Atrial fibrillation and stroke in elderly hospitalized patients
Insights
Constant atrial fibrillation (AF) is more strongly linked to stroke than transient AF. This geriatric medicine study found higher stroke prevalence in patients with constant AF compared to those with transient AF.
Area of Science:
- Geriatric Medicine
- Cardiology
- Neurology
Background:
- Atrial fibrillation (AF) is a common cardiac arrhythmia.
- Understanding the stroke risk associated with different types of AF is crucial for patient management.
Purpose of the Study:
- To investigate the association between constant and transient atrial fibrillation and stroke prevalence in geriatric patients.
Main Methods:
- Analysis of 4100 consecutive geriatric admissions.
- Identification of patients with atrial fibrillation (AF), categorizing them into transient and constant types.
- Comparison of stroke prevalence between AF groups and a control group in sinus rhythm.
Main Results:
- 10.1% of admissions had AF (414 patients).
- Constant AF patients showed a higher stroke prevalence (41.7%) compared to transient AF patients (26.8%).
- Patients in sinus rhythm had a 19% stroke prevalence.
Conclusions:
- Constant atrial fibrillation demonstrates a significantly greater association with stroke than transient atrial fibrillation in the geriatric population.
- Findings highlight the importance of differentiating AF types for stroke risk assessment.
Abstract:
Of 4100 consecutive admissions to the Department of Geriatric Medicine, 414 patients (10.1%) were identified as having atrial fibrillation (AF); 138 (33%) had transient AF and 276 (67%) had constant AF. In the constant group, 41.7% of patients had had a stroke compared with 26.8% in the transient group (P less than 0.01). A random sample of 200 patients in sinus rhythm from the 4100 admissions had a stroke prevalence of 19%. This study suggests that constant AF has a greater association with stroke than transient AF.
