in hypertrophic papillary muscles the myocardial atp content decreased at a slower rate ( atp decay 12 % of the initial value after 60 minutes of ischemia ) than in normal papillary muscles obtained from patients with isolated mitral stenosis ( atp decay 33 % of the initial value after 40 minutes of ischemia ) .
