Association Between Intravenous Magnesium Sulfate and All-Cause Mortality in Patients With Acute Heart Failure: A Propensity Score-Matched Cohort Study in MIMIC-IV.
Article in Reviews in cardiovascular medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: Magnesium deficiency represents a prevalent electrolyte imbalance that notably heightens the risk of adverse cardiovascular incidents among individuals with heart failure. Research indicates that magnesium supplementation can diminish the frequency of negative events linked to hypomagnesemia in heart failure patients, while also enhancing the outcomes for critically ill individuals. Nevertheless, there remains a scarcity of studies investigating the effects of intravenous magnesium supplementation on mortality risk in those suffering from acute heart failure. This study aimed to explore the relationship between the administration of intravenous magnesium sulfate and the overall mortality risk in patients with acute heart failure who are admitted to intensive care units. Methods: This retrospective cohort study employed the Medical Information Mart for Intensive Care IV (MIMIC-IV) database (version 3.1), which encompasses the baseline clinical data of 10,031 patients diagnosed with acute heart failure. Propensity score matching and multivariate Cox regression analysis were utilized to assess the effects of intravenous magnesium sulfate on 28-day all-cause mortality. The evaluation of unmeasured confounding variables was undertaken through E-value calculations, while subgroup analyses were performed to ascertain the robustness of the results. Results: A total of 10,031 patients participated in the study, with 6240 belonging to the propensity-score matched group, which included 3120 subjects who received intravenous magnesium sulfate and 3120 who did not. The entire cohort consisted of 10,031 individuals, whereas the matched cohort specifically comprised 6240 patients. Within the matched group, the rates of 28-day all-cause mortality were observed to be 13.2% (413/3120) for those administered intravenous magnesium sulfate, compared to 15.8% (493/3120) for the control group. Administration of intravenous magnesium sulfate correlated with a significantly reduced risk of 28-day all-cause mortality (hazard ratio (HR), 0.81; 95% confidence interval (CI), 0.71-0.93; Conclusions: Intravenous magnesium sulfate appears to decrease all-cause mortality in patients with acute heart failure, while further prospective studies are warranted to validate these results.
