Background: It is uncertain whether repeated measurements of a multi-target biomarker panel may help to personalize medical heart failure (HF) therapy to improve outcome in chronic HF.

Methods: This analysis included 499 patients from the Trial of Intensified versus standard Medical therapy in Elderly patients with Congestive Heart Failure (TIME-CHF), aged ≥ 60 years, LVEF ≤ 45%, and NYHA ≥ II, who had repeated clinical visits within 19 months follow-up. The interaction between repeated measurements of biomarkers and treatment effects of loop diuretics, spironolactone, β-blockers, and renin-angiotensin system (RAS) inhibitors on risk of HF hospitalization or death was investigated in a hypothesis-generating analysis.

Aims: Neoadjuvant chemotherapy (NAC) remains an important therapeutic option for advanced oesophageal cancer (OC). Pathological tumour regression grade (TRG) may offer additional information by directing adjuvant treatment and/or follow-up but its clinical value remains unclear. We analysed the prognostic value of TRG and associated pathological factors in OC patients enrolled in the Medical Research Council (MRC) OE02 trial.

Background: Although heart failure (HF) patients are known to experience repeated hospitalizations, most studies evaluated only time to first event. N-Terminal B-type natriuretic peptide (NT-proBNP)-guided therapy has not convincingly been shown to improve HF-specific outcomes, and effects on recurrent all-cause hospitalization are uncertain. Therefore, we investigated the effect of NT-proBNP-guided therapy on recurrent events in HF with the use of a time-between-events approach in a hypothesis-generating analysis.

Aims: The aim of this study was to evaluate whether biomarkers reflecting pathophysiological pathways are different between heart failure with preserved (HFpEF) and reduced ejection fraction (HFrEF) and whether the prognostic value of biomarkers is different in HFpEF vs. HFrEF.

Methods And Results: A total of 458 HFrEF (LVEF ≤40%) and 112 HFpEF (LVEF ≥50%) patients aged ≥60 years with NYHA class ≥II from TIME-CHF were included.
