Association Between Chronic Obstructive Pulmonary Disease Severity and Heart Failure in a Tertiary Care Cohort.
Article in Cureus, 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
backgroundChronic obstructive pulmonary disease (COPD) is a progressive respiratory disorder that often coexists with cardiovascular comorbidities, particularly heart failure (HF).
objectiveTo evaluate the association between the severity of COPD and the prevalence of HF in patients treated at a tertiary care hospital. METHODOLOGY: This prospective cross-sectional analytical study was conducted at Dr. Faisal Masood Teaching Hospital, Sargodha, Pakistan, from July 2024 to July 2025 on 225 patients with confirmed COPD. The severity of COPD was classified according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. Patients were evaluated for HF through clinical examination, echocardiographic assessment, and biomarker analysis, where available.
resultsThe mean age of participants was 61.4 ± 9.7 years, with a male predominance (69.3%). Overall, 72 patients (32.0%) were diagnosed with HF. The prevalence of HF increased progressively with COPD severity: 5.9% in GOLD I, 17.7% in GOLD II, 42.7% in GOLD III, and 70.0% in GOLD IV (p < 0.001). On multivariate analysis, severe-to-very-severe COPD (OR = 5.4, 95% CI: 2.8-10.5, p < 0.001), hypertension (OR = 2.7, 95% CI: 1.4-5.3, p = 0.002), and age ≥ 60 years (OR = 1.9, 95% CI: 1.1-3.8, p = 0.04) were independent predictors of HF.
conclusionIt is concluded that increasing COPD severity is significantly associated with a higher incidence of HF. Patients with advanced COPD are at greater risk of developing cardiac dysfunction due to overlapping pathophysiological mechanisms and shared risk factors.
