Cardiology Flashcards
Define cardiovascular disease
Diseases of the heart and circulation
Why is cardiovascular disease more common in children and adults in the developed world?
Due to a high prevalence of obesity
What is considered a good blood pressure?
120/80 mmHg
What is considered a high blood pressure?
140/90 mmHg
What is type hypertension is the most common?
What causes this disease?
Is it hereditary?
- Primary hypertension most common
- Multiple factors so direct cause unknown
- Can be hereditary
How can secondary hypertension occur? (4)
- Result of renal diseases
- Result of endocrine diseases (hyperthyroidism)
- Coarctation of the aorta (narrowing)
- Excessive drug/alcohol intake
Is hypertension symptomatic?
Usually asymptomatic until complications develop in target organs
Severe or prolonged hypertension increases the risk of? (4)
- Coronary artery disease
- Heart failure
- Stroke (particularly haemorrhagic)
- Renal failure
What are some complications linked with hypertension? (5)
- Arteriolosclerosis
- Narrowing of arteriolar lumen in kidney
- Increased after load leading to heart failure
- Thoracic aortic dissection
- Abdominal aortic aneurysms
How would you investigate hypertension? (4)
- BP measurements with sphygmomanometers
- Urinalysis
- Blood tests
- Electrocardiogram (ECG)
Dental Relevance of hypertension
- Patients with stable hypertension can be treated
- Hypertensive drugs can impact oral health
What Atherosclerosis?
Atherosclerosis is a disease in which plaque builds up inside your arteries
What does plaque contain? (4)
- Lipids
- Inflammatory cells
- Smooth muscle cells
- Connective tissue
What is stable plaque
Plaque that may:
- Regress
- Remain static
- Grow slowly
What is unstable plaque
Plaque which is vulnerable to spontaneous rupture, erosion or fissuring
Stable exertional angina, transient ischaemic attacks and intermittent claudication can all result due to which plaque build up?
Stable Plaque
