Q

are there symptoms that a patient can watch out for to see if they have high cholesterol?

A

NO - not generally

if the pt has familial hypercholesteromemia – may get xanthomas – like bumps on the skin that contain lipids

also, may get pancreatitis, but only if TG levels are over 500mg/dL

A

generally - every 4-6 years

but if the patient has a history of heart disease or diabetes, or if family history – want to check more frequently – starting at 20 years old

Q

as mentioned, LDL is actually a calculated value using a formula

when would this formula not work?

A

it wouldnt work if triglycerides are over 400mg/dL

in this case, a direct LDL would have to be ordered (expensive!)

Q

triglycerides should be less than….

A

150mg/dL

but high triglycerides really arent high risk for ASCVD unless also paired with high LDL/low HDL

also, over 500 is pancreatitis concern

Q

a patient’s triglyceride levels come back as 168.

is this a concern? would we ask any follow up questions?

A

really not a concern. normal is less than 150. generally only a concern if very high

also, ask if the patient had a fatty meal before bloodwork, bc this can cause the TG to spike – ask to follow up in a couple days if she did have fatty meal

25
true or false atypical antipsychotics can increase cholesterol and TG
true
26
if pharmacotherapy is needed to lower LDL (lifestyle modifications alone is not enough), which drugs are 1st line and why?
statins bc they are proven to significantly reduce morbidity and mortality in both primary (no ASCVD yet) and secondary (have ASCVD)prevention
27
as mentioned, eating healthy can help to decrease cholesterol name some foods to recommend to a patient to do this
fruits, vegetables, whole grains fish, poultry (no skin), low-fat dairy legumes, non-tropical oils, nuts
28
name some foods to LIMIT if a patient has high cholesterol
saturated and trans fat sweets and sugar-sweetened drinks red meats
29
true or false if a patient is trying to lower their LDL, they should try to eat a lot of red meat
FALSE - they should limit it have poultry without the skin instead
30
name 2 foods to consider recommending to a patient to lower LDL
plant sterols/stanols (yogurt, protein bars) viscous fibers (fruit, vegetables, supplements)
31
3 classes of lifestyle modifications to recommend to a patient to lower LDL cholesterol
physical activity weight loss stop smoking
32
true or false quitting smoking cannot help to decrease LDL cholesterol
FALSE - it can -- also significantly lowers risk of ASCVD
33
weight control can be recommended to a patient who has high cholesterol how much should they lose?
for overweight and obese patients - even a 5% weight loss can really lower risk of ASCVD, even if they are still overweight after losing this amount
34
explain the exercise that should be recommended to a patient who has high LDL
aerobic activity 3-4x a week 40 mins at least of moderate-vigorous exercise -- just walking isn't enough
35
what BMI is a patient considered overweight/obese
overweight - over 25 obese - over 30
36
name 5 scenarios in which a statin is basically immediately initiated (as long as no contraindications)
-if 0-19 and has familial hypercholesterolemia -if 40-75 with diabetes (even is LDL is good!) moderate intensity usually - but consider high intensity if risk factors -if LDL 190 or more - automatic high intensity -if ASCVD is 20% or more - auto statin (high intensity) -if ASCVD is 7.5-19% (intermediate risk) - initiate mod intensity
37
name the 4 "risk" categories for the ASCVD score that are used to determine if statins should be started
less than 5% is low risk 5%-less than 7.5 is borderline risk 7.5%-19% is intermediate risk 20% or more is high risk
38
2 conditions SPECIFIC TO WOMEN that are an example of a risk enhancer when determining if a patient should be given a statin
preeclampsia or premature menopause
39
true or false persistently high triglycerides over 175 is considered a risk enhancer for being on a statin
true -- combo of high TG and high LDL is bad
40
patient's ASCVD score is 3% has a family history of early MI LDL is 133 should a statin be started?
NO LDL is not 190 or more ASCVD is low risk just emphasize lifestyle modifications if she was in the borderline risk category, could potentially consider starting - but still not automatic
41
patient has diabetes and is 62 years old LDL is 152 ASCVD is 31.9% should he be started on a statin?
YES - just 40-74 and having diabetes is enough to be on a statin, not to mention that LDL is already high high intensity statin should be given due to ASCVD score and other conditions
42
name the only 2 high intensity statins
atorvastatin 40-80mg rosuvastatin 20-40mg
43
name the 4 low intensity statins (and their doses) what is important to note about them?
simvastatin 10mg pravastatin 10-20mg lovastatin 20mg fluvastatin 20-40mg they really aren't used anymore. dont lower LDL much and also not shown to affect morbidity and mortality outcomes
44
which statin is considered the "gentler statin" and why
