Q

what is the difference between a embolic stroke and a thrombotic stroke?

A

embolic stroke

  • caused by emboli, blood clots that travel to brain blood vessels
  • 25% related to atrial fibrilation

thrombotic stroke

  • often develops when thrombus breaks away and causes and blockage

25
what is high blood pressure? what happens when you develop high blood pressure?
- too much force/pressure on artery walls - strains, weakens, enlarges heart - scars and hardens arteries - increases risk of heart attack, stroke, atherosclerosis, and kidney failure
26
what is cholesterol? what is important for? where can it be obtained?
- fatty, wax-like substance - important component of cell membranes, sex hormones, vitamin D, and protective nerve sheaths - obtained from food or made by liver
27
how is cholesterol carried in the blood?
protein-fat packages called lipoproteins
28
what are low-density lipoproteins?
- "bad cholesterol" | - transports cholesterol to organs and tissues
29
what are high-density lipoproteins?
- transports cholesterol out of arteries and back to liver | - helps protect against heart disease by removing cholesterol from blood vessels
30
how can we increase HDL and decrease LDL?
exercising
31
what are 3 ways we can improve cholesterol levels?
1. choose unsaturated fats instead of saturated and trans fats 2. exercise regularly 3. increase omega 6 and 3 oils
32
what are 4 things that excess body fat may contribute to?
1. high blood pressure 2. elevated cholesterol levels 3. diabetes 4. narrowing of coronary arteries
33
what are the BMI ranges?
underweight: < 18.5 normal: 18.5-24.9 overweight: 25.0-29.9 obese: > 30.0
34
what happens when there is increased blood glucose?
- damages lining of arteries - increases blood levels of glucose - linked to other CVD risk factors
35
what are triglycerides?
blood fats obtained from food and manufactured by the body
36
what are 5 psychological and social factors that contribute to CVD?
1. stress 2. chronic hostility and anger 3. suppressing psychological distress 4. depression and anxiety 5. social isolation
37
what are 4 non-modifiable risk factors for cardiovascular disease?
1. family history (DNA) 2. age 3. sex 4. ethnicity

39
what is an oncogene? what is it involved in?
- a gene that can mutate and replicate | - involved in transformation of a normal cell into cancer cell
40
what is a tumor suppressor gene?
a gene that controls the development of oncogenes
41
what is metastasis?
spread of cancer cells from one part of body to another
