Exercise Training in Diastolic Heart Failure

Paciente / Población Intervención / Exposición Comparación Desenlace

In 322 patients with heart failure and preserved ejection fraction, 12 months of supervised endurance and resistance training did not significantly improve a hierarchical composite of death, hospitalisation, peak oxygen uptake, diastolic function and symptoms compared with usual care, although peak oxygen uptake and NYHA class improved.

Discusión y crítica

The hierarchical primary endpoint weights death and hospitalisation so heavily in an elderly comorbid cohort that it swamped the functional signal — an endpoint-selection failure as much as a therapeutic one. It is the largest and longest randomised training trial in HFpEF and its gains in peak oxygen uptake and NYHA class are the evidence behind offering structured exercise.
