RESUMEN

Cancer is associated with a hypercoagulable state and is a well-known independent risk factor for venous thromboembolism, whereas the association between cancer and arterial thromboembolism is less well established. Arterial thromboembolism, primarily defined as myocardial infarction or stroke is significantly more frequent in patients with cancer, independently of vascular risk factors and associated with a three-fold increase in the risk of mortality. Patients with brain cancer, lung cancer, colorectal cancer and pancreatic cancer have the highest relative risk of developing arterial thromboembolism. Antithrombotic treatments should be used with caution due to the increased risk of haemorrhage, as specified in current practice guidelines.

RESUMEN

Cerebrospinal patients are victims of acquired brain lesions of multiple etiologies: head trauma, stroke, brain tumors, arteriovenous malformations, progressive degenerative diseases. Their care requires a combination of neurological, neuropsychological, psychiatric and psychopathological knowledge. Psychological follow-up of patients with cerebral palsy is one of the dimensions of their care.

RESUMEN

Between 2016 and 2018, twenty maternal deaths were associated with a stroke. The 20 deaths whose main cause was stroke represent 7.4% of all maternal deaths, i.e. a maternal mortality ratio (MMR) of 0.9 per 100,000 live births (95%CI 0.6-1.3). Among the 20 stroke deaths, it was hemorrhagic in 17 cases (85%), ischemic in 2 cases, and due to thrombophlebitis in 1 case. Stroke occurred during pregnancy in 8 women (40%) - one case before 12 weeks, 3 cases between 28 and 32 weeks, and 4 cases between 34 and 40 weeks; in 3 cases the stroke occurred intrapartum, and for the other 9 cases (45%) the stroke occurred postpartum between Day 1 and Day 15. Care was assessed as non-optimal in 10/19 (56%) of cases but mortality as possibly avoidable in 24% of cases (4/17 cases with conclusion established by the CNEMM) and not established in two cases. The potentially improvable elements identified were a delay in carrying out initial brain imaging in three cases (one case antepartum, two cases postpartum) and insufficient hemodynamic monitoring in intensive care in one case.

RESUMEN

PURPOSE: To identify all reported cases of retinal artery occlusion (RAO) associated with patent foramen ovale (PFO) in the literature and present a similar case of CRAO from our clinic. METHODS: PubMed database was searched for studies reporting RAO in individuals with PFO. Relevant data were tabulated and reviewed. We estimated each case's Risk of Paradoxical Embolism (RoPE) score. RESULTS: 23 cases of CRAO (n=10; including ours), BRAO (n=10), and CILRAO (n=3) were reviewed. Most cases were under 50 years of age (78.3%). The reported predisposing factors were: hypertension (26.1%), migraine (17.3%), smoking (13.0%), recent immobilization (13.0%), strenuous exertion (8.7%), pregnancy (8.7%), and diabetes (4.3%). A high RoPE score (≥7; suggestive of paradoxical embolism via PFO) was estimated for 71.4% of patients. In most cases, the neurological and cardiovascular examinations, laboratory studies, and imaging were unremarkable, except for the PFO±atrial septal aneurysm (present in 21.7%). In only 28.6% of cases, transthoracic echocardiography (TTE) (± saline contrast) could visualize the PFO; transesophageal echocardiography (TEE) was necessary to detect the PFO in 71.4%. Approximately one-half of the patients underwent percutaneous closure of the PFO; no complications or subsequent acute ischemic events ensued. The visual prognosis was poorer for CRAO than for BRAO or CILRAO. CONCLUSION: Timely diagnosis, acute management, and ensuring urgent initiation of stroke workup in cases with RAO or transient monocular vision loss are crucial. Clues to a possible paradoxical embolism as the cause include the absence of known cardiovascular risk factors, young age, migraine, recent immobility, vigorous exercise, and pregnancy.

RESUMEN

An experimental art-mediated psychotherapy workshop is offered to patients who, after a stroke, find their physical and mental capacities diminished. The traumatic experience of this brutal event and the resulting handicaps are a source of psycho-affective disorders that can hinder favorable motor recovery. The workshop's ethnoscenological approach provides an integrative reading of the psychological mechanisms at play, enabling us to work psychologically with the modified body through experiential performative practice and stage exercises that encourage the embodiment of the imaginary.

