Influence of ambulatory blood pressure-related indicators within 24 h on in-hospital death in sepsis patients

Abstract

Background: Sepsis is a serious public health problem worldwide. Blood pressure is one of the indicators that is closely monitored in intensive-care units, and it reflects complex interactions between the internal cardiovascular control mechanism and the external environment. We aimed to determine the impact of indicators related to the ambulatory blood pressure on the prognosis of sepsis patients. Methods: This retrospective study was based on the Medical Information Mart for Intensive Care IV database. Relevant information about sepsis patients was extracted according to specific inclusion and exclusion criteria. Examined parameters included the average blood pressure, blood pressure variability (BPV), and circadian rhythm, and the study outcome was in-hospital death. We investigated the effects of these indicators on the risk of in-hospital death among sepsis patients using Cox proportional-hazards models, restricted cubic splines analysis, and subgroup analysis. Results: This study enrolled 10,316 sepsis patients, among whom 2,117 died during hospitalization. All parameters except the nighttime variation coefficient of the diastolic blood pressure (DBP) were associated with in-hospital death of sepsis patients. All parameters except for fluctuations in DBP exhibited nonlinear correlations with the outcome. The subgroup analysis revealed that some of the examined parameters were associated with in-hospital death only in certain subgroups. Conclusion: Indicators related to the ambulatory blood pressure within 24 h are related to the prognosis of sepsis patients. When treating sepsis, in addition to blood pressure, attention should also be paid to BPV and the circadian rhythm in order to improve the prognosis and the survival rate.

Perfil clínico e preditores de mortalidade intra-hospitalar em adultos criticamente doentes com sepse: revisão integrativa

“…Ademais, taquicardia, leucocitose e rebaixamento da consciência foram causadores de agravamento do quadro clínico (D'Onofrio et al, 2020). Outra pesquisa mostrou maior taxa de mortalidade na utilização de ventilação mecânica (84,2%) e uso de vasopressores, equivalentes de norepinefrina (67,5%) em 2.117 pacientes (Xu et al, 2022). Portanto, além da avaliação da pressão arterial, deve-se atentar para os indicadores de ritmo circadiano, infusões de medicamentos com titulação vasopressor e uso do ventilador mecânico para melhorar o prognóstico e tratamento dos pacientes.…”

U-shaped Association between Serum Calcium Levels and 28-Day Mortality in Patients with Sepsis: A Retrospective Analysis of the MIMIC-III Database

“…Multiple risk factors, such as advanced age ( 38 ), hyperlactatemia ( 39 ), cancer ( 40 ), hypotension ( 41 ), hypothermia ( 42 ), thrombocytopenia ( 43 ), hypocoagulability ( 44 ), and high procalcitonin ( 45 ), were associated with poor outcomes in patients with sepsis. Consistent with the previous study, univariate analysis in this study also revealed that advanced age, decreased SBP, DBP and MAP, low body temperature, presence of metastatic cancer, high lactate levels, low platelet count, and elevated APTT, PT, and INR were positively associated with 28-day mortality in sepsis.…”
