Self-driving and multimedia systems have common implications: increased demand on network bandwidth and computation nodes. To cope with the current and future challenges, intra-vehicular networks (IVNs) change their layout. They are built around powerful central nodes connected to the rest of the vehicle via Ethernet. The usage of Ethernet presents a challenge, as it by design lacks support for deterministic behavior, which is crucial for real-time systems. Therefore, the IEEE Time-Sensitive Networking (TSN) task group offers standards introducing low-latency and deterministic communication into Ethernet based networks allowing coexistence of best-effort and real-time traffic. To understand the coexistence challenges, these new networked systems need to be thoroughly evaluated with IVN requirements in mind. To assess various topologies, configurations, and data traffic types in IVN setups, we introduce Environment for Generic In-vehicular Networking Experiments—EnGINE. It allows, among many others, repeatable, reproducible, and replicable TSN experiments with high precision and flexibility. EnGINE is based on commercial off-the-shelf hardware and uses the flexible Ansible framework for experiment orchestration. This allows us to configure various topologies emulating realistic behavior of IVNs or other time sensitive systems used, e.g., in industrial automation. Obtaining such realism is challenging using simulations. Based on available related work, we further address the challenges found in those networks, especially IVNs. We derive TSN domain framework requirements, provide details on design decisions for the EnGINE, and present results to show its capabilities. The results present relevant network metrics based on collected data. A key focus is on the experiment campaigns realism achieved by real IVNs’ data footage and the OS optimizations to offer real-time behavior. We believe that EnGINE provides the ideal environment for TSN experiments from different domains.

Introduction: Cardiovascular diseases constitute the deadliest pathology in the world with 31% of global mortality in 2018. This is how we felt it necessary to conduct a study on cardiovascular diseases in emergency units of Senegal, more precisely in Dakar, in order to know epidemiological profile of these patients. Methods: The study setting was the reception and emergency units of the Hopital de Pikine and Hopital Principal de Dakar. This was an observational, descriptive cross-sectional study with an analytical aim to search for factors associated with the occurrence of cardiovascular disease. The study ran from January 25th to February 5th, 2018 at the Hopital de Pikine and from February 25th to March 5th, 2018 at Hopital Principal de Dakar. The source population consisted of patients over 18 years of age and not in a state of pregnancy, who were been received there and had given their free and informed consent to participate in the survey. A representative sample had drawn and a consecutive recruitment of eligible patients were been carried out. The data collection tools were been based on the WHO STEPwise survey questionnaire. Data collection was been carried out in accordance with ethical rules. Results: The study involved 615 patients. The proportions of sedentary lifestyle, low daily consumption of fruits/vegetables, overweight and obesity were 72.4%, 96.4%, 22.7% and 17.3% respectively. This was 55.5% of women who had a waist circumference that corresponded to a high risk of a cardiovascular event and 10.2% for men. 38.9% of patients had blood pressure above 140/90mmhg and 32.2% said they had never controlled their blood pressure in their life. The use of a consultation in a health structure to control his blood pressure was by far the most frequent modality with 61.4%. The proportion of people with cardiovascular disease was 50.1%. Hypertensive flare-ups/hypertensive emergencies were the leading complications diagnosed with 33.33%. Factors associated with the occurrence of cardiovascular disease were sex, age, professional status and body mass index. Discussion & Conclusion: The risk factors for cardiovascular disease are highly represented in our emergency units. In addition to the available care offer, the identification of factors associated with the occurrence of cardiovascular diseases in patients who are been seen there will allow targeted preventive actions within this fragile and vulnerable population. All this to help achieve target 3.4 of the Sustainable Development Goals (SDGs) by 2030. Furthermore, according to the associated factors identified, it appears that achieving SDG 8 will greatly contribute to the prevention of cardiovascular disease. This proves the urgency and interest of an integrated multi-ministerial vision in our strategic plans for the prevention against major non-communicable diseases and cardiovascular diseases in particular.

Background: Peripheral arterial disease (PAD) is common in patients with chronic kidney disease (CKD). It is a surrogate marker of generalized atherosclerosis. In sub-Saharan Africa, PAD remains understudied in CKD. Ankle-brachial index (ABI) is a non-invasive and cost-effective tool to diagnose PAD. Objectives: Our aim was to determine the prevalence and associated risk factors for PAD in hemodialysis patients. Patients and Methods: We conducted a cross-sectional study from July 1 to December 31, 2012 in the department of Nephrology of the University Hospital Aristide le Dantec of Dakar. All consenting patients, aged above 18 years, on hemodialysis for at least 6 months were included. ABI measurements were performed using a handled pulse doppler. PAD was defined as an ABI of

