Current heart failure reports
-
A unique syndrome of heart failure and transient left ventricular systolic dysfunction precipitated by acute emotional or physical stress has recently emerged in the medical literature. The syndrome is referred to by several names, including stress cardiomyopathy, takotsubo cardiomyopathy, left ventricular apical ballooning syndrome, and broken heart syndrome. ⋯ As reports of this condition have increased worldwide during the past 5 years, it has become clear that stress cardiomyopathy has unique clinical features that can be readily distinguished from those of an acute myocardial infarction. This article reviews the clinical features of stress cardiomyopathy and discusses potential pathophysiologic mechanisms of this disorder.

ReviewManagement of acute pulmonary edema in the emergency department.
Noninvasive ventilation (NIV) is a safe and effective technique that can prevent side effects and complications related to endotracheal intubation. Acute cardiogenic pulmonary edema is currently the second most common indication for NIV, mainly in emergency departments. In this article we examine recent literature related to the applications of NIV in the acute setting with regard to patients with acute cardiogenic pulmonary edema. In addition, we examine the epidemiology and the pathophysiology of acute heart failure.

ReviewExercise testing with concurrent beta-blocker usage: is it useful? What do we learn?
Cardiopulmonary exercise testing (CPET) has been used for the assessment of severity of heart failure (HF), secondary to left ventricular systolic dysfunction. Initial studies determined that oxygen consumption (VO2) during exercise, as a measure of functional capacity, correlated well with the hemodynamic responses related to chronic HF. These studies led to the use of peak VO2 as a prognostic indicator in chronic HF. ⋯ These studies indicate that patients on beta-blockers have improved overall cardiovascular outcomes compared with patients not on these drugs. In addition, peak exercise VO2 still has prognostic value in beta-blocked patients; however, the thresholds for increased risk and need for transplantation have to be lower than in patients not on these drugs. There appears to be a real demand for a comprehensive survival score tool that includes the use of beta-blockade, along with CPET performance.

ReviewClinical modifiers for heart failure following myocardial infarction.
Heart failure (HF) is a clinical syndrome that occurs when the ability of the heart to meet the requirements of the body fails. Myocardial infarction (MI) is a common antecedent event that predisposes a patient to HF. Loss of cardiac function following MI occurs in the context of myocyte death and ventricular remodeling. ⋯ Use of multimodality therapy with improved clinical outcomes for HF has increased the need to specifically identify the failing heart at an earlier stage. The ability to identify heart failure early in its pathogenesis will enable finer risk stratification following MI. This article reviews various risk predictors for the development of HF following MI.

Heart failure is growing in prevalence. Despite an array of treatments targeting a complicated pathophysiology, heart failure ultimately leads to death, and thus there is a clear need to provide palliative care to persons with end-stage heart failure. Palliative care, or education and support of the patient and family and management of distressing symptoms, should be provided throughout the course of the illness. ⋯ This article summarizes recent reports about prognostication and identification of patients who are likely to die soon, and the management of fatigue, dyspnea, pain, and depression in heart failure. Palliative care or supportive care of the patient and family should be incorporated into comprehensive care throughout the course of heart failure. Data about hospice care for persons with heart failure are summarized.
