Pulse Pressure as a Risk Factor of Atrial Fibrillation in Black African Elderly Patients

Abstract

Objective: The aim of this study was to show the prognostic role of High Pulse Pressure (PP) in the occurrence of atrial fibrillation in Black African elderly patients. Materials and Methods: In a comparative retrospective study related to 2000 patients admitted to the Institute of Cardiology of Abidjan, from January 1991 to December 2010 for atrial fibrillation, we matched pulse pressure and atrial fibrillation in Black African elderly patients. Results: The mean age of patients was 65 ± 10 years. Patients with high pulse pressure were 4.8 times more at risk to present atrial fibrillation than those with normal pulse pressure. The threshold of high risk pulse pressure was 65 mmHg. Conclusion: Pulse pressure is a factor of bad prognosis of atrial fibrillation in Black African elderly patients.

Comparação entre a rigidez vascular dos pacientes idosos com e sem fibrilação atrial

“…A hipertensão arterial (HA) é uma doença crônica com prevalência elevada nos idosos e considerada fator de risco modificável para doenças cardiovasculares (CHU et al, 2013;MALACHIAS et al, 2016 (MITCHELL et al, 2007;KOFFI et al, 2015).…”

“…A PP está mais associada com a previsão do risco para FA do que a PS (ROETKER et al, 2014;KOFFI et al, 2015). Além disso, a PP ainda foi associada com a rigidez arterial, principalmente dos grandes vasos, que também é considerada fator de risco para a FA.…”

“…A PP, determinada pela amplitude da onda de pulso ejetada pelo ventrículo, depende de propriedades da aorta proximal (CALUWÉ et al, 2018). Esse componente pulsátil, é considerado um preditor de rigidez arterial e fator de risco para desenvolvimento da FA (MITCHELL et al, 2007(MITCHELL et al, , 2008KOFFI et al, 2015).…”
