Manoel Fernandes; FURTADO, F.; GONCALVES, R.; BARRETTO, A.; OLIVEIRA JR., M.; PISANI, B.; BAPTISTA, R.; MOURA, B.- Endovascular therapeutic hypothermia adjunctive to percutaneous coronary intervention in acute myocardial infarction: realistic simulation as a game changer(2022) DALLAN, Luis Augusto Palma; DAE, Michael; GIANNETTI, Natali Schiavo; POLASTRI, Tathiane Facholi; LIMA, Marian Keiko Frossard; ROCHITTE, Carlos Eduardo; HAJJAR, Ludhmila Abrahao; MARTIN, Claudia Yanet Bernoche San; LIMA, Felipe Gallego; NICOLAU, Jose Carlos; JR, Mucio Tavares de Oliveira; DALLAN, Luis Alberto Oliveira; SILVA, Expedito Eustaquio Ribeiro da; FILHO, Roberto Kalil; ABIZAID, Alexandre; LEMOS NETO, Pedro Alves; TIMERMAN, SergioBackground: Endovascular therapeutic hypothermia (ETH) reduces the damage by ischemia/reperfusion cell syndrome in cardiac arrest and has been studied as an adjuvant therapy to percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI). New available advanced technology allows cooling much faster, but there is paucity of resources for training to avoid delays in door-to-balloon time (DTB) due to ETU and subsequently coronary reperfusion, which would derail the procedure. The aim of the study was to describe the process for the development of a simulation, training & educational protocol for the multidisciplinary team to perform optimized ETH as an adjunctive therapy for STEMI. Methods and results: We developed an optimized simulation protocol using modern mannequins in different realistic scenarios for the treatment of patients undergoing ETH adjunctive to PCI for STEN s starting from the emergency room, through the CathLab, and to the intensive care unit (ICU) using the Proteus (R) Endovascular System (loll Circulation Inc (TM), San Jose, CA, USA). The primary endpoint was door-to-balloon (DTB) time. We successfully trained 361 multidisciplinary professionals in realistic simulation using modern mannequins and sham situations in divisions of the hospital where real patients would be treated. The focus of simulation and training was logistical optimization and educational debriefing with strategies to reduce waste of time in patient's transportation from different departments, and avoiding excessive rewanning during transfer. Afterwards, the EHT protocol was successfully validated in a trial randomizing 50 patients for 18 minutes cooling before coronary recanalization at the target temperature of 32 +/- 1.0 degrees C or PCI-only. A total of 35 patients underwent FM (85.7% [30/35] in 90 +/- 15 minutes), without delays in the mean door-to-balloon time for primary PCI when compared to 15 control group patients (92.1 minutes versus 87 minutes, respectively; p = 0.509). Conclusions: Realistic simulation, intensive training and educational debriefing for the multidisciplinary team propitiated feasible endovascular therapeutic hypothermia as an adjuvant therapy to primary PCI in STEM.

Non-invasive ventilation (NIV), the application of positive intrathoracic pressure through an interface, has shown to be useful in the treatment of moderate to severe RF in several scenarios. There are two main modalities of NIV: continuous positive airway pressure (CPAP) and pressure support ventilation (NIPSV) with positive end expiratory pressure. Appropriate equipment and experience is needed for NIPSV, whereas CPAP may be administered without a ventilator, not requiring special training. Both modalities have shown to be effective in ACPE, by a reduction of respiratory distress and the endotracheal intubation rate compared to conventional oxygen therapy, but the impact on mortality is less conclusive. Non-invasive ventilation is also indicated in patients with AHF associated to pulmonary disease and may be considered, after haemodynamic stabilization, in some patients with CS. There are no differences in the outcomes in the studies comparing both techniques, but CPAP is a simpler technique that may be preferred in low-equipped areas like the pre-hospital setting, while NIPSV may be preferable in patients with significant hypercapnia. The new modality 'high-flow nasal cannula' seems promising in cases of AHF with less severe RF. The correct selection of patients and interfaces, early application of the technique, the achievement of a good synchrony between patients and the ventilator avoiding excessive leakage, close monitoring, proactive management, and in some cases mild sedation, may warrant the success of the technique.
