We have studied left ventricular function by non-invasive methods in 28 patients with ankylosing spondylitis and 14 with Reiter's disease and compared them with 42 normal subjects. A dilated and poorly contracting left ventricle with abnormal systolic time intervals were found in five (18%) of those with ankylosing spondylitis and two (14%) with Reiter's disease. Our results suggest that the high cardiovascular morbidity and mortality in these diseases may be due to abnormality of the myocardium in the absence of valve disease.
我们采用非侵入性方法研究了28例强直性脊柱炎患者和14例赖特综合征患者的左心室功能，并将其与42名正常受试者进行了比较。在5例（18%）强直性脊柱炎患者和2例（14%）赖特综合征患者中发现左心室扩张且收缩功能不良，收缩时间间期异常。我们的研究结果表明，这些疾病中心血管疾病的高发病率和死亡率可能是由于在无瓣膜疾病的情况下心肌异常所致。
