RESUMO
OBJECTIVE: the study's objective was to determine impact of COVID-19 on the prognosis of pulmonary embolism. PATIENTS AND METHODS: An analytical multicenter cross-sectional study with retrospective data collection was carried out in three university hospitals and a private clinic in Ouagadougou from March, 2020 to July 2021. It included consecutive patients hospitalized for PE confirmed on chest CT angiography or by the association an acute cor pulmonale on echocardiography-Doppler with deep vein thrombosis on venous ultrasound-Doppler of the lower limbs and having carried out a COVID-19 test (RT-PCR or rapid diagnostic test). Control cases consisted of all COVID-19 negative PE cases. Data comparison was carried out using the Epi info 7 software. A univariate then multivariate analysis allowed the comparison of the prognosis of the two subpopulations. The significance level retained was p < 0.05. RESULTS: 96 patients with COVID-19+ and 70 COVID-19- PE were included. The prevalence of PE in patients hospitalized for COVID-19 was 7.05%. The average patient age was 61.5±17 years for COVID-19+ patients and 49.6±15.9 years for COVID-19- patients. Pulmonary condensation syndrome (p=0.007), desaturation (p=0.0003) and respiratory distress syndrome (p=0.006) were more common in COVID-19+ patients. The hospital death rate was 27.1% in COVID-19+ patients and 10% in COVID-19- patients (p=0.0024). Age > 65 years and COVID-19 pneumonia were the independent factors of death. CONCLUSION: COVID-19 is associated with clinical severity and excess mortality in patients with pulmonary embolism.

BACKGROUND: Data on hypertensive crises (HC) are limited in sub-Saharan Africa (SSA). We aimed to characterize the pattern and short-term mortality of hypertensive emergencies (HE) and urgencies (HU). METHODS: This was a prospective cohort study. Consecutive patients with acute and severely elevated blood pressure (systolic>180mmHg and/or diastolic >120mmHg) with or without acute target-organs damage attending the emergency department (ED) of the Teaching Hospital of Yalgado Ouedraogo, Ouagadougou, Burkina Faso were included with a one-month follow-up. RESULTS: One hundred and sixty-six of 1254 patients presenting to the ED (January to march 2016) had HC (13.2%) and 113 of them (68.1%) had HE. The mean age was 50.9±15.9 years and males were 63.3% (n=105). Younger age (<45 years) accounted for 55% of the cases. History of known HTN was reported in 101 patients (60.8%). Among patients with HE, 62.8% had brain-related events, 30.1% had cardiac involvement and 31% had acute renal impairment. The overall survival rate was 89% within the first 72hours and 81% at fourteen days follow-up. At one-month follow-up, 36 patients died with a survival rate of 77.8%. Factors independently associated with death were history of known hypertension, acute brain-related damage and renal dysfunction and not being transferred to a specialized department. CONCLUSION: HC are not rare in SSA and are associated with higher morbidity and mortality in HE. Further studies are needed to determine factors that promote HC in African patients in order to better address the prevention and management strategies of such hypertensive entity.

AIM: The aim of this study was to assess the quality of medical management of heart failure at the National Hospital Blaise Compaoré according to the international guidelines. PATIENTS AND METHODS: A retrospective study was performed including consecutive patients admitted for heart failure documented sonographically from October 2012 to March 2015 in the Medicine and Medical Specialties Department of National Hospital Blaise Compaore with a minimum follow-up of six weeks. Data analysis was made by the SPSS 20.0 software. RESULTS: Eighty-four patients, mean age of 57.61±18.24 years, were included. It was an acute heart failure in 84.5% of patients with systolic left ventricular function impaired (77.4%). The rate of prescription of different drugs in heart failure any type was 88.1% for loop diuretics; 77.1% for angiotensin-converting enzyme inhibitors/angiotensin receptor blockers and 65.5% for betablockers. In patients with systolic dysfunction, 84.62% of patients were received the combination of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers and 75.38% for betablockers. Exercise rehabilitation was undergoing in 10.7% of patients. The death rate was 16.7% and hospital readmission rate of 16.7%. CONCLUSION: The prescription rate of major heart failure drugs is satisfactory. Cardiac rehabilitation should be developed.