- Diagnostic Ultrasound Impulses Improve Microvascular Flow in Patients With STEMI Receiving Intravenous Microbubbles(2016) MATHIAS JR., Wilson; TSUTSUI, Jeane M.; TAVARES, Bruno G.; XIE, Feng; AGUIAR, Miguel O. D.; GARCIA, Diego R.; OLIVEIRA JR., Mucio T.; SOEIRO, Alexandre; NICOLAU, Jose C.; LEMOS NETO, Pedro A.; ROCHITTE, Carlos E.; RAMIRES, Jose A. F.; KALIL FILHO, Roberto; PORTER, Thomas R.BACKGROUND Pre-clinical trials have demonstrated that, during intravenous microbubble infusion, high mechanical index (HMI) impulses from a diagnostic ultrasound (DUS) transducer might restore epicardial and microvascular flow in acute ST-segment elevation myocardial infarction (STEMI). OBJECTIVES The purpose of this study was to test the safety and efficacy of this adjunctive approach in humans. METHODS From May 2014 through September 2015, patients arriving with their first STEMI were randomized to either DUS intermittent HMI impulses (n = 20) just prior to emergent percutaneous coronary intervention (PCI) and for an additional 30 min post-PCI (HMI + PCI), or low mechanical index (LMI) imaging only (n = 10) for perfusion assessments before and after PCI (LMI + PCI). All studies were conducted during an intravenous perflutren lipid microsphere infusion. A control reference group (n = 70) arrived outside of the time window of ultrasound availability and received emergent PCI alone (PCI only). Initial epicardial recanalization rates prior to emergent PCI and improvements in microvascular flow were compared between ultrasound-treated groups. RESULTS Median door-to-dilation times were 82 +/- 26 min in the LMI + PCI group, 72 +/- 15 min in the HMI + PCI group, and 103 +/- 42 min in the PCI-only group (p = NS). Angiographic recanalization prior to PCI was seen in 12 of 20 HMI + PCI patients (60%) compared with 10% of LMI + PCI and 23% of PCI-only patients (p = 0.002). There were no differences in microvascular obstructed segments prior to treatment, but there were significantly smaller proportions of obstructed segments in the HMI + PCI group at 1 month (p = 0.001) and significant improvements in left ventricular ejection fraction (p < 0.005). CONCLUSIONS HMI impulses from a diagnostic transducer, combined with a commercial microbubble infusion, can prevent microvascular obstruction and improve functional outcome when added to the contemporary PCI management of acute STEMI.

- Expert consensus document: Reporting checklist for quantification of pulmonary congestion by lung ultrasound in heart failure(2019) PLATZ, Elke; JHUND, Pardeep S.; GIRERD, Nicolas; PIVETTA, Emanuele; MCMURRAY, John J. V.; PEACOCK, W. Frank; MASIP, Josep; MARTIN-SANCHEZ, Francisco Javier; MIRO, Oscar; PRICE, Susanna; CULLEN, Louise; MAISEL, Alan S.; VRINTS, Christiaan; COWIE, Martin R.; DISOMMA, Salvatore; BUENO, Hector; MEBAZAA, Alexandre; GUALANDRO, Danielle M.; TAVARES, Mucio; METRA, Marco; COATS, Andrew J. S.; RUSCHITZKA, Frank; SEFEROVIC, Petar M.; MUELLER, ChristianLung ultrasound is a useful tool for the assessment of patients with both acute and chronic heart failure, but the use of different image acquisition methods, inconsistent reporting of the technique employed and variable quantification of 'B-lines,' have all made it difficult to compare published reports. We therefore need to ensure that future studies utilizing lung ultrasound in the assessment of heart failure adopt a standardized approach to reporting the quantification of pulmonary congestion. Strategies to improve patient care by use of lung ultrasound in the assessment of heart failure have been difficult to develop. In the present document, key aspects of standardization are discussed, including equipment used, number of chest zones assessed, the method of quantifying B-lines, the presence and timing of additional investigations (e.g. natriuretic peptides and echocardiography) and the impact of therapy. This consensus report includes a checklist to provide standardization in the preparation, review and analysis of manuscripts. This will serve as a guide for investigators and clinicians and enhance the quality and transparency of lung ultrasound research.
