To assess the prevalence of echocardiographic and Doppler abnormalities in psoriatic arthritis (PsA) patients without clinically evident cardiovascular manifestations or classic atherosclerosis risk factors.
Fifty PsA patients were recruited from Hospital Xeral-Calde, Lugo, Spain. Patients seen during the period of recruitment that had classic cardiovascular risk factors or had suffered cardiovascular or cerebrovascular events were excluded. Fifty healthy matched controls were also studied. Echocardiographic and Doppler studies were performed in all cases and controls.
In PsA patients the frequency of aortic and tricuspid (10%) and mitral regurgitation (16%) was not different from that seen in matched controls (10, 4, and 12%). Also, the pulmonary artery systolic pressure was normal in the group of PsA patients (23.4+/-3.9 mm Hg). The prevalence of diastolic dysfunction, in all cases due to impaired relaxation, was similar in PsA patients (28%) and controls (24%) (P=0.65). In addition, no significant echocardiographic and Doppler differences were observed when PsA patients with polyarticular pattern were compared with the remaining PsA patients.
The present study shows that actively treated PsA patients without cardiovascular risk factors or clinically evident cardiovascular disease do not exhibit silent subclinical echocardiographic abnormalities.
