Associations between Chest Pain, Diagnosis, and Clinical Outcome in Patients Hospitalized with Acute Dyspnea: Data from the ACE 2 Study.

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
introductionPatients hospitalized due to dyspnea sometimes also report concomitant chest pain. Whether co-existing chest pain in patients with acute dyspnea associates with specific diagnosis and clinical outcome is not known.
methodWe included 313 patients admitted to Akershus University Hospital with acute dyspnea and asked the patients directly on hospital admission whether they had experienced chest pain during the last 24 h. We examined the associations between chest pain and (1) diagnosis of the index hospitalization and (2) clinical outcome during follow-up. The diagnosis for the index hospitalization was adjudicated as acute heart failure (HF) or non-HF etiology of acute dyspnea by two experts working independently. Non-HF patients were further sub-grouped into chronic obstructive pulmonary disease (COPD) or non-COPD etiology.
resultsIn total, 143 patients were admitted with acute HF (46% of the population), 83 patients with COPD (26% of the population), and 87 patients with non-HF, non-COPD-related dyspnea (28% of the population). Ninety-six patients (31%) with acute dyspnea reported chest pain during the last 24 h prior to hospital admission. The prevalence of chest pain was not statistically different for patients who were hospitalized with acute HF (n = 42, 44%), acute exacerbation of COPD (n = 22, 23%), or non-HF, non-COPD-related dyspnea (n = 32, 33%), p > 0.05 for all comparisons between groups. During median of 823 days follow-up, 114 patients died (36%). Patients with dyspnea and concomitant chest pain did not have different outcome compared to patients with dyspnea and no chest pain (log-rank test: p = 0.09). Chest pain prior to admission was neither associated with all-cause mortality in any of the adjudicated diagnosis groups.
conclusionsChest pain was reported in 31% of patients hospitalized with acute dyspnea but the prevalence did not differ according to adjudicated diagnosis. Patients with dyspnea and chest pain did not have worse outcome compared to patients with dyspnea and no chest pain.
