Comparison of Risk Factor Control in the Year After Discharge for Ischemic Stroke Versus Acute Myocardial Infarction

Real-world analysis of two ischaemic stroke and TIA systolic blood pressure goals on 12-month mortality and recurrent vascular events

INTRODUCTION

Whether obtaining the more intensive goal systolic blood pressure (SBP) of <130 mm Hg, rather than a less intensive SBP goal of <140 mm Hg poststroke/transient ischaemic attack (TIA) is associated with incremental mortality and recurrent vascular event benefit is largely unexplored using real-world data. Lowering SBP excessively may result in poorer outcomes.

METHODS

This is a retrospective cohort study of 26 368 Veterans presenting to a Veterans Administration Medical Center (VAMC) with a stroke/TIA between October 2015 and July 2018. Patients were excluded from the study if they had missing or extreme BP values, receiving dialysis or palliative care, left against medical advice had a cancer diagnosis, were cared for in a VAMC enrolled in a stroke/TIA quality improvement initiative, died or had a cerebrovascular or cardiovascular event within 90 days after their index stroke/TIA. The analytical sample included 12 337 patients. Average SBP during 90 days after discharge was assessed in categories (≤105 mm Hg, 106-115 mm Hg, 116-130 mm Hg, 131-140 mm Hg and >140 mm Hg). Separate multivariable Cox proportional hazard regressions were used to examine the relationship between average SBP groups and time to: (1) mortality and (2) any recurrent vascular event, from 90 days to up to 365 days after discharge from the index emergency department visit or inpatient admission.

RESULTS

Compared with those with SBP>140 mm Hg, patients with SBP between 116 and 130 mm Hg had a significantly lower risk of recurrent stroke/TIA (HR 0.77, 95% CI 0.60 to 0.99) but not cardiovascular events. Patients with SBP lower than 105 mm Hg, compared with those with >140 mm Hg demonstrated a statistically significant higher risk of death (HR 2.07, 95% CI 1.43 to 3.00), but no statistical differences were found in other SBP groups.

DISCUSSION

Data support a more intensive SBP goal to prevent recurrent cerebrovascular events among stroke/TIA patients by 90 days poststroke/TIA compared with less intensive goal. Very low SBPs were associated with increased mortality risk.

Secondary Prevention in Patients With Stroke Versus Myocardial Infarction: Analysis of 2 National Cohorts

BACKGROUND

The implementation of preventive therapies among patients with stroke remains inadequately explored, especially when compared with patients with myocardial infarction (MI), despite sharing similar vascular risk profiles. We tested the hypothesis that participants with a history of stroke have a worse cardiovascular prevention profile in comparison to participants with MI.

METHODS AND RESULTS

In cross-sectional analyses within the UK Biobank and All of Us Research Program, involving 14 760 (9193 strokes, 5567 MIs) and 7315 (2948 strokes, 4367 MIs) participants, respectively, we evaluated cardiovascular prevention profiles assessing low-density lipoprotein (<100 mg/dL), blood pressure (systolic, <140 mm Hg; and diastolic, <90 mm Hg), statin and antiplatelet use, and a cardiovascular prevention score that required meeting at least 3 of these criteria. The results revealed that, within the UK Biobank, patients with stroke had significantly lower odds of meeting all the preventive criteria compared with patients with MI: low-density lipoprotein control (odds ratio [OR], 0.73 [95% CI, 0.68-0.78]; P<0.001), blood pressure control (OR, 0.63 [95% CI, 0.59-0.68]; P<0.001), statin use (OR, 0.45 [95% CI, 0.42-0.48]; P<0.001), antiplatelet therapy use (OR, 0.30 [95% CI, 0.27-0.32]; P<0.001), and cardiovascular prevention score (OR, 0.42 [95% CI, 0.39-0.45]; P<0.001). Similar patterns were observed in the All of Us Research Program, with significant differences across all comparisons (P<0.05), and further analysis suggested that the odds of having a good cardiovascular prevention score were influenced by race and ethnicity as well as neighborhood deprivation levels (interaction P<0.05 in both cases).