pravastatin bc it's not metabolized by 3A4, and has less potential for adverse effects of myopathy
45
HIV regimen is important to consider when giving statins, because there are many drug-drug interactions why else are HIV regimens a consideration?
because HIV drugs increase cholesterol however, there's really nothing we can do about the regimen bc patients need to be on it for life
46
_______ is the HIV drug that should be avoided with atorvastatin
atazanavir
47
What are the 3 statins that are RECOMMENDED with cobicistat or ritonavir boosted HIV therapy? what doses and why?
pitavastatin 4mg atorvastatin 20mg rosuvastatin 10mg "PAR" even if the HIV patient, in theory, needs a high intensity statin, these moderate doses are still used because they will be "boosted" and act as high intensity
48
which 2 statins should definitely be AVOIDED in HIV boosted regiments (cobicistat or ritonavir)
simvastatin and lovastatin
49
true or false rosuvastatin is less likely to have drug-drug interactions than atorvastatin
TRUE - not metabolized by CYP3A4
50
name 5 contraindications to statins
-pregnant or breastfeeding -active liver disease -excessive alc -unexplained and persistent LFT 3x over ULN (upper normal limit) -CPK over 3x ULN
51
how often do we check LFT (liver function tests) in a statin patient?
only get the baseline level, and only check again if the patient has symptoms
52
why is CPK over 3x the ULN a contraindication for statins?
because this is a clear sign of myopathy, and can progress to life threatening rhabdomyolysis
53
true or false statins do not affect the liver
FALSE - they can cause hepatotoxicity active liver disease is thus a contraindication! and LFT 3x over the ULN is also a CI
54
name 3 AE in statins
headache (only when 1st start - goes away) increased LFT (rare) myalgia (can progress to rhabdo)
55
true or false when a patient is on a statin, routine checking for increased LFT is recommended
FALSE - baseline is gotten, and then only checked again if the patient is symptomatic if LFT is over 3x ULN at this point, it is a contraindication and the statin needs to be discontinued
56
"SAMS" who is most at risk?
statin-associated muscle symptoms women, asians, and elderly are at increased risk
57
explain the outline of what to do if a patient experiences new or worsening muscle pain on a statin
-give the questionnaire, get CK level -if the patient's symptoms are intolerable, OR if CK level is over 3x over baseline, stop stain for 2-4 weeks/2 months if their symptoms IMPROVE - review the meds and d/c any statin interactions. start a different statin at LOWEST RECOMMENDED DOSE. give same statin that is tolerated by other fam members if possible. if the patient's symptoms come back even on this new statin - try non daily dosing with ros. or atorv 1-2 times a week (after 2-4 weeks of witholding). if their symptoms STILL COME BACK - they can't tolerate statin. give zetia or bile acid agent or both (after 2-4 week washout) if their symptoms DO NOT IMPROVE when initial statin removed- see if other cause
58
do statins cause diabetes?
short answer - no shown to increase the risk by around 9%, but these trialed patients were already on the brink of diabetes. mechanism - statins increase insulin resistance
59
are statins used in patients over 75?
yes - benefits have been shown in both primary and secondary prevention if the benefits outweigh risks, we can start moderate-high intensity statin. important to note that statins really only start to show benefit after taking for 5 years -- do we think the patient will even live that long?
60
2 safety concerns of giving statins to older patients over 75
more likely to get myopathies and rhabdo some case reports show a concern of cognitive or dementia risk
61
true or false it is not important to take statins every day
FALSE - it is
62
true or false all statins must be taken at bedtime
false - all except atorvastatin and rosuvastatin (have long half life)
63
counseling about grapefruit/grapefruit juice with statins
patients can have 1-2 cups of juice per week on atorvastatin if they really want to grapefruit itself is probably okay
64
explain how often to monitor LDL for a statin patient
baseline (obviously) then 4-12 weeks after initiating the drug or increasing the dose if the goal is achieved, only monitor every 3-12 months. if not achieved after 4-12 weeks, consider increasing dose or adding on
65
true or false the efficacy of statins is based on the LDL
true
66
name the LDL goal for: -non-ASCVD patients -ASCVD patients or VERY HIGH RISK -ASCVD patients with diabetes
non-ASCVD - LDL less than 100 ASCVD or high risk - LDL less than 70 ASCVD + diabetes - LDL less than 55
67
true or false diabetes is considered a "very high risk" for ASCVD and automatically puts a patient into the less than 70 LDL goal
true if they have ASCVD on top of it, then goal is less than 55
68
true or false we do not want LDL to go too low
FALSE -- recent data shows there is no concern with hemorrhage, cancer risk, depression, diabetes, etc
