Abstract

Objective: There is a paucity of data regarding intentional weight loss in obese heart failure patients. This study sought to ascertain the safety and effectiveness of a lifestyle modification program in patients with systolic heart failure and metabolic syndrome.

Methods: Patients (n=20) with systolic heart failure (ejection fraction < 50%) and metabolic syndrome were randomized to standard medical therapy (Control) versus medical therapy and lifestyle modification (Lifestyle) and followed prospectively for 3 months. Lifestyle modification involved a walking program and reduced calorie diet with 2 meal replacement products (Slim Fast®) daily. Patients attended weekly meetings with a dietitian for 12 weeks. Endpoints were obtained at baseline and 3 months and included physical exam, laboratory values, quality of life questionnaire, 6 minute walk, and brachial ultrasound.

Results: At 3 months, 5 patients in each group had lost weight. Excluding 1 patient in each group who had increased diuretic dosing, the overall change in weight was -0.84 ± 3.82 and -0.50 ± 3.64 kg (p=0.85) in the control versus lifestyle groups respectively. No significant differences in the defined endpoints were noted. None of the patients had an adverse event that was related to weight loss or exercise.

Conclusions: This study is the first to assess the effects of a comprehensive program of dietary, behavioral, and exercise modifications in this population. Institution of lifestyle modification in patients with systolic heart failure and metabolic syndrome was well tolerated, but did not result in significant weight loss.
