[Heart rate recovery and presence of coronary lesions in case of ischemic heart disease at the Abidjan Cardiology Institute in Côte d'Ivoire]. / Fréquence cardiaque de récupération et présence de lésions coronaires au cours des cardiopathies ischémiques à l'Institut de cardiologie d'Abidjan en Côte d'Ivoire.

Introduction: Heart rate recovery (HRR) measured during stress tests, assesses the vago-sympathetic balance. It is a known prognostic and predictive parameter of cardiovascular mortality that is believed to be correlated with the presence and severity of coronary artery disease. The aim of this work was to assess the predictive value of heart rate recovery in the diagnostic and severity of coronary lesions in a major metropolis of sub-Saharan Africa where access to specialist care is unevenly distributed. Patients and method: We conducted a retrospective observational study from January 2010 to February 2020 at the Abidjan Cardiology Institute, including patients who performed a diagnostic coronary angiography after a positive exercise test. Clinical, angiographic and exercise parameters were analyzed and compared in patients with abnormal heart rate recovery (HRR) and those with normal one. Results: The main study limitation is small sampling due to the cost of the angiographic procedure which limits its realization. We recorded 41 subjects whose mean age was 53.4 ± 9.6 years with a male predominance (sex ratio of 3.6). The predominant age group was between 50 and 60 years. Males were older than females with no significant difference. The predominant cardiovascular risk factors were overweight/obesity (68.29%) and hypertension (61%). Eight patients (19.5%) presenting an abnormal HRR (≤12 bpm) had more significant coronary disease (p=0.02) and more severe ones (p=0.003). Patients with abnormal HRR tended to be older without statistical significance (p=0.081), and had lower chronotropic reserve and maximum heart rate (p=0.008 and p=0.042, respectively). The positive predictive value of HHR was 87.5% and its negative predictive value was 60.6%. Conclusion: Abnormal HRR can predict the presence of coronary artery disease and its severity. Evaluating HRR during stress tests could help in the detection, evaluation, and monitoring of ischemic heart disease in our resource-limited countries.

[Career choice of ivorian medical students at the end of curriculum: influencing factors and aspirations]. / Choix de carrière des étudiants en médecine ivoiriens en fin de cursus : facteurs d'influence et aspirations.

Introduction: The implantation of health structures in Côte d'Ivoire to improve geographical accessibility to care remains unequal between rural and urban areas. The medical student has to decide on his or her career choice in this context, while also taking into account personal preferences. The aim of our study was to evaluate the factors influencing the speciality choice of medical students at the faculty of medicine of Félix Houphouët-Boigny University in Abidjan. Methodology: Medical students enrolled in the 6th year completed an anonymous self-administered questionnaire. The questionnaire was in paper format and was divided into three parts: socio-demographic criteria; speciality choice; and factors influencing career choice. Students were asked to rate the extent to which they perceived each of the 24 items as influencing their career choice using a Likert scale ranging from 1 (no influence) to 5 (strong influence). The factors were compared according to the speciality choice (medical or surgical). Results: The 3 most chosen specialties were: cardiology (17.9%), gynaecology-obstetrics (15.7%) and paediatrics (9.6%). The desire to take the internship competition was more frequent among students who chose a surgical speciality (p = 0.02). The choice of a medical speciality was more influenced by the willingness to work part-time (p = 0.04). Students who choose a medical speciality were more guided by social commitment than those who chose a surgical speciality (p = 0.04). In contrast, the latter were more influenced by prestige among colleagues (p = 0.04) and immediate postoperative outcomes (p = 0.01). Conclusion: The efficient equipment of health structures could contribute to the development of other less chosen specialities by making them more attractive. A reorganisation of the system with the deployment of teachers in regional hospitals with a minimum of equipment is indispensable in order to allow a "decentralization" of the specialization curriculum, especially for the surgical specialties.As for the aspiration to part-time work, it can be explained by the need to reconcile family and professional life, but also by a sometimes unspoken project to develop a lucrative extra-medical activity in order to make up insufficient wages.

Transoesophageal echocardiography (TEE) at the Institute of Cardiology in Abidjan: indications, results and diagnostic accuracy.

OBJECTIVE: The aim of the study was to define the indications for and results and diagnostic accuracy of transoesophageal echocardiography (TEE) in the Abidjan Cardiology Institute. METHODS: A retrospective analysis was carried out of 103 TEE reports from February 2007 to January 2011. The analysis focused on the clinical characteristics of the patients, quality of the prescribers, and indications and diagnostic accuracy (proportion of confirmed diagnoses, which is the ratio of 'anomaly found/number of examinations made for the indication'). RESULTS: There were 47 women (45.6%) and 56 men (54. 4%) in the study, with an average age of 37.9 ± 16.4 years. Prescribers were mostly cardiologists (n = 57; 55.4%). The indications were predominantly evaluation for atrial septal defect (ASD, 34.9%), investigation for thrombus due to rhythm disturbance before cardioversion (18.4%), aetiological evaluation of ischaemic stroke (13.5%), and assessment for mitral regurgitation (lesion assessment, mechanism and/or quantification, 9.7%). In the evaluation for an ASD, TEE was contributory in 17.3% and for thrombus, it was 21%. No embolic aetiology was found in the ischaemic strokes. Three examinations weredone during cardiac surgery to assess the mechanical valves or quality of mitral plasty. There were no incidents or accidents reported during those 103 examinations. CONCLUSION: Because of the high number of congenital heart disease cases discovered in adulthood involving arrhythmias and valvular heart disease, TEE is likely to become more important as a means of diagnosis, and should be used correctly so as to achieve optimal diagnostic advantage. TEE should be provided by specialists not cardiologists.

Unusual giant right atrium in rheumatic mitral stenosis and tricuspid insufficiency.

Dilation and hypertrophy of the atria occur in patients with valvular heart disease especially in mitral regurgitation, mitral stenosis or tricuspid abnormalities. In sub-saharan Africa, rheumatic fever is still the leading cause of valvular heart disease. We report a case of an unusual giant right atrium in context of rheumatic stenosis and severe tricuspid regurgitation in a 58-year-old woman.
