MACCE in Hospitalized Patients With Community-acquired Pneumonia
Community-acquired pneumonia is the most common infection leading to hospitalization in intensive care units and the most common cause of death associated with infection disease.
Epidemiological studies have shown that respiratory tract infections are associated with an increased risk for the development of acute cardiovascular and cerebrovascular events.
This link is further supported by studies indicating that influenza vaccination is associated with a reduced risk of hospitalization for pneumonia as well as heart disease and cerebrovascular disease.
Data connecting acute respiratory tract infections and cardiovascular events stem almost exclusively from cross-sectional or retrospective studies. Thus the real incidence and the prognostic impact of AMI, as well as the pathophysiological relationship between pneumonia and cardiovascular damage is still elusive.
Inflammation plays a major role in the pathogenesis of coronary artery disease. The increased concentrations of proinflammatory cytokines together with the activation of coagulation, the down-regulation of anticoagulant mechanisms and the enhanced platelet aggregation may trigger atheroma's instability, plaque rupture and thrombus formation.
Inflammation and coagulopathy are also considered universal host responses to infection in patients with severe sepsis. Thus far limited data are available on the changes in these high regulated systems, together with platelet activity in patients with CAP and their potential relationship with cardiovascular risk.
This project will consist in a prospective multicenter study to investigate the incidence of major adverse cardiac and cerebrovascular events (MACCE) in hospitalized patients with CAP, its prognostic relevance and the potential relationship between enhanced cardiovascular risk and the activation of inflammation, coagulation and platelet aggregation in this setting.
