Official Title: Myocardial Injury in Severe Pneumococcal Pneumonia as a Cause of Mortality From Acute Cardiovascular Events

Brief Summary:

Hypothesis: The "novo" cardiovascular events (CVE)in patients with severe community-acquired pneumonia (CAP) are frequent (17%) and could be associated with both direct pneumococcal myocardial invasion, toxin delivery (pneumolysin) or different biomarkers (histones, NETs(neutrophil extracellular traps), IL (Interleukin)-1b,h-Fabp (heart-Fatty acid bindding protein) ).The CVE frequency and its impact on outcome in patients without prior heart disease (CP) has not been studied.

Objectives:1) To determine the incidence of myocardian injury (MI) and CVE in patients with CAP without CP evaluated by non-invasive techniques (Echocardiograph and MRI) and biomarkers levels (Tn-I (Troponin I), h-Fabp, NT-proBNP (N-terminal pro-brain natriuretic peptide) histones, NETs, IL 1b); 2) To assess if DMA and CVE are related to the etiology and their impact on outcome , 3) To investigate the presence of myocardial scarring by MRI and its relationship with etiology and MI, and 4) To identify prognostic factors of DMA and CVE to determine level of risk.
