Brief Summary

Pneumonia can be acquired in the community (CAP) or during hospitalization (HAP). It is a leading cause of communicable diseases and the second cause of disability-adjusted life-years in the world (Roquilly et al., Shankar-Hari et al.). HAP is a common infectious disease, affecting up to 40% of patients on mechanical ventilation. It is a major global concern, with 500,000 cases treated annually in Europe. Despite European guidelines, the incidence remains high (Roquilly et al.), leading to significant medical consequences. Thanks to improved early detection and appropriate medical management, pneumonia-related mortality has steadily declined over the past decades. As a result, the number of patients surviving with potential long-term sequelae has increased, with risks of pulmonary function abnormalities, psychological disorders, and impaired quality of life (Shankar-Hari et al., Sipilä et al., Corrales-Medina et al., Ahmed et al.). Cardiovascular and respiratory diseases (CVRD) are the most common pre-existing conditions in patients with pneumonia, with up to 40% of patients presenting these comorbidities at the time of pneumonia diagnosis (Roquilly et al., Nojiri et al.). The risk of severe cardiovascular and respiratory events increases after pneumonia recovery, with 14% of patients developing a CVRD event within the first year post-infection (Corrales-Medina et al., Herridge et al.), representing a 40% relative increase in CVRD risk compared to patients with CVRD without infection (Lai et al., Angriman et al.). The objective of the ARCADIA study is to describe the incidence of cardiovascular diseases (CVD) in individuals surviving pneumonia and to compare it to that of patients with similar predisposing comorbidities for CVD but without a history of pneumonia. The investigators hypothesize that pneumonia is a cause of CVD so that patients with a history of pneumonia have a higher risk of developing CVD.

Outcome Measures

Primary Outcomes (1)

  • 4-points MACE and 5-points MACE

    Acute events relating to the following pathologies are the main outcomes of the ARCADIA study: * Acute Coronary Syndrome (MeSH Unique ID: D054058) * Lower limb revascularization or major amputation * Ischemic Stroke (D000083242) * Heart Failure (D006333) requiring Hospitalization (D006760) The primary outcome is therefore a composite outcome, called "4-points MACE", defined by the occurrence of at least one acute event related to the previously cited pathologies. The incidence of 4-point MACE will be compared between groups using an incidence density ratio (IDR) and its 95% confidence interval. This primary analysis will be replicated by adding all-cause mortality (MeSH Unique ID: D003643) to the 4-point MACE described above, defining a 5-points MACE.

    Up to 10 years

Secondary Outcomes (1)

  • 4-points chronic CVD

    Up to 10 years

Study Arms (2)

Exposed group

Exposure is defined as having reported any kind of pneumonia during the inclusion period. Once a participant has developed pneumonia, he or she belongs to the exposed group throughout the follow-up period.

Unexposed group

The unexposed group is made up of participants who have not developed pneumonia prior to inclusion and who have been matched to a participant in the exposed group on selected confounders.

Sampling MethodProbability Sample
Study Population

The French National Health Data System (SNDS) is a database that centralizes health-related data covering over 99% of residents (Tuppin et al.). Its primary objective is to support epidemiological research and health care system evaluation. It enables longitudinal analyses of health care pathways by linking data sources through anonymized identifiers. SNDS include information on reimbursed outpatient care and deliveries, hospital discharge summaries and medical procedures, death and related causes and list of pathologies requiring chronic care. These datasets collectively enable large-scale population-based studies on health care utilization, costs, morbidity and mortality. SNDS enable epidemiological studies to be conducted with more than 10 years of hindsight on nearly 68 million people.

You may qualify if:

  • Be at least 18 years of age in the month of the index date.
  • Exposed group: participants who declared pneumonia between January 1, 2015 and November 30, 2024.
  • Unexposed group: participants who did not declare pneumonia between January 1, 2015 and index date and being selected after matching on age, sex, CVD history, chronic kidney disease, diabetes, antihypertensive deliveries, obesity, lipid-lowering treatments, alcohol and tobacco consumption.

You may not qualify if:

  • Declared pneumonia between January 1, 2012 and December 31, 2014.
  • Pneumonia before the age of 18 between January 1, 2015, and the index date.
  • Organ transplant receiver for any of the following organs before or within one year after the index date: heart, kidney, lung, liver, and pancreas.
  • Identifier that cannot be reliably tracked in the SNDS (such as a fictitious or provisional identifier, or an identifier that, under specific regimen, fails to distinguish same-sex twins in hospital records).
  • Death during index hospitalization.
