Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The HOMI-LUNG - HAP study is part of the HOMI-LUNG project, funded by the Horizon Europe program. The "HOMI-LUNG" project is an international, interdisciplinary project that aims to better understand the causal links between respiratory tract infections (i.e. pneumonia) and the progression of cardiovascular disease. More specifically, the project aims to quantify the burden of cardiovascular disease after pneumonia and assess patients\' acceptability of long-term health alterations, as well as to define pneumonia endotypes with distinct pathobiological mechanisms associated with exacerbation of cardiovascular disease.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A : Patients with acute major cardiovascular event

Comparator

Group Type OTHER

Blood samples

Intervention Type OTHER

Four blood samples will be taken outside standard care for groups A, B, C and D: at inclusion, M6, M18 and M30 (only at inclusion for group C).

Oropharyngeal swabs

Intervention Type OTHER

An oropharyngeal swab will be taken to analyze patients\' upper airway microbiome at inclusion, M6, M18 and M30.

Calcium score (CT scan)

Intervention Type OTHER

A calcium score will be taken at 30 months, to assess individual cardiovascular risk.

ECG

Intervention Type OTHER

Performed at inclusion, M6, M18 and M30

Cardiopulmonary exercise test, spirometry, plethysmography, pulmonary absorption of carbon monoxide in a single inspiration, and 6-minute walk test

Intervention Type OTHER

Cardiopulmonary exercise test, spirometry, plethysmography, pulmonary absorption of carbon monoxide in a single inspiration, and 6-minute walk test: These tests will be performed consecutively for 2 hours at inclusion (6-minute walk test only), at M6 and at M30. These tests will be performed to assess respiratory and cardiac function.

Group B: Patients with severe chronic cardiovascular disease

Comparator

Group Type OTHER

Blood samples
