Pulmonary artery elastance as a predictor of hospital mortality in heart failure cardiogenic shock. ESC Heart Fail 2024. [PMID: 38710587 DOI: 10.1002/ehf2.14817] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 03/20/2024] [Accepted: 04/02/2024] [Indexed: 05/08/2024] Open
Abstract
AIMS The initial bundle of cares strongly affects haemodynamics and outcomes in acute decompensated heart failure cardiogenic shock (ADHF-CS). We sought to characterize whether 24 h haemodynamic profiling provides superior prognostic information as compared with admission assessment and which haemodynamic parameters best predict in-hospital death. METHODS AND RESULTS All patients with ADHF-CS and with available admission and 24 h invasive haemodynamic assessment from two academic institutions were considered for this study. The primary endpoint was in-hospital death. Regression analyses were run to identify relevant predictors of study outcome. We included 127 ADHF-CS patients [65 (inter-quartile range 52-72) years, 25.2% female]. Overall, in-hospital mortality occurred in 26.8%. Non-survivors were older, with greater CS severity. Among admission variables, age [odds ratio (OR) = 1.06; 95% confidence interval (CI): 1.02-1.11; Padj = 0.005] and CPIRAP (OR = 0.62 for 0.1 increment; 95% CI: 0.39-0.95; Padj = 0.034) were found significantly associated with in-hospital death. Among 24 h haemodynamic univariate predictors of in-hospital death, pulmonary elastance (PaE) was the strongest (area under the curve of 0.77; 95% CI: 0.68-0.86). PaE (OR = 5.98; 95% CI: 2.29-17.48; Padj < 0.001), pulmonary artery pulsatility index (PAPi, OR = 0.77; 95% CI: 0.62-0.92; Padj = 0.013) and age (OR = 1.06; 95% CI: 1.02-1.11; Padj = 0.010) were independently associated with in-hospital death. Best cut-off for PaE was 0.85 mmHg/mL and for PAPi was 2.95; cohort phenotyping based on these PaE and PAPi thresholds further increased in-hospital death risk stratification; patients with 24 h high PaE and low PAPi exhibited the highest in-hospital mortality (56.2%). CONCLUSIONS Pulmonary artery elastance has been found to be the most powerful 24 h haemodynamic predictor of in-hospital death in patients with ADHF-CS. Age, 24 h PaE, and PAPi are independently associated with hospital mortality. PaE captures right ventriclar (RV) afterload mismatch and PAPi provides a metric of RV adaptation, thus their combination generates four distinct haemodynamic phenotypes, enhancing in-hospital death risk stratification.

Abstract
With the general population aging, both life expectancy and the number of left ventricular assist device (LVAD) implantations in elderly patients are growing. Nevertheless, their perceived long-term quality of life, including psychological aspects, coupled with the respective caregiver's burden, remain under-reported. In light of the rising number of octogenarians with LVAD who necessitate broader healthcare provider involvement, we assessed the long-term quality of life, as defined by both the 36-item short-form health (SF-36) survey and the EuroQol 5 dimensions, 5-level questionnaire (EQ-5D-5L)-including the visual analog scale-in octogenarian LVAD patients who had received treatment at our institution. Additionally, we evaluated the psychological health of octogenarian LVAD patients using the psychological general well-being index (PGWBI), alongside their caregivers' well-being through the 22-item version of the Zarit Burden Interview (ZBI). Of 12 octogenarian LVAD patients, 5 were alive and willing to answer questionnaires. Mean age at implant was 74 ± 2 years. Median follow-up was 2464 (IQR = 2375-2745) days. Although variable, the degree of health and psychological well-being perceived by octogenarian patients with LVAD was "good." Interestingly, the burden of assistance reported by caregivers, though relevant, was greatly varied, suggesting the need to better define and address psychological long-term aspects related to LVAD implantation for both patients and caregivers with a broad-spectrum approach.

European practices on antithrombotic management during percutaneous mechanical circulatory support in adults: A survey of the Association for Acute CardioVascular Care (ACVC) of the ESC and the European branch of the Extracorporeal Life Support Organization (EuroELSO). EUROPEAN HEART JOURNAL. ACUTE CARDIOVASCULAR CARE 2024:zuae040. [PMID: 38529950 DOI: 10.1093/ehjacc/zuae040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 03/20/2024] [Accepted: 03/22/2024] [Indexed: 03/27/2024]
Abstract
BACKGROUND Bleeding and thrombotic complications compromise outcomes in patients undergoing percutaneous mechanical circulatory support (pMCS) with veno-arterial extracorporeal membrane oxygenation (V-A ECMO) and/or microaxial flow pumps like the Impella™. Antithrombotic practices are an important determinant of the coagulopathic risk, but standardization in the antithrombotic management during pMCS is lacking. This survey outlines European practices in antithrombotic management in adults on pMCS, making an initial effort to standardize practices, inform future trials, and enhance outcomes. METHODS This online cross-sectional survey was distributed through digital newsletters and social media platforms by the Association of Acute Cardiovascular Care and the European branch of the Extracorporeal Life Support Organization. The survey was available from April 17th to May 23rd, 2023. The target population were European clinicians involved in care for adults on pMCS. RESULTS We included 105 responses from 26 European countries. Notably, 72.4% of the respondents adhered to locally established anticoagulation protocols, with unfractionated heparin (UFH) being the predominant anticoagulant (Impella™: 97.0% and V-A ECMO: 96.1%). A minority, 10.8% and 14.5%, respectively, utilized anti-factor-Xa assay with activated partial thromboplastin time in parallel for UFH monitoring during Impella™ and V-A ECMO support. Anticoagulant targets varied across institutions. Following acute coronary syndrome without percutaneous coronary intervention (PCI), 54.0% and 42.7% administered dual antiplatelet therapy during Impella™ and V-A ECMO support, increasing to 93.7% and 84.0% after PCI. CONCLUSIONS Substantial heterogeneity in antithrombotic practices emerged from participants' responses, potentially contributing to variable device-associated bleeding and thrombotic complications.

Abstract
We reported a case of blood culture-negative infective endocarditis on a native valve, where the clinical presentation was exclusively related to extensive cerebral ischemia secondary to multiple systemic septic cardioembolic events. The cause was ascribed to subacute Bartonella henselae infection, presumably transmitted by cat scratch, documented by positive serologic findings.

Abstract
OBJECTIVES To ascertain whether invasive assessment of coronary physiology soon after recanalisation of the culprit artery by primary percutaneous coronary intervention is associated with the development of microvascular obstruction by cardiac magnetic resonance in patients with ST-segment elevation myocardial infarction (STEMI). METHODS Between November 2020 and December 2021, 102 consecutive patients were prospectively enrolled in five tertiary centres in Italy. Coronary flow reserve (CFR) and index of microvascular resistance (IMR) were measured in the culprit vessel soon after successful primary percutaneous coronary intervention. Optimal cut-off points of IMR and CFR to predict the presence of microvascular obstruction were estimated, stratifying the population accordingly in four groups. A comparison with previously proposed stratification models was carried out. RESULTS IMR>31 units and CFR≤1.25 yielded the best accuracy. Patients with IMR>31 and CFR≤1.25 exhibited higher microvascular obstruction prevalence (83% vs 38%, p<0.001) and lower left ventricular ejection fraction (45±9% vs 52±9%, p=0.043) compared with those with IMR≤31 and CFR>1.25, and lower left ventricular ejection fraction compared with patients with CFR≤1.25 and IMR≤31 (45±9% vs 54±7%, p=0.025). Infarct size and area at risk were larger in the former, compared with other groups. CONCLUSIONS IMR and CFR are associated with the presence of microvascular obstruction in STEMI. Patients with an IMR>31 units and a CFR≤1.25 have higher prevalence of microvascular obstruction, lower left ventricular ejection fraction, larger infarct size and area at risk.

