Sildenafil for heart failure does not result in significant improvement in exercise capacity Among patients with heart failure with preserved ejection fraction (a measure of heart function), administration of sildenafil (commercially known as Viagra) for 24 weeks, compared with placebo, did not result in significant improvement in exercise capacity or clinical status, according to a study published online by JAMA.
