Mortalité à long terme des survivants d'accidents vasculaires cérébraux ischémiques à Bobo Dioulasso, Burkina Faso / Long-term mortality of ischaemic stroke survivors in Bobo-Dioulasso, Burkina Faso

Contexte et objectif. La survie à long terme des accidents vasculaires cérébraux ischémiques (AVCI) reste un défi majeur. L'objectif de ce travail était d'analyser la mortalité à long terme des survivants d'AVCI. Méthodes. Il s'est agi d'une cohorte rétrospective portant sur les patients hospitalisés du 1er janvier 2017 au 31 décembre 2019, sortis vivants du service de neurologie au Centre Hospitalier Universitaire Sourô Sanou de Bobo-Dioulasso après un AVCI. Nous avons recouru aux méthodes de Kaplan Meier et la regression de Cox pour décrire respectivement la survie et les prédicteurs de la mortalité. Résultats. Au total, 87 patients dossiers ont été colligés. L'âge moyen était de 61,2 ans (±13,7). Le sex-ratio M/F était de 1,23/1. L'hypertension artérielle était le principal facteur de risque cardiovasculaire (65,5 %). Les antécédents de cardiopathies étaient présents chez 6 patients. La conscience était normale chez 82 patients et les complications de décubitus ont été observées chez 20 patients au cours de l'hospitalisation. La durée moyenne d'hospitalisation était de 15,8 jours. La mortalité cumulée en post hospitalisation était de 40,2 % à 4 ans. Les facteurs prédictifs de la mortalité étaient l'âge > 60 ans (p=0,008; HRa= 3,05 ; IC 95 % : 1,33-6,99), le score de Glasgow>9 (p<0,001; HRa = 0,09; IC 95 % : 0,02-0,31) et l'absence de complication de décubitus (p=0,009; HRa = 0,34; IC95 % : 0,15-0,76). Conclusion. Dans ce contexte, la mortalité à long terme des AVCI est élevée. Le renforcement du suivi vis-à-vis des groupes spécifiques pourrait contribuer à réduire considérablement cette mortalité à long terme.

Context and objective. Long-term survival from ischaemic stroke remains a major challenge. The aim of this study was to analyse the long-term mortality of stroke survivors at the Sourô Sanou University Hospital in Bobo-Dioulasso. Methods. This was a retrospective cohort of hospitalized patients from January 1, 2017 to December 31, 2019, discharged alive from the neurology service after ischaemic stroke. We used Kaplan Meier and Cox regression methods to describe survival and predictors of mortality, respectively. Results. A total of 87 patients were included in this study. The mean age was 61.2 years (±13.7). The sex ratio M/F was 1.23. Hypertension was the main cardiovascular risk factor (65.5%). A history of heart disease was present in 6 patients (6.9%). Consciousness was normal in 82 patients (94.2%) and decubitus complications were observed in 20 patients (23%) during hospitalisation. The average length of hospital stay was 15.8 days. Cumulative post-hospital mortality was 40.2% at 4 years. Factors predictive of mortality were age >60 years (p=0.008; aHR= 3.05; 95%CI: 1.33-6.99), Glasgow score>9 (p<0.001; aHR = 0.09; 95% CI: 0.02-0.31) and absence of decubitus complication (p=0.009; aHR = 0.34; 95%CI: 0.15-0.76). Conclusion. In this context, long-term mortality in ischaemic stroke is high. Closer monitoring of specific groups could help to reduce considerably this long-term mortality.

Profil épidémiologique, clinique et évolutif des personnes âgées admis en réanimation au CHU de Cocody (Abidjan-Côte-d'Ivoire / Epidemiological, clinical and evolutionary profile of elderly people admitted to the intensive care unit at the CHU of Cocody (Abidjan-Côte d'Ivoire)

Contexte et objectif. La croissance en nombre et en proportion des personnes âgées implique des conséquences sanitaires. La présente étude avait pour objectifs de décrire le profil clinique et évolutif du sujet âgé admis en réanimation et de rechercher des facteurs associés à la mortalité en réanimation polyvalente. Méthodes. C'était une étude documentaire descriptive, de janvier 2019 à décembre 2020, dans le service de réanimation polyvalente du CHU de Cocody. Résultats. La prévalence annuelle des sujets âgés était de 8,6 %. Leur âge moyen était de 70,5 ans ± 9,4 ans (60-92), le sex ratio de 0,8. Les patients en activité professionnelle étaient de 17,5 % et la majorité vivaient en zone urbaine. Les antécédents médicaux étaient surtout l'HTA et le diabète. Les motifs d'admission fréquemment étaient le trouble de la conscience (69,2 %), la détresse respiratoire (12,5 %). Le délai d'admission était de à 7 jours ( , %). Les diagnostics retenus étaient dominés par l'AVC ischémique (24,2 %), l'acidocétose diabétique (17,5 %). Le taux de décès était de 65,8 %. L'âge, le type de pathologie et la durée d'hospitalisation étaient des facteurs pronostiques significativement liés à la mortalité. Conclusion. Le vieillissement de la population a un impact majeur sur le recrutement des patients en réanimation, nécessitant la collaboration multidisciplinaire.

