RESUMEN
OBJECTIVES: We aim to assess the early use of contrast-enhanced computed tomography (CECT) of patients with severe acute pancreatitis (SAP) using the computed tomography severity index (CTSI) in prognosis prediction. The CTSI combines quantification of pancreatic and extrapancreatic inflammation with the extent of pancreatic necrosis. METHODS: Post-hoc retrospective analysis of a large, multicentric database (44 institutions) of SAP patients in Japan. The area under the curve (AUC) of the CTSI for predicting mortality and the odds ratio (OR) of the extent of pancreatic inflammation and necrosis were calculated using multivariable analysis. RESULTS: In total, 1097 patients were included. The AUC of the CTSI for mortality was 0.65 (95 % confidence interval [CI:] [0.59-0.70]; p < 0.001). In multivariable analysis, necrosis 30-50 % and >50 % in low-enhanced pancreatic parenchyma (LEPP) was independently associated with a significant increase in mortality, with OR 2.04 and 95 % CI 1.01-4.12 (P < 0.05) and OR 3.88 and 95 % CI 2.04-7.40 (P < 0.001), respectively. However, the extent of pancreatic inflammation was not associated with mortality, regardless of severity. CONCLUSIONS: The degree of necrosis in LEPP assessed using early CECT of SAP was a better predictor of mortality than the extent of pancreatic inflammation.
RESUMEN
BACKGROUND: The prevalence of extracorporeal cardiopulmonary resuscitation (ECPR) in patients with out-of-hospital cardiac arrest (OHCA) has been increasing rapidly worldwide. However, guidelines or clinical studies do not provide sufficient data on ECPR practice. The aim of this study was to provide real-world data on ECPR for patients with OHCA, including details of complications. METHODS: We did a retrospective database analysis of observational multicenter cohort study in Japan. Adult patients with OHCA of presumed cardiac etiology who received ECPR between 2013 and 2018 were included. The primary outcome was favorable neurological outcome at hospital discharge, defined as a cerebral performance category of 1 or 2. RESULTS: A total of 1644 patients with OHCA were included in this study. The patient age was 18-93 years (median: 60 years). Shockable rhythm in the initial cardiac rhythm at the scene was 69.4%. The median estimated low flow time was 55 min (interquartile range: 45-66 min). Favorable neurological outcome at hospital discharge was observed in 14.1% of patients, and the rate of survival to hospital discharge was 27.2%. The proportions of favorable neurological outcome at hospital discharge in terms of shockable rhythm, pulseless electrical activity, and asystole were 16.7%, 9.2%, and 3.9%, respectively. Complications were observed during ECPR in 32.7% of patients, and the most common complication was bleeding, with the rates of cannulation site bleeding and other types of hemorrhage at 16.4% and 8.5%, respectively. CONCLUSIONS: In this large cohort, data on the ECPR of 1644 patients with OHCA show that the proportion of favorable neurological outcomes at hospital discharge was 14.1%, survival rate at hospital discharge was 27.2%, and complications were observed during ECPR in 32.7%.

BACKGROUND: Data on extracorporeal cardiopulmonary resuscitation (ECPR) in patients with out-of-hospital cardiac arrest (OHCA) and initially nonshockable rhythms are limited. OBJECTIVE: This study aimed to evaluate the long-term neurological outcomes of ECPR for patients with OHCA and initially nonshockable rhythms. METHODS: In this single-center, consecutive, retrospective, observational study, patients with OHCA and initially nonshockable rhythms who underwent ECPR between January 2012 and December 2017 were included. All patients with refractory cardiopulmonary arrest were transported while undergoing conventional CPR and received ECPR on arrival in the emergency department. We retrospectively collected characteristics at admission and neurological outcomes at the last visit or telephone interview. Cerebral performance category (CPC) scales 1 and 2 were defined as good neurological outcomes and CPC scales 3, 4, and 5 were defined as poor neurological outcomes. RESULTS: Of the 39 patients included in this study, 32 died in the hospital and only 7 survived. There were 4, 0, 0, 3, and 32 patients with CPC 1, 2, 3, 4, and 5, respectively. The proportion of good neurological outcomes for all patients was 10.3% (95% CI 2.9-24.2%) and 14.3% (95% CI 4.0-32.7%) for patients with pulseless electrical activity. No patients with asystole had a good neurological outcome. Median follow-up period was 1052 days (interquartile range 116-1589 days) for those who survived to discharge. CONCLUSIONS: Approximately 10% of initially nonshockable patients with OHCA, generally considered to be a poor prognosis, could acquire good neurological outcomes when they underwent ECPR with our indications.

