Mitral valve prolapse (MVP) is a common condition that is believed to be responsible for numerous symptoms and potentially serious complications. To determine whether symptoms and functional impairment are related to MVP itself, we studied 274 outpatients referred to an echocardiography laboratory for suspicion of MVP. The age, sex, and symptoms at the time of echocardiography were similar among patients with and without evidence of MVP. After 14 to 36 months, 158 patients were interviewed. There was a high rate of dysfunction, but echocardiographic evidence of MVP was not associated with disability, health care utilization, or reported symptoms. The results of this study suggest that symptoms and dysfunction are not related to the presence of MVP by echocardiography. The functional impairment that is seen in patients suspected of MVP may be caused by other factors.
二尖瓣脱垂（MVP）是一种常见病症，被认为是众多症状及潜在严重并发症的病因。为确定症状和功能损害是否与MVP本身相关，我们对274名因疑似MVP而转诊至超声心动图实验室的门诊患者进行了研究。有MVP证据和无MVP证据的患者在超声心动图检查时的年龄、性别及症状相似。14至36个月后，对158名患者进行了访谈。功能障碍发生率较高，但MVP的超声心动图证据与残疾、医疗保健利用或报告的症状无关。本研究结果表明，症状和功能障碍与超声心动图显示的MVP存在无关。疑似MVP患者中出现的功能损害可能由其他因素引起。
