Correlation analysis of cardiac electrophysiological characteristics and cardiovascular disease progression in arrhythmia patients.
Article in American journal of translational research, 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
objectiveTo investigate a correlation between cardiac electrophysiological characteristics and cardiovascular disease (CVD) in patients with arrhythmia, and to identify indicators for predicting CVD onset.
methodsWe enrolled 100 arrhythmia patients treated at West China Hospital of Sichuan University between May 2021 and May 2023. The incidence of CVD was assessed during hospitalization and within one year post-discharge. We compared baseline characteristics, biochemical markers, and electrocardiogram parameters between patients who developed CVD and those who did not. Spearman correlation analysis was conducted to explore linear relationships between indicators and CVD incidence. Multivariate logistic regression was applied to identify associations between variables and CVD. Receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive power of individual and combined risk factors.
resultsOf the 100 patients, 31 (31%) developed CVD. The CVD group exhibited significantly higher BMI, hypertension prevalence, triglycerides (TG), high-sensitivity C-reactive protein (hs-CRP), B-type natriuretic peptide (BNP), and QT/QTc intervals compared to the non-CVD group. HDL-C levels were significantly lower in the CVD group (P < 0.05). Spearman correlation analysis revealed positive correlations between BMI, hypertension, TG, hs-CRP, BNP, QT, and QTc with CVD (r = 0.243, 0.563, 0.384, 0.514, 0.238, 0.355, 0.327, all P < 0.05). Conversely, HDL-C showed a negative correlation with CVD (r = -0.200, P < 0.05). QTc correlated significantly with BMI, hypertension, TG, and hs-CRP (r = 0.263, 0.221, 0.255, 0.200, all P < 0.05). Multi-factor logistic regression identified BMI, TG, hs-CRP, and QT/QTc intervals as significant risk factors for CVD (all P < 0.05). ROC curve analysis showed that the combined assessment of BMI, TG, hs-CRP, QT, and QTc yielded an AUC of 0.951, with sensitivity of 92.7% and specificity of 86.4%, outperforming individual tests.
conclusionElevated BMI, TG, hs-CRP, and prolonged QT/QTc intervals are significantly associated with the development of CVD in arrhythmia patients. Combined evaluation of these factors improves the accuracy of CVD risk prediction.
