Utilization of the remote monitoring of cardiac implantable electronic devices in a diverse demographic cohort: Insights from a single-center observation.

Background: Despite its clinical benefits, patient compliance to remote monitoring (RM) of cardiac implantable electronic devices (CIEDs) varies and remains under-studied in diverse populations.

Objective: We sought to evaluate RM compliance, clinical outcomes, and identify demographic and socioeconomic factors affecting RM in a diverse urban population in New York.

Methods: This retrospective cohort study included patients enrolled in CIED RM at Montefiore Medical Center between December 2017 and May 2022.

An Overlap Presentation of Pericardial Decompression Syndrome and Stress Cardiomyopathy Following Therapeutic Pericardiocentesis.

Pericardial decompression syndrome, defined as paradoxical hypotension and pulmonary edema after pericardiocentesis, is a rare complication of pericardiocentesis. Stress cardiomyopathy, caused by excess catecholamine response resulting in left ventricular dysfunction and elevated cardiac enzymes, can overlap with pericardial decompression syndrome, and both might belong to the same spectrum of disease.

A Head-to Head Comparison of Machine Learning Algorithms for Identification of Implanted Cardiac Devices.

Application of artificial intelligence techniques in medicine has rapidly expanded in recent years. Two algorithms for identification of cardiac implantable electronic devices using chest radiography were recently developed: The PacemakerID algorithm, available as a mobile phone application (PIDa) and a web platform (PIDw) and The Pacemaker Identification with Neural Networks (PPMnn), available via web platform. In this study, we assessed the relative accuracy of these algorithms.

Electrocardiogram abnormalities in older individuals by race and ethnicity.

Background: Aging is associated with many ECG changes. ECG abnormalities are known to be more prevalent with age and differ across race and ethnicity, yet there are limited studies categorizing the ECG changes in the older population and the differences seen among racial groups. We sought to determine ECG differences associated with race and ethnicity in this ethnically diverse, elderly population.

Determination of Sensitivity and Specificity of Electrocardiography for Left Ventricular Hypertrophy in a Large, Diverse Patient Population.

Background: Electrocardiography (ECG) is poorly sensitive, but highly specific for the diagnosis of left ventricular hypertrophy. However, previous studies documenting this were small and lacked patient diversity. Furthermore, little is known about the impact of patient characteristics on the sensitivity and specificity of ECG for left ventricular hypertrophy.

Changes in atrial fibrillation admissions following daylight saving time transitions.

Background: Daylight saving time (DST) imposes a twice-yearly hour shift. The transitions to and from DST are associated with decreases in sleep quality and environmental hazards. Detrimental health effects include increased incidence of acute myocardial infarction (MI) following the springtime transition and increased ischemic stroke following both DST transitions.

A Phase I Trial of IGF-1R Inhibitor Cixutumumab and mTOR Inhibitor Temsirolimus in Metastatic Castration-resistant Prostate Cancer.

Background: Despite frequent PTEN (phosphatase and tensin homologue) loss and Akt/mammalian target of rapamycin (mTOR) signaling in prostate cancer, the disease is insensitive to single-agent mTOR inhibition. Insulin-like growth factor-1 receptor inhibition might mitigate the feedback inhibition by Torc1 inhibitors, suppressing downstream Akt activation and, thus, potentiating the antitumor activity of mTOR inhibition.

Patients And Methods: In the present phase I study, patients with metastatic castration-resistant prostate cancer received 6 mg/kg cixutumumab and 25 mg temsirolimus intravenously each week.

Relative contribution of modifiable risk factors for incident atrial fibrillation in Hispanics, African Americans and non-Hispanic Whites.

Background: Contribution of modifiable risk factors for the risk of new onset atrial fibrillation (AF) in minority populations is poorly understood. Our objective was to compare the population attributable risk (PAR) of various risk factors for incident AF between Hispanic, African American and non-Hispanic Whites.

Methods: An ECG/EMR database was interrogated for individuals free of AF for development of subsequent AF from 2000 to 2013.

Atrial Fibrillation and the Weekend Effect Regarding Cardioversion, Length of Stay, Readmission, and Mortality.

Background: The weekend effect is a phenomenon in which worse outcomes have been found to occur over the weekend. This has been investigated in the context of stroke, ST-elevation myocardial infarction, and pulmonary embolism among others. Atrial fibrillation (AF) is the most common sustained arrhythmia, and admissions for AF have been increasing.

Relation of Body Mass Index to Development of Atrial Fibrillation in Hispanics, Blacks, and Non-Hispanic Whites.

No previous studies have examined the interaction between body mass index (BMI) and race/ethnicity with the risk of atrial fibrillation (AF). We retrospectively followed 48,323 persons free of AF (43% Hispanic, 37% black, and 20% white; median age 60 years) for subsequent incident AF (ascertained from electrocardiograms). BMI categories included very severely underweight (BMI <15 kg/m), severely underweight (BMI 15.
