RESUMEN

Acute heart failure (AHF) is one of the most important causes of mortality, morbidity and rising healthcare costs. Despite this, there has been minimal advancement in the management of AHF and the treatment continues to focus on symptomatic improvement using vasodilators, diuretics and inotropes, none of which have shown any mortality benefits. Though originally thought of as a reproductive hormone, relaxin is now recognized as a potent vasodilator that modulates systemic and renal vascular tone, resulting in pre- and after-load reduction and a decrease in cardiac workload. A single intravenous infusion of relaxin over 48 hours has been shown to provide significant dyspnea relief among AHF patients, with an ongoing study to evaluate its potential for mortality benefit. This article provides an insight into the pharmacology of this novel therapy for AHF with an eye towards future clinical applications.

RESUMEN

With rising patient volumes and increasingly complex cases, the specialty of emergency medicine faces a growing array of challenges. Efforts have been made to improve patient throughput, yet little attention has been directed to the increasing amount of primary care delivered in emergency departments (EDs) for chronic disease states such as hypertension and diabetes. Management of chronic medical conditions is traditionally seen as beyond the purview of the ED and emergency physicians tend to defer critical aspects of related patient care to other components of the healthcare continuum. As a result, vulnerable patients are often forced to navigate exceedingly complex and fragmented systems of care with little guidance, which often leads to inadequate treatment and exposure to increased risk for development of potentially avoidable complications. As evidenced by our experience with hypertension in an under resourced community, there is a crucial need for emergency physicians to espouse their role as providers of healthcare across the acuity spectrum and lead the way in defining regionally relevant solutions to better manage patients with chronic medical problems.
