The purpose of this retrospective study covering a 10-year period was to analyze epidemiological data and associated conditions related to atrial fibrillation (AF) in a cardiology hospital setting in SubSaharan Africa.
A total of 217 charts of patients hospitalized in the Medical Department of the Abidjan Cardiology Institute between August 1995 and August 2005 were reviewed.
During the study, a total of 3,908 patients were admitted to the department, including 217 for AF for a hospital prevalence of 5.5%. There were 113 men (52%) and 104 women (48%) for a sex ratio of 1.08. Overall mean patient age was 58.9 years (range, 18 to 91 years). The difference in the mean age of men and women was not statistically significant: 57.8 versus 60 years respectively. The main symptoms at the time of admission to the hospital were exertional dyspnea (55.7%) and palpitations (22.1%). A total of 136 patients (62.6%) exhibited cardiac insufficiency. Heart disease was diagnosed in 192 patients including hypertensive cardiopathy in 48% and rheumatic valvular heart disease in 28%. The thromboembolic risk was moderate in 47% of patients (CHADS2 score, between 1 and 2) and high in 18.4% (CHADS2 score > or = 3).
In our practice, hypertensive and rheumatic valvular heart disease were the main causes of AF that was associated with an alarming thromboembolic risk. These findings indicate that further effort is needed to prevent arterial hypertension and acute rheumatic joint disease.
这项为期10年的回顾性研究旨在分析撒哈拉以南非洲一家心脏病医院中与心房颤动（AF）相关的流行病学数据及相关病症。
回顾了1995年8月至2005年8月期间在阿比让心脏病研究所内科住院的217例患者的病历。
研究期间，该科室共收治3908例患者，其中217例为心房颤动患者，医院患病率为5.5%。男性113例（52%），女性104例（48%），性别比为1.08。患者总体平均年龄为58.9岁（范围为18至91岁）。男性和女性的平均年龄差异无统计学意义，分别为57.8岁和60岁。入院时的主要症状为劳力性呼吸困难（55.7%）和心悸（22.1%）。共有136例患者（62.6%）出现心功能不全。192例患者被诊断患有心脏病，其中48%为高血压性心脏病，28%为风湿性瓣膜性心脏病。47%的患者血栓栓塞风险为中度（CHADS2评分在1至2之间），18.4%的患者风险为高度（CHADS2评分≥3）。
在我们的实践中，高血压性和风湿性瓣膜性心脏病是心房颤动的主要病因，且伴有令人担忧的血栓栓塞风险。这些发现表明需要进一步努力预防动脉高血压和急性风湿性关节疾病。
