Frequency of cardiac involvement among patients with Ankylosing Spondylitis

Background and aims: ankylosing spondylitis (as) is an idiopathic chronic inflammatory disease mainly involves sacroiliac and axial joints; but it may also have extra-articular involvement. accordingly, this study was designed to determine the frequency of cardiac involvement among patients with ankylosing spondylitis. methods: this study was performed as a descriptive-analytical cross-sectional survey. in this study 50 consecutive patients with as and 40 normal healthy subjects were enrolled and compared for cardiologic manifestations. results: the frequency of cardiac involvement was similar between as patients and normal subjects (p>0.05). however, there was significant difference between 2 groups in point of mitral valve prolapse and mitral regurgitation (p<0.05). conclusions: totally, according to the obtained results, it may be concluded that the frequency of cardiac involvement in as patients and normal subjects were relatively similar.
