Short-Term Outcomes of HFrEF Patients on Guideline-Directed Medical Therapy
2026年9月15日 更新者：Omar Nasr Sayed Ahmed、Assiut University
Short-Term Outcomes of Patients With Heart Failure With Reduced Ejection Fraction (HFrEF) in View of Current Guideline-Directed Medical Therapy
This prospective cohort study aims to evaluate short-term (3-month) clinical, renal, and functional outcomes in patients with heart failure with reduced ejection fraction treated with contemporary guideline-directed medical therapy at Assiut University Hospitals.
研究概览
详细说明
Heart failure with reduced ejection fraction (HFrEF) remains a major cause of morbidity and mortality. Guideline-directed medical therapy (GDMT) with the four foundational drug classes has improved outcomes in clinical trials, but real-world short-term data from low- and middle-income settings are limited.
This observational study will include adult patients with chronic HFrEF (LVEF ≤40%) who are stable on or planned for initiation of guideline-directed medical therapy. Patients will be followed for 3 months with assessment of left ventricular ejection fraction, quality of life (KCCQ-12), renal function, and clinical events.
