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

aimsPatients who survive acute myocardial infarction (AMI) are at risk of being rehospitalized owing to the occurrence of acute decompensated heart failure (HF). However, the clinical characteristics of HF after AMI, especially the frequency of each HF subtype, are unclear. METHODS AND

resultsWe retrospectively studied 1055 patients with AMI. We excluded 257 patients, who were admitted >48 h after the onset of AMI, died during hospitalization or after discharge, and whose echocardiogram data at index hospitalization and follow-up data were missing. The remaining 798 patients (mean age: 66.5 ± 11.7 years) were investigated for a mean follow-up period of 4.9 years. All patients underwent emergency coronary angiography. The mean maximum creatine kinase levels were 2898 ± 2627 IU/L, and mean left ventricular ejection fraction (LVEF) was 58.9 ± 10.2%. Eighty-one patients (10.2%) were rehospitalized because of unexpected worsening of HF. Echocardiography data were available for 74 of the 81 patients during the acute phase of the second hospitalization, of which 30, 20, and 24 patients (41%, 27%, and 32%, respectively) were diagnosed as having HF with preserved LVEF (LVEF ≥ 50%), HF with mid-range LVEF (40% ≤ LVEF < 50%), and HF with reduced LVEF (LVEF < 40%), respectively. The ejection fraction during index hospitalization was 58.3 ± 9.7% in the HF with preserved LVEF group, 53.3 ± 10.2% in the HF with mid-range LVEF group, and 43.3 ± 10.5% in the HF with reduced LVEF group (P < 0.001).

conclusionsThe predominant subtypes of HF after AMI were HF with mid-range ejection fraction and preserved ejection fraction, or HF with non-reduced ejection fraction.