Abstract
Percutaneous ventricular assist devices (pVADs) are increasingly being used because of improved experience and availability. The Impella (Abiomed), a percutaneous microaxial, continuous-flow, short-term ventricular assist device, requires meticulous postimplantation management to avoid the 2 most frequent complications, namely, bleeding and hemolysis. A standardized approach to the prevention, detection, and treatment of these complications is mandatory to improve outcomes. The risk for hemolysis is mostly influenced by pump instability, resulting from patient- or device-related factors. Upfront echocardiographic assessment, frequent monitoring, and prompt intervention are essential. The precarious hemostatic balance during pVAD support results from the combination of a procoagulant state, due to critical illness and contact pathway activation, together with a variety of factors aggravating bleeding risk. Preventive strategies and appropriate management, adapted to the impact of the bleeding, are crucial. This review offers a guide to physicians to tackle these device-related complications in this critically ill pVAD-supported patient population.

Abstract
BACKGROUND AND AIM Measurement of cardiac index (CI) is crucial in the hemodynamic assessment of critically ill patients in the intensive care unit (ICU). The most reliable trans-thoracic echocardiography (TTE) technique for CI estimation is the left ventricular outflow tract (LVOT) Doppler method that requires, among other parameters, the LVOT cross-sectional area (CSA) measurement. However, inherent and practical disadvantages, mostly related to the ICU setting, hamper LVOT-CSA assessment. In this study, we aimed to validate a simplified formula, leveraging on LVOT-velocity time integral (VTI) and heart rate (HR) only, for non-invasive estimation of CI in ICU patients. METHODS AND RESULTS We prospectively enrolled 50 consecutive patients admitted to our ICU requiring pulmonary artery catheterization (PAC) over a one-year period. For each patient we measured the CI by PAC (CIPAC) and TTE. The latter was obtained both with the "traditional formula" (traditional CITTE), requiring LVOT-CSA assessment, and our new "simplified formula" (simplified CITTE). The correlation between the simplified CITTE and CIPAC was strong (r = 0.81) and resulted significantly greater than the traditional CITTE and CIPAC correlation (r = 0.70; p < 0.05 for Pearson r coefficients comparison). Both TTE-based CI showed an acceptable agreement (+0.19 ± 0.48 L/min/m2 for simplified CITTE and - 0.18 ± 0.58 L/min/m2 for traditional CITTE) with the reference CIPAC. CONCLUSION In this study, we validated a practical approach, leveraging on TTE LVOT-VTI and HR only, for non-invasive estimation of CI in ICU patients.

Abstract
Abstract
Introduction
In cardiogenic shock (CS) patients with temporary mechanical circulatory support (TMCS) the weaning process is crucial to verify patients’ myocardial recovery or device dependency. To date, there are no specific guidelines on weaning strategies.
Hypothesis
We investigated clinical predictors of successful weaning from TMCS and developed with them a novel prognostic scoring system.
Methods
Eighty CS patients (62.5 ± 11.8 years, 86.2% male, 63.7% with ACS) with Impella support were evaluated. Hemodynamic, echocardiographic and laboratory data were collected at admission (T0), 24 (T1), 48 (T2), 96 (T3) hours after TMCS implantation. CS patients were classified according to successful or unsuccessful weaning, defined as hemodynamic/myocardial recovery, and death/need for LVAD/heart transplant, respectively. Independent predictors of weaning and their discriminating cut-off values were identified. Finally, a prognostic weaning score (W-Score) was derived.
Results
Thirty-eight (47.5%) CS patients showed successful (SW-group) while 42 (52.5%) unsuccessful (UW-group) weaning from TMCS. Clinical characteristics were similar between the two groups. SW-group showed higher T1, T2, T3 LVEF (p=0.013, p=0.001, p=0.001), T1 CPO (p=0.04), T2 MAP (p=0.019) and lower T1, T2 inotropic score values (p=0.001, p=0.001), T2 HR and PCWP (p=0.01, p=0.008), T1 and T3 creatinine (p=0.018, p=0.009), lactate (p=0.009, p=0.002) and NT-proBNP (p=0.017, p=0.001). T1 LVEF, NT-proBNP and inotropic score together with T3 creatinine and lactate resulted independent predictors of SW (p<0.05). T1 LVEF ≥ 10%, T1 inotropic score ≤ 8, T1 NT-proBNP ≤ 8068 ng/L, T3 lactate ≤ 1,59 mmol/L, T3 creatinine ≤ 1,76 mg/dl identified patients with SW (overall, AUC ≥0.7, p<0.05). W-Score was developed enabling SW with a cut-off score ≥ 7 (80% sensitivity, 85% specificity, AUC 0.92, p <0.001).
Conclusions
W-Score, based on T1 LVEF/inotropic score/NT-proBNP, T3 creatinine/lactate values may be useful to identify CS patients undergoing successful weaning from TMCS.

824 HEMODYNAMIC EFFECTS OF LEVOSIMENDAN IN PATIENTS WITH ACUTE HEART FAILURE AND SEVERE RENAL FAILURE. Eur Heart J Suppl 2022.

Abstract
Abstract
Background
The inodilator levosimendan has shown improved outcomes in acute heart failure (AHF) and cardiac surgery. Its hemodynamic effect is persistent, owing to a long (70-80 hours) elimination half-life of its active metabolites. No robust data is available of the use of levosimendan in patients with severe renal failure (SRF), thus its use is contraindicated in patients with estimated glomerular filtration rate (eGFR≤30 mL/min).
Hypothesis
Different pharmacokinetics due to renal failure may alter levosimendan active metabolites elimination, causing more pronounced hemodynamic effects. We aimed to characterize the hemodynamic effect of levosimendan in a real-world cohort of SRF patients.
Methods
We reviewed patients who received levosimendan (12.5 mg) for AHF or cardiogenic shock in our CICU (N=132), excluding those without invasive hemodynamics (n=85), and those without data before and during levosimendan infusion (n=11), a total of 36 patients were finally included in this analysis. We compared hemodynamics before and during levosimendan infusion in the study cohort with CKD-EPI eGFR≤30 mL/min/1.73 m2 or CRRT and those without.
Results
Patients with low eGFR (n=11) were older, they had similar LVEF and invasive hemodynamics before levosimendan infusion to the higher eGFR cohort. Visual inspection of the LOESS regression plots (Figure) revealed an higher drop in mean arterial pressure (MAP) and diastolic arterial pressure (DAP) in the low eGFR cohort. The maximum drop was observed at day 4 from levosimendan initiation, invasive hemodynamics at this timepoint revealed a lower DAP (44.6±8.8 vs 62.6±11.9 mmHg; p=0.014) and a tendentially lower MAP (73.6±5.5 vs 84.4±11.5 mmHg; p=0.079) while systolic arterial pressure (125.0±24.6 vs 121.3±21.8 mmHg; p=0.779), cardiac index (2.1±0.5 vs 2.5±0.7 L/m2; p=0.211), and mean pulmonary arterial pressure (25.8±8.3 vs 24.8±9.6 mmHg; p=0.844) did not differ between groups. In-hospital death was not different in the two cohorts (27.3 vs 16.0%; p=0.650).
Conclusions
Patient with eGFR≤30 mL/min/1.73 m2 demonstrated a higher drop in DAP and MAP four days after levosimendan infusion start, without impact on hospital mortality. These findings may suggest a more pronounced hemodynamic effect of levosimendan in patients with SRF, possibly due to altered pharmacokinetics of its active metabolites.