Introduction: Cardiovascular disease is a global public health problem. In Africa, they are increasingly common, however, data on the control of cardiovascular risk factors in the general Senegalese population are rare. The aim of this work was to assess the level of control of cardiovascular risk factors in semi-urban areas in the municipality of Gueoul in Senegal. Patients and methods: This is a cross-sectional, descriptive and exhaustive survey carried out from 3 November to 3 December 2012 among the population aged at least 35 years and living for more than 6 months in the commune of Gueoul. It was conducted using the WHO STEPS approach to study the prevalence of cardiovascular risk factors and assess their level of control. We looked at clinical history, lifestyle, and anthropometric data. Blood pressure was measured at both arms and fasting blood samples were taken for blood glucose, cholesterol and triglycerides. Results: We examined 1.411 subjects (1052 women) averaging 48.5 ± 12.7 years of age. The main cardiovascular risk factors were dyslipidemia (61%), sedentary (56%), abdominal obesity (53.9%), high blood pressure (46.4%) and diabetes (7.2%). Dyslipidemia was known in 22 subjects, 6 of whom were on treatment with dyslipidemia control in 1 subject (16.7%). Hypertension was known in 266 subjects. Of these, 205 subjects were prescribed medical treatment, 26 of whom were well controlled (12.7%). The level of hypertension control was lower in subjects at high cardiovascular risk (p = 0.0001) and those with a family history of hypertension (p = 0.001). The male gender (p = 0.24), the short duration of progression of hypertension (p = 0.95) and the noncompliance of the diet (p = 0.176) were not significantly associated with poor control of hypertension. In diabetics, subjects on oral antidiabetic drugs had met fasting glucose targets in 65.5% of cases according to the recommendations of the American Diabetes Association and in 58.6% according to those of the International Diabetes Federation (p = 0.0001). Age, regular physical activity and insulin treatment were not significantly related to fasting blood sugar control. Conclusion: Our study found inadequate control and high prevalence of cardiovascular risk factors in the general Senegalese population. This situation could be a cause of aggravation of cardiovascular diseases in Senegal and should promote to improve their management.

The care of acute coronary syndrome with persistent ST-elevation (STEMI) is a time-trial race: ‘‘time is myocardium”. The treatment relies on myocardial reperfusion by percutaneous coronary intervention (PCI) or fibrinolysis as promptly as possible. The main objective of this work was to assess the care time delays and the delaying factors during STEMI. We conducted a prospective, descriptive and analytic study over a 6 months’ time period. Were included all the patients received for STEMI. We have studied the care time delays and the delaying factors. We have compiled 50 patients. The mean age was 58.4 years and the sex-ratio M/F 2.5. The chest pain was typical in 39 patients. The mean time elapsed between the beginning of the pain and the first medical contact was 12 h 16 min. Transport (76%) and self-medication (70%) were the significant delaying factors found (p = 0.0001). The mean time elapsed between the first medical contact and the electrocardiogram was 9 h 57 min. The main factors delaying the diagnosis were the unavailability of the electrocardiogram device and the absence of electrocardiogram prescription (p = 0.001). The mean time elapsed between the electrocardiogram and the admission in the cardiology department was 3 h 02 min. The transport was the principal factor lengthening that time delay (p = 0.0001). Among the patients admitted directly in cardiology department, the mean time delay to perform the ECG was 30 min. The mean time delay of fibrinolysis was 2 h 11 min. Streptokinase shortage was the most frequent delaying factor (p = 0.001). The mean time delay between the qualifying ECG and the PCI completion was 2 h 42 min. The unavailability of the medical team was the first factor lengthening that time delay (p = 0.0001). The care time delays were lengthened enough in our context. This testifies to the lack of a codified strategy for STEMI care. It is essential to develop pre-hospital emergency medicine and sensitize the population and healthcare professionals.

Deep vein thrombosis of the upper limb is a rare location of venous thromboembolic disease. Data on this form of thrombosis are limited. We report six cases collected in Dakar. The sex ratio was 0.5 and the average age was 27.6 years with extremes of 17 and 39. Painful limb edema was the most constant sign and involved the non-dominant limb in almost all patients. Thrombosis occurred in a field of peripartum cardiomyopathy in two patients and SS sickle cell disease in one patient taking oral contraception. There was neither cancer nor venous catheter in medical history. The diagnosis was made by venous Doppler ultrasound in all patients. Subclavian involvement was the most common. The thrombophilia assessment, done for two patients, was normal. It was about exertion thrombosis on three (3) patients. All the patients had received antivitamin K treatment relaying a low molecular weight heparin. Venous limb compression was associated with anticoagulation for all patients. The treatment duration was six (6) months. There were no reports of pulmonary embolism or death. One patient presented a post-thrombotic syndrome.

Many parts of the developing world, especially Sub-Saharan Africa, completely lack access to cardiac pacing. The authors initiated a multinational program to implement cardiac pacing in 14 countries in Sub-Saharan Africa (1996 to 2018), aiming to eventually build self-sustainable capacity in each country. This was based on an "on-site training" approach of performing procedures locally and educating local health care teams to work within resource-limited settings, with prospective evaluation of the program. In 64 missions, a total of 542 permanent pacemakers were implanted. In 11 of these countries, the first pacemaker implant in the country was through the mission. More than one-half of those initially listed as suitable died before the mission(s) arrived. The proportion of implantations that were completely handled by local teams increased from 3% in 1996 to 98% in 2018. These findings demonstrate the feasibility and effectiveness of a proctorship-based approach to the development of local cardiac pacing capabilities in Sub-Saharan African nations.

