Temporal and demographic trends in cardiogenic shock and chronic ischemic heart disease-related mortality among U.S adults aged 45 years and older: a 25 year nationwide analysis with ARIMA forecasting.
Article in BMC cardiovascular disorders, 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
backgroundCardiogenic shock (CS) and chronic ischemic heart disease (CIHD) remain major contributors to cardiovascular mortality in the United States. Although mortality related to ischemic disease declined in the early 2000s, recent trends suggest a resurgence.
methodsThis population-based study utilized the Centers for Disease Control and Prevention’s Wide-Ranging OnLine Data for Epidemiologic Research (CDC WONDER) database from 1999 to 2023. Deaths were identified using ICD-10 codes R57.0 (CS) and I25 (CIHD). Adults aged ≥ 45 years were included. Crude mortality rates (CMRs) and age-adjusted mortality rates (AAMRs) were calculated, with temporal changes assessed using Joinpoint regression to estimate Annual Percent Change (APC) and Average Annual Percent Change (AAPC).
resultsBetween 1999 and 2023, deaths attributed to CS and CIHD accounted for 78,903 cases among adults ≥ 45 years. Overall AAMR ranged from 35.88 per million in 1999 to 37.44 per million in 2023, with a downward trend from 1999 to 2012 followed by an upward trend thereafter. Males (51,080 deaths) exhibited rising mortality (AAPC: +0.50, p < 0.001), while females (27,823 deaths) showed a decline (AAPC: − 0.91, p < 0.0004). Non-Hispanic Black adults demonstrated the steepest increase (AAPC: +1.85, p < 0.001). The burden was greatest in adults ≥ 65 years, but the 45–64 group showed the fastest rise (AAPC: +1.67, p < 0.001).
conclusionMortality from cardiogenic shock and chronic ischemic heart disease among U.S. adults ≥ 45 years declined initially but reversed after 2012. Rising mortality in middle-aged adults, persistent racial disparities, and geographic inequities highlight urgent gaps in prevention and acute care.
