Outcomes
Primary outcome [1] 320904 0
Evaluation of vascular endothelial function as a change in brachia artery dilation expressed as a percentage (%).

Imaging studies, aimed at measuring the surrogate markers of atherosclerosis, were also completed using an ultrasonograph (Sequoia 512, Mountain View, Ca, USA) with a 6 MHz linear transducer. The measurements of flow-mediated dilation (FMD) of brachial artery in response to reactive hyperemia were evaluated non-invasively, in compliance with the ultrasound method described by Celermajer (Celermajer DS, Sorensen KE, Gooch VM, Spiegelhalter DJ, Miller OI, Sullivan ID, et al. Non-invasive detection of endothelial dysfunction in children and adults at risk of atherosclerosis. Lancet. 1992;340:1111-1115).

Secondary outcome [1] 373304 0
Evaluation of vascular remodeling of carotid IMT expressed in mm.
Imaging studies, aimed at measuring the surrogate markers of atherosclerosis, were also completed using an ultrasonograph (Sequoia 512, Mountain View, Ca, USA) with a 6 MHz linear transducer.
IMT measurements of the distal wall of the carotid artery were taken in three locations: i.e. 1. common carotid artery (2 cm below the bulb), 2. carotid artery bulb, and 3. proximal internal carotid artery. The final IMT value was the mean from all measurements on both carotid arteries.

Summary
Brief summary
Treatment with statins and fibrates improves endothelial function.
Assessment of the effect of pharmacotherapy (statin or fibrates) on the diastolic response of the brachial artery, the carotid artery IMT and the concentration of pro-inflammatory, thrombotic and oxidative stress markers in subjects with dyslipidemia.
We plan to include 200 police officers in the study, of which 50 will be treated with a statin (20 mg/day) and 50 subjects treated with fenofibrate (215 mg/day) for 24 months.
The results of the study may broaden the knowledge about the increased progression of atherosclerosis in the group to be exposed to more stressors.