Abstract
Abstract
Background
Intra-Aortic Balloon Pump (IABP) efficacy is critically affected by the inflation/deflation timing. Balloon deflation may cause a sucking effect, and a steal phenomenon on carotid flow. Delaying IABP deflation reduces the degree of this flow reversal, but at the same time exposes patients to the risk of increased proto-systolic afterload with detrimental effects on the LV.
Hypothesis
To investigate the effects of a delayed IABP deflation timing on cerebral blood flow and LV hemodynamics.
Methods
We prospectively evaluated 20 consecutive patients who received transfemoral IABP for cardiogenic shock (CS). Central aortic pressures (augmented diastolic [ADP], end-diastolic [EDP], assisted systolic [ASP] and mean aortic [MAP] pressures) were recorded from the IABP console simultaneously with ultrasound data. First ultrasound and haemodynamic measurements were collected during conventional IABP deflation timing (balloon deflation completed before onset of LV systole by automated ECG gating). Then, IABP deflation was manually delayed to the beginning of the QRS (early LV systole). After adjustment, counterpulsation was performed for a minimum of 2 minutes to achieve steady hemodynamics, then the same ultrasound and haemodynamic measurements were recollected.
Results
Mean age was 67±13 years, LVEF was 25±11%. At the carotid ultrasound, the delayed deflation increased the net forward velocity time integral (VTI) in the common carotid artery (18±9 vs 15±8 cm; p=0.001), by reducing the end-diastolic backward VTI (1±1 vs 4±2 cm; p<0.001) while having no effect on the overall forward VTI (19±9 vs 19±9 cm; p=0.294). Specifically, the delayed deflation increased the diastolic forward VTI (12±5 vs 10±4 cm]; p<0.001) while decreasing the systolic forward VTI (7±4 vs 9±4 cm]; p<0.005). On central aortic hemodynamics, the delayed deflation decreased the ASP (91±21 vs 97±20 mmHg; p=0.001), increased the EDP (60±11 vs 48±9 mmHg; p<0.001), the ADP (123±19 vs 119±19 mmHg; p<0.001) and the MAP (89±14 vs 80±12 mmHg; p<0.001). On echocardiography, the delayed deflation increased the LVOT VTI (15±4 vs 13±4 cm; p<0.001), decreased LV ejection time (202±44 vs 211±43 ms; p=0.005) but did not affect the isovolumetric contraction time (119±56 vs 119±58 ms; p=0.989), eventually reducing the total duration of LV systole (321±54 vs 330±50 ms; p=0.009).
Conclusions
In our cohort, a delayed IABP deflation strategy, evaluated by a multi-parametric yet relatively simple approach, demonstrated to be safe and was associated with both an increase cerebral perfusion and an improvement in cardiac mechanics.

Abstract
Abstract
Background
Acute heart failure (AHF) with left ventricle (LV) dysfunction is characterized by a condition of afterload mismatch without preload reserve. LV ejection fraction (LVEF) and stroke volume (SV) become thus dependent on the afterload. Owing to its arteriolar vasodilator properties, sodium nitroprusside (SNP) may reduce LV afterload and result particularly beneficial in this setting, improving LV ejection and ventriculo-arterial coupling (VAC).
Hypothesis
We aimed to assess the effect of SNP on LV afterload (arterial elastance, Ea), LV contractility (end-systolic elastance, Ees) and VAC (Ea/Ees ratio) in AHF patients.
Methods
Patients with AHF receiving SNP were prospectively enrolled and underwent Ea and Ees estimation with a single-beat echocardiographic method, before and after SNP infusion. The method was described by Chen et al (J Am Coll Cardiol, 2001) and Kelly et al (Circulation, 1992). Echocardiography was analyzed by a physician blinded to the images timing.
Results
A total of 36 AHF patients [69% male, age 70 (68, 76) years] received SNP infusion and were enrolled. Patients were admitted for acute coronary syndrome (47%) and for worsening heart failure (53%). SNP median dose was low: 0.30 (0.21-0.57) mcg/kg/min.
SNP led to a trend to SBP reduction [140 (131-150) vs 158 (140-168) mmHg; p=0.002]. Heart rate did not change: 84 (75, 92) vs 83 (72, 94) bpm; p=0.800. Afterload (Ea) was reduced following SNP infusion: 2.2 (1.9, 2.7) vs 2.8 (2.4, 3.4) mmHg/mL; p<0.001. LV contractility (Ees) was unchanged: 1.3 (0.8, 2.2) vs 1.5 (0.9, 3.4) mmHg/mL; p=0.13. End-diastolic volume did not change: 148 (110, 205) vs 146 (108, 213) mL; p=0.880. These effects led to an increased SV: 56 (47, 67) vs 50 (38, 56) mL; p<0.001; p<0.001 and, subsequently to an increased EF [40 (30, 50) vs 30 (20, 40)%; p<0.001]. The VAC did not significantly change after SNP infusion: 1.5 (0.9-2.8) vs 1.6 (0.9-2.7); p=0.64.
Conclusion
In this report on consecutive AHF, low-dose SNP did not significantly affect VAC but led to a significant reduction in LV afterload and to a significant increase in SV and LVEF.

Impella RP for Patients with Acute Right Ventricular Failure and Cardiogenic Shock: A Subanalysis from the IMP-IT Registry. J Pers Med 2022; 12:jpm12091481. [PMID: 36143266 PMCID: PMC9506315 DOI: 10.3390/jpm12091481] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 09/01/2022] [Accepted: 09/05/2022] [Indexed: 11/16/2022] Open
Abstract
The use of percutaneous right ventricular assist devices (pRVADs) to support patients with right ventricular (RV)-predominant cardiogenic shock (CS) refractory to optimal medical therapy is increasing progressively, and the Impella RP is the first FDA-approved pRVAD in such a clinical scenario. The aim of the present study is to report the outcomes of patients treated with Impella RP in the IMP-IT (IMPella Mechanical Circulatory Support Device in Italy) registry, a multicenter registry that evaluated the trends in use and clinical outcomes of the Impella in the setting of CS and high-risk percutaneous coronary intervention in Italy. A total of 15 patients who received Impella RP were enrolled. In 40% of the patients, the main cause was ST-segment elevation myocardial infarction. A total of 40% of patients required biventricular support with a left Impella. Device-related complications were reported in 46.7% of patients. Overall, the in-hospital mortality was 46.7%, whereas the one-year mortality was 53.3%. The composite rate of all-cause death, heart failure (HF) hospitalization, left ventricular assist device (LVAD) and heart transplant at one year was 60%. The Impella RP has favorable survival outcomes in RV-predominant cardiogenic shock. However, the device-related complications are frequent and should be carefully weighed when considering escalation to Impella RP.