Background With development of cholesterol management guidelines by the American College of Cardiology/American Heart Association (ACC/AHA), more individuals at risk of cardiovascular disease may be eligible for statin therapy. It is not known how this affects statin eligibility in the Africa and Middle East Region. Methods Data were used from the Africa Middle East Cardiovascular Epidemiological (ACE) study. The percentage of subjects eligible for statins per the ACC/AHA 2013 cholesterol guidelines and the 2002 National Cholesterol Education Program-Adult Treatment Panel (NCEP-ATP III) recommendations were compared. Analyses were carried out according to age, gender, community (urban/rural), and country income categories based on World Bank definitions. Results According to the ACC/AHA recommendations, 1695 out of 4378 subjects (39%; 95% confidence interval [CI], 37–40%) satisfied statin eligibility criteria vs. 1043/4378 (24%; 95% CI, 23–25%) per NCEP-ATP recommendations, representing a 63% increase in statin eligibility. Consistent increases in eligibility for statin therapy were seen according to the ACC/AHA vs. NCEP-ATP guidelines across sub-groups of age, gender, community, and country income. Notable increases for statin eligibility according to ACC/AHA vs. NCEP-ATP were seen, respectively, in subjects aged ≥65 years (86% vs. 39%), in males (46% vs. 25%), in low-income countries (28% vs. 14%), and rural communities (37% vs. 19%). Conclusion An increase in statin eligibility was seen applying ACC/AHA cholesterol guidelines compared with previous NCEP-ATP recommendations in the Africa Middle East region. The economic consequences of these guideline recommendations will need further research. Trial registration The ACE trial is registered under NCT01243138.

Hemodynamic instability secondary to left atrial (LA) compression by an aortic aneurysm is a rare entity. We report the case of a 43-year old woman with no previous diagnosis of congestive heart failure who was admitted for an initial diagnosis of pulmonary embolism (PE) based on shortness of breath, hypotension and D-Dimers elevation. The electrocardiogram and blood counts were within normal limits. The chest X-ray revealed widening of the mediastinum. Transthoracic echocardiography demonstrated LA compression by a large descending thoracic aortic aneurysm. Left and right ventricle systolic functions were preserved. Chest angiography showed LA and left pulmonary artery (LPA) compression by a descending aortic aneurysm and an intramural hematoma with no evidence of PE evidence. Emergency surgery could not be done because of her financial status. She was treated medically and was discharged 1 week later with significant improvement. However she remained hypotensive.

Introduction: Le but de l’etude etait de determiner la prevalence ainsi que les principaux facteurs de risque associes au developpement des calcifications valvulaires du cœur et/ou d’au moins un gros tronc arteriel chez les hemodialyses. Patients et methodes: Etaient inclus les patients qui avaient presente a l’echodoppler cardiaque une calcification valvulaire du cœur et ou d’au moins un gros tronc arteriel. Les variables suivantes avaient ete etudiees : epidemiologiques, cliniques et paracliniques. Resultats: Sur 54 patients hemodialyses, 51 avaient ete explores parmi lesquels 39 presentaient des calcifications cardio-vasculaires. Les femmes etaient les plus touchees 66.67 % avec un sex- ratio de ½. Les calcifications valvulaires representaient 64.1% et les calcifications vasculaires 76.9%. Les atteintes univalvulaires representaient 68% suivies des atteintes bivalvulaires 24% et trivalvulaires 8%. Les calcifications des arteres femorales etaient les plus frequemment rencontrees 63.3% suivies des arteres iliaques 53.3 %. Conclusion: Les calcifications cardiovasculaires sont frequentes chez les hemodialyses. Les principaux facteurs de risque lies a la survenue des calcifications etaient : l’hypocalcemie, l’hypo et l’hypercholesterolemie a LDL, l’hyper cholesterolemie totale et le taux sanguin de PTHi augmente. La correction de ces troubles pourrait prevenir la survenue des calcifications. Introduction: The purpose of the study was to determine the prevalence and key risk factors associated with the development of valve calcifications of the heart and/or at least one large arterial trunk in hemodialysis. Patients and methods: Patients who had presented with cardiac echodoppler a valve calcification of the heart and or at least one large arterial trunk were included. The following variables had been studied: epidemiological, clinical and paraclinical. Results: Of 54 hemodialysis patients, 51 were explored, 39 of whom had cardiovascular calcifications. Women were the most affected 66.67% with a sex ratio of ½. Valvular calcifications represented 64.1% and vascular calcifications 76.9%. Univalvular involvement accounted for 68% followed by bivalvular involvement 24% and trivalvular involvement 8%. Calcifications of the femoral arteries were the most frequently encountered 63.3% followed by the iliac arteries 53.3%. Conclusion: Cardiovascular calcifications are common in hemodialysis patients. The main risk factors related to the onset of calcifications were: hypocalcemia, hypo and hyperlolesterolemia with LDL, hyper hyper cholesterolemia and increased blood PTHi levels. The correction of these disorders would be a way to prevent the occurrence of calcifications.

Sudden adult death is an instantaneous or rapid death of natural, unexpected or unexpected origin. As a public health issue, the global incidence of sudden death would be 20100 per 100,000 population. The main objective of our study was to assess the incidence of sudden death in Dakar. The specific objectives were to establish the epidemiological profile of sudden death, identify the circumstances of its occurrence and the medical and surgical causes, and identify the factors associated with sudden deaths from cardiovascular causes. It is an observational, descriptive, retrospective study covering a period of 5 years, from January 1, 2014 to December 31, 2018. Included in the study were all records of adults (18 years of age and over) who died suddenly, in a health facility or outside it and were autopsied in the morgues of Aristide le Dantec Hospital (HALD) and Idrissa Pouye General Hospital (HOGIP). We found 1133 cases of sudden adult death, or 28 % of autopsies. The annual average was 226.6 cases. Our series consisted of 918 men and 215 women, for a sex ratio of 3.27. The sudden death of the adult was predominantly cardiovascular in origin with 561 cases or 49.5 %. The MI occurred on average at 51.95 years of age with 164 males (84.5 % of MIs) and 30 females (15.5 % of MIs). With regard to pulmonary causes, pulmonary tuberculosis was the leading cause of pulmonary origin with 66 cases or 26.2 %. For digestive causes, generalized acute peritonitis (GAP) was the most frequent cause with 29 cases (38.7 %). The prevention of sudden death is essentially based on cardiovascular disease treatment and prevention. The African context has to deal with weak health promotion, a failure of pre-hospital care and the daily difficulties of hospital care.

