Cardiotoxicity of Carbon Monoxide in Patients Treated With Hyperbaric Oxygen Therapy

Cardiotoxicity of Carbon Monoxide in Patients Treated With Hyperbaric Oxygen Therapy

Carbon monoxide poisoning is a frequent domestic accident and the leading cause of death from unintentionnal poisoning. Its toxicity is based on the CO binding to hemoglobin and myoglobin, inhibition of mitochondrial cytochrome oxidase, resulting in tissue hypoxia and reduced adenosine triphosphate synthesis and ischemia-reperfusion injury.

This study aims to investigate the early and late cardiologic effects of CO in patients treated with hyperbaric oxygen (HBOT) for CO poisoning

This is a single-center retrospective study on health data. The methodology includes a collection of data on health and history data of patients treated by HBOT fo CO poisoning between 01/01/2015 and 31/12/2021 and carrying out a telephone interview of patients who have had early cardiovascular manifestations of CO poisoning.

One month between the start of theses interviews, an information letter on the study is sent by post, giving the possibility of opposing it.

Inclusion Criteria:

Patients treated for CO poisoning with HBOT in the hyperbaric and underwater medicine department of the Brest University hospital from 2015/01/01 to 2021/12/31

Exclusion Criteria:

• refusal
