Ischemic Attack

Background and Purpose— The clinical diagnosis of a transient ischemic attack (TIA) can be difficult. Evidence-based criteria hardly exist. We evaluated if the recently proposed Explicit Diagnostic Criteria for TIA (EDCT), an easy to perform clinical tool focusing on type, duration, and mode of onset of clinical features, would facilitate the clinical diagnosis of TIA. Methods— We used data from patients suspected of a TIA by a general practitioner and referred to a TIA service in the region of Utrecht, the Netherlands, who participated in the MIND-TIA (Markers in the Diagnosis of TIA) study. Information about the clinical features was collected with a standardized questionnaire within 72 hours after onset. A panel of 3 experienced neurologists ultimately determined the definite diagnosis based on all available diagnostic information including a 6-month follow-up period. Two researchers scored the EDCT. Sensitivity, specificity, and predictive values of the EDCT were assessed using the panel diagnosis as reference. A secondary analysis was performed with modified subcriteria of the EDCT. Results— Of the 206 patients, 126 (61%) had a TIA (n=104) or minor stroke (n=22), and 80 (39%) an alternative diagnosis. Most common alternative diagnoses were migraine with aura (n=24; 30.0%), stress related or somatoform symptoms (n=16; 20.0%), and syncope (n=9; 11.3%). The original EDCT had a sensitivity of 98.4% (95% CI, 94.4–99.8) and a specificity of 61.3% (49.7–71.9). Negative and positive predictive values were 96.1% (86.0–99.0) and 80.0% (75.2–84.1), respectively. The modified EDCT showed a higher specificity of 73.8% (62.7–83.0) with the same sensitivity and a similar negative predictive value of 96.7%, but a higher positive predictive value of 85.5% (80.3–89.5). Conclusions— The EDCT has excellent sensitivity and negative predictive value and could be a valuable diagnostic tool for the diagnosis of TIA.

Ischemic Attack

Background: We have reported 5-year risk of stroke and vascular events after a transient ischemic attack (TIA) or minor ischemic stroke in patients enrolled into the TIAregistry.org, which was an international multicenter-cooperative, prospective registry (N Engl J Med 2018;378:2182-90). We conducted subanalysis on the 5-year follow-up data of Japanese patients in comparison with non-Japanese patients. Methods: The patients were classified into two groups on ethnicity, Japanese (n=345) and non-Japanese (n=3502), and their 5-year event rates were compared. We also determined predictors of five-year stroke in both groups. Results: Death from vascular cause (0.9% vs 2.7%, HR 0.28, 95% CI 0.09-0.89, p=0.031) and death from any cause (7.8% vs 9.9%, HR 0.67, 95% CI 0.45-0.99, p=0.045) were fewer in Japanese patients than in non-Japanese patients, while stroke (13.9% vs 7.2%, HR 1.78, 95% CI 1.31-2.43, p<0.001) and intracranial hemorrhage (3.2% vs 0.8%, HR 3.61. 95% CI 1.78-7.30, p<0.001) were more common in Japanese than non-Japanese patients during five-year follow-up period. Caplan-Meyer curves at five-years showed that the rates of stroke was also significantly higher in Japanese than non-Japanese patients (log-rank test, p=0.001). Predictors for stroke recurrence at five years were large artery atherosclerosis (HR 1.81, 95% CI 1.31-2.52, p<0.001), cardioembolism (HR 1.71, 95% CI 1.18-2.47, p=0.004), multiple acute infarction (HR 1.77, 95% CI 1.27-2.45, p<0.001) and ABCD 2 score 6 or 7 (HR 1.96, 95% CI 1.38-2.78, p<0.001) in non-Japanese patients, although only large artery atherosclerosis (HR 3.28, 95% CI 1.13-9.54, p=0.029) was a predictor for stroke recurrence in Japanese patients. Conclusions: Recurrence of stroke and intracranial hemorrhage were more prevalent in Japanese than non-Japanese patients. Large artery atherosclerosis was a predictor for stroke recurrence not only in non-Japanese patients but also in Japanese patients.

In this study, in order to evaluate the feasibility and outcomes of simultaneous bilateral carotid artery stenting (CAS) with the use of neuroprotection in symptomatic patients, we conducted a retrospective analysis of 27 patients (19 men, eight women; median age, 69.2 years), all of whom had been scheduled to undergo bilateral CAS in a single setting. All patients presented with severe atherosclerotic bilateral carotid stenosis (>50% for symptomatic side, >80% for asymptomatic side), exhibiting symptoms of either a cerebrovascular accident or of a transient ischemic attack on at least one side. 48 arteries were treated with self-expandable stents. Neuroprotection devices were utilized for bilateral CAS in 11 patients, and in 16 unilateral CAS patients. We did not perform the second procedure in six patients, in cases in which a patient exhibited (a) hemodynamic instability, (b) a new neurological impairment, or (c) restlessness after a prolonged time for the first CAS. The second procedure was postponed in a staged manner. We achieved a mean residual stenosis of 8.1 ± 5.0 % in the treated lesions. The mean procedural time for bilateral CAS was three hours and 18 minutes. 17 patients (63%) developed transient bradycardia during the balloon dilatation of one or both of the relevant arteries. Three patients (11%) exhibited persistent bradycardia and hypotension, which required the administration of intravenous vasopressors for several days (2!7 days). None of the patients ultimately required pacemakers, or any further therapy. Two of the patients (7%) developed transient ischemic attack during the periprocedural period, but recovered completely. One patient developed a new minor stroke after the first procedure, and the second procedure was delayed in a staged manner. We observed no periprocedural deaths, major strokes, or myocardial infarctions, nor did we detect any cases of hyperperfusion syndrome within 30 days. In summary, simultaneous bilateral CAS with neuroprotection can be performed in a single setting without increased concerns with regard to hyperperfusion syndrome, hemodynamic instability, thrombo-embolism, or procedure time, when the first CAS has been safely completed with no evidence of complications in a well-managed procedure time.