Prognostic value of right atrial pressure-corrected cardiac power index in cardiogenic shock. ESC Heart Fail 2022; 9:3920-3930. [PMID: 35950538 PMCID: PMC9773720 DOI: 10.1002/ehf2.14093] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 06/17/2022] [Accepted: 07/18/2022] [Indexed: 01/19/2023] Open
Abstract
AIM The pulmonary artery catheter (PAC)-derived cardiac power index (CPI) has been found of prognostic value in cardiogenic shock (CS) patients. The original CPI equation included the right atrial pressure (RAP), accounting for heart filling pressure as a determinant of systolic myocardial work, but this term was subsequently omitted. We hypothesized that the original CPI formula (CPIRAP ) is superior to current CPI for risk stratification in CS. METHODS AND RESULTS A single-centre cohort of 80 consecutive Society for Cardiovascular Angiography and Interventions (SCAI) B-D CS patients with available PAC records was included. Overall in-hospital mortality was 21.3%. Results showed CPIRAP to be the strongest haemodynamic predictor of in-hospital death (padj = 0.038), outperforming CPI [area under the receiver operating characteristic (ROC) curves: 0.726 and 0.673, P-for-difference = 0.025]. When the population was stratified according to the identified CPIRAP (0.28 W/m2 ) and accepted CPI (0.32 W/m2 ) thresholds, the cohort with discordant indexes (low CPIRAP and high CPI) comprised a group of 13 patients featuring a congested phenotype with frequent right ventricle or biventricular involvement. In this group, in-hospital mortality was high (30.8%) similar to those with concordant low CPI and CPIRAP . CONCLUSION Incorporating RAP in CPI calculation (CPIRAP ) improves the prognostic yield in patients with CS SCAI B-D. A cut-off of 0.28 W/m2 identifies patients at higher risk of in-hospital mortality. The improved prognostic value of CPIRAP may derive from identification of patients with more intravascular congestion who may experience substantial in-hospital mortality, uncaptured by the commonly used CPI equation.

Abstract
Background In contemporary Cardiac Intensive Care Unit (CICU), bedside intra‐aortic balloon pump (IABP) insertion under echocardiographic guidance may be an attractive option for selected patients with cardiogenic shock (CS). Currently available data on this approach are limited. Aim This study aimed to assess the feasibility and safety of bedside IABP insertion, as compared to fluoroscopic‐guided insertion in the Catheterization Laboratory (CathLab), and to describe the clinical features of patients receiving bedside IABP insertion using a standardized technique in real‐world CICU practice. Methods We prospectively evaluated all patients admitted the CICU who received transfemoral IABP between June 2020 and October 2021. The overall study cohort was divided according to implant strategy in bedside and CathLab groups. The primary outcome was correct radiographic IABP positioning at the first bedside chest X‐ray obtained after insertion. Secondary outcomes included IABP‐related complications. Results Among 115 patients, bedside IABP insertion was performed in 35 (30.4%) cases, mainly presenting with CS‐related to acute decompensated heart failure (ADHF) (68.6 vs 33.8%; p < 0.001), with lower LVEF, higher proportion of right ventricular involvement and higher need of inotropes/vasopressors, compared to those receiving CathLab insertion. Bedside IABP insertion resulted feasible and safe, with similar rates of correct IABP positioning (82.9 vs. 82.5%; p = 0.963) and IABP‐related major vascular complications (5.7 vs. 5.0%; p = 0.874), as compared to CathLab positioning. Conclusion This study suggests the feasibility and safety of bedside IABP insertion, which could be of relevant interest in patients with ADHF‐related CS who may not need coronary angiography or other urgent CathLab procedures.

Abstract
Trials on intra-aortic balloon pump (IABP) use in cardiogenic shock related to acute myocardial infarction have shown disappointing results. The role of IABP in cardiogenic shock treatment remains unclear, and new (potentially more potent) mechanical circulatory supports with arguably larger device profile are emerging. A reappraisal of the physiological premises of intra-aortic counterpulsation may underpin the rationale to maintain IABP as a valuable therapeutic option for patients with acute decompensated heart failure and tissue hypoperfusion. Several pathophysiological features differ between myocardial infarction- and acute decompensated heart failure-related hypoperfusion, encompassing cardiogenic shock severity, filling status, systemic vascular resistances rise, and adaptation to chronic (if preexisting) left ventricular dysfunction. IABP combines a more substantial effect on left ventricular afterload with a modest increase in cardiac output and would therefore be most suitable in clinical scenarios characterized by a disproportionate increase in afterload without profound hemodynamic compromise. The acute decompensated heart failure syndrome is characterized by exquisite afterload-sensitivity of cardiac output and may be an ideal setting for counterpulsation. Several hemodynamic variables have been shown to predict response to IABP within this scenario, potentially guiding appropriate patient selection. Finally, acute decompensated heart failure with hypoperfusion may frequently represent an end stage in the heart failure history: IABP may provide sufficient hemodynamic support and prompt end-organ function recovery in view of more definitive heart replacement therapies while preserving ambulation when used with a transaxillary approach.

Abstract
Abstract
Background
Non pharmaceutical interventions (NPIs) put in place to reduce the spread of Sars-Cov-2 had an impact also on other infections. Aim of this research is to describe the incidence of other infections and vaccination coverage rate (VCR) in Lombardy region from 2018 to 2020.
Methods
We analysed data coming from the regional surveillance system of notifiable infectious diseases and vaccination registry from 2018 to 2020.
Results
13206 infectious diseases' cases were notified in 2020 compared to 36847 in 2019 and 42610 in 2018, this corresponding to, respectively, a 64.1% and 69% decrease. Some interesting data:
measles; 24 cases in 2020, 542 in 2019 and 220 in 2018, with an incidence rate (IR) per 100.000 respectively of 0,2; 5,4 and 2,2; chicken pox; 2357 cases in 2020, 13478 in 2019 and 19463 in 2018 (IR 23,5; 134,3; 193,9) tubercolosis; 586 in 2020, 857 in 2019 and 945 in 2018 (IR 5,8; 8,6; 9,4) invasive bacterial diseases; 378 in 2020, 890 in 2019 and 882 in 2018 (IR 3,7;8,8;8,7) infectious diarrhea; 2080 in 2020, 3716 in 2019 and 4347 in 2018 (IR 20,7; 37,1; 43,3) legionellosis cases; 806 in 2020, 1051 in 2019 and 1096 in 2018 (IR 8; 10,5; 10,9) arbovirus infections (chikunguya, dengue, west nile, zika) were 118, in 2020, 126 in 2019 and 8 in 2018 (IC 1,2; 1,3; 0,1)
In 2020 VCR at 24 months of age remained above 95% for hexavalent and measles-mumps-rubella vaccination while there was a decline for others vaccines.
Conclusions
During the COVID-19 outbreak in 2020 there was a decline in all notified infectious diseases compared to the previous years, likely due to massive NPIs adoption, as well as, possibly, to decreased access to care and preventive services that caused difficulties to the surveillance system to detect notifiable infectious diseases. VCRs were still high for most important vaccines while there was a decline for other vaccines as evidence of the impact of the pandemic on vaccination activities.
Key messages
NPIs had a deep impact on the reduction of airborne diseases. The decline for non-airborne infections is likely due to NPIs and limitations in the access to the healthcare system.

