There is one clinical trial.
Subclinical atherosclerosis is the atherosclerotic process identified before clinical symptoms and thus it can be a useful marker of future cardiovascular events. It can be evaluated by many methods. This study included the diagnosis of subclincal atherosclerosis by four different methods: coronary calcium score, carotid doppler ultrasound to quantify intima media thickness and carotid plaques, exercise stress test and ankle brachial index. Clinical data, anthropometric measures (body mass index, abdominal circumference), markers of inflammation (high sensitive - C reactive protein, TNF alfa and Lipoprotein Associated Phospholipase A2), fat tissue function (leptin, resistin and adiponectin), glucose metabolism (fasting plasma glucose, glycated hemoglobin and insulin) and genetics markers of atherosclerotic process were evaluated as biomarkers of subclinical atherosclerosis in a uneventful population.
Genotyping of DNA at the following rs2383206, rs10757274, rs10757278, rs1051931, rs16874954 and rs1799724 and RNA of PLA2G7 (2-ΔCT), TNF-α (2-ΔCT), LEP (2-ΔCT), LEPR (2-ΔCT).
Blood sample was also stored for DNA (rs2383206, rs10757274, rs10757278, rs1051931, rs16874954 and rs1799724) and RNA PLA2G7 (2-ΔCT), TNF-α (2-ΔCT), LEP (2-ΔCT), LEPR (2-ΔCT) extraction and analyses.
