Overview

Brief Summary

Prospective biomedical research study

Detailed Description

The aim is to validate a new biomarker, based on the levels of DNAmit present in blood, to assess the predisposition of an individual to suffer an infection. To validate this hypothesis, the DNAmit levels of patients with myocardial infarction will be analysed and their relationship with the probability of these patients developing an infectious process or not.

Eligibility Criteria

Inclusion Criteria

•Patients who have suffered AMI or cardiorespiratory arrest after AMI, have been admitted to hospital within the first 24 hours of the event and are required to be admitted to any Critical Care Unit. In addition, one of the following criteria must be met:
•Symptoms of cardiac ischaemia.
•New ischaemic patterns in the ECG.
•Development of pathological QW waves on the ECG.
•Obvious suspicion or loss of myocardial viability or new abnormal motility regions in a pattern consistent with ischaemic pathology.
•Intracoronary thrombus detected on angiography or autopsy.
•They must be of legal age, have read the Patient Information Sheet (HIP) and have signed the Informed Consent (IC).
•Depending on the group in which they are to be classified, patients must meet specific inclusion criteria:
•Group A: Patients who have suffered MI (myocardial infarction), are in the CRITICAL UNIT and their DNAmit values are below 0.25-105 copies.
•Group B: Patients who have suffered an MI, are in the CRITICAL UNIT and their mtDNA values are above 0.25-105 copies.

Exclusion Criteria

•Patients who meet any of the following criteria shall not be eligible for inclusion in the clinical trial:
•Chronic inflammatory diseases
•Transplantation of any organ (except cornea).
•Patients receiving or who have received in the last 3 months anti-inflammatory, immunosuppressive or biological treatment targeting the immune system (TNF blockers, anakinra, rituximab, abatacept or tocilizumab), except NSAIDs and colchicine.
•Patients with overt and/or severe immunocompromise
•History of chronic kidney or liver disease (dialysis or creatinine clearance \< 30%).
•Decompensated diabetes
•Active tumour process. Patients considered to be in complete remission may be included in the study.
•Major surgical intervention (in the 3 MONTHS PRIOR to inclusion in the study).
•Pregnancy, childbirth or breastfeeding in the last 3 months.
