Abstract
Acutely decompensated heart failure (AHF) is a severe, multifactorial syndrome with acute symptom worsening, which poses a great challenge for healthcare professionals worldwide. AHF admissions are responsible for a high percentage of morbidity, mortality, and healthcare utilization, particularly in elderly comorbid patients. The pathophysiology, clinical presentation, and treatment of AHF are presented in this review, emphasizing neurohormonal activation, hemodynamic derangements, and comorbidities such as chronic kidney disease, chronic obstructive pulmonary disease, and atrial fibrillation. Diagnostic and therapeutic approaches, including the use of beta-blockers, inotropes, and developing device-based therapies, are addressed. Controversies central to the discussion are the balancing of relief of symptoms with the possibility of adverse effects of high-dose inotropes and diuretics, the contentious continuation of beta-blockade in acute decompensation, and the emerging fluid management techniques, including ultrafiltration and the use of SGLT2 inhibitors. Also featured are promising advances in the areas of biomarker-directed therapies, regenerative medicine, and RNA-based therapies. New devices and telemedicine platforms are some of the emerging technologies underlining the shift toward precision medicine and multidisciplinary care. Despite progress being made, AHF is a heterogeneous and developing field, and further research and innovation are necessary. The intersection of pharmacological innovation, personalized medicine, and digital health offers new possibilities for the enhancement of outcomes, demanding collaboration among clinicians, researchers, and policymakers in addressing the ongoing challenges of this high-burden state.