Intensive and prolonged practice of sport can lead to cardiovascular and electrocardiographic changes. The purpose of this study was to describe the electrocardiographic changes in some young black Senegalese players practicing competitive basketball. We conducted a prospective descriptive analysis of surface electrocardiogram (ECG) findings related to young Senegalese Black players practicing competitive basketball. The study involved 40 young basketball players, 20 girls and 20 boys, whose average age was 17 ± 0.86 years (ranging from 17 to 19 years) and 15 ± 1.56 years (ranging from 13 to 18 years) respectively. Heart rate was lower among boys, 59 beats ± 9 beats (ranging from 42 to 85) than among girls 73 beats/ min ± 11 beats (ranging from 50 to 95) (p = 0.0004). The following features have been observed: repolarization abnormalities such as T-wave inversion V1-V4 in 3 cases (7.5%), right ventricular hypertrophy in 1 case (2.5%), right axis deviation (QRS axis) in 1 case (2.5%). Intensive and prolonged practice of basketball leads to electrocardiographic changes in the young black Senegalese players.

BACKGROUND In response to the call by the World Health Organisation to reduce premature deaths from non-communicable diseases by 25% by the year 2025 (25×25), the Pan-African Society of Cardiology (PASCAR), in partnership with several organisations, including the World Heart Federation, have developed an urgent 10-point action plan to improve detection, treatment and control of hypertension in Africa. Priority six of this action plan is to promote a task-shifting/task-sharing approach in the management of hypertension. AIM This capacity-building initiative aims to enhance the knowledge, skills and core competences of primary healthcare physicians in the management of hypertension and related complications. METHODS In a collaborative approach with the International Society of Hypertension, the British and Irish Hypertension Society, the Public Health Foundation of India and the Centre for Chronic Disease Control, the PASCAR hypertension taskforce held a continental faculty meeting in Kenya on 25 and 26 February 2018 to review and discuss a process of effective contextualisation and implementation of the Indian hypertension management course on the African continent. RESULTS A tailored African course in terms of evidence-based learning, up-to-date curriculum and on-the-job training was developed with a robust monitoring and evaluation strategy. The course will be offered on a modular basis with a judicious mix of case studies, group discussions and contact sessions, with great flexibility to accommodate participants' queries. CONCLUSIONS Hypertension affects millions of people in Africa and if left untreated is a major cause of heart disease, kidney disease and stroke. CCMH-Africa will train in the next 10 years, 25 000 certified general physicians and 50 000 nurses, capable of adequately managing uncomplicated hypertension, thereby freeing the few available specialists to focus on severe or complicated cases.

Despite the growing interest in athlete’s right ventricle and various work carried out, many uncertainties are remaining. The interest of this work resides in the determination of the particularity in right heart of the black athlete subject. We conducted a prospective study from August to October 2016 in the cardiology department of Aristide Le Dantec University Hospital in Dakar. The included patients were divided according to the sporting practice as enduring, resistant and non-athletes. The parameters studied were electrocardiographic (atrial or ventricular hypertrophies), echocardiographic: dimensions of the right cavities, systolic and diastolic functions of the right ventricle. We included 58 subjects: 38 athletes including 28 endurance and 10 resistance and 20 non-athletes. The average age of the endurance athletes was 21.9 ± 3, 75 years, 26.30 ± 4.64 in resistance ones and 24.10 ± 1.89 in the non-athletic group. Two cases of first-degree atrioventricular block were recorded in athletes. On the echocardiographic point, the atrium surfaces, as well as the transverse diameter, were greater in athletes, especially in the endurance group. The mean diameters of the admission chamber and those of the right ventricular flush chamber were larger in the group of endurance athletes. It was the same for the annular and sagittal basal mean diameters of the RV as well as the RV/LV ratio. The anterior wall of the right ventricle was larger in athletes compared to non-athletes. The vena cava was greater in athletes, the pulmonary arterial pressure higher in resistance ones.

Introduction: In Senegal, surveys have revealed areas of high endemicity of Schistosomiasis including the town of Richard Toll. We undertook this study to determine the echocardiocardiographic characteristics of school-agechildren in endemic bilharziasis. Methodology: We performed a descriptive cross-sectional study in Richard Toll and Dakar in school-age children. Results: A total of 250 children were included. There was male predominance, age between 4 and 16 (10 years old ± 2.77). Hematuria was reported in 69.6% of cases in endemic areas. Positive testing for Schistoma haematobium was found exclusively in Richard-Toll at 33.5%. The diastolic, systolic, basal and median left ventricle dimensions were larger in Richard Toll’s population compared to Dakar. It was the same for the right chambers dimensions. The average pulmonary systolic arterial pressure was greater in Richard-Toll: 26.38 ± 3.16 mmHg versus 21.82 ± 1.73 mmHg in Dakar (p Conclusion: The heart of the school-aged child in endemic area is characterized by larger cavitary dimensions.