CONCLUSIONS

In 2 independent national cohorts, patients with stroke showed poorer cardiovascular prevention profiles and lower adherence to guideline-directed therapies compared with patients with MI. These findings underscore the need to explore the reasons behind the underuse of secondary prevention in vulnerable stroke survivors.

Effects of a Planned Web-Based Educational Intervention Based on the Health Belief Model for Patients With Ischemic Stroke in Promoting Secondary Prevention During the COVID-19 Lockdown in China: Quasi-Experimental Study

Background

Some common modified vascular risk factors remain poorly controlled among stroke survivors, and educational programs may help improve these conditions.

Objective

This study aimed to evaluate the effect of a planned web-based educational intervention based on the health belief model (HBM) in promoting secondary prevention among patients with ischemic stroke.

Methods

An evaluation-blinded quasi-experimental trial with a historical control group was conducted. Patients admitted from March to June 2020 were assigned to the historical control group, and patients admitted from July to October 2020 were assigned to the intervention group. The control group received routine health management. The intervention group received 6 additional sessions based on the HBM via Tencent Meeting, an audio and video conferencing application, within 3 months after discharge. Sessions were held every 2 weeks, with each session lasting approximately 40 minutes. These sessions were conducted in small groups, with about 8 to 10 people in each group. The primary outcomes were changes in blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), hemoglobin A1c (HbA1c), and the proportion of patients achieving the treatment target. The secondary outcomes were medication adherence, assessed with the Morisky Medicine Adherence Scale (MMAS), and disability, assessed with the modified Rankin scale.

Results

In total, 315 patients experiencing their first-ever stroke were analyzed. More patients in the intervention group had controlled BP (41.9% vs 28.4%; adjusted odds ratio [aOR] 1.93; P=.01), LDL-C (83.1% vs 67.7%; aOR 2.66; P=.001), and HbA1c (91.9% vs 83.9%; aOR: 3.37; P=.04) levels as well as a significant postintervention decrease in the systolic BP (adjusted β -3.94; P=.02), LDL-C (adjusted β -0.21; P=.008), and HbA1c (adjusted β -0.27; P<.001), compared with control groups. Significant between-group differences were observed in medication adherence (79.4% vs 63.2%; aOR 2.31; P=.002) but not in favorable functional outcomes.

Conclusions

A web-based education program based on the HBM may be more effective than current methods used to educate patients having strokes on optimal vascular risk factors and medication adherence.

How Would You Prevent Subsequent Strokes in This Patient? Grand Rounds Discussion From Beth Israel Deaconess Medical Center

Stroke is a major cause of morbidity, mortality, and disability. The American Heart Association/American Stroke Association recently published updated guidelines on secondary stroke prevention. In these rounds, 2 vascular neurologists use the case of Mr. S, a 75-year-old man with a history of 2 strokes, to discuss and debate questions in the guideline concerning intensity of atrial fibrillation monitoring in embolic stroke of undetermined source, diagnosis and management of moderate symptomatic carotid stenosis, and therapeutic strategies for recurrent embolic stroke of undetermined source in the setting of guideline-concordant therapy.

Lipid profiles and lifestyle habits of stroke survivors in the east coast region of peninsular Malaysia: Preliminary findings

