When pulmonary hypertension secondary to scleroderma related interstitial lung disease, left-sided cardiac insufficiency and thrombo-embolic disease is also taken into account, the frequency of pulmonary hypertension in systemic sclerosis may be as high as.50%. Recent investigations brought new information considering the pathogenesis of pulmoanry hypertension and allowed new therapeutic approches to be introduced. Early diagnosis of pulmonary hypertension is a key issue in clinical practice, but it is a challange in patients with systemic disease such as systemic sclerosis.