Abstract
BACKGROUND Concurrent evidence about cardiogenic shock (CS) characteristics, treatment and outcome does not represent a global spectrum of patients and is therefore limited. The aim of this study was to investigate these regional differences. METHODS To investigate regional differences in presentation characteristics, treatments and outcomes of patients treated with all types of cardiogenic shock (CS) in a single calendar year on a multi-national level. Consecutive patients from 19 tertiary care hospitals in 13 countries with CS who were treated between January 1, 2018 and December 31, 2018 were enrolled in this study. RESULTS In total, 699 cardiogenic shock patients were included in this study. Of these patients, 440 patients (63%) were treated in European hospitals and 259 (37%) were treated in Non-European hospitals. Female patients (P<0.01) and patients with a previous myocardial infarction (P=0.02) were more likely to present at Non-European hospitals; whereas older patients (P=0.01) and patients with cardiogenic shock due to acute heart failure (P<0.01) were more likely to present at European hospitals. Vasopressor use was more likely in Non-European hospitals (P=0.04), whereas use of mechanical circulatory support (MCS) was more likely in European hospitals (P<0.01). Despite adjustment for relevant confounders, 30-day in-hospital mortality risk was comparably high in CS patients treated in European vs. Non-European hospitals (hazard ratio 1.08, 95% CI 0.84-1.39, P=0.56). CONCLUSION Despite marked heterogeneity in characteristics and treatment of CS patients, including fewer use of MCS but more frequent use of vasopressors in Non-European hospitals, 30-day in-hospital mortality did not differ between regions.

Abstract
There has been a significant increase in the use of short-term percutaneous ventricular assist devices (pVADs) as acute circulatory support in cardiogenic shock and to provide haemodynamic support during interventional procedures, including high-risk percutaneous coronary interventions. Although frequently considered together, pVADs differ in their haemodynamic effects, management, indications, insertion techniques, and monitoring requirements. This consensus document summarizes the views of an expert panel by the European Association of Percutaneous Cardiovascular Interventions (EAPCI) and the Association for Acute Cardiovascular Care (ACVC) and appraises the value of short-term pVAD. It reviews the pathophysiological context and possible indications for pVAD in different clinical settings and provides guidance regarding the management of pVAD based on existing evidence and best current practice.

Abstract
Extracorporeal membrane oxygenation (ECMO) represents a therapeutic option for cardiopulmonary support in patients with high-risk pulmonary embolism (PE); however, no definite consensus exists on ECMO use in high-risk PE. Hence, we aim to provide insights into its real-world use pooling together all available published experiences. We performed a systematic review and pooled analysis of all published studies (up to April 17, 2020) investigating ECMO support in high-risk PE. All studies including at least four patients were collectively analyzed. Study outcomes were early all-cause death (primary endpoint) and relevant in-hospital adverse events. A total of 21 studies were included in the pooled analysis (n = 635 patients). In this population (mean age 47.8 ± 17.3 years, 44.5% females), ECMO was indicated for cardiac arrest in 62.3% and immediate ECMO support was pursued in 61.9% of patients. Adjunctive reperfusion therapies were implemented in 57.0% of patients. Pooled estimate rate of early all-cause mortality was 41.1% (95% CI 27.7%-54.5%). The most common in-hospital adverse event was major bleeding, with an estimated rate of 28.6% (95%CI 21.0%-36.3%). At meta-regression analyses, no significant impact of multiple covariates on the primary endpoint was found. In this systematic review of patients who received ECMO for high-risk PE, pooled all-cause mortality was 41.1%. Principal indication for ECMO was cardiac arrest, cannulation was chiefly performed at presentation, and major bleeding was the most common complication.

Abstract
Abstract
Background
High-risk acute pulmonary embolism (PE) is burdened by a mortality as high as 65%. VenoArterial ExtraCorporeal Membrane Oxygenation (VA-ECMO) may offer a cardiopulmonary support and a precious time window to ensure pulmonary reperfusion therapies. No definite consensus exists on the use of VA-ECMO in high-risk PE patients as only sparse observational studies are available yielding conflicting outcomes.
Purpose
To provide insights on the use of ECMO in acute high-risk PE pooling together all available published experiences to date.
Methods
Two authors (LB, AB) searched PubMed, Embase, BioMedCentral and Google Scholar, from inception to 18/09/2019. All published clinical studies investigating ECMO support in patients with high-risk acute PE were evaluated for inclusion.
Results
Literature search identified 384 observational studies: a total of 66 were included for 584 acute high-risk PE patients receiving ECMO support. Mean age was 46.8±16.8 years (44% female). Most patients presented with cardiac arrest (56%) or obstructive shock (42%). Diagnosis of PE was confirmed by computed tomography (CT) in 72%, performed before ECMO cannulation in 65%. Echocardiography was obtained in 89%. Right ventricle dilatation or dysfunction was found in 90% and 87%. ECMO was primarily employed as upfront treatment (63%), in the VA-ECMO configuration (94%). ECMO was equally employed in conjunction with interventional/surgical pulmonary reperfusion treatments (38%), with thrombolysis (35%) and without adjunctive procedures (40%). Mean ECMO support duration was 100.3±12.9 hours. Notably, 92% received thrombolysis before ECMO cannulation. ECMO bailout implant was mostly adopted in patients receiving thrombolysis (81% vs 19%; p=0.010), as a rescue therapy. Most common reperfusion procedures were surgical embolectomy (28%), catheter-directed thrombolysis (12%) and transcatheter embolectomy (12%). The majority of these procedures (81%) took place after ECMO cannulation. Mean total hospital stay was 17.8±11.6 days. Hospital survival rate was 54% and did not differ in upfront vs bailout ECMO (p=0.184) and between thrombolysis, interventional procedure and ECMO alone recipients (p=0.423). Neurologic death and non-fatal neurologic injury occurred both in 10%. Most patients (70%) were successfully weaned off ECMO, while 30% died on support and 7% died after ECMO removal. Acute kidney injury was the most common complication (47%). Major bleeding occurred in 19% and was fatal for 5%. Patients undergoing thrombolysis had a tendency towards higher rates of major bleeding (48% vs 23%; p=0.05). At a mean follow-up of 365.0 (IQR 202.5–365.9) days, overall survival rate was 85% in those surviving hospitalization.
Conclusions
In this pooled population consisting mostly of cardiac arrest/obstructive shock PE patients, ECMO strategy was associated with acceptable in-hospital survival and was frequently used in conjunction with other reperfusion treatments.

