[Contribution of the 6-minutes walking test and the plasma NT-proBNP at admission and discharge to the prognostic evaluation of patients with NYHA class II-III Heart Failure.] / Contribution du test de marche de six minutes et des taux de NT-proBNP à l'admission et la sortie dans l'évaluation pronostique de l'insuffisance cardiaque classe II-III de la NYHA.

OBJECTIVE: To study the 6MWT and NT-proBNP contribution to the prognosis evaluation of patients with NYHA class II-III heart failure in the Yalgado Ouédraogo Teaching Hospital. METHODS: We carried out a nine months prospective observational cohort from the 1st February to the 31st October 2020. Patients with NYHA class II-III HF who consented to participate were included in the study. We identified two variables of interest: death and readmission. RESULTS: We included 50 patients with congestive heart failure representing 37.3% of heart failure. The average follow up time of patients was 154.58 ± 74.8 days. Twelve patients (24%) were readmited and 11 passed away with five during hospitalisation. On admission, The average distance on the 6MWT (194.6 ± 85.5 m) on admission and average NT-proBNP (5812.1±4729.4 ng/L) measured on admission and before discharge wasn't significantly correlated to the risk of death and re-hospitalisation. The average distance on the 6MWT before discharge (306.2±84.6) was significantly correlated to an increase risk of death and re-hospitalisation. Patients with an increase in NT-proBNP superior to 30% from measurement on admission to the one before discharge had a high risk of re-hospitalisation and death compare to those with a decrease of more than 30% with a moderate to good correlation coefficient of 0.6 between the two. CONCLUSION: 6MWT and NT-proBNP variations from admission to discharge have been necessary to evaluate the prognosis of patients with CHF.

[Ventricular arrythmia and sport practice: A Gallavardin's ventricular tachycardia during exercice in healthy heart, about a case and review of the literature]. / Arythmie ventriculaire et activité sportive : tachycardie ventriculaire d'effort de Gallavardin sur cœur sain, à propos d'un cas et revue de la littérature.

Regular physical exercice has undeniable cardiovascular benefits and improves life expectancy. This benefice seems limited to moderate intensity exercises. Intense and chronic physical exercice would lead to heart structural changes. For a long time, knowledge of these cardiac effects seemed limited to the left ventricle. Since more authors have shown that right ventricle is vulnerability to the effects of intense chronic training. We report a Gallavardin-type ventricular stress tachycardia in a young with healthy hearted; in whom a right infundibular arrhythmogenic focus has been found in the absence of structural alteration of the right ventricle. Intense athletic activity may reveal a latent arrhythmogenic focus through sympathetic activation. Ablation was the preferred therapeutic strategy, preferred to drug therapy and derived from an analysis of risk-benefit ratios.

[Management and prognosis of pulmonary embolism associated with right heart thrombi: A prospective study at the University Hospital Yalgado Ouédraogo]. / Prise en charge et pronostic des embolies pulmonaires associées à des thrombi intracavitaires droits : à propos d'une série prospective au centre Hospitalier Universitaire Yalgado Ouédraogo.

OBJECTIVE: To describe the management and evolution of high risk of death pulmonary embolism associated with right heart thrombi. MATERIAL AND METHODS: We conducted a prospective cohort survey over a 54 month-period, from March 1st, 2012 to September 30th 2015. Were included all patients with pulmonary embolism and having high or intermediate-high risk of death. Patients were divided into two groups according to whether cardiac Doppler-echography found a thrombus in the right chambers or not (ICT+ vs. ICT-). The survival curves for the patients were obtained using the software STATA. RESULTS: The prevalence of pulmonary embolism associated with right heart thrombi was 4% in our study. Thrombi were mobile, straight localization in all cases. The ICT+group was characterized by a significantly higher proportion of congestive heart and chronic lung disease. The proportion of patients' thrombolysis was significantly higher in the ICT-group. In the ICT+group, thrombolysis significantly reduced mortality giving a 30-day survival of 80% against 20% among patients receiving only heparin. CONCLUSION: Pulmonary embolism associated with right heart thrombi including the atrium are not exceptional. These patients are at high risk of early death. Thrombolysis is significantly improving the mortality of pulmonary embolism associated with right-sided heart thrombi.
