Outcomes in Patients With Heart Failure Using Cocaine.
Article in The American journal of cardiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Cocaine is an established cardiovascular toxin, but the impact of cocaine use on clinical outcomes in heart failure (HF) remains unknown. Although nonselective β-blocker use in cocaine users with HF and reduced ejection fraction (HFrEF) appears to be safely tolerated, selective β-blockers have not been evaluated. This study aimed to assess whether cocaine use is associated with worse clinical outcomes in patients with HF and evaluate the safety of β-blocker prescription upon discharge in cocaine users with HFrEF. This was a single-center retrospective cohort study of patients with incident HF hospitalization at a safety-net hospital. Primary outcomes included all-cause mortality and readmissions, including HF. Cocaine users were compared with nonusers matched by age, gender, and year of index admission. In cocaine users with HFrEF, outcomes were compared according to β-blocker prescription at discharge. From 2001 to 2019, 738 cocaine users were identified and compared with 738 matched nonusers. Cocaine use was associated with increased mortality (adjusted hazard ratio [HR] 1.21; 95% confidence interval [CI] 1.00 to 1.48) and 90-day readmission (all-cause: adjusted HR 1.49; 95% CI 1.20 to 1.85; HF: adjusted HR 1.49; 95% CI 1.10 to 2.01), persisting at 1 year. In cocaine users who were prescribed metoprolol, carvedilol, or no β-blocker at discharge, the rates of 1-year mortality and 30-day readmission were similar. In conclusion, cocaine use is associated with increased all-cause mortality, HF readmission, and all-cause readmission. Both nonselective and selective β-blocker may be safe in managing patients with HFrEF and cocaine use.
