Abstract BACKGROUND High blood pressure variability (BPV) is associated with recurrent stroke. We investigated the association between BPV, new ischemic lesions (NILs), and white matter lesion (WML) growth in patients with ischemic stroke due to intracranial atherosclerosis (ICAS). METHODS This study was performed as a post-hoc analysis of the STABLE-ICAS trial, which enrolled subacute ischemic stroke patients with symptomatic ICAS (>50% stenosis) and hypertension. BPV was measured at the office (visit by visit) and at home (day by day). Patients were divided into 3 groups (tertiles) according to their home BPV. WML growth and the occurrence of NILs were compared among the 3 groups. Multivariable analyses were performed to identify the independent risk factors of WML growth and NILs. RESULTS Of the 111 enrolled patients, 69 patients (67.6%) demonstrated WML growth and 15 patients (13.7%) had NILs. Patients with higher BPV demonstrated a more WML growth (50% vs. 61.8% vs. 83.8; P = 0.02, by tertiles) and more NILs (5.4% vs. 5.4% vs. 29.7%; P = 0.002, by tertiles). In multivariable analyses, old age [odds ratio (OR) = 1.052 (95% confidence interval (CI) = 1.005–1.101); P = 0.03] and home BPV [OR = 1.149 (95% CI = 1.013–1.304); P = 0.02] were independently associated with WML growth. Low mean diastolic blood pressure [OR = 0.913 (95% CI = 0.874–0.984); P = 0.02] and high home BPV [OR = 1.287 (95% CI = 1.086–1.526); P = 0.004] were independently associated with NILs at follow-up. CONCLUSIONS High BPV is associated with WML growth and NIL in ischemic stroke patients with symptomatic ICAS. BPV monitoring at home may be helpful.

Background: Hypertension is considered major risk factor for incidence of ischemic stroke, controlling blood pressure reduces this risk, the relationship of uncontrolled blood pressure and stroke outcomes is complex, post stroke uncontrolled blood pressure remains one of the major contributing factors for stroke recurrence and mortality, in our study we studied the long term effects of uncontrolled hypertension in modern health care setting. Methodology: Patients in the study were admitted to the neurology department at KFSH-D between March 2015- August 2019, we included 102 acute ischemic stroke patients whom had hypertension, all patients had follow up appointments at stroke clinic a minimum of 2 visits over 4 years. We retrospectively compared blood pressure data from stroke patients with recurrent ischemic stroke events vs. patients with initial stroke event, and recurrent stroke, also we studied blood pressure readings for different stroke severity groups, patients who had severe stroke with mRS>4, compared to milder stroke group of mRS<4. Results: We found 48 patients identified with recurrent stroke event, those with uncontrolled hypertension had significantly higher stroke recurrence events (P=0.002), despite acute stroke treatment, patients who had history of uncontrolled hypertension were found to have more severe stroke deficits than those who had controlled blood pressure (P=0.029). We found significant difference in the long term stroke clinical outcomes between patients who had uncontrolled blood pressure and patients who had controlled blood pressure recordings within the same hospital setting (P=0.064). Conclusion: Based on our findings, uncontrolled hypertension was associated with higher risk of stroke recurrence, it also increased susceptibility to worse stroke clinical outcomes up to 1 year after initial stroke event, which deserved further close attention and better blood pressure control.

Background: Variability in blood pressure is a predictor of stroke severity and causes of poor functional outcome. Blood pressure variability is one of the main predictor of the prognosis acute ischemic stroke. Blood pressure variability were independently and linearly associated with the development of early neurologic deterioration (END) in acute ischemic stroke Objective: To determine the association between blood pressure variability and END in acute ischemic stroke patients. Method: This study uses a cross sectional design. Sampling was conducted at H. Adam Malik General Hospital Medan. Samples were taken as many as 40 subjects consecutively. Blood pressure checks were perform every hour for 72 hours then an assessment of the National Institute of Health Stroke Scale (NIHSS) score at admission and the third day of treatment. Data analysis used fisher’s exact test. Results: The demographic characteristics of the study subjects were an average age of 56-<71 years, high school education level, housewife occupation and Batak ethnicity. The mean of maximum systolic blood pressure (SBP) was 151±12.16 mmHg, minimum SBP 123.15±18 mmHg, delta SBP 25.35±10.66 mmHg, maximum diastolic blood pressure (DBP) 79.7±6.01 mmHg, minimum DBP 61.77±7.32 mmHg and delta DBP 17.97±8.48 mmHg. The NIHSS day 1 score had an average of 9.55±6.73, the NIHSS day 3 score was 11.25±7.93. Most subjects experienced END. There is a significant relationship between blood pressure variability and END with a p of 0.03 (p<0.05). Conclusion: There is a significant relationship between blood pressure variability and END in patients with acute ischemic stroke.

