Clinical outcomes associated with catecholamine use in patients diagnosed with Takotsubo cardiomyopathy

Background: Recent hypotheses have suggested the pathophysiological role of catecholamines in the evolution of the Takotsubo syndrome (TTS). The extent of cardiac and circulatory compromise dictates the use of some form of supportive therapy. This study was designed to investigate the clinical outcomes associated with catecholamine use in TTS patients. Methods: Our institutional database constituted a collective of 114 patients diagnosed with TTS between 2003 and 2015. The study-patients were subsequently classified into two groups based on the need for catecholamine support during hospital stay (catecholamine group n = 93; 81%, non-catecholamine group = 21; 19%). The primary end-point of our study was all-cause mortality. Results: Patients receiving catecholamine support showed higher grades of circulatory and cardiac compromise (left ventricular ejection fraction (LVEF) 39.6% vs. 32.7%, p-value < 0.01) and the course of disease was often complicated by the occurrence of different TTS-associated complications. The in-hospital mortality (3.2% vs. 28.5%, p < 0.01), 30-day mortality (17.2% vs. 51.4%, p < 0.01) as well as long-term mortality (38.7% vs. 80.9%, p < 0.01) was significantly higher in the group of patients receiving catecholamine support. A multivariate Cox regression analysis attributed EF ≤ 35% (HR 3.6, 95% CI 1.6–8.1; p < 0.01) and use of positive inotropic agents (HR 2.2, 95% CI 1.0–4.8; p 0.04) as independent predictors of the adverse outcome. Conclusion: Rates of in-hospital events and short- as well as long-term mortality were significantly higher in TTS patients receiving catecholamine support as compared to the other study-patients. These results need further evaluation in pre-clinical and clinical trials to determine if external catecholamines contribute to an adverse clinical outcome already compromised by the initial insult

spotlight europe 2009/10, October 2009: After Soccer Diplomacy: The Turkish-Armenian Relations

The protocols on the normalization of relations between Turkey and Armenia were signed in Zurich on 10 October 2009. Neither of the two issued a statement after the signing ceremony, since it could have gone beyond the finely balanced contents of the protocols. What are the expectations, hopes and fears associated with the reopening of the border and the normalization of relations? A report from four capitals and the EU

Cardiac Arrhythmias in Post-COVID Syndrome: Prevalence, Pathology, Diagnosis, and Treatment

An increase in post-COVID patients with late sequelae of acute COVID-19 infection is emerging as an ongoing challenge for physicians and healthcare professionals. Since the beginning of the pandemic, it has rapidly become evident that the acute infection is not limited to the respiratory tract but that several organs, including the cardiovascular system, can be affected. Moreover, in a significant proportion of patients (ranging from about 10 to up to 50%) with former COVID-19, cardiopulmonary symptoms such as dyspnea, palpitations, restricted physical capacity, and cardiac arrhythmias can persist weeks and months after the acute SARS-CoV-2 infection. The spectrum of COVID-19-associated arrhythmias is rather wide, most likely due to various pathomechanisms. In this article, the prevalence of cardiac arrhythmias and underlying pathologies are reviewed, including direct myocardial injury and abnormal consequences with an impact on cardiac electric instability. The hyperinflammatory reaction of the host immune system is specifically considered. Moreover, several distinct rhythm disorders occurring in post-COVID patients are discussed with regard to their clinical management

Novel Aspects Targeting Platelets in Atherosclerotic Cardiovascular Disease—A Translational Perspective

Platelets are important cellular targets in cardiovascular disease. Based on insights from basic science, translational approaches and clinical studies, a distinguished anti-platelet drug treatment regimen for cardiovascular patients could be established. Furthermore, platelets are increasingly considered as cells mediating effects “beyond thrombosis”, including vascular inflammation, tissue remodeling and healing of vascular and tissue lesions. This review has its focus on the functions and interactions of platelets with potential translational and clinical relevance. The role of platelets for the development of atherosclerosis and therapeutic modalities for primary and secondary prevention of atherosclerotic disease are addressed. Furthermore, novel therapeutic options for inhibiting platelet function and the use of platelets in regenerative medicine are considered

