Abstract

Background: Predicting and reducing the 28-day mortality in sepsis remains a challenge in this research field.

Objective: This study aimed to explore the association between hypertension and 28-day mortality in sepsis.

Methods: This study is a cross-sectional approach with Mendelian Randomization (MR). We used GWAS data for hypertension as the exposure and 28-day mortality in sepsis as the outcome and employed the main inverse variance weighted method along with other supplementary MR techniques to verify the causal association between hypertension and 28-day mortality in sepsis. We used sensitivity analyses to ensure the robustness of the research findings. Finally, we utilized clinical data from the Medical Information Mart for Intensive Care-IV database to assess the risk association between hypertension and 28-day mortality in sepsis using difference analysis and multivariate logistic regression analysis.

Results: According to MR, hypertension increased the 28-day mortality in sepsis in both two datasets (FinnGen: odds ratio [OR] = 1.61, 95 % confidence interval [CI] = 1.15-2.26, p = 0.006; Medical Research Council-Integrative Epidemiological Unit: OR = 160, 95 % CI = 2.76-9250, p = 0.014). In our observational study, we included a total of 2012 sepsis patients, of which 60.5 % were male, and the average age was 55.4 years. By applying univariate and multivariate logistic regression models (univariate analysis p = 0.02, multivariate analysis p = 0.02), we observed a significantly increased risk of 28-day mortality due to hypertension in sepsis patients.

Conclusion: This study confirmed the causal relationship between hypertension and the 28-day mortality in sepsis.

期刊介绍： Heart & Lung: The Journal of Cardiopulmonary and Acute Care, the official publication of The American Association of Heart Failure Nurses, presents original, peer-reviewed articles on techniques, advances, investigations, and observations related to the care of patients with acute and critical illness and patients with chronic cardiac or pulmonary disorders. The Journal''s acute care articles focus on the care of hospitalized patients, including those in the critical and acute care settings. Because most patients who are hospitalized in acute and critical care settings have chronic conditions, we are also interested in the chronically critically ill, the care of patients with chronic cardiopulmonary disorders, their rehabilitation, and disease prevention. The Journal''s heart failure articles focus on all aspects of the care of patients with this condition. Manuscripts that are relevant to populations across the human lifespan are welcome.
