Mortality in patients with normal left ventricular function requiring emergency VA-ECMO for postcardiotomy cardiogenic shock due to coronary malperfusion. PLoS One 2024; 19:e0300568. [PMID: 38512920 PMCID: PMC10956859 DOI: 10.1371/journal.pone.0300568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 02/29/2024] [Indexed: 03/23/2024] Open
Abstract
OBJECTIVES To analyze outcomes in patients with normal preoperative left ventricular ejection fraction (LVEF) undergoing venoarterial extracorporeal membrane oxygenation (VA-ECMO) therapy due to postcardiotomy cardiogenic shock (PCCS) related to coronary malperfusion. METHODS Retrospective single-center analysis in patients with normal preoperative LVEF treated with VA-ECMO for coronary malperfusion-related PCCS between May 1998 and May 2018. The primary outcome was 30-day mortality, which was compared using the Kaplan-Meier method and the log-rank test. Multivariable logistic regression was performed to identify predictors of mortality. RESULTS During the study period, a total of 62,125 patients underwent cardiac surgery at our institution. Amongst them, 59 patients (0.1%) with normal preoperative LVEF required VA-ECMO support due to coronary malperfusion-related PCCS. The mean duration of VA-ECMO support was 6 days (interquartile range 4-7 days). The 30-day mortality was 50.8%. Under VA-ECMO therapy, a complication composite outcome of bleeding, re-exploration for bleeding, acute renal failure, acute liver failure, and sepsis occurred in 51 (86.4%) patients. Independent predictors of 30-day mortality were lactate levels > 9.9 mmol/l before VA-ECMO implantation (odds ratio [OR]: 3.3; 95% confidence interval [CI] 1.5-7.0; p = 0.002), delay until revascularization > 278 minutes (OR: 2.9; 95% CI 1.3-6.4; p = 0.008) and peripheral arterial artery disease (OR: 3.3; 95% 1.6-7.5; p = 0.001). CONCLUSIONS Mortality rates are high in patients with normal preoperative LVEF who develop PCCS due to coronary malperfusion. The early implantation of VA-ECMO before the development of profound tissue hypoxia and early coronary revascularization increases the likelihood of survival. Lactate levels are useful to define optimal timing for the VA-ECMO initiation.

Coronary Angiography After Out-of-Hospital Cardiac Arrest Without ST-Segment Elevation: One-Year Outcomes of a Randomized Clinical Trial. JAMA Cardiol 2023; 8:827-834. [PMID: 37556123 PMCID: PMC10413219 DOI: 10.1001/jamacardio.2023.2264] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Accepted: 05/08/2023] [Indexed: 08/10/2023]
Abstract
Importance Myocardial infarction is a frequent cause of out-of-hospital cardiac arrest (OHCA). The long-term effect of early coronary angiography on patients with OHCA with possible coronary trigger but no ST-segment elevation remains unclear. Objective To compare the clinical outcomes of early unselective angiography with the clinical outcomes of a delayed or selective approach for successfully resuscitated patients with OHCA of presumed cardiac origin without ST-segment elevation at 1-year follow-up. Design, Setting, and Participants The TOMAHAWK trial was a multicenter, international (Germany and Denmark), investigator-initiated, open-label, randomized clinical trial enrolling 554 patients between November 23, 2016, to September 20, 2019. Patients with stable return of spontaneous circulation after OHCA of presumed cardiac origin but without ST-segment elevation on the postresuscitation electrocardiogram were eligible for inclusion. A total of 554 patients were randomized to either immediate coronary angiography after hospital admission or an initial intensive care assessment with delayed or selective angiography after a minimum of 24 hours. All 554 patients were included in survival analyses during the follow-up period of 1 year. Secondary clinical outcomes were assessed only for participants alive at 1 year to account for the competing risk of death. Interventions Early vs delayed or selective coronary angiography and revascularization if indicated. Main Outcomes and Measures Evaluations in this secondary analysis included all-cause mortality after 1 year, as well as severe neurologic deficit, myocardial infarction, and rehospitalization for congestive heart failure in survivors at 1 year. Results A total of 281 patients were randomized to the immediate angiography group and 273 to the delayed or selective group, with a median age of 70 years (IQR, 60-78 years). A total of 369 of 530 patients (69.6%) were male, and 268 of 483 patients (55.5%) had a shockable arrest rhythm. At 1 year, all-cause mortality was 60.8% (161 of 265) in the immediate angiography group and 54.3% (144 of 265) in the delayed or selective angiography group without significant difference between the treatment strategies, trending toward an increase in mortality with immediate angiography (hazard ratio, 1.25; 95% CI, 0.99-1.57; P = .05). For patients surviving until 1 year, the rates of severe neurologic deficit, myocardial infarction, and rehospitalization for congestive heart failure were similar between the groups. Conclusions and Relevance This study found that a strategy of immediate coronary angiography does not provide clinical benefit compared with a delayed or selective invasive approach for patients 1 year after resuscitated OHCA of presumed coronary cause and without ST-segment elevation.

Incidence and Outcomes of Emergency Intraprocedural Surgical Conversion during Transcatheter Aortic Valve Implantation: Insights from a Large Tertiary Care Centre. Eur J Cardiothorac Surg 2023:7110896. [PMID: 37027228 DOI: 10.1093/ejcts/ezad142] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 03/06/2023] [Accepted: 04/05/2023] [Indexed: 04/08/2023] Open
Abstract
OBJECTIVE In transcatheter aortic valve implantation (TAVI), intraprocedural complications, which are only manageable by conversion to emergency open-heart surgery (E-OHS), occasionally occur. Contemporary data on the incidence and outcome of TAVI patients undergoing E-OHS are scarce. METHODS Data of all patients undergoing transfemoral TAVI between 2006 and 2020 at the Heart Centre Leipzig were analyzed. The study time was divided into 3 periods: 2006-2010 (P1), 2011-2015 (P2), 2016-2020 (P3). Patients were grouped according to their surgical risk (high risk: EuroSCORE II ≥ 6%, low/intermediate risk: EuroSCORE II < 6%). Primary outcomes were intraprocedural and in-hospital mortality, and1-year survival. RESULTS During the study period, a total of 6903 patients underwent transfemoral TAVI. Among them, 74 (1.1%) required E-OHS [high risk, n = 66 (89.2%); low/intermediate risk, n = 8 (10.8%)]. The rate of patients requiring E-OHS was 3.5% (20/577 patients), 1.8% (35/1967 patients), and 0.4% (19/4359 patients) in study periods P1-P3, respectively (p < 0.001). The proportion of E-OHS patients who were low/intermediate risk considerably increased over time (P1:0%; P28.6%; P3:26.3%; p = 0.077). Intraprocedural mortality occurred in 10 patients (13.5%), all of which were high-risk. In-hospital mortality was 62.1% in high-risk patients and 12.5% in low/intermediate risk patients (p = 0.007). One-year survival was 37.8% in all patients undergoing E-OHS, 31.8% in high-risk patients, and 87.5% in low/intermediate risk patients (Log-rank p = 0.002). CONCLUSIONS In-hospital and 1-year survival rates following E-OHS are higher in low/intermediate risk than high risk TAVI patients. An on-site cardiac surgical department with immediately available E-OHS capabilities is an important component of the TAVI team.

Abstract
Background In the absence of randomized controlled trials, reports from nonrandomized studies comparing valve-in-valve implantation (ViV) to redo surgical aortic valve replacement (rAVR) have shown inconsistent results. Methods and Results PubMed/MEDLINE, Google Scholar, and CENTRAL (Cochrane Central Register of Controlled Trials) were searched through December 2021. Meta-Analysis of Observational Studies in Epidemiology guidelines were followed. The protocol was registered at the International Prospective Register of Systematic Reviews. Random effects models were applied. The primary outcomes of interest were short-term and midterm mortality. Secondary outcomes included stroke, myocardial infarction, acute renal failure, and permanent pacemaker implantation, as well as prosthetic aortic valve regurgitation, mean transvalvular gradient, and severe prosthesis-patient mismatch. Of 8881 patients included in 15 studies, 4458 (50.2%) underwent ViV and 4423 (49.8%) rAVR. Short-term mortality was 2.8% in patients undergoing ViV compared with 5.0% in patients undergoing rAVR (risk ratio [RR] 0.55 [95% CI, 0.34-0.91], P=0.02). Midterm mortality did not differ in patients undergoing ViV compared with patients undergoing rAVR (hazard ratio, 1.27 [95% CI, 0.72-2.25]). The rate of acute kidney failure was lower following ViV, (RR, 0.54 [95% CI, 0.33-0.88], P=0.02), whereas prosthetic aortic valve regurgitation (RR, 4.18 [95% CI, 1.88-9.3], P=0.003) as well as severe patient-prothesis mismatch (RR, 3.12 [95% CI, 2.35-4.1], P<0.001) occurred more frequently. The mean transvalvular gradient was higher following ViV (standard mean difference, 0.44 [95% CI, 0.15-0.72], P=0.008). There were no significant differences between groups with respect to stroke (P=0.26), myocardial infarction (P=0.93), or pacemaker implantation (P=0.21). Conclusions Results of this meta-analysis demonstrate better short-term mortality after ViV compared with rAVR. Midterm mortality was similar between groups. Given the likely selection bias in these individual reports, an adequately powered multicenter randomized clinical trial with sufficiently long follow-up in patients with low-to-intermediate surgical risk is warranted.

Abstract
Purpose To assess the diagnostic potential of texture analysis applied to T1 and T2 maps obtained with cardiac MRI for the diagnosis of acute infarctlike myocarditis. Materials and Methods This prospective study from August 2012 to May 2015 included 39 participants (overall mean age ± standard deviation, 34.7 years ± 12.2 [range, 18-63 years]; mean age of women, 46.1 years ± 10.8 [range, 24-63 years]; mean age of men, 29.8 years ± 9.2 [range, 18-56 years]) from the Magnetic Resonance Imaging in Myocarditis (MyoRacer) trial with clinical suspicion of acute myocarditis and infarctlike presentation. Participants underwent biventricular endomyocardial biopsy, cardiac catheterization, and cardiac MRI at 1.5 T, in which native T1 and T2 mapping as well as Lake Louise criteria (LLC) were assessed. Texture analysis was applied on T1 and T2 maps by using a freely available software package. Stepwise dimension reduction and texture feature selection was performed for selecting features enabling the diagnosis of myocarditis by using endomyocardial biopsy as the reference standard. Results Endomyocardial biopsy confirmed the diagnosis of acute myocarditis in 26 patients, whereas 13 participants had no signs of acute inflammation. Mean T1 and T2 values and LLC showed a low diagnostic performance, with area under the curve in receiver operating curve analyses as follows: 0.65 (95% confidence interval [CI]: 0.45, 0.85) for T1, 0.67 (95% CI: 0.49, 0.85) for T2, and 0.62 (95% CI: 0.42, 0.79) for LLC. Combining the texture features T2 run-length nonuniformity and gray-level nonuniformity resulted in higher diagnostic performance with an area under the curve of 0.88 (95% CI: 0.73, 1.00) (P < .001) and a sensitivity and specificity of 89% [95% CI: 81%, 93%] and 92% [95% CI: 77%, 93%], respectively. Conclusion Texture analysis of T2 maps shows high sensitivity and specificity for the diagnosis of acute infarctlike myocarditis. © RSNA, 2018 Online supplemental material is available for this article.

Abstract
AIMS The aim of the current study was to investigate the impact of a chronic total occlusion (CTO) in a non-infarct-related coronary artery (non-IRA) on one-year mortality and occurrence of cardiac arrhythmia in patients with cardiogenic shock (CS) complicating acute myocardial infarction (AMI). METHODS AND RESULTS In a retrospective sub-analysis of the Intraaortic Balloon Pump in Cardiogenic Shock II trial (IABP-SHOCK II) and its accompanying registry, 201 (26%) of 761 patients had a CTO in a non-IR major coronary artery. Mortality was significantly higher in the CTO group at day of admission (19% vs. 11%; p=0.005), 30 days (53% vs. 41%, p=0.002), and 12 months (63% vs. 51%, p=0.002). In the adjusted multivariate Cox regression analysis, a CTO in a non-IRA was an independent predictor of mortality at 12 months (hazard ratio 1.30, 95% confidence interval [CI]: 1.02-1.67, p=0.03). At 30-day follow-up, ventricular arrhythmias requiring defibrillation occurred more frequently in patients with non-IRA CTO in the univariate analysis (33% vs. 21%, odds ratio 1.83, 95% CI: 1.28-2.62, p=0.002). CONCLUSIONS In patients with CS complicating AMI, the presence of CTO in a non-IRA is associated with a higher incidence of ventricular arrhythmias and is an independent predictor of mortality at 12-month follow-up.

Abstract
BACKGROUND In patients who have acute myocardial infarction with cardiogenic shock, early revascularization of the culprit artery by means of percutaneous coronary intervention (PCI) improves outcomes. However, the majority of patients with cardiogenic shock have multivessel disease, and whether PCI should be performed immediately for stenoses in nonculprit arteries is controversial. METHODS In this multicenter trial, we randomly assigned 706 patients who had multivessel disease, acute myocardial infarction, and cardiogenic shock to one of two initial revascularization strategies: either PCI of the culprit lesion only, with the option of staged revascularization of nonculprit lesions, or immediate multivessel PCI. The primary end point was a composite of death or severe renal failure leading to renal-replacement therapy within 30 days after randomization. Safety end points included bleeding and stroke. RESULTS At 30 days, the composite primary end point of death or renal-replacement therapy had occurred in 158 of the 344 patients (45.9%) in the culprit-lesion-only PCI group and in 189 of the 341 patients (55.4%) in the multivessel PCI group (relative risk, 0.83; 95% confidence interval [CI], 0.71 to 0.96; P=0.01). The relative risk of death in the culprit-lesion-only PCI group as compared with the multivessel PCI group was 0.84 (95% CI, 0.72 to 0.98; P=0.03), and the relative risk of renal-replacement therapy was 0.71 (95% CI, 0.49 to 1.03; P=0.07). The time to hemodynamic stabilization, the risk of catecholamine therapy and the duration of such therapy, the levels of troponin T and creatine kinase, and the rates of bleeding and stroke did not differ significantly between the two groups. CONCLUSIONS Among patients who had multivessel coronary artery disease and acute myocardial infarction with cardiogenic shock, the 30-day risk of a composite of death or severe renal failure leading to renal-replacement therapy was lower among those who initially underwent PCI of the culprit lesion only than among those who underwent immediate multivessel PCI.

Abstract
BACKGROUND Cardiac magnetic resonance (CMR) demonstrated great potential for the prediction of major adverse cardiac events (MACE) in ST-segment-elevation myocardial infarction. The aim of this study was to develop and validate a CMR-based risk score for ST-segment-elevation myocardial infarction patients. METHODS AND RESULTS The scoring model was developed and validated on ST-segment-elevation myocardial infarction cohorts from 2 independent randomized controlled trials (n=738 and n=458 patients, respectively) and included left ventricular (LV) ejection fraction, infarct size, and microvascular obstruction. Primary end point was the 12-month MACE rate consisting of death, reinfarction, and new congestive heart failure. In the derivation cohort, LV ejection fraction ≤47%, infarct size ≥19%LV, and microvascular obstruction ≥1.4%LV were identified as the best cutoff values for MACE prediction. According to the hazard ratios in multivariable regression analysis, the CMR risk score was created by attributing 1 point for LV ejection fraction ≤47%, 1 point for infarct size ≥19%LV, and 2 points for microvascular obstruction ≥1.4%LV. In the validation cohort, the score showed a good prediction of MACE (area under the curve: 0.76). Stratification into a low (0/1 point) and high-risk group (≥2 points) resulted in significantly higher MACE rates in high-risk patients (9.0% versus 2.2%; P=0.001). Inclusion of the CMR score in addition to a model of clinical risk factors led to a significant increase of C statistics from 0.74 to 0.83 (P=0.037), a net reclassification improvement of 0.18 (P=0.009), and an integrated discriminative improvement of 0.04 (P=0.010). CONCLUSIONS Our approach integrates the prognostic information of CMR imaging into a simple risk score that showed incremental prognostic value over clinical risk factors in ST-segment-elevation myocardial infarction patients.

Abstract
AIMS Studies comparing reperfusion efficacy and myocardial damage between diabetic and non-diabetic patients with ST-elevation myocardial infarction (STEMI) are scarce and have reported conflicting results. The aim was to investigate the impact of preadmission diabetic status on myocardial salvage and damage as determined by cardiac magnetic resonance (CMR), and to evaluate its prognostic relevance. MATERIALS AND METHODS We enrolled 792 patients with STEMI at 8 sites. CMR core laboratory analysis was performed to determine infarct characteristics. Major adverse cardiac events (MACE), defined as a composite of all-cause death, non-fatal re-infarction and new congestive heart failure, were recorded at 12 months. Patients were categorized according to preexisting diabetes mellitus (DM), and according to insulin-treated DM (ITDM) and non-insulin-treated DM (NITDM). RESULTS One-hundred and sixty (20%) patients had DM and 74 (9%) were insulin-treated. There was no difference in the myocardial salvage index, infarct size, microvascular obstruction and left ventricular ejection fraction between all patient groups (all P > .05). Patients with DM were at higher risk of MACE (11% vs 6%, P = .03) than non-DM patients. After stratification according to preadmission anti-diabetic therapy, MACE rate was comparable between NITDM and non-DM (P > .05), whereas the group of ITDM patients had significantly worse outcome (P < .001). CONCLUSIONS Diabetic patients with STEMI, especially those having ITDM, had an increased risk of MACE. The adverse clinical outcome was, however, not explained by an impact of DM on reperfusion success or myocardial damage. Clinical trial registry number: NCT00712101.

Abstract
INTRODUCTION Emergency percutaneous coronary intervention (PCI) of the culprit lesion for patients with acute myocardial infarctions is an accepted practice. A majority of patients present with multivessel disease with additional relevant stenoses apart from the culprit lesion. In haemodynamically stable patients, there is increasing evidence from randomised trials to support the practice of immediate complete revascularisation. However, in the presence of cardiogenic shock, the optimal management strategy for additional non-culprit lesions is unknown. A multicentre randomised controlled trial, CULPRIT-SHOCK, is examining whether culprit vessel only PCI with potentially subsequent staged revascularisation is more effective than immediate multivessel PCI. This paper describes the intended economic evaluation of the trial. METHODS AND ANALYSIS The economic evaluation will be conducted using a pre-trial decision model and within-trial analysis. The modelling-based analysis will provide expected costs and health outcomes, and incremental cost-effectiveness ratio over the lifetime for the cohort of patients included in the trial. The within-trial analysis will provide estimates of cost per life saved at 30 days and in 1 year, and estimates of health-related quality of life. Bootstrapping and cost-effectiveness acceptability curves will be used to address any uncertainty around these estimates. Different types of regression models within a generalised estimating equation framework will be used to examine how the total cost and quality-adjusted life years are explained by patients' characteristics, revascularisation strategy, country and centre. The cost-effectiveness analysis will be from the perspective of each country's national health services, where costs will be expressed in euros adjusted for purchasing power parity. ETHICS AND DISSEMINATION Ethical approval for the study was granted by the local Ethics Committee at each recruiting centre. The economic evaluation analyses will be published in peer-reviewed journals of the concerned literature and communicated through the profiles of the authors at www.twitter.com and www.researchgate.net. TRIAL REGISTRATION NUMBER NCT01927549; Pre-results.

Abstract
Percutaneous mechanical circulatory support devices, such as intra-aortic balloon pump (IABP), active left ventricular assist devices (LVAD) or extracorporeal life support (ECLS), are treatment options for selected patients in cardiogenic shock, undergoing cardiopulmonary resuscitation, or high-risk percutaneous coronary intervention and coronary artery bypass grafting. Potential benefits include the maintenance of organ function and the reduction of intracardiac pressures, volumes, and oxygen consumption. On the other hand, they are invasive, resource intensive, and can be associated with serious complications. Thus, their potential benefits must be weighed against the inherent risks. Despite the lack of sufficient scientific evidence, the use of mechanical circulatory support devices has risen considerably in recent years. This educational article covers practical issues of IABP, LVAD, and ECLS with respect to patient and device selection, implantation technique, potential complications, and future perspectives.

Abstract
Background: Early revascularisation of the culprit lesion is the therapeutic cornerstone in cardiogenic shock complicating acute myocardial infarction. The optimal management of additional non-culprit lesions is unclear. This systematic review and meta-analysis aims to summarise current evidence on the comparison of immediate multivessel percutaneous coronary intervention (MV-PCI) or culprit lesion only PCI with possible staged revascularisation (C-PCI) in patients with cardiogenic shock complicating acute myocardial infarction. Methods: Medical literature databases were screened to identify analyses comparing MV-PCI with C-PCI in patients with cardiogenic shock complicating acute myocardial infarction and multivessel coronary artery disease. In absence of randomised trials, 10 cohort studies were included in the current meta-analysis. The primary outcome of short-term mortality was assessed at hospital discharge or 30 days after hospital admission. Secondary outcomes were long-term mortality as well as myocardial re-infarction, stroke, acute renal failure, and bleeding at short-term follow-up. Results: Of 6051 patients, 1194 (19.7%) received MV-PCI and 4857 (80.3%) C-PCI. Short-term mortality was 37.5% in patients undergoing MV-PCI compared with 28.8% in C-PCI patients (risk ratio 1.26, 95% confidence interval 1.12–1.41, p=0.001). Long-term mortality ( p=0.77), myocardial re-infarction ( p=0.77), stroke ( p=0.12), acute renal failure ( p=0.17) and bleeding ( p=0.53) did not differ significantly between the two revascularisation groups. Conclusions: Results of this first meta-analysis on the interventional management of patients with cardiogenic shock complicating acute myocardial infarction and multivessel coronary artery disease do not support MV-PCI over C-PCI. However, possible treatment selection bias in the individual studies must be taken into account.

Abstract
OBJECTIVES This study assessed the prognostic significance of remote zone native T1 alterations for the prediction of clinical events in a population with ST-segment elevation myocardial infarction (STEMI) who were treated by primary percutaneous coronary intervention (PPCI) and compared it with conventional markers of infarct severity. BACKGROUND The exact role and incremental prognostic relevance of remote myocardium native T1 mapping alterations assessed by cardiac magnetic resonance (CMR) after STEMI remains unclear. METHODS We included 255 consecutive patients with STEMI who were reperfused within 12 h after symptom onset. CMR core laboratory analysis was performed to assess left ventricular (LV) function, standard infarct characteristics, and native T1 values of the remote, noninfarcted myocardium. The primary endpoint was a composite of death, reinfarction, and new congestive heart failure within 6 months (major adverse cardiac events [MACE]). RESULTS Patients with increased remote zone native T1 values (>1,129 ms) had significantly larger infarcts (p = 0.012), less myocardial salvage (p = 0.002), and more pronounced LV dysfunction (p = 0.011). In multivariable analysis, remote zone native T1 was independently associated with MACE after adjusting for clinical risk factors (p = 0.001) or other CMR variables (p = 0.007). In C-statistics, native T1 of remote myocardium provided incremental prognostic information beyond clinical risk factors, LV ejection fraction, and other markers of infarct severity (all p < 0.05). The addition of remote zone native T1 to a model of prognostic CMR parameters (ejection fraction, infarct size, and myocardial salvage index) led to net reclassification improvement of 0.82 (95% confidence interval: 0.46 to 1.17; p < 0.001) and to an integrated discrimination improvement of 0.07 (95% confidence interval: 0.02 to 0.13; p = 0.01). CONCLUSIONS In STEMI patients treated by PPCI, evaluation of remote zone alterations by quantitative noncontrast T1 mapping provided independent and incremental prognostic information in addition to clinical risk factors and traditional CMR outcome markers. Remote zone alterations may thus represent a novel therapeutic target and a useful parameter for optimized risk stratification.

