Aims: The aim of the present study was to investigate the impact of aspirin on prognosis in takotsubo syndrome (TTS).
Methods And Results: Patients from the International Takotsubo (InterTAK) Registry were categorized into two groups based on aspirin prescription at discharge. A comparison of clinical outcomes between groups was performed using an adjusted analysis with propensity score (PS) stratification; results from the unadjusted analysis were also reported to note the effect of the PS adjustment.
Aims: We aimed to evaluate the frequency, clinical features, and prognostic implications of cardiac arrest (CA) in takotsubo syndrome (TTS).
Methods And Results: We reviewed the records of patients with CA and known heart rhythm from the International Takotsubo Registry. The main outcomes were 60-day and 5-year mortality.
The automated modal analysis (AMA) technique has attracted significant interest over the last few years, because it can track variations in modal parameters and has the potential to detect structural changes. In this paper, an improved density-based spatial clustering of applications with noise (DBSCAN) is introduced to clean the abnormal poles in a stabilization diagram. Moreover, the optimal system model order is also discussed to obtain more stable poles.

Firstly, the general condition and potential damage of the bridge is described. Then, the dynamic properties are extracted from 20 velocity sensors.

Objectives: This study compared prognosis between TTS and acute coronary syndrome (ACS) patients and investigated short- and long-term outcomes in TTS based on different triggers.
Background: Implantable cardioverter/defibrillator (ICD) shocks can cause myocardial injury, contributing to the progression of the underlying heart disease. The aim was to evaluate whether internal electrical cardioversion (int-CV) via the ICD or conventional external CV (ext-CV) of persistent atrial fibrillation (AF) in heart failure (HF) patients induces myocardial injury and initiates inflammation.
Methods And Results: A total of 115 HF patients with an ejection fraction between 20% and 45% were prospectively enrolled.
Background: Cardiac contractility modulation (CCM) is an electrical stimulation treatment for symptomatic heart failure (HF) patients. The procedure involves implantation of two ventricular leads for delivery of CCM impulses. The purpose of this study is to compare the efficacy and safety of CCM when the signal is delivered through one vs.

TCM is characterized by left- or biventricular apical ballooning with a clinical presentation, electrocardiographic abnormalities, and biomarker profils similar to those seen in acute myocardial infarction. Epidemiological studies have shown that TCM is more common in postmenopausal women; however exact figures are not available.

Methods: The International Takotsubo Registry, a consortium of 26 centers in Europe and the United States, was established to investigate clinical features, prognostic predictors, and outcome of takotsubo cardiomyopathy. Patients were compared with age- and sex-matched patients who had an acute coronary syndrome.
Despite the advanced therapy with statins, antithrombotics and antihypertensive agents, the medical treatment of coronary artery disease is less than optimal. Therefore, additional therapeutic anti-atherosclerotic options are desirable. This VH-IVUS study (intravascular ultrasonography with virtual histology) was performed to assess the potential anti-atherogenic effect of the PPARγ agonist pioglitazone in non-diabetic patients.

We describe a so far unreported dronedarone effect, namely a significant alteration of both the morphology and the duration of the QRS complex on the electro cardiogram in a 41-year old patient with symptomatic paroxysmal atrial fibrillation.

The study included 191 patients (85 women) aged 63 ± 10 years with a history of paroxysmal or persistent AF and a follow-up of 14 ± 5 months. The total AF recurrence rate was 67% and lone AF was significantly more often associated with AF recurrences than non-lone AF (84% vs.

Design And Setting: Retrospective multicenter case-control study. Data were collected from three cardiac units in Germany from 2006 to 2010.
Thromboembolic events are known complications of left atrial ablation therapy. We describe a complication which may also lead to systemic thromboembolism that has not been reported so far: the formation of a moving structure attached to the fossa ovalis after an attempted transseptal puncture in a 66-year old patient with symptomatic paroxysmal atrial fibrillation.

Results regarding a broader spectrum of patients and experience accumulated in clinical practice are still very scarce. Therefore, we prospectively investigated the efficacy and tolerance of dronedarone in a real life setting.

It mainly affects postmenopausal women, but no established epidemiologic data of this syndrome are available to date. Furthermore, the underlying etiologies are still largely unknown.
