Complex and Potentially Harmful Medication Patterns in Heart Failure with Preserved Ejection Fraction

: Complex medication regimens, often present in heart failure with preserved ejection fraction, may increase the risk of adverse drug effects and harm. We sought to characterize this complexity by determining the prevalence of polypharmacy, potentially inappropriate medications, and therapeutic competition (where a medication for one condition worsens another condition) in one of the few dedicated heart failure with preserved ejection fraction programs in the United States.