RESUMEN

PURPOSE: To assess the level of the control of the cardiovascular risk factors in patients with a history of stroke in the Democratic Republic of the Congo. METHODS: The level of the control of arterial hypertension, diabetes mellitus, and dyslipidemias was analyzed in two hundred and seventy-four (274) patients followed for stroke. RESULTS: Among 188 patients with a prior diagnosis of arterial hypertension, only 100 (53.2%) were treated, 27 (27.0%) had their blood pressure well controlled [12.3% in acute stroke vs. 46.5% in sequelae phase; p = 0.0002].  Among 42 (71.2%) diabetics treated, 23 (63.9%) had glycaemia levels > 200 mg/dl, 60.0% in acute phase and 83.3% in sequelae phase (p = 0.28). Finally, 87.0% of the patients had a non-HDL-C > 85 mg/dl. CONCLUSIONS: This study shows a poor control of modifiable cardiovascular risk factors in patients with very high cardiovascular risk due to stroke. There is a need for an effective program to combat non-communicable diseases in our environment.

RESUMEN

BACKGROUND: Atrial fibrillation is associated with increased risk of morbidity and mortality. There's limited data on the outcomes of atrial fibrillation patients in Africa. We aimed at evaluating the clinical outcomes and their associated factors in patients with atrial fibrillation on antithrombotic therapy in Douala. METHODS: The Douala atrial fibrillation registry is a prospective, observational cohort study of patients with atrial fibrillation followed by cardiovascular specialists in 3 specialized care centres. From January to April 2018, all patients with electrocardiographic diagnosis of atrial fibrillation, aged 21 years or older, were included in the registry provided their consent. The composite endpoint of heart failure, stroke, major bleeding, hospitalisation and mortality as well as their individual occurrence were assessed at 12 months. RESULTS: Of 113 participants that were included, 6(5.3%) were lost to follow-up. The mean age was 70 ± 12 years, with a female predominance (68%). After a mean follow-up time of 12.2 ± 0.7 months, 51 patients (47.7%) had at least one outcome. Hospitalisation, all-cause mortality, heart failure, stroke and major bleeding rates were 33.3%, 16.8%, 15.2%, 4.8% and 2.9% respectively. There was no significant difference in the composite outcome and mortality according to the antithrombotic treatment. Previous heart failure [aHR = 3.07, 95% CI (1.48-6.36) p = 0.003], new onset atrial fibrillation [aHR= 4.00, 95% CI (0.96-8.19) p < 0.001] and paroxystic atrial fibrillation [aHR= 3.74, 95% CI (1.33-10.53) p = 0.013] were significant predictors of outcome. CONCLUSION: Half of patients with atrial fibrillation in this registry developed an outcome after one year of follow-up, with heart failure, new onset and paroxystic atrial fibrillation being the main predicting factors. Diagnosing and managing atrial fibrillation in patients with heart disease should therefore be considered as a key priority.

RESUMEN

BACKGROUND: The polypill strategy could become widely accepted in cardiovascular prevention due to reduced costs and its simplicity, which promote compliance. Aspirin is often included as a component of the polypill for primary prevention, but three powerful recent trials failed to show any favorable net benefit even in high-risk subgroups. Our objective is to estimate the net benefit associated with aspirin in primary cardiovascular prevention. METHODS: We simulated the impact of different polypill compositions combining pravastatin, ramipril, hydrochlorothiazide, with or without aspirin, on a realistic French virtual population between 35 and 65 years old. We assessed how this impact on myocardial infarction and stroke varied according to gender, diabetes, and arterial hypertension. We identified the subgroup of individuals whose specific benefit from aspirin was greater than twice the risk of serious bleeding it induced. RESULTS: The absolute benefit associated with aspirin was reduced by co-prescriptions. No subgroup of women benefited from aspirin, and the subgroup of women with a clear net benefit represented 128 women out of 529,421. Men at high risk of cardiovascular death, or with diabetes and hypertension, had a benefit from aspirin exceeding the risk of bleeding induced, but this risk represented more than half of the benefit. No subgroup analyzed did show a benefit greater than twice the risk of bleeding. The proportion of men whose expected benefit from aspirin was greater than twice the risk of bleeding represented 3% of all men. An optimal polypill strategy in primary prevention between the ages of 35 and 65, combining three drugs but not aspirin, can hope to save two out of three strokes and more than one out of two myocardial infarctions. It would prevent a major cardiovascular accident every 16 to 193 individuals treated according to the subgroups considered. CONCLUSION: Until proven otherwise, aspirin has only a limited place in individuals between 35 and 65 years without a cardiovascular history. We showed how simulating therapeutic strategies on a realistic virtual population could be used for best applying available evidence.

