Association between cumulative exposure to cardiometabolic index and risk of heart failure: a prospective cohort study.
Article in ESC heart failure, 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
introductionHigh cardiometabolic index (CMI) is a risk factor for heart failure (HF), but the long-term impact of cumulative CMI exposure on incident HF remains unclear. We examined the association between cumulative CMI and HF risk in a large prospective cohort.
methodsA total of 44 773 participants (mean age 53.1 ± 11.9 years; 78.6% men) from the Kailuan Study who attended three health examinations in 2006, 2008, and 2010 and were free of cardiovascular disease or cancer at baseline were included. Cumulative CMI was calculated as the weighted sum of mean CMI across time intervals and categorized into quartiles. Incident HF was identified through medical records and death registries until 31 December 2022. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals.
resultsOver a median follow-up of 12.0 years (IQR 11.7-12.3), 1018 HF events occurred. Compared with the lowest quartile, adjusted hazard ratios (95% confidence intervals) were 1.18 (0.95-1.50), 1.32 (1.05-1.65), and 1.40 (1.11-1.76) for Q2-Q4 (P for trend < 0.001). A significant interaction was observed between cumulative CMI and diabetes (P = 0.043), but not with age, sex, or hypertension. Sensitivity analyses yielded consistent results.
conclusionHigh cumulative CMI was independently associated with increased HF risk. Long-term monitoring and maintenance of an optimal CMI level may aid in early identification and prevention of HF in the general population.