Background: Stroke survivors are at high risk for recurrent cardiovascular events if no prevention strategies are undertaken. Aim: This study aimed to investigate the fasting serum lipid profiles and lifestyle habits in stroke survivors, and the factors associated with suboptimal lipid profiles. Methods: A cross-sectional retrospective study was conducted in three public hospitals in Malaysia. Stroke survivors' data regarding the socio-demographic characteristics, clinical profiles, fasting serum lipid profiles, dietary adherence, and physical activity levels were acquired. Binary logistic regression was used to examine the factors associated with suboptimal lipid goals. Results: A total of 104 stroke survivors were recruited from patients attending the neurology and rehabilitation departments. Only 22% of the stroke survivors attained the targeted low-density lipoprotein cholesterol level (LDL-C < 1.8 mmol/L). Meanwhile, more than two thirds of patients achieved the targeted total cholesterol, triglyceride, and high-density lipoprotein cholesterol goals. Patients with a longer stroke duration (Adjusted odds ratio, AOR 3.33, 95% confidence intervals, CI: 1.09, 10.13, p  =  0.034), elevated blood pressure (AOR 4.74, 95% CI: 1.65, 13.62, p  =  0.004), chronic kidney disease (AOR 3.30, 95% CI: 1.05, 10.34, p  =  0.041), abdominal obesity (AOR 3.14, 95% CI: 1.20, 8.21, p  =  0.020), excessive energy intake (AOR 2.72, 95% CI: 1.07, 6.91, p  =  0.036), and excessive saturated fatty acids intake (AOR 2.85, 95% CI: 1.02, 7.93, p  =  0.045) were significantly associated with suboptimal lipid profiles. Conclusion: The lipid goals attainment was low, particularly the LDL-C levels among Malaysian stroke survivors. Greater efforts are warranted to fully utilise the lipid-lowering therapy and the lifestyle changes in these high-risk patients.

Baseline Cardiovascular Risk Factor Control in Patients With Type 2 Diabetes and Coronary Disease Versus Stroke: Secondary Analysis of Cardiovascular Outcome Trials

BACKGROUND

Patients with type 2 diabetes (T2D) and cardiovascular disease are at increased risk for recurrent ischemic events. Cardiovascular risk factor control is vital for secondary prevention, but how this compares among individuals with different T2D macrovascular complications is unknown. We aimed to determine if there might be differences in risk factor control in patients with T2D with previous stroke versus coronary artery disease (CAD).

METHODS

Cross-sectional analyses were performed on 12 856 patients with T2D with prior history of stroke with or without CAD from 3 diabetes cardiovascular outcome trials: CARMELINA (The Cardiovascular and Renal Microvascular Outcome Study With Linagliptin), EMPA-REG OUTCOME (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients), and CAROLINA (The Cardiovascular Outcome Study of Linagliptin vs Glimepiride in Type 2 Diabetes). Risk factors at baseline assessed included dyslipidemia, hypertension, smoking, and current antiplatelet/anticoagulant therapy. Control, respectively, was defined as LDL (low-density lipoprotein)-C <100 mg/dL or statin use, systolic blood pressure <140 and diastolic blood pressure <90 mm Hg, not currently smoking, and use of an antiplatelet/anticoagulant medication. The odds ratio of 3 to 4 (or good) versus 0 to 2 (or suboptimal) risk factors controlled was analyzed by logistic regression models.

RESULTS

The odds for good versus suboptimal risk factor control in patients with CAD alone was higher than in those with stroke alone across all 3 trials odds ratios (95% CI): CARMELINA, 2.05 (1.67-2.51), EMPA-REG OUTCOME, 2.50 (2.10-2.99), and CAROLINA, 1.63 (1.21-2.20). The respective odds ratios were lower (and rendered nonsignificant in CAROLINA) when cardiovascular risk factor control in patients with both CAD and stroke were compared with those with stroke alone: CARMELINA, 1.45 (1.13-1.87); EMPA-REG OUTCOME, 1.62 (1.25-2.08); and CAROLINA, 1.16 (0.74-1.83).

CONCLUSIONS

In contemporary populations of patients with T2D, there was significant discordance in control of cardiovascular risk factors between patients with stroke versus CAD, with the former having less optimal control. The intermediate results in patients with both CAD and stroke suggest that these differences could be related at least in part to clinician factors.

