Pharmacological treatment of patients with chronic heart failure. Subanalysis of an Ecuadorian registry.

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
Introduction: Introduction. In Ecuador, there is limited data on the treatment of patients with heart failure (HF). Objective: This study aimed to determine the rate of use of prognosis-modifying drugs and their association with prognosis. Materials and methods: A retrospective observational study was conducted on patients with chronic HF included in the "Los Ceibos" registry between January 2017 and December 2022. Patients were followed for a median of 2.28 years (interquartile range [IQR]: 1.25-3.49). Results: A total of 711 patients diagnosed with HF were included. Among them, 82.7% (n=588) received angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), or angiotensin receptor-neprilysin inhibitors (ARNIs); 82.3% (n=585) received beta-blockers (BBs); and 51.3% (n=365) were treated with mineralocorticoid receptor antagonists (MRAs). Among patients with HFrEF, those receiving triple therapy (ACEI/ARB/ARNI + BB + MRA) had lower all-cause mortality compared to other groups (38.8%, log-rank p=0.014). In patients with Heart Failure with preserved Ejection Fraction (HFpEF), no mortality differences were observed according to the number of medications used (log-rank p=0.720). MRA use was not associated with a prognostic benefit in HFpEF (p>0.05). Patients receiving triple therapy with ARNI + BB + MRA had better survival during follow-up compared to any other drug combination (log-rank p=0.027). Conclusions: A high rate of ACEI/ARB/ARNI and BB use was observed. The use of triple therapy, particularly the combination of ARNI + BB + MRA, was associated with improved prognosis in patients with HFrEF over a four-year follow-up period. No prognostic benefit of MRA use was observed in patients with HFpEF.
