Background:In Japan, warfarin treatment at prothrombin time-international normalized ratio (PT-INR) of 1.60–2.60 is recommended for elderly patients with nonvalvular atrial fibrillation (NVAF). But it remains unknown whether PT-INR 1.60–1.99 has a similar effect on stroke severity as a value >2.0. The purpose of this study was to clarify the association between infarct volume and PT-INR levels.Methods and Results:The 180 patients (mean age, 76 years [SD, 10 years], 53% male) selected from 429 consecutive ischemic stroke patients admitted within 48 h of onset between 2004 and 2014 with NVAF were included. We classified them into 4 groups according to their PT-INR values on admission: no warfarin (NW), 129 patients; PT-INR <1.60 (poor control: PC), 29 patients; PT-INR 1.60–1.99 (low-intensity control: LC), 14 patients; and PT-INR ≥2.00 (high-intensity control: HC), 8 patients. Median (interquartile range: IQR) of infarct volume was 55 mL (IQR 14–175) in the NW, 42 mL (IQR 27–170) in the PC, 36 mL (IQR 6–130) in the LC, and 11 mL (IQR 0–39) in the HC groups. The infarct volume of the HC group was significantly smaller than in the other 3 groups, but no difference existed between the LC and PC groups or the LC and NW groups.Conclusions:Warfarin control at PT-INR of 1.60–1.99 is not effective for reducing the severity of ischemic stroke in NVAF patients.

Aims: To investigate the relative contribution of on-treatment low-density lipoprotein (LDL) cholesterol and C-reactive protein (CRP) to the risk of recurrent stroke and transient ischemic attack (TIA) in patients with history of ischemic stroke.Methods: A total of 1095 patients with non-cardioembolic ischemic stroke were randomized into two groups: control and patients receiving 10 mg of pravastatin per day. After excluding 18 patients who did not have baseline CRP data, the effects of LDL cholesterol and CRP on recurrent stroke and TIA were prospectively assessed in 1077 patients.Results: During the follow-up of 4.9±1.4 years, there were 131 recurrent stroke or TIA cases. Patients with ontreatment LDL cholesterol <120 mg/dL showed 29% reduction in recurrent stroke and TIA than those with LDL cholesterol ≥ 120 mg/dL (event rate 2.20 vs. 3.11 per 100 person-years, hazard ratio [HR] 0.71, 95% confidence interval (CI) 0.50–0.99, p=0.048). Patients with CRP <1 mg/L had 32% reduction compared with that of patients with CRP ≥ 1 mg/L (event rate 2.26 vs. 3.40 per 100 person-years; HR 0.68, 95% CI 0.48–0.96, p=0.031). Although LDL cholesterol and CRP levels were not correlated in individual patients, those who achieved both LDL cholesterol <120 mg/dL and CRP <1 mg/L showed 51% reduction compared with that of patients with LDL cholesterol ≥ 120 mg/dL and CRP ≥ 1 mg/L (event rate 2.02 vs. 4.19 per 100 person-years; HR 0.49, 95% CI 0.31–0.79).Conclusions: The control of both LDL cholesterol and CRP levels appears to be effective for preventing recurrent stroke and TIA in patients with non-cardiogenic ischemic stroke.

Background: The diagonal ear-lobe crease (ELC) is reported to be a marker of cardiovascular disease. Very few reports have assessed the relationship of ELC with atherosclerosis. This relationship is investigated here using a Japanese population. Methods and Results: A prospective cross-sectional study included 212 consecutive patients. Bilateral ear lobes were checked for the ELC and this was followed by carotid ultrasonography to measure the far wall common carotid artery intima-media thickness (CCA-IMT), plaque score (PS) and plaque number (PN). Patients with ELC had significantly higher carotid IMT than controls (0.90 ±0.24 vs 0.77 ±0.15, respectively, P<0.001). ELC presence correlated significantly with carotid IMT, PS, and PN (r=0.306, P<0.0001; r=0.198, P<0.008 and r=0.221, P<0.0001, respectively), and also with age, male sex and hypertension. ELC presence and absence in mild or no PS and moderate or severe PS subgroups was significant, with a chi-squared value of 7.59 (P<0.006). In multivariate regression analysis, ELC presence correlated with CCA-IMT independently. The odds ratio for the presence of ELC in patients with CCA-IMT of <0.8 mm vs patients with CCA-IMT of ≥0.8 mm (the median value) was 0.41 (95% confidence interval, 0.22-0.76). Conclusions: The present study showed an association between ELC and increased CCA-IMT, PS, and PN. (Circ J 2009; 73: 1945-1949)