Cardiovascular Events After Intracerebral Hemorrhage

Cardiovascular events after primary intracerebral hemorrhage (ICH) have emerged as a leading cause of poor functional outcomes and mortality during the long-term recovery after an ICH. These events encompass arterial ischemic events such as ischemic stroke and myocardial infarction, arterial hemorrhagic events that include recurrent ICH, and venous thrombotic events such as venous thromboembolism. The purpose of this review is to summarize the cardiovascular complications after ICH, epidemiology and associated risk factors, and their impact on ICH outcomes. Additionally, we will highlight possible pathophysiological mechanisms to explain the short- and long-term increased risks of ischemic and hemorrhagic events after ICH. Finally, we will highlight potential secondary stroke and venous thrombotic prevention strategies often not considered after ICH, balanced against the risk of ICH recurrence.

A 2-Year Longitudinal Study of Physical Activity and Cardiovascular Risk in Survivors of Stroke

OBJECTIVE

The purpose of this study was to explore associations between physical activity, cardiovascular risk factors, mobility, mood, fatigue, and cognition over 2 years following stroke rehabilitation discharge.

METHODS

In this longitudinal observational study, survivors of first-ever stroke were evaluated at rehabilitation discharge and 6, 12, and 24 months later. Moderate to vigorous physical activity (MVPA) duration (minutes/day) assessed with an electronic monitor was the primary outcome. Further outcomes included step count, the number and duration of MVPA and sedentary bouts, cardiovascular risk factors (eg, blood pressure, fasting lipid profile, body mass index [BMI]), gait speed and endurance, mood, fatigue, and cognition. Associations between physical activity and cardiovascular risk factors over time were assessed with random-effects regression modeling. Associations between baseline characteristics and physical activity at 2 years were explored using regression modeling.

RESULTS

Seventy-nine participants (68.4% men) with a mean age of 65 years (SD = 14) and a median gait speed of 1.2 m/s (interquartile range = 0.8 to 1.4) were included at baseline. Associations were found between higher physical activity (MVPA duration, number and duration of MVPA bouts) and lower BMI. Better gait speed, endurance, and cognition at baseline were associated with higher MVPA and step count at 2 years.

CONCLUSIONS

Duration and bouts of MVPA are associated with BMI. Increasing MVPA and bouts of MVPA may be a valuable treatment goal to reduce cardiovascular risk in survivors of stroke.

IMPACT

This 2-year study found that MVPA is associated with important cardiovascular risk factors in people who have survived stroke. Understanding these associations could be useful for developing effective treatments to prevent recurrent stroke.

LAY SUMMARY

Performing MVPA and accumulating in bouts of at least 10 minutes might be challenging, but it could be an important component of treatments to reduce cardiovascular risk after stroke.

Adherence to physical activity and cardiovascular recommendations during the 2years after stroke rehabilitation discharge

BACKGROUND

Objective measurement is essential to represent habitual physical activity. To date only one study has objectively measured physical activity for>12months after stroke.

OBJECTIVES

This study aimed to measure physical activity, cardiovascular risk factors, mobility, mood, fatigue and cognition during the 2years after rehabilitation discharge and to investigate whether stroke survivors meet physical activity and cardiovascular risk recommendations.

METHODS

This was a longitudinal observational study. Survivors of a first-ever stroke admitted to a large metropolitan rehabilitation hospital were recruited. Outcomes were measured at rehabilitation discharge and 6, 12 and 24months later. Outcomes were physical activity measured by the SenseWear Armband (e.g., moderate-vigorous physical activity, steps/day) and cardiovascular risk factors (e.g., blood pressure, fasting lipid profile and plasma glucose, waist circumference, body mass index), mobility, mood, fatigue and cognition. Changes over time were evaluated with random-effects regression modelling.

RESULTS

Participants (n=79, 33% female) had mean (SD) age of 65 (14) years and median gait speed 1.2m/s (interquartile range: 0.8-1.4) at baseline. We found no change in physical activity levels over time. Step count and time spent in bouts of moderate-vigorous physical activity remained low. Many participants achieved the recommended 30min of daily moderate-vigorous physical activity at baseline, but this was decreased at 2years (72% [57/79] versus 65% [37/57]). Adherence to cardiovascular recommendations decreased over time, notably for body mass index, plasma glucose and triglyceride levels. Waist circumference and body mass index increased at each time point relative to baseline (by a mean of 3.2cm and 1.2kg.m², respectively, at 2years, P<0.01).

