Q

The 2013 ACC/AHA Guideline Key Points?

A
  1. Encourage adherence of a heart healthy lifestyle
  2. Statins are recommended for adults in groups demonstrated to benefit
  3. Engage in Clinic patient discussion before initiating statin therapy
  4. Initiate the appropriate intensity of statin therapy to reduce ASCVD risk
  5. Used Pooled cohort equation for estimating 10-ASCVD risk
  6. Evidence is inadequate to support specific LDL ot non HDL goals
  7. Nonstatin drug therapy may be considered in selected individuals

Q

Summary of statin initiation recommendation to Reduce ASCVD risk

Is the patient older than 21 and have ASCVD?

If so is the patient older than 75?

A

if older than 21 and less than 75 initiate high-intensity statin therapy

Patient is greater than 75 or not a canidate for High-intensity initiate moderate intensity

Q

Summary of statin initiation recommendation to Reduce ASCVD risk

Does the patient not have ASCVD?

A

Then if patient has a LDL >=190 initiate high intensity therpay

If it is not that high but the patient has DM with an LDL 70-189 age 40-75 Initiate moderate statin

But if the patient calculated risk is >=7.5% then initiate high intensity therapy

Q

Summary of statin initiation recommendation to Reduce ASCVD risk

If the patient does not fit initial criteria move to primary prevention

A

If patient if patient has LDL 70-189 and not receiving statin therpay

Calculate their 10 year risk factor

If >= 7.5% Moderate to High intenesity

5-less than 7.5 Moderate intensity

But during this time Clinicial-patient discussion must be made to decide if statin is the best choice for the patient. If no Encourage healthy lifestyle and manage other risk factors

IF yes to statin do the same and initiate appropriate statin intensity.
