Q

How does elevated insulin increase dyslipidemia?

A

Q

Which of the following statements accurately describes the relationship between inflammation and the generation of interleukin‐6 (IL‐6) during exercise?

A

The more muscle used, the greater the release of the anti‐inflammatory myokine IL‐6.

19
Q

Which pharmacologic interventions are most likely to deplete CoQ10?

A

Statins and beta‐blockers

20
Q

Niacin should be used with caution in which group of patients?

A

Patients with diabetes mellitus type 2.

21
Q

Which of the following is most likely to stimulate NF‐kappaB production?

A

Lipopolysaccharides

22
Q

Which of the following is correct regarding the relationship between leptin and obesity?

A

Obese patients likely have elevated leptin.

23
Q

what is the proposed mechanism of berberine?

A

increasing insulin receptor expression, microbiome effects

24
Q

which of the following effects of hyperinsulinemia is the most relevant to cardiometabolic risk?

A

increasing hsCRP - it is pro-inflammatory

25
Q

relevance of genetic markers of CVD?

A 
MTHFR (homocysteine, cofactors riboflavin and niacin), ApoE (diet),
familial hypercholesterolemia (treat)
26
Q

what food groups should be emphasized in patients with HTN?

A

(Cardiometabolic food plan emphasis) lycopene, arginine, dietary fiber. NOT on this list if sulfur/brassicas which are on the detox food plan instead. condition specific phytonutrients. review food plan wheels.

27
Q

what are foods to include in HTN?

A

soy, whey, legumes (plant fiber), cold water fish (EFA), L-arginine containing (nitric. oxide), cocoa, lycopene (antioxidant)

28
Q

What is the relationship between heart rate variability and sympathetic tone?

A

inverse: high HRV, low tone, low risk

low HRV, high tone, high risk

29
Q

what are the HR exercise intensity cut offs?

A

low 50-63% mod 64-76% high 77-93% (max 220 - age)

30
Q

what are the recommended dietary changes for ApoE3 and ApoE4?

A

low fat, low alcohol, fish oil

31
Q

Your 25‐year‐old college‐aged patient tells you his dad just had a heart attack at the age of 48. Your patient is known to carry homozygous ApoE 4/4 mutation. Accurate advice about his lifestyle includes:

A

Encouraging avoidance of alcohol and implementing a low‐fat diet plan to improve lipid profile and reduce cardiovascular risk.

32
Q

Your 47‐year‐old patient asks how you know she is heading toward insulin resistance (prediabetes) simply by looking at her advanced lipid profile, even though her fasting glucose levels are only 85 mg/dl. Her results would most likely look like:

A

Normal LDL‐C, elevated LDL‐particle #, low HDL2b, elevated large‐sized VLDL.

33
Q

In discussing dipping vs. non‐dipping nocturnal blood pressure concerns with your 50‐year‐old female school teacher patient with stage 1 hypertension, you explain:

A

Patients classified as non‐dippers are at an increased risk for multiple forms of cardiovascular disease

34
Q

Your patient is a 62‐year‐old female with tender lumps on the distal interphalangeal joints of her fingers. On examination, you note that she has seborrheic dermatitis around her scalp. Which of the following nutrient deficiencies might explain these findings?

A

Vitamin B6

35
Q

On which of the following biomarkers does insulin resistance have a direct effect?

A

It increases small, dense LDL particles

36
Q

Which of the following is the most useful marker in assessing levels of oxidative damage to DNA?

A

8-hydroxydeoxyguanosine

37
Q

What biomarker is associated with rupture-prone plaque?

A

Myeloperoxidase

38
Q

Which of the following would be most effective in reducing risk of cardiovascular disease

A

Reducing oxidized LDL and high sensitivity C-reactive protein (hs-CRP)

39
Q

A 56-year-old male presents to your office with a five-year history of diabetes. He has recently had a hemoglobin A1c, which was elevated at 8.2. He reports tingling in both feet and on physical exam shows a loss of vibratory sensation in his toes. What supplemental nutritional intervention would you suggest?

A

High dose lipoic acid and methylcobalamin

40
Q

What aspects of exercise should an “exercise prescription” address?

A

Frequency, duration, and intensity

41
Q

The following is true regarding HMG-CoA reductase:

A

It is stimulated by leptin and insulin and suppressed by internalization of LDL.

42
Q

A

CoQ10 and taurine

43
Q

Which of the following dietary recommendations is associated with decreased LDL, increased HDL, and decreased triglycerides?

A

Mediterranean diet
