Why the study?
Does a prognostic risk score integrating CPET, echocardiographic, and clinical data improve prediction of major cardiac events in patients with chronic heart failure compared to Weber classification or NYHA functional class?
Does a prognostic risk score integrating CPET, echocardiographic, and clinical data improve prediction of major cardiac events in patients with chronic heart failure compared to Weber classification or NYHA functional class?
An integrated score combining CPET, echocardiographic, and clinical data provides better prognostic value for major cardiac events in chronic heart failure patients than traditional single-factor classifications.
This is a cohort study with a follow-up of maximum of 8 years of patients with chronic heart failure that demonstrates a simple integrated score consisting of CPET (breathing reserve, workload at maximal exercise), echocardiographic (LVEF, diastolic dysfunction), and clinical (etiology of cardiac disease) data. The generated score was a better predictor of major cardiac events (mortality or cardiac transplantation) than Weber classification (V̇o 2max classification) or NYHA functional class as single factors.