BACKGROUND: The effect of in-hospital rapid cooling by intravenous ice-cold fluids for comatose survivors of out-of-hospital cardiac arrest (OHCA) is unclear.MethodsâandâResults:From the J-PULSE-HYPO study registry, data for 248 comatose survivors with return of spontaneous circulation (ROSC) who were treated with therapeutic hypothermia (34â for 12-72 h) after witnessed shockable OHCA were extracted. Patients were divided into 2 groups by the median collapse-to-ROSC interval (18 min), and then into 2 groups by cooling method (rapid cooling by intravenous ice-cold fluids vs. standard cooling). The primary endpoint was favorable neurological outcome (Cerebral Performance Category of 1 or 2) at 30 days after OHCA. In the whole cohort, the shorter collapse-to-ROSC interval group had significantly higher favorable neurological outcome than the longer collapse-to-ROSC interval group (78.2% vs. 46.8%, P<0.001). In the shorter collapse-to-ROSC interval group, no significant difference was observed in favorable neurological outcome between the 2 cooling groups (rapid cooling group: 79.4% vs. standard cooling group: 77.0%, P=0.75). In the longer collapse-to-ROSC interval group, however, favorable neurological outcome was significant higher in the rapid cooling group than in the standard cooling group (60.7% vs. 33.3%, P<0.01) and the adjusted odds ratio after rapid cooling was 3.069 (95% confidence interval 1.423-6.616, P=0.004). CONCLUSIONS: In-hospital rapid cooling by intravenous ice-cold fluids improved neurologically intact survival in comatose survivors whose collapse-to-ROSC interval was delayed over 18 min after shockable OHCA.

BACKGROUND/OBJECTIVES: Severe acute pancreatitis (SAP) has a high mortality rate despite ongoing attempts to improve prognosis through a various therapeutic modalities. This study aimed to delineate etiology-based routes that may guide clinical decisions for the treatment of SAP. METHODS: Using data from a recent retrospective multicenter study in Japan, we analyzed the association between clinical outcomes, mainly in-hospital mortality and pancreatic infection, and various etiologies while considering confounding factors. We performed additional multivariate analyses and built decision tree models. RESULTS: The 1097 participating patients were classified into the following groups by etiology: alcohol (n = 436, 39.7%); cholelithiasis (n = 230, 21.0%); idiopathic (n = 227, 20.7%); and others (n = 204, 18.6%). Mortality at hospital discharge was 8.4%, 12.2%, 16.7%, and 16.2% in the alcohol, cholelithiasis, idiopathic, and others groups, respectively. According to multivariable analysis, early enteral nutrition (EN) was significantly associated with reduced in-hospital mortality only in the cholelithiasis group. However, there was a consistent association between age and the need for mechanical ventilation and increased mortality, regardless of etiology. Our decision tree models presented different contributing factors depending on the etiology and patient background. Interaction analysis showed that EN and the use of prophylactic antibiotics may influence these results differently according to etiology. CONCLUSIONS: No study has yet used comprehensive models to investigate etiology-related prognostic factors for SAP; our results can, therefore, be used as a reference for improving clinical decisions.