Background Cardiac pacing is a growing activity in Sub-Saharan Africa. There is little data on the characteristics of this interventional treatment in our regions. The goal was to evaluate the results of cardiac pacing in a referral service in sub-Saharan Africa. Methods We carried out a twelve-year retrospective study (from January 1st, 2004 to December 31st, 2015) in the Cardiology Department of Aristide Le Dantec University Hospital. This work included all patients who received definitive cardiac pacing during the study period and followed up in the service. Results In total we included 606 patients. There was a growing trend in activity with a peak in 2015 (17%). The average age was 70.6 ± 12.03 years. Some patients (15.4%) came from the subregion. The patients were mostly of medium socio-economic level (53%); 14% were of low socio-economic level. Patients were symptomatic in 85% of cases (37.4% syncope). The indications were dominated by complete atrioventricular block (81.5%); sinus dysfunction accounted for 1.9% of them. A temporary pacemaker was used in 60% of cases for an average duration of 5.1 ± 6.3 days. Antibiotics, local anesthesia and analgesics were used in all cases. Implanted pacemakers were single chamber in 56% of cases and double chamber in 44% of cases. In 39 patients (6.4%), the pacemaker was a « re-used » one. The atrial leads were most often placed in a lateral position (94.5%). The ventricular ones were predominantly tined (95.7%) and more often located at the apical level. Complications were noted in 24 patients (3.9%), dominated by devices externalizations and infections, which together accounted for 2.7% of cases. The number of people in the cathlab was significantly higher and the duration of the temporary pacemaker was longer for patients who had a complication. There was no significant difference depending on the type of pacemaker used (new or reused). Seven (7) in hospital death cases were reported. Conclusion Cardiac pacing is a growing activity in Dakar.

Aims Cardiac arrhythmia services are a neglected field of cardiology in Africa. To provide comprehensive contemporary information on the access and use of cardiac arrhythmia services in Africa. Methods and results Data on human resources, drug availability, cardiac implantable electronic devices (CIED), and ablation procedures were sought from member countries of Pan African Society of Cardiology. Data were received from 23 out of 31 countries. In most countries, healthcare services are primarily supported by household incomes. Vitamin K antagonists (VKAs), digoxin, and amiodarone were available in all countries, while the availability of other drugs varied widely. Non-VKA oral anticoagulants (NOACs) were unequally present in the African markets, while International Normalized Ratio monitoring was challenging. Four countries (18%) did not provide pacemaker implantations while, where available, the implantation and operator rates were 2.79 and 0.772 per million population, respectively. The countries with the highest pacemaker implantation rate/million population in descending order were Tunisia, Mauritius, South Africa, Algeria, and Morocco. Implantable cardioverter-defibrillator and cardiac resynchronization therapy (CRT) were performed in 15 (65%) and 12 (52%) countries, respectively. Reconditioned CIED were used in 5 (22%) countries. Electrophysiology was performed in 8 (35%) countries, but complex ablations only in countries from the Maghreb and South Africa. Marked variation in costs of CIED that severely mismatched the gross domestic product per capita was observed in Africa. From the first report, three countries have started performing simple ablations. Conclusion The access to arrhythmia treatments varied widely in Africa where hundreds of millions of people remain at risk of dying from heart block. Increased economic and human resources as well as infrastructures are the critical targets for improving arrhythmia services in Africa.

Summary Background and aim: The Pan-African Society of Cardiology (PASCAR) has identified hypertension as the highest area of priority for action to reduce heart disease and stroke on the continent. The aim of this PASCAR roadmap on hypertension was to develop practical guidance on how to implement strategies that translate existing knowledge into effective action and improve detection, treatment and control of hypertension and cardiovascular health in sub-Saharan Africa (SSA) by the year 2025. Methods: Development of this roadmap started with the creation of a consortium of experts with leadership skills in hypertension. In 2014, experts in different fields, including physicians and non-physicians, were invited to join. Via faceto- face meetings and teleconferences, the consortium made a situation analysis, set a goal, identified roadblocks and solutions to the management of hypertension and customised the World Heart Federation roadmap to Africa. Results: Hypertension is a major crisis on the continent but very few randomised, controlled trials have been conducted on its management. Also, only 25.8% of the countries have developed or adopted guidelines for the management of hypertension. Other major roadblocks are either government and health-system related or healthcare professional or patient related. The PASCAR hypertension task force identified a 10-point action plan to be implemented by African ministries of health to achieve 25% control of hypertension in Africa by 2025. Conclusions: Hypertension affects millions of people in SSA and if left untreated, is a major cause of heart disease and stroke. Very few SSA countries have a clear hypertension policy. This PASCAR roadmap identifies practical and effective solutions that would improve detection, treatment and control of hypertension on the continent and could be implemented as is or adapted to specific national settings.

