Impact of COVID-19 on Heart Failure Hospitalizations.

The Novel Coronavirus Disease 2019 (COVID-19) pandemic has transformed individual lives and societal framework on a global scale, and in no other sector is this more evident than healthcare. Herein, we aim to describe the impact of the current COVID-19 pandemic and its associated restrictions on heart failure (HF) admissions. In this retrospective cohort study, we obtained administrative data for patients with a primary discharge diagnosis of HF (identified by ICD-10 code) with discharge dates ranging from January 2019 to November 2020.

Hospitalization and Post-hospitalization Outcomes Among Teaching Internal Medicine, Employed Hospitalist, and Locum Tenens Hospitalist Services in a Tertiary Center: a Prospective Cohort Study.

Background: There are no prospective studies comparing hospitalization and post-hospitalization outcomes between teaching internal medicine services and non-teaching hospitalists, and no prospective studies comparing these outcomes between locum and employed hospitalists.

Objective: To compare the length of stay, hospital costs readmission rate, and mortality rate in patients treated by teaching internal medicine services vs. hospitalists and among patients treated by locum vs.

Predictors of reduced cardiac index in patients with acute submassive pulmonary embolism.

Objectives: Determine the baseline clinical, laboratory, and echocardiographic values that predict reduced cardiac index (CI) among subjects with acute submassive pulmonary embolism (PE).

Background: Submassive PE represents a large portion of acute PE population and there is controversy regarding optimal treatment strategies for these patients. There is significant heterogeneity within the submassive PE population and further refinement of risk stratification may aid clinical decision-making.

Peritoneal Dialysis Zoonotic Bacterial Peritonitis with .

We present the first reported case of peritoneal dialysis-associated peritonitis caused by , an organism that had been misclassified as . in the past. .

Prognostic Value of Computed Tomography Versus Echocardiography Derived Right to Left Ventricular Diameter Ratio in Acute Pulmonary Embolism.

Background: Computed Tomography (CT) Pulmonary Angiography is the most commonly used diagnostic study for acute pulmonary embolism (PE). Echocardiogram (ECHO) is also used for risk stratification in acute PE, however the diagnostic performance of CT versus ECHO for risk stratification remains unclear.

Methods: CT and ECHO right ventricle (RV) and left ventricle (LV) diameters were measured in a retrospective cohort of patients with acute PE.

Bupropion in the treatment of postural orthostatic tachycardia syndrome (POTS): a single-center experience.

Postural orthostatic tachycardia syndrome (POTS) is estimated to impact millions of people each year. However, there is no established gold standard for its treatment. Bupropion is a norepinephrine and a dopamine reuptake inhibitor and has been implicated as a potential treatment for POTS.

Safety and Efficacy of Leadless Pacemakers: A New Era of Pacing.

Leadless pacemakers are evolving as a new technologic alternative to conventional transvenous pacemakers, though potential short-term and long-term complications have been recognized. The two currently available right ventricular leadless pacing systems are the Nanostim™ Leadless Cardiac Pacemaker (Abbott Laboratories, Chicago, IL, USA) and the Micra™ Transcatheter Pacing System (Medtronic, Minneapolis, MN, USA). This review aims to highlight the safety and efficacy of leadless pacemakers using these two devices as exemplars.

Clinical and histopathological effects of heart failure drug therapy in advanced heart failure patients on chronic mechanical circulatory support.

Aims: Adjuvant heart failure (HF) drug therapy in patients undergoing chronic mechanical circulatory support (MCS) is often used in conjunction with a continuous-flow left ventricular assist device (LVAD), but its potential impact is not well defined. The objective of the present study was to examine the effects of conventional HF drug therapy on myocardial structure and function, peripheral organ function and the incidence of adverse events in the setting of MCS.

Methods And Results: Patients with chronic HF requiring LVAD support were prospectively enrolled.

Favorable Effects on Pulmonary Vascular Hemodynamics with Continuous-Flow Left Ventricular Assist Devices Are Sustained 5 Years After Heart Transplantation.

It is unclear whether pulmonary hemodynamics improvement with left ventricle unloading with left ventricular assist devices (LVADs) is sustained long term after heart transplant (HT). We sought to assess the effects on pulmonary vascular hemodynamics during continuous-flow (CF-LVAD) and pulsatile flow (PF-LVAD) support up to 5 years after HT. Invasive hemodynamics were evaluated before LVAD, before HT, and at 3 months, 1, and 3-5 years posttransplant.

Myocardial Structural and Functional Response After Long-Term Mechanical Unloading With Continuous Flow Left Ventricular Assist Device: Axial Versus Centrifugal Flow.

Objectives: The aim of this study was to assess the impact of continuous-flow left ventricular assist device (LVAD) type-axial flow (AX) versus centrifugal flow (CR)-on myocardial structural and functional response following mechanical unloading.

Background: The use of continuous-flow LVADs is increasing steadily as a therapeutic option for patients with end-stage heart failure who are not responsive to medical therapy. Whether the type of mechanical unloading influences the myocardial response is yet to be determined.
