Cardiac masses have a wide range of etiologies with the most common being thrombi and less commonly tumors. However, in Sub-Saharan Africa other etiologies not commonly seen in developed countries such as endomyocardial fibrosis (EMF) must be considered. EMF is a disease process associated with poverty, a poor diet, and eosinophilia although its pathology is poorly understood.
We report a case of a 53-year-old male with a history of dilated cardiomyopathy who presented to a Ugandan Emergency Department in respiratory distress. Bedside echocardiography was performed which revealed a large mass in the apex of the left ventricle. The patient was subsequently given supplemental oxygen and intravenous furosemide, however he later died while in the emergency department due to limited resources and lack of definitive care.
The list of potential etiologies of cardiac masses is widely variable, and in settings such as Sub-Saharan Africa, this list must be expanded to include possible diagnoses such as EMF. EMF is a diagnosis that should be considered in patients presenting with respiratory distress and a cardiac mass present on echocardiography, such as the case presented here. The limited opportunities for medical personnel to diagnose cardiovascular disease can be made more efficient by the use of diagnostic imaging devices which are portable, yet capable of diagnosing the most common local pathologies [9-11].
心脏肿物病因广泛,最常见的是血栓,肿瘤相对少见。然而,在撒哈拉以南非洲地区,必须考虑一些在发达国家不常见的病因,如心内膜心肌纤维化(EMF)。EMF是一种与贫困、不良饮食和嗜酸性粒细胞增多相关的疾病过程,但其病理机制尚不清楚。
我们报告一例53岁男性,有扩张型心肌病病史,因呼吸窘迫就诊于乌干达急诊科。床边超声心动图检查发现左心室心尖部有一巨大肿物。患者随后接受了吸氧和静脉注射速尿治疗,但由于资源有限和缺乏明确治疗,他后来在急诊科死亡。
心脏肿物的潜在病因范围广泛,在撒哈拉以南非洲等地区,该范围必须扩大,以纳入诸如EMF等可能的诊断。对于出现呼吸窘迫且超声心动图显示有心脏肿物的患者,如本文所述病例,应考虑EMF诊断。通过使用便携式但能够诊断最常见当地病理情况的诊断成像设备,可以提高医务人员诊断心血管疾病的有限机会的效率[9-11]。
