Cardiac biomarkers

A cardiac biomarker is a molecule of varying nature (proteins, metabolites, microRNAs ...) that is released into the blood when heart damage occurs. Reference patterns as biomarkers in heart failure are the type B natriuretic peptide and the aminoterminal fraction of the type B natriuretic propeptide, which play an important role in the diagnosis, prognosis and treatment of decompensated acute cardiac insufficiency. However, more and more biomarkers are discovered and associated with other processes of myocardial injury, neurohormonal activation and remodeling of the ventricular heart.

Heart failure is a very heterogeneous disease without an individualized therapeutic approach. Currently, in other types of diseases such as cancer, more personalized treatments are being sought depending on the individualized characteristics of each patient. In this same way, we think that a more personalized approach is needed for the management of heart failure. As a result of this situation, the Pure Heart Precision Medicine Platform is born within the ICREC group, for optimizing the value of certain biomarkers that improve the diagnosis, prognosis and the management of the patients with heart failure.

In this regard, we have recently published several papers that demonstrate the association of certain biomarkers with the ability to predict the evolution of the patient's disease and stratification risk. For example, in patients with severe asymptomatic aortic stenosis, a concentration of high sensitivity troponin T greater than 10ng/L is associated with a high risk of events within 12 months and the inclusion of this biomarker in the management of This pathology makes it possible to significantly improve risk prediction metrics. We have also seen that in patients with myocardial infarction with elevation of the ST segment, the assessment of the circulating levels of GDF-15 in the first 24 hours is very valuable to predict especially short-term results. We have recently developed an ST2-R2 score that allows the clinical practice to predict the reverse remodeling of the left ventricle in patients with systolic heart failure. In turn, we have patented neprilisin as a prognostic biomarker of heart failure.

We are currently deepening in the study of known biomarkers and discovering new biomarkers that help us improving the management of cardiac pathology. For this, we have extensive collections of plasma and serum samples of treated patients in the Cardiology Service and we collaborate with other hospitals, both national and international.
