> 190
what is the primary contributor to hypercholesterolemia?
LDL cholesterol

mediterranean diet-fish, nuts, olive oil, high fiber low fat
avoid high saturated fat-have lean protein
5 servings fruits/vegetables in day

lack of knowledge, convenince
what is the best way to make sure pts stick to new healthy diet?
set up regular and frequent contacts, chek in with pts regularly by person or phone, refer to nutritionist or diet group or exercise program, help pt set realistic goals, do not have to achieve ideal body weight-even small amount of loss is good,
give them positive reinforcement, stick with them
what is the metabolic syndrome?
cluster of risk factors
secondary treatment target after lowering LDL, smoking increases risk of CHD in people with metabolic syndrome
what are the three things we can tell pts to focus on with metabolic syndrome?
diet
exercise
lipid medication
what are the major classes of hyperlipidemia medication and how do they each work?
statins: affect cholesterol production to lower LDL and triglycerides and increase LDL receptor production, first line of treatment in pts with high LDL
niacin: lower triglyceride and increase HDL, first line in pts with high triglycerides, most potent in terms of raising HDL
cholesterol absorption inhibitors: reduce absorption of dietary cholesterol and block reabsorption of cholesterol secreted in the bile, lower LDL
what are good cholesterol food groups?
oat bran, psyllium, nuts and soy products
how common is familial hyperchoelsterolemia?
1/500 americans have it
20% have a heart event by age 30
what should be done when a high risk familial hypercholesterolemic pt is identified?
all family members should be screened, including children
What is a rare side effect of statin? what can be done if a pt is having these symptoms?
muscle aches-(also can be due to diuretics) check
myaligias and arthraligia will reverse with lower dose
-alleviate by:
-lower dose and add ezetimide or bile acid resin
-dietary supplement: sterol marginine, nuts dietary fiber
-switch to another statin
-bile acid reabsorption blocker
what can make hypertriglyceridemia worse?
hormone replacement therapy (can also increase risk of cancer)
what is gemfirbrizil?
a fibric acid
thers-fenofibrate, clofibrate
What are the summary points from the ACC/AHA 2013 guidelines?
- there is no evidence to support titrating statins to reach a specific LDL
- 4 subgroups of patients benefit from a fixed dose, high intensity statin therapy, but do not beenfit from targeting a depcific therapy (CD< LDL>190, DM1 and DM2 40-75 with LDL, 10 year CVD risk >7.5%),
- there is insufficient evidence for or against statin in three subgroups: age 75+ (unless CVD), need for hemodialysis, NYHA class II, III IV heart failure
- there is no evidence base to recommend any treatment for cholesterol other than statins