CONCLUSIONS

This is the largest longitudinal study of objectively measured physical activity after stroke. Adherence to cardiovascular risk recommendations decreased over time post-stroke, and physical activity levels remained low. Stroke survivors may benefit from annual multidisciplinary reviews to identify increasing risk and initiate appropriate interventions.

Risk of Arterial Ischemic Events After Intracerebral Hemorrhage

Background and Purpose- The risk of arterial ischemic events after intracerebral hemorrhage (ICH) is poorly understood given the lack of a control group in prior studies. This study aimed to evaluate the risk of acute ischemic stroke and myocardial infarction (MI) among patients with and without ICH. Methods- We performed a retrospective cohort study using claims data from Medicare beneficiaries from 2008 to 2014. Our exposure was acute ICH, identified using validated International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis codes. Our primary outcome was a composite of acute ischemic stroke and MI, whereas secondary outcomes were ischemic stroke alone and MI alone. We used Cox regression analysis to compute hazard ratios during 1-month intervals after ICH. Sensitivity analyses entailed exclusion of patients with atrial fibrillation and valvular heart disease. Results- Among 1 760 439 Medicare beneficiaries, 5924 had ICH. The 1-year cumulative incidence of an arterial ischemic event was 5.7% (95% CI, 4.8-6.8) in patients with ICH and 1.8% (95% CI, 1.7-1.9) in patients without ICH. After adjusting for potential confounders, the risk of an arterial ischemic event remained significantly increased for the first 6 months after ICH and was especially high in the first month (hazard ratio, 6.7 [95% CI, 5.0-8.6]). In secondary analysis, the risk of ischemic stroke was increased in the first 6 months after ICH (hazard ratio, 6.1 [95% CI, 3.5-9.3]) but the risk of MI was not (hazard ratio, 1.6 [95% CI, 0.3-2.9]). In sensitivity analyses excluding patients with atrial fibrillation and valvular heart disease, the association between ICH and arterial ischemic events was similar to that of the primary analysis. Conclusions- In a large population-based cohort, we found that elderly patients with ICH had a substantially increased risk of ischemic stroke in the first 6 months after diagnosis. Further exploration of this risk is needed to determine optimal secondary prevention strategies for these patients.

Impact of different models of improvement of continuity of care on lipid control and the delay of visits to cardiology

Aims: To analyze the impact of implementing three different models of continuity of care on the delay of first visits to the cardiologist (management end point) and on LDL-cholesterol control rates among patients with atherosclerotic vascular disease (clinical end point). Methods: Observational, longitudinal and retrospective study of patients with cardiovascular disease and LDL-cholesterol ≥70 mg/dl attended in three hospitals (H1/H2/H3). In H1 and H2, a virtual system (telecardiology) was developed (in H1, internal audits and specific medical education were also performed). In H3 a cardiologist was integrated into the primary care center. Results: The delay of visits to cardiologist significantly improved from 66.5 ± 29.1 days to 34.1 ± 14.1 days (p < 0.001), as well as the intensification of lipid-lowering treatment and the achievement of lipid goals. LDL-cholesterol control rates were higher in H1 and the reduction of the delay of visits in H3. Conclusion: Continuity of care is associated with improvements in management and clinical end points.

Ambulatory blood pressure monitoring on admission in survivors of recent stroke entering inpatient rehabilitation

