Background and Objective: Patients with transient ischemic attack（TIA）occasionally showed nonfocal symptoms, such as decreased consciousness, amnesia and non-rotatory dizziness. This study intended to evaluate the effect of nonfocal symptoms on the prognosis of patients with TIA. Methods: Data from the prospective hospital-based TIA database of the First Affiliated Hospital of Zhengzhou University were analyzed. The predictive outcome was stroke occurrence at 1 year. Cumulative risks of stroke in patients with and without nonfocal symptoms were estimated with Kaplan-Meier models. Results: We studied 1384 patients with TIA (842 men; mean age, 56±13 years), including 450 (32.5%) with nonfocal symptoms. In the first year after TIA, stroke occurred in 168（12.1%） patients. There was no difference in the risk of stroke between patients with both focal and nonfocal symptoms and patients with focal symptoms alone (11.8% vs 12.4%, log-rank; P=0.691). Conclusions: The occurrence of nonfocal symptoms did not increase the risk of stroke at one-year follow-up compared to the occurrence of focal symptoms alone.

Background and Purpose— Little was known about the predictive accuracy of the Essen Stroke Risk Score and the Stroke Prognostic Instrument II in Chinese patients with stroke. Methods— We evaluated the predictive accuracy of both Essen Stroke Risk Score and Stroke Prognostic Instrument II scores for both recurrent stroke and combined vascular events using data from a prospective cohort of 11 384 patients with acute ischemic stroke and transient ischemic attack admitted to 132 urban hospitals throughout China. Results— The cumulative 1-year event rates were 16% (95% CI, 15%–16%) for recurrent stroke and 18% (95% CI, 18%–19%) for combined vascular events. Both event rates were significantly higher in patients with transient ischemic attack and increased significantly from lower to higher Essen Stroke Risk Score and Stroke Prognostic Instrument II categories. Essen Stroke Risk Score and Stroke Prognostic Instrument II had similar predictive accuracies for each study outcome. Conclusions— In Chinese patients with ischemic stroke or transient ischemic attack, both Essen Stroke Risk Score and Stroke Prognostic Instrument II scores are equally able to stratify the risk of recurrent stroke and combined vascular events.

Ischemic Attack

Background: The risk of stroke after cardiac and carotid surgery is well established. In contrast, stroke risk in association with non-cardiac and non-carotid surgery and its time course are insufficiently known. We investigated the prevalence of recent and planned surgery among patients with stroke and transient ischemic attack (TIA), time dependency of stroke risk, stroke etiology, and interruption of antithrombotic medication in association with surgery. Methods: Data on type and date of surgery and similar interventions within the last year or planned for the next 2 weeks were anonymously collected together with demographic data, vascular risk factors, stroke severity, handicap before stroke and stroke etiology within a state-wide, mandatory, hospital-based acute stroke care quality monitoring project (Rhineland-Palatinate, Germany) for 1 year (2010). Results: Non-carotid and non-cardiothoracic surgery was reported as performed within 1 year before the index event or as planned for the next 2 weeks thereafter in 532 out of 12,120 patients with ischemic stroke/TIA (4.4%). Compared to 91-365 days before stroke/TIA as reference period, risk of cerebral ischemia (per day analysis) was increased for surgery within 61-90 days before ischemia (rate ratio 2.0, 95% CI 1.5-2.8) and continuously increased along shorter intervals between stroke and surgery (31-60 days: rate ratio 3.6, 95% CI 2.9-4.5; 15-30 days: rate ratio 8.2, 95% CI 6.7-10.1; 8-14 days: rate ratio 13.2, 95% CI 10.3-16.8; 4-7 days: rate ratio 16.5, 95% CI 12.2-22.1) peaking at an interval of 1-3 days before ischemia (rate ratio 34.0, 95% CI 26.9-42.8). On the day of surgery, rate ratio was 14.8 (95% CI 7.8-27.9) and for planned surgery it was 2.7 (95% CI 1.8-4.0). Results were similar for first-ever and for recurrent ischemic stroke. Perioperative stroke/TIA was positively associated with atrial fibrillation and cardioembolic stroke etiology, higher mortality, more severe neurological deficits at discharge, and longer hospital stay; and it was inversely associated with microangiopathic etiology and discharge at home. In 34.5% of patients with recent/planned surgery, prior antithrombotic or anticoagulant medication had been interrupted. Conclusions: Recent or planned surgery imposes a considerable short-term stroke risk particularly by cardioembolism with cessation of medication as an important contributor. Stroke after surgery is associated with poor outcome and high mortality. Better strategies to reduce the burden of perioperative stroke are urgently required.
