Association of substance use with stroke in heart failure by community socioeconomic distress.
Article in Drug and alcohol dependence, 2025. 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
introductionSubstance use is common among individuals with heart failure (HF) and is linked to cardiotoxic effects and adverse outcomes. Given the increased vulnerability of HF patients to ischemic stroke, understanding how substance use and community distress contribute to this risk is vital for optimizing clinical prevention strategies. This study examined whether substance use increases stroke risk among HF patients and whether this association differs by community distress level.
methodsWe conducted a multicenter study using data from HF patients treated at WVU Medicine and Charleston Area Medical Center (CAMC) in West Virginia between 2017 and 2023. Multivariable logistic regression assessed the association between substance use and ischemic stroke, stratified by community distress level and adjusted for demographics and comorbidities.
resultsAmong 33,663 individuals with HF in the WVU Medicine cohort, 2651 (7.88 %) experienced a stroke. Among 8050 in the CAMC cohort, 900 (11.18 %) experienced a stroke. Overall, among both cohorts, patients with substance use disorder diagnoses had greater odds of stroke. WVU (aOR, 1.36; 95 % CI, 1.14-1.63) and CAMC (aOR, 3.50; 95 % CI, 2.85-4.55). In distressed communities, the association was stronger: WVU (aOR, 1.68; 95 % CI, 1.34-2.09) and CAMC (aOR, 3.70; 95 % CI, 3.03-4.52). In non-distressed communities, only the CAMC cohort showed a significant association (aOR, 1.80; 95 % CI, 1.63-2.09). CONCLUSIONS AND RELEVANCE: Substance use is linked to higher stroke risk among HF patients, especially in socioeconomically distressed communities. Addressing both clinical and structural factors is essential for effective stroke prevention in this population.