BACKGROUND AND AIMS: Although fluid resuscitation is critical in acute pancreatitis, the optimal fluid volume is unknown. The aim of this study is to evaluate the association between the volume of fluid administered and clinical outcomes in patients with severe acute pancreatitis (SAP). METHODS: We conducted a multicenter retrospective study at 44 institutions in Japan. Inclusion criteria were age 18 years or older, and diagnosed with SAP from 2009 to 2013. Patients were stratified into 2 groups: administered fluid volume <6000 and ≥6000 mL in the first 24 hours. We evaluated the association between the 2 groups and clinical outcomes using multivariable logistic regression analysis. The primary outcome was in-hospital mortality. Secondary outcomes included the incidence of pancreatic infection and the need for surgical intervention. RESULTS: We analyzed 1097 patients, and the mean fluid volume administered was 5618±3018 mL (mean±SD), with 708 and 389 patients stratified into the fluid <6000 mL and fluid ≥6000 mL groups, respectively. Overall in-hospital mortality was 12.3%. The fluid ≥6000 mL group had significantly higher mortality than the fluid <6000 mL group (univariable analysis, 15.9% vs. 10.3%; P<0.05). In multivariable logistic regression analysis, administration of ≥6000 mL of fluid within the first 24 hours was significantly associated with reduced mortality (odds ratio, 0.58; P<0.05). No significant association was found between the administered fluid volume and pancreatic infection, or between the volume administered and the need for surgical intervention. CONCLUSIONS: In patients with SAP, administration of a large fluid volume within the first 24 hours is associated with decreased mortality.

OBJECTIVES: Bradycardia during therapeutic hypothermia has been reported to be a predictor of favorable neurologic outcomes in out-of-hospital cardiac arrests. However, bradycardia occurrence rate may be influenced by the target body temperature. During therapeutic hypothermia, as part of the normal physiologic response, heart rate decreases in the cooling phase and increases during the rewarming phase. We hypothesized that increased heart rate during the rewarming phase is another predictor of favorable neurologic outcomes. To address this hypothesis, the study aimed to examine the association between heart rate response during the rewarming phase and neurologic outcomes in patients having return of spontaneous circulation after out-of-hospital cardiac arrest. DESIGN: A secondary analysis of the Japanese Population-based Utstein style study with defibrillation and basic/advanced Life Support Education and implementation-Hypothermia registry, which was a multicenter prospective cohort study. SETTING: Fourteen hospitals throughout Japan. PATIENTS: Patients suffering from out-of-hospital cardiac arrest who received therapeutic hypothermia after the return of spontaneous circulation from 2005 to 2011. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: This study enrolled 452 out-of-hospital cardiac arrest patients, of which 354 were analyzed, and 80.2% survived to hospital discharge, of which 57.3% had a good neurologic outcome. Heart rate response was calculated using heart rate data recorded during therapeutic hypothermia in the abovementioned registry. Heart rate response in the rewarming phase (heart rate response-rewarming) was calculated as follows: (heart rate [post rewarming]-heart rate [pre rewarming])/heart rate (pre rewarming) × 100. The primary outcome was an unfavorable neurologic outcome at hospital discharge, that is, a Cerebral Performance Category of 3-5. Multivariable logistic regression analysis was performed to determine the association between heart rate response-rewarming and unfavorable neurologic outcomes. Multivariable logistic regression analysis showed that heart rate response-rewarming was independently associated with unfavorable outcomes (odds ratio [per 10% change], 0.86; 95% CI, 0.78-0.96; p = 0.004). CONCLUSIONS: Increased heart rate in the approximately 48-hour rewarming phase during therapeutic hypothermia was significantly associated with and was an independent predictor of favorable neurologic outcomes during out-of-hospital cardiac arrest.

PURPOSE: In out-of-hospital cardiac arrest (OHCA) patients resuscitated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO), known as extracorporeal cardiopulmonary resuscitation (ECPR), bleeding is a common complication. The purpose of this study was to assess the risk factors for bleeding complications in ECPR patients. METHODS: We retrospectively analyzed the data for OHCA patients admitted to our hospital and resuscitated with ECPR between October 2009 and December 2016. We compared patients with and without major bleeding (i.e. the Bleeding Academic Research Consortium class≥3 bleeding) within 24h of hospital admission. Patients, whose bleeding complication was not evaluated, were excluded. RESULTS: During the study period, 133 OHCA patients were resuscitated with ECPR, of whom 102 (77%) were included. In total, 71 (70%) patients experienced major bleeding. There were significant differences in age (median 65 vs. 50years, P<0.001), prior antiplatelet therapy (25% vs. 3%, P=0.008), hemoglobin (median 11.6 vs. 12.6g/dL, P=0.003), platelet count (median 125 vs. 155×103/µL, P=0.001), and D-dimer levels on admission (median 18.8 vs. 6.7µg/mL, P<0.001) among patients with and those without major bleeding. Multivariate analysis showed significant associations between major bleeding and D-dimer levels (odds ratio, 1.066; 95% confidence interval, 1.018-1.116). Area under receiver-operating characteristic curve, which describes the accuracy of D-dimer levels in predicting major bleeding, was 0.76 (95% confidence interval, 0.66-0.87). CONCLUSION: D-dimer levels may predict major bleeding in ECPR patients, suggesting that hyperfibrinolysis may be related to bleeding.

