A case -based approach was used to confer on this very relevant subject. Three case scenarios  were discusssed. Treat to target has the most widely used strategy in the past 15 years, but there are  3 problems with this approach. The current clinical trial data do not indicate what the target should be.

It does not take into account potential adverse effects from multidrug therapy that might be needed to achieve a specific goal. Rather than LDL-C or non HDl-C targets, the 2013 ACC/AHA guideline used the intensity of statin therapy as the goal of tratment.