Arterial hypertension (AHT) is a major risk factor for stroke, yet blood pressure (BP) goals thereafter remain uncertain. Although additional prognostic value of 24-hour ambulant BP monitoring (ABPM) is acknowledged, its clinical impacts remain limited. We suspected that routine ABPM could identify characteristic circadian BP patterns in different brain lesion types, the knowledge of which might, in turn, be helpful in improving overall BP management in patients after stroke. In our study, we compared cardiovascular parameters derived from ABPM and traditional blood pressure measurements (TBPM) among 105 stroke survivors who entered our inpatient neuro-rehabilitation program. The mean age of mostly male (64.8%) patients was 71 ± 12 years. Ischemic strokes were predominant (75.2%). Despite normotensive systolic BP means in TBPM (133.5 ± 18.2 mmHg) and ABPM (24 h: 122.8 ± 14.7 mmHg), AHT persisted in up to 67.6% of all patients, with ABPM uncovering nocturnal systolic non- or reversed dipping in 89.5% and 53.3%, respectively. The latter was predominant (85.7%) in the hemorrhagic subgroup which also displayed lower daytime SBP than the ischemic one (ABPM: 117.1 ± 11.8 vs 124.7 ± 14.7 mmHg, p = 0.033). Further differences were present among distinct brain lesion types. Sufficient dippers were younger (58 ± 12 vs 75 ± 11 years, p < 0.001), but adjusting for age yielded no independent correlations. In spite of normotensive daytime BP measurements, ABPM detects latent AHT and insufficient nocturnal BP dipping after the acute phase of stroke. Further studies are needed to elucidate the role of increased nocturnal BP in patients after stroke.

Associations for BCO2, PCSK9, and TR1B1 Polymorphism and Lifestyle Factors with Ischemic Stroke: A Nested Case-Control Study

PURPOSE

To investigate associations for polymorphisms in β-carotene 9',10'-oxygenase (BCO2, rs10431036 and rs11214109), proprotein convertase subtilisin kexin type 9 (PCSK9, rs11583680), and tribbles pseudokinase 1 (TRIB1, rs17321515 and rs2954029), as well as lifestyle factors, with ischemic stroke (IS).

MATERIALS AND METHODS

This nested case-control study included 161 patients with IS and 483 matched control individuals. We collected medical reports, lifestyle details, and blood samples from individuals and used the PCR-ligase detection reaction method to genotype single nucleotide polymorphisms (SNPs).

RESULTS

The GA+AA genotype of rs10431036 (p<0.001) and rs17321515 (p=0.003), the CT+TT genotype of rs11214109 (p=0.005), and the TA+AA genotype of rs2954029 (p=0.006) in dominant models increased the risk of IS. In additive models, the GG genotype of rs17321515 (p=0.005) and the TT genotype of rs2954029 (p=0.008) increased the risk of IS. Adequate intake of fruits/vegetables reduced the risk of IS (p=0.005). Although there was no interaction between genes and fruits/vegetables, people with inadequate intake of fruits/vegetables who carried a risk genotype had a higher risk of IS than those only having inadequate fruits/vegetables intake or those only carrying a risk genotype. Also, the haplotypes AC, AT, and GT (comprising rs10431036 and rs11214109) and GT (comprising rs2954029 and rs17321515) were found to be associated with an increased risk of IS (p<0.05).

CONCLUSION

Polymorphisms in BCO2 and TRIB1 and fruits/vegetables intake were associated with IS. These results provide the theoretical basis for gene screening to prevent chronic cerebrovascular diseases.

Farmalarm

Background and Purpose- Risk factor control and treatment compliance in the following months after stroke are poor. We aim to validate a digital platform for smartphones to raise awareness among patients about the need to adopt healthy lifestyle, improve communication with medical staff, and treatment compliance. Methods- Farmalarm is an application (app) for smartphones designed to increase stroke awareness by medication alerts and compliance control, chat communication with medical staff, didactic video files, exercise monitoring. Patients with stroke discharged home were screened for participation and divided into groups: to follow the FARMALARM program for 3 to 4 weeks or standard of care follow-up. We determined achievement of risk factor control goals at 90 days. Results- From August 2015 to December 2016, from the 457 patients discharged home, 159 (34.8%) were included: Farmalarm (n=107); age 57±12, Control (n=52), age 59±10; without significant differences in baseline characteristics between groups. At 90 days, knowledge of vascular risk factors was higher in FARMALARM group (86.0% versus 69.2%, P<0.01). The rate of patients with diabetes mellitus (83.2% versus 63.5%, P<0.01) and hypercholesterolemia (80.3% versus 63.5%, P=0.03) under control and the rate of patients with 4 out of 4 risk factors under control was higher in FARMALARM group (50.4% versus 30.7%, P=0.02). A regression model showed that the use of Farmalarm was independently associated with all risk factors under control at 90 days (odds ratio, 2.3; 95% CI, 1.14-4.6; P=0.02). Conclusions- In patients with stroke discharged home, the use of mobile apps to monitor medication compliance and increase stroke awareness is feasible and seems to improve the control of vascular risk factors.