Acute myocardial infarction at a district hospital in KwaZulu-natal ­ management and outcomes

Acute myocardial infarction (AMI) following ischaemic heart disease (IHD) is associated with increased morbidity and mortality. The condition remains a management challenge in resource-constrained environments. This study analysed the management and outcomes of patients presenting with AMI at a district hospital in KwaZulu-Natal. Methods: A descriptive study that assessed hospital records of all patients diagnosed with AMI over a 2-year period (01 August 2016 to 31 July 2018). Data extracted recorded patient demographics, risk factors, timing of care, therapeutic interventions, follow up with cardiology and mortality of patients. Results: Of the 140 patients who were admitted with AMI, 96 hospital records were analysed. The mean (standard deviation [s.d.]) age of patients was 55.8 (±12.7) years. Smoking (73.5%) and hypertension (63.3%) were the most prevalent risk factors for patients with ST elevation myocardial infarction (STEMI) in contrast to dyslipidaemia (70.2%) and hypertension (68.1%) in patients with non-ST elevation myocardial infarction (NSTEMI). Almost 49.5% of patients arrived at hospital more than 6 h after symptom onset. Three (12.5%) patients received thrombolytic therapy within the recommended 30-min time frame. The mean triage-to-needle time was 183 min ­ range (3; 550). Median time to cardiology appointment was 93 days. The in-hospital mortality of 12 deaths considering 140 admissions was 8.6%. Conclusion: In a resource-constrained environment with multiple systemic challenges, in-hospital mortality is comparable to that in private sector conditions in South Africa. This entrenches the role of the family physician. There is need for more coordinated systems of care for AMI between district hospitals and tertiary referral centres.

Clinical characteristics and outcomes of patients with COVID-19 infection and acute ischemic stroke at Eka Kotebe general hospital in Addis Ababa, Ethiopia

BACKGROUND: Acute ischemic stroke has been reported to occur in a significantly higher number of COVID-19 patients as compared to healthy controls with variable proposed pathophysiologic mechanisms. To our knowledge, sufficient data regarding this subject is lacking in Ethiopia and the African continent at large. In this case series, we report the clinical characteristics and management of 5 cases with COVID-19 infection and acute ischemic stroke to shed light on the diagnostic and therapeutic challenges in resource-limited setups. METHODS: This is a case series including data collected from the medical records of 5 participants with confirmed RT-PCR positive COVID-19 infection and radiologically confirmed acute ischemic stroke, admitted at Eka Kotebe General Hospital Intensive Care Unit (ICU) in Addis Ababa, Ethiopia from June 10, 2020, to November 04, 2020. RESULTS: Cryptogenic stroke was documented in 4/5 participants included in this series with the most common vascular risk factors identified for stroke being hypertension and diabetes mellitus. The median time from onset of COVID-19 symptoms to the identification of stroke was 07 days. Two fifth of the participants in this series died during their ICU admission with the immediate cause of deaths reported to be related to the severe COVID-19 infection but not stroke. CONCLUSION: Cryptogenic stroke was documented in 4/5 patients in this series despite the presence of vascular risk factors for other stroke subtypes. The overall prevalence, subtypes, and outcomes of stroke in COVID-19 patients in Ethiopia and the African continent as a whole needs additional research to elucidate the local burden of the disease and define the predominant pathophysiologic mechanisms for stroke in COVID-19 in the region

Cardiogenic Embolisation And Ischaemic Stroke: A Review Of Cases Seen At The University Of Nigeria Teaching Hospital Enugu

A review of hospital admissions for stroke between January 1980 and December 1999 at the medical wards of the University of Nigeria Teaching Hospital in Enugu; Nigeria was undertaken to ascertain the frequency; patterns and risk factors associated with ischaemic strokes attributable to cardiogenic brain embolization. The results showed that of 450 medical admissions for ischaemic stroke; 5.1 (23 cases) were cerebral infarction related to cardiogenic embolism. There was a male preponderance (5.7 males:2 females). The highest rate of cerebral embolism was seen in the age group 50-59 years. The commonest observed risk factors included hypertension in association with atrial fibrillation (AF; 21.7) and hypertensive left ventricular hypertrophy (17.4). The right cerebral hemispheres were more frequently affected (43.5). The relative risk of cerebral cardioembolism attributed to AF; cardiomyopathy; and hypertension were 13.34 (confidence interval; CI 11.5; 15.5); 9.8 (CI 6.3; 1.6); and 0.27 (CI 6.1; 2.2); respectively. There is a need for physicians to properly identify patients at risk for cardiogenic cerebral arterial embolization in whom anticoagulation may be beneficial
