Insights
Pulmonary arterial hypertension (PAH) is a serious cardiovascular disease. This study found that established risk scores effectively predict mortality in Hispanic PAH patients, aiding treatment decisions.
Area of Science:
- Cardiology
- Pulmonology
- Clinical Research
Background:
- Pulmonary arterial hypertension (PAH) is a cardiovascular disease with a high mortality rate.
- Current PAH treatment guidelines rely on risk stratification, validated primarily in Caucasian populations.
- Limited data exists on the applicability of these prognostic tools in Hispanic PAH patients.
Purpose of the Study:
- To evaluate the effectiveness of established risk assessment tools (COMPERA, COMPERA 2.0, REVEAL 2.0) in predicting outcomes for Hispanic patients with PAH.
- To determine if baseline risk stratification provides prognostic information in this underrepresented population.
Main Methods:
- Analysis of a single-center outpatient cohort of 135 Hispanic patients diagnosed with PAH.
- Calculation of baseline characteristics using COMPERA, COMPERA 2.0, and REVEAL 2.0 risk scores prior to PAH-targeted therapy initiation.
- Assessment of 1-year survival rates and the discriminatory ability of the risk scores.
Main Results:
- The overall 1-year survival rate for the Hispanic PAH cohort was 88%.
- The COMPERA, COMPERA 2.0, and REVEAL 2.0 risk scores demonstrated similar and reasonable discrimination of mortality across different risk strata (all p < 0.001).
- Baseline risk assessment provided significant prognostic information for this cohort.
Conclusions:
- Hispanic patients with PAH experience a high mortality rate.
- Guideline-recommended baseline risk assessment tools are valuable for predicting outcomes in Hispanic PAH patients.
- These findings support the use of established risk scores for goal-directed therapy in diverse PAH populations.
Abstract:
Pulmonary arterial hypertension (PAH) is a cardiovascular disease with high mortality rate. Current guidelines propose initiation and escalation of PAH-targeted treatment based on a goal-directed approach targeting hemodynamic, functional, and biochemical variables. This approach has been successfully validated in large Caucasian cohorts. However, given the low number of Hispanic patients enrolled in large PAH trials and registries, it is unknown if the same prognostic tools can be applied to this patient population. We analyzed a single-center outpatient cohort that consisted of 135 Hispanic patients diagnosed with PAH. Baseline characteristics were calculated based on COMPERA, COMPERA 2.0 and REVEAL 2.0 risk scores before the initiation of PAH-targeted therapies. The survival rate at 1 year after diagnosis was 88% for the entire cohort. The three established risk scores to predict PAH outcomes yielded similar results with reasonable discrimination of mortality in the different risk strata (all p < 0.001). Hispanic patients with PAH have a high mortality rate. Our analysis suggests that guideline proposed risk assessment at baseline yields important prognostic information in this patient population.
