Q

What is HDL?

A

HDL stands for High-Density Lipoprotein. It is often referred to as “good” cholesterol because it helps remove excess cholesterol from the bloodstream and transport it to the liver for excretion.

Q

What is LDL?

A

LDL stands for Low-Density Lipoprotein. It is often referred to as “bad” cholesterol because they transport cholesterol to organs and tissues

Q

Whys is smoking cigarettes bad?

6

A
  • Reduces Level of HDL (increased cholesterol)
  • Increases Level of LDL and Triglycerides
  • Includes Carconigens and Toxis (damages DNA)
  • Nicotine (increases BP and hardens arteries)
  • Increased Platelet Adhesion
  • Carbon Monoxide Intake harms O2 delivery to tissues

Q

Smoking

What can increased Nicotine consumption lead to?

A
  • Hardened arteries and increased blood pressure
  • Lung Cancer
  • O2 saturation goes down, HR + BP go up -> Heart Attack

Q

What is High blood pressure (hypertension)?

A

Too much force or pressure exerted against artery walls
– Strains, weakens, and enlarges the heart
– Scars and hardens arteries
– Increases risk of heart attacks, strokes, atherosclerosis, and kidney failure

Q

What is Cholesterol?

A

Cholesterol: lipid,fatty, wax-like substance
- Essential for proper body functioning
- Carried in the blood—to and from the liver—in lipoproteins
form (LDL or HDL) or chylomicrons

18
Q

Where do we get cholesterol from?

A

Obtained from food (fat intake, exogenous) as well as the
liver which manufactures it (endogenous/de novo).

19
Q

How does activity effect cholesterol levels?

A

HDL levels increase with exercise

LDL and TGs levels decrease with exercise

20
Q

What are Risk factors of high cholesterol

A
  • age (men 45 yrs and older, women 55 yrs and older)
  • Smoker
  • High blood pressure
  • HDL <40 mg/dL or 1.5mmol/L
  • Familial hypercholesterolemia: decreased removal of LDL, accumulation in vessels = premature atherosclerosis
21
Q

What HDL levels are considered a risk factor?

A

<40 mg/dL or 1.5mmol/L

22
Q

TOTAL Cholesterol Guidelines

A
23
Q

HDL Cholesterol Guidelines
(good cholesterol)

A
24
Q

LDL Cholesterol Guidelines
(bad cholesterol)

A
25
Q

Triglycerides Cholesterol Guidelines

A
26
Q

How do we calculate Total cholesterol?

A

Total cholesterol = TG + HDL +LDL

27
Q

What ratio of LDL/HDL would be considered Low Risk?

What ratio of HDL/LDL would be considered Low Risk?

What about Total Cholesterol/HDL?

A

Less than 3.3-4.4

Less than 0.22-0.3

Less than 4, preferable 2-3

28
Q

How can one improve cholesterol levels through food intake?

A
  • Choose unsaturated fats over saturated and trans fats
  • Increase soluble fibre intake
  • eat more fruits and vegetables
  • Lower Omega 6s (chicken, pork, beef and canola oil/corn) and increase Omega 3s (olive oil, fish, soy): you want a low 6/3 ratio
29
Q

What food increase HDL?

A

Unsaturated fats increase HDL: olive oil, nuts, seeds, oats, fatty fish, avocados

30
Q

How does excersize reduce risk factors?

A
  • Decreases BP by 4-9mmHg
  • Decreases triglycerides (use to produce ATP)
  • Increases HDL levels
  • Helps people maintain a healthy weight: burns calories
  • Helps prevent or control diabetes (raises insulin sensitivity, lowers sugar levels):
31
Q
A

Fat that collects in the torso (“apple” shape, central
obesity) is more dangerous than fat that collects around
the hips (“pear” shape) due to greater inflammation

32
Q

What does Excess body fat contribute to?

A

– High blood pressure
– Elevated cholesterol levels
– Diabetes
– Narrowing of coronary arteries and arythmias

33
Q

What is Diabetes?

A

disruption of glucose metabolism
– Damages the lining of arteries: increases ischemia
– Increases blood levels of glucose
– Linked to other CVD risk factors

34
Q

Why is increased Alcohol Consumptio bad?

A

Consumption of alcohol can affect blood pressure by increasing the activity of renin, a hormone involved in blood pressure regulation. Alcohol can also lead to water retention, which can further increase blood pressure, especially when consumed in excess.

35
Q

What are ideal Waist-to-height ratios?

A

0.53 for women and at a ratio of 0.55 for men. (cm or inches)

Men should have a waist about 55% of their height, and women about 53%

36
Q

Ideal BMI Range
(units is kg/m^2)

A

18.5 - 24.9

37
Q

What BMI is considered Underweight?

A

Below 18.5

38
Q

What BMI is considered Overweight?

A

25.0 - 29.9

39
Q

What BMI is considered Obese?

A

30.0 and Above

40
Q

What is the ideal Waist-Hip ratio in women?

A
41
Q

What is the ideal Waist-Hip ratio in men?

A
42
Q

What is the ideal body shape?

A

hip and bust measurements nearly equal in size, with a narrower waist

43
Q
A
44
Q

What are the Main Cardiovascular Disease (5 types)

A
  • Hypertension
  • Atherosclerosis
  • Heart disease and attacks
  • Stroke
  • Congestive heart failure
