Sažetak
Objective: Our objective was to investigate the predictors of falls requiring a visit to the emergency department in patients with nonvalvular atrial fibrillation (AF) receiving different types of anticoagulants and to investigate the clinical consequences of falling in the same population. Methods: A total of 1217 patients with nonvalvular AF from two institutions were retrospectively evaluated. Each patient underwent a physical examination, and clinical histories and medication profiles were taken from each patient at baseline. Results: The median age of our cohort was 71 years ; 52.3% were males, and 86.1% of patients were receiving anticoagulation at study baseline. The 5-year freedom-from-falling rate was 81.6%. The use and type of anticoagulation was not significantly associated with the risk of falling (P = 0.222), whereas higher Morse Fall Scale (MFS), CHA2DS2-VASC (congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke or transient ischemic attack, vascular disease, age 65-74 years, sex category), and HAS- BLED (hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly [> 65 years], drugs/alcohol concomitantly) scores were significantly associated with a higher hazard of the first fall in univariate analyses. In the multivariate Cox regression model, MFS, older age, osteoporosis, higher levels of high-density lipoprotein cholesterol, higher diastolic blood pressure, and use of amiodarone, diuretics, or short- and medium-acting benzodiazepines were mutually independent predictors of the first fall. Of 163 patients, 93 (57%) had a bone fracture during the fall. Type of anticoagulation significantly affected survival after the first fall (P < 0.001): patients inadequately anticoagulated with warfarin had worse survival rates, and patients receiving apixaban and dabigatran had the best survival rates after the first fall. Conclusion: Older patients who had comorbidities and were taking amiodarone, diuretics, or short- or medium-acting benzodiazepines had the highest risk of falls. The type and quality of anticoagulation did not seem to affect the risk of falling but did significantly affect survival after the first fall.
