AIM
Despite heart failure having been identified in subjects in sub-Saharan Africa over the last 60 years, there is still a dearth of data, especially echocardiographic data on heart failure. We therefore set out to analyse the clinical and echocardiographic features of all consecutive subjects presenting with heart failure in a tertiary institution in Nigeria.
METHODS
Three hundred and forty subjects with heart failure, according to the guidelines of the European Society of Cardiology, were studied. Each patient had two-dimensional guided transthoracic echocardiography.
RESULTS
The mean age of the patients was 50.60 +/- 15.29 years, and 50.9% of the study population were males while 49.1% were females. The commonest cause of heart failure identified was hypertension in 61.5% of the patients; 75.5% had systolic heart failure, whereas 23.5% had heart failure with preserved ejection fraction.
CONCLUSIONS
Untreated hypertension has been identified as the leading cause of heart failure in Abuja, Nigeria, which is similar to that in many other parts of sub-Saharan Africa. Coronary artery disease is a rare cause of heart failure in this population group.
目的
尽管在过去60年里撒哈拉以南非洲地区的人群中已发现心力衰竭病例，但仍然缺乏数据，尤其是关于心力衰竭的超声心动图数据。因此，我们着手分析尼日利亚一家三级医疗机构中所有连续出现心力衰竭的患者的临床和超声心动图特征。
方法
根据欧洲心脏病学会的指南，对340例心力衰竭患者进行了研究。每位患者均接受了二维引导经胸超声心动图检查。
结果
患者的平均年龄为50.60±15.29岁，研究人群中50.9%为男性，49.1%为女性。所确定的心力衰竭最常见病因是高血压，占患者的61.5%；75.5%为收缩性心力衰竭，而23.5%为射血分数保留的心力衰竭。
结论
未经治疗的高血压已被确定为尼日利亚阿布贾心力衰竭的主要病因，这与撒哈拉以南非洲许多其他地区相似。冠状动脉疾病是该人群组中导致心力衰竭的罕见病因。
