Summary

Acute pneumonia is a very common disease, and one of the leading causes of hospitalization and death in France. Almost a century after the discovery of penicillin, no major breakthrough has significantly reduced pneumonia-related mortality. While the choice of an appropriate antibiotic is decisive in the acute phase of the disease, the longer-term prognosis depends essentially on the worsening of other underlying pathologies, particularly in the elderly. In cured patients, excess mortality persists several months after the episode of pneumonia, due in particular to the onset of cardiovascular complications. Recent scientific literature shows an association between the prescription of cardio-protective drugs and survival after pneumonia. Older patients are usually excluded from interventional studies, so there are no specific recommendations for these patients at high risk of both acute pneumonia and cardiovascular events. The aim of this study is to assess the efficacy of low-dose aspirin therapy after pneumonia in preventing cardiovascular events in the elderly. The main objective is therefore to evaluate the impact of aspirin at a dose of 100mg per day on all-cause mortality at 90 days in patients over 75 years of age hospitalized for pneumonia.

Interventions

DRUG

Acetylsalicylic acid/Aspirin (100 mg)

Patients will receive 100 mg acetylsalicylic acid (or Aspirin) orally (tablet) once a day (or intravenously if oral administration is not possible in the acute phase of pneumonia), introduced within 84 hours of pneumonia diagnosis, for 90 days.

DRUG

Placebo acetylsalicylic acid (100 mg) / 0.9% sodium chloride

patients in the placebo group will receive 100 mg placebo acetylsalicylic acid orally (tablet) once a day (or intravenously if oral administration is not possible in the acute phase of pneumonia), introduced within 84 hours of pneumonia diagnosis, for 90 days.
