The aim is to assess early right ventricular systolic dysfunction in psoriatic arthritis patients using RV strain echocardiography

Previous studies evaluated RV strain for detection of subclinical RV affection due to PAH in systemic lupus erythematosus. However , to our knowledge , the study of RV strain and its possible association with serum endostatin to detect subclinical right ventricular systolic dysfunction and its relation to PAH in PsA patient is still a novel. Our aim is to assess early right ventricular systolic dysfunction in psoriatic arthritis patients using RV strain Echocardiography.

To evaluate serum endostatin as an objective biomarker for Pulmonary arterial hypertension.

Inclusion Criteria:
