Show moreCardiogenic shock (CS) complicating acute myocardial infarction (AMI) is associated with high morbidity and mortality. Our study aimed to gain insights into patient characteristics, outcomes and treatment strategies in CS patients. Patients with CS who underwent percutaneous coronary intervention (PCI) between 2017 and 2021 were identified in a nationwide registry. Data on medical history, laboratory values, angiographic features and outcomes were retrospectively assessed. A total of 2328 patients with a mean age of 66 years and of whom 73% were male, were included. Mortality at 30 days was 39% for the entire cohort. Non-survivors presented with a lower mean blood pressure and increased heart rate, blood lactate and blood glucose levels (p-value for all <0.001). Also, an increased prevalence of diabetes, multivessel coronary artery disease and a prior coronary event were found. Of all patients, 24% received mechanical circulatory support, of which the majority was via intra-aortic balloon pumps (IABPs). Furthermore, 79% of patients were treated with at least one vasoactive agent, and multivessel PCI was performed in 28%. In conclusion, a large set of hemodynamic, biochemical and patient-related characteristics was identified to be associated with mortality. Interestingly, multivessel PCI and IABPs were frequently applied despite a lack of evidence. Show less

Show moreBACKGROUNDExtracorporeal cardiopulmonary resuscitation (CPR) restores perfusion and oxy-genation in a patient who does not have spontaneous circulation. The evidencewith regard to the effect of extracorporeal CPR on survival with a favorable neu-rologic outcome in refractory out-of-hospital cardiac arrest is inconclusive.METHODSIn this multicenter, randomized, controlled trial conducted in the Netherlands, weassigned patients with an out-of-hospital cardiac arrest to receive extracorporealCPR or conventional CPR (standard advanced cardiac life support). Eligible patientswere between 18 and 70 years of age, had received bystander CPR, had an initialventricular arrhythmia, and did not have a return of spontaneous circulationwithin 15 minutes after CPR had been initiated. The primary outcome was sur-vival with a favorable neurologic outcome, defined as a Cerebral PerformanceCategory score of 1 or 2 (range, 1 to 5, with higher scores indicating more severedisability) at 30 days. Analyses were performed on an intention-to-treat basis.RESULTSOf the 160 patients who underwent randomization, 70 were assigned to receiveextracorporeal CPR and 64 to receive conventional CPR; 26 patients who did notmeet the inclusion criteria at hospital admission were excluded. At 30 days, 14 pa-tients (20%) in the extracorporeal-CPR group were alive with a favorable neuro-logic outcome, as compared with 10 patients (16%) in the conventional-CPR group(odds ratio, 1.4; 95% confidence interval, 0.5 to 3.5; P = 0.52). The number of seri-ous adverse events per patient was similar in the two groups.CONCLUSIONSIn patients with refractory out-of-hospital cardiac arrest, extracorporeal CPR andconventional CPR had similar effects on survival with a favorable neurologic out-come.

Show moreObjectives: The impact of atrial ischemia in the occurrence of atrial arrhythmiasmay vary based on the amount of jeopardized myocardium. We sought to determine the association between coronary flow impairment in dominant coronary atrial branches (CAB) and atrial arrhythmias at 1-year follow-up in ST-segment elevation myocardial infarction (STEMI) patients.Methods: Patients with STEMI involving the right or circumflex coronary artery were included. Dominant CAB was defined as the most developed CAB. Patients were followed-up during 1 year, including 24-h Holter ECG at 3 and 6months. Atrial arrhythmiaswere defined as atrial fibrillation/flutter, atrial tachycardia (>= 3 consecutive supraventricular ectopic beats) and excessive supraventricular ectopic activity (>30 supraventricular beats/h or runs >= 20 beats).Results: A dominant CAB was identified in 897 of 900 patients STEMI (age 61 +/- 12 years, 79% male). TIMI flow b 3 at the dominant CAB was present in 69 (8%) patients. Compared to those with dominant CAB preserved flow, patients with dominant CAB flow impairment presented with higher levels of troponin T (3.9 [2.2-8.2] vs. 3.1 [1.3-5.8], P= 0.008)and higher rates of atrial tachycardia at 3months (68% vs. 37%, P= 0.007) and more supraventricular ectopic beats both at 3 months (58 [21-235] vs. 33 [12-119], P = 0.02) and at 6 months (62 [24-156] vs. 32 [12-115]; P = 0.04) on 24-h Holter ECG. Age and an impaired coronary flow at the dominant CAB were independently related to a higher risk of developing atrial arrhythmias at 1-year follow-up.Conclusion: Dominant CAB flow impairment is infrequent and is associatedwith the occurrence of atrial arrhythmias, in the form atrial tachycardia and supraventricular ectopic beats, at follow-up.

Show moreObjectives We sought to assess the clinical value of adding intravascular ultrasound (IVUS) evaluation to coronary angiography (CA) to guide extrinsic left main coronary artery (LMCA) compression diagnosis and treatment in pulmonary hypertension (PH). Background LMCA compression due to a pulmonary artery aneurysm (PAA) is a severe complication of PH. Although guidelines encourage the use of IVUS for LMCA disease evaluation, it has hardly been used in this scenario. Methods We analyzed morbimortality of type 1 and 4 PH patients with clinically suspected LMCA compression by a PAA between 2010 and 2018 in a reference unit. LMCA compression was prospectively assessed with CA +/- IVUS. Angiographic-LMCA compression was considered conclusive when LMCA stenosis>50% was present in four predetermined projections; inconclusive, when LMCA stenosis>50% was present in 50% was present. Patients with conclusive and inconclusive CA underwent IVUS. IVUS-LMCA compression was defined as systolic minimum lumen area < 6 mm(2). Results LMCA compression was suspected in 23/796 patients (3%). CA was conclusive for compression in 7(30.5%), inconclusive in 9(39%), and negative in 7(30.5%). IVUS confirmed LMCA compression in 6/7(86%) patients with conclusive CA and in 2/9(22%) with inconclusive CA. Patients fulfilling IVUS criteria for LMCA compression underwent stent implantation. At 20 months follow-up a composite end-point of death, stent restenosis/thrombosis, or lung transplant was reported in three patients (13%). Conclusions CA can misdiagnose LMCA extrinsic compression. IVUS discriminates better whether significant compression by a PAA exists or not, avoiding unnecessary LMCA stenting. Patients treated following this strategy show a low rate of major clinical events at 20 months follow-up. Show less

Show moreWe present the case of a 45-year-old patient who was brought to our emergency department with an out-of-hospital cardiac arrest. The patient arrived 45 minutes after collapse due to ventricular fibrillation. The initial rhythm at arrival to the emergency department was asystole. His laboratory results showed profound lactic acidosis (lactate of 21 mmol/l and pH of 6.6). Time to arrival, rhythm at presentation and the observed lactic acidosis were all interpreted as prognostic signs of a poor outcome but, despite that, it was decided to treat the patient with extracorporeal cardiopulmonary resuscitation (ECPR). Subsequently percutaneous coronary intervention was performed. In contrast to the poor prognosis, the patient was discharged on day 6 with no discernible neurological deficit. This case illustrates that despite biochemical data suggesting profound tissue ischaemia/hypoxia, the outcome of ECPR may be excellent. Such data cannot be reliably used as a single indicator to decide whether or not ECPR should be initiated. Show less

Show moreObjectives To evaluate the frequency of procedural-related atrial branch occlusion in ST-segment elevation myocardial infarction (STEMI) patients and its association with atrial arrhythmias at 1-year follow-up.Background Atrial ischemia due to procedural-related coronary atrial branch occlusion in elective percutaneous coronary intervention (PCI) has been associated with atrial arrhythmias. Its role in a STEMI scenario is unknown.Methods STEMI patients treated with primary PCI were classified according to the loss or patency of an atrial branch at the end of the procedure. The occurrence of atrial arrhythmias was documented on 24-hr Holter-ECG at 3 and 6 months or on ECG during 1-year follow-up visits.Results Of 900 patients, 355 (age 61 +/- 12 years, 79% male) underwent primary PCI involving the origin of an atrial branch. Procedural-related coronary atrial branch occlusion was observed in 18 (5%) individuals). During 1-year follow-up, 33% of patients with procedural-related atrial branch occlusion presented atrial arrhythmias, as compared with 55% in those with a patent atrial branch (p = .088). Age, no previous history of myocardial infarction, and a reduced flow in the culprit vessel were the only independent correlates of atrial arrhythmias.Conclusions The frequency of procedural-related atrial branch occlusion during primary PCI is low (5%) and is not associated with increased frequency of atrial arrhythmias at 1-year follow-up.

Show moreBackground Return of spontaneous circulation occurs in less than 10% of patients with cardiac arrest undergoing cardiopulmonary resuscitation (CPR) for more than 15 minutes. Studies suggest that extracorporeal life support during cardiopulmonary resuscitation (ECPR) improves survival rate in these patients. These studies, however, are hampered by their non-randomized, observational design and are mostly single-center. A multicenter, randomized controlled trial is urgently warranted to evaluate the effectiveness of ECPR.Hypothesis We hypothesize that early initiation of ECPR in refractory out-of-hospital cardiac arrest (OHCA) improves the survival rate with favorable neurological status.Study design The INCEPTION trial is an investigator-initiated, prospective, multicenter trial that will randomly allocate 110 patients to either continued CPR or ECPR in a 1: 1 ratio. Patients eligible for inclusion are adults (<= 70 years) with witnessed OHCA presenting with an initial rhythm of ventricular fibrillation (VF) or ventricular tachycardia (VT), who received bystander basic life support and who fail to achieve sustained return of spontaneous circulation within 15 minutes of cardiopulmonary resuscitation by emergency medical services. The primary endpoint of the study is 30-day survival rate with favorable neurological status, defined as 1 or 2 on the Cerebral Performance Category score. The secondary endpoints include 3, 6 and 12-month survival rate with favorable neurological status and the cost-effectiveness of ECPR compared to CCPR.Summary The INCEPTION trial aims to determine the clinical benefit for the use of ECPR in patients with refractory OHCA presenting with VF/VT. Additionally, the feasibility and cost-effectiveness of ECPR will be evaluated. Show less

Show moreDetection of pulmonary artery aneurysms (PAA) in pulmonary arterial hypertension (PAH) is increasing. We sought to determine the frequency of PAA in a PAH cohort, variables related to its development and its prognostic impact. We conducted a retrospective analysis of PAH patients who underwent a computed tomography or magnetic resonance. PAA was defined as a pulmonary artery >40 mm. Baseline, echocardiographic, and hemodynamic findings at PAH diagnosis were compared. Freedom from death or lung transplant was estimated by Kaplan-Meier method and compared by logrank test. Predictors of PAA development were analyzed with multivariate models. Two-hundred patients underwent a computed tomography and/or magnetic resonance. In 77 (38%), a PAA (48.3 +/- 7.2 mm) was detected. Time-course (months) of PAH was an independent risk factor for PAA (hazard ratio 1.01; 95% confidence interval 1.002 to 1.019; p = 0.016) whilst connective tissue disease was associated with a lower risk (hazard ratio 0.236; 95% confidence interval 0.060 to 0.920; p = 0.037). PAA patients showed lower rates of death and lung transplant from PAH diagnosis (p = 0.005), but no differences appeared when survival analysis was performed from first imaging test (p = 0.269). PAA patients presented a nonsignificant higher rate of sudden death (5% PAA vs 1% noPAA; p = 0.073). In conclusion, the frequency of PAA was 38%. PAH time-course was an independent risk factor for PAA development whereas connective tissue disease -related PAH patients showed a lower risk. PAA patients showed lower rates of death or lung transplant from PAH diagnosis but no differences were found from imaging test. PAA patients had a nonsignificant higher rate of sudden death.
