Cardiogenic shock (CS) is characterized by low cardiac output and sustained tissue hypoperfusion that may result in end-organ dysfunction and death. CS is associated with high short-term mortality, and its management remains challenging despite recent advances in therapeutic options. Timely diagnosis and multidisciplinary team-based management have demonstrated favourable effects on outcomes. We aimed to review evidence-based practices for managing patients with ischemic and non-ischemic CS, detailing the multi-organ supports needed in this critically ill patient population.

Simple Summary: The involvement of the renin-angiotensin pathway in both the regulation of the cardiovascular system and in tumorigenesis raises the question of the prognostic impact of renin-angiotensin system blockers (RABs) in cancer patients experiencing life-threatening complications. The aim of our retrospective study was to assess this impact in solid tumor patients requiring unplanned ICU admission over a 14-year period. Among 1845 patients mainly diagnosed with gastrointestinal and lung cancers, 414 (22.4%) were treated with RABs: 220 (53.1%) with angiotensin-receptor blockers (ARBs) and 194 (46.9%) with angiotensin-converting enzyme inhibitors (ACEis). ARBs use and ACEis use were both associated with improved in-ICU survival, whereas only ARBs use was associated with improved one-year survival. Increasing evidence argues for the promotion of tumorigenesis through activation of the renin-angiotensin system pathway. Accordingly, a benefit of renin-angiotensin system blockers (RABs) treatments has been suggested in patients with solid cancers in terms of survival. We aimed to evaluate in-ICU survival and one-year survival in cancer patients admitted to the ICU with respect to the use of RABs. We conducted a retrospective observational single-center study in a 24-bed medical ICU. We included all solid cancer patients (age ≥ 18 years) requiring unplanned ICU admission. From 2007 to 2020, 1845 patients with solid malignancies were admitted (median age 67 years (59–75), males 61.7%). The most frequent primary tumor sites were the gastrointestinal tract (26.8%), the lung (24.7%), the urological tract (20.1%), and gynecologic and breast cancers (13.9%). RABs were used in 414 patients, distributed into 220 (53.1%) with angiotensin-receptor blockers (ARBs) and 194 (46.9%) with angiotensin-converting enzyme inhibitors (ACEis). After multivariate adjustment, ARBs use (OR = 0.62, 95%CI (0.40–0.92), p = 0.03) and ACEis use (OR = 0.52, 95%CI (0.32–0.82), p = 0.006) were both associated with improved in-ICU survival. Treatment with ARBs was independently associated with decreased one-year mortality (OR = 0.6, 95%CI (0.4–0.9), p = 0.02), whereas treatment with ACEis was not. In conclusion, this study argues for a beneficial impact of RABs use on the prognosis of critically ill cancer patients. [ABSTRACT FROM AUTHOR]

We hypothesized that a prolonged follow-up of survivors of unexplained sudden cardiac arrest (USCA) would subsequently unmask electrical heart disorders in a significant proportion of cases. We retrospectively analyzed all out-of-hospital cardiac arrest (OHCA) admitted alive in our cardiac arrest center over 20-years (2002–2022). The diagnosis of USCA was made when no etiology was found after thorough initial hospital investigations. We identified all the new diagnoses established during follow-up, and compared outcomes according to underlying heart diseases. Out of the 2482 OHCA patients, 68 (2.7%) were initially classified as USCA and 30 (1.2%) with electrical heart disorders. Compared to other cardiac etiologies of OHCA, both USCA and electrical heart disorders patients were younger (mean age 48.5 and 43.5 year-old respectively, versus 62.5 year-old; p < 0.0001), with a higher rate of family history of SCA (17.6 and 23.3% respectively versus 9.2%; p = 0.003). Six patients in each group were lost to follow-up at discharge (6/68, 8.8% in the USCA group, 6/30 20% in the electrical heart disorders group). During a mean follow-up of 8.1 ± 6.3 years, a diagnosis was eventually established in 24.3% of USCA patients (9/35), most of them as electrical heart disorders (55.6%, 5/9). No post-discharge death occurred in both USCA and electrical heart disorders groups, with approximately 10% of appropriate therapy delivered by the implantable cardioverter defibrillator. Our findings emphasized that approximately a quarter of patients who had been initially considered as having apparently USCA after index hospital stay actually reveal heart conditions, especially electrical heart disorders.

