Baseline and Serial Brain Natriuretic Peptide Level Predicts 5-Year Overall Survival in Patients With Pulmonary Arterial Hypertension: Data From the REVEAL Registry.

ABSTRACT: BACKGROUND:Plasma brain natriuretic peptide (BNP) level is a prognostic biomarker in pulmonary arterial hypertension (PAH). Its impact on long-term overall survival (OS) was investigated in the Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management (REVEAL), a 5-year observational, multicenter, US registry of patients with PAH. METHODS:Patients were ? 18 years of age, met right heart catheterization criteria at rest, had World Health Organization group I PAH, and had BNP measurement at enrollment. Optimal BNP threshold was obtained via receiver operating characteristic curve analysis. OS was compared in patients with low (? 340 pg/mL) vs high (> 340 pg/mL) BNP at baseline; changes between baseline and last assessment were also examined. Patients were categorized based on baseline (low or high) and follow-up (low or high) BNP values; hazard ratios (HRs) for OS were estimated and compared using Cox regression. RESULTS:Overall, 1,426 patients were analyzed. Mortality risk was significantly higher in patients with baseline high vs low BNP (HR, 3.6; 95% CI, 3.0-4.2). BNP change analysis at ? 1 year postenrollment demonstrated that the low-low group had the lowest and the high-high group had the highest 5-year mortality risk (HR, 0.23; 95% CI, 0.19-0.27). Changes in BNP score also correlated with change of risk of death. CONCLUSIONS:Baseline BNP threshold of 340 pg/mL strongly predicted survival up to 5 years in patients with PAH. A BNP reduction at 1 year since enrollment was associated with decreased mortality risk, whereas an increase in BNP at 1 year was associated with an increased mortality risk, supporting BNP as a surrogate marker of PAH survival.

Project description:BackgroundThe treatment, genotyping, and phenotyping of patients with World Health Organization Group 1 pulmonary arterial hypertension (PAH) have evolved dramatically in the last decade.Research questionThe United States Pulmonary Hypertension Scientific Registry was established as the first US PAH patient registry to investigate genetic information, reproductive histories, and environmental exposure data in a contemporary patient population.Study design and methodsInvestigators at 15 US centers enrolled consecutively screened adults diagnosed with Group 1 PAH who had enrolled in the National Biological Sample and Data Repository for PAH (PAH Biobank) within 5 years of a cardiac catheterization demonstrating qualifying hemodynamic criteria. Exposure and reproductive histories were collected by using a structured interview and questionnaire. The biobank provided genetic data.ResultsBetween 2015 and 2018, a total of 499 of 979 eligible patients with clinical diagnoses of idiopathic PAH (IPAH) or familial PAH (n = 240 [48%]), associated PAH (APAH; n = 256 [51%]), or pulmonary venoocclusive disease/pulmonary capillary hemangiomatosis (n = 3 [1%]) enrolled. The mean age was 55.8 years, average BMI was 29.2 kg/m2, and 79% were women. Mean duration between symptom onset and diagnostic catheterization was 1.9 years. Sixty-six percent of patients were treated with more than one PAH medication at enrollment. Past use of prescription weight loss drugs (16%), recreational drugs (27%), and oral contraceptive pills (77%) was common. Women often reported miscarriage (37%), although PAH was rarely diagnosed within 6 months of pregnancy (1.9%). Results of genetic testing identified pathogenic or suspected pathogenic variants in 13% of patients, reclassifying 18% of IPAH patients and 5% of APAH patients to heritable PAH.InterpretationPatients with Group 1 PAH remain predominately middle-aged women diagnosed with IPAH or APAH. Delays in diagnosis of PAH persist. Treatment with combinations of PAH-targeted medications is more common than in the past. Women often report pregnancy complications, as well as exposure to anorexigens, oral contraceptives, and/or recreational drugs. Results of genetic tests frequently identify unsuspected heritable PAH.
