Effect of DASH Eating Pattern on Heart Failure Outcomes

The objective of the study is to examine the effect of nutritional intake on cardiometabolic, inflammation, and physical function markers in advanced heart failure patients using a one-group pre-post test design feeding trial. Effects on hemodynamic markers will be assessed in a subsample of patients with implanted hemodynamic monitoring devices (CardioMEMS). The pre-test condition is represented by participants' self-selected diet, and the post-test condition is represented by a prescribed Dietary Approaches to Stop Hypertension (DASH) diet.
