Wearable Technology in Cardiology: Advancements, Applications, and Future Prospects.

As the use of wearable devices continues to expand, their integration into various aspects of healthcare becomes increasingly prevalent. Indeed, significant advancements have been made in the field of cardiology through the application of wearable technology to monitor heart rate, rhythm, and other biological signals. This review examines the various applications of wearable technology in cardiology, with the goal of improving patient care.

Discordant Diagnostics: A Case Series of iFR and FFR Discrepancies.

Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) are 2 methods used to detect hemodynamically significant lesions and guide revascularization. Discrepancies between FFR and iFR values can complicate revascularization decisions. We present a series of 6 cases with discrepant FFR and iFR results.

Safety and Efficacy of Radial Artery Access for Peripheral Vascular Intervention: A Single-Center Experience.

Radial artery (RA) access has been increasingly utilized for coronary procedures because of lower rates of access-site complications and improved patient satisfaction. However, limited data are available for RA access for peripheral vascular intervention (PVI). We performed a retrospective review of 143 patients who underwent PVI through RA access from February 2020 to September 2022 at a single institution.

Venous thromboembolism in COVID-19 patients and prediction model: a multicenter cohort study.

Background: Patients with COVID-19 infection are commonly reported to have an increased risk of venous thrombosis. The choice of anti-thrombotic agents and doses are currently being studied in randomized controlled trials and retrospective studies. There exists a need for individualized risk stratification of venous thromboembolism (VTE) to assist clinicians in decision-making on anticoagulation.

Data of atrial arrhythmias in hospitalized COVID-19 and influenza patients.

Atrial arrhythmias (AA) are common in hospitalized COVID-19 patients with limited data on their association with COVID-19 infection, clinical and imaging outcomes. In the related research article using retrospective research data from one quaternary care and five community hospitals, patients aged 18 years and above with positive SARS-CoV-2 polymerase chain reaction test were included. 6927 patients met the inclusion criteria.

Incidence, Mortality, and Imaging Outcomes of Atrial Arrhythmias in COVID-19.

Atrial arrhythmias (AAs) are common in hospitalized patients with COVID-19; however, it remains uncertain if AAs are a poor prognostic factor in SARS-CoV-2 infection. In this retrospective cohort study from 2014 to 2021, we report in-hospital mortality in patients with new-onset AA and history of AA. The incidence of new-onset congestive heart failure (CHF), hospital length of stay and readmission rate, intensive care unit admission, arterial and venous thromboembolism, and imaging outcomes were also analyzed.

Meta-analysis Comparing Transradial Versus Transfemoral Secondary Access in Transcatheter Aortic Valve Implantation.

Up to a quarter of vascular complications during transcatheter aortic valve implantation (TAVI) result from secondary access via the femoral artery (FA). The radial artery (RA) is increasingly used as an alternative to the FA for secondary access in TAVI. Limited data exist on the outcomes of RA secondary access versus FA secondary access.

Diagnostic Yield of Rescreening Adults for Pulmonary Arteriovenous Malformations.

Purpose: To determine the yield of rescreening adult hereditary hemorrhagic telangiectasia (HHT) patients with initial negative screening CT for pulmonary arteriovenous malformations (PAVMs).

Materials And Methods: Patients with a definite diagnosis of HHT were identified in the University of Toronto, Université de Montréal, and Mayo Clinic HHT databases. Inclusion criteria were: (i) definite diagnosis of HHT; (ii) initial negative PAVM screening based on bubble echocardiography and/or chest CT; and (iii) minimum 2-year imaging follow-up.

Left Ventricular Thrombus After Acute Decompensated Heart Failure in the Setting of Ischemic Cardiomyopathy.

