OBJECTIVE: This study aims to identify risk factors associated with septic cardiomyopathy (SCM) in patients diagnosed with septic shock and to assess differences in clinical outcomes between those with septic shock alone and those with concomitant SCM.
METHODS: A retrospective observational study was conducted on 108 patients diagnosed with septic shock and admitted to Beijing Tongren Hospital, Capital Medical University, between December 2022 and July 2024. Patients were stratified into two groups based on the presence or absence of SCM: the non-SCM group (n = 90) and the SCM group (n = 18). Baseline characteristics, laboratory markers, cardiac function indices, and clinical outcomes were compared between the two groups. Multivariate logistic regression was employed to identify risk factors for SCM. Within the SCM group, outcomes were further analyzed according to survival status to assess the association between cardiac function recovery and mortality.
RESULTS: The incidence of SCM among patients with septic shock was 16.67%. Compared with the non-SCM group, the SCM group showed a significantly higher prevalence of urinary tract infections and a history of diabetes mellitus ( P < 0.05). Higher scores were observed for the Acute Physiology and Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment scales, along with increased levels of admission-day troponin I, interleukin-1 (IL-1), tumor necrosis factor-α, maximum lactic acid (LACmax), maximum brain natriuretic peptide, and peak troponin I ( P < 0.05). In contrast, mean arterial pressure at admission, minimum left ventricular ejection fraction (LVEF), and end-point LVEF (LVEFend%) were significantly lower in this group ( P < 0.05). Multivariate logistic regression identified elevated IL-1 levels (odds ratio [OR] = 1.14), higher APACHE II scores (OR = 1.13), and increased LACmax (OR = 1.47) as risk factors for SCM ( P < 0.05). The presence of SCM was associated with significantly higher in-hospital mortality and increased healthcare costs ( P < 0.05). Among patients with SCM, recovery of LVEF and cardiac output was correlated with improved survival outcomes.
CONCLUSIONS: Elevated IL-1 levels, increased peak lactic acid concentration, and higher APACHE II scores were associated with the development of SCM in patients with septic shock. SCM was further associated with increased mortality and greater healthcare resource utilization. Restoration of cardiac function, particularly improvements in LVEF and cardiac output, was correlated with improved prognosis and may serve as a valuable indicator of clinical outcomes.
