Circulating dipeptidyl peptidase 3 and outcomes in acute heart failure: an analysis of the STRONG-HF and CORTAHF studies.
Trial report in ESC heart failure, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionCirculating dipeptidyl peptidase 3 (cDPP3) is implicated in cardiocirculatory failure and elevated concentrations predict poor outcomes in shock states. Its role in acute heart failure (AHF) is unexplored. We assessed the clinical relevance of cDPP3 in AHF.
methodsAnalyses were performed using two prospective AHF trials: STRONG-HF and CORTAHF. cDPP3 was measured at baseline and follow-up (day 90 in STRONG-HF; day 30 in CORTAHF). Associations with 180-day (STRONG-HF) and 90-day (CORTAHF) outcomes were evaluated according to baseline concentrations. Longitudinal changes during guideline-directed medical therapy (GDMT) optimization and predictors of elevated cDPP3 were analysed.
resultsIn STRONG-HF, 222/973 patients (23%) had cDPP3 ≥ 40 ng/mL. These patients were younger (58 ± 15 vs. 65 ± 13 years, P < .0001), more frequently female (47.7% vs. 35.8%, P = .0013) and Black (42.8% vs. 14.4%, P < .0001), with lower NT-proBNP concentrations (P < .0001). Baseline cDPP3 ≥ 40 ng/mL was not associated with 180-day outcomes. Over 90 days, cDPP3 decreased by -15% with high-intensity care and -8% with usual care (P = .078). Changes in cDPP3 were not associated with NT-proBNP reduction (continuous P = .797; ≥30% responder P = .990). In pooled multivariable analysis, MRA use was independently associated with cDPP3 ≥ 40 ng/mL (OR 3.83; 95% CI 1.47-9.96; P = .006), whereas non-Black ethnicity was associated with lower odds (OR 0.43; 95% CI 0.29-0.64; P < .0001).
conclusionIn AHF, cDPP3 was mildly elevated and was not associated with clinical outcomes or congestion relief during GDMT optimization. Elevated cDPP3 identified a distinct clinical phenotype but did not confer adverse prognosis.
