“…These findings were the same as those in middle-aged and old stroke [19,20]. The 40 cases of young IS studied by Khan et al, included 40% TACI, 12.5% PACI, 42.5% LACI and 5% POCI, in which there were more cases of major stroke (TACI) [22]. However, our study had more cases of PACI and LACI and fewer numbers of TACI, which suggested a greater prevalence of moderate and minor stroke among the local young people, and thus a better prognosis.…”

Background: The morbidity and mortality rates in young Chinese stroke patients have increased, and the appropriate classification of stroke is very important to identifying the cause, pathogenesis, severity, outcome, and preventive and therapeutic strategies. This study sought to analyse the young stroke subtype in a coastal city Zhuhai of southern China. Methods: Hospitalised young stroke patients in the two largest local hospitals were retrospectively analysed from July 2002 to July 2009. The percentage of every stroke subtype was calculated. Results: A total of 416 young stroke patients (age 18-45 years) were included. There were 225 (54.1%) cases of ischemic stroke (IS), 145 (34.9%) cases of intracerebral haemorrhage (ICH), 38 (9.1%) cases of subarachnoid haemorrhage (SAH), and 8 (1.9%) cases of mixed stroke (MS). Cases of IS were divided into four groups using the OCSP criteria: 15 (6.7%) total anterior circulation infarcts (TACI), 117 (52.0%) partial anterior circulation infarcts (PACI), 61 (27.1%) lacunar infarcts (LACI ), and 32 (14.2%) posterior circulation infarcts (POCI). Cases of IS were divided into five groups using the TOAST criteria: 14 (6.2%) cases of large-artery atherosclerosis (LAA), 15 (6.7%) cases of cardioembolism (CE), 108 (48 %) cases of small-artery occlusion (SAO), 16 (7.1%) cases of stroke of other determined aetiologies (SOE), and 72 (32%) cases of stroke of undetermined aetiology (SUE). Conclusions:The results suggested that within the locality, the majority of cases of young stroke were IS and ICH, and the minority were SAH and MS; additionally, the most common IS subtypes were PACI, LACI or SAO and SUE, which could contribute to the local prevention and control of stroke.

“…The ratios of LACI seem to be broadly similar around the world, except for Argentina, Australia and Switzerland according to Shinohara's study [25]. However, our and other's study indicated the dissimilar ratios of LACI in young IS [21,22].…”

“…However, epidemiological findings from French, Korean and some Arab publications also report a higher prevalence of LA, reaching 35.8% (Bejot et al, 2008), 36% (Kim and Kim, 2014) and 38.1% (Deleu et al, 2011) of all ischemic subtypes, respectively. Conversely, the CE subtype is more frequently reported in Western countries (Schulz and Rothwell, 2003;Ueshima et al, 2008;Ihle-Hansen et al, 2012;Kim and Kim, 2014), whereas the SV subtype is reported with high prevalence in Asian and Arab countries (Al-Shammri et al, 2003;Bahou et al, 2004;Khan et al, 2008;Turin et al, 2010). Furthermore, the present study shows a significant association between ischemic stroke subtypes and specific risk factors.…”

A retrospective analysis of 254 acute stroke cases admitted to two university hospitals in Beirut: classification and associated factors

SummaryLebanon is a developing country where the prevalence of stroke subtypes and their correlation with risk factors have not been studied, even though stroke management is an ongoing major national healthcare challenge. In a retrospective study conducted in two university hospitals, data were collected on all stroke cases admitted in 2012 and 2013. Ischemic strokes were then classified according to a modified TOAST classification. A total of 254 inpatients (mean age 68.41 years ±13.34, 55.1% males) was included in the study; of these, 15% had had a hemorrhagic stroke and was therefore excluded. Conversely to findings from studies in other Arab and Asian countries, where small vessel disease is the most frequent subtype, our study showed a predominance of large artery atherosclerosis (53.5%) which, in comparison with other subtypes, was found to be associated with dyslipidemia (OR= 3.82,]; p=0.001). Cardioembolic stroke and small vessel disease were found to be positively associated with aging and living in Beirut, respectively. Larger studies are needed to explain these findings.

“…With 80% of its population being males, the average age of stroke patients is relatively low when compared with patients globally, and majority of the patients present with small vessel diseases and have a history of diabetes mellitus. 16 We compared the rates of complications, LOS in the hospital, and mortality rates in patients admitted to the hospital before and after implementation of the stroke protocols and establishment of the SW.…”

Background and Purpose— Usefulness of multidisciplinary stroke units in acute stroke patients is well established. There is extensive western literature on usefulness of stroke units in outcome, but limited evidence from the rest of the world. We aim to evaluate the impact of establishing a stroke unit on outcome in patients presenting to a tertiary care facility. Methods— This is a retrospective study of 1003 patients with acute stroke admitted to Hamad General Hospital, Qatar, between January 2014 and February 2015. Patients directly admitted to intensive care unit (132) were excluded. We compared outcomes of pre- and poststroke ward (SW) establishment and in SW patients versus those of general medical wards. Results— Before the establishment of the SW, 175 patients were admitted to the hospital. From April 2014 to February 2015, 696 patients were admitted (SW, 545; medical ward, 151). There was a significant reduction in length of stay from 14.7±27.7 to 6.2±20.2 days ( P =0.0001) and incidence of complications (23.6% versus 6.4%, P =0.0001) after implementation of stroke-specific protocols. Prognosis at discharge (modified Rankin Scale 0–2 in 56.0% versus 70.4%, P =0.001) and at 90 days (modified Rankin Scale 0–2 in 70.6% versus 95.0%, P =0.001) also significantly improved. Compared with medical ward patients, outcome was significantly better in SW patients with fewer complications (10.9% versus 5.0%, P =0.013) and shorter length of stay (8.9±30.7 versus 5.4±16.1 days, P =0.05). Conclusions— Establishing a distinct SW is essential for achieving full benefits of stroke protocols implementation. SW patients have significantly fewer complications and better prognosis when compared with patients in medical wards.
