BACKGROUND: Smoking prevalence and its association with pulmonary arterial hypertension (PAH) outcomes have not been described in patients in the United States.
METHODS: Using the US-based Registry to Evaluate Early and Long-term PAH Disease Management (REVEAL), the prevalence, demographics, and outcomes in ever- versus never-smokers with PAH were determined.
RESULTS: Ever-smoking status was more prevalent in males (61.7%) than in females (42.9%) enrolled in REVEAL. Ever-smokers were older than never-smokers at the time of PAH diagnosis and REVEAL enrollment. The time to first hospitalization, transplant-free survival, and survival did not differ between ever- and never-smokers overall; however, in newly diagnosed males, ever-smoking was associated with earlier death (hazard ratio [HR] 1.8, 95% confidence interval [CI] 1.1-3.0; p = 0.0199), the composite of transplant or death (HR 2.2, 95% CI 1.4-3.6; p = 0.0008), and first hospitalization (HR 1.8, 95% CI 1.2-2.7; p = 0.0063), though smoking exposure (pack-years) did not differ between newly and previously diagnosed males.
CONCLUSIONS: REVEAL PAH data demonstrate that smoking prevalence in male PAH patients is disproportionate. The prevalence of cigarette smoking was significantly higher in males than females enrolled in REVEAL. Ever-smoking status was associated with increased age at PAH diagnosis and, in newly diagnosed male PAH patients, earlier time to hospitalization and shorter survival after PAH diagnosis.
