These markers identify high-risk patients for monitoring; hypothesis-generating for risk models but should not yet change practice in primary pulmonary hypertension.
What clinical, radiographic, and hemodynamic factors predict life expectancy in patients with primary pulmonary hypertension?
In primary pulmonary hypertension, signs of right heart failure, right heart strain, high pulmonary resistance, and low cardiac output are strong predictors of poor survival.
Rozkovec et al. (1986) studied this question.
