Intermittent Short Atrioventricular Delay in a Dual Chamber Pacemaker During Acute Pulmonary Edema.

We present the case of an 80-year-old female with acute pulmonary edema and a dual chamber pacemaker with intermittent short AV delays in the surface ECG after blocked premature atrial contractions (PACs). The behavior was consistent with the programmed Window of Atrial Rate Acceleration Detection (WARAD) and did not require further parameter modifications. As most cardiologists and emergency department physicians are not familiar with brand-specific algorithms, we believe that this case report will make these noncompetitive atrial pacing algorithms more accessible to non-cardiologists.

Impact of mechanical circulatory support on outcomes in Takotsubo syndrome complicated by cardiogenic shock: Insights from the RETAKO registry.

Background: Cardiogenic shock (CS) complicates Takotsubo syndrome (TTS), significantly affecting patient outcomes. Since avoiding catecholamines, particularly inotropic agents, is recommended in TTS, temporary mechanical circulatory support (MCS) shows promise as a bridge to recovery. However, there is no prospective data on its use in TTS.

Recovery of Left Ventricular Function and Long-Term Outcomes in Patients With Takotsubo Syndrome.

Background: Takotsubo syndrome (TTS) is a form of transient left ventricular (LV) dysfunction that usually resolves within days to weeks.

Objectives: We aimed to assess the predictors and prognostic impact of time-to-LV recovery after TTS.

Methods: Prospective serial imaging data from the nationwide, multicenter RETAKO (REgistry on TAKOtsubo Syndrome) were comprehensively reviewed to assess the timing of LV recovery.

Specific locations of myocardial inflammation and fibrosis are associated with higher risk of events in cardiac sarcoidosis.

Background: F-Fluorodeoxyglucose (F-FDG) positron emission tomography (PET)/magnetic resonance (MR) can identify inflammation and fibrosis, which are high-risk features in cardiac sarcoidosis.

Objective: The purpose of this study was to evaluate whether the involvement of certain myocardial segments is associated with higher risk compared to others.

Methods: One hundred twenty-four patients with suspected clinical sarcoidosis underwent F-FDG-PET/MR.

Left ventricular outflow tract obstruction in Takotsubo syndrome with cardiogenic shock: prognosis and treatment.

Background: Patients with Takotsubo syndrome (TTS) who develop cardiogenic shock may present with left ventricular outflow tract obstruction (LVOTO). The prognosis and treatment of this population have not been defined in previous studies. The aim of this study is to describe the clinical presentation, management, evolution and prognosis of a subgroup of patients with TTS and cardiogenic shock according to whether they present with LVOTO or not.

Renal impairment and outcome in Takotsubo syndrome: Insights from a national multicentric cohort.

Introduction: Data on the association between kidney function and Takotsubo syndrome (TTS) outcomes are scarce and conflictive.

Objective: To assess the impact of chronic kidney disease (CKD) and acute renal failure (ARF) in patients with TTS.

Material And Methods: Patients from the prospective nation-wide (RETAKO) registry were included and divided into quartiles of maximum creatinine (Cr) level during hospitalization.

Pediatric takotsubo cardiomyopathy: A review and insights from a National Multicentric Registry.

Takotsubo syndrome (TTS) in the pediatric population is an infrequent but relevant cause of morbidity and mortality, with limited studies addressing its clinical course and prognosis. We aimed to analyze the clinical features and prognosis of pediatric TTS in a nation-wide multicenter registry and considering the published literature. We included a total of 54 patients from 4 different hospitals in Spain, as well as pediatric TTS patients from the published literature.

Prognostic Utility of Society for Cardiovascular Angiography and Interventions Shock Stage Approach for Classifying Cardiogenic Shock Severity in Takotsubo Syndrome.

Background: Cardiogenic shock (CS) is a significant complication of Takotsubo syndrome (TTS), contributing to heightened mortality and morbidity. Despite this, the Society for Cardiovascular Angiography and Interventions (SCAI) staging system for CS severity lacks validation in patients with TTS and CS. This study aimed to characterize a patient cohort with TTS using the SCAI staging system and assess its utility in cases of TTS complicated by CS.

Cardiac Insulin Resistance in Subjects With Metabolic Syndrome Traits and Early Subclinical Atherosclerosis.

Objective: Experimental evidence suggests that metabolic syndrome (MetS) is associated with changes in cardiac metabolism. Whether this association occurs in humans is unknown.

Research Design And Methods: 821 asymptomatic individuals from the Progression of Early Subclinical Atherosclerosis (PESA) study (50.

Changes in visual function and retinal structure in the progression of Alzheimer's disease.

Background: Alzheimer's Disease (AD) can cause degeneration in the retina and optic nerve either directly, as a result of amyloid beta deposits, or secondarily, as a result of the degradation of the visual cortex. These effects raise the possibility that tracking ophthalmologic changes in the retina can be used to assess neurodegeneration in AD. This study aimed to detect retinal changes and associated functional changes in three groups of patients consisting of AD patients with mild disease, AD patients with moderate disease and healthy controls by using non-invasive psychophysical ophthalmological tests and optical coherence tomography (OCT).
