Heart Failure Therapy Improves Outcomes in Adults With Congenital Heart Disease and Left Ventricular Dysfunction

Key Result

Guideline-directed medical therapy improves clinical outcomes in adults with congenital heart disease and left ventricular dysfunction.

Key Points

The study aims to explore the effects of guideline-directed medical therapy on heart failure outcomes in adults with congenital heart disease and reduced ejection fraction.
Assessment of heart failure symptoms
Evaluation of medical therapy adherence
Analysis of ejection fraction and clinical outcomes
Patients receiving guideline-directed medical therapy showed improved heart failure symptoms.
Enhanced ejection fraction was observed in treated adults compared to those not receiving therapy.