Background A significant number of cardiovascular disease (CVD)-related deaths occur in developing countries. An increasing prevalence of CVD is associated with a change in the macro-economy of these countries. In this post hoc analysis, CVD risk factor (CVDRF) prevalence is evaluated across countries based on national income in the Africa and Middle East Region (AfME). Methods Data from the Africa Middle East Cardiovascular Epidemiological (ACE) study were used; a cross-sectional study in 14 AfME countries (94 clinics) from July 2011–April 2012, which evaluated CVDRF prevalence in stable adult outpatients. World Bank definitions were used to classify countries as low-income (LI), lower-middle-income (LMI), upper-middle-income (UMI) or high-income (HI) countries. Four thousand three hundred seventy-eight subjects were recruited where 260 (6%), 1324 (30%), 1509 (35%) and 1285 (29%) were from LI, LMI, UMI, and HI countries, respectively. Results Of all the CVDRFs evaluated, almost two-thirds of the study population across the national income groups had abdominal obesity and dyslipidemia. Countries in the HI category were associated with a higher prevalence of diabetes (32%), obesity (44%) and smoking (16%). UMI and HI countries were associated with higher clustering of CVDRFs where at least one-third of subjects having four or more CVDRFs. Lower income countries had lower blood pressure control rates and lower percentages of outpatients achieving LDL-cholesterol targets. Conclusion The burden of CVDRFs in stable outpatients is high across the national income categories in the AfME region, with HI countries showing a higher prevalence of CVDRFs. The high burden in lower income countries is associated with sub-optimal control of dyslipidemia and hypertension. Lowering the CVDRF burden would need specific public health actions in line with positive changes in the macro-economy of these countries. Trial registration The ACE trial is registered under NCT01243138.

La pratique intensive et prolongée de sport peut induire des modifications cardiovasculaires et électrocardiographiques. L’objectif de ce travail était de décrire les modifications électrocardiographiques attribuables à la pratique de basket de compétition chez de jeunes noirs sénégalais. Les auteurs ont réalisé une étude prospective descriptive de l’électrocardiogramme (ECG) de surface de jeunes noirs sénégalais pratiquant le basket de compétition. Il s’agissait de 40 jeunes basketteurs, 20 filles et 20 garçons, dont la moyenne d’âge était respectivement de 17 ans ± 0,86 (extrêmes: 17 et 19 ans) et 15 ans ± 1,56 (extrêmes: 13 et 18 ans). La fréquence cardiaque était plus basse chez les garçons, 59 battements ± 9 battements (extrêmes: 42 et 85) que chez les filles 73 battements / min ± 11 battements (extrêmes: 50-95) (p = 0,0004). Les particularités suivantes ont été observées: des troubles de la repolarisation à type d’onde T négative de V1 à V4 dans 3 cas (7, 5%), une hypertrophie ventriculaire droite dans 1 cas (2,5%), une déviation axiale droite de QRS dans 1 cas (2,5%).

Pulmonary embolism and acute aortic dissection are two formidable cardio-vascular emergencies. Their association, although exceptional, is burdened with a heavy mortality in the absence of an early and adapted surgery. We report a case of Standford acute type A aortic dissection associated with fatal pulmonary embolism. This is a 66-years old man with a notion of a long trip received for prolonged chest pain since 3 days, of sudden onset, maximal intensity, tearing, transfixing, migratory, radiating towards the back and the loins, exacerbated by breathing. The examination noted 120 bpm tachycardia, 70% SaO2 desaturation, asymetric blood pressure and asymetric pulse, aortic insufficiency murmur and bilateral crackling rettles at lungs. The chest X-ray showed an enlargement of the upper mediastinum with double-contoured image. The electrocardiogram recorded a regular sinus tachycardia at 132 cycles/min, a lateral sub epicardial ischemia in lateral leads. CT scan revealed total thrombosis of the right branch of the pulmonary artery extending to part of the trunk and an intimal flap from the aortic arch to the abdominal aorta. The evolution was brutally lethal two days after hospitalization. The dissection of the aorta and the pulmonary embolism are medical emergencies whose association poses more difficulties as well on the diagnosis plan but especially therapeutic.

Introduction: Pulmonary Embolism (PE) is the most severe form of venous thromboembolic disease. This is a serious condition not only because of its mortality but also its sequelae. Methodology: The aim of this study is to evaluate the prognosis of patients who had an episode of PE, hospitalized in the cardiology department of the Aristide Le Dantec University Hospital in Dakar. We performed a cohort study that included all patients admitted for pulmonary embolism during the period of May 1, 2011 to February 29, 2016. Subjects were contacted for a re-evaluation during the period of August 1st to September 1st 2016. We evaluated the status of patients (death or alive), to look for signs of chronic pulmonary heart based on the electrocardiogram (right atrial and ventricular hypertrophies, aspect S1S2S3, right bundle branch) and especially on the echocardiogram (right cavitary and parietal dimensions, measurement of the PASP). Results: A total of 77 pulmonary embolism cases were counted during the study period; 70 files were retained. It was a predominantly female population, with an average age of 51.2. Low risk forms (PESI I-II) accounted for 85.7% of the sample, versus 14.3% of PESI III-IV-V forms. At the re-evaluation, we counted 18 deaths (25.7%); twenty-two patients were lost to follow up. No recurrence was noted since hospitalization. Two patients had bilateral, noninflammatory edema. Dyspnea was found in 3 patients. No patient had any sign of right heart failure. Doppler echocardiography showed dilatation of the right ventricle along parasternal long axis in 6 cases and along apical section in 5 cases respectively. Right ventricular wall hypertrophy was noted in 6 patients. The systolic function of the right ventricle was normal in all cases. The right atrium was dilated in 5 cases. Pulmonary hypertension and increased pulmonary vascular resistance were noted in 7 cases, respectively. The overall mortality factors were acute circular insufficiency, right ventricular systolic dysfunction, PESI score of at least 1, tachycardia, PASP value greater than 50 mmHg, right heart failure and dilatation of the right atrium. Conclusion: Wall dilatation and hypertrophy of the right ventricle as well as pulmonary hypertension are frequent sequelae. The parameters of the hemodynamic impact of pulmonary embolism constitute the main prognostic factors.

