Abstract

BACKGROUND: syncope is a common cause of hospitalisation in the elderly. However, morbidity and mortality in elderly patients with syncope is not well established. METHODS: two-hundred and forty-two patients older than 65 years consecutively referred to the participating centres for evaluation of transient loss of consciousness were enrolled in a multicentre 2-year longitudinal observational study. Mortality and syncope recurrences were recorded and multidimensionally evaluated at 6, 12, 18 and 24 months. FINDINGS: at 24 months, total mortality was 17.2% and syncope recurrence was 32.5%. Cardiac syncope was more frequent in deceased than in survivor patients (21.7 versus 12.3%; P = 0.03), whereas neuro-mediated (62.1 versus 66.2%; P = 0.357) and unexplained syncope (10.8 versus 11.8%; P = 0.397) did not differ between the two groups. Drug-induced and/or multifactorial syncope was less frequent in patients with syncope recurrence (5.7 versus 10.7%; P = 0.02). Kaplan-Meyer curves indicated that mortality and syncope recurrence increased significantly with age (P = 0.006 and P = 0.008, respectively). At multivariate analysis, mortality was significantly predicted by age and comorbidity (hazard ratios: 1.17 and 1.39, and 95% confidence interval 1.01-1.37 and 1.01-1.93, respectively), and syncope recurrence by age and disability (hazard ratio: 1.13 and 1.04, 95% confidence interval 1.01-1.25 and 1.04-2.25, respectively). Depression increased from baseline to the end of follow-up (from 28.3 to 41.4%; P = 0.001). CONCLUSIONS: in our patients, mortality was related to increasing age and comorbidity, whereas recurrence was related to increasing age and disability. Cardiac syncope was more frequent in deceased than in survivor patients, and syncope recurrence was high despite a low incidence of unexplained syncope.

  • Among older adults, risks of syncope are usually compounded by multiple morbidities and frailty, which add to age-related vulnerability to syncope.

    “Although some of the risk is attributable to the aspects of syncope described in this guideline, among older adults such risks are usually compounded by multiple morbidities and frailty, which add to age-related vulnerability to syncope (671,681,682), and by the physical injuries associated with falls, collisions, or trauma, which more commonly result from syncope in old age (670).”

    From 2017 ACC/AHA/HRS Guideline for the Evaluation and Management of Patients With Syncope (2017) · cites this paper as [682]

    The Mortality and syncope recurrence section reports that age and comorbidity predicted mortality, while age and disability predicted recurrence in elderly patients with syncope. The Mortality in elderly patients with syncope section describes deceased patients as having characteristics typical of frailty. The paper does not establish that frailty independently compounds risk or that these factors increase older adults’ vulnerability to developing syncope in the first place; its findings concern outcomes after syncope.

  • Orthostatic blood pressure measurements, carotid sinus massage, and tilt testing are well tolerated, even in the frail elderly with cognitive impairment.

    “Orthostatic BP measurements, CSM, and tilt testing are well tolerated, even in the frail elderly with cognitive impairment. 96,396,397”

    From 2018 ESC Guidelines for the diagnosis and management of syncope (2018) · cites this paper as [397]

    The Diagnostic protocol describes tilt testing, carotid sinus massage and orthostatic blood-pressure criteria, but does not report how well patients tolerated the tests. The Methods exclude patients with severe cognitive impairment and substantial disability. Searches for tolerability, adverse events and testing in frail patients with cognitive impairment found no passage establishing the claim. (LLM, conf=0.76)

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.
