This study analyzed the charts of 743 black patients who visited the emergency rom of a Nashville Hospital with symptoms of chest pain, palpitation, or fatigue. One hundred sixty-five met the criteria for the diagnosis of mitral valve prolapse (MVP). Epidemiologic factors of symptomatic MVP in blacks (ie, symptoms reported based on age and sex) were examined to determine whether there are significant differences in the prevalence of symptomatic MVP with relation to black males and females. Similarities were found in the patterns of the ages of both males and females and the symptoms that were reported. No significant differences were found between black males and females, which does not support previous findings.
本研究分析了743名因胸痛、心悸或疲劳症状前往纳什维尔一家医院急诊科就诊的黑人患者的病历。165人符合二尖瓣脱垂（MVP）的诊断标准。对黑人中有症状MVP的流行病学因素（即根据年龄和性别报告的症状）进行了检查，以确定有症状MVP的患病率在黑人男性和女性之间是否存在显著差异。在男性和女性的年龄模式以及报告的症状方面发现了相似之处。在黑人男性和女性之间未发现显著差异，这与之前的研究结果不符。
