Abstract
Abstract
Background
Takotsubo syndrome (TTS) is featured by an acute and reversible left ventricular dysfunction and can be complicated by cardiogenic shock. Intra-aortic balloon pumping (IABP) use in this setting is controversial, and few data are available from large populations. Aim of this study was therefore to evaluate short- and long-term impact of IABP on mortality in TTS complicated by cardiogenic shock.
Methods
The GEIST registry is a multicenter, international registry on TTS involving 38 centers from Germany, Italy and Spain. Between 2006 and 2017, 2250 consecutive patients with TTS were enrolled.
Results
Of the 2250 patients, 211 (9%) experienced cardiogenic shock during hospitalization for TTS. Admission left ventricular ejection fraction (LVEF) was 30±15% and systolic blood pressure was 90±35 mmHg. Apical ballooning pattern was found in 77%, mid-ventricular/basal pattern in 11%, and 2% of the patients, respectively.
Forty-two patients out of 211 (19%) received IABP after coronary angiography. Patients receiving IABP compared to standard medical therapy did not differ in terms of age, gender, cardiovascular risk factors and admission LVEF.
No differences were found in term of in-hospital mortality (9.5% vs 17% p=0.35), length of hospitalization (19.3 vs 16.3 days p=0.34), need of invasive ventilation (35% vs 41% p=0.60), stroke (4.7% vs 11% p=0.17) and LV thrombus (0.5% vs 1.7%, p=0.98).
At long-term follow-up, with a median of 2 years, overall mortality in patients with cardiogenic shock and TTS was 34.1%. Mortality was not different between the IABP and the control group (33.7% vs 35.0%; p=0.85).
Conclusions
In this large multicenter observational registry, the use of IABP has no impact on mortality at short and long-term follow-up. Further studies are needed to evaluate the best therapeutic strategy in TTS complicated by cardiogenic shock.

Abstract
BACKGROUND Takotsubo Syndrome (TTS) is an acute reversible left ventricular dysfunction. Recently published studies have highlighted a similar mortality rate as acute coronary syndrome (ACS). We compared the impact of gender differences on the outcome of TTS patients as compared to ACS patient. DESIGN AND METHODS We included a collective of 138 patients TTS between 2003 and 2016 at our institution. Patients were divided according to their gender into two groups (Males n=21, 15% and females, n=117, 85%). They were compared with a cohort of 300 patients with a diagnosis of ACS. RESULTS On the acute phase, in male patients with TTS, a treatment with inotropic was more often required (33.3 vs. 11.5%, P<0.01), were more susceptible to cardiogenic shock (28.6 vs. 12.5%, P<0.04). Concerning the long-term prognosis after the acute event, male patients had higher all-cause mortality over long-term follow-up. A Kaplan-Meier analysis indicated that the mortality of male patients with TTS was significantly higher compared to male patients with ACS (log-rank <0.01), while there was no significant difference between female patients with TTS and ACS (log-rank =0.60, P=0.45). In a multivariate cox regression analysis, male gender (HR 2.7, 95% CI: 1.1-6.5, P=0.02) GFR <60 ml/min (HR 2.8, 95% CI: 1.2-6.0, P=0.01) and history of cancer (HR 3.6, 95% CI 1.4-9.3, P<0.01) were independent predictors of 5-year mortality. CONCLUSIONS Considerable evidence suggests that TTS compared to ACS implicates more significant clinical short-term events on male patients and it may be associated with poorer long-term prognosis.

Abstract
Atrial fibrillation (AF) is the most common form of cardiac tachyarrhythmia. It is estimated that in the Rhein-Neckar region approximately 40,000-50,000 out of 2 million people are affected. Due to demographic changes in the near future there will be a significant increase in the prevalence of AF within the next decades. The ARENA project was initiated by the Foundation Institute for Cardiac Infarction Research (IHF) Ludwigshafen in cooperation with cardiological and neurological departments of neighboring hospitals, resident doctors and pharmacies to improve the awareness and care of patients with AF. The particular aim is the prevention of stroke as one of the most dreaded complications. The project focusses on the following three subtopics: interventions, medication, migration. The aim of the intervention project is to raise awareness of AF as a risk factor for stroke and to improve the diagnostic work-up and care for patients with diagnosed or unknown AF. The subproject medication focusses on the adherence of patients with AF to the prescribed antithrombotic medication. To evaluate differences concerning patients with and without a migration background the subproject migration was initiated.

Abstract
The worldwide prevalence of heart failure is 1-2% with a portion of >10% in patients older than 70 years. In addition to treatment of causal determined factors and lifestyle modification, basic treatment consists of guideline-directed medical therapy with angiotensin-converting enzyme inhibitors (ACE), β‑blockers (BB), mineralocorticoid receptor antagonists (MRA), diuretics, digitalis (class IIb recommendation), angiotensin receptor blockers (ARB), Iƒ-channel blockers plus recently recommended in the guidelines angiotensin receptor neprilysin inhibitor (ARNI) to substitute the ACE inhibitor (class I b). Cardiac contractility modulation (CCM) is a device-based electrical therapy for the treatment of refractory heart failure symptoms. CCM signals are relatively high intensity, nonexcitatory signals applied during the absolute refractory period that have been shown to enhance the strength of left ventricular (LV) contraction and improve exercise tolerance and quality of life. The mechanisms of action appear to involve effects on myocardial gene expression and normalization of myocardial key-proteins. So far, more than 3500 CCM devices have been implanted worldwide. For patients with symptomatic heart failure and narrow QRS complex, CCM is together with baroreceptor activation the only additive electrical therapy which had been approved in Germany. Actually, for the first time, CCM has been referenced in the current Heart Failure Guidelines. Prognostic data with regard to mortality are currently being evaluated in case series; some of which have since been published. Approval by the US Food and Drug Administration (FDA) is expected within the next months.

