Summary

Cardiovascular disease (CVD) is the number one cause of mortality for men and women in the United States. Dyslipidemia, particularly a high low-density-lipoprotein cholesterol (LDL-C) level, is a well-established cardiovascular risk factor and the current American Heart Association guideline for CVD risk assessment recommends a lipid panel to be checked. In addition, guidelines recommend statin therapy in all patients with clinical atherosclerotic CVD, all patients with LDL-C = 190 mg/dL, patients age 40-75 years with diabetes and LDL-C 70-189 mg/dL, and patients with an estimated 10-year atherosclerotic CVD risk = 7.5%. For all of these patients, a fasting lipid panel should be drawn prior to statin initiation as well as during follow-up to assess medication and lifestyle adherence. These fasting lipid panels are obtained via conventional phlebotomy via venopuncture in an office-based or hospital laboratory setting. However, research protein quantitation with mass spectrometry and enzyme-linked immunosorbent assay (ELISA) are technologies that allow for sensitive quantitation of protein biomarkers and targets, including lipoproteins. Most importantly, multiple reaction monitoring (MRM) mass spectrometry is able to assess samples from a dried blood spot (DBS), whose advantages include minimal volume requirements, ease of sample attainment by finger stick with minimal training required, ease of transport, and sample stability.

The purpose of the proposed analysis is to 1) measure changes in CVD biomarkers before and after initiation of statin therapy and 2) compare lipid measurements by conventional phlebotomy blood samples to research protein quantitation measurements in DBS and plasma.

OTHER

Dried blood spot testing and phlebotomy

At baseline and 4-6 week follow-up, a phlebotomy serum sample (5 ml) will be collected in one golden-top tube for clinical laboratory measurement of cholesterol (total cholesterol, LDL-C, triglycerides, HDL-C) . During the same phlebotomy, a fingerprick dried blood spot (DBS) sample and two lavender EDTA plasma tubes (5 ml each) will be collected for analysis of CVD protein markers
