Utility of Cardiac Biomarkers in the Setting of Kidney Disease

Cardiovascular disease is prevalent in patients with chronic kidney disease (CKD) and responsible for approximately half of all CKD-related deaths. Unfortunately, the presence of CKD can lead to a challenging interpretation of cardiac biomarkers essential in accurate diagnosis and prompt management of heart failure and acute coronary syndrome. There is growing interest in novel cardiac biomarkers that may improve diagnostic accuracy reflecting myocardial injury, inflammation, and remodeling. Interpretation of these biomarkers in CKD can be complicated, since elevated levels may not reflect myocardial injury or wall tension but rather decreased urinary clearance with retention of solutes and/or overall CKD-associated chronic inflammation. In this review, we discuss the latest data on major and emerging cardiac biomarkers including B-type natriuretic peptide, troponin, suppression of tumorigenicity 2, growth and differentiation factor-15, galectin-3, and matrix gla protein, and their diagnostic and prognostic utility in the CKD population.
