The Prognostic Impact of In-Hospital Major Bleeding and Recurrence of Myocardial Infarction during Acute Phase after Percutaneous Coronary Intervention for Acute Myocardial Infarction.

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
aimBoth recurrent myocardial infarction (ReMI) and bleeding events after acute myocardial infarction (AMI) were reportedly associated with increased mortality. To date, the prognostic impact of these events on subsequent outcomes in East Asians is still unclear. In this study, we aimed to investigate the impact of bleeding or thrombotic events during acute phase on subsequent mortality and time-dependent change of the impact in patients with AMI undergoing percutaneous coronary intervention (PCI).
methodWe conducted a prospective, multicenter, observational study of patients with AMI (n=12,093). The patients who did not undergo emergent PCI were excluded. In addition, the patients registered before 2003 were excluded because the data of bleeding severity was not obtained. Eligible patients were divided into two groups based on the occurrence of major bleeding within 7 days of PCI, and the same approach was performed for ReMI within 7 days of PCI. The endpoint of this study was all-cause death. We assessed the impact of major bleeding and ReMI, which occurred within 7 days of index PCI, on the subsequent clinical outcomes up to 5 years.
resultsA total of 6,769 patients were found to be eligible. All-cause death occurred in 898 (13.3%) patients during a median follow-up period of 1,726 [511-1,840] days. After adjustment for multiple confounders, major bleeding in 7 days from index PCI was independently associated with higher 30-day and 30-day to 1-year mortality (odds ratio [OR]: 2.06 [1.45-2.92] p＜0.001, OR: 2.03 [1.28-3.15] p=0.002), whereas ReMI was not (OR: 1.93 [0.92-3.80] p=0.07, OR: 0.81 [0.24-2.03] p=0.68). Major bleeding and ReMI did not affect mortality between 1 and 5 years (hazard ratio [HR]: 1.32 [0.77-2.26] p=0.31, HR: 0.48 [0.12-1.94] p=0.30).
conclusionMajor bleeding in 7 days from admission was independently associated with higher 30-day and 1-year mortality but not during 1-5 years. ReMI did not affect mortality in all phases. We should be more concerned about bleeding event during acute phase after PCI.