Background. Stroke is a frequent pathology. The aim of the study was to describe the clinical, and prognostic aspects of stroke in the intensive care unit (ICU). Patients and Methods. This was a longitudinal descriptive and analytical study, which took place from January to April 2019. We recruited from the intensive care units of three university hospitals in Yaoundé. Any patient hospitalised in the ICU for stroke management who had undergone a brain scan was included. Consent was obtained from the patient or a relative. The variables were socio-demographic data, clinical data, therapeutic data and outcome. Data were analysed using Epi info 3.5.4 and Microsoft Office Excel 2013. Proportions were compared using the Chi-square test or Fisher's exact test. Medians were compared by the Mann-Whitney test. Survival was represented by a Kaplan Meier curve. Results. A total of 34 patients were included. The mean age was 59.9±9.7 years. The sex ratio was 0.7. The mean time to admission was 4.5 days ±4.84. Hypertension was the dominant risk factor (42.5%). Altered consciousness was common (73.5%). Hemiplegia was the main focal neurological sign. Hemorrhagic stroke was found in 58.8% of the patients. All patients received general measures. Two patients were intubated (5.88%). Eighteen deaths were recorded (52.9%). The average length of stay was 21.8±19.4 days. Prognostic factors were Glasgow score <8 (P=0.01), NIHSS score≥15 (P=0.001), hyperthermia (P=0.04), presence of swallowing disorder at admission (P=0.01) and mass effect on brain scan (P=0.01). Conclusion. Stroke remains a frequent condition in our country. Mortality is high. It is related to the clinical severity and the occurrence of complications.

RESUMEN

BACKGROUND: Coronary artery embolism (CAE) is a rare, non-atherosclerotic cause of acute myocardial infarction (MI). Atrial fibrillation (AF) is the most frequent cause of CAE, and can be associated with multiple embolisms, particularly in the brain. AIMS: To characterize CAE-related myocardial injury, assess the proportion of cardiocerebral infarction and characterize brain injuries associated with dual embolism. METHODS: In this prospective study, patients with CAE-associated MI underwent (1) cardiac magnetic resonance imaging (MRI) to assess the extent of infarct transmurality and myocardial necrosis size and (2) brain MRI to assess the proportion of simultaneous cardiocerebral infarction. We screened 1401 consecutive patients with de novo acute MI from January 2019 to June 2021. CAE was diagnosed based on clinical, angiographic and diagnostic imaging criteria. RESULTS: Overall, 29/1401 patients presented with CAE (2.1%), of whom 21 underwent cardiac and cerebral MRI. Of these, nine (43%) had an ischaemic stroke, and AF was the leading cause of CAE in 14 patients (67%). Multiple CAE were common at coronary angiography (33%). Four patients (19%) had left atrial appendage thrombus - 4/9 patients (44%) with a stroke but 0/12 patients without a stroke. On cardiac MRI, the median (interquartile range) number of segments with acute infarction was 3 (0-11) in patients with stroke and 3 (1-6) in those without. Most acute ischaemic strokes (78%) were localized in the superficial sylvian territory and only 2/21 patients (10%) had stroke sequelae. CONCLUSION: MI-related to CAE was associated with infarctions of average size but multiple locations. Systematic brain MRI revealed that 33% of cases were associated with a stroke, which was generally asymptomatic. Further studies are required to better characterize the pathophysiology, clinical course and prognostic value of CAE. Moreover, optimal management strategies remain to be determined.

RESUMEN

BACKGROUND: Atrial fibrillation (AF) carries a thrombotic risk related to blood stasis in the left atrium. In patients with rheumatic valve disease and AF, the presence of severe mitral regurgitation (MR) has been shown to reduce the risk of atrial thrombosis and stroke. However, in patients without rheumatic disease, the results are controversial. AIM: To analyse the association between MR and the incidence of stroke in patients with non-rheumatic AF. METHODS: We analysed data from the retrospective CardioCHUVI-AF registry, which includes 15,720 patients with AF (without mechanical prostheses or rheumatic valvular disease) in the Vigo area of Spain, during 2014-2018. We grouped the patients according to MR grades: 0-2 (n=15,194) and 3-4 (n=526). We performed univariate and multivariable competitive risk analyses to analyse the association between MR and stroke, with death as the competitive event. RESULTS: During a median (interquartile range [IQR]) follow-up of 4.9 (2.8-4.9) years, 859 patients (5.5%) suffered a stroke. The stroke incidence was 1.3 per 100 person-years (95% confidence interval [95% CI]: 1.2-1.4), with no difference between the MR groups. In univariate analysis, no relationship was observed between MR grade and stroke (subdistribution hazard ratio [sHR]: 1.12, 95% CI: 0.79-1.60; P=0.53); likewise after multivariable analysis (sHR: 0.98, 95% CI: 0.68-1.41; P=0.90). This same relationship was evaluated in subgroups of interest (patients with and without: oral anticoagulation, CHA2DS2-VASc≥2, prior heart failure, aortic valve disease, left ventricular ejection fraction≤40%, and moderate-severe left atrial dilation), with results consistent with the overall population. CONCLUSION: In our large registry of patients with non-rheumatic AF, we did not find a protective effect of grade 3-4 MR on the risk of stroke.