Aim: Out-of-hospital Cardiac Arrest (OHCA) carries a poor prognostic with high mortality rates and multiple scoring systems have been developed to assess its prognostic. This study sought to evaluate the performance of three prognostic scores to predict survival in OHCA patients due to acute coronary syndrome (ACS).Methods and Results: This is an observational, monocentric study including 386 consecutive patients treated for OHCA due to ACS, treated by percutaneous coronary intervention, between 2007 and 2019. The OHCA, NULL-PLEASE and CAHP scores were calculated respectively for 370 patients (95.9%), 371 patients (96.1%) and 350 patients (90.7%). A C-statistic analysis was performed to determine score performance. The areas under the curve for the OHCA, NULL-PLEASE and CAHP scores were 0.861 (95% CI, 0.823-0.898), 0.789 (95% CI, 0.744-0.834) and 0.830 (95% CI, 0.788-0.872) respectively demonstrating good performance. The OHCA score performed better than the NULL-PLEASE score (p = 0.001), and there was no difference between the CAHP and the NULL-PLEASE score (p = 0.062) nor between the OHCA and the CAHP score (p = 0.105).Conclusion: The OHCA score, the NULL-PLEASE score and the CAHP score performed well in predicting in-hospital death in patients presenting OHCA secondary to ACS. The NULL-PLEASE score is the easiest to use but performed less accurately than the OHCA score. [ABSTRACT FROM AUTHOR]

Introduction: The management of pain and anxiety remains a challenge in the intensive care unit. By distracting patients, virtual reality (VR) may have a role in painful procedures. We compared VR vs. an inhaled equimolar mixture of N2O and O2 (Kalinox®) for pain and anxiety management during the removal of chest drains after cardiac surgery. Methods: Prospective, non-inferiority, open-label study. Patients were randomized, for Kalinox® or VR session during drain removal. The analgesia/nociception index (ANI) was monitored during the procedure for objective assessment of pain and anxiety. The primary endpoint was the ΔANI (ANImin − ANI0) during the procedure, based on ANIm (average on 4 min). We prespecified VR as non-inferior to Kalinox® with a margin of 3 points. Self-reported pain and anxiety were also analysed using numeric rate scale (NRS). Results: 200 patients were included, 99 in the VR group and 101 in the Kalinox® group; 90 patients were analysed in both groups in per-protocol analysis. The median age was 68.0 years [60.0–74.8]. The ΔANI was − 15.1 ± 12.9 in the Kalinox® group and − 15.7 ± 11.6 in the VR group (NS). The mean difference was, therefore, − 0.6 [− 3.6 to 2.4], including the non-inferiority margin of 3. Patients in the VR group had a significantly higher pain NRS scale immediately after the drain removal, 5.0 [3.0–7.0] vs. 3.0 [2.0–6.0], p = 0.009, but no difference 10 min after. NRS of anxiety did not differ between the two groups. Conclusion: Based on the ANI, the current study showed that VR did not reach the statistical requirements for a proven non-inferiority vs. Kalinox® in managing pain and anxiety during chest drain removal. Moreover, VR was less effective based on NRS. More studies are needed to determine if VR might have a place in the overall approach to pain and anxiety in intensive care units.

The renin–angiotensin system (RAS) has long been described in the field of cardiovascular physiology as the main player in blood pressure homeostasis. However, other effects have since been described, and include proliferation, fibrosis, and inflammation. To illustrate the immunomodulatory properties of the RAS, we chose three distinct fields in which RAS may play a critical role and be the subject of specific treatments. In oncology, RAS hyperactivation has been associated with tumor migration, survival, cell proliferation, and angiogenesis; preliminary data showed promise of the benefit of RAS blockers in patients treated for certain types of cancer. In intensive care medicine, vasoplegic shock has been associated with severe macro- and microcirculatory imbalance. A relative insufficiency in angiotensin II (AngII) was associated to lethal outcomes and synthetic AngII has been suggested as a specific treatment in these cases. Finally, in solid organ transplantation, both AngI and AngII have been associated with increased rejection events, with a regional specificity in the RAS activity. These elements emphasize the complexity of the direct and indirect interactions of RAS with immunomodulatory pathways and warrant further research in the field. [ABSTRACT FROM AUTHOR]