Abstract
Background: The prognostic impact of pneumonia and signs of systemic inflammation in patients with acute decompensated heart failure (ADHF) has not been fully elucidated yet. The aim of the present study was thus to investigate the association of pneumonia and the inflammation surrogate C-reactive protein with all-cause mortality in patients admitted for ADHF. Methods: We analysed data of 1939 patients admitted for ADHF. Patients were dichotomised according to the presence or absence of pneumonia. The primary endpoint of all-cause mortality was determined by death registry linkage. Results: In total, 412 (21.2%) patients had concomitant pneumonia. Median C-reactive protein levels were higher in patients with compared to patients without pneumonia (24.9 versus 9.8 mg/l, respectively; P<0.001). All-cause mortality was significantly higher in patients with pneumonia ( P<0.001). In adjusted Cox regression models, pneumonia as well as C-reactive protein were independently associated with in-hospital mortality. Only C-reactive protein remained as independent predictor for long-term mortality. Conclusion: Pneumonia is relatively common in ADHF and a predictor for in-hospital mortality. However, inflammation in general seems to be more important than pneumonia itself for long-term prognosis. Compared to community-acquired pneumonia studies, C-reactive protein levels were rather low and therefore pneumonia might be over-diagnosed in ADHF patients.

Abstract
BACKGROUND Antecedent hypertension is associated with poor outcome in patients with ST-elevation myocardial infarction (STEMI). Whether differences in myocardial salvage, infarct size and microvascular injury contribute to the adverse outcome is unknown. We investigated the association between antecedent hypertension and cardiovascular magnetic resonance (CMR) parameters of myocardial salvage and damage in a multicenter CMR substudy of the AIDA-STEMI trial (Abciximab Intracoronary versus intravenously Drug Application in ST-elevation myocardial infarction). METHODS We analyzed 792 consecutive STEMI patients reperfused within 12 h after symptom onset. Patients underwent CMR imaging for assessment of myocardial salvage, infarct size and microvascular obstruction within 10 days after infarction. Major adverse cardiac events (MACE) were recorded at 12-month follow-up. RESULTS Antecedent hypertension was present in 540 patients (68 %) and was associated with a significantly increased baseline risk profile (advanced age, higher body mass index, higher incidence of diabetes, hypercholesterolemia, previous angioplasty and multivessel disease, p < 0.001 for all). MACE were more frequent in patients with hypertension as compared to patients without hypertension (45 [8 %] vs. 8 [3 %], p < 0.01). Antecedent hypertension remained an independent predictor of MACE after multivariate adjustment (hazard ratio 3.42 [confidence interval 1.45-8.08], p < 0.01). There was, however, no significant difference in the area at risk, infarct size, myocardial salvage index, extent of microvascular obstruction, and left ventricular ejection fraction between the groups (all p > 0.05). CONCLUSION Despite a higher rate of MACE in contemporary reperfused STEMI patients with antecedent hypertension, there was no difference in reperfusion efficacy, infarct size and reperfusion injury as visualized by CMR.

Abstract
Data on the impact of initial Thrombolysis In Myocardial Infarction (TIMI) flow in the culprit coronary artery on myocardial damage after ST-elevation myocardial infarction (STEMI) are limited. Aim of this multicenter study was, therefore, to elucidate the impact of TIMI flow grade before percutaneous coronary intervention (PCI) on infarct size (IS), myocardial salvage index (MSI), and microvascular obstruction (MVO) assessed by cardiac magnetic resonance (CMR) imaging in patients with STEMI. We enrolled 738 patients with STEMI reperfused by primary PCI within 12 hours after symptom onset at 8 centers. Impaired coronary flow was defined as an initial coronary TIMI flow grade ≤1, whereas preserved coronary flow was defined as an initial coronary TIMI flow grade ≥2. CMR was performed in median 3 days (interquartile range 2 to 4 days) after infarction using a standardized infarction protocol. IS, MVO, and MSI were determined in central core laboratory-masked analyses. The primary clinical end point of the study was the time to major adverse cardiac events defined as death, reinfarction, and new onset of heart failure within 12 months after infarction. TIMI flow ≤1 before PCI was present in 507 patients (68.7%) and was significantly associated with larger IS (19% left ventricular [LV] vs 9% LV; p <0.001), less MSI (0.46 vs 0.65; p <0.001), reduced left ventricular ejection fraction (49% vs 55%; p <0.001), and a higher extent of MVO (0.6% LV vs 0.0% LV; p <0.001). Moreover, TIMI flow before PCI was identified as an independent predictor of IS, MVO, and MSI. However, there were no significant differences in major adverse cardiac event rates between groups (6.1% vs 7.5%; p = 0.48). In conclusion, TIMI flow pre-PCI is reversely associated with myocardial injury and is an independent predictor of myocardial damage assessed by CMR.

