Cardio-Oncology in Cold Climates: Epidemiological Features, Bidirectional Interaction Mechanisms, and Integrated Management Strategies.
Review in Cardiovascular toxicology, 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
Cardiovascular disease (CVD) and cancer are leading causes of death worldwide, with their comorbidity posing a major public health challenge. In cold regions (latitude ≥ 45° or annual mean temperature ≤ 10 °C), this dual burden is exacerbated by unique environmental exposures and lifestyle factors. This review aims to systematically characterize the epidemiological features of CVD and cancer in cold regions, elucidate the mechanisms by which cold exposure synergistically exacerbates cancer therapy-related cardiovascular toxicity (CTR-CVT), and propose a comprehensive, cold-region-tailored management framework for the prevention, treatment, and rehabilitation of cardio-oncology comorbidity. Cold regions show significantly higher age-standardized incidence and mortality rates for both CVD and cancer compared to temperate regions. Low temperatures, high-sodium diets, and air pollution synergistically increase cardiovascular risk, while lung, colorectal, breast, and prostate cancers substantially exceed global averages. The bidirectional interaction between CVD and cancer involves multiple mechanisms. Cancer therapies induce cardiotoxicity via oxidative stress, mitochondrial dysfunction, ferroptosis, and inflammatory pathways. Conversely, CVD promotes cancer progression through chronic inflammation, neurohormonal activation, cardiac-derived factors, and exosome-mediated communication. Cold stress, acting as a synergistic toxicological factor, exacerbates comorbidity through sympathetic overactivation, amplification of oxidative and inflammatory cascades, and metabolic remodeling that disrupts drug metabolism and myocardial energy supply. In conclusion, CVD-cancer comorbidity in cold regions represents a distinct entity shaped by environmental and lifestyle factors. We propose a full-cycle, cold-region-tailored management system including cold adaptation training, dietary modification, vitamin D supplementation, integrated traditional Chinese and Western medicine, and dynamic monitoring of cardiometabolic and tumor markers. Future research should prioritize large-scale prospective studies, multi-omics approaches for sensitive biomarker identification, and region-specific interventions to reduce this dual disease burden.