PURPOSE: The aim of this study was to assess the usefulness of the Global Registry of Acute Coronary Events (GRACE) risk score in predicting in-hospital mortality and neurological outcome of patients resuscitated after out-of-hospital cardiac arrest (OHCA). METHODS: We retrospectively analyzed the data of patients admitted to our hospital between October 2009 and October 2015 with OHCA and shockable initial cardiac rhythm who were resuscitated via conventional cardiopulmonary resuscitation. We calculated the GRACE risk score on admission and assessed its usefulness in predicting in-hospital mortality and neurological outcome. RESULTS: Among 91 patients, 42 (46%) had acute myocardial infarction (AMI), 19 (21%) died in-hospital, and 52 (57%) had favorable neurological outcome. Among all the study patients, GRACE risk score was lower in survivors than in non-survivors (median 211 [interquartile range 176-240] vs. 266 [219-301], p<0.001, respectively) and in favorable than in unfavorable neurological outcome group (202 [167-237] vs. 242 [219-275], p<0.001, respectively). Multivariate analysis showed significant association between GRACE risk score and favorable neurological outcome (odds ratio, 0.975; 95% confidence interval, 0.961-0.990). Areas under receiver-operating characteristic curves, that describe the accuracy of GRACE risk score in predicting in-hospital mortality and favorable neurological outcome, were both 0.79. CONCLUSION: GRACE risk score may predict the in-hospital mortality and neurological outcome associated with resuscitated patients with OHCA and shockable initial cardiac rhythm, regardless of the cause of arrest.

BACKGROUND: Because the initial (on admission) Glasgow Coma Scale (GCS) examination has not been fully evaluated in comatose survivors of cardiac arrest (CA) who receive therapeutic hypothermia (TH), the aim of the present study was to determine any association between the admission GCS motor score and neurologic outcomes in patients with out-of-hospital CA who receive TH. METHODSâANDâRESULTS: In the J-PULSE-HYPO study registry, patients with bystander-witnessed CA were eligible for inclusion. Patients were divided into 3 groups based on GCS motor score (1, 2-3, and 4-5) to assess various effects on neurologic outcome. Univariate and multivariate analyses were performed to identify independent predictors of good neurologic outcome at 90 days. Of 452 patients, 302 were enrolled. There was a significant difference among the 3 patient groups with regard to neurologic outcome at 90 days in the univariate analysis. Multiple logistic regression analyses showed that the GCS motor score on admission, age >65 years, bystander cardiopulmonary resuscitation, the time from collapse to return of spontaneous circulation, and pupil size <4 mm were independent predictors of a good neurologic outcome at 90 days in cases of CA (GCS motor score, 4-5: odds ratio, 8.18; 95% confidence interval: 1.90-60.28; P<0.01). CONCLUSIONS: GCS motor score is an independent predictor of good neurologic outcome at 90 days in patients sustaining out-of-hospital CA who receive TH.

