Risk factors and prognostic implication of acute pulmonary edema in resuscitated out-of-hospital cardiac arrest patients

Background and Purpose: In-hospital cardiac arrest (IHCA) has high mortality rate, which needs more research. This multi-center study aims to evaluate potential risk factors for mortality in patients after IHCA.Methods: Data for this study retrospectively enrolled IHCA patients from 14 regional hospitals, two district hospitals, and five medical centers between 2013 June and 2018 December. The study enrolled 5,306 patients and there were 2,871 patients in subgroup of intensive care unit (ICU) and emergency room (ER), and 1,894 patients in subgroup of general wards.Results: As for overall IHCA patients, odds ratio (OR) for mortality was higher in older patients (OR = 1.69; 95% CI:1.33–2.14), those treated with ventilator (OR = 1.79; 95% CI:1.36–2.38) and vasoactive agents (OR = 1.88; 95% CI:1.45–2.46). Whereas, better survival was reported in IHCA patients with initial rhythm as ventricular tachycardia (OR = 0.32; 95% CI: 0.21–0.50) and ventricular fibrillation (OR = 0.26; 95% CI: 0.16–0.42). With regard to ICU and ER subgroup, there was no mortality difference among different nursing shifts, whereas for patients in general wards, overnight shift (OR = 1.83; 95% CI: 1.07–3.11) leads to poor outcome.Conclusion: For IHCA patients, old age, receiving ventilator support and vasoactive agents reported poor survival. Overnight shift had poor survival for IHCA patients in general wards, despite no significance in overall and ICU/ER subgroups.

Abstract Background: Early identification of risk factors for short-term mortality in patients with in-hospital cardiac arrest (IHCA) is crucial for early prognostication. This study aimed to explore the association of early dynamic changes in inflammatory markers with 30-day mortality in IHCA patients.Methods: This study retrospectively collected demographic and clinical characteristics and relevant laboratory indicators within 72 h after recovery of spontaneous circulation (ROSC) of IHCA patients from December 2015 to December 2020 at the First Affiliated Hospital of Chongqing Medical University. The outcome was 30-day mortality. A linear mixed model was used to analyze the dynamic changes in laboratory indicators within 72 h after ROSC, and Cox regression was used to identify the independent risk factors for 30-day mortality.Results: Overall, 85 IHCA patients were included. The 0-72h and 0-30day cumulative mortality rates were 25.88% and 57.65%, respectively, and the median survival time was 13.79 days. There was no association of inflammatory markers before IHCA with mortality. Within 72 h after ROSC, inflammatory markers showed various changes: the absolute monocyte count (AMC) showed no significant change trend, and the absolute lymphocyte count (ALC) showed an overall upward trend, while the absolute neutral count (ANC), white blood cell (WBC) count, platelet (PLT) count, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and systemic immune-inflammation index (SII) showed an overall downward trend. Cox multivariate analysis showed that Charlson comorbidity index (CCI) (HR = 2.366, 95%CI (1.084, 5.168)), APACHE II score (HR = 2.550, 95% CI (1.001, 6.498)), abnormal Cr before IHCA (HR = 3.417, 95% CI (1.441, 8.104)) and PLR within 72 h after ROSC (HR = 2.993, 95% CI (1.442, 6.214)) were independent risk factors for 30-day mortality. When PLR ≥ 180, the risk of 30-day mortality increased by 199.3%.Conclusions: This study clarified the dynamic change trends of inflammatory markers within 72 h after ROSC. The PLR was an independent risk factor for 30-day mortality in IHCA patients; it can be used as a predictor of short-term mortality and provide a reference for early prognostication.Trial registration: ChiCTR1800014324

Hospital Cardiac Arrest

ObjectivePatients with bipolar disorder and schizophrenia are at high cardiovascular risk; yet, the risk of out-of-hospital cardiac arrest (OHCA) compared with the general population remains scarcely investigated.MethodsWe conducted a nested case-control study using Cox regression to assess the association of bipolar disorder and schizophrenia with the HRs of OHCA of presumed cardiac cause (2001–2015). Reported are the HRs with 95% CIs overall and in subgroups defined by established cardiac disease, cardiovascular risk factors and psychotropic drugs.ResultsWe included 35 017 OHCA cases and 175 085 age-matched and sex-matched controls (median age 72 years and 66.9% male). Patients with bipolar disorder or schizophrenia had overall higher rates of OHCA compared with the general population: HR 2.74 (95% CI 2.41 to 3.13) and 4.49 (95% CI 4.00 to 5.10), respectively. The association persisted in patients with both cardiac disease and cardiovascular risk factors at baseline (bipolar disorder HR 2.14 (95% CI 1.72 to 2.66), schizophrenia 2.84 (95% CI 2.20 to 3.67)) and among patients without known risk factors (bipolar disorder HR 2.14 (95% CI 1.09 to 4.21), schizophrenia HR 5.16 (95% CI 3.17 to 8.39)). The results were confirmed in subanalyses only including OHCAs presenting with shockable rhythm or receiving an autopsy. Antipsychotics—but not antidepressants, lithium or antiepileptics (the last two only tested in bipolar disorder)—increased OHCA hazard compared with no use in both disorders.ConclusionsPatients with bipolar disorder or schizophrenia have a higher rate of OHCA compared with the general population. Cardiac disease, cardiovascular risk factors and antipsychotics represent important underlying mechanisms.
