Specialty-Based Variability in Diagnosing and Managing Heart Failure With Preserved Ejection Fraction.

OBJECTIVE: To quantify differences in the diagnosis and treatment of heart failure with preserved ejection fraction (HFpEF) between cardiologists and noncardiologists, who often diagnose and manage HFpEF.

METHODS: Cardiologists and noncardiologists (internal medicine, medicine/pediatrics, family medicine, geriatrics) were anonymously surveyed between January 16, 2018, and March 2, 2018, regarding practices related to diagnosing and managing HFpEF at the University of Michigan and Weill Cornell Medical Center. Response data were compared using χ analysis.

RESULTS: Of 1010 physicians surveyed, 211 completed a significant portion of the survey: 32 cardiologists and 179 noncardiologists. Most noncardiologists were unaware of HFpEF diagnostic guidelines and commonly used left ventricular diastolic dysfunction and natriuretic peptides to diagnose HFpEF. Noncardiologists (32.3%, n=52) were less likely than cardiologists (64.5%, n= 20) to prescribe an aldosterone antagonist for HFpEF (P=.001). Both groups reported similar use of β-blockers, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and exercise programs. Noncardiologists were more likely to refer patients with HFrEF to cardiology (63.1%, n=111) compared with patients with HFpEF (33.5%, n=59; P<.001 noncardiologists="" were="" more="" likely="" to="" discuss="" prognosis="" and="" goals="" of="" care="" with="" patients="" hfref="" n="151)" than="" hfpef="" p="">

CONCLUSION: Cardiologists and noncardiologists vary significantly in their HFpEF diagnosis and treatment practices. As diagnostic criteria continue to be evaluated for HFpEF, dissemination of these guidelines to noncardiologists, with an emphasis on the morbidity and mortality associated with HFpEF, is imperative.
