چکیده

BACKGROUND Pulmonary arterial hypertension (PAH) is a major cause of morbidity and mortality among patients with systemic sclerosis (SSc). Early detection and prompt treatment of PAH associated with SSc (SSc-PAH) result in better prognosis. We conducted echocardiographic study to presume the prevalence of PAH in Korean adult SSc patients and to diagnose SSc-PAH in their early stages with right heart catheterization (RHC). METHODS We performed free of charge echocardiographic study including 37 adult SSc patients at the Chungnam National University Hospital. The possibility of PAH is determined by the estimation of pulmonary arterial pressure by peak tricuspid regurgitation velocity of > 3.0 m/s. Patients with possible PAH were recommended to undergo RHC to confirm the diagnosis. RESULTS In 37 patients, 8 patients were suspected with PAH. Among them, 6 patients agreed to be examined with RHC, and 4 were confirmed with PAH. The prevalence of possible PAH was 21.6% (8 of 37 patients), and that of confirmed PAH was 10.8% (4 of 37 patients). Four patients who were confirmed with SSc-PAH through RHC have been treated with specific pulmonary vasodilators and maintained stable. CONCLUSION Eight patients (21.6%) were possible PAH and 4 (10.8%) were diagnosed as SSc-PAH by RHC after the echocardiographic screening study of 37 adult SSc patients.

The Importance of Echocardiographic Screening for Pulmonary Arterial Hypertension in Korean Patients with Systemic Sclerosis

Recognition of pulmonary arterial hypertension (PAH) associated with systemic sclerosis (SSc) (SSc-PAH) is very important , because SSc-PAH is highly prevalent and is a leading cause of mortality in patients with SSc. 1)2) Despite the use of novel therapeutic strategies, response to PAH-targeted therapy is still insufficient in SSc-PAH, which is associated with poor prognosis in SSc-PAH. 3) Ind...

THE EFFECTS OF CAPTOPRIL ON PULMONARY AND SYS TEMIC ARTERIAL PRESSURES IN HIGHALTITUDE PULMONARY HYPERTENSION

The purpose of this investigation was to assess the effect of captopril on both systemic (P.a) and pulmonary arterial pressures (PPA) in patients with high-altitude pulmonary hypertension (HAPH). Seventeen patients (mean age 44±6.8 years) with HAPH and mild to moderate systemic arterial hypertension were included in the study. All patients underwent right heart catheterization with measurem...

Screening patients with scleroderma for pulmonary arterial hypertension and implications for other at-risk populations.

Pulmonary arterial hypertension (PAH) is a progressive vasculopathy that is advanced by the time symptoms develop. As symptoms are nonspecific and the condition uncommon, continued progression toward end-stage disease occurs for an average of 2 years between symptom onset and diagnosis. There is need for earlier diagnosis and treatment, as most patients are severely symptomatic when diagnosed a...

Pulmonary arterial hypertension (PAH) is a progressive disease with high morbidity and mortality rates. Research has shown that PAH has a prevalence rate of 10-79% in thalassemia major patients. This cross-sectional study was carried out in 2014 to determine the prevalence and risk factors of PAH in all thalassemia major patients of over 18 years of age in Ilam, Iran. A cardiologist measured sy...
