Primary Outcome Measures:
  • The placebo-corrected change from baseline to week 24 in 6-minute walk distance [ Time Frame: Measured at 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Time from randomization to clinical worsening [ Time Frame: Measured at 6 months ] [ Designated as safety issue: No ]
    Clinical worsening was defined as death, the first occurrence of hospitalization for pulmonary arterial hypertension, or initiation of PAH-specific drug therapy

  • Change from baseline to week 24 in World Health Organization functional class [ Time Frame: measured at 6 monthes ] [ Designated as safety issue: No ]
    World Health Organization (WHO) functional class: an adaptation of the New York Heart Association classification.

  • Change from baseline to week 24 in Borg dyspnea score [ Time Frame: measured at 6 monthes ] [ Designated as safety issue: No ]
    Borg dyspnea score: with 0 representing no dyspnea and 10 maximal dyspnea.

  • Change from baseline to week 24 in hemodynamic parameters derived from right heart catheterization. [ Time Frame: measured at 6 monthes ] [ Designated as safety issue: No ]
    Hemodynamic parameters: mean pulmonary artery pressure, right atrial pressure, cardiac index and pulmonary vascular resistance.

Study Completion Date: May 2010
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Atorvastatin group: receive atorvastatin 10 mg daily in addition to supportive care
Drug: Atorvastatin
Patients were assigned to receive 10 mg of atorvastatin for 6 months (supplied by JiaLin Pharmaceutical Co., Beijing, China). The dose was adjusted to 5mg daily if serum transaminase levels increased by less than three times the upper limit of normal or creatine kinase levels increased to less than five times the upper limit of normal. If serum transaminase and creatine kinase levels remained normal and low-density lipoprotein level greater than 3.4mmol/L after 4 weeks of therapy, the dose of drug was increased to 20mg once daily.
Other Name: atorvastatin: a'le(bland names)
Placebo Comparator: 2
Placebo group: receive matching placebo in addition to supportive care.
Drug: Placebo
Patients were assigned to receive 10 mg of placebo for 6 months (supplied by JiaLin Pharmaceutical Co., Beijing, China). The dose was adjusted to 5mg daily if serum transaminase levels increased by less than three times the upper limit of normal or creatine kinase levels increased to less than five times the upper limit of normal. If serum transaminase and creatine kinase levels remained normal and low-density lipoprotein level greater than 3.4mmol/L after 4 weeks of therapy, the dose of drug was increased to 20mg once daily.
Other Name: matching placebo: a'le(brand name)

Detailed Description:

PAH is characterized by dyspnea, fatigue, and lower extremity edema as a result of heart failure. Several research have proved that inflammation may participate in the pathogenesis of PAH. As atorvastatin inhibits inflammation and has beneficial effects on blood vessels in other types of cardiovascular disease. Therefore, atorvastatin may similarly benefit patients with PAH. Experimental data suggest that statins attenuates pulmonary hypertension in animal experiments. In addition, non-controlled clinical studies suggest that atorvastatin is effective and safe in patients with pulmonary hypertension.

Participants in this study will be randomly assigned to receive 6 months of daily placebo tablets or daily atorvastatin in a double-blind fashion. The study will compare the safety and efficacy of placebo and atorvastatin.
