Advances in chemical pharmacotherapy for managing acute decompensated heart failure

INTRODUCTION: Acute decompensated heart failure (ADHF) contributes largely to the burden of heart failure and is associated with a poorer prognosis. Although numerous clinical trials evaluated the benefit of newer medications for ADHF, most of them were not successful. Areas covered: This review focusses on the updates on recent developments in chemical pharmacotherapy for the management of ADHF. A MEDLINE search for relevant review articles and original investigations on newer drugs for ADHF provided us with necessary literature. Expert opinion: Currently, popular therapies like diuretics, vasodilators, and inotropes offer symptomatic relief but do not provide survival benefit. Although multiple medications targeting novel pathways in ADHF were studied extensively, they failed to show either symptomatic or mortality benefit in available randomized trials. Improving our understanding of the complex pathophysiology of ADHF along with designing studies which include patients who are more representative of the real-world heart failure population, standardizing methods for endpoint assessment, and evaluating the role on novel biomarkers of organ dysfunction is important to improve ADHF research. Enhancing preventive strategies like improving baseline therapy in chronic heart failure patients and developing strategies for early identification of ADHF are important as our quest for innovative ADHF pharmacotherapy continues.
