The prevalence, predictors, and prognostic impact of PIP in HFrEF remain unclear. Therefore, the aim was to investigate the prevalence, predictors, and outcomes of PIP in a large, real-world HFrEF population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients with HFrEF enrolled in the Swedish HF Registry (2005\u201320) were included.

The most frequent agents were neuroleptics (29%), systemic steroids (10%), and NSAIDs (6%). Independent predictors included rheumatoid arthritis [odds ratio (OR) 3.39; 95% CI, 2.92\u20133.94], depression (OR 3.06; 95% CI, 2.74\u20133.42), chronic obstructive pulmonary disease (OR 1.86; 95% CI, 1.76\u20131.98), and gout (OR 1.48; 95% CI, 1.35\u20131.62). Patients on PIP were less likely to receive GDMT. Presence of \u22651 PIP was independently associated with increased 3-year risk of HF death (HR, 1.13; 95% CI, 1.04\u20131.23), all-cause and cardiovascular death, first and recurrent HF hospitalizations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Nearly half of HFrEF patients received PIP medications, particularly those with multimorbidity, which was independently associated with worse outcomes and less GDMT use.
