The Claim

In clinically stable patients with heart failure with preserved ejection fraction, a supervised 12-month combined endurance and resistance exercise program is safe, with no acute cardiovascular events such as myocardial infarction or stroke directly related to exercise sessions. Hospitalizations adjudicated as potentially related to heart failure or exercise were numerically more frequent in the training group than in the usual care group.

Description
1 study reviewed
In plain English

For stable patients with heart failure with preserved ejection fraction, a supervised 12-month exercise program that combines endurance and resistance training is safe, causing no heart attacks or strokes during exercise sessions. However, these patients were hospitalized for heart failure or exercise-related reasons more often than patients receiving usual care.

See the scientific wording

In clinically stable patients with heart failure with preserved ejection fraction, a supervised 12-month combined endurance and resistance exercise program is safe, with no acute cardiovascular events such as myocardial infarction or stroke directly related to exercise sessions, although hospitalizations adjudicated as potentially related to heart failure or exercise were numerically more frequent in the training group than in the usual care group.

Why this might work

Exercise training makes the muscles better at using oxygen, so the heart doesn't have to work as hard during physical activity. This protects the heart from sudden damage like heart attacks or strokes. Strength training also keeps muscles strong, which makes everyday movements easier and puts even less strain on the heart.

What the research says

1 study
  1. Study: Combined endurance and resistance exercise training in heart failure with preserved ejection fraction: a randomized controlled trial

    The study tested a year of exercise training in people with heart failure and found it safe, with no immediate heart attacks or strokes during exercise and no significant increase in hospitalizations, while also improving fitness and symptoms.
