Is syncope a risk factor for poor outcomes? comparison of patients with and without syncope
Abstract
Objective To determine whether syncope, independent of underlying comorbidities, is associated with increased mortality or other cardiovascular outcomes. Patients and methods A prospective cohort study of patients with syncope and a group of patients without syncope matched with respect to age, gender, site of care (inpatient/ outpatient) and a cardiac disease index at an urban university medical center. Overall mortality, cardiac mortality, cardiovascular outcomes, and occurrence of syncope within 1 year of study enrollment were compared between the groups with Kaplan-Meier rates and Mantel-Cox statistics. Results The characteristics of 470 patients with syncope and the matched patients without syncope were similar except that the patients without syncope had more cardiac diseases than those with syncope (P = 0.002). Patients with and without syncope had similar rates of 1-year overall mortality (9% versus 11%, P = 0.29) and cardiac mortality (3% versus 6%, P = 0.08). In multivariate analyses, syncope was not a significant predictor of overall or cardiac mortality, but male gender, age > 55 years, and congestive heart failure were. One-year rates for other cardiovascular outcomes (myocardial infarction, congestive heart failure, cardiac arrest with survival, and cerebrovascular events) in patients with syncope were similar to those in patients without syncope (P > or = 0.2 for all comparisons). Patients with syncope had a 20.2% recurrence rate in 1 year as compared with a 2.…

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
