Early hemodynamic impact of SGLT2 inhibitors in overweight cardiometabolic heart failure: beyond fluid offloading to vascular adaptation- a preliminary report.

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
backgroundHeart failure (HF) is increasingly recognized as a heterogeneous cardiometabolic disorder, often in the context of overweight/obesity independently from diabetes. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) reduce HF hospitalizations and cardiovascular mortality across ejection fraction (EF) categories, yet their early hemodynamic effects in cardiometabolic HF, and with preserved ejection fraction (HFpEF) in particular, remain underexplored.
methodsA prospective, single-center study included 20 consecutive HF patients receiving SGLT2i alongside optimized therapy. Transthoracic echocardiography and non-invasive bioimpedance assessments (NICaS system) were performed at baseline and after 4 weeks.
resultsThe median patient age was 75 years [58-84], with 14 patients (70%) being overweight/obese, and only 4 patients with diabetes. The majority (65%) had HF with preserved EF (HFpEF), 25% with mildly reduced EF (HFmrEF), and 10% with reduced EF (HFrEF). At a median follow-up of 33 days [30-68], significant reductions were observed in body weight (67.65 kg [46-99.20] to 65.50 kg [46.30-97], p = 0.027) and systolic blood pressure (130 mmHg [100-150] to 116.50 mmHg [100-141], p = 0.015). Hemodynamic assessments revealed a significant decrease in total peripheral resistance index (TPRi, 3616.50 dynes·sec·cm3 [1600-5024] to 3098.50 dynes·sec·cm3 [1608-4684], p = 0.002). The left atrial volume index decreased significantly (42.84 ml/m² [27-69.40] to 41.15 ml/m² [26-62.60], p < 0.001); a significant decrease in peak tricuspid regurgitation velocity [2.52 m/Sect. (1.30-3.20]), vs. 2.21 m/Sect. (1.44-2.92), p = 0.023] and in pulmonary artery systolic pressure (PASP) [31.0 mmHg (15.0-40.0) vs. 25.50 mmHg (15.0-38.0-), p = 0.010] was observed. Patients with HFrEF or HFmrEF showed significant reduction in total body water (66.33 [51.45-74.45] vs. 58.68 [55.13-66.50]), while HFpEF patients (overweight/obese, n = 11, 79%) had a significant reduction in TPRi (3681 dynes·sec·cm3 [1600-5024] vs. 3085 dynes·sec·cm3 [1608-4684] p = 0.005).
conclusionsEarly hemodynamic responses to SGLT2i may differ across HF subtypes. In overweight patients with cardiometabolic HFpEF, our preliminary findings suggest an association with reduced vascular resistance, while in HFrEF/HFmrEF, the primary benefit appears to be volume unloading. However, the vascular effects of SGLT2i remain uncertain, and given the small sample size, these results should be interpreted as hypothesis-generating. Our findings also highlight the potential role of non-invasive hemodynamic monitoring in guiding therapy in HF.