- Risk stratification scores for patients with acute heart failure in the Emergency Department: A systematic review(2020) MIRO, Oscar; ROSSELLO, Xavier; PLATZ, Elke; MASIP, Josep; GUALANDRO, Danielle M.; PEACOCK, W. Frank; PRICE, Susanna; CULLEN, Louise; DISOMMA, Salvatore; JR, Mucio Tavares de Oliveira; V, John J. McMurray; MARTIN-SANCHEZ, Francisco J.; MAISEL, Alan S.; VRINTS, Christiaan; COWIE, Martin R.; BUENO, Hector; MEBAZAA, Alexandre; MUELLER, ChristianAims: This study aimed to systematically identify and summarise all risk scores evaluated in the emergency department setting to stratify acute heart failure patients. Methods and results: A systematic review of PubMed and Web of Science was conducted including all multicentre studies reporting the use of risk predictive models in emergency department acute heart failure patients. Exclusion criteria were: (a) non-original articles; (b) prognostic models without predictive purposes; and (c) risk models without consecutive patient inclusion or exclusively tested in patients admitted to a hospital ward. We identified 28 studies reporting findings on 19 scores: 13 were originally derived in the emergency department (eight exclusively using acute heart failure patients), and six in emergency department and hospitalised patients. The outcome most frequently predicted was 30-day mortality. The performance of the scores tended to be higher for outcomes occurring closer to the index acute heart failure event. The eight scores developed using acute heart failure patients only in the emergency department contained between 4-13 predictors (age, oxygen saturation and creatinine/urea included in six scores). Five scores (Emergency Heart Failure Mortality Risk Grade, Emergency Heart Failure Mortality Risk Grade 30 Day mortality ST depression, Epidemiology of Acute Heart Failure in Emergency department 3 Day, Acute Heart Failure Risk Score, and Multiple Estimation of risk based on Emergency department Spanish Score In patients with Acute Heart Failure) have been externally validated in the same country, and two (Emergency Heart Failure Mortality Risk Grade and Multiple Estimation of risk based on Emergency department Spanish Score In patients with Acute Heart Failure) further internationally validated. The c-statistic for Emergency Heart Failure Mortality Risk Grade to predict seven-day mortality was between 0.74-0.81 and for Multiple Estimation of risk based on Emergency department Spanish Score In patients with Acute Heart Failure to predict 30-day mortality was 0.80-0.84. Conclusions: There are several scales for risk stratification of emergency department acute heart failure patients. Two of them are accurate, have been adequately validated and may be useful in clinical decision-making in the emergency department i.e. about whether to admit or discharge.
- OSA and Prognosis After Acute Cardiogenic Pulmonary Edema The OSA-CARE Study(2017) UCHOA, Carlos Henrique G.; PEDROSA, Rodrigo P.; JAVAHERI, Shahrokh; GEOVANINI, Glaucylara R.; CARVALHO, Martinha M. B.; TORQUATRO, Ana Claudia S.; LEITE, Ana Paula D. L.; GONZAGA, Carolina C.; BERTOLAMI, Adriana; AMODEO, Celso; PETISCO, Ana Claudia G. P.; BARBOSA, Jose Eduardo M.; MACEDO, Thiago A.; BORTOLOTTO, Luiz A.; OLIVEIRA JR., Mucio Tavares; LORENZI-FILHO, Geraldo; DRAGER, Luciano F.BACKGROUND: Acute cardiogenic pulmonary edema (ACPE) is a life-threatening condition. OSA may be a modifiable risk factor for ACPE recurrence. This study was designed to evaluate the impact of OSA on the incidence of cardiovascular events following ACPE recovery. METHODS: Consecutive patients with confirmed ACPE from 3 centers underwent a sleep study following clinical stabilization. OSA was defined as an apnea-hypopnea index (AHI) >= 15 events/h. The mean follow-up was 1 year, and the primary outcome was ACPE recurrence. RESULTS: A total of 104 patients were included in the final analysis; 61% of the patients had OSA. A higher rate of ACPE recurrence (25 vs 6 episodes; P = .01) and a higher incidence of myocardial infarction (15 vs 0 episodes; P = .0004) were observed in patients with OSA than in those without OSA. All 17 deaths occurred in the OSA group (P = .0001). In a Cox proportional hazards regression analysis, OSA was independently associated with ACPE recurrence (hazard ratio [HR], 3.3 [95% CI, 1.2-8.8]; P = .01), incidence of myocardial infarction (HR, 2.3 [95% CI, 1.1-9.5]; P = .02), cardiovascular death (HR, 5.4 [95% CI, 1.4-48.4]; P = .004), and total death (HR, 6.5 [95% CI, 1.2-64.0]; P = .005). When the analysis was limited only to patients with OSA, levels of AHI and hypoxemic burden and rates of sleep-onset ACPE were significantly higher in those who presented with ACPE recurrence or who died than in those who did not experience these events. CONCLUSIONS: OSA is independently associated with higher rates of ACPE recurrence and both fatal and nonfatal cardiovascular events.
