Hypertension mortality could be reduced by compliance with treatments and hygienic rules. The study aimed to assess the knowledge, attitudes and practices (KAPs) towards hypertension among hypertensive patients at Tanvè (Benin) in 2018. Materials and Methods: This was a cross-sectional study. It included, people aged 25 and over, followed in Tanvè Health Study and screened hypertensive during the 2017 visit. An individual interview was used for the data collection in 2018. The evaluation of the KAPs was made by questions with two optional answers, marked 0 or 1: 24 for knowledge, 8 for attitudes and 12 for practices. The level was rated good when the score was ≥ 3rd quartile of the theoretical score. Results: A total of 380 people were surveyed, 67.9% of whom were women; the mean age was 52.4 ± 16.5 years. Among them, 22.6% had a good level of knowledge and 89.7% had good attitudes. Only 50.1% of the respondents were aware of their history of hypertension. Few of them (5.2%) had good practices towards hypertension. Conclusion: This study shows a low level of knowledge and practices towards hypertension. Interventions for the therapeutic education of hypertensive patients would be effective within the target population.

The main purpose was to study the right ventricular pacing threshold of patients who benefit from cardiac pacemaker's implantation at the National Teaching Hospital of Cotonou in Benin. This was a retrospective study from January 2007 to September 2013. The right ventricular pacing threshold measured during successive checks has been studied. A threshold greater than 1 volt was considered high. The conventional causes of threshold's rising were sought. 35 files were examined. The average threshold of our patients amounted to 1.24 ± 1.17 volts at the first control and remained high until the end of follow-up. The prevalence of threshold elevation was 17% (6/35). The causes of threshold elevation were: late displacement of the lead (1 case), faulty lead (1 case), and suspected lead's micro dislodgment (1 case). There was no formal etiology found for 3 cases. Half of threshold elevation cases involved a problem of pacing lead. Similar findings have been reported by previous studies. This study has confirmed that threshold elevation mainly involved pacemaker lead. The premature need to change the pacemaker caused by this elevation has considerable consequences in a Beninese local context marked the lack of governmental facilities.