Abstract
Despite optimal combination of guideline-directed anti-ischemic therapies and myocardial revascularization, a substantial proportion of patients with stable coronary artery disease continues to experience disabling symptoms and is often referred as "no-option." The appraisal of the pathways linking ischemia to symptom perception indicates a complex model of heart-brain interactions in the generation of the subjective anginal experience and inspired novel approaches that may be clinically effective in alleviating the angina burden of this population. Conversely, the prevailing ischemia-centered view of angina, with the focus on traditional myocardial revascularization as the sole option to address ischemia on top of medical therapy, hinders the experimental characterization and broad-scale clinical implementation of strongly needed therapeutic options. The interventionist, often the first physician to establish the diagnosis of refractory angina pectoris (RAP) following coronary angiography, should be aware of the numerous emerging technologies with the potential to improve quality of life in the growing population of RAP patients. This review describes the current landscape and the future perspectives on nonpharmacological treatment technologies for patients with RAP, with a view on the underlying physiopathological rationale and current clinical evidence.

Abstract
OBJECTIVE To assess the prevalence, characteristics and prognostic value of pulmonary hypertension (PH) and right ventricular dysfunction (RVD) in hospitalised, non-intensive care unit (ICU) patients with coronavirus disease 2019 (COVID-19). METHODS This single-centre, observational, cross-sectional study included 211 patients with COVID-19 admitted to non-ICU departments who underwent a single transthoracic echocardiography (TTE). Patients with poor acoustic window (n=11) were excluded. Clinical, imaging, laboratory and TTE findings were compared in patients with versus without PH (estimated systolic pulmonary artery pressure >35 mm Hg) and with versus without RVD (tricuspid annular plane systolic excursion <17 mm or S wave <9.5 cm/s). The primary endpoint was in-hospital death or ICU admission. RESULTS A total of 200 patients were included in the final analysis (median age 62 (IQR 52-74) years, 65.5% men). The prevalence of PH and RVD was 12.0% (24/200) and 14.5% (29/200), respectively. Patients with PH were older and had a higher burden of pre-existing cardiac comorbidities and signs of more severe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (radiological lung involvement, laboratory findings and oxygenation status) compared with those without PH. Conversely, patients with RVD had a higher burden of pre-existing cardiac comorbidities but no evidence of more severe SARS-CoV-2 infection compared with those without RVD. The presence of PH was associated with a higher rate of in-hospital death or ICU admission (41.7 vs 8.5%, p<0.001), while the presence of RVD was not (17.2 vs 11.7%, p=0.404). CONCLUSIONS Among hospitalised non-ICU patients with COVID-19, PH (and not RVD) was associated with signs of more severe COVID-19 and with worse in-hospital clinical outcome.

Abstract
The clinical presentation of symptomatic SARS-CoV-2 not only includes viral pneumonia, but also milder illness overlapping with influenza-like illness (ILI), allowing a potential tracking of the infection in the framework of the national influenza surveillance system (SS). By comparing the data recorded by the influenza SS in 2019-20 season to those collected for the previous years, we want to evaluate whether the implementation of ILI SS could succeed in early detection and monitoring of Covid-19 diffusion. We analyzed the data recorded by the influenza SS and we compared the distribution of ILI incidence rate by week for 2017-18, 2018-19 and 2019-20 season in order to understand whether the SS detected any abnormality coinciding with Covid-19 outbreak. The distribution of ILI cases in the three seasons presented a similar pattern up to the 9th week; after then, a reduction in the ILI incidence rate was observed in the 2017-18 and the 2018-19 season while an increase was detected for 2019-20. During 2019-20 season, three major characteristics stand out: i) at the beginning of Covid-19 epidemic (7th-9th week) 9,17/1000 cases were reported; ii) during the recognition of the COVID-19 outbreak (9th-10th week) 6,36/1000 cases; iii) during the spread of Covid-19 (10th-11th week) an unexpected increase to 7,72/1000 cases. Additionally, their geographical distribution was concentrated in the areas known to be most affected by the epidemic. The influenza SS enabled us to detect the introduction and distribution of COVID-19. Implementation of the system should be prioritized in order to early identify new waves of Covid-19 but also any future novel respiratory pathogen. In order to empower the SS, it would be advisable to increase the population coverage about 2% which is the actual standard.

Abstract
Background:
Coronavirus disease 2019 (COVID-19) pandemic has led to a fast and radical transformation in social, economic, and healthcare networks. COVID-19 outbreak may thus have profound indirect consequences on clinical presentation and management of patients with ST-segment–elevation myocardial infarction (STEMI). Aim of this study was to assess clinical features of patients with STEMI during COVID-19 pandemic.
Methods:
This single-center, prospective study from a regional public service healthcare hub in Milan included all consecutive patients with STEMI admitted to our institute from February 21 to April 1, 2020 (during COVID-19 pandemic). These patients were compared with a historical cohort of patients admitted for STEMI during the analogous time period (February 21 to April 1) in 2018 and 2019, in terms of time from symptoms onset to hospital admission, clinical characteristics, and in-hospital outcomes.
Results:
A total of 26 patients were admitted for STEMI during the study period, and 7 (26.9%) of these patients tested positive for severe acute respiratory syndrome coronavirus 2. On admission, medical therapy, including angiotensin-converting enzyme inhibitors and angiotensin receptor blockers use, was similar between cohorts. Median (interquartile range) time from symptoms onset to hospital admission was significantly longer in 2020 as compared to the historical cohort (15.0 [2.0–48.0] versus 2.0 [1.0–3.0] hours;
P
<0.01). A higher proportion of patients presenting with late presentation STEMI was observed in 2020 compared with the historical cohort (50.0% versus 4.8%;
P
<0.01). Primary percutaneous coronary intervention resulted indicated in 80.8% of patients in 2020 compared with 100% in the historical cohort (
P
=0.06). In-hospital death, thromboembolism, mechanical ventilation, or hemodynamic decompensation needing inotropic or mechanical support were similar between years.
Conclusions:
These preliminary results from a cardiovascular regional public service healthcare hub demonstrate a significantly longer time from symptoms onset to hospital admission among patients with STEMI during COVID-19 pandemic compared with the same time period in the previous 2 years.