RESUMEN

When hand weakness is linked to a brain lesion, there is risk of misdiagnosis. A case of hand weakness related to stroke is presented. The electromyography report indicated a segmental lesion of the median nerve at the wrist. Thus, the patient was initially diagnosed with carpal tunnel syndrome, and was referred to the orthopedic department for release surgery. Because the symptom was immediate and did not include hand numbness, the orthopedic surgeon ruled out the previous diagnosis and ordered a head CT scan, which revealed stroke. Aspirin and other medications were given. Percutaneous carotid balloon angioplasty with stent implantation and percutaneous vertebral artery balloon angioplasty were performed. The weakness of the left hand was greatly improved. So far, only a few cases suggest that hand weakness may be linked to stroke. Therefore, physicians should pay attention to physical examination.

RESUMEN

Machine learning may improve use of observational data to understand the nutritional epidemiology of cardiovascular disease (CVD) through better modelling of non-linearity, non-additivity, and dietary complexity. Our objective was to develop machine learning prediction models for exploring how nutrients are related to CVD risk and to evaluate their predictive performance. We established a population-based cohort from the Canadian Community Health Survey and measured CVD incidence and mortality from 2004 to 2018 using administrative databases of national hospital discharges and deaths. Predictors included 61 nutrition variables and fourteen socioeconomic, demographic, psychological, and behavioural variables. Conditional inference forest models were interpreted and evaluated by permutation feature importance, accumulated local effects, and predictive discrimination and calibration. A total of 12 130 individuals were included in the study. Use of supplements, caffeine, and alcohol were the most important nutrition variables for prediction of CVD. Supplement use was associated with decreased risk, caffeine was associated with increasing risk, and alcohol had a u-shaped association with risk. The model had an out-of-sample c-statistic of 0.821 (95% confidence interval = 0.801-0.842). Exploratory findings included both known and novel associations and predictive performance was competitive, suggesting that further application of machine learning to nutritional epidemiology may help elucidate risks and improve predictive models. Novelty: Machine learning prediction models were developed for CVD using dietary data. Models were interpreted with interpretable machine learning techniques, revealing diverse associations between diet and CVD. Models achieved comparable or superior predictive performance to existing CVD risk prediction models.

RESUMEN

Intracerebral hemorrhage accounts for approximately 15% of the 115,000 strokes occurring each year in France. Although therapeutic strategies are more limited than for ischemic stroke, major points in the management of intracerebral hemorrhage can reduce short term morbidity and mortality by limiting the expansion of the hematoma and the occurrence of early complications, and long term patients' outcome by reducing the risk of recurrence. This article aims to update the key elements that contribute to improve of the prognosis of intracerebral hemorrhage patients.

RESUMEN

Cryptogenic stroke is an old definition that designates an ischemic stroke with no identifiable cause. The term of the embolic stroke of undetermined source was then introduced to identify non-lacunar strokes in whom thromboembolism was the likely mechanism. This subgroup of cryptogenic strokes remains heterogeneous with many potential and possibly associated embolic causes. Covert atrial fibrillation is probably less often involved than initially expected, in contrast to intracranial and extracranial atherosclerosis. The cardiologist should be involved in the search of underlying causes of ischemic stroke by helping the neurologist to identify the most likely diagnosis. Further research is necessary to select populations that may benefit from more effective and individualized treatment.

RESUMEN

BACKGROUND: Smoking is the main modifiable risk factor for stroke and myocardial infarction, particularly in women; its prevalence in France is evolving, and new patterns of nicotine consumption have emerged. AIMS: To present contemporary data on smoking prevalence and the use of electronic cigarettes, and to describe current knowledge of the cardiovascular risk specificities and the effectiveness of withdrawal methods in women. METHOD: We identified studies by searching the MEDLINE bibliographic database between 1995 and 2020, and the Weekly Epidemiological Bulletin (Bulletin Épidémiologique Hebdomadaire) published by the French health authorities. RESULT: In recent years, smoking prevalence among French women has decreased overall, except in the oldest age group (aged>55 years). At the same time, the incidence of hospitalization for cardiovascular events has increased worryingly among women smokers aged<65 years. Active smoking in women is associated with an increased risk of premature myocardial infarction, and a risk of stroke that increases with the number of cigarettes consumed per day; it is also responsible for increased cardiovascular events in women taking oestrogen-progestin contraception. Quitting smoking reverses these effects in the long term, and women are just as likely to quit smoking as men. CONCLUSIONS: Stopping smoking must be a priority objective for women smokers, for primary and secondary prevention, and they should systematically be offered a validated method of cessation or even electronic cigarettes.
