BackgroundHeart failure (HF) is a major cause of morbidity, mortality, and healthcare expenditure worldwide. Despite advances in medical therapy, many patients continue to experience disease progression resulting in recurrent hospitalizations and poor survival. Echocardiography provides valuable information regarding cardiac structure and function and remains the cornerstone imaging modality for diagnosis, risk stratification, and monitoring of patients with heart failure. Identification of echocardiographic predictors of disease progression allows clinicians to optimize therapeutic strategies and improve long-term outcomes.ObjectiveTo evaluate the echocardiographic parameters associated with progression of chronic heart failure and determine their relationship with adverse clinical outcomes.MethodsA hospital-based prospective observational study was conducted among 220 patients with chronic heart failure. Clinical characteristics and comprehensive transthoracic echocardiographic examinations were performed. Parameters including left ventricular ejection fraction (LVEF), left atrial volume index (LAVI), E/e′ ratio, pulmonary artery systolic pressure (PASP), tricuspid annular plane systolic excursion (TAPSE), and global longitudinal strain (GLS) were analyzed. Patients were followed for six months for hospitalization, worsening NYHA functional class, and mortality.ResultsThe mean age of patients was 63.8 ± 11.4 years, and males constituted 60.9% of the study population. Reduced LVEF (<35%), elevated E/e′ ratio (>15), enlarged LAVI (>40 mL/m²), impaired GLS (>−12%), and elevated PASP (>40 mmHg) were significantly associated with heart failure progression (p<0.05). Patients with abnormal GLS demonstrated the highest rate of hospitalization and cardiovascular mortality.ConclusionAdvanced echocardiographic parameters, particularly GLS, E/e′ ratio, LAVI, and reduced LVEF, are important predictors of heart failure progression. Routine comprehensive echocardiographic assessment may facilitate early identification of high-risk patients and improve clinical outcomes.
