The survival in patients with pulmonary hypertension can be estimated from the patient's hemodynamic findings. Mortality is most closely associated with right ventricular hemodynamic function.
survival at given year =
= ((0.88 - (0.14 * (year)) + (0.01 * ((year) ^2))) ^ (function))
function =
= EXP((0.007325 * (mean pulmonary arterial pressure in mm Hg)) + (0.0526 * (mean right atrial pressure in mm Hg)) - (0.3275 * (cardiac index)))
where:
• year is 1, 2 or 3 years
• survival at year 1 = 0.75 ^ (function)
• survival at year 2 = 0.64 ^ (function)
• survival at year 3 = 0.55 ^ (function)
