In-Hospital Mortality Predictors in Patients with Acute Myocardial Infarction and Cardiogenic Shock Using Intra-Aortic Balloon Pump.

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
backgroundPatients with ST-segment elevation myocardial infarction (STEMI) and cardiogenic shock (CS) have a high risk of death. New types of mechanical devices have limited availability in Brazil. The use of intra-aortic balloon pump (IABP), although new guidelines downgraded its recommendation, is the most widely used mechanical support strategy. However, little is known about the clinical predictors of its effectiveness in reducing mortality in this group of patients.
objectivesTo assess the predictors of IABP effectiveness in reducing in-hospital mortality in patients with STEMI and CS.
methodsThis observational, retrospective, descriptive, single-center study involved 98 patients with STEMI and CS treated with IABP, in an intensive care unit. We compared patients who survived (42 men and 13 women) and those did not (30 men and 13 women) using clinical predictors of IABP effectiveness in reducing in-hospital death, considering a statistical significance level of 5% (p < 0.05).
resultsThe use of IABP in patients less than 1 day after infarction (odds ratio [OR]: 0.12; 95% confidence interval [CI]: 0.02 to 0.85; p = 0.034) was a factor that increased the risk of in-hospital death. Younger age (OR: 1.09; 95% CI: 1.02 to 1.16; p = 0.010) and dyslipidemia (OR: 0.19; 95% CI: 0.05 to 0.81; p = 0.024) were predictors of reduced in-hospital mortality. For each additional year of age, the risk of death increased 1.07-fold.
conclusionIn patients with STEMI and CS, the use of IABP reduced in-hospital mortality when it was used for 2 or more days, as well as in younger patients and those with dyslipidemia. Additional studies are needed to confirm these findings.
