Adherence
In obese older patients with HFPEF, neither caloric restriction nor aerobic exercise training significantly improves quality of life as measured by the Minnesota Living with Heart Failure (MLHF) questionnaire, although diet significantly improves other heart failure-specific quality of life measures (KCCQ).
While both diet and exercise improve your physical stamina (oxygen consumption), they may not immediately change how you score on standard heart failure quality of life surveys (MLHF). However, diet specifically improved other heart failure-specific quality of life measures (KCCQ). This suggests that while you may not feel a massive shift in your daily 'quality of life' perception immediately, your heart and muscles are functioning better, and other aspects of your health are improving.
There was no statistically significant change in MLHF total score with exercise and with diet (main effect: exercise, −1 unit [95% CI, −8 to 5], P = .70; diet, −6 units [95% CI, −12 to 1], P = .08)... Diet but not exercise significantly improved the KCCQ score, a heart failure–specific QOL measure, by 7 units (95% CI, 2.6 to 12.3; P = .004).
Why this rating
Randomized clinical trial with high statistical power for the primary outcomes.
