However, there are few data on fluid administration for patients with preexisting heart failure with reduced ejection fraction (HFrEF).<\/jats:p><\/jats:sec>Objective<\/jats:title>To evaluate the association between preexisting HFrEF, guideline-recommended intravenous fluid resuscitation, and mortality among patients with community-acquired sepsis and septic shock.<\/jats:p><\/jats:sec>Design, Setting, and Participants<\/jats:title>A cohort study was conducted of adult patients hospitalized in an integrated health care system from January 1, 2013, to December 31, 2015, with community-acquired sepsis and preexisting assessment of cardiac function. Follow-up occurred through July 1, 2016. Data analyses were performed from November 1, 2020, to August 8, 2022.<\/jats:p><\/jats:sec>Exposures<\/jats:title>Preexisting heart failure with reduced ejection fraction (\u226440%) measured by transthoracic echocardiogram within 1 year prior to hospitalization for sepsis.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>Multivariable models were adjusted for patient factors and sepsis severity and clustered at the hospital level to generate adjusted odds ratios (aORs) and 95% CIs. The primary outcome was the administration of 30 mL\/kg of intravenous fluid within 6 hours of sepsis onset. Secondary outcomes included in-hospital mortality, intensive care unit admission, rate of invasive mechanical ventilation, and administration of vasoactive medications.<\/jats:p><\/jats:sec>Results<\/jats:title>Of 5278 patients with sepsis (2673 men [51%]; median age, 70 years [IQR, 60-81 years]; 4349 White patients [82%]; median Sequential Organ Failure Assessment score, 4 [IQR, 3-5]), 884 (17%) had preexisting HFrEF, and 2291 (43%) met criteria for septic shock. Patients with septic shock and HFrEF were less likely to receive guideline-recommended intravenous fluid than those with septic shock without HFrEF (96 of 380 [25%] vs 699 of 1911 [37%]; P<\/jats:italic>\u2009&amp;lt;\u2009.001), but in-hospital mortality was similar (47 of 380 [12%] vs 244 of 1911 [13%]; P<\/jats:italic>\u2009=\u2009.83). In multivariable models, HFrEF was associated with a decreased risk-adjusted odds of receiving 30 mL\/kg of intravenous fluid within the first 6 hours of sepsis onset (aOR, 0.63; 95% CI, 0.47-0.85; P<\/jats:italic>\u2009=\u2009.002). The risk-adjusted mortality was not significantly different among patients with HFrEF (aOR, 0.92; 95% CI, 0.69-1.24; P<\/jats:italic>\u2009=\u2009.59) compared with those without, and there was no interaction with intravenous fluid volume (aOR, 1.00; 95% CI, 0.98-1.03; P<\/jats:italic>\u2009=\u2009.72).<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>The results of this cohort study