PURPOSE: In patients undergoing primary percutaneous coronary intervention (PCI) for the treatment of ST-segment elevation myocardial infarction (STEMI), coronary microvascular dysfunction is associated with poor prognosis. Coronary microvascular resistance is predominantly regulated by ATP-sensitive potassium (KATP) channels. The aim of this study was to clarify whether nicorandil, a hybrid KATP channel opener and nitric oxide donor, may be a good candidate for improving microvascular dysfunction even when administered after primary PCI. METHODS: We compared the beneficial effects of nicorandil and nitroglycerin on microvascular function in 60 consecutive patients with STEMI. After primary PCI, all patients received single intracoronary administrations of nitroglycerin (250 µg) and nicorandil (2 mg) in a randomized order; 30 received nicorandil first, while the other 30 received nitroglycerin first. Microvascular dysfunction was evaluated with the index of microcirculatory resistance (IMR), defined as the distal coronary pressure multiplied by the hyperemic mean transit time. RESULTS: As a first administration, nicorandil decreased IMR significantly more than did nitroglycerin (median [interquartile ranges]: 10.8[5.2-20.7] U vs. 2.1[1.0-6.0] U, p=0.0002).As a second administration, nicorandil further decreased IMR, while nitroglycerin did not (median [interquartile ranges]: 6.0[1.3-12.7] U vs. -1.4[-2.6 to 1.3] U, p<0.0001). The IMR after the second administration was significantly associated with myocardial blush grade, angiographic TIMI frame count after the procedure, and peak creatine kinase level. CONCLUSION: Intracoronary nicorandil reduced microvascular dysfunction after primary PCI more effectively than did nitroglycerin in patients with STEMI, probably via its KATP channel-opening effect.

BACKGROUND: Although therapeutic hypothermia is an effective therapy for comatose adults experiencing out-of-hospital shockable cardiac arrest, there is insufficient evidence that is also applicable for those with out-of-hospital non-shockable cardiac arrest. METHODS AND RESULTS: Of 452 comatose adults treated with therapeutic hypothermia after return of spontaneous circulation (ROSC) subsequent to an out-of-hospital cardiac arrest of cardiac etiology, 372 who had a bystander-witnessed cardiac arrest, target core temperature of 32-34°C and cooling duration of 12-72 h were eligible for this study (75 cases of non-shockable cardiac arrest, 297 cases of shockable cardiac arrest). The median collapse-to-ROSC interval was significantly longer in the non-shockable group than in the shockable group (30 min vs. 22 min, P=0.008), resulting in a significantly lower frequency of 30-day favorable neurological outcome in the non-shockable group compared with the shockable group (32% vs. 66%, P<0.001). However, an analysis of data in quartiles assigned to varying lengths of collapse-to-ROSC interval revealed a similar frequency of 30-day favorable neurological outcome among both groups when the collapse-to-ROSC interval was ≤16 min (90% non-shockable group vs. 92% shockable group; odds ratio 0.80, 95% confidence interval 0.09-7.24, P=0.84). CONCLUSIONS: Post-ROSC cooling is an effective treatment for patients with non-shockable cardiac arrest when the time interval from collapse to ROSC is short.

AIMS: T-cadherin (T-cad) is a specific binding partner of adiponectin (APN), adipocyte-specific secretory protein. APN exhibits organ protection via the T-cad-dependent accumulation onto several tissues such as the aorta, heart, and muscle. Recently, for the first time, we showed that three forms (130, 100, and 30 kDa) of soluble T-cad existed in human serum and correlated with several clinical parameters in patients with type 2 diabetes. Nevertheless, the significance of soluble T-cad has not been elucidated in the acute stage of cardiovascular diseases. We herein examined soluble T-cad concentrations and investigated their clinical significance in patients with emergency hospital admission due to ST-segment elevation myocardial infarction (STEMI). METHODS: This observational study enrolled 47 patients with STEMI who were treated via primary percutaneous coronary intervention (PCI). Soluble T-cad and APN concentrations were measured by using an enzyme-linked immunosorbent assay. This study is registered with the University Hospital Medical Information Network (Number: UMIN 000014418). RESULTS: Serum concentrations of soluble 130 and 100 kDa T-cad rapidly and significantly decreased after hospitalization and reached the bottom at 72 h after admission (pï¼0.001 and pï¼0.001, respectively). The patients with high soluble T-cad and low APN concentrations on admission showed a significantly higher area under the curve of serum creatine kinase-MB (pï¼0.01). CONCLUSION: Serum soluble T-cad concentration changed dramatically in patients with STEMI, and the high T-cad and low APN concentrations on admission were associated with the myocardial infarction size. Further study is needed to investigate the usefulness of categorizing patients with STEMI by serum T-cad and APN for the prediction of severe prognoses.

