The clinical and prognostic characteristics of PAH patients according to loop diuretic use remain unexplored. In this study, we retrospectively analysed the characteristics and survival of PAH patients requiring different doses of loop diuretics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>Patients diagnosed with PAH between 2001 and 2022 at seven European centres for the management of PAH. According to the median equivalent dose of furosemide in the overall cohort, patients were divided into two subgroups: no\/low-dose loop diuretic and high-dose loop diuretic. Primary outcome was 5 year all-cause mortality. Among the 397 patients included, 227 (57%) were treated with loop diuretics. Median daily furosemide equivalent dose was 25 mg, and accordingly patients were divided in no\/low dose (i.e. \u226425 mg, n = 257, 65%) vs. high dose (i.e. &amp;gt;25 mg, n = 140, 35%). Patients in the high-dose group were older, more likely to have comorbidities, and had a more severe disease according to the ESC\/ERS risk category. Crude 5 year survival was significantly shorter in patients in the high-dose group, but after adjustment for age, sex, and risk category, high loop diuretic dose was not significantly associated with the primary outcome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Use of high dose of loop diuretics in PAH is associated with a higher burden of comorbidities, more severe disease, and worse survival.