Meta-Analysis Comparing P2Y 12 Inhibitors in Acute Coronary Syndrome. Am J Cardiol 2020; 125:1815-1822. [PMID: 32305225 DOI: 10.1016/j.amjcard.2020.03.019] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Revised: 03/14/2020] [Accepted: 03/19/2020] [Indexed: 10/24/2022]
Abstract
Dual antiplatelet therapy combining aspirin with a P2Y12-receptor inhibitor reduces atherothrombotic events following an acute coronary syndromes (ACS), but the relative merits of different P2Y12 inhibitors remain unclear, despite several recent large-scale trials. We performed a network meta-analysis, representing the largest evidence to date to inform P2Y12 inhibitor choice in patients with ACS. Fourteen studies were included, for a total population of 145,019 patients. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used in this systematic review. A network meta-analysis using a frequentist approach with surface under the cumulative ranking probability calculation was performed. Major adverse cardiovascular events (MACE), all-cause death, myocardial infarction (MI), definite stent thrombosis (ST) and major bleeding at 30-day and 1-year all-cause death and MI were the study endpoints. At 30-day, prasugrel was superior to both clopidogrel and ticagrelor in MACE, all-cause death and definite ST endpoints. Both prasugrel and ticagrelor were superior to clopidogrel in MI endpoint. Ticagrelor also reduced all-cause death compared with clopidogrel. Ticagrelor, prasugrel, and clopidogrel resulted equivalent in terms of the safety outcome of 30-day major bleeding. No significant difference was found among clopidogrel, prasugrel, and ticagrelor with respect to 1-year MACE outcome. Both prasugrel and ticagrelor reduced the occurrence of 1-year all-cause death compared with clopidogrel. Prasugrel reduced 1-year MI rate as compared with clopidogrel, while ticagrelor did not. At probability analyses, prasugrel ranked best in all 30-day and 1-year efficacy and safety endpoints. In conclusion, in this network meta-analysis, prasugrel showed the highest efficacy in reducing adverse outcomes in ACS patients and had the highest probability of being the best P2Y12 inhibitor to reduce hard adverse events both at 30-day and 1-year follow-up.

Abstract
The coronavirus disease-2019 (COVID-19) pandemic has caused an enormous strain on healthcare systems and society on a global scale. We report a new phenomenon of medical care avoidance among patients with acute coronary syndrome, which is due to concerns about contracting severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection during hospital stay, ultimately leading to dire clinical outcomes.

Strategies of left ventricular unloading during VA-ECMO support: a network meta-analysis. Int J Cardiol 2020; 312:16-21. [PMID: 32057479 DOI: 10.1016/j.ijcard.2020.02.004] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Revised: 01/12/2020] [Accepted: 02/02/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Left ventricle (LV) unloading during VenoArterial ExtraCorporeal Membrane Oxygenation (VA-ECMO) reduces the risk of LV distention, stagnation and pulmonary congestion resulting from the increased afterload. Lacking direct comparisons between unloading strategies we used network meta-analysis to indirectly compare different unloading approaches. METHODS A literature research was performed to include all studies on VA-ECMO reporting data on mechanical LV unloading. The pre-specified outcome was in-hospital death. RESULTS Literature search identified 389 studies: 16 were included in the analysis (3930 patients). Two strategies of mechanical LV unloading were compared: afterload reduction (IABP) and preload reduction (Impella pump, right upper pulmonary/trans-septal catheters, LV surgical vents). Any LV unloading strategy was associated with mortality reduction with overall OR = 0.54; 95% CI 0.42-0.70; p < .001. Targeting afterload was associated with reduced mortality (OR = 0.61 95% CI 0.46-0.81; p < .001; I2 = 61%), as targeting preload (OR = 0.34 95% CI 0.21-0.55; p < .001; I2 = 0%). Significant between group difference was observed (p = .04): to further explore this we performed a network meta-analysis. Indirect comparisons between afterload and preload reduction were estimated. Any unloading technique was confirmed better than none but preload targeting resulted better than afterload targeting. CONCLUSION Any unloading strategy in VA-ECMO patients was associated with lower mortality as compared to no-unloading. Preload reduction strategies resulted superior to afterload reduction.

Long-Term Outcomes of Chronic Total Occlusion Recanalization Versus Percutaneous Coronary Intervention for Complex Non-Occlusive Coronary Artery Disease. Am J Cardiol 2020; 125:182-188.

Abstract
The durability of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) is uncertain. We aimed to compare the long-term outcomes of CTO PCI with those of complex non-CTO PCI. We built a single-center registry including all patients who underwent CTO and complex non-CTO PCI between 2012 and 2017. Complex non-CTO PCI was defined as: 3 vessels treated, ≥3 stents implanted, total stent length >60 mm, saphenous vein graft intervention, 2-stent bifurcation intervention, left main PCI, protected PCI, or rotational/laser atherectomy. The primary endpoint was target-lesion failure, a composite of cardiac death, myocardial infarction, and target-lesion revascularization. A total of 2,396 patients were included (n=609 CTO PCI, n=1,787 complex non-CTO PCI). Patients who underwent CTO PCI were younger and had higher prevalence of cardiovascular comorbidities. CTO PCI patients exhibited worse procedural metrics and success rate (74% vs 98%, p <0.001). They also suffered a higher incidence of coronary perforation (3.5% vs 2.0%, p = 0.04) and cardiac tamponade (0.8% vs 0.1%, p = 0.001). However, there was no difference in the overall incidence of in-hospital major adverse cardiac and cerebrovascular events (4.1% vs 5.0%, p = 0.40). At 36 months, there were no differences in the incidence of target-lesion failure (10.1% vs 9.9%, p = 0.91) or its individual components, between the CTO and complex non-CTO group. This finding was confirmed on multivariable analysis. In conclusion, CTO PCI is associated with lower success rates and higher risk for coronary perforation and tamponade compared with complex non-CTO PCI. The incidence of other in-hospital and long-term adverse events is similar and reasonably low.

Abstract
Abstract
Background
Ensuring access to safe and quality drinking water is an essential aspect of public health, as well as a fundamental human right as an extension of the right to life affirmed by the Universal Declaration of Human Rights. Previously in Lombardy, the reporting of water sampling control activities was prepared only by the local health authorities (LHAs). Recently, however, the activation of a data centralization information system allows the monitoring of the whole regional territory and the elaboration of a periodic report.
Methods
The data relating to the analytical checks on drinking water in the Lombardy Region were extracted from the regional database for 2014, 2015 and 2016 and grouped by ’Chemical’, ’Microbiological’ and ’Indicators’ parameters.
The analysis focused on the number and analytical compliance of all the samples performed. All the results considered both the overall regional data and each LHA.
Results
From a quantitative point of view, the activity of entering the sampling data seems to progressively improve, remaining rather heterogeneous among the various LHAs.
From a qualitative point of view drinking water in Lombardy is to be considered good overall: both the chemical and microbiological non-compliant samples in Lombardy are lower than 10% for the years 2014 and 2015 and lower than 5% in 2016 thus indicating an apparently improving trend.
Conclusions
For a better evaluation of the numerical appropriateness of the controls carried out, an update of the registry system of the supply areas and a more uniform LHA programming is necessary.
For a better assessment of the quality of water destined for human consumption oriented to the conformity of parameters, it is necessary to adopt an analytical judgment system on individual parameters instead of on the entire sample. A further improvement will be the inclusion in the database of the data of the aqueduct managers included in the Water Safety Plans (WSPs).
Key messages
Water quality assessment and its control activity reporting is an essential aspect in public health prevention. It is essential to strive for continuous improvement in the data collection method to better monitor potential risks and to evaluate the best future safe water supply strategies.

