8. Caregiver burden • Emergent themes were • stresses on physical and mental well-being, • Stress on social and personal lives, • Threats to financial security and career paths. • The interviewees reported a sense of isolation as related to dealing with a disease that is relatively unknown to the majority of friends and family.

9. “The unwillingness to admit to their loved-ones, or indeed to themselves, that the caregiver role was taxing, augmented the sense of isolation”

25. Multivariate predictors of 1 year outcome in REVEAL Predicting survival in pulmonary arterial hypertension: insights from the Registry to Evaluate Early and Long-Term Pulmonary Arterial Hypertension Disease Management (REVEAL). Benza RL; Miller DP; Gomberg-Maitland M; Frantz RP; Foreman AJ; Coffey CS; Frost A; Barst RJ; Badesch DB; Elliott CG; Liou TG; McGoon MD Figure 2. Cox proportional-hazards estimates for multivariable model of survival, limited to terms included in the final stepwise model. Parameters significantly associated with 1-year survival only in univariable analyses included the Borg dyspnea scale, right ventricular dysfunction, pulmonary vascular resistance (PVR) index, pulmonary capillary wedge pressure, cardiac index, mean pulmonary artery pressure, and total serum bilirubin. Candidate predictor variables that were not significant at the univariable level included Tei index, vasoreactivity, race, newly diagnosed PAH, and income. Missing Borg scale and missing PVR index were both associated with lower-than-average observed survival and were therefore considered candidate predictor variables. APAH indicates associated I PAH; ECHO, echocardiogram; FPAH, familial PAH; mRAP, mean right atrial pressure; PoPH, portopulmonary hypertension; and RHC, right heart catheterization. *Reference category: NYHA/WHO functional class (Fn) II or missing. +If N-terminal proBNP is available and BNP is not, listed cut points are replaced with 1500 pg/mL. ++Restricted to tests performed within 1 year of enrollment; otherwise, the indicator is set to 0.

Combination therapy • 26 observational studies and 5 randomized trials were identified. • PDE-5 inhibitor and prostanoids,6/7 studies reported improvement in 6MWD, 6/8 studies reported improvement in functional class, 6/6 studies reported improvement in hemodynamics and 1/2 trials demonstrated improvement in quality of life and time-to-clinical worsening. • ERA and prostanoids, 4/6 studies and 1 trial reported improvement in 6MWD, 3/3 studies and 1/4 trials reported improvement in functional class, 4/5 studies and 1/4 trials reported improvement in PAP. • ERA and PDE-5 inhibitor, 4/7 studies reported an improvement in 6MWD, and 2/6 studies report improvement in functional class.
