Background: Heart failure with mildly-reduced ejection fraction (HFmrEF) of 40-49% is an under-recognized type of heart failure. The prognosis and predictors of outcomes of stable mildly-reduced ejection fraction (EF) of one year are unclear. Methods: This is a retrospective study. Included patients had stable left ventricular ejection fraction...

Background Heart failure with mid-range ejection fraction (HFmrEF) of 40-49% is an under-recognized class of CHF. The impact of NYHA functional classification on clinical outcomes in patients with HFmrEF with stable ejection fraction of 1 year is unclear. Methods We screened 7668 echo studies to identify patients with stable HFmrEF. Follow up was...

Background Heart failure with reduced ejection fraction (HFrEF) of < 40% is a well-studied class of CHF. Nevertheless, in patients with HFrEF and stable ejection fraction (EF) of 1 year, the effect of EF reduction degree on clinical outcomes is unclear. Methods We screened 7668 echo studies to identify patients with stable HFrEF. Follow up was for...

Techniques in vascular and interventional radiology are adapted to the ever-evolving clinical challenges that interventional operators face. In the case of rare diseases, supporting literature that guides an operator's plan for intervention is limited. As a result, published case reports and series can be utilized to direct future intervention and...

Infections of the lumbar spine can have serious sequelae, including neurological deficits, paralysis, and death. Prolonged infection can result in fracture of the vertebrae, local abscesses, and infiltration and compression of local vascular structures. In cases with significant instability or neurological compromise, a common treatment approach is...

Background Heart failure with mid-range ejection fraction (HFmrEF) of 40-49% is an under-recognized class of CHF. The impact of heart failure etiology in patients with HFmrEF and stable ejection fraction (EF) of one year is unclear. Objectives We hypothesized that patients with ischemic cardiomyopathy (ICMP) and stable mid-range EF (mrEF) and pati...

Background Heart failure with mid-range ejection fraction (HFmrEF) of 40-49% is an under-recognized class of CHF. Prognosis of HFmrEF in comparison to HFrEF and HFpEF with stable EF of 1 year is unclear. Objectives We hypothesized that HFmrEF patients with stable EF of 1 year have different mortality and morbidity prognosis compared to HFrEF and H...

Background Heart failure with mid-range ejection fraction (HFmrEF) of 40-49% is an under-recognized class of CHF. In patients with HFmrEF and stable ejection fraction (EF) of 1 year, the effect of CKD on mortality outcomes is unclear. Objectives We sought to determine if the presence of CKD can result in a higher mortality rate in patients with HF...

Background Heart failure with reduced ejection fraction (HFrEF) of < 40% is a well-studied class of CHF. Nevertheless, in patients with HFrEF and stable ejection fraction (EF) of 1 year, the impact of CKD on prognosis is unclear. Objectives We hypothesized that the presence of CKD can result in a worse prognosis in patients with HFrEF and stable E...

Background Heart failure with mid-range ejection fraction (HFmrEF) of 40-49% is an under-recognized class of CHF. The impact of gender differences on prognosis in patients with HFmrEF with stable ejection fraction (EF) over one year is unclear. Objectives We sought to determine if male and female patients with stable mid-range EF have different mo...

Stroke is the fifth leading cause of death in the United States and is one of the leading causes of patient disability. Treatments for intracranial intravascular damage as a result of stroke have evolved extensively over recent decades, as management has become increasingly innovative. Various prospective studies and years of data have refined the...

This work investigates the suitability of transmission-line resistance compression networks (TLRCNs) for energy recovery applications in wideband microwave outphasing transmitters. In order to successfully recover microwave power without introducing distortion in the outphasing transmitter, the energy recovery network must remain both efficient and...