A 70-year-old male with a medical history significant for long-standing ischemic cardiomyopathy (ICM) and heart failure with reduced ejection fraction (HFrEF) was admitted to the hospital with shortness of breath (SOB) five days after an acute heart failure (HF) exacerbation. He had non-radiating chest pressure now at rest, but without evidence of an acute coronary syndrome (ACS). Diagnostic work-up on readmission included a transthoracic echocardiogram (TTE), which revealed worsening left ventricular (LV) systolic dysfunction with new wall motion abnormalities and an incidental echo density in the LV apex, suggestive of an LV thrombus.

Clinical Outcomes of Weight-Based Norepinephrine Dosing in Underweight and Morbidly Obese Patients: A Propensity-Matched Analysis.

Background: Weight-based dosing strategy for norepinephrine in septic shock patients with extremes of body mass index has been lesser studied.

Methods: This historical study of adult septic shock patients was conducted from January 1, 2010, to December 31, 2015, at all intensive care units (ICUs) in Mayo Clinic, Rochester. Patients with documented body mass index were classified into underweight (body mass index <18.

Impact of Age on Outcomes in Hospitalized Patients with Hereditary Hemorrhagic Telangiectasia.

Background: There is little published literature regarding the impact of age on outcomes amongst hospitalized HHT (hereditary hemorrhagic telangiectasia) patients.

Methods: The Nationwide Inpatient Sample (NIS) was used to obtain data on all hospital discharges occurring in HHT patients from 2000 to 2012. The association between admission age and HHT-related complications and outcomes were studied.

Intravenous Bevacizumab for Refractory Hereditary Hemorrhagic Telangiectasia-Related Epistaxis and Gastrointestinal Bleeding.

Objective: To present a multiyear clinical experience with intravenous bevacizumab for the management of severe gastrointestinal bleeding and/or epistaxis in patients with hereditary hemorrhagic telangiectasia (HHT).

Patients And Methods: All patients treated with intravenous bevacizumab for severe hereditary hemorrhagic telangiectasia-related bleeding from June 1, 2013, through January 31, 2017, were included in this report. Severity of epistaxis (determined using the Epistaxis Severity Score questionnaire); hemoglobin, iron, and ferritin levels; and quality of life data were collected serially in all patients.

Saddle vs Nonsaddle Pulmonary Embolism: Clinical Presentation, Hemodynamics, Management, and Outcomes.

Objective: To understand the clinical significance, hemodynamic presentation, management, and outcomes of patients presenting with saddle pulmonary embolism (PE).

Methods: All patients with saddle PE diagnosed at Mayo Clinic in Rochester, Minnesota, from January 1, 1999, through December 31, 2014, were included in this study. These patients were age and simplified Pulmonary Embolism Severity Index (sPESI) matched (1:1) to a nonsaddle PE cohort.

Multifocal micronodular pneumocyte hyperplasia (MMPH) in a patient with tuberous sclerosis-evidence for long term stability.

Multifocal micronodular pneumocyte hyperplasia (MMPH) is rare entity seen mostly in patients with the tuberous sclerosis complex (TSC). We present the case of a 50 year old woman with TSC (confirmed mutation) found to have multiple ground glass opacities with an upper lobe predominance on a screening chest CT. No abnormalities were detected in other viscera.

Occupational asthma: diagnostic challenges and management dilemmas.

Purpose Of Review: Work-related asthma encompasses both sensitizer-induced and irritant-induced occupational asthma as well as work-exacerbated asthma. This review summarizes current diagnostic and management strategies for occupational asthma.

Recent Findings: Occupational asthma is the most common occupational lung disease in the industrialized world.

Effect of Center Volume on Outcomes in Hospitalized Patients With Hereditary Hemorrhagic Telangiectasia.

Objective: To determine whether hospitalized patients with hereditary hemorrhagic telangiectasia (HHT) had better outcomes at high-volume treatment centers (HVCs).

Patients And Methods: The Nationwide Inpatient Sample (2000-2011) was used to identify HHT-related hospitalizations. Hospitals were classified based on quartiles of annual HHT discharge volume.