Lung ultrasound (LUS) has a relatively recent democratization due to the better availability and training of physicians, especially in intensive care units. LUS is a relatively cheap and easy-to-learn and -use bedside technique that evaluates pulmonary morphology when using simple algorithms. During the global COVID-19 pandemic, LUS was found to be an accurate tool to quickly diagnose, triage and monitor patients with COVID-19 pneumonia. This paper aims to provide a comprehensive review of LUS use during the COVID-19 pandemic. The first section of our work defines the technique, the practical approach and the semeiotic signs of LUS examination. The second section exposed the COVID-19 pattern in LUS examination and the difference between the differential diagnosis patterns and the well-correlation found with computer tomography scan findings. In the third section, we described the utility of LUS in the management of COVID-19 patients, allowing an early diagnosis and triage in the emergency department, as the monitoring of pneumonia course (pneumonia progression, alveolar recruitment, mechanical ventilation weaning) and detection of secondary complications (pneumothorax, superinfection). Moreover, we describe the usefulness of LUS as a marker of the prognosis of COVID-19 pneumonia in the fourth section. Finally, the 5th part is focused on describing the interest of the LUS, as a non-ionized technique, in the management of pregnant COVID-19 women. [ABSTRACT FROM AUTHOR]

Background: Out of hospital cardiac arrest (OHCA) patients requiring percutaneous coronary intervention (PCI) are at higher risk of both stent thrombosis and bleeding. The use of aggressive antiplatelet therapy could lead to a higher risk of bleeding in these patients. Indeed, data on glycoprotein IIb/IIIa inhibitor (GPi) use in this specific indication is scarce.Aim: We sought to evaluate the benefit and safety of GPi use in OHCA patients requiring PCI.Methods and Results: Between January 2007 and December 2017, we retrospectively included all consecutive patients treated with PCI for an OHCA from cardiac cause. Clinical, procedural data and in-hospital outcomes were collected. Three hundred and eighty-five patients were included. GPi were administrated in 41.3% of cases (159 patients). Patients who received GPi were younger, had less prior PCI, more often a TIMI 0 or 1 flow before PCI and thromboaspiration use. There were no differences regarding in-hospital definite stent thrombosis among the two groups (11.9% in the GPi group vs 7.1% in the non-GPi group, p = 0.10) or in-hospital mortality (48.6% vs 49.3%, p = 0.68). The incidence of any bleeding (33.3% vs. 19.6%; p = 0.002), and major bleeding (BARC 3-5) (21.9% vs. 16.8%; p = 0.007) was significantly higher in patients receiving GPi. Indeed, using multivariate analysis, GPi use was predictor of major bleeding (OR: 1.81; 95% CI: 1.06-3.08; p = 0.03).Conclusions: In patients treated with PCI for OHCA from cardiac cause, GPi use was associated with an increased risk of major bleeding events, without difference on in-hospital stent thrombosis or death.

Data is scarce on hemorrhagic and thrombotic complications in patients with ST-elevation myocardial infarction (STEMI) associated with out-of-hospital cardiac arrest (OHCA). This is a monocentric, retrospective study conducted from January 2012 to December 2017 in a tertiary university hospital, which serves as a cardiac arrest center for a large urban area. Over the study period, all consecutive patients who were treated with stent implantation for STEMI with or without OHCA were included. Baseline characteristics, treatments, hemorrhagic and thrombotic events were compared between STEMI patients with and without OHCA. Univariate and multivariate analysis were performed in order to identify predictors of 30-day mortality, occurrence of major bleeding (MB), and early stent thrombosis (ST). A total of 549 patients treated for STEMI without OHCA and 146 patients for STEMI with OHCA were included. The incidence of definite ST and MB after coronary angioplasty was significantly higher in patients with OHCA (2.6% vs. 7.5%, p = 0.004 and 3.3% vs. 19.2%, p < 0.001, respectively). Independent predictors of MB in OHCA patients were anticoagulation therapy (HR = 3.11, 95%CI [1.22–7.98], p = 0.02) and the use of glycoprotein IIb/IIIa inhibitors (HR = 4.16, 95%CI [1.61–10.79], p = 0.003). Independent predictors of mortality in OHCA patients were age (HR = 1.05, 95%CI [1.02–1.09], p = 0.004) and ST (HR = 5.62, 95%CI [1.61–19.65], p = 0.007, with a protective effect of new anti-P2Y12 treatments (HR = 0.20, 95%CI [0.08-0.46], p < 0.001). Patients treated for STEMI associated with OHCA are at higher-risk of ST and MB than those who did not experience cardiac arrest. In this subset of patients, prospective studies are needed to better evaluate the balance of thrombosis and hemorrhage. [ABSTRACT FROM AUTHOR]