Background : The incidence of cardiovascular disease is growing worldwide and this is of major public health concern. In sub-Saharan Africa, there is a lack of epidemiological data on the prevalence and distribution of risk factors of cardiovascular disease. This study aimed at assessing the prevalence of hypertension and other cardiovascular risk factors among an urban Senegalese population. Methods : Using an adaptation of the WHO STEPwise approach to chronic disease risk-factor surveillance, we conducted a population-based, cross-sectional survey from 3 to 30 May 2010 on 1 424 participants aged over 15 years. Socio-demographic and behavioural risk factors were collected in step 1. Physical anthropometric measurements and blood pressure were documented in step 2. Blood tests (cholesterol, fasting blood glucose, and creatinine levels) were carried out in step 3. Results : The prevalence of hypertension was 46% (95% CI: 43.4-48%), with a higher prevalence in females (47.9%) than males (41.7%) (p = 0.015), and 50% of these hypertensive were previously undiagnosed. Mean age was 53.6 years (SD: 15.8). In known cases of hypertension, the average length of its evolution was 6 years 9 months (range 1 month to 60 years). Hypertension was significantly associated with age (p = 0.001), socio-professional category (p = 0.003), dyslipidaemia (p < 0.001), obesity (p < 0.001), physical inactivity (p < 0.001), diabetes (p < 0.001) and stroke (p < 0.001). Conclusion : We found a high prevalence of hypertension and other cardiovascular risk factors in this population. There is need of a specific programme for the management and prevention of cardiovascular disease in this population.

Introduction : L’adhesion aux tissus dentaires est un sujet en permanente evolution tant pour le choix des materiaux que des protocoles proposes au praticien, rendant ainsi difficile sa realisation en clinique. Il l’est d’autant plus pour les lesions cervicales non carieuses du fait de leur localisation et de la qualite du substrat.Objectif : Le but de ce travail etait d’evaluer a six mois l’efficacite clinique d’un adhesif auto-mordancant dans le traitement de 150 lesions cervicales non carieuses.Methode : Un total de 150 restaurations (76 avec mordancage et 74 sans mordancage) a ete place par un meme operateur chez 31 patients âges de 24 a 73 ans. L’adhesif etait applique selon les recommandations du fabricant suivi de l’application du composite Herculite® XRV Ultra (Kerr Hawe, USA). Les restaurations ont ete evaluees a trois et six mois en utilisant les criteres USPHS modifies. Les donnees ont ete statistiquement analysees en utilisant le logiciel SPSS 10.0.Resultats : Huit restaurations ont ete perdues a six mois pour celles realisees avec mordancage et onze pour celles effectuees sans mordancage. Neuf restaurations ont presente une perte clinique de l’integrite marginale. Une legere coloration marginale a ete observee sur quatre restaurations (deux avec et deux sans mordancage). Il n’y pas de difference statistiquement significative. Conclusion : Selon le protocole clinique utilise dans cette etude, les restaurations des lesions cervicales non carieuses realisees avec ou sans mordancage ont un comportement clinique acceptable a six mois.

SummaryBackgroundAlthough previous studies showed that pregnancy with heart disease is associated with significant complications, few focused on patients with valvular heart disease in sub-Saharan Africa.MethodsWe report maternal and foetal outcomes in 50 pregnant women with heart disease admitted to the Department of Cardiology of the University of Dakar, during an 8-year period.ResultsRheumatic heart disease was observed in 46 women, seven of whom had previously been operated on. Among the remaining 39, 32 had mitral stenosis (isolated or associated with other valvular lesions). At admission, 36 women presented with pulmonary oedema, two with pulmonary embolism and 18 with arrhythmia. There were 17 maternal deaths (34%). Maternal death was associated with: mitral stenosis (P=0.03); severe tricuspid regurgitation (P=0.001); New York Heart Association functional class III or IV (P=0.001); symptoms of heart failure (P

Il s’agit d’une etude transversale et descriptive portant sur une periode de 9 mois (janvier a septembre 2005). Elle a eu pour cadre le service d’Odontologie d’un centre hospitalier public de la region de Dakar (Senegal). Elle a concerne 32 patients referes au service d’Odontologie par le Service de Cardiologie. Ils presentaient une pathologie cardio-vasculaire ayant necessite la prescription d’un anti-vitamine K et ils devaient subir un acte de chirurgie buccale. L’objectif du travail etait de determiner la valeur de l’INR (International Normalized Ratio) permettant de realiser un acte de chirurgie buccale sans risque hemorragique. Nous avons exploite les parametres suivants : identification du malade, etat bucco-dentaire, type de soins bucco-dentaires, type de cardiopathies, posologie des AVK, valeur de l’INR, moyens d’hemostase. 81,25 % (26 sur 32) des patients etaient des femmes, soit un sexe ratio M/F de 0,23. La moyenne d’âge etait de 53 ans, avec des extremes de 21 ans et 84 ans. 56,25 % des patients ont subi une seule extraction, 25 % des extractions multiples et 18,75 % ont beneficie d’un detartrage-curetage. La valeur moyenne de l’INR est de 2,38 avec une variance de 0,07 et un ecart type de 0,27. Grâce aux moyens d’hemostase instaures, aucune complication hemorragique postoperatoire n’est survenue. Il semble bien que le risque d’accident thromboembolique a l’arret du traitement est beaucoup plus prejudiciable que le risque hemorragique pour le patient.

