“…7 In agreement with Dennis et al, 3 we found that attacks of monocular symptoms alone were associated with a better prognosis. This suggests that factors other than atherosclerotic disease (for instance, vasospasm 8 ) can cause transient monocular blindness, whether or not related to migraine. In addition, we found that rotatory dizziness also implied a lower risk.…”

The Dutch TIA Trial Study Group Background and Purpose: Very few studies have addressed the identification of prognostic factors in patients with a transient ischemic attack or minor stroke.Methods: We prospectively studied the prognostic value of clinical, laboratory, radiological, and electrocardiographic findings in 997 patients with a transient ischemic attack and 2,130 patients with a minor stroke who were entered into a multicenter clinical trial. The mean follow-up period was 2.6 years.Results: A total of 302 patients died (212 from a vascular cause), 272 had a stroke, and 200 had a cardiac event. By means of a multivariate analysis we identified the following independent risk factors for stroke, myocardial infarction, or vascular death: age of >65 years; male sex; dysarthria; multiple attacks; diabetes; angina pectoris; intermittent claudication; computed tomographic evidence of any cerebral infarct, especially a border zone infarct or white matter hypodensity; and electrocardiographic evidence of an anteroseptal infarct, ST depression, left ventricular hypertrophy, or left atrial conduction delay. Protective predictors were monocular attacks only or the presence of rotatory dizziness.

“…Retinal artery spasm observed during attacks of classic amaurosis fugax would certainly support this possibility, as would the repetitive nature of migrainous hemiplegic events on some occasions [32,33] . But vasospasm has not been documented in small penetrating arteries.…”

Transient Ischemic Attacks Preceding Acute Lacunar Infarction

et al. 2016

Background: It has been reported that some patients with lacunar infarction have transient ischemic attacks (TIAs) before stroke. This study was aimed at evaluating the factors and prognostic value related to TIAs preceding acute lacunar stroke. Methods: A total of 1,424 patients were admitted to the hospital for first-ever ischemic stroke. Of which 314 patients with acute lacunar infarction were enrolled for this study. The patients were divided into 2 groups based on the occurrence of TIAs before stroke. Results: Fifty-eight patients (18.5%) had a history of preceding TIAs. The interval between TIA and stroke was less than 24 h in most patients (87.9%). Diabetes mellitus was more often found in patients with TIAs than in those without TIAs (48.3 vs. 28.9%, p = 0.004). Initial National Institute of Health Stroke Scale scores showed no significant difference between the 2 groups (median 2 vs. 3, p = 0.067). However, patients with preceding TIAs had a more favorable outcome (modified Rankin scale 0-1) than those without TIA at 3 months after stroke (79.6 vs. 63.2%, p = 0.021). Conclusion: Lacunar TIA may occur due to small perforating microatheromatous arteries caused by diabetes. This study suggests that ischemic tolerance may play a role in patients with preceding TIAs before lacunar infarct, allowing better recovery from a subsequent ischemic stroke.