Abstract
Abstract
Background
The Impella () percutaneous mechanical circulatory support device is a catheter-based, impeller-driven, axial-flow pump. It reduces left ventricular (LV) stroke work and myocardial oxygen demand while increasing systemic and coronary perfusion in the setting of cardiogenic shock (CS).
Purpose
The aim of the study was to evaluate clinical characteristics and outcomes of patients with CS treated with Impella at our center.
Methods
Our single-center, real-world, observational registry included all consecutive patients with CS treated with Impella 2.5, CP, 5.0, or RP at our center from February 2013 to June 2018. Indication for Impella implantation was CS, defined as hypotension (systolic blood pressure <90 mmHg) despite adequate filling status with signs of hypoperfusion.
Results
A total of 130 patients were included in the registry, mean age was 61±12 years, and 79.2% were males. A history of prior MI, chronic heart failure, and chronic kidney disease was present in 28.9%, 26.1%, and 18.3%, respectively. The etiologies of CS were the following: fulminant myocarditis in 6.1% of the patients, acute coronary syndromes in 59.2%, peri-procedural CS during ventricular tachycardia ablation in 7.7% and acute heart failure in 27%. Out-of-hospital cardiac arrest was present in 30.4% of the patients; 60.2% were in INTERMACS I class at presentation. At admission, mean arterial pressure (MAP) was 65±18 mmHg, serum lactate was 6.7±5.5 mmol/L, mean left ventricular ejection fraction 21.4±11.7%, right ventricular dysfunction was indeed present in 48.6% of the patients. Inotropic drugs support was used in 66.4% of the patients. Impella 2.5, CP, and 5.0 were implanted in 76.1%, 15.4%, and 1.5% of the patients, respectively. Impella RP was also used in 11.5% of patients.The mean duration of support was 135±167 hours. Of note, extra-corporeal membrane oxygenation (ECMO) and intra-aortic balloon pump (IABP) were implanted before Impella insertion in 42.8% and 46.7% of the patients, respectively. Escalation to ECMO, ventricular assist device, or heart transplantation was needed in 35.8% of the patients. During hospital stay, acute kidney injury occurred in 56.7% of the patients; need of renal replacement therapy (RRT) 31.7%; access site-related bleeding 14.3%; life-threatening bleeding 31.5%; acute limb ischemia 14.5%; hemolysis 33.3%. The rate of all-cause mortality at 30 day was 39.7%. Need of RRT was the only independent predictor of 30-day mortality (OR 6.56; CI 1.71–25.15; p=0.006).
Conclusion
Our single-center, real-world, observational experience reports acceptable clinical outcomes after Impella implantation in a particularly complex population of patients with CS (INTERMACS class I in 60.2% of patients, prior use of ECMO in 42.8% of patients). All-cause mortality at 30 days was 39.7%, and need of RRT was the only independent predictor for 30-day mortality.

Abstract
Abstract
Background
The Impella (Abiomed, Danvers, MA) mechanical circulatory support is a catheter-based axial-flow pump. It reduces left ventricular (LV) stroke work and myocardial oxygen demand while increasing systemic and coronary perfusion in the setting of cardiogenic shock (CS), and it provides hemodynamic support during high-risk percutaneous coronary intervention (PCI).
Purpose
To evaluate the outcomes of Impella-supported patients in the context of CS and protected-PCI.
Methods
This single-center registry includes all patients implanted with Impella device at our institution between February 2013 and June 2018. Indications for Impella support were CS (hypotension despite adequate filling status with signs of hypoperfusion) and protected-PCI (prophylactic hemodynamic support during non-emergent high-risk PCI).
Results
A total of 145 patients were implanted with Impella: 130 (89.7%) for CS and 15 (10.3%) for protected-PCI. Among CS patients, mean age was 61.6±12.9, 79.2% males. The prevalence of chronic heart failure (HF) was 26.1%, prior myocardial infarction (MI) 29% and myocardial revascularization 36.6%, chronic kidney disease (CKD) 18.3%. Among protected PCI patients, mean age was 73.4±8.7 years, 86.7% males. The prevalence of HF was 85.7%, prior MI 42.9%, myocardial revascularization 35.7%, CKD 57.1%. In CS group, the indications for Impella implantation were myocarditis in 8 (6.2%) patients, acute coronary syndromes in 77 (59.2%), periprocedural ventricular tachycardia ablation CS in 10 (7.7%), decompensated heart failure in 26.9%. Out of hospital cardiac arrest occurred in 35 (30.4%) patients, INTERMACS I class in 70 (59.3%), mean arterial pressure was 65.4±18.4 mmHg, serum lactate 6.7±5.5 mmol/l, at least 1 inotropic agent use in 73 (66.4%), mean LV EF 21.4±11,7%, right ventricular dysfunction in 53 (48.6%). The rate of device-related complications was not negligible in CS group: 18 (14.5%) patients had limb ischemia and vascular surgery was required in 14, 17 (14.3%) had access-site bleeding. A total of 42 (33.3%) had haemolysis, and 67 (56.8%) acute kidney injury (AKI), half of whom requiring renal replacement therapy. Escalation to other therapies was necessary in 43 cases. Conversely, in the protected-PCI group a low rate of AKI (n=4, 28.6%) and acute limb ischemia (n=1, 7.1%) was observed, whereas no cases of haemolysis nor need of escalation therapy were recorded. Mean Impella support was 135.5±167.21 days for CS group, 60.6±80 for protected-PCI group. Survival at 30 days was 60.33% for CS group and 92.9% for protected-PCI group. One-year all-cause death was 50% for CS group and 13.3% for protected-PCI group.
Conclusion
Mechanical circulatory support with Impella is associated with good outcomes and reasonable rates of complications in the protected-PCI group, whereas less favorable results were observed in CS population probably due to the greater severity of clinical presentation.

Abstract
The COMBO stent is a new, sirolimus-eluting bioresorbable polymer, bioengineered stent. This technology combines the advantages of second-generation drug-eluting stents with the endothelial progenitor cell capture technology mediated by the anti-CD34 antibody coating on the COMBO luminal surface. This dual technology should improve vessel endothelium regeneration and may lay the biological basis for a short dual antiplatelet therapy course. As new evidence is adding on the safety and efficacy of this stent compared with first- and second-generation drug-eluting stents and across a variety of patient populations, aim of this review is to summarize available clinical experience and future perspective with this device.

Abstract
One of the most intriguing aspects of quantum mechanics is the impossibility of measuring at the same time observables corresponding to noncommuting operators, because of quantum uncertainty. This impossibility can be partially relaxed when considering joint or sequential weak value evaluation. Indeed, weak value measurements have been a real breakthrough in the quantum measurement framework that is of the utmost interest from both a fundamental and an applicative point of view. In this Letter, we show how we realized for the first time a sequential weak value evaluation of two incompatible observables using a genuine single-photon experiment. These (sometimes anomalous) sequential weak values revealed the single-operator weak values, as well as the local correlation between them.

Abstract
Weak value measurements have recently given rise to a great amount of interest in both the possibility of measurement amplification and the chance for further quantum mechanics foundations investigation. In particular, a question emerged about weak values being proof of the incompatibility between quantum mechanics and noncontextual hidden variables theories (NCHVTs). A test to provide a conclusive answer to this question was given by Pusey [Phys. Rev. Lett. 113, 200401 (2014)], where a theorem was derived showing the NCHVT incompatibility with the observation of anomalous weak values under specific conditions. In this Letter we realize this proposal, clearly pointing out the connection between weak values and the contextual nature of quantum mechanics.