Abstract Background We aim to document the long-term outcomes of ischemic stroke patients and explore the potential risk factors for recurrent cardiovascular events and all-cause mortality in primary care. Methods A retrospective cohort study performed at two general out-patient clinics (GOPCs) under Hospital Authority (HA) in Hong Kong (HK). Ischemic stroke patients with at least two consecutive follow-up visits during the recruitment period (1/1–30/6/2010) were included. Patients were followed up regularly till the date of recurrent stroke, cardiovascular event, death or 31/12/2018. The primary outcome was the occurrence of recurrent cerebrovascular event including transient ischemic stroke (TIA), ischemic stroke or hemorrhagic stroke. The secondary outcomes were all-cause mortality and coronary artery disease (CAD). We fit cox proportional hazard model adjusting death as competing risk factor to estimate the cause-specific hazard ratio (csHR). Results A total of 466 patients (mean age, 71.5 years) were included. During a median follow-up period of 8.7 years, 158 patients (33.9%) died. Eighty patients (17.2%) had recurrent stroke and 57 (12.2%) patients developed CAD. Age was an independent risk factor for recurrent stroke, CAD and death. Statin therapy at baseline had a protective effect for recurrent stroke (csHR = 0.476; 95% confidence interval [CI] 0.285–0.796, P = 0.005) after adjusting death as a competing risk factor and all-cause mortality (HR = 0.693, 95% CI 0.486–0.968, P = 0.043). In addition, female sex, antiplatelet and a higher diastolic blood pressure (DBP) at baseline were also independent predictors for survival. Conclusions Long term prognosis of ischemic stroke patients in primary care is favorable. Use of statin was associated with a significant decrease in stroke recurrence and mortality. Patients who died had a significant lower DBP at baseline, highlighted the need to consider both systolic and diastolic blood pressure in our daily practice.

Background: Blood pressure variability (BPV) is associated with target organ damage progression and increased cardiovascular events, including stroke. The aim of this study was to evaluate the associations between short-term BPV during acute periods and recanalization degree, early neurological deterioration (END) occurrence, and functional outcomes in acute ischemic stroke patients who had undergone intra-arterial thrombectomy (IAT). Methods: We retrospectively analyzed 303 patients with large vessel occlusive stroke who underwent IAT. The following BPV parameters, measured over 24 and 48 h after IAT, were compared: the mean, SD, coefficient of variation (CV), variation independent of the mean (VIM) for both the systolic BP (SBP) and diastolic BP, and the proportion of nocturnal SBP risers. Results: BPV parameters decreased with higher recanalization degree. The mean SBP (SBPmean) over 24 and 48 h after IAT, and the SD of SBP (SBPSD), CV of SBP (SBPCV), and VIM of SBP (SBPVIM) during the 48 h following the procedure had significant associations with recanalization degree. Patients with END had higher BPV than that of those without END, and the difference was more evident for incomplete recanalization. Increased BPV was associated with a shift toward poor functional outcome at 3 months after adjustment, including recanalization degree (OR range for significant parameters, 1.26–1.64, p = 0.006 for 48 h SBPmean, p = 0.003 for 48 h SBPCV, otherwise p < 0.002). Conclusions: Short-term BPV over 24 and 48 h after IAT in acute ischemic stroke patients was related to recanalization degree, and END occurrence, and may be an independent predictor of clinical outcome.

Background: Stroke is the third leading cause of death in adult population throughout the world and is the most common cause of severe adult physical disability. It is increasing at an alarming rate in Asia including Bangladesh. The effect of recurrent stroke is devastating on patient as it is the main reason of mortality and morbidity among patients. Methods: A longitudinal, observational study was conducted from April 2018 to October 2018 in the department of Neurology, Bangabandhu Sheikh Mujib Medical University, Dhaka. All the patients of first ever ischemic stroke confirmed by neuroimaging (CT scan of head / MRI of brain), meeting the inclusion and exclusion criteria were included in the study. Our study was performed with sixty stroke patients. We followed up patient up to 90 days and observed for stroke recurrence. Results: Present study showed among the 60 stroke patients, only 4 (6.67%) suffered from stroke recurrence within 3 months. In our study, uncontrolled systolic blood pressure (p=0.04), uncontrolled diastolic blood pressure (p=0.027), dyslipidaemia (p=0.001), smoking (p=0.0003) and antiplatelet discontinuation (p=0.0001) were significantly associated with stroke recurrence whereas uncontrolled diabetes mellitus (p=0.46) and presence of atrial fibrillation (p=0.057) had no significant association. Conclusion: Smoking, hypercholesterolemia, uncontrolled systolic &/or diastolic blood pressure and discontinuation of antiplatelet therapy were significantly associated with stroke recurrence in this population. Therefore, early identification and control of these risk factors are essential to prevent recurrent stroke, thereby decrease morbidity and mortality.

Background: High blood pressure (BP) is a well recognized risk factor for ischemic stroke, and aggressive BP control is critical for secondary stroke prevention. However, hypertensive (HTN) outpatients are often found to have uncontrolled BP, in part due to poor compliance with daily at-home BP monitoring and consequent poor medication adherence. Here, we explore the association of patient home BP self-monitoring compliance with stroke recurrence. Method: Ischemic stroke patients with pre-existing HTN were prospectively recruited in accordance with IRB protocol for this observational study. All patients were trained on BP self-monitoring as per standard of care, and were asked to monitor BP at home daily consistently for 2 weeks. BP monitoring compliance, per completion of BP log, was assessed at each follow-up clinical visit by an investigator blinded to patient outcome. Stroke recurrence was followed for 5 years and independently adjudicated by two vascular neurologists. Result: In a total of 219 patients, only 36 patients (16.4%) were compliant in completing the home BP log as instructed. The compliant and non-compliant groups showed no baseline difference and no medication usage difference (p>0.05) (Table 1). Compliance with at-home BP monitoring was associated with well controlled systolic (p<0.001) and diastolic BP (p<0.001). Of note, 30 patients (16.4%) had recurrent strokes in the non-compliant group, while there were no recurrent strokes in the compliant group. BP self-monitoring compliance is associated with reduced incidence of stroke recurrence (p=0.030) and the significance remains robust after adjusting for multiple confounders (p=0.029) (Table 2). Conclusion: Regular home BP monitoring is associated with lower risk of stroke recurrence in HTN stroke patients. Study in expanded patient cohort is ongoing to leverage technology for better home BP monitoring and to create incentives for compliant behavior for better secondary stroke prevention.
