Performance of electrocardiographic criteria for detecting LVH in hypertensive Africans.

AIMS: To evaluate the performance of the currently accepted LVH electrocardiographic (ECG) criteria from ethnic-specific normal values. METHODS AND RESULTS: We included 309 hypertensive subjects with both ECG (12­leads device) and echocardiographic analysis. The diagnosis of LVH was established by echocardiography from specific norms. Current ECG criteria for the diagnosis of LVH have low performances. Area Under Curve of Sokolow-Lyon, Peguero-Lo Presti, Cornell voltage and Cornell Product were respectively 0.61, 0.65, 0.72 and 0.71. CONCLUSION: In hypertensive African, the most accurate criterion for diagnosing LVH is Cornell voltage.

Knowledge, attitudes and practices of general practitioners on peripheral neuropathies in Benin in 2021.

PURPOSE: First healthcare actors in neurological diseases management, General Practitioners (GPs) still limited in the assessment of Peripheral Neuropathies (PN). This study assesses the knowledge, attitudes, practices (KAP) of GPs on PN in Benin in 2021 and identifying associated factors to low KAP. MATERIALS AND METHODS: It was a cross-sectional study conducted from 20 November 2020 to 30 June 2021 which included GPs registered in the National Order of Physicians in Benin and interns in last year of medical studies (MS). An overall KAP score of 24 points was derived. KAP levels were low (score < 17), medium (17 to 19) and high (score ≥ 20). Multivariable regression models were performed to identify factors associated with low KAP. RESULTS: 645/1,066 participants (60.5%) were included in the study with median age 28 years [Interquartile range IQR: 26-30 years], and 442 (68.5%) were male. The KAP level was low in 70.1%. 16.7% had a low knowledge of polyneuropathy manifestations, 35% perceived PN as an incurable disease. Lack of knowledge on PN before MS (adjusted Odds-ratio aOR = 1.6 [95% confidence interval CI: 1.1-2.3]), and no postgraduate training on PN (aOR = 1.8 [95% CI: 1.--3.0]) were associated with low overall KAP level. Working in rural area (aOR = 0.4 [95%CI: 0.2-0.7]), and being an intern (aOR = 0.6 [95%CI: 0.4-0.9]) were associated with better overall KAP level. CONCLUSION: This study highlights the need for better training with strong emphasis on PN during the MS and the organization of postgraduate training for GPs; the cornerstone for improving the management of PN in Benin.

Influenza vaccination coverage and determinants of vaccination in peripheral arterial disease patients.

Background: In the latest American Heart Association guidelines, influenza vaccination is recommended for patients with peripheral arterial disease (PAD). The vaccination coverage in this specific population is currently unknown. This study aims to determine the adherence to influenza vaccination in a PAD population and identify associated determinants. Patients and methods. Hospitalized patients and outpatients with PAD from two university departments of vascular medicine were prospectively included. A questionnaire was administered to collect sociodemographic data, cardiovascular risk factors, influenza vaccination status, history of cardiovascular disease, and perception and knowledge about vaccination. Logistic regression was conducted to assess vaccination determinants. Results: Over a six-month period, 494 patients were included (median age 69.5, IQR [63-77], 78% male). Overall, 60.1% were either vaccinated or intended to be (Group 1). Vaccination was associated with age (odds-ratio [OR]=1.055, 95% confidence intervals [95%CI]: 1.035-1.075, p<0.0001), abdominal aorta aneurysm (OR=0.390, 95%CI: 0.229-0.664, p=0.001), chronic obstructive pulmonary disease (OR=0.545, 95%CI: 0.367-0.810, p=0.003), chronic renal disease (OR=0.630, 95%CI: 0.400-0.993, p=0.046), and valvulopathy (OR=2.444, 95%CI: 1.122-5.326, p=0.025). Only 25.3% received vaccination information mainly from their general practitioners. Among patients against vaccination, 59.9% considered themselves not concerned about potential influenza consequences on their PAD, and 37.6% did not intend to change their decision. Conclusions: This study highlights the low adherence to influenza vaccination in the PAD population of 2 university hospital centers. Vaccination is often related to age, and there is a need for adapted information regarding influenza consequences on cardiovascular disease overall, particularly on PAD. Addressing common information and advice about vaccination will be a challenge.

Recomendações para Avaliação por Imagens das Próteses Valvares Cardíacas / Recommendations for the Imaging Assessment of Prosthetic Heart Valves

Disfunção de prótese valvar cardíaca (PVC) é rara, porém é uma potencial ameaça à vida. Estabelecer o exato mecanismo da disfunção da PVC é desafiador, no entanto é essencial para determinar a estratégia terapêutica apropriada. Na prática clinica, uma abordagem abrangente que integra vários parâmetros de morfologia e função avaliados pelo eco transtorácico 2D/3D e transesofágico são fundamentais para detectar e quantificar a disfunção da PVC. A cinefluoroscopia, a tomografia computadorizada com multidectetores, a ressonância magnética cardíaca, e em menor escala, a imagem nuclear, são ferramentas complementares para o diagnóstico e abordagem das complicações das PVC. Este documento apresenta recomendações para o uso de imagem em multimodalidade para avaliação das PVCs
