Beyond Cardiorenal Risk Factors: The Prognostic Role of Frailty in Acute Heart Failure

Background: Frailty is highly prevalent in acute heart failure (AHF), yet whether it is more strongly associated with all-cause mortality or with non-fatal heart-failure events, and whether it adds information beyond cardiac severity, is seldom examined. Methods: In a prospective single-center registry of 530 consecuti...

Multivalvular Involvement in Acute Heart Failure: Associations with One-Year Outcomes and the Right-Heart Phenotype

Background: Valvular heart disease frequently accompanies acute heart failure (AHF), yet most studies address single valve lesions, and the prognostic weight of concurrent multivalvular involvement is less well defined. We examined the prevalence of single- and multi-valve disease and its relationship with one-year mor...

Treatment Patterns, Disease Management, and Quality of Life in Outpatients with CKD and Decreased eGFR: A Multicenter Prospective Observational Study in Greece

Background/Objectives: Chronic kidney disease (CKD) is a major cause of morbidity and mortality. Evidence on routine management and patient-reported outcomes in Greece is limited. The SPIRIT study assessed real-world treatment patterns, disease management, and quality of life (QoL) among CKD patients in Greece. Methods...

Two Phenotypes, One Prognosis: Period-Specific Mortality and Prediction of Post-Discharge Events in Acute Heart Failure

Background: The prognostic relevance of left ventricular ejection fraction (LVEF) categories in acute heart failure (AHF) remains debated. We compared the clinical phenotype of patients hospitalized for AHF with preserved (LVEF ≥ 50%) versus reduced (LVEF < 50%) ejection fraction (EF), and compared the prognostic influ...
