A new tool that makes it possible to adapt treatment for patients with cardiogenic shock has been developed

A joint research effort by the Hospital and the Instituto de Investigación Germans Trias i Pujol (IGTP) is characterising and studying a new cohort of cardiogenic shock patients to predict the risk of having this heart attack-derived complication which, while infrequent, sometimes presents a fatal outcome. It is the first molecular study for risk prediction described for this disease and is based on a proteomic meta-analysis that has made it possible to discover biomarkers and validate their use in decision-making. The new method, combined with existing techniques, will help to implement more precise treatments. Moreover, the know-how has been patented and work is under way to transfer it to the immunological techniques widely used in clinical diagnosis, such as ELISA.

The objective of the study was to obtain a reliable method to predict which post-heart attack cardiogenic shock patients have a greater risk of not surviving. Cardiogenic shock is a possible complication of severe infarction in which the heart is suddenly unable to maintain the required blood flow. It does not occur in all heart attack cases, although it is fatal if it goes undetected and is not treated promptly. In this case, the discovery of four proteins that can be used as biomarkers is a new tool which, in conjunction with existing ones, makes it possible to pre-empt this complication more precisely.

The group led by Dr. Antoni Bayés-Genís at the Hospital e Instituto de Investigación Germans Trias i Pujol (CIBER Cardiovascular investigators) and Dr. Eduard Sabidó of the Proteomics Unit of the Centre for Genomic Regulation (CRG) and the Pompeu Fabra University (UPF)has identified 4 proteins (from more than 2600 analysed) that identify patients with cardiogenic shock and a poor vital prognosis. The work has been published in the European Heart Journal, the leading publication in the cardiovascular field.
