Ambulatory Hemodynamic Monitoring Reduces Heart Failure Hospitalizations In "Real-World" Clinical Practice, Akshay S. Desai, Arvind Bhimaraj, Rita Jermyn, Jamie M. Pelzel

Articles

BACKGROUND:

In the CHAMPION (CardioMEMS Heart Sensor Allows Monitoring of Pressure to Improve Outcomes in New York Heart Association [NYHA] Functional Class III Heart Failure Patients) trial, heart failure hospitalization (HFH) rates were lower in patients managed with guidance from an implantable pulmonary artery pressure sensor compared with usual care.

OBJECTIVES:

This study examined the effectiveness of ambulatory hemodynamic monitoring in reducing HFH outside of the clinical trial setting.

METHODS:

We conducted a retrospective cohort study using U.S. Medicare claims data from patients undergoing pulmonary artery pressure sensor implantation between June 1, 2014, and December 31, 2015. Rates of HFH …

Relationship Of Paroxysmal Atrial Tachyarrhythmias To Volume Overload, Rajat Jhanjee Md, Grant A. Templeton Md, Srinivasan Sattiraju Md, John Nguyen Md, Simon Milstein Md, Laura Van Heel, Keith G. Lurie Md, David Benditt Md

Articles

BACKGROUND:

Clinical experience suggests that atrial tachyarrhythmias (ATs) are a frequent comorbidity in heart failure patients with left ventricular systolic dysfunction and that volume overload may increase AT susceptibility. However, substantiating this apparent relationship in free-living patients is difficult. Recently, certain implantable cardioverter-defibrillators provide, by measuring transpulmonary electric bioimpedance, an index of intrathoracic fluid status (OptiVol index [OI]). The goal of this study was to determine whether periods of greater intrathoracic fluid congestion (as detected by OI) correspond with increased AT event frequency.

METHODS AND RESULTS:

This analysis retrospectively assessed the relation between AT events and OI estimate of volume …

Reduced Atrial Tachyarrhythmia Susceptibility After Upgrade Of Conventional Implanted Pulse Generator To Cardiac Resynchronization Therapy In Patients With Heart Failure, Demetris Yannopoulos, Keith Lurie Md, Scott Sakaguchi, Simon Milstein Md

Articles

OBJECTIVES:

We sought to identify the impact of cardiac resynchronization therapy (CRT) on atrial tachyarrhythmia (AT) susceptibility in patients with left ventricular (LV) systolic dysfunction in whom worsening heart failure (HF) resulted in upgrade from conventional dual-chamber pulse generator to cardiac resynchronization therapy-defibrillator (CRT-D).

BACKGROUND:

Cardiac resynchronization therapy with a defibrillator improves survival rates and symptoms in patients with LV systolic dysfunction but little is known about its effects on AT incidence in the same patient population.

METHODS:

Twenty-eight consecutive HF patients who underwent device upgrade to CRT-D were included. Patients had > or =2 device interrogations in the 1 year …