Objectif : Cette étude avait pour objectif d'étudier les facteurs associés à l'équilibre du traitement antivitamine K(AVK) chez les patients suivis au service de cardiologie du CHU-YO.Méthodologie : Il s'agit d'une étude rétrospective à visée analytique qui a recensé pendant une période de 3 mois les patients sous traitement AVK dans le service de cardiologie du CHU-YO. N'ont pas été inclus les patients dont les résultats des contrôles INR des 3 derniers mois ne figuraient pas dans le carnet de suivi. Le logiciel Epi info version 3.5 a servi à l'analyse statistique et le test de Khi2 à la comparaison au seuil de 0,05.Résultats : Nous avons colligé 193 patients. L'âge moyen était de 53 ans avec des extrêmes entre 14 et 95 ans. L'INR était stable dans 40% des cas et un accident hémorragique sous AVK a été observé dans 12%. Il y avait une prédominance non-significative de la proportion d'INR stable chez les patients qui avaient la possibilité de réaliser l'examen en leur lieu de résidence (40,7% vs 37,7%). La proportion d'INR stable était plus élevée chez les patients qui avaient un niveau d'instruction inférieur au secondaire (43% vs 35%) sans association statistique significative (p = 0,60). La proportion d'INR stable était plus élevée chez les patients sous traitement depuis au moins un an (45% vs 35%) sans association significative (p = 0,06). Les comorbidités ont été retrouvées dans 14% des cas sans association statistique avec la survenue d'un événement hémorragique. Le régime alimentaire pauvre en vitamine K a été institué chez 86% des patients, mais sans corrélation avec la stabilité de l'INR. Le bon niveau d'éducation thérapeutique était significativement associé au bon équilibre du traitement aux AVK (P = 0,0002). Conclusion : La qualité de l'éducation thérapeutique est l'élément clé du bon équilibre du traitement AVK au CHU-YO, d'où l'intérêt d'y mettre l'accent

Peripartum cardiomyopathy is a cardiac disease at high thromboembolism potential. The authors report a case of peripartum cardiomyopathy admitted for congestive heart failure. Echocardiography found a dilated cardiomyopathy with severely impaired left ventricular systolic function and biventricular thrombi. During hospitalization his condition was complicated by severe bilateral pulmonary embolism and left lower limb arterial acute thrombosis. The treatment consisted of thrombolysis with streptokinase associated with dobutamine (in addition to the conventional treatment of heart failure and bromocriptine). The outcome was favorable, marked by pulmonary and lower limb arterial unblocking.

Super hypertension is defined as systolic BP ≥ 250mmHg and/or diastolic BP ≥ 150mmHg in presence or not of complications. The aim of our study was to describe the epidemiological and evolutive patterns of super hypertension in the cardiology department of the Yalgado Ouedraogo University Hospital. It was an observation cohort over a period of 26 months (July 2011 to August 2013). We recruited 34 patients, corresponding to a prevalence of 12.9% of all hypertensive patients. The median time of follow-up was 7.1 months. The mean age was 47 years old, with a sex-ratio of 1.3. Twenty-one (62%) of the patients were known hypertensive, out of who 24% were regularly rewiewed, 57% on treatment, but none was on regular medications. Dyspnoea was the reason for consulting in 38% of the cases. We noticed a fundoscopy stage III or IV in 55.9% of the cases. All patients had left ventricular hypertrophy on ECG, and 90% on echocardiography. Complication was noticed on admission in 91% of the cases. Chronic renal failure occured in 14.7% of the cases during follow-up, and overall mortality rate was 0.5 person years. Probability of survival over one month was 70% for all patients. The mean age of deceased was 35%. Presence of renal failure, unknown hypertension, and age<45 were factors linked to death (P<0.05). Super hypertension is a pathology of the youth, with high morbi-mortality. The prevention is done through early detection and efficient management of hypertension.

