U.S., Dec. 9 -- ClinicalTrials.gov registry received information related to the study (NCT07270536) titled 'The Effect of Increasing The Heart Rate on Heart Filling Pressures During Exercise in People With Heart Failure With Preserved Ejection Fraction' on Nov. 14.

Brief Summary: Heart failure with preserved ejection fraction (HFpEF) is a condition where the heart pumps strongly enough, but has trouble relaxing and filling with blood properly. This causes the pressure on the left side of the heart to rise, especially during activity, which can lead to symptoms like shortness of breath and fatigue.
