Causes de réhospitalisation pour insuffisance cardiaque dans le service de cardiologie du CHU de Brazzaville (République du Congo) / The causes of rehospitalization for heart failure in the department of cardiology at the university hospital of Brazzaville (Republic of the Congo)

But: Identifier les causes de réhospitalisation pour insuffisance cardiaque (IC) Patients et méthode: cette étude transversale a été menée entre avril 2014 et mars 2015 dans le service de cardiologie du centre hospitalier universitaire de Brazzaville (République du Congo). Ont été inclus, les patients ayant des antécédents d'hospitalisation pour IC. Résultats: Quatre-vingt-onze patients, 54 femmes (59,3%) ont été inclus. Le sexe-ratio était de 0,7. La fréquence de réhospitalisation pour IC était de 19%. L'âge moyen était de 62 ± 16 ans (extrêmes: 24-89 ans). Le nombre moyen de réadmissions était de 2 ± 0,8 (extrêmes: 1 à 5), les réhospitalisation fréquentes (supérieur à 3) étaient de 33 (36,2%). Les patients présentaient un statut socioéconomique faible dans 59 cas (64,8%), et une hypertension artérielle dans 40 cas (43,9%). L'examen physique a retrouvé : une insuffisance cardiaque globale 77 cas (84,6%), une insuffisance cardiaque droite exclusive 5 cas (5,5%). Les causes de l'insuffisance cardiaque étaient: la cardiopathie hypertensive 40 cas (43,9%), la cardiomyopathie dilatée 28 cas (30,8%) et les valvulopathies 9 cas (10%). Les principales causes de réhospitalisation étaient: les écarts du régime hyposodé 64 cas (70,3%), la mauvaise observance du traitement 56 cas (61,5%), la grippe 15 cas (16,5%), la fibrillation atriale 12 cas (13,2%), débit de filtration glomérulaire réduite 12 cas (13,2%). La durée moyenne d'hospitalisation était de 11 ± 6,4 jours (extrêmes: 2-29). Le décès a été enregistré dans 5 cas (5,5%). Conclusion: L'absence de respect pour un régime pauvre en sodium et une mauvaise adhésion au médicament ont été les principales causes de réhospitalisation pour IC à Brazzaville. À cet égard, il est nécessaire de promouvoir l'éducation thérapeutique et d'améliorer l'accès au traitement.

Background: to identify the causes of readmission for heart failure (HF) Methods: this cross-sectional study was conducted in April 2014 to march 2015 in the department of cardiology, University Hospital of Brazzaville (Republic of the Congo). We had included, the patients who had a history of hospitalization for HF. Results: Ninety-one patients, 54 women (59.3%) were included. Sex-ratio was 0.7. The frequency of readmission for HF was 19%. The mean age was 62±16 years (range: 24-89). The average number of readmission was 2±0.8 (range: 1-5), the history of readmission ≥ 3, were 33 (36.2%). The patients were low socio-economic status in 59 cases (64.8%). In examination, patients were in congestive HF (n=77, 84.6%), right-sided HF (n=5). The causes of HF were: hypertensive heart disease (n=40, 43.9%), dilated cardiomyopathy (n=28, 30.8%), and valvular heart disease (n=9). The main causes of readmission were: excessive salt intake (n=64, 70.3%), poor drug-adherence (n=56, 61.5%), influenza (n=15, 16.5%), atrial fibrillation (n=12, 13.2%), reduced estimate glomerular filtration rate (n=12, 13.2%). The average length of hospitalization was 11±6.4 days (range: 2-29). The death was recorded in 5 cases (5.5%). Conclusion: No respect of low sodium diet and poor drug adherence, were the most causes of readmission for HF at Brazzaville. In regard of this facts, promoting therapeutic education is needed, and increasing access to treatment

[Echocardiographic profile of Congolese hypertensive patients]. / Profil échocardiographique des patients hypertendus Congolais.

OBJECTIVES: To assess echocardiographic aspect of Congolese hypertensive patients, and to identify predictive factors of left ventricular hypertrophy (LVH). PATIENTS AND METHODS: A transversal study was lead in Brazzaville from January 2011 to December 2013 (36 months). In total, 1125 hypertensive patients under treatment underwent transthoracic echocardiography. The test was carried out either as part of an initial assessment of the hypertension disease or during the development of evocative symptom or complication. Patients' sociodemographic data and echocardiographic parameters were collected and analyzed. RESULTS: There were 621 males (55.2%) and 504 females (44.8%), mean age 54.7±12 years. The main indication of the test were the hypertension initial evaluation in 792 cases (70.4%), dyspnea in 122 cases (10.8%), investigation of ischemic stroke in 101 cases (9%), cardiac failure and chest pain in respectively 58 and 52 cases. 5.3±4.7 years known duration of hypertension status was associated with overweight/obesity in 829 cases (73.7%), physical inactivity in 669 cases (59.5%), hypertension family history in 540 cases (48%), diabetes mellitus in 122 cases (10.8%), dyslipidemia in 82 cases (7.3%), smoking in 29 cases (2.6%). Echocardiographic test was abnormal in 590 cases (52.4%) and showed hypertrophic cardiomyopathy in 510 cases (45.2%), dilated and hypertrophic cardiomyopathy in 46 cases (4.1%), dilated cardiomyopathy with systolic dysfunction in 31 cases (2.8%), coronary artery disease in 4 cases (0.4%). LVH was concentric in 470 cases (84.6%), eccentric in 70 cases (12.6%), and in 16 cases (3%), it was a concentric left ventricular remodeling. The left ventricular's systolic ejection fraction average was 70.5±9.3%, relaxation disorders in 480 cases (42.6%). Age, male gender, income, known duration of hypertension and treatment were predictive factors of LVH. CONCLUSIONS: Echocardiographic profile of the Congolese hypertensive is quite various, left ventricular hypertrophy is the most predominant abnormality. Efficient management on the hypertension will lead to reduce its morbidity and mortality.