INTRODUCTION: Few studies in sub-Saharan Africa were interested in resistant hypertension. The objectives of this study were to determine the frequency of resistant hypertension in hypertensive black African population, and to describe its clinical and therapeutic features. PATIENTS AND METHODS: From May 1, 2010 to May 31, 2012, we included consecutively hypertensive followed in two hospitals in the city of Ouagadougou, under antihypertensive treatment at optimum dose and observant. Patients whose blood pressure was uncontrolled despite a triple antihypertensive therapy at the optimal dose including a diuretic associated with dietary measures have received ambulatory blood pressure monitoring. Following this examination, patients whose blood pressure was ≥135/85mmHg during the day and/or ≥120/70mmHg at night were considered resistant hypertension. We investigated the cardiovascular risk factors as well as target organ damages. We combined spironolactone 50mg in treatment when absence of contra-indication appreciated the evolution of blood pressure under this treatment. The measurement of plasma renin activity was not performed. Statistical analysis was performed using SPSS Version 17 for Windows. RESULTS: We included 692 patients with 14.6% of resistant hypertension. The average age of patients was 54.8±11.1years in the general population, 56.5±11.8years in the subgroup of non-resistant hypertension and 64.2±5.4years in the subgroup of resistant hypertension. The symptoms were represented by headache (11.9%), dizziness (9.9%) and chest pain (8.9%). Modifiable cardiovascular risk factors were dominated by dyslipidemia, diabetes and obesity/overweight. These risk factors were significantly more frequent in the subgroup of resistant hypertension. The global cardiovascular risk was high in 24.9% of cases in the general population, 22.5% in the subgroup of non-resistant hypertension and 38.6% in the subgroup of resistant hypertension. The target organ damages were significantly more frequent in the same subgroup of resistant hypertension. After addition of spironolactone, 21.8% of resistant hypertensive patients were controlled. CONCLUSION: This study shows that resistant hypertension is common in black Africans. It is mostly subjects of the sixth decade, with limited economic income and living in rural areas. In the absence of contra-indication, spironolactone contributed to decrease the morbidity of this pathology.

INTRODUCTION: Infective endocarditis is a transplant of a microorganism on a most often injured endocardium. It is rare in children. This work aimed to determine the frequency of endocarditis of the child, to describe clinical presentation, data from echocardiography, microbiological profile and clinical course. PATIENTS AND METHODS: From May 1 2010 to April 30 2011, we consecutively included children received for infective endocarditis in two medical centers in the city of Ouagadougou: Saint-Camille medical center and teaching hospital Yalgado-Ouedraogo. We investigated the functional and general signs and treatment already received. The physical examination looking for an infectious syndrome, pneumonia, heart failure and entrance doors. Blood cultures, blood count, creatinine, blood chemistry, HIV status, electrocardiogram, chest radiography and cardiac Doppler ultrasound were systematic. The diagnosis of the disease was based on Duke criteria. RESULTS: Nineteen endocarditis in children were reported, that is 1.7% of admissions. The average age was 4.7 ± 2.6 years (extremes: 1 and 14). The sex ratio was 1.7 for girls. The clinical presentation was a common infectious syndrome. Impaired general condition and congestive heart failure were present on admission in six cases, respectively. The front door was dental in nine cases (47.4%), skin in four cases (21%) and ENT in three cases (15.8%). A peripheral vein was implicated in one case. In the two other cases, no front door had been found. HIV serology was positive in four cases. As for the blood cultures, they were positive in 13 cases. The germs found were Streptococcus in 10 cases and staphylococcus in three cases. Echocardiography had revealed vegetations in 18 cases. These vegetations were localized on the mitral in nine cases. Multiple locations were found in four cases. Underlying heart disease was dominated by rheumatic valve disease (68.4%), healthy heart forms were found in two cases. Treatment consisted of antibiotics, antipyretic treatment and that of heart failure as appropriate. The evolution was marked by five deaths (26.3%) in an array of septic shock. Death was more important in congenital heart disease. CONCLUSION: Infective endocarditis of the child is common in our practice. The clinical syndrome is common infectious. Streptococcus and Staphylococcus are the two germs found. The main door is dental. Hence, dental care should be promoted for better prevention of infective endocarditis in our context.

