Outcome measures
Primary outcome
The number of patients that reach the set treatment target of LDL-C <2.5 mmol/l when using non-fasting blood samples while their fasting LDL is>2.5mmol/l.
Secondary outcome
-The number of patients that reach the set treatment target of apo B <0.8 g/l when using non-fasting blood samples and do not reach the target in fasting blood samples.
-The number of patients who reach the set treatment target of non-HDL-C<3.3mmol/l when using non-fasting blood samples and do not reach the target in fasting blood samples.
-Differences in morning and afternoon LDL-C levels.
-Absolute differences in fasting and non-fasting LDL-C, direct LDL-C, apo B, non-HDL-C and triglycerides.
-Absolute differences between calculated LDL-C, direct LDL-C and LDL-C using ultracentrifuge in relation to the triglyceride concentrations.
-Construction of ROC curves to determine optimal normal values for non-fasting LDL-C.
Background summary
Background: Current guidelines recommend to measure the lipid profile in the fasting state although evidence is growing that a non-fasting lipid profile is sufficient most of the time and more convenient for both physicians and patients. However, comparisons between the absolute difference in fasting and non-fasting lipid profiles within individuals is lacking. Therefore, it is unknown whether current lipid treatment targets are suitable when using non-fasting lipid profiles.
Objective: To investigate whether a non-fasting lipid profile is as accurate and of equal clinical value as a fasting lipid profile for guiding lipid lowering therapy for secondary cardiovascular risk reduction.
Study design: Open randomized, cross-over trial where subjects are randomized between first measuring a fasting lipid profile followed by a non-fasting lipid profile on a separate day or vice versa.
Study population: Patients on lipid lowering therapy as secondary prevention for cardiovascular disease.
Main study endpoint: The number of re-classified patients that reach the treatment target of LDL-C <2.5 mmol/l when using non-fasting blood samples while their fasting LDL is >2.5mmol/l.
Risks, burden and benefits on participation: No major risks are involved besides a hematoma from the venipunctures or hypoglycemia due to fasting. Subjects need to visit the hospital two times, once fasting and, on another day, any time the subjects wish. During the two measurements it is not allowed to change lipid lowering therapy. Subjects receive an expense allowance of 10 euro’s upon participation. The potential benefit of the study is to demonstrate that a non-fasting lipid profile is accurate enough in comparison to a fasting lipid profile, which will ease the measurement of lipid levels for a large patient population worldwide.
Study objective
Current treatment targets for LDL-C, non-HDL-C and apo B can be used as accurately in the non-fasting state as in the fasting state. The measurement of LDL-C, non-HDL-C and apo B in the non-fasting state does not confer to an increased risk of falsely reaching the recommended treatment target.
Study design
Not-applicable
Intervention
Open randomized, cross-over trial where subjects are randomized between first measuring a fasting lipid profile followed by a non-fasting lipid profile on a separate day or vice versa.

Inclusion criteria
Male and female patients, aged 18 years or older, from the outpatient department of Cardiology and Internal Medicine receiving lipid lowering therapy as secondary cardiovascular prevention are suitable for inclusion. Lipid lowering therapy is defined as the use of statins, fibrates, ezetimibe or nicotinic acid or a combination of these
Exclusion criteria
A change in lipid lowering therapy within the last 4 weeks is an exclusion criterium for study participation.