Myocardial injury has been reported as a complication of COVID-19. Although several mechanisms have been proposed as its cause, they are mostly based on autopsy studies, We report a 49-year-old male with COVID-19-associated myocardial injury presented like fulminant myocarditis. We performed endomyocardial biopsy on day 2 and we confirmed the presence of microthrombosis histologically. He died on day 5 due to cardiogenic shock.

BACKGROUND: The objective of this study was to investigate whether a distal protection (DP) device can preserve the index of microcirculatory resistance (IMR) after primary percutaneous coronary intervention (PCI) in patients with anterior ST-segment elevation myocardial infarction (STEMI). METHODS AND RESULTS: The study group of 36 consecutive patients with anterior STEMI were randomized into 2 groups of primary PCI with or without DP: stenting without DP (non-DP group, n = 17) and with DP (DP group, n = 19). The DP in all cases was Filtrap (Nipro, Japan). Following final coronary angiography after successful PCI, IMR was measured using PressureWire™ Certus (St Jude Medical, USA) at maximal hyperemia. The averaged IMR of the 36 patients with STEMI after primary PCI was 31.6U. The IMR in the DP group was significantly lower than that in the non-DP group (26.6 ± 25.8U vs. 37.2 ± 23.2U, P = 0.03242). CONCLUSIONS: DP as an adjunctive therapy of PCI for acute anterior STEMI may have beneficial effects on myocardial microcirculation because of preservation of IMR.

BACKGROUND: Mild hypothermia is an effective therapy for patients with return of spontaneous circulation (ROSC) after out-of-hospital cardiac arrest. However, evidence of the effectiveness of therapeutic hypothermia (TH) remains unclear. METHODS AND RESULTS: A multicenter registry in Japan (J-PULSE-HYPO study registry) was conducted to investigate the effectiveness of TH for post-resuscitation neurological dysfunction developing after out-of-hospital cardiac arrest from 14 institutions, between January 2005 and December 2009. The committee entrusted each hospital with the timing of cooling, cooling methods, target temperature, duration, and rewarming. There were 452 patients (375 men) enrolled into the registry. The mean age was 58.6 ± 13.5 years. Initial electrocardiogram rhythm at the time of occurrence of the cardiac arrest showed 68.9% had ventricular fibrillation or pulseless ventricular tachycardia, 13.7% had pulseless electrical activity, and 9.1% had asystole. The median interval from the occurrence of cardiac arrest to ROSC was 26 min. The target core temperature during TH was 33.9 ± 0.4°C and the mean duration of cooling was 31.5 ± 13.9 h. Intra-aortic balloon pumping was used in 40.1% and percutaneous cardiopulmonary support in 22.6% of patients. At 30 days after cardiac arrest, the proportion of survival was 80.1% and the proportion of patients with favorable neurological functions, with a cerebral performance category score of 1 or 2, was 55.3%. CONCLUSIONS: The J-PULSE-HYPO study registry showed a clinical aspect of TH.

OBJECTIVES: In patients with severe acute pancreatitis (SAP), early enteral nutrition (EN) is recommended by major clinical practice guidelines, but the exact timing for the initiation of EN is unknown. METHODS: We conducted a post hoc analysis of the database for a multicenter (44 institutions) retrospective study of patients with SAP in Japan. The patients were classified into 3 groups according to the timing of EN initiation after the diagnosis of SAP: within 24 hours, between 24 and 48 hours, and more than 48 hours. The primary outcome was in-hospital mortality. RESULTS: Of the 1094 study patients, 176, 120, and 798 patients started EN within 24 hours, between 24 and 48 hours, and more than 48 hours after SAP diagnosis, respectively. On multivariable analysis, hospital mortality was significantly better with EN within 48 hours than with more than 48 hours (adjusted odds ratio, 0.49; 95% confidence interval, 0.29-0.83; P < 0.001) but did not significantly differ between the groups with EN starting within 24 hours and between 24 and 48 hours (P = 0.29). CONCLUSIONS: Enteral nutrition within 24 hours may not confer any additional benefit on clinical outcomes compared with EN between 24 and 48 hours.

