Researchers from Uppsala University have unveiled an innovative instrument that can simultaneously measure 21 biomarkers linked with cardiovascular disease with remarkable precision. This ground-breaking development was published in the renowned scientific journal PLOS One, and it carries significant implications for patient care, especially in the realm of preventive health testing. Enhancing Predictive Power with Biomarkers The newly developed tool provides a more nuanced and predictive analysis of cardiovascular complications and disease prognosis using a simple blood test. It could essentially aid in personalizing disease treatment for patients as well as in monitoring treatment effects more effectively. Measuring Biomarkers with Proximity Extension Assay (PEA) The instrument relies on the analysis of 368 blood proteins, using samples derived from over 10,000 patients who have taken part in international studies on novel cardiovascular disease treatment methods, thereby identifying 21 circulating proteins (CVD-21 panel) as potential biomarkers. These biomarkers are indicative of functional disturbances that influence cardiovascular disease development and the risks and benefits of various treatments. The Proximity Extension Assay (PEA), a molecular biology technology developed in Uppsala, is used in the CVD-21 instrument to measure protein content even at extremely low concentrations. Furthermore, the analysis requires only a small volume of blood plasma, making the test less invasive for patients. Unveiling New Biomarkers & Shaping Personalized Treatment Plans While tested on 4,224 patients with chronic coronary disease, the CVD-21 instrument, coupled with the protein troponin T, performed comparably well to current risk markers for cardiovascular disease. Additionally, nine new biomarkers with predictive significance for various cardiovascular complications like myocardial infarction, cardiovascular death and heart failure hospitalisation were identified through this instrument. These biomarkers could not only enrich our understanding of cardiovascular disease causes, but also refine the assessment of patient risk, which currently relies mostly on clinical variables. The researcher team at Uppsala University firmly believes that this biomarker-based instrument can provide detailed information about numerous proteins simultaneously and consequently, reveal various 'signatures' associated with heart complications. In the future, such instruments could be pivotal for making informed decisions in managing cardiovascular and other diseases, paving the way for more tailored treatment strategies. The Pathway to Predictive, Personalized Care The development of the CVD-21 instrument marks a significant step toward being able to quantify varied cardiovascular processes using just a drop of blood. Not only does this herald a more patient-friendly approach to testing, but it also opens the door to a more personalized and predictive care model when dealing with cardiovascular diseases. This breakthrough tool has been made possible through a collaboration between Uppsala University, Olink Proteomics and SciLifeLab, further underlining the importance of cross-disciplinary partnerships in advancing health care technologies and solutions.
