At univariable analysis, PAH vasodilator therapy was associated with death (Cox univariable hazard ratio, 1.83; 95% CI: 1.026, 3.266; P = .04) (log-rank χ 2 = 4.314, P = .04). However, when entered as a dummy variable with septal angle or hemodynamic parameters, it did not reach statistical significance ( P = .26).