Cost of management of nonvalvular atrial fibrillation in Brazzaville (Congo): preliminary findings.

The frequency of nonvalvular atrial fibrillation is increasing in sub-Saharan Africa, particularly as a consequence of population aging and the high prevalence of hypertension. The aim of this descriptive study was to determine the cost of management of this disease in the cardiology department at University Hospital of Brazzaville. The study included 50 patients aged 67.3 ± 12.8 years (range: 34 to 88 years). Among them, 21 (42%) were unemployed, and 49 (98%) had no health insurance. Their average monthly salary was 152.8 ± 149 € (range: 0 to 686 €). The mean total cost of care was 442.4 ± 109.8 € (range: 146.6 to 646.2 €). The average monthly salary was higher than the average cost of drugs (P <0.0001), or of additional tests (P <0.0001), or of hospital hospitality (P <0.0001). But the overall cost of care was substantially higher than the patients' mean salary (p <0.0001). This study illustrates the increasing healthcare costs related to the growing burden of cardiovascular disease in sub-Saharan Africa.

Introduction : Le but de l'étude était d'évaluer le coût de la prise en charge de l'insuffisance cardiaque et l'impact du niveau socio-économique sur l'attitude des patients.Patients et méthodes : Il s'agit d'une étude prospective et analytique réalisée dans le service de cardiologie et de médecine interne du Centre Hospitalier et Universitaire de Brazzaville, du 1er janvier au 31 décembre 2014. Ont été inclus, les patients hospitalisés pour une insuffisance cardiaque. Le coût financier était exprimé en franc de la coopération financière pour l'Afrique (FCFA). Résultats : La série comportait 279 patients répartis en 117 hommes (41,9%) et 162 femmes (58,1%), âgés en moyenne de 57,7 &plus 16,6 ans. Le revenu mensuel était inférieur à 90.000 FCFA dans 65,9% des cas, entre 90.000 et 180.000 FCFA dans 23,3% des cas et supérieur à 180.000 FCFA dans 10,8% des cas. Les patients sans aucun niveau d'instruction représentaient 27,6%. Ceux ayant les niveaux du primaire, du secondaire et du supérieur respectivement 24%, 36,6% et 11,8%. Le délai moyen de consultation était de 22 ± 23,3 jours. Il s'agissait d'un premier épisode d'insuffisance cardiaque chez 170 patients (60,9%), d'une récidive chez les 109 autres (39,1%). Pour ce dernier groupe de patients, l'observance médicamenteuse était bonne (18,3%), présentait des problèmes minimes (21,1%), n'était pas effective (60,6%). L'insuffisance cardiaque était droite chez 16 patients (5,7%), gauche chez 70 patients (25,1%) et globale chez 193 patients (69,2%). Le bilan paraclinique était réalisé chez 276 patients (98,9%) dans un délai moyen de 3,8 ± 4,2 jours. La durée moyenne d'hospitalisation était de 15,7 ± 8,5 jours, et le coût global moyen de 181.821,8 ± 79.026,3 FCFA. La prise en charge médicamenteuse ainsi que des frais d'hospitalisation relevaient du patient dans 108 cas (38,7%), d'un proche parent dans 171 cas (61,3%)

[Short-term prognosis of heart diseases managed at the pediatric intensive care unit of the Brazzaville University Hospital]. / Pronostic immédiat des cardiopathies prises en charge dans le service des soins intensifs pédiatriques du CHU de Brazzaville.

OBJECTIVE: To determine the main heart diseases of children admitted to our pediatric intensive care unit. PATIENTS AND METHODS: This cross-sectional study was conducted in 2011 (January to December) in the pediatric intensive care of the Brazzaville University Hospital. RESULTS: The study included 42 children, 27 of them girls (64.3%). Their mean age was 2.6 ± 3.4 years, and the mean age of their mothers 26.6 ± 5.1 years. The reasons for admission were dyspnea (n = 34, 81%), fever (n = 21, 50%), edema syndrome (n = 8, 19%), squatting (n = 5, 12%), impaired consciousness (n = 4), seizures (n = 3, 7.1%), shock (n = 2, 4.8%), and malaise (n = 1, 2%). Associated signs included coughing (n = 30, 71.4%), impaired general condition (n = 14, 33.3%), cyanosis (n = 9, 21.4%), and chest deformity (n = 15, 35.7%). Heart failure was found in 28 cases (66.7%), as was congenital heart disease. The main heart diseases were ventricular septal defects (n = 13), cardiomyopathy (n = 9), and the tetralogy of Fallot (n = 6). The most common factors of decompensation were anemia (n = 12, 28.6%) and bronchopneumonia (n = 11, 26.2%). The immediate mortality rate was 23.8%. CONCLUSION: The heart diseases in children admitted in critical situations usually required surgical care, not available in our country. Rapid treatment is possible by strengthening South-South cooperation with neighboring countries where cardiac surgery is available.
