From End-of-Life Care to Improved Quality of Life and Better Prognosis by Using Vericiguat: A Case Report From Costa Rica

Abstract

In this case report, we present the evolution of a heart failure with reduced ejection fraction (HFrEF) patient who was set to receive end-of-life care but demonstrated improvement following treatment with vericiguat in combination with foundational therapy. Vericiguat is a novel soluble guanylate cyclase stimulant that has been proven helpful for treating decompensated heart failure with HFrEF, decreasing hospitalization rates and mortality of cardiovascular causes. This medication is currently indicated in patients who require IV diuretics administration or hospitalization due to decompensated heart failure. This is a case study of a 62-year-old woman with dilated heart failure and reduced left ventricular ejection fraction (LVEF), who was a wheelchair user due to severe cardiovascular symptoms and various comorbidities, who was referred to our heart failure program for treatment. Despite previous treatment, the patient experienced persistent cardiovascular symptoms and required palliative care. After optimizing the foundational therapy, the patient's condition improved but continued to require hospitalization. Vericiguat was initiated as an add-on. After six months, the patient's LVEF improved by 9%, and she is now asymptomatic with a considerable decrease in pro-B-type natriuretic peptide levels and is wheelchair independent due to enhance exercise resistance. However, the echocardiogram revealed a progression in the dysfunction of both the mitral and aortic valves. The patient's renal function and quality of life scores also changed over time. Vericiguat therapy, as an adjunct to foundational therapy, improved exercise tolerance and symptom relief. However, further investigation is necessary to assess the effects of vericiguat on renal function and disease progression in individuals with HFrEF.