The Clinical Importance of the Plasma Atherogenic Index, Other Lipid Indexes, and Urinary Sodium and Potassium Excretion in Patients with Stroke

OBJECTIVE

Cardiovascular complications are still the primary reason for high mortality rates worldwide. The determination of risk factors is important to prevent stroke. The aim of the present study was to analyze the importance of serum lipid indexes and urinary sodium (Na)/potassium (K) excretion in patients with stroke together with sex differences.

MATERIALS AND METHODS

A total of 50 (28 male and 22 female, mean age 65.9±14.6 years) patients with acute stroke were included in the study group, and 32 body mass index-matched healthy subjects were included in the control group. Lipid profiles [(cholesterol, triglyceride, very low-density lipoprotein, low-density lipoprotein, and high-density lipoprotein (HDL)], serum creatinine (Cre), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and Na, K, and Cre excretion in spot urine samples of the patients were recorded.

RESULTS

Systolic blood pressure (p=0.021), ESR (p=0.044), and CRP (p=0.042) were significantly higher in all patients in the stroke group; urinary Tanaka (K) (p=0.033), Kawazaki (K) (p=0.028), urinary spot Cre (p=0.012), and Na excretion (p=0.036) levels were found to be significantly lower in only male patients with stroke. The mean plasma atherogenic indexes were 0.57±0.24 in the study (stroke) group and 0.54±0.22 in the control group (p=0.61). Other lipid indexes, such as Castelli's risk index (CRI)-I (p=0.29), CRI-II (p=0.24), atherogenic coefficient (p=0.29), and non-HDL cholesterol (p=0.69), were not statistically different from the controls.

CONCLUSION

Urinary Na, K, and Cre excretion was significantly lower in male patients with stroke, and acute phase reactants were significantly higher in the entire stroke group than in controls. These parameters can be used as auxiliary biomarkers in the risk assessment of stroke.

Opportunities and challenges in secondary stroke prevention: a mixed methods study

Purpose: To describe control of risk factors after stroke from the perspectives of the stroke survivor, the family, and healthcare professionals.Materials and methods: A mixed methods design was used, undertaken in two phases: i) qualitative study using focus group methodology to explore secondary stroke prevention and ii) survey of stroke survivors about use of technology and self-management of blood pressure (BP).Results: From the eight focus groups (n = 33), three themes were identified: i) stroke is a wake-up call to do the right things; ii) challenges to doing the right things; and iii) role of technology in helping you to do the right things. Among survey respondents (n = 82), most participants reported mobile phone ownership (93%), mostly smartphones (66%), and >80% identified a greater role for technology in supporting management of risk factors. Participants who reported monitoring BP at home were significantly more likely to know their target BP than those not monitoring at home (83 vs. 42%; p < 0.001) and more adherent with medications (78 vs. 52%; p = 0.016).Conclusions: These findings highlight the ongoing challenges with achieving risk factor control after stroke and the potential to utilise health information technology to engage stroke survivors in self-management of their risk factors.Implications for rehabilitationClinicians should be knowledgeable of the challenges that stroke survivors face in managing their risk factors after stroke and the role that they can play in providing tailored education.BP continues to be poorly controlled after stroke and there is opportunity for improvement.Stroke survivors and their families are receptive to using health information technology to support their risk factor control.Rehabilitation clinicians have an opportunity to incorporate different aspects of health information technology into their practice to support self-management of risk factors.
