Abstract
Post-sepsis syndrome is a major concern affecting sepsis survivors. COVID-19 increases the risk of long-term complications, but existing data lack detail on patient-specific factors and long-term cardiovascular complications, namely major adverse cardiovascular events (MACE). Our objective was to analyze and compare the MACE occurrence, among COVID-19 survivors, according to the severity of infection. Adults aged ≥ 18 years infected during the first waves of COVID-19 pandemic hospitalized in Strasbourg University Hospital were included. Follow-up began immediately after COVID-19 diagnosis and continued for up to 12 months. Inverse probability of treatment weighting was used to balance baseline patient characteristics between the two groups (i.e. intensive care unit patients and medical ward patients). A total of 332 patients, i.e.132 in intensive care unit (ICU) and 200 in medical ward were included in the final analysis. The ICU population experienced a significantly higher risk of MACE during the first year (HR 16.2 [5.7–45.8] p < 0.001). Smoking status, history of peripheral arterial obstructive disease, and hospitalization in ICU remained independently associated with the occurrence of MACE in multivariable analysis. Severity of COVID-19 appears as an independent risk factor for MACE at one year among intensive care unit patients compared to those hospitalized in medical ward.
