Family History and Functional Outcome in Korean Stroke Patients: A Preliminary Study

Family History is Related to High Risk of Recurrent Events after Ischemic Stroke or Transient Ischemic Attack

OBJECTIVE

Prior data suggest paternal or sibling stroke was associated with increased risk of offspring stroke. Whether family history of cardiovascular disease (FHc) predicts risk of stroke recurrence remains unclear, we aim to determine this issue on patients with ischemic stroke (IS) or transient ischemic attack (TIA).

MATERIALS AND METHODS

This is a post hoc analysis based on the Third China National Stroke Registry III. IS/TIA patients with data of FHc status were included. FHc was defined as family history of coronary heart disease (CHD) or stroke among first-degree relatives (include parents, children, and siblings (same parents)). Cox proportional hazards regression models were performed to assess the association between FHc and recurrent events at 1 year follow-up.

RESULTS

Totally 14,208 patients with verified FHc status were included, 4,454 (31.3%) were female and the median (IQR) age was 62.0 (54.0, 70.0) years. Of these, 294 (2.1%), 726 (5.1%) and 1936 (13.6%) had family history of both CHD and stroke, family history of CHD, and family history of stroke only, respectively. Using multivariable Cox models adjusted for age, sex, and vascular risk factors, we found that patients with FHc experienced higher risk of stroke recurrence (HR=1.151, 95%CI=1.000-1.324) and combined vascular events (HR=1.186, 95%CI=1.036-1.358) at 1 year compared with those without FHc. In sensitivity analysis on patients who received primary secondary prevention treatment of antiplatelet and statins, the association persisted.

CONCLUSIONS

FHc is associated with increased risk of stroke recurrence even under primary secondary prevention treatment.

The effect of premorbid features on post-stroke rehabilitation outcome

Background: A wide variety of factors influence stroke prognosis, including age, stroke severity, stroke mechanism, infarct location, comorbid conditions, clinical findings, and related complications. The aim of this study was to detect the prognostic determinants in patients with acute stroke for guiding rehabilitation. Methods: Patients with ischemic acute stroke were included in the study. Patients' age, sex, education level, and marital status, premorbid personality traits, comorbidities such as current smoking status and alcohol consumption, regular exercise habits, and sleeping disorder were recorded. Motor assessment and daily activity skills were evaluated according to the Brunnstrom staging and Functional Independence Measure (FIM), respectively. Results: A total of 85 patients were studied. All patients' motor and functional stages were significantly improved with the rehabilitation. The improvements in the upper extremity motor levels were less in whom over 76 years and smokers, in patients who had 4 and more comorbidities and sleep disorders. The functional improvement was less in whom over 76 years and men, and in patients who had 4 and more comorbidities and sleep disorders. Conclusion: The significant post-stroke predictor of insufficiency in functioning was having 4 or more risk factors.

The impact of physical function on participation in the first year post-stroke

OBJECTIVES

Studies have investigated predictors of participation and showed that fewer depressive symptoms, physical independence, and age could predict the level of participation after stroke. Association between self-assessed functions and perceived levels of participation over time is not yet known. The aim of this study was to investigate perceptions of participation and how this related to background characteristics and self-assessed rehabilitation outcomes, at 1, 6, and 12 months post-stroke.

MATERIALS AND METHODS

To capture experienced functioning and participation, a self-assessment questionnaire, the Stroke Impact Scale (SIS), was used at 1, 6, and 12 months post-stroke. Possible variables with impact on perceived participation were investigated with logistic regression: perceived physical functions, memory and thinking, emotion and communication (SIS), as well as background characteristics. In addition, directions, distributions, and strength of correlations between each independent variable and the participation domain were analyzed using scatterplots.

RESULTS

Participation scores were widely distributed during the first year post-stroke. Significant associations were only found between perceived Physical score and participation during the first year post-stroke (1 month, n=92, P<.001; 6 months, n=79, P=.001; 12 months, n=78, P=.002). A moderate-to-high participation score was observed in combination with a high level of perceived emotional health and cognitive skills, at 1, 6, and 12 months.

CONCLUSIONS

The findings indicate that to improve participation during the first year post-stroke, physical functioning as well as emotional and cognitive health can be important areas of concern when forming rehabilitation interventions.
