Predictors of short-term mortality after acute stroke in East Azerbaijan province, 2014

Abstract

Introduction: Stroke is one of the important causes of death and disability in Iran. This study aimed to examine the factors influencing the short-term mortality of stroke in Northwest of Iran. Methods: Study population were all patients with confirming the diagnosis of the first-ever stroke who were hospitalized in two referral teaching hospitals from October 2013 to March 2015. They were followed up to 30 days after onset of stroke. A neurology year three resident was responsible for extracting the clinical data and assessment of stroke severity on admission using National Institute of Health Stroke Scale (NIHSS), and information about risk factors and socio-demographic factors were collected using face to face interview. Data were analysed using Cox proportional regression by STATA software version 14. Results: A total of 1036 consecutive patients with first-ever stroke were included in this study. Of them, 228 patients (22%) died within 30 days after stroke accordance. Advanced age was significantly associated with a hazard for early mortality (HR=1.05 95% CI 1.09–1.04), the inverse was true for education level; mortality decreased as the education level increased; it was 25.7 percent among illiterate and 14.3 among patients with higher education. The NIHSS score on admission for 30-days mortality and hemorrhagic stroke were associated with HR=1.11 (95% CI 1.09–1.13) and HR= 1.65 (95% CI 1.15–2.36) respectively. Conclusion: Advanced age, stroke subtype and high NIHSS score are the independent predictors of early mortality in this study. This provides important implications for the clinicians to target the high-risk patients for the specific therapies and management strategies.

Epidemiology of Mortality From Cerebrovascular Accident in Patients Admitted to Sina (Farshchian) Educational-Medical Hospital of Hamadan in 2018-2019

“…In addition, the findings of Shamshirgaran et al indicated that 13.2% of deceased people due to stroke had a positive family history of stroke. 26 Additionally, in a 5-year research study of stroke mortality, Lambert et al concluded that 11.1% of deceased people had a family history of stroke, 27 which contradicts the results of the present study. The reason for this conflict in findings may be the illiteracy of the majority of the examined patients and their lack of awareness of having a family history of stroke.…”

“…This provides important implications for the clinicians to target the high-risk patients for the specific therapies and management strategies. 7 We found that in expired patients, mean NIHSS score was 21.6 ± 5.08 which was remarkably high and statistically significant.…”

Mortality Rate of Acute Stroke in Iran: A Systematic Review and Meta-Analysis

“…The incorporated studies were from 1998 to 2018, and only 13 provinces had at least one eligible study. Based on the geographical location of the province, out of 28 studies included, six were in Khorasan Razavi [22][23][24][25][26][27], 6 in East Azerbaijan [14,16,17,[28][29][30], 3 in Isfahan [31][32][33], 2 in Tehran [34,35], 2 in Qom [13,36], and 2 in Ardabil [34,35,37,38]. Guilan [39], Kermanshah [40], South Khorasan [41], Mazandaran [42], Fars [15], Urmia [43], and Zahedan [44] Semnan [45] each had 1 study.…”

“…Stroke mortality can be an excellent indicator of stroke care and control. Several studies have been conducted to estimate the mortality rate of stroke in hospitals, including 30 days post-stroke [14,15], six months post-stroke [16], and long periods with different sample sizes and different follow-up lengths in several provinces of Iran [17]. Identification of mortality predictors at the time of hospitalization can be beneficial in reducing post-stroke mortality rates.…”