INTRODUCTION: Right-sided infective endocarditis is rare. It accounts about 5 to 10% of all infective endocarditis cases and is prevalent in patients with congenital heart disease, intravascular devices and drug addiction. Our study aimed to describe the epidemiological, clinical and echocardiographic characteristics of right-sided endocarditis and evaluate the prognosis after treatment. METHODS: From January 2010 to December 2011 we recruited all patients admitted to Yalgado Ouedraogo Teaching Hospital for infective endocarditis, and selected those who had a right-sided location. The Duke criteria were used for diagnosis. We analysed entry points and underlying heart disease. The causative organisms were tracked using blood sample cultures. Ultrasound characteristics were described, and treatment and prognosis were evaluated. Patients' follow up was conducted from recruitment to 30 June 2012. RESULTS: In the two-year period, 14 cases of right-sided infective endocarditis were recorded, including seven cases in children. They accounted for 29.1% of all infective endocarditis cases. The mean age was 25.5 ± 12.5 years (range 9-80 years). The venous route was implicated in 12 cases (85.7%). Blood cultures were positive in 11 patients. The bacteria isolated were Streptococcus pneumonia in six cases, Staphylococcus aureus in three and Hemophilus influenza in two cases. HIV status was positive in three patients. Underlying heart diseases were dominated by congenital heart disease in six cases and peripartal cardiomyopathy in four others. Vegetations were located in the right heart in only 11 cases. With antibiotic treatment, a lowering of temperature was shown within an average of 10 days of follow up. Two fatalities were reported. CONCLUSION: This study showed that right-sided endocarditis is common in our clinical practice. This infection was prevalent in patients with congenital heart disease or peripartal cardiomyopathy in our context, and the venous route seemed to be the main entry point.

INTRODUCTION: Hypertension in black is more frequent with early onset and clinically more severe. The blood pressure control and the decrease of global cardiovascular risk are two main goals of the treatment of hypertension. The objectives of this study were to determine the proportion of uncontrolled hypertension in hypertensive patients followed as outpatients and to investigate the factors associated with poor control. PATIENTS AND METHODS: This is a descriptive cross-sectional study including 456 hypertensive patients known and followed as outpatients. Blood pressure measurement was performed between 8 am and 12 noon both arms in the supine position, after a compliance averaging 8 minutes of rest. We searched for conventional cardiovascular risk factors (age superior or equal to 45 years for men and superior or equal to 55 for women, physical inactivity, overweight/obesity, smoking, diabetes and dyslipidemia) and calculated the global cardiovascular risk according to the Framingham model. Was regarded as uncontrolled high blood pressure SBP superior or equal to 140 mmHg and/or DBP superior or equal to 90 mmHg. Univariate analysis and multivariate logistic regression (using SPSS program version 17) were conducted to look for factors associated with poor blood pressure control. RESULTS: We recruited 456 hypertensive patients including 259 women (56.8%). Modifiable cardiovascular risk factors also hypertension were dominated by dyslipidemia (29.8%) and diabetes (24.6%). The global cardiovascular risk calculated using the Framingham model was low in 21.3%, moderate in 34.0%, high in 24.8% and very high in 19.9% of cases. The proportion of uncontrolled hypertension was 54.2% (n=247 including 126 women and 121 men). This poor blood pressure control was associated (multivariate analysis) at age superior or equal to 60 years, low socioeconomic status, high to very high cardiovascular risk, antihypertensive monotherapy, treatment duration superior or equal to 10 years, an associated treatment and non-compliance therapy. CONCLUSION: More than half of hypertensive patients in our study were not adequately controlled on antihypertensive therapy. Factors of poor control were age superior or equal to 60 years, low socioeconomic status, high to very high cardiovascular risk, antihypertensive monotherapy, treatment duration superior or equal to 10 years, an associated treatment and non-compliance therapy.

Although not considered as indicative of AIDS, leishmaniasis presents a number of epidemiologic and clinical features that promote opportunistic infection in HIV patients. Accurate assessment of the incidence of this type of co-infection is difficult due to underestimation in endemic areas such as Africa and Asia. In these areas the WHO estimates that 2 to 9 p. 100 of HIV patients will develop leishmaniasis/HIV co-infection which could become a major concern. The characteristics of this co-infection have been documented. It is observed in adults between 20 and 40 years of age with a strong male sex bias. The visceral form is most frequent. Manifestations are similar to those observed in immunocompetent subjects but with the possibility of asymptomatic and low-grade forms (10 p. 100) and unusual locations suggesting multiorgan spreading in absence of host immune response. In addition to the time-tested standard procedures for diagnosis of parasitic disease, new serologic tests and genomic amplification are now available. Pentavalent antimonials have long been considered as the treatment of choice but they are not always effective and can have untoward effects. Amphotericine B especially in the liposomal form is a good alternative. The particularly high incidence of recurrence suggests that follow-up may be indicated but the modalities of prophylaxis have yet to be defined.