Copeptin reliably reflects longitudinal right ventricular function

Background: Data is limited evaluating novel biomarkers in right ventricular dysfunction. Normal right heart function improves the prognosis of patients with heart failure. Therefore, this study investigates the association between the novel biomarker copeptin and right heart function compared to NT-proBNP. Methods: Patients undergoing routine echocardiography were enrolled prospectively. Right ventricular function was assessed by tricuspid annular plane systolic excursion (TAPSE) and further right ventricular and atrial parameters. Exclusion criteria were age under 18 years, left ventricular ejection fraction < 50% and moderate to severe valvular heart disease. Blood samples were taken for biomarker measurements within 72 h of echocardiography. Results: Ninety-one patients were included. Median values of copeptin increased significantly according to decreasing values of TAPSE (P = 0.001; right heart function grade I: tricuspid annular plane systolic excursion; TAPSE > 24 mm: 5.20 pmol/L; grade II: TAPSE 18–24 mm: 8.10 pmol/L; grade III: TAPSE < 18 mm: 26.50 pmol/L). Copeptin concentrations were able to discriminate patients with decreased right heart function defined as TAPSE < 18 mm (area under the curves [AUC]: copeptin: 0.793; P = 0.001; NT-proBNP: 0.805; P = 0.0001). Within a multivariable linear regression model, copeptin was independently associated with TAPSE (copeptin: T: –4.43; P = 0.0001; NT-proBNP: T: –1.21; P = 0.23). Finally, copeptin concentrations were significantly associated with severely reduced right heart function (TAPSE < 18 mm) within a multivariate logistic regression model (copeptin: odds ratio: 0.94; 95% confidence interval: 0.911–0.975; P = 0.001). Conclusions: This study demonstrates that the novel biomarker copeptin reflects longitudinal right heart function assessed by standardized transthoracic echocardiography compared with NT-proBNP

Endovascular treatment of posterior circulation aneurysms: Results from a single-team experience of 81 cases including 13 flow diversion treatment.

Introduction:Relatively constant surgical risks and rapid advances in endovascular treatment have caused a major shift toward endovascular management of posterior circulation aneurysms. This paper presents the results of a series of endovascularly treated posterior circulation aneurysms.Methods:A total of 81 patients who underwent endovascular treatment of posterior circulation aneurysms performed by a single team between 2009 and 2019 were included. Demographic, clinical, radiologic, and management details were retrospectively obtained from hospital records.Results:Among the included patients, 50 (61.7%) and 31 (38.3%) were female and male, respectively. Subarachnoid hemorrhage was observed in 30 patients (37%). Moreover, 40 (49.3%) aneurysms were treated with stent-assisted coiling, 1 (1.2%) aneurysm was treated with parent artery occlusion, 2 (2.4%) aneurysms were coiled using balloon assistance, 24 (29.6%) aneurysms were coiled primarily, 1 (1.2%) patient had an unsuccessful treatment attempt, and 13 (16.0%) aneurysms were treated with flow-diverter stents or stent monotherapy. During the last follow-up, 57 (83.8%) aneurysms were completely occluded, whereas 6 (8.8%) and 2 (2.9%) aneurysms did and did not have a residual neck, respectively. Flow diversion was used to treat 13 patients, among whom 8 had total occlusion or stable residue. A total of 7 deaths (8.6%) were encountered in this series.Conclusion:Endovascular treatment should be considered as the primary treatment modality for posterior circulation aneurysms. Despite the high morbidity and mortality rates, promising results can be achieved with correct patient selection. Flow diversion can be a feasible alternative for complex aneurysms that are difficult to treat.Keywords:Aneurisma; Aneurysm; Circulación posterior; Endovascular; Hemorragia subaracnoidea; Posterior circulation; Stent; Subarachnoid hemorrhage
