. Risk factor for stroke and coronary heart disease
  2. Can lead to atherosclerosis through damaging of endothelial cells
  3. Damage to the kidneys
  4. Lead to left ventricular hypertrophy, pulmonary oedema and congestive heart failure

Q

How can you tell you have hypertension, and when does it primarily occur?

A
  1. Asymptomatic a lot of the time
  2. Primarily occurs in men 35 to 50
  3. Happens to women normally after the menopause

Q

What are the causes of secondary hypertension?

A
  1. Adrenal gland syndrom: hyperaldosterone (Crohn’s syndrome), Cushing’s syndrome (overproduction of corticosteroid hormones)
  2. Kidney diseases: polycystic disease, kidney tumour or failure
  3. Drugs: anti-inflammatory (prednisone), birth control pills (oestrogen), cold medicines (psuedoephedrine, phenylephrine)

Q

What is the treatment strategy for patients with hypertension who are under 55?

A
  1. (A) ACE inhibitor or angiotensin II receptor blocker (ARB) 18
  2. (A) + (C) Calcium channel blocker (CCB)19
  3. (A) + (C) + (D) Thiazide like diuretics
  4. Resistant hypertension: (A) + (C) + (D) and consider further diuretic therapy, alpha or beta blocker or expert advice

Q

What is the treatment strategy for patients with hypertension who are afro Caribbean or over the age of 55?

A
  1. (C) Calcium channel blocker (CCB)19
  2. (C) + (A) ACE inhibitor or angiotensin II receptor blocker (ARB) 18
  3. (A) + (C) + (D) Thiazide like diuretics
  4. Resistant hypertension: (A) + (C) + (D) and consider further diuretic therapy, alpha or beta blocker or expert advice
17
Q

How do you work out blood pressure?

A

Cardiovascular output (CO) x Total Peripheral Resistance (TPR)

18
Q

What are the four factors of regulation of blood pressure?

A
  1. Blood volume
  2. Blood viscosity
  3. Cardiovascular output (CO)
  4. Total Peripheral Resistance (TPR)
19
Q

Where is blood pressure usually measured in terms of resistance vessels? And what does this show?

A
  1. Where the largest pressure drop is and the transfer between arteries and arterioles into the veins
  2. Contractile force has a large impact on the blood pressure
20
Q

Describe the process of how the body maintains normal blood pressure range after receiving a stimulus to increase blood pressure?

A
  1. Arterial blood pressures goes over the normal range
  2. Baroreceptors in the aortic arch and carotid sinuses stimulate
  3. Impulse travels along afferent nerves from the baroreceptors
  4. Stimulate cardio-inhibitory centre
  5. Leads to sympathetic impulses decreasing and decrease in heart rate/ contractility
  6. Rate of vasomotor impulses allow vasodilation which increases diameter
  7. Leads to decrease in cardiac output and resistance which leads body back to normal blood pressure

(the opposite of this if there’s stimulus that decreases blood pressure)