Abstract
Cardiac contractility modulation (CCM) is a device-based electrical therapy for the additive treatment of chronic drug-refractory heart insufficiency. High-amplitude signals are applied during the absolute refractory period and have been shown to enhance the strength of left ventricular (LV) contraction and improve exercise tolerance and quality of life. The mechanisms of action appear to involve effects on myocardial gene expression and on normalization of key myocardial proteins. So far, more than 3500 CCM devices have been implanted worldwide. For patients with therapy refractory heart insufficiency and narrow QRS complex, CCM is together with baroreceptor activation the only additive electrical therapy which had been approved in Germany. For the first time CCM has been referenced in the current guidelines on cardiac insufficiency. Prognostic data with respect to mortality have been evaluated in case series. Ongoing randomized trials and registries will address these specific endpoints and have to a significant extent already been recently published. A Food and Drug Administration (FDA) approval is expected within the next few months.

Abstract
BACKGROUND The pathophysiology of takotsubo syndrome (TTS) is unclear so far. There is strong association of the occurrence of TTS and malignant diseases. An association between malignant diseases and myocardial infarction (MI) was found recently and ascribed to common molecular and lifestyle mechanisms. AIM To compare the outcome of patients with MI or TTS and malignant diseases in a matched cohort. METHODS Patients with TTS or with MI (n = 138 per group) were matched for age and sex and assessed retrospectively and prospectively. Occurrence of malignant diseases and clinical outcome was followed up over 4 years. RESULTS At the time of the index event, 8 (5.8%) MI patients and 17 (12.3%) TTS patients were already diagnosed with cancer. During follow up, the rate of patients who developed cancer was significantly higher in the TTS group than in the MI group (log rank P = 0.01). Mortality was higher in the TTS group, but also in the subgroup of TTS patients with cancer (log rank P < 0.05). In the multivariate analysis, male gender, renal impairment and the history of cancer was associated with an increased risk for death. CONCLUSIONS Patients with TTS have more often malignant diseases than patients with MI. Cancer patients with TTS have a worse clinical outcome. The underlying mechanism is unclear yet, but the results point at TTS being the syndrome of an extracardiac disease rather than a disease of cardiac origin. Longer and closer follow up of patients with TTS and further studies addressing the mechanism of TTS are needed.

Abstract
Patients with non-valvular atrial fibrillation (AF) and a high risk for oral anticoagulation can be treated by percutaneous implantation of left atrial appendage occlusion devices (LAAC) to reduce the risk of cardio-embolic stroke. This study evaluates whether LAAC may influence lipid metabolism, which has never been investigated before. Patients with successful LAAC were included consecutively. Venous peripheral blood samples of patients were collected immediately before (T0, baseline) and 6 months after (T1, mid-term) LAAC. A targeted metabolomics approach based on electrospray ionization liquid chromatography-mass spectrometry (ESI-LC-MS/MS) and MS/MS measurements was performed. A total of 34 lipids revealed a significant change from baseline to mid-term follow-up after successful LAAC. Subgroup analysis revealed confounding influence by gender, age, diabetes mellitus type II, body mass index, left ventricular ejection fraction, creatinine and NT-proBNP. After multivariable adjustment within logistic regression models, these 34 lipids were still significantly altered after LAAC. Successful percutaneous LAAC may affect lipid metabolism and thereby may potentially affect pro-atherogenic and cardio-toxic effects.

Abstract
AIM Takotsubo syndrome (TTS) patients have a higher mortality rate than the general population. Our study was conducted to determine the short- and long-term outcome of TTS patients associated with a significantly compromised mitral annular plane systolic excursion (MAPSE) on hospital admission. METHODS AND RESULTS Our institutional database constituted a collective of 53 patients diagnosed with TTS between 2003 and 2016. The patients were classified into two groups based on the MAPSE, with those presenting with an MAPSE <1 cm on admission categorized into one group (n = 20, 38%) and those presenting with MAPSE ≥1 cm (n = 33, 62%) categorized into another group. Preliminary results indicated that patients with an MAPSE < 1 cm had a greater risk of developing thromboembolic events. The long-term mortality was significantly higher in TTS patients with an MAPSE < 1 cm. In the multivariate Cox regression analysis, cardiogenic shock (hazard ratio 3.5; 95% confidence interval: 1.2-10.7; P = 0.02) and MAPSE < 1 cm (hazard ratio 5.1; 95% confidence interval: 1.3-19.2; P = 0.01) figured as independent predictors of the mortality. CONCLUSION Although the short-term mortality rates among TTS patients diagnosed with a reduced MAPSE on admission were as similar as without reduced MAPSE, the long-term mortality rates among TTS patients diagnosed with a reduced MAPSE on admission were significantly higher. There is an urgent need for randomized trials, which could help define uniform clinical management strategies for high-risk TTS patients.
