Elevated coated-platelets in symptomatic large-artery stenosis patients are associated with early stroke recurrence

Background Recent prospective registration studies of transient ischemic attack in Western countries demonstrated that large artery atherosclerosis is the highest risk etiology for early stroke recurrence under urgent evaluation and treatment. On the other hand, some limited transient ischemic attack studies from East Asian countries showed transient ischemic attack patients due to small vessel occlusion were at a higher early stroke risk. Aims We aimed to assess the risk for early stroke in small vessel occlusion-transient ischemic attack patients in a Japanese large transient ischemic attack registry. Methods We analyzed the data of a prospective Japanese transient ischemic attack registry including 1320 transient ischemic attack patients within seven days after onset. Small vessel occlusion-transient ischemic attack was defined as the presence of lacunar transient ischemic attack syndrome, without other etiologies. The outcome measure was recurrent stroke within 30 days after transient ischemic attack. The predictors of 30-day recurrent stroke were estimated using the Cox proportional hazards model. Results The study population had a mean age of 69 ± 12 years and 470 were women. Recurrent stroke was observed in 61 patients (4.6%), and the highest rate was observed with small vessel occlusion-transient ischemic attack (7.8%), followed by large artery atherosclerosis (5.4%). In multivariate analysis, recurrent stroke was independently associated with small vessel occlusion-transient ischemic attack (hazard ratio (HR): 2.01, 95% confidence interval (CI): 1.19–3.35), higher systolic blood pressure (HR: 1.18, 95% CI: 1.08–1.28), and presentation within 3 h after onset (HR: 2.21, 95% CI: 1.27–4.04). Furthermore, small vessel occlusion-transient ischemic attack with acute small deep infarct on diffusion-weighted imaging was a stronger predictor of recurrent stroke (HR: 4.87, 95% CI: 2.09–10.0). Conclusion Small vessel occlusion-transient ischemic attack, especially with acute small deep infarct, had a higher early stroke risk compared with other etiologies in Japanese transient ischemic attack patients who received early management.

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.

Background & Purpose: Atrial fibrillation (AF) and large artery atherosclerosis (LAA) can be associated with a bad outcome even in minor stroke. We investigated stroke recurrence and outcome in Japanese minor stroke patients with AF and/or LAA. Subjects & Methods: Among the consecutive 6246 stroke patients who were admitted to the 7 stroke centers within 7 days after the onset, 3725 patients with acute ischemic stroke with the initial NIH stroke scale score of 7 or less and prior modified Rankin scale (mRS) of 0 or 1 were included in the present study. In accordance with AF and intracranial or extracranial LAA (stenosis of 50% or more in diameter), they were classified into 4 subgroups: patients without both AF and LAA (Group A, n=2154), patients with only AF (Group B, n=475), patients with only LAA (Group C, n=937), and patients with both AF and LAA (Group D, n=159). We observed stroke recurrence and outcome during one year. Results: On the multivariate analysis, age (OR, 0.94; 95%CI 0.93~0.95), initial NIH stroke scale score (OR, 0.70; 95%CI, 0.67~0.74), chronic kidney disease (OR, 0.72; 95%CI, 0.55~0.95), initial HbA1c value (OR 0.87, 95%CI 0.79~0.95), and LAA (OR 0.70, 95%CI 0.55~0.88) had a negative association with a good outcome. Acute stroke recurrences within 3 weeks after the onset were observed in 2.0%, 2.5%, 6.1%, and 9.4% in Group A-D patients respectively (p<0.0001). Stroke recurrences during 1 year were observed 7.0%, 10.7%, 11.6%, and 13.8% in Group A-D patients respectively (p<0.0001). A good outcome (mRS of 0-1) 1 year after the onset was observed in 77.0%, 6.4%, 67.9%, and 65.8% in Group A-D patients respectively (p<0.0001). With regard to the Kaplan-Meier method, there was a significant difference in stroke recurrence among the 4 subgroups, and stroke recurrences were most frequent in Group D (p<0.0001, Log-rank test). Conclusions: In Japanese minor stroke, age, NIH stroke scale score, chronic kidney disease, HbA1c, and LAA were significant predictors for the long-term outcome. In patients with both AF and LAA, stroke recurrences were most frequent, especially in the acute phase, and a long-term good outcome was least frequent consequently.
