Arterial stiffness is an independent predictor of cardiovascular disease and stroke and can be evaluated by measuring pulse wave velocity(PWV) between 2 sites in the arterial tree, with a higher PWV indicating stiffer arteries. Recent studies have demonstrated that arterial stiffness is associated with intracranial large artery disease and the severity of cerebral small vessel disease. The aim of this study is to clarify whether pulse wave velocity value predict initial severity of acute ischemic stroke. We enrolled consecutive patients with acute ischemic stroke. Demographic factors, laboratory data, brain imaging, neurological exam and arterial stiffness measured by brachial ankle PWV (baPWV) were evaluated on admission in all subjects. The subtype of acute ischemic stroke was classified according to the TOAST classification. All patients were categorized into two groups based on the initial severity of stroke, indicated by modified Rankin Scale(mRS). Severe group was defined as a mRS ≥ 3 at admission. Unpaired student’s t-test or Mann-whitney U-test were used to compare maximal and meanbaPWV values between two groups. We enrolled 78 patients. According to the TOAST classification, the etiology of stroke was large artery disease (LAD) in 34 patients, small vessel disease (SVD) in 23 patients, and other subtypes in 12 patients. There were 28 patients with good outcome and 41 patients with poor outcome. The maximal and mean baPWV values were significantly increased in inpatients with high mRS score (2120.17± 527.75, 1999.21 ± 437.46) compared with those with low mRS score (1751.96 ± 363.49, 1723.14 ± 353.02)(p=0.001, p=0.007). In patients with SVD subtype, there was significant difference in maximal and mean baPWVvalues between two groups (p=0.030, p=0.047), whereas there was no significant difference in baPWV in patients with LAD subtype (p=0.141, p=0.172). The main finding of our study is that arterial stiffness indicated by baPWV is associated with the initial severity of acute ischemic stroke. Because initial stroke severity is strongly associated with functional outcome of stroke, this findings suggest that measurement of baPWV may predict long-term outcome in patients with stroke especially in those with TOAST classification confirmed as SVD.

Background: There is little information concerning the invasive coronary angiography (ICA) findings of patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA) with elevated troponin levels and suspected myocardial infarction (MI). This study analyzed patient characteristics associated with ICA outcomes.Methods: A total of 8,322 patients with AIS or TIA, treated between March 2010 and May 2020, were retrospectively screened for elevated serum troponin I at hospital admission. Patients in whom ICA was performed, due to suspected type 1 MI based on symptoms, echocardiography, and ECG, were categorized according to ICA results (non-obstructive coronary artery disease (CAD): ≥1 stenosis ≥50% but no stenosis ≥80%; obstructive CAD: any stenosis ≥80% or hemodynamically relevant stenosis assessed by FFR/iwFR).Results: Elevated troponin levels were detected in 2,205 (22.5%) patients, of whom 123 (5.6%) underwent ICA (mean age 71 ± 12 years; 67% male). CAD was present in 98 (80%) patients, of whom 51 (41%) were diagnosed with obstructive CAD. Thus, ICA findings of obstructive CAD accounted for 2.3% of patients with troponin elevation and 0.6% of all stroke patients. The clinical hallmarks of myocardial ischemia, including angina pectoris (31 vs. 15%, p < 0.05) and regional wall motion abnormalities (49 vs. 32%, p = 0.07), and increased cardiovascular risk indicated obstructive CAD. While there was no association between lesion site or stroke severity and ICA findings, causal large-artery atherosclerosis was significantly more common in patients with obstructive coronary disease (p < 0.05).Conclusion: The rate of obstructive CAD in patients with stroke or TIA and elevated troponin levels with suspected concomitant type I MI is low. The cumulation of several cardiovascular risk factors and clinical signs of MI were predictive. AIS patients with large-artery atherosclerosis and elevated troponin may represent an especially vulnerable subgroup of stroke patients with risk for obstructive CAD.

Background Studies regarding long-term outcomes of ischemic stroke subtypes are scarce in low- and middle-income countries. We aimed to measure the five-year prognosis of ischemic stroke subtypes in Joinville, Brazil. Methods All first-ever ischemic strokes that occurred in Joinville in 2010 were followed-up for five years. Results We included 334 ischemic stroke patients. Over five years, 156 died, 51 had a recurrent stroke, and 128 were free of recurrent stroke. The overall cumulative risk of death was 17% (95% CI, 13% to 22%) at 30 days and 47% (95% CI, 41% to 52%) after five years. Undetermined with incomplete investigation ischemic stroke had a significantly worse survival probability (β −4.91; 95% CI, −6.31 to −3.50; p < 0.001), followed by cardioembolic ischemic stroke (β −3.07; 95% CI, −4.32 to −1.83; p < 0.001) and large artery disease ischemic stroke (β −1.95; 95% CI, −3.30 to −0.60; p = 0.005). The survival probability of undetermined with negative investigation or cryptogenic ischemic stroke did not differ significantly from small artery disease ischemic stroke (β −1.022; 95% CI, −3.37 to −1.43; p = 0.414). The five-year mortality for small artery disease ischemic stroke was 30% (95% CI, 22% to 39%) and 47% (95% CI, 35% to 60%) for large artery ischemic stroke. The risk of stroke recurrence was 2% in the first year and 5% in the second year. The proportion of disability among survivors in the first month ranged from 8% (95% CI, 3–15) for small artery disease ischemic stroke to 40% (95% CI, 30–52) for cardioembolic ischemic stroke patients. Conclusions Cardioembolic and undetermined with incomplete investigation ischemic stroke sub-types have a poor long-term prognosis. An alarming finding was that our patients with both small and large artery ischemic stroke had higher five-year mortality rates compared with subjects from high-income countries.

Background: Depicting the time trends of ischemic stroke subtypes may inform healthcare resource allocation on etiology-based stroke prevention and treatment. Aim: To reveal the evolving ischemic stroke subtypes from 2004 to 2018. Methods: We determined the stroke etiology of consecutive first-ever transient ischemic attack or ischemic stroke patients admitted to a regional hospital in Hong Kong from 2004 to 2018. We analyzed the age-standardized incidences and the 2-year recurrence rate of major ischemic stroke subtypes. Results: Among 6940 patients admitted from 2004 to 2018, age-standardized incidence of ischemic stroke declined from 187.0 to 127.4 per 100,000 population (p<0.001), driven by the decrease in large artery disease (43.0 to 9.67 per 100,000 population (p<0.001)) and small vessel disease (71.9 to 45.7 per 100,000 population (p<0.001)). Age-standardized incidence of cardioembolic stroke did not change significantly (p=0.2). Proportion of cardioembolic stroke increased from 20.4% in 2004-2006 to 29.3% in 2016-2018 (p<0.001). 2-year recurrence rate of intracranial atherothrombotic stroke reduced from 19.3% to 5.1% (p<0.001) with increased prescriptions of statin (p<0.001) and dual anti-platelet therapy (<0.001). In parallel with increased anticoagulation use across the study period (p<0.001), the 2-year recurrence of AF-related stroke reduced from 18.9% to 6% (p<0.001). Conclusion: Etiology-based risk factor control might have led to the diminishing stroke incidences related to atherosclerosis. To tackle the surge of AF-related strokes, arrhythmia screening, anticoagulation usage and mechanical thrombectomy service should be reinforced. Comparable preventive strategies might alleviate the enormous stroke burden in mainland China.
