1 · What the graph read from it

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.

2 · The registry

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 AND

objectivesWe aimed to study temporal trends in cardiogenic shock (CS) complicating acute myocardial infarction (AMI) and assessed the predictors of shock development during hospitalization and of mortality.

methodsData were obtained from 2 Korean AMI Registries (KAMIRs), the KAMIR-National Institutes of Health (early) and KAMIR-V (late). Patients with CS were those with CS before admission (ba-CS) and those who developed CS during admission as a complication of AMI (da-CS). Temporal trends were examined as early (2011-2015) and late (2016-2020) periods.

resultsA total of 28,990 patients was included, of whom 3,179 (11.0%) had CS. The overall prevalence of CS decreased from 12.5% to 9.6% (p for trend <0.001). Among CS patients, 1,900 (59.8% of those with CS) had ba-CS and 1,279 developed da-CS. The prevalence of both ba- (7.1% to 6.1%, p<0.001) and da-CS (5.4% to 3.6%, p<0.001) decreased, while the use of percutaneous coronary intervention increased. Over the 10-year period, in-hospital mortality rates decreased in overall CS (from 27.3% to 22.9%; p=0.004) and ba-CS (from 25.1% to 17.0%; p<0.001), but not in da-CS (from 30.3% to 32.9%; p=0.335).

conclusionsThe decline in mortality rates of overall and ba-CS but not that of da-CS emphasizes the need for enhanced prevention strategies, early identification of development of CS after admission, and alternative therapeutic strategies for patients at high risk of CS in the acute stage of AMI.
