Forty patients, 30 men and 10 women with an average age of 38.47 +/- 11.07 years, suffering from ankylosing spondylitis and attending a Rheumatology Outpatient Clinic, were evaluated for cardiovascular involvement. The evaluation was based on patients' clinical observation, electrocardiography, echocardiography, and chest x-ray. More than a simple review, this study was undertaken with the aim of arriving at a better clinical definition of the cardiovascular manifestations found in ankylosing spondylitis. In fact, of the 40 patients, 8 (20%) had systemic hypertension for which an explanation could not be found, 4 of whom were less than forty-five years old; the echocardiogram showed mitral valve prolapse in 4 patients (10%), 2 of them with a systolic murmur and other 2 with a protosystolic click on auscultation. More significant than the changes in conduction was the finding of a sinus bradycardia in 9 patients (22.5%), and a PR interval below 120 msec in 3 patients (7.5%). The authors conclude that the extension of cardiovascular changes in ankylosing spondylitis is more vast than usually acknowledged.

Aortic insufficiency, myocardial fibrosis and conduction disturbances are known complications of ankylosing spondylitis (AS). However, few studies have assessed left ventricular diastolic function and no data are available about P-wave analysis. In this study 88 AS patients and 31 healthy volunteers underwent clinical examination, electrocardiography, echocardiography and signal-averaged P-wave analysis for the evaluation of asymptomatic cardiac involvement. The aortic root in AS patients was larger and this was correlated with the duration of the disease. Five of 88 AS patients (5.7%) had evidence of mitral valve prolapse, six (6.8%) had thick and redundant mitral valves without prolapse, five (5.7%) had mild mitral regurgitation, two had moderate (2.3%) and two had mild (2.3%) aortic regurgitation. Examination of diastolic function revealed a lower peak of E-wave velocity (E) and E/A ratio, a higher peak of A-wave velocity (A) and acceleration rate of the A wave, a longer deceleration time of E-wave velocity and isovolumic relaxation time in the AS group compared to controls. Mean filtered P-wave duration (PWD) in AS was similar to that of controls. However, PWD in AS patients was positively correlated with left atrial dimension and acceleration rate of the A wave and negatively correlated with E and E/A ratio. In conclusion, cardiac involvement may be seen in AS patients in the absence of clinical manifestations. Echocardiographic examination of diastolic function can be used in this asymptomatic period. Further studies are needed to clarify the prognostic significance of diastolic abnormalities and the value of P-wave analysis in cardiac evaluation of these patients.

Cardiovascular manifestations of seronegative spondyloarthropathies represent an important clinical problem which has not been fully elucidated. Clinically significant cardiovascular symptoms are present in 10% of patients with ankylosing spondylitis (AS), usually in the case of long-standing disease. The following echocardiographic abnormalities have been reported in AS: ascending aortitis, aortic insufficiency (1-34%), mitral insufficiency (1-76%), mitral valve prolapse (5.7-10%), and diastolic dysfunction (20-50%). Abnormalities of the cardiac conduction system may develop in 1% to 33% of AS patients as a consequence of postinflammatory scarring of the myocardium. Cardiovascular diseases are the leading cause of death (36.2%) of patients with psoriatic arthritis (PsA). The risk of death in PsA is 1.3 times greater than in the general population. The following echocardiographic abnormalities can be seen in PsA: fibrinous pericarditis (18.2%), myocarditis (15.9%), and valvular disease (5.7%). Diastolic dysfunction in PsA correlates with the presence of articular lesions and duration of psoriasis. The importance of a thorough investigation of the cardiovascular system in patients with seronegative spondyloarthropathies is emphasized.
