The increasing burden of atrial fibrillation in acute medical admissions, an opportunity to optimise stroke prevention.

Background Atrial fibrillation is a major risk factor for ischaemic stroke. We investigated whether active screening for atrial fibrillation in secondary care, followed by careful evaluation of risk factors and communication to general practitioners from stroke specialists, could increase appropriate anticoagulation prescription. Methods Between 1/9/14 and 28/2/15 all acute medical admissions were screened for atrial fibrillation at Cambridge University Hospital. Individualised letters were sent to the general practitioners of patients who it was felt would benefit from anticoagulation. Results In total, 847 patients with atrial fibrillation (15% prevalence, 52% female, median age 81.9 years, median CHA2DS2-VASc 4.4) were identified; 671 (79.2%) had known atrial fibrillation, and 176 (20.8%) were diagnosed on admission. After screening and identifying 'at risk' patients, 112 individualised letters were sent to GPs. A 91% response rate was achieved, resulting in an additional 43 individuals being appropriately anticoagulated. Conclusions Atrial fibrillation prevalence is significantly increasing among acute hospital admissions; these patients have high risk of cardioembolic stroke. Careful screening and identification in secondary care can lead to improved rates of anticoagulation.

Falls and fractures 2 years after acute stroke: the North Dublin Population Stroke Study.

BACKGROUND: Stroke patients are at increased risk of falls and fractures. The aim of this study was to determine the rate, predictors and consequences of falls within 2 years after stroke in a prospective population-based study in North Dublin, Ireland. DESIGN: Prospective population-based cohort study. SUBJECTS: 567 adults aged >18 years from the North Dublin Population Stroke Study. METHODS: Participants were enrolled from an Irish urban population of 294,592 individuals, according to recommended criteria. Patients were followed for 2 years. Outcome measures included death, modified Rankin Scale (mRS), fall and fracture rate. RESULTS: At 2 years, 23.5% (124/522) had fallen at least once since their stroke, 14.2% (74/522) had 2 or more falls and 5.4% (28/522) had a fracture. Of 332 survivors at 2 years, 107 (32.2%) had fallen, of whom 60.7% (65/107) had 2 or more falls and 23.4% (25/107) had fractured. In a multivariable model controlling for age and gender, independent risk factors for falling within the first 2 years of stroke included use of alpha-blocker medications for treatment of hypertension (P = 0.02). When mobility measured at Day 90 was included in the model, patients who were mobility impaired (mRS 2-3) were at the highest risk of falling within 2 years of stroke [odds ratio (OR) 2.30, P = 0.003] and those functionally dependent (mRS 4-5) displayed intermediate risk (OR 2.02, P = 0.03) when compared with independently mobile patients. CONCLUSION: Greater attention to falls risk, fall prevention strategies and bone health in the stroke population are required.

Stroke recurrence within the time window recommended for carotid endarterectomy.

OBJECTIVE: In the North Dublin Population Stroke Study, we investigated the risk of recurrent stroke within the 14-day time window recommended for endarterectomy. METHODS: In a population-based prospective cohort study, all ischemic stroke patients were identified over 1 year and categorized into those with (CS-positive) and without (CS-negative) ipsilateral carotid stenosis (CS) (≥50% lumen narrowing). Nonprocedural stroke recurrence was determined at 72 hours and 7 and 14 days. RESULTS: Of 365 ischemic stroke patients with carotid imaging, 51 were excluded due to posterior circulation or nonlateralizing stroke, ipsilateral carotid occlusion, or intracranial stenosis, leaving 314 included for analysis (36 CS-positive and 278 CS-negative). Recurrent stroke occurred in 5.6% (2/36) CS-positive and 0.4% (1/278) CS-negative patients by 72 hours of symptom onset (p =0.003), 5.6% (2/36) CS-positive and 0.7% (2/278) CS-negative patients (p =0.01) by 7 days, and in 8.3% (3/36) CS-positive and 1.8% (5/278) CS-negative patients by 14 days (p =0.02). On multivariable Cox regression analysis, CS was the only independent predictor of recurrence at 72 hours (adjusted hazard ratio [HR] 36.1, 95% confidence interval [CI] 1.6-837.5, p =0.03), and 7 days (HR 9.1, 1.1-79.2, p =0.05), with a trend at 14 days (HR 4.6, 0.9-22.8, p =0.06). CONCLUSIONS: Although only a minority of patients with symptomatic CS had a recurrent stroke within 14 days, early recurrent stroke risk was high, particularly within the first 72 hours. Earlier carotid revascularization or improved acute medical treatment may reduce recurrence in this high-risk group.

Anticipatory grief and aged widows and widowers.

The purpose of this investigation was to explore the preventive value of anticipatory grief on the medical adjustment of the aged bereaved. Data were collected for 81 surviving widows and widowers 6 mo. after their loss. Sixteen of the bereaved had spouses who died of a chronic illness. These two groups were compared on three criteria of medical adjustment: physician office visits, feeling ill without contacting a physician, and use of psychotropic medications. The data indicated that the aged bereaved of a lengthy chronic fatal illness did worse than the bereaved of a shorter chronic illness death. By sex, no significant differences were found between widows and widowers of a short-term illness death. However, differences were noted for the chronic illness category, and within this category for length of chronicity. In both cases widowers showed more medical problems than widows.
