Abstract Background: Acute Heart Failure (AHF) is a common condition that often manifests by acute respiratory distress and requires urgent medical evaluation and treatment. Arterial hypercapnia is common in AHF. It has been associated with a higher rate of intubation and non-invasive ventilation in the Emergency Room (ER), but its prognostic value has never been studied in the prehospital setting. Methods: A retrospective study was performed on the charts of all patients taken care of by a physician-staffed prehospital mobile unit between June 2016 and September 2019 in Geneva. After approval by the ethics committee, charts were screened to identify all adult patients with a diagnosis of AHF. The main predictor was prehospital hypercapnia. The primary outcome was admission rate in an acute care unit (ACU, composite of intensive care or high-dependency units). Secondary outcomes were ER length of stay (LOS), orientation from ER (intensive care unit, high-dependency unit, general ward, discharge home), intubation rate at 24 hours, hospital LOS and hospital mortality. Results: A total of 104 patients with a diagnosis of AHF were included. Hypercapnia was found in 59 (57%) patients and vital signs were more severely altered in this group. The overall ACU admission rate was 47%, with a statistically significant difference between hypercapnic and non-hypercapnic patients (58% vs 33% respectively, p=0.014). ER LOS was shorter in hypercapnic patients (5.5 hours vs 8.9 hours, p=0.008). Conclusions: There is a significant association between prehospital arterial hypercapnia and acute care unit admission in AHF patients. Trial Registration:This study was approved on 20.08.2019 by the institutional ethics committee of Geneva, Switzerland (Project ID 2019-01559)

After approval by the ethics committee, charts were screened to identify all adult patients with a diagnosis of AHF in whom a prehospital arterial blood gas (ABG) sample was drawn. The main predictor was prehospital hypercapnia. The primary outcome was the admission rate in an acute care unit (ACU, composite of intensive care and high-dependency units). Secondary outcomes were ER length of stay (LOS), orientation from ER (intensive care unit, high-dependency unit, general ward, discharge home), intubation rate at 24 h, hospital LOS and hospital mortality. Results A total of 106 patients with a diagnosis of AHF were analysed. Hypercapnia was found in 61 (58%) patients and vital signs were more severely altered in this group. The overall ACU admission rate was 48%, with a statistically significant difference between hypercapnic and non-hypercapnic patients (59% vs 33%, p = 0.009). ER LOS was shorter in hypercapnic patients (5.4 h vs 8.9 h, p = 0.016). Conclusions There is a significant association between prehospital arterial hypercapnia, acute care unit admission, and ER LOS in AHF patients.

Abstract Background A structure and staffing model similar to that in general intensive care unit (ICUs) is applied to cardiac intensive care unit (CICUs) for patients with acute heart failure. However, there is limited evidence on the structure and staffing model of CICUs. The present study aimed to assess whether critical care for patients with acute heart failure in the ICUs is associated with improved outcomes than care in the high-dependency care units (HDUs), the hospital units in which patient care levels and costs are between the levels found in the ICU and general ward. Methods This nationwide, propensity score-matched, retrospective cohort study was performed using a national administrative inpatient database in Japan. We identified all patients who were hospitalized for acute heart failure and admitted to the ICU or HDU on the day of hospital admission from April 2014 to March 2019. Propensity score-matching analysis was performed to compare the in-hospital mortality between acute heart failure patients treated in the ICU and HDU on the day of hospital admission. Results Of 202,866 eligible patients, 78,646 (39%) and 124,220 (61%) were admitted to the ICU and HDU, respectively, on the day of admission. After propensity score matching, there was no statistically significant difference in in-hospital mortality between patients who were admitted to the ICU and HDU on the day of admission (10.7% vs. 11.4%; difference, − 0.6%; 95% confidence interval, − 1.5% to 0.2%). In the subgroup analyses, there was a statistically significant difference in in-hospital mortality between the ICU and HDU groups among patients receiving noninvasive ventilation (9.4% vs. 10.5%; difference, − 1.0%; 95% confidence interval, − 1.9% to − 0.1%) and patients receiving intubation (32.5% vs. 40.6%; difference, − 8.0%; 95% confidence interval, − 14.5% to − 1.5%). There were no statistically significant differences in other subgroup analyses. Conclusions Critical care in ICUs was not associated with lower in-hospital mortality than critical care in HDUs among patients with acute heart failure. However, critical care in ICUs was associated with lower in-hospital mortality than critical care in HDUs among patients receiving noninvasive ventilation and intubation.

