Worsening heart failure (WHF) is a severe and dynamic condition characterized by significant clinical and hemodynamic deterioration, despite optimized medical therapy. The hyperactivation of neurohormonal, adrenergic, and renin-angiotensin-aldosterone systems are key pathophysiological pathways involved in HF. While several drugs have been developed to inhibit these systems, patients still face a residual risk of adverse events. This review explores the current landscape of WHF, highlighting the complexities and factors contributing to this critical condition. Recent advances in pharmacological agents, such as guanylate cyclase stimulators and myosin activators, have shown promise. Device-based therapies, including invasive pulmonary pressure measurement and cardiac contractility modulation, have emerged as promising tools to improve quality of life and reduce hospitalizations due to HF exacerbations. The need for a multifaceted and patient-centric approach to manage WHF is emphasized, addressing the complex nature of the syndrome. Key drugs and devices, such as levosimendan, vericiguat, omecamtiv mecarbil, and CardioMEMS, are discussed, along with their mechanisms of action and clinical trial results. The review also covers the management of congestion using diuretics and innovative combinations, as well as the role of remote monitoring technologies and cardiac contractility modulation in improving patient outcomes.Worsening heart failure (WHF) is a severe and dynamic condition characterized by significant clinical and hemodynamic deterioration, despite optimized medical therapy.
