Cardiogenic shock in the course of myocardial infarction: the results of the Shock-POL registry.
Article in ESC heart failure, 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
aimsCardiogenic shock (CS) represents an ominous complication of acute myocardial infarction (AMI) with a mortality rate exceeding 50%. The aim of the study was to evaluate current management, outcomes, and risk factors of mortality of AMI-related CS.
methodsThis snapshot registry evaluated all patients with AMI-related CS hospitalized in 9 cardiology centres across Poland between January and December 2023. The inclusion criteria involved CS defined as prolonged (>20 min) hypotension with signs of peripheral hypoperfusion and a diagnosis of AMI qualified for urgent coronary angiography. The primary endpoint was in-hospital mortality.
resultsThe study comprised 141 patients (72.3% men; mean age was 69.2 [14] years). The majority of patients were in Society for Cardiovascular Angiography and Interventions class C (n = 71, 50.4%), followed by class D (n = 46, 32.6%) and class E (n = 24, 17.0%). Percutaneous coronary intervention was performed in 133 cases (94.3%) while coronary artery bypass graft in 5 (3.5%). Mechanical circulatory support (MCS) was used in 33 patients (23.4%) and involved intra-aortic balloon pump (n = 26, 18.4%), Impella CP (n = 6, 4.3%), Impella 5.5 (n = 2, 1.4%), and veno-arterial extracorporeal membrane oxygenation (n = 10, 7.1%). In-hospital mortality rate was 47.5% (n = 67), while 30-day mortality was 51.8% (n = 73). Cox proportional hazards model showed that non-ST-elevation AMI (HR = 2.38, 95%CI: 1.19-4.75), lack of the need for antibiotic therapy (HR = 2.61, 95%CI: 1.26-5.39), elevated lactates (unit HR per 1 mmol/l = 1.19, 95%CI: 1.11-1.27) and age (unit HR = 1.05; 95%CI: 1.02-1.07) were independent predictors of in-hospital mortality.
conclusionsShort-term mortality rate of AMI-related CS still amounts to 50%, which advocates in favour of further research evaluating the true role of MCS in this population.