Background: Acute heart failure (AHF) is a severe clinical syndrome characterized as rapid onset or worsening of symptoms of chronic heart failure (CHF). Risk stratification for patients with AHF in the intensive care unit (ICU) may help clinicians to predict the 28-day mortality risk in this subpopulation and further raise the quality of care.Methods: We retrospectively reviewed and analyzed the demographic characteristics and serological indicators of patients with AHF in the Medical Information Mart for Intensive Care III (MIMIC III) (version 1.4) between June 2001 and October 2012 and our medical center between January 2019 and April 2021. The chi-squared test and the Fisher's exact test were used for comparison of qualitative variables among the AHF death group and non-death group. The clinical variables were selected by using the least absolute shrinkage and selection operator (LASSO) regression. A clinical nomogram for predicting the 28-day mortality was constructed based on the multivariate Cox proportional hazard regression analysis and further validated by the internal and external cohorts.Results: Age > 65 years [hazard ratio (HR) = 2.47], the high Sequential Organ Failure Assessment (SOFA) score (≥3 and ≤8, HR = 2.21; ≥9 and ≤20, HR = 3.29), lactic acid (Lac) (>2 mmol/l, HR = 1.40), bicarbonate (HCO3-) (>28 mmol/l, HR = 1.59), blood urea nitrogen (BUN) (>21 mg/dl, HR = 1.75), albumin (<3.5 g/dl, HR = 2.02), troponin T (TnT) (>0.04 ng/ml, HR = 4.02), and creatine kinase-MB (CK-MB) (>5 ng/ml, HR = 1.64) were the independent risk factors for predicting 28-day mortality of intensive care patients with AHF (p < 0.05). The novel nomogram was developed and validated with a promising C-index of 0.814 (95% CI: 0.754–0.882), 0.820 (95% CI: 0.721–0.897), and 0.828 (95% CI: 0.743–0.917), respectively.Conclusion: This study provides a new insight in early predicting the risk of 28-day mortality in intensive care patients with AHF. The age, the SOFA score, and serum TnT level are the leading three predictors in evaluating the short-term outcome of intensive care patients with AHF. Based on the nomogram, clinicians could better stratify patients with AHF at high risk and make adequate treatment plans.

Abstract Introduction Continuous reliable evaluating of left ventricular (LV) contractile function in patients with advanced heart failure requiring intensive care remains challenging. Recently, continual monitoring of dP/dtmax from arterial line became available for hemodynamic monitoring. However, the relation between arterial dP/dtmax and LV dP/dtmax measurement is not fully understood. Purpose The aim of our study was to determine the relation of arterial dP/dtmax and LV dP/dtmax assessed by echocardiography in patients with acute heart failure. Methods Forty-eight patients with acute heart failure requiring intensive care and hemodynamic monitoring were recruited into the study (mean age 70.4 years, 65% were males). Hemodynamic variables including arterial dP/dtmax were continually monitored using arterial line pressure waveform analysis. LV dP/dtmax was assessed using continuous-wave Doppler analysis of mitral regurgitation flow. Results The values from continual arterial dP/dtmax monitoring significantly correlated with the LV dP/dtmax assessed by echocardiography (r=0.72, 95% confidence interval [CI] 0.54–0.83, P<0.0001). Linear regression revealed that (LV dP/dtmax) = 0.87×(arterial dP/dtmax) + 291, P<0.0001. Arterial dP/dtmax significantly correlated also with the stroke volume (r=0.55, P<0.0001), cardiac output (r=0.32, P=0.0289), mean arterial blood pressure (r=0.43, P=0.0155) and systolic blood pressure (r=0.79, P<0001). On the other hand arterial dP/dtmax did not correlate with the systemic vascular resistance (SVR), heart rate, dynamic arterial elastance, diastolic blood pressure or central venous pressure. Conclusion Our results revealed that arterial dP/dtmax values tightly and highly significantly correlate with LV dP/dtmax. Arterial dP/dtmax could be, therefore, used for continual monitoring of LV contractility. Acknowledgement/Funding Institutional grant MH CZ - DRO (Na Homolce Hospital- NNH, 00023884), IG150501