AIM: A lack of known guidelines for the provision of extracorporeal cardiopulmonary resuscitation (ECPR) to patients with out-of-hospital cardiac arrest (OHCA) has led to variability in practice between hospitals even in the same country. Because variability in ECPR practice has not been completely examined, we aimed to describe the variability in ECPR practice in patients with OHCA from the emergency department (ED) to the intensive care units (ICU). METHODS: An anonymous online questionnaire to examine variability in ECPR practice was completed in January 2020 by 36 medical institutions who participated in the SAVE-J II study. Institutional demographics, inclusion and exclusion criteria, initial resuscitation management, extracorporeal membrane oxygenation (ECMO) initiation, initial ECMO management, intra-aortic balloon pumping/endotracheal intubation/management during coronary angiography, and computed tomography criteria were recorded. RESULTS: We received responses from all 36 institutions. Four institutions (11.1%) had a hybrid emergency room. Cardiovascular surgery was always involved throughout the entire ECMO process in only 14.7% of institutions; 60% of institutions had formal inclusion criteria and 50% had formal exclusion criteria. In two-thirds of institutions, emergency physicians carried out cannulation. Catheterization room was the leading location of cannulation (48.6%) followed by ED (31.4%). The presence of formal exclusion criteria significantly increased with increasing ECPR volume (P for trend <0.001). Intra-aortic balloon pumping was routinely initiated in only 25% of institutions. Computed tomography was routinely carried out before coronary angiography in 25% of institutions. CONCLUSIONS: We described the variability in ECPR practice in patients with OHCA from the ED to the ICU.
RESUMEN
BACKGROUND: Nifekalant hydrochloride (NIF) is an intravenous class-III antiarrhythmic agent that purely blocks the K(+)-channel without inhibiting ß-adrenergic receptors. The present study was designed to investigate the feasibility of NIF as a life-saving therapy for out-of-hospital ventricular fibrillation (VF). METHODS AND RESULTS: The Japanese Population-based Utstein-style study with basic and advanced Life Support Education study was a multi-center registry study with 4 participating institutes located at the northern urban area of Osaka, Japan. Eligible patients were those treated with NIF because of out-of-hospital VF refractory to 3 or more precordial shocks and intravenous epinephrine. Between February 2006 and February 2007, 17 patients were enrolled for the study. The time from a call for emergency medical service to the first shock was 12(6-26)min. The time from the first shock to the NIF administration was 25.5(9-264)min and the usage dose of NIF was 25(15-210)mg. When excluding 3 patients in whom percutaneous extracorporeal membrane oxygenation was applied before NIF administration, the rate of return of spontaneous circulation was 86% and the rate of admission alive to the hospital was 79%. One patient developed torsade de pointes. CONCLUSIONS: Intravenous administration of NIF seems to be feasible as a potential therapy for advanced cardiac life-support in patients with out-of-hospital VF, and therefore further study is warranted.

BACKGROUND: Although microvascular dysfunction following percutaneous coronary intervention (PCI) can be evaluated with the index of microcirculatory resistance (IMR), no method of treatment has been established. We hypothesized that intracoronary administration of nicorandil can improve IMR after successful primary PCI in patients with ST-segment elevation myocardial infarction (STEMI). METHODS AND RESULTS: In 40 patients with first STEMI after successful primary PCI, IMR was measured using PressureWire(TM) Certus (St. Jude Medical, MN, USA). In 20 of the patients (Group N), IMR was measured at baseline and after intracoronary nicorandil (2 mg/10 ml). In the other 20 patients (Control), IMR was measured at baseline, after intracoronary saline (10 ml) and after intracoronary nicorandil (2 mg/10 ml). In Group N, IMR significantly decreased after intracoronary nicorandil (median IMR, 27.7-18.7 U, P<0.0001). In the Control group, IMR did not change after saline administration (median IMR, 24.3-23.8 U, P=0.8193), but was significantly decreased after intracoronary nicorandil (median IMR, 23.8-14.9 U, P<0.0001). Next, all 40 patients were divided into subgroups by tertile of baseline IMR. In those with intermediate to high IMR (baseline IMR > or =21), intracoronary nicorandil significantly decreased IMR, although it did not change IMR in those with low IMR (baseline IMR <21). CONCLUSIONS: High IMR levels in patients with STEMI after successful primary PCI can be improved by intracoronary administration of nicorandil.