To study the prevalence of rheumatic heart disease (RHD) in schools (locally referred to as 'daaras') located in the city of Dakar and its suburbs using both clinical examination and echocardiography.This is a cross-sectional study conducted from 9 August to 24 December 2011 involving 2019 pupils, aged between 5 and 18 years selected from the 16 'daaras' of the Academic Inspectorate (Inspection d'Académie) of the city of Dakar and its suburbs. Anamnestic, clinical and echocardiographic data were collected and entered into a questionnaire designed for the study. The World Heart Federation criteria for echocardiographic diagnosis were used to diagnose RHD. p0.05 was considered statistically significant in bivariate analysis.About 60.1% of the pupils were men and the mean age was 9.7±3.3 years. 10 cases of definite RHD were detected, prevalence being 4.96 per 1000 (95% CI 2.4 to 9.1). This prevalence was five times higher with echocardiographic screening compared with clinical screening. 23 cases (11.4 per 1000) of borderline forms were detected. The populations at risk of definite RHD identified in our study were children over 14 years (p0.001), those with recurrent sore throat (p=0.003) and those residing in the suburbs of the city of Dakar (p0.001).Our study shows a relatively high prevalence of RHD. Reducing its prevalence should focus on the implementation of appropriate policies, targeting at-risk populations and focusing on raising awareness and early detection.

There are few African data available on rheumatic heart disease (RHD).To provide data on the clinical characteristics and treatment of patients with RHD hospitalized in sub-Saharan Africa.The VALVAFRIC study is a multicentre hospital-based retrospective registry of patients with RHD hospitalized in African cardiology departments from 2004 to 2008.Among 3441 patients with at least one mild RHD lesion seen on echocardiography in 5 years in 12 cardiology departments from seven countries, 1385 had severe lesions (502 men; 803 women; mean age 29.3±15.6 years). The ratio of severe to any RHD valvular lesion was higher in countries with the lowest gross domestic product (GDP). Mitral valve regurgitation was seen in 52.8% of cases, aortic regurgitation in 32.1%, mitral stenosis in 13.4% and aortic stenosis in 1.8%. Combined valvular lesions were observed in 13% of cases. Heart failure was present in 40% of patients. Major left ventricular dilatation was observed in 13.6% of patients, ectasic left atrial dilatation in 13.8%, dilatation of the right cardiac chambers in 19.8% and pulmonary hypertension in 28.7%. Patients with no formal schooling (41.5%) were older and had a higher New York Heart Association (NYHA) class and a lower ejection fraction (EF). Among patients aged20 years (mean age 14.5±3.8 years), those who were schooled had a lower NYHA class (2.86±0.92 vs 3.42±0.93; P0.01) and a higher EF (60.3±11.7 vs. 54.8±12.8; P0.05) than those who were not. RHD-related delays or school failures were affected by NYHA class, EF and the number of children in the household. Although 1200 of 1334 patients required valve repair or replacement, only 27 had surgery. In-hospital outcomes included death (16%), heart failure (62%), arrhythmias (22%), endocarditis (4%) and thromboembolic events (4%). Subsequently, 176 patients were readmitted (13.6%).Patients with RHD hospitalized in sub-Saharan Africa are young, socially disadvantaged, with a high mortality rate and extremely low access to surgery. Poverty, as quantified by GDP and educational level, affects RHD-related severity, NYHA class and left ventricular dysfunction.

Summary Background Whereas the coronary artery disease death rate has declined in high-income countries, the incidence of acute coronary syndromes (ACS) is increasing in sub-Saharan Africa, where their management remains a challenge. Aim To propose a consensus statement to optimize management of ACS in sub-Saharan Africa on the basis of realistic considerations. Methods The AFRICARDIO-2 conference (Yamoussoukro, May 2015) reviewed the ongoing features of ACS in 10 sub-Saharan countries (Benin, Burkina-Faso, Congo-Brazzaville, Guinea, Ivory Coast, Mali, Mauritania, Niger, Senegal, Togo), and analysed whether improvements in strategies and policies may be expected using readily available healthcare facilities. Results The outcome of patients with ACS is affected by clearly identified factors, including: delay to reaching first medical contact, achieving effective hospital transportation, increased time from symptom onset to reperfusion therapy, limited primary emergency facilities (especially in rural areas) and emergency medical service (EMS) prehospital management, and hence limited numbers of patients eligible for myocardial reperfusion (thrombolytic therapy and/or percutaneous coronary intervention [PCI]). With only five catheterization laboratories in the 10 participating countries, PCI rates are very low. However, in recent years, catheterization laboratories have been built in referral cardiology departments in large African towns (Abidjan and Dakar). Improvements in patient care and outcomes should target limited but selected objectives: increasing awareness and recognition of ACS symptoms; education of rural-based healthcare professionals; and developing and managing a network between first-line healthcare facilities in rural areas or small cities, emergency rooms in larger towns, the EMS, hospital-based cardiology departments and catheterization laboratories. Conclusion Faced with the increasing prevalence of ACS in sub-Saharan Africa, healthcare policies should be developed to overcome the multiple shortcomings blunting optimal management. European and/or North American management guidelines should be adapted to African specificities. Our consensus statement aims to optimize patient management on the basis of realistic considerations, given the healthcare facilities, organizations and few cardiology teams that are available.