Abstract
BACKGROUND Current guidelines recommend immediate multivessel percutaneous coronary intervention (PCI) in patients with cardiogenic shock, despite the lack of randomised trials. We sought to investigate the use and impact on outcome of multivessel PCI in comparison to culprit lesion only PCI in a retrospective analysis in patients with cardiogenic shock complicating acute myocardial infarction. METHODS AND RESULTS In the randomised IABP-SHOCK II trial, investigating the effect of intra-aortic balloon pump on outcome, 451 (75%) of the total of 600 patients had multivessel coronary artery disease and underwent PCI. Immediate multivessel PCI was performed in 167 (37%) patients. TIMI 3 patency after PCI in all treated vessels was observed in 83.2% versus 79.0% of patients after multivessel versus culprit lesion PCI, respectively. The 30-day (44.9% vs. 42.3%) and 12-month (54.8% vs. 52.7%) mortality rates did not significantly differ between the two groups. In the multivariate analysis multivessel PCI was not associated with an improved mortality after 12 months (odds ratio 0.92, 95% confidence intervals 0.69-1.21). CONCLUSION In this retrospective analysis of the largest randomised study in cardiogenic shock immediate multivessel PCI was used in approximately one third of patients with cardiogenic shock. There was no benefit with immediate multivessel PCI in comparison to culprit lesion only PCI. Therefore a randomised trial is needed to determine the definitive role of multivessel PCI in cardiogenic shock. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov , NCT00491036.

Abstract
BACKGROUND Data suggest that T1 and T2 mapping have excellent diagnostic accuracy in patients with suspected myocarditis. However, the true diagnostic performance of comprehensive cardiac magnetic resonance (CMR) mapping versus endomyocardial biopsy (EMB) has not been determined. OBJECTIVES This study assessed the performance of CMR imaging, including T1 and T2 mapping, compared with EMB in an unselected, consecutive patient cohort with suspected myocarditis. It also examined the potential role of CMR field strength by comparing 1.5-T versus 3.0-T imaging. METHODS Patients underwent biventricular EMB, cardiac catheterization (for exclusion of coronary artery disease), and CMR imaging on 1.5- and 3-T scanners. The CMR protocol included current standard Lake Louise criteria (LLC) for myocarditis as well as native T1, calculation of extracellular volume fraction (ECV), and T2 mapping (only on 1.5-T). Patients were divided into 2 groups according to symptom duration (acute: ≤14 days vs. chronic: >14 days). RESULTS A total of 129 patients underwent 1.5-T imaging. In patients with acute symptoms, native T1 yielded the best diagnostic performance as defined by the area under the curve (AUC) of receiver-operating curves (0.82) followed by T2 (0.81), ECV (0.75), and LLC (0.56). In patients with chronic symptoms, only T2 mapping yielded an acceptable AUC (0.77). On 3.0-T, AUCs of native T1, ECV, and LLC were comparable to 1.5-T with no significant differences. CONCLUSIONS In patients with acute symptoms, mapping techniques provide a useful tool for confirming or rejecting the diagnosis of myocarditis and are superior to the LLC. However, only T2 mapping has acceptable diagnostic performance in patients with chronic symptoms. (Magnetic Resonance Imaging in Myocarditis [MyoRacer]; NCT02177630).
